(I apologize for pasting the wrong content yesterday, and I will give a thousand words to my book friends today)

"Boom!" "Boom!" "Boom!" The second day of the twelfth lunar month had just dawned, and with the roar of artillery, the final siege of the city of Delhi officially began.

In order to capture the city of Delhi as soon as possible, Lan Zhen, Zhu Shangbing and others also stayed behind. Not a single artillery piece was left in the Bengal area, and they were all pulled to the city of Delhi; Shang Bing and others would not stay on the north bank of the Langqin Zangbo River.

Any artillery. The two armies from the north and the south brought nearly 400 artillery pieces, regardless of size, all lined up in front of the formation, and fired cannonballs at the top of the city!

"General Lan, it is really a waste to let four hundred artillery fire at the same time." Shang Bing frowned and said to Lan Zhen: "Although the Delhi Sultanate is also a big country in India, it can't be compared with the Ming Dynasty. There isn't much in the first place.

Artillery, not to mention the many lost gates in Bengal, there is no need to bombard the city of Delhi with so many big artillery."

"And if you use artillery like this, it won't take long for the barrel to overheat. All the artillery will have to stop firing, and the firepower of the siege will disappear all of a sudden. Are you going to have to use bows and arrows to support the soldiers who are attacking the city?"

"Your Highness, you won't let all the artillery fire all the time. After a while, 66% of the artillery will stop firing, and then take turns to fire." Lan Zhen replied with a smile: "And the reason for having all the artillery fire at the same time at the beginning of the siege is

Scare the Indians in the city. If you can scare them, maybe you can capture the city of Delhi at once. Wouldn't it be a good thing?"

"So that's what you had in mind, haha! But of course Yinlu was frightened, but the city of Delhi cannot be defeated so easily." Zhu Gui, standing aside, laughed.

"That's okay. It's just to use more cannonballs. It's not easy to transport these cannonballs all the way here anyway. Don't you still want to transport them back? It's okay to use them all!" Lan Zhen said again.

"Okay, let me tell you, why are you so generous? It turned out to be the idea of ​​using the artillery shells we brought." Zhu Gui said with a smile.

"I think General Lan is right. When you return to the northwest from India and there is no big river connecting it, it will be difficult for you to bring the artillery back. It is absolutely impossible to transport these artillery shells back. It is better to shoot them all in Delhi.

Yeah!" Zhu Shangbing joked.

"Shang Bing, which side are you from? Aren't you also the vassal king in the northwest? These cannonballs are shipped back, don't you have a share? And you can definitely recruit Tianfang believers or Brahman believers to transport them, without giving them wages or extra capture.

Just give me two meals." Zhu Gui said.

"You can talk about this little thing for a long time." Zhu Ji interrupted at this time: "Uncle Wang, don't disturb General Lan's command. Since we have agreed to attack the city today and the soldiers have begun to charge, we must

Try your best, Uncle Wang, but we cannot delay the victory of this battle because of you."

"Yes, Uncle Wang,..." Others also offered words of advice.

Seeing this, Zhu Gui curled his lips, but said nothing more. He raised his clairvoyance and looked towards the city. Everyone also raised their clairvoyance to observe the battle situation.

…

…

Lan Zhen's guess was right. The Indians were stunned by the artillery fire. Even after being reminded by the officers, they were prepared for the fierce firepower of the Ming army, but nearly four hundred artillery pieces of various sizes were bombarded at the same time.

It far exceeded their imagination. Countless people shouted "Hell, Hell" in horror and ran away, completely forgetting the existence of the war team. Especially when the fastest-firing shells hit the city wall.

, after killing dozens of soldiers, the panic reached the extreme. Not only the ordinary soldiers, but also the officers and supervisors were so frightened that they wanted to flee down the city. At this time, the Ming army had already rushed to the city, which was only more than 200 steps away.

In this place, the leading Qianbai households were very happy when they saw the Indian soldiers on the city wall in such a panic, thinking that this battle would be won so easily.

At the critical moment, Said's guards rushed up and shot hundreds of people to stop the panic at the top of the city. Of course, Said had never seen such a violent bombardment, and he was stunned for a moment. But

He quickly came to his senses, saw the chaos at the top of the city, and immediately ordered the guards to rush forward to restore order. Under the deterrent force of the guards, the soldiers did not dare to escape anymore, and the officers hurriedly reorganized the army.

Resist the Ming army's attack.

But at this time, the Ming army had already rushed to the bottom of the city. Countless ladders were erected, and many people climbed up using the pits and pits left by the shells on the city wall.

The Indian soldiers hurriedly pushed down the ladders and threw rolling rocks down. Many Ming soldiers fell to the ground and screamed, but more Ming soldiers rushed over, and the crossbowmen raised their crossbows to shoot arrows at the top of the city to cover the city.

The infantry attacked the city. The Indian archers also immediately returned fire.

At this time, the volley of four hundred artillery pieces had ended, and only 33% of the artillery pieces were still bombarding. But even so, such artillery fire still greatly supported the infantry siege. From time to time, soldiers on the top of the city were hit by artillery shells and became

Meat pie, or a dent in the body and head; and several shells hit the iron pot filled with hot water or gold juice, the boiling water splashed everywhere, and the surrounding soldiers screamed and fled away. Although the soldiers were pressed by the officers,

He did not dare to escape under the intimidation of his subordinates and the supervising team, but he was still very afraid and guarded against the Ming army's attack tremblingly.

Seeing this situation, Said had to use artillery in advance. He originally didn't want to use artillery so early, but the Ming army's artillery was too many, and it hit a city wall. If the artillery was not used, I am afraid that the Ming army would attack today.

Going to the top of the city, Said could only tell the guards: "Send the order and use the artillery from the south to bombard the Ming army's artillery position."

"Sultan, the artillery position of the Ming army is far away from the city wall. Although their artillery can hit the city of Delhi, our artillery does not have enough range. I am afraid that it cannot hit the Ming army's artillery."

"If you can't shoot big cannons, you can just shoot a few small cannons. Two-thirds of the Ming army's 400 cannons are small and medium-sized artillery. Destroying these can also reduce the pressure on the city."

"Sultan," the guard wanted to argue, but Said sternly said: "Go and convey my order!"

"Yes, Sultan." The guard did not dare to say anything more and immediately ran out of the room to convey the order. After a while, the few remaining artillery pieces were pushed out, loaded with gunpowder and shells, and bombarded the Ming army's artillery position.

Seeing artillery shells passing through the air and landing near his own artillery, Song, who was in charge of the artillery, immediately realized that the Indian artillery had begun to counterattack. He ordered the artillery with a long range to continue bombarding the city, but the artillery with a shorter range dispersed.

Come. But just as he ordered to go down, one of Lan Zhen's guards galloped over on horseback and said to him: "General Song, General Lan ordered not to disperse the artillery, but still concentrate on bombarding the city head!"

Song instantly guessed what Lan Zhen was thinking. "General Lan wants to fight with the Yinluo's artillery on the city wall and knock out the Yinluo's artillery?"

"What General Song said is true. This is exactly what General Lan meant." The guard said: "It is expected that the Yinlu still have artillery, but there must not be many. If the artillery is concentrated to bombard the place where the Yinlu's artillery is, so

Multiple artillery pieces will surely destroy the Yinlu’s artillery pieces!”

"General Lan is courageous. Even though I thought of this, I didn't dare to give this order." Song said to himself. He then raised his voice: "Adjust the muzzle and bombard the place where the white smoke is coming from the city wall." All the gunners hurriedly adjusted.

At the muzzle of the cannon, he didn't care even if the Yinlu's cannonballs fell next to him. He then loaded the gunpowder shells and bombarded the city. Song noticed that the guards who came to deliver the order did not leave. He was a little confused, but he didn't care. He just directed the artillery.

But after two more rounds of bombardment, I saw white smoke floating everywhere on the city wall. The entire city was covered. I could only hear the roar of the artillery, but I couldn't tell where the artillery was.

Song did not order to stop the bombardment, but he became anxious in his heart. When he looked at it with clairvoyance at first, Yinlu's artillery was completely invisible, so it could be moved. If he couldn't see where Yinlu's artillery was, he could fire at the top of the city at will.

, if you want to knock out the Yinlu's artillery, you can only rely on Buddha, Taoist or God to side with the Ming army, and their magic power is higher than that of the gods of Tianfang believers.

He was getting anxious when the guard who had not left suddenly leaned a foot away from him and said: "General Song, are you anxious because you don't know where the Yinlu artillery on top of the city is?"

"This is true, General. How come you can see Yinlu's artillery?" Song said angrily. He was annoyed. If the person who spoke was not Lan Zhen's guard, he would definitely get twenty lashes.

Song's guards also looked at the talkative man with a joking look, to see how he would answer. But to everyone's expectation, the guard said: "General Song, I really can't see where the artillery at the top of the city is.

But the lower official can figure it out."

"Calculate it? Do you know the art of divination?" Song asked in surprise. He then remembered the identity of the person in front of him: Lan Zhen's guard. Lan Zhen has always been strict with the guards around her and would never dare to mess around in front of him.

Talk; he then remembered that this man did not leave after passing the military order just now. Apparently Lan Zhen expected that Yinlu would use this method to cover up the location of his army's artillery, and sent him over to crack Yinlu's method. But Song still had a little more

Doubtful. 'The art of divination is supposed to calculate big things, but can it also calculate small things like the location of artillery?'

"No, General Song, I don't know how to do divination. I use mathematics to calculate the location of the artillery." the guard replied.

"math?"

"Yes, General Song. Although Fu lags behind the Ming Dynasty in most aspects, there is a school of mathematics that is unique and cannot be matched by the Ming Dynasty. This school is clearly geometry. Using geometry, you can calculate where the Yinlu's artillery is.

Not only the position of the artillery, but also the position of the moon and stars can be calculated using geometry. The sixth son of the emperor studied astronomy, and what he is studying now is geometry."

"Can you calculate it using mathematics? You can do the math and let me see." Song was very curious and signaled the small and medium-sized artillery to stop bombarding the city, and then began to watch the process of him calculating the position of the artillery.

The guard first bowed to Song, then took out many tools from his horse and started making gestures, which Song couldn't understand. After making gestures for a while, the guard took out a pen and paper and a plywood from his bag and sat on the stone.

Then he started writing and drawing. Song stretched his head and saw that it read: "Let the horizontal displacement be x, the vertical displacement be y, the horizontal speed be vx0, the vertical speed be vy, the initial speed vy0, and the resultant speed be

v, the launch elevation angle is a, the gravity acceleration is g, and the time is t. Then x=vx0*t, vy = vy0-g*t.…”

Song Cai felt dizzy after just one glance and had to pull his head back. It took him a lot of perseverance to resist saying "What the hell is this?" and stood aside waiting for the guard's calculation results. If according to his

The calculation results showed that bombardment could not knock out even one of Yinlu's artillery. He must give advice to His Majesty and stop studying such useless things.

The guard calculated for a while. During this period, one of the artillery was hit and damaged by the Yinlu's artillery shell. Another artillery shell fell next to the artillery, killing two gunners. However, Song still did not order the artillery to counterattack.

"General Song, the Indian artillery is there now, about five feet deep from the outer city wall. Although you can't see the city head clearly now, the distance from here to the south wall of Delhi City should have been measured. Even if you can't see the city head clearly, you can still bombard it.

Get to the right place." The guard calculated the position and pointed to a place at the top of the city and said to Song. "Yinlu's artillery changes position every half an hour. It has been three-quarters of an hour since it changed to its current position. Please ask General Song to bombard it immediately.

.”

"All artillery, bombard that position." Song ordered. Soon, all the artillery turned their muzzles to bombard the place pointed out by the guard.

"General, do you think he can calculate the position of the artillery?" A commander came over and whispered in Song's ear.

"No matter whether he can calculate it or not, he must give General Lan a face and try bombing it once. If he calculates it wrong, I will definitely advise His Majesty and no longer let people study these useless things."

"How is it possible to calculate the position of the artillery?" the commander smiled. Song also smiled, but said nothing more.

The white smoke filled the air, and of course they couldn't see what was happening at the top of the city of Delhi. But after a while, Song suddenly realized that there seemed to be fewer incoming shells.

‘Is it true that there are Yinlu’s artillery somewhere? Is this person really accurate?’ He couldn’t help but look at Lan Zhen’s guard who was calculating the position.

'No, even if there is indeed a Yinlu cannon at the position he pointed to, it may not be that he has calculated it accurately, it may just be a coincidence. But if he can really calculate it accurately, then this geometry will be very useful. I will explain it in a while

Go and tell Lan Zhen not to massacre the captured Indian soldiers. After the capture of Delhi, I will send someone to interrogate the prisoners and ask if he is really accurate.' Lan Zhen thought.

"We changed places twice in a row, and were discovered by the Ming army and bombarded with artillery?" Said asked the person in front of him in surprise.

"Sultan, it's true. Just half an hour ago, the Ming army didn't know whether they guessed it or something. They suddenly concentrated on bombarding the place where our artillery was. Two artillery pieces in a row were destroyed. They hurriedly ordered the soldiers to move to the place, but after that

Less than a quarter of an hour later, he was discovered again by the Ming army, and a quarter of an hour later he was discovered again after moving to another location." The artillery officer in front of Said was also very surprised.

"Even if there are spies, how can the location be transmitted when the fog is thick? But after careful inspection, is there anyone using smoke or light to look like they are transmitting a message?" Said asked.

"Sultan, after the location was discovered twice in a row, the supervising team also checked it very carefully, but no one disobeyed the order and used smoke or light to convey the message." The artillery officer said.

"It's so strange. Then, when you go back, tell Noureddin to keep firing, but change the position every twelve minutes." Said still couldn't understand and didn't want to think about it anymore, so he ordered. The artillery officer agreed and said,

Order to retreat.

"In this way, although the artillery will not be destroyed again, the threat to the Ming army's artillery positions below the city is greatly reduced, and the Ming army can more support the infantry at the top of the city. Fortunately, the city is filled with smoke, and the Ming army's artillery does not know
