"How is it... I said that there is still half an hour before I will be in...!" Zhu Lang walked to Zhu Zhen and others and asked with a smile.

"Brother Lang..." Zhu Zhen, Zhu Jing, Zhu Zi, Zhu Tan saw Zhu Lang and hurriedly stood up to salute. In the past two months, Zhu Lang's knowledge has completely convinced these boys, so they respect Zhu Lang very much.

"All up...you guys are getting more and more polite. This is not the case before." Zhu Lang walked among the four with a smile, looked at the hot air balloon on the ground and asked, "How is the mode?"

"Long Ge...it's almost done. Today's weather is good, without wind and clear. I believe there is no problem with flying." Zhu Zhen replied.

"That's good... Remember, everything is mainly about safety, and you can't go up." Zhu Lang looked at Zhu Tan on the side and said, "There is nothing in the sky, you... stop fantasizing."

Zhu Tan nodded: "I know."

"Okay... Dad is coming soon, the prince, King Jin and others will come here too. You guys... Organize and prepare to pick up the car. Zhu Tan will explain the principle of the hot air balloon, so that Dad and Prince can understand it."

"Yes..." After Zhu Lang said that, Zhu Zhen and others immediately bowed, which was really very respectful to Zhu Lang.

After about a stick of incense, Zhu Yuanzhang, Empress Ma, Zhu Biao, Zhu Qi, Zhu Di, Zhu Su and others also came together. Seeing the size of the hot air balloon, Zhu Yuanzhang also exclaimed repeatedly: "Wow... how big would it be if it rose directly?"

"But how can this rise?" Queen Ma also showed an incredible expression.

"It's really too big. Queen Mother, this skin is made of whale skin. I've eaten the whale meat queen. Has the whale mother seen it? I heard it's as big as a hill." Zhu Biao said he hehe.

"It's as big as a hill, and it's true or false. Your elder brother won't cheat on his mother, right?" Queen Ma looked at her third son.

"It's true, Mother Queen, I heard from those whaling people that it's really as big as a hill. My son will go out to sea soon. If you encounter whales, my son will catch the largest one and send it to my mother... Let the mother Queen take a look." Zhu Qi said with a chuckling.

"Okay...then I am waiting for the whale inside...!" After saying that, Queen Ma smiled happily.

Zhu Biao and Zhu Qi burst into laughter, only Zhu Di's face became a little colder. At this time, Zhu Tan stood up and said, "Father, Queen, let me tell you about the working principle of this hot air balloon."

"Oh... Tan'er said, then the father must listen carefully. The father has heard that Tan'er has been very well-behaved during this period. He has not been with the Taoist priests and has been staying in the palace peacefully. Your mother also doesn't know how many times she praised in front of us. It's Tan'er who studied hard.

Then let’s listen to Tan’er’s introduction to us and your mother.” Zhu Yuanzhang looked at Zhu Tan with a smile, and no longer had the contemptuous expression he used to be.

Queen Ma also nodded repeatedly: "Tan'er is really good. Her monthly salary will increase by another 100 taels in the future. I will study hard with you, Lang Ge. The queen mother is optimistic about you."

"Thank you, my father, my mother..." Zhu Tan was very happy.

Then Zhu Tan took Zhu Yuanzhang and Empress Ma to introduce the hot air balloon: "Father, mother, Kongming Lantern is an aircraft invented in ancient times. Its principle was first recorded in "Huainan Wanbishu": "Aihuo makes chickens fly."

That is to say, putting the burning mugwort into the egg shell can make the egg shell fly. In fact, this is the same as the principle of a hot air balloon. The density of hot air generated by the combustion of mugwort is lower than that of the external air, and the buoyancy generated on the egg shell is greater than the gravity, so it can be lifted off.

Initially, people used wax paper to make Kongming lanterns. Wax paper has the characteristics of flame retardant and rainproof, and hot air is not easy to flow out of the wax paper. Once the fuel placed in it is ignited, the generated hot air can be lifted out of the air.

Later, our Ming Dynasty Kongming lanterns made lampshades with more advanced safety flame retardant cotton paper or thickened flame retardant copy paper. The Kongming lanterns made in this way are less likely to burn. Most of the fuel used in Kongming lanterns are wax blocks, and they can also be specially customized cotton fuel with greater firepower.

Because of this Kongming lantern, Erchen thought of the hot air balloon. Can a large manned Kongming lantern fly up again? Later, Lang Ge began to guide us. This time we invented this hot air balloon. The kinetic energy of this hot air balloon is smoke...!"

"Yan..." Zhu Yuanzhang and others were a little surprised.

Zhu Tan nodded and smiled, "When an object is burned, thick smoke will appear, and clothes roasted on the fire can be lifted up by the heat emitted by the fire, which inspired the idea of ​​hot air balloons."

"Oh...so that's how it is..." Everyone understood.

Just like that... the performance time is coming, and Zhu Yuanzhang and others have returned to their own positions. At this time, it should be ten o'clock in the morning. There are about 100,000 people coming to Qiuxin Lake Town today to see Feitian.

After everything is ready, the first flight of the hot air balloon is about to begin.

However, this first time the hot air balloon was flying, the raw materials in it were not flames or hot air, but real black smoke, Zhu Zhen, Zhu Jun, Zhu Zi, Zhu Tan... burning straws crazy under the hot air balloon, so that the hot air balloon can take off.

Because according to Zhu Lang's mobile phone, these thick smoke help the balloon take off. In order to increase the thick smoke, they also specially added some wet cloth and carrion to the straw, which can increase the burning time and increase the output of thick smoke.

Outside the field, I saw a large stream of thick smoke rushing into the hot air balloon, and soon supported the huge balloon, which slowly supported it at a speed visible to the naked eye.

There was a horrifying voice outside the field: "Look, the big ball has been charged, it seems that it is really about to fly!"

As soon as this was said, Zhu Yuanzhang, Empress Ma, Zhu Biao and others also held their breath together and watched the hot air balloons so nervously. Sure enough, the hot air balloon slowly floated up, and there was a puppy in the hanging basket of the hot air balloon.

"Flying up..." Seeing that the hot air balloon successfully broke away from the ground and slowly flew into the sky, Zhu Zhen, Zhu Tan, Zhu Jun, Zhu Zi and others hugged each other happily. The hot air balloon rose by a total of 800 meters, and then flew for eight minutes, about 2,000 meters, and then slowly fell down. They brought the puppy back with the people who had passed. The puppy was not damaged at all.

The applause rang like this. The four people Zhu Zhen, Zhu Tan, Zhu Jing and Zhu Zi, who were still excited, suddenly burst into tears in surprise for some reason after hearing the applause. Tears couldn't resist it. Finally, the four of them held a student ceremony to Zhu Lang together, which was sincere.

Zhu Yuanzhang and Empress Ma also applauded and immediately gave rewards. Zhu Yuanzhang also asked the four people to continue researching and the palace could allocate wages, hoping that the four people could make hot air balloons that could carry people as soon as possible. After Zhu Yuanzhang's encouragement, the four people were also excited.

Maybe Zhu Lang himself did not expect that soon the earliest air force of the Ming Dynasty would appear. To talk about the real air force of China, the origin of the late Qing Dynasty, was the first to be equipped with reconnaissance hot air balloons.

In the Sino-French War that broke out in 1884, France took the lead in using balloons on the Vietnam battlefield for aerial reconnaissance. In 1904, the Russo-Japanese War kicked off in Northeast China. The Japanese army used two balloons to form a temporary balloon team, which made great contributions to the capture of Lushun, which was defending the Russian army.

These two battles made the air weapon Balloon, a powerful aviation weapon, debut in front of the Chinese, attracting the high attention of the Qing government.

With the spread of the balloon theory in China, the test flight of the hydrogen balloon that the Chinese invented was successful, and the Qing government came up with the idea of ​​forming a balloon team.

In 1905, Zhang Zhidong, the former representative of the Westernization Party and the governor of Huguang (1837-1909), purchased two "Yamada"-style balloons from Japan for the first time.

This type of balloon is tethered, with an oval shape, with a horizontal diameter of about 4 meters and a length of about 25 meters, and is filled with hydrogen. The balloon has a rudder cloth, which can be adjusted in the air; there is a winch on the ground, and the height of the balloon hanging in the air is controlled by cables and the balloon is collected and released; there is a rattan basket under the balloon. People use a telescope to observe the ground in the basket, and can report the observed situation to the ground with flags or telephones, which is convenient for command; it is also equipped with photography equipment, which can conduct aerial photography reconnaissance.

At that time, Japanese technicians were hired to coach Chinese soldiers to use balloons.

In February 1908, the Eighth Town of Hubei Army was first equipped with a Yamada-style balloon, and established the Eighth Town Balloon Team of the Army, with Wang Yongquan, the Engineering Battalion Management Leader, as the captain; in May, the Jiangsu Army, the Ninth Town Balloon Team was established, with one Yamada-style balloon, and Deng Zhiyi, the Engineering Battalion Management Leader, as the captain; in June, the Fourth Town Balloon Team of the Zhili Army, was established, with one Yamada-style balloon, and Gao Ningchen, the Engineering Battalion Management Leader, as the captain.

In October 1908, during the Qing army's autumn exercises (exercise) in Taihu Lake, Anhui, the eighth and ninth town balloon teams participated in the exercise. This was the beginning of the modern Chinese army's use of aircraft.

In early 1911, in the Yongping Qiucao plan formulated by the Qing government's Army Department, Wang Yongquan, the Eighth Town Engineering Battalion of the Army, took two balloons to participate. It can be seen that the balloon team had been included in the army sequence. At that time, the balloon team participated in major military exercises, which shows that the Qing army attached great importance to the balloon team.

The balloon team set up by the late Qing government is the prototype of our air force. Although there are no more than five balloons equipped, as a new type of air armed forces, the birth of the balloon team in the late Qing Dynasty marked the birth of our air force. Unfortunately, the balloon team in the late Qing Dynasty only made a brilliant debut in several military exercises and was not actually used in wars. Therefore, to a certain extent, the balloon team in the late Qing Dynasty only had the nature of an air force honor guard.

Fortunately, this time it was different. The four princes, Zhu Zhen, Zhu Tan, Zhu Jing and Zhu Zi, were recognized by their father and devoted themselves to the development of hot air balloons. They wanted to complete the hot air balloon manned as soon as possible.

This is still the early Ming Dynasty. As long as there is such a spirit, it is not a dream for the Ming Dynasty to have its own air force.

....................................

"Please let me go, I will definitely not say anything. If I go out and say something, I will be so sad... You have already taken one leg of me, why do you still kill me?" In a broken house in Yingtian Mansion, a lame man begged desperately.

But the other party had no sympathy: "You must die if you die, and don't make any vows, because such vows are useless. The only thing we believe is that the dead will not speak.

You have lost one leg, can you give me a life now?"

As he said that, the man in black stepped forward and a terrifying smile appeared on the corner of his mouth.

"You...you are really inferior to beasts. You deceived our brothers into coming to Yingtian Mansion and treated us like this afterwards. If my brother knew that you treated me like this, he would definitely expose you." The man looked at the man in black in fear.

"Haha..." The man in black laughed: "You are so beautiful. Actually, what I want to tell you is that when you and your brother draw lots, your brother tampered with each other. Only you still foolishly thought it was God's will.

In fact, your brother also asked you to die sooner. Now your brother is the spokesperson of miracles. How many people invite him to the mansion to eat and drink, look at his legs. You are so stupid.

I was stupid enough to think your brother would help you, but in fact your brother is the one who wants you to die the most, because if you die, he is the only real one."

"What...!" The man was stunned, and when he was stunned, the man was strangled with his hands and helped the pillar. A bucket of turmeric oil poured from his head. He ignited it, and the fire instantly burned the man's body. The man wanted to make a tragic roar, but he suddenly realized that he could not make any sound.

The fire burned quickly with the help of tinea oil. After a while, the man turned into ashes. The more miserable it would be, the more miserable it would be. However, this group of people were secretly secreted and thought that after burning the man to death, it would be all over.

But they underestimated a new coroner from Dali Temple. Soon the incident of a lame man being burned to ashes spread in Dali Temple. Of course, this incident has not yet attracted Zhu Lang's attention.

Zhu Lang was preparing for his trip to Shandong. Zhu Jian, Zhu Di, Zhu Qi... There are other lucky ship captains who have all obtained larger treasure ships, but the Flang machine cannons on the treasure ships have caused everyone to fight for.

Ten treasure ships, one of which is a flagship, is set to thirty of the Flanger cannons on the flagship. In this way, the remaining seventy Flanger cannons must be divided by nine treasure ships. No one is willing to take fewer cannons, and he is even more unwilling to have their own treasure ship not the flagship.

So during this period, Zhu Lang's home was very lively. Not only the ten treasure ship captains, but the captains of these treasure ships showed their magical powers and used all the resources they could use.

It is just for himself to get the flagship, for the sake of artillery and flagship, the captains of these treasure ships have gone completely crazy, and even Zhu Di has completely fallen.
