In the Zichen Hall, the fragrant nanmu that was swallowed by the bronze crane furnace was torn into wisps of residual smoke by the north wind. Yuan Wu pinched the border's fingers that were urgently reported to him and pressed out fine folds on the silk book. When his eyes swept over the "7,400 feet", the copper leakage at the corner of the hall happened to drip the first drop of water at the hour.

"The Chu people's Tianyuan is so powerful!" He suddenly threw the emergency report on the dragon's case: "Is it that my Qin's heaven is going to be covered by them? Within three days, find an solution for me!"

More than 20 black-robed officials were sweating at the foreheads, holding yellowed ancient books to form a fan in front of the long bronze desk.

Emperor Yuanwu stood in front of the hall with his hands behind his back. The morning light stretched his shadow to the wall covering the territory map of Jiuzhou, as if he had a layer of gold edge to the Lianmian Mountains. The scorched earth samples sent from Hangu Pass in the distance were shining with a strange purple light in the glass cup.

In the ancient books spread out on the table, an illustration with a dark blue light on a page overlaps with the outline of Tianyuan in the Hangu Pass - it is a faded fragment of the "God King Heavenly Palace" recorded in "The Secret World Tour of Heaven".

The ink-painted floating palace is being pulled by nine mysterious dragons, and the eaves of twelve gold jade are covered with star-shaped runes.

The mottled ancient seal notes below read: "The clear ones float upwards to become heavenly boats, the turbid ones condense into earth anchors, and the yin and yang wheels rotate and the hanging pavilion rises... The principle of these two qi rise and fall is like a floating gourd in water."

"It's like a boat sailing on the water!" The craftsman suddenly beat his knees: "When I was young, I was escorting military rations with the canal ship, and the thousand-stone cargo ship drank only more than a meter of water. If the two clear and turbid energy are regarded as the current air and 'water', the floating vehicle is the ship sailing in the sea of ​​clear air!"

"There are also sayings in ancient books that 'The hurricane was born under the wings of the peng, not because of force or force'." He bent his thin fingers, grabbed the bamboo paper on the desk and drew: "Suppose each pound of black iron needs fifteen hu of clear air to hold it up, and calculate it according to the load load of the Chu army's Tianyuan..."

A sneer came from the corner.

Mr. Chen, who was studying ancient runes, shook half of the volume of "Yunxu Kao" and poked his finger at a certain star map: "The floating warships of the You Dynasty rely on the twenty-eight constellations. What's the use of these common things?"

He suddenly coughed violently, and the yellowed silk fell to the ground, revealing a half-word "The earth's veins are traction like magnets attracting each other."

"Then have you successfully restored the Youchao Star Formation?" The Armed Forces Academy retorted sarcastically: "Your Majesty is asking for a feasible plan, not such false talks that stay on paper!"

"So you can come up with practical technology?"

"How can't it be?"

Yuan Wu narrowed his eyes and swept over the disputed ministers, and the sword intent in his sleeve quietly cut the third carving of the hall pillar. Everyone was silent in an instant, leaving only the bronze wind chimes on the eaves jingle.

“Start from the easiest.”

The emperor bent his fingers and bounced the moth that fell on the memorial, "This morning, I saw that when the kitchen steamer was lifted, the trunk cloth was bulging with heat. If the giant sack was sewn to store the fire, can it be carried by people?"

The pupils of the engineering department suddenly shrank.

"Your Majesty's words are exactly what you think in your hearts."

The guijian took up the charcoal pen and wrote wildly on the green brick floor: "For example, when the 'floating lamp' is placed in the folk, bamboo strips are soaked in oil and ignite them, and the heat will be carried into the air. If this method is enlarged a hundred times, take a hundred pieces of fire and wash cloth to make a balloon, place a fine iron brazier under it, and burn the green charcoal. Calculate based on the power of the heat rising..."

With the crackling sound of the abacus beads, he suddenly looked up: "If the diameter is five meters, he may bring three armored soldiers to a height of a thousand feet! But it is less than half an hour in the air and is afraid of strong winds."

"Thousands of feet? The height of the Tianyuan of the Chu army is seven thousand feet! You, the "Huoyunzhan", was probably used as a target as soon as you left the ground!" Chen Laojiu sneered: "The fire bag collapses when it encounters rain. What's the difference between it and the kite that ordinary children put on?"

"The difference is that it can be lifted steadily without relying on wind! And it is cheap and can be quickly installed!"

The Armed Forces Academy retorted: "On the other hand, your Lao Shizi Star Array is difficult to find, and the runes are missing. Even if you really get them all together, can you ensure success? I, Daqin, still have time for you to try again and again!"

"you!"

"The "Precious Age" mentions that 'the qi and veins run like the spine of a dragon', and there is also a saying that 'The Xuan Jiao has a wind and thunder sac and breathes in the clouds and clouds three thousand feet'." The youngest record in the Engineering Department suddenly spoke, and he bent down and dripped in tea on the blue bricks:

"If the airbag is changed to a spindle shape, sixteen iron bone support frames can be used as a "Yuncha Flying Ship". Thirty-six air cabins are divided into them, and even if half of them are damaged, they can still be suspended! If the surface of the airbag is coated with thunder beast glue, it can better resist the penetration of arrows! This is based on the watertight cabin of our ship..."

The debate gradually arose.

Yuan Wu stared at the water marks on the brick surface, which was the prototype of the airship in later generations. He flicked his fingers gently, and the tea traces suddenly became three-dimensional and suspended, refracting a colorful halo in the morning light: "How can I defend against the enemy after the cloud raft is formed?"

"Can carry the cloud-chasing crossbow!"

Lao Jijieshi was so excited that his jade crown was astonished: "It is said that when the You Dynasty was in its peak, the 'Sky Eye' was deployed in the floating giant city. Although the specific structure was lost, if forty-nine Changfeng Chasing Crossbows formed the ejection array, it might not be impossible to hit the enemy kite that was seven thousand feet up!"

The craftsman ordered him to take a deep breath and quickly stepped forward: "I see that although the flying kites of the Chu army are profitable, they will consume a lot of money every time they are dispatched. If we use the 'Huoyunzhan' and 'Yuncha Flying Ship' as the basis, we will respond in three steps-"

He unfolded a roll of silk and began to outline: "First, quickly build a thousand five-meter fire cloud cups, carry elite scouts and falcons to the sky, and use their eyesight to limit three thousand feet, which is enough to monitor the movements of the Chu army. Each one consumes eighty pieces of fire-washing cloth and 1,500 kilograms of green charcoal, totaling 90,000 pieces."

"The second is to improve the buoyancy." The Chief Academy of Military Instruments suddenly interrupted: "Si Tian Yaoshu records that the giant ships of the God King of Youchao all use the "clear and turbid wheel rotation method". If a mechanism is opened at the top of the "Yuncha", it will alternately release turbid air and inject clean air, and the duration of stagnation in the air can be extended to three hours!"

The Chief of the Qiguan shook his head: "There are fifteen who are lighter than the normal qi, and the lightest one is the 'Xuan Magnetic Aurora Qi'. However, the preparation method has long been lost. The lightest one is the 'Yang and Qingqi'. The refining requires half of the true energy of a hundred cultivators in the fourth realm every day. The cost of a single ship soars seven times, and they all have to practice the 'Kan and Shake Dissociation Art'. It's better..."

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! He suddenly grabbed the bamboo paper on the desk and folded it into a boat shape, "Imitate the sails of the building boat and the wings of the birds. I installed the "wind sail feathers" on all sides of the "cloud raft", using the wind to boost it to save the clean air inside..."

Everyone's eyes lit up, but Old Chen snorted coldly: "The sails of the building are understandable, but what is the mystery of this 'sail feather'?"

"Birds soar by wings swaying to generate lift. If we install many pairs of foldable huge wings on the 'Yuncha', supplemented by the Xunfeng Talisman array, and control the flapping through the mechanism, we can turn freely like a bird, and even achieve short climbs and dives, greatly improving mobility!"

"When mixing coal with water vapor and smolder, you can also get 'coal gas'... Although this gas is not as good as 'yang and clear air', it can win by volume."

The young recorder added: "If the gas is filled into Yuncha auxiliary airbag, the cost can also be greatly reduced. If it is modified with the "hard oil cabinet" in the army, it can spray flames to boost the flying ship."

"In this way, there are two types of flight ships: long-term air control and short-distance sprint." Yuan Wu nodded slightly: "Continue."

The craftsman made an order to outline it with a charcoal pen: "The third is the technique of ground support... I am on the yin and the moon, the flying spear of the dragon, and the golden crow, and the shooting height can reach more than ten thousand feet, which is far better than the heavy crossbow. Only the problem of precise locking is needed to develop a special guide array for air..."

He stopped writing and took a deep breath: "If these three steps are done, our Daqin can compete with the Chu army Tianyuan, and even counterattack the enemy!"

"...The strange birds and dragons can all fly at a height of four or five thousand feet, and control the air and flow in the sky without any obstacles. If you want to pretend to be the nature of the birds, why not directly tame the birds?"

The Beast Garden Supervisor, who had been silent, suddenly spoke. His fingers filled with dragon scales stroked the mottled beast patterns on the bronze medal on his waist, and his hoarse voice spread in the hall: "Seven years ago, the queen ordered his subordinates to cultivate hybrid alien species of Xuan Scale Eagle and Mingxue Wu. Now he has obtained more than 9,000 heads, weighing 300 kilograms, and his wingspan can reach 42 feet and 2 feet..."

"After testing by Weichen, this bird can carry a weight of 1,000 kilograms to a height of 5,000 feet, and its eyes can penetrate clouds and mists, and more than ten miles away. If it is equipped with a special saddle and chain, it can be controlled by the knights and become a real 'Sky Rider' army! When it is released from the 'Yuncha' mothership, it must be even more..."

"Most? That's because there's no actual test." Yuan Wu frowned and interrupted: "Do you know that on the battlefield, a 'mostly' could ruin the lives of thousands of soldiers?"

"The strange birds and beasts are violent and difficult to tame. If they suddenly go crazy at a high altitude, the knights fall and die. If the Chu people take the opportunity to attack Tianyuan, wouldn't it be a use of a sword? Zheng Wujiu, do you have a solution to ensure that they can obey orders during war?"

"This..." The beast garden supervisor was speechless and sweated coldly on his forehead.

“But this path is also worth exploring.”

Yuan Wu pondered for a moment and waved his hand: "In this way, after you go back, you can select the hundred strange birds with the most docile and domesticated nature, and tell the 3,000 prisoners in Longxi, conduct manned flight tests locally, and report them after success and apply for funds."

"promise!"

"By the way, when the birds you raise fly at a height of five thousand feet, how do you control them to make sure they don't take the opportunity to escape? Just take secret medicine regularly as bait?"

The Armory Academy suddenly noticed this keenly and quickly grabbed the sleeve that the Beast Garden Supervisor wanted to turn: "Is it because of the whistle-like note magic weapon to guide it? The sound can be as far as the air... Yes, the newly developed note arrows may be the nemesis of Chu Yuan and others!"

Everyone present knew that the notes arrow was originally an invention of the Great Chu Dynasty. It aimed to interfere with the flow of true energy and blood in the enemy's body with sound wave oscillation of special frequency, gradually tearing the meridians and blood vessels, causing large-scale killing. Later, the secret was stolen by Qin spies, copied and improved its own version.

"Although Chu Yuan's flight altitude is high, it must be within the range where sound waves can be transmitted. As long as it determines its approximate frequency band, it can try to interfere with or even kill with notes!" The Parliament Academy of Armed Forces became more and more excited as the Parliament Academy spoke, "Your Majesty, if this plan is done, the Chu army Tianyuan will defeat it without attacking!"

"But based on existing observation data, the flying speed of the enemy can completely break through the sound barrier. Before the sound wave of your notes arrow spreads, the opponent has already flew out of the attack range."

Jiang Zuoling immediately raised objections: "And, in high altitudes, the effect of sound transmission will be greatly reduced, and this plan may be difficult to work...or in other words, it can only be used for the construction of ground defense systems, and we must not hope that it will play a role in air combat."

"Can Tianyuan keep the speed of flying swords? Even so, we can use notes to block them up, down, back, left and right, and set up a net of heaven and earth!" The Armory Academy retorted unwillingly: "As long as we calculate the advance amount, notes to still hit the enemy kiln moving at high speed!"

"Besides, under the attachment of a specific vital environment and true energy, the speed of the sound can be greatly improved, which can completely surpass Tianyuan's maneuver! In short, I think this is worth a try!"

"Do you burn the 'Big Road Thunder' array pattern? Do you know how much more cost will be? How difficult is it to integrate into an arrow?"

"Since the Chu army Fei Yuan is driven by mysterious mechanisms, it may be able to try to interfere with its control system with a talisman array. For example, the 'reverse Yuan Magnetic Five Elements Array' can cause all metal objects to point in a certain range to fail... This method is not limited to the speed of sound, it is just..."

"Birds have wings innately, but humans and beasts have no such thing as this. If the air flow rises and falls, we can develop a 'After-Wing' type talisman..."

Amid the waves of debate, Yuan Wu's eyes suddenly looked at the copper bells at the eaves. When the north wind passed by, the hanging silk ribbons stagnated at a certain angle. "Wind." The cyclone condensed at his fingertips shattered three snowflakes, "Since the Chu army is soaring by the airflow, then let the master of the seventh realm disrupt the celestial phenomena."

"Your Majesty is wise!" The old doctor of the observatory trembled with a celestial plate and bamboo slips: "Please see, the celestial phenomena record that the Chu army air strike last night happened to be in chaos in the Xun position. The old minister remembered the East China Sea storm forty years ago. The fishermen saw a dragon absorbing water and connecting the sky to the sea..."

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! "Speak with human words!"

"Verizon!" The old doctor knelt down on the ground: "I have seen half of the mast of the ancient ship in the ancient battlefield of Youshan, and there are spiral grooves at the core! Or you can use the two clear and turbid air to hedge it to form an artificial tornado, and use the power of heaven and earth to tear the Chu army's formation apart! It's like a kite encountering a turbulent flow-"

Mr. Chen offered wine and stroking his beards and sighed: "It also records that in the late You Dynasty, a 'Feng Bo' triggered a hurricane with the power of nine stars and pearls, blowing away tens of millions of rebels within one day and overturning the mountains. If the seven masters were ordered to guard Tianshu and Yaoguang and other star positions..."

"The ability of moving mountains in the seven realms is not only to create wind whirlpools?"

Yuan Wu Surong said: "The cold air alone condenses billions of hail, covering a radius of hundreds of miles, which is enough to make the Chu army Tianyuan have nowhere to hide; if the "Liyang Chisel Array" is supervised on the border, it can also attract star rays, and the Nine Heavens Thunderstorm destroys the airspace..."

"But this method must not be repeated, and it must be done without encountering a dangerous situation. The Chu army also has masters of the seventh realm. If we consume it first, the high-level combat power will be temporarily empty, and we may fall into a huge passive position."

"What I want you to do is to find the most cost-effective solution, rather than pile up your cultivation regardless of cost!"

Silence fell into Zichen Palace again.

All officials understood that Emperor Yuanwu was seeking a tactic that could be applied on a large scale and was relatively low-cost, rather than relying solely on the personal force of the master-level powerful.

...

The ticking sound of the copper leak at the corner of the hall was suddenly cut off by the sword sound bursting from Yuan Wu's sleeve. A half-inch of green light condensed from the emperor's fingertips. Starting from the Eagle Beak Cliff that simulates a sand table in Hangu Pass, a sword mark extending a hundred miles and entering Yangshan County, Chujing: "In three days, I will see the prototype of the Tianjiwei."

"Everyone who has any questions has its own opportunities, so they all need to be promoted simultaneously." The ministers suddenly held their breath, but saw Yuan Wu's sleeves brushing over the tea model suspended on the blue bricks. The illusory spindle-shaped cloud raft first expanded to three feet, and then cracked into seven streams of light:

"From now on, the Tianjiwei will be divided into seven departments - the Huoyun Department will mainly attack hot air aerial vehicles, the Yuncha Department will specialize in researching composite ships, the Tianqin Department will domesticate alien flying cavalry, the Leiyin Department will develop sound wave magnetic wave killing devices, the Earth Anchor Department will be responsible for air talisman equipment, Hurricane Taiwan will specialize in meteorological tactics, and finally set up a gold calculation room to coordinate money and grain."

He bent his fingers and knocked on the table: "The first batch of fire-clothing divisions has allocated 100,000 pieces of fire-clothing cloth and 3 million kilograms of green charcoal. The Industrial and Industrial Department needs to complete a thousand five-meter-level floating cups within ten days; the Yuncha Department has led a hundred oaths of thunder beast glue liquid, and recruited hundreds of monks in the military and horse department to refine Yang and Qingqi in shifts, and filled the air compartment of ten test ships every three days."

"Your Majesty!" The Chief of the Beast Garden suddenly knelt down and took two steps. "If the Tianqin Army wants to form an army in a hundred days, it is necessary to add 50,000 spiritual elixirs, 3,000 dragon bone powder, and 800 beast slaves in Jiaodong County..."

"Accurate. Each alien bird has three kilograms of cold marrow pill to suppress the ferociousness. The prisoner can get half a year of service every test flight." Yuan Wu extended his finger and wrote on the bronze case: "But the list of losses must be submitted every ten days. If more than 70% of the prisoners fell within three months, you can fill the eagle's nest by yourself."

The Parliament of the Military Academy couldn't wait to unfold the scroll: "The Leiyin Department applied to call the 3,000 Xuanyin Yu in the Shaofu stock, and also needed to recruit 12 Yuefu lawyers, as well as all practitioners who know "sound transmission techniques" within 300 miles of southern Xinjiang to set up a nine-tone resonance tower on the top of Yuncha..."

"How much does it cost?" The Chief Supervisor who lowered his head and drew countless drawings suddenly raised his head and interrupted, "According to the diameter of each cloud raft, about fifty meters long, and with three sound towers, the cost of a single ship will exceed 120,000 yuan!"

"Then cut off the Zhenfengfan feathers in Yuncha's part!" The palm courtyard roared with its neck, "Anyway, those iron bone feather wings need to consume thousands of forged steel, so it's better to concentrate resources on..."

"Rareless!" Yuanwu's pressure was like Mount Tai overturning, and the blue bricks under everyone's feet were cracked at the same time. "Yuncha and Leiyin departments each received 1.4 million initial funds, and submitted a detailed list of expenses before the hour of Mao in three days. Jinsuanfang sent twelve red-robed supervisors to various treasury rooms, and those who dared to be greedy for half a piece of copper--"

He also pointed and struck through the void like a sword. The bronze statue of the palace guarding the gate ten feet outside the hall broke its head, and sparks burst into blood at the incision: "This is the end."

Chen Laojiu suddenly raised half of the broken star map: "I dare to ask Your Majesty, the old minister's twenty-eight formation..."
To be continued...
