From the Nine Eyes Bridge to the East City Gate, the square land has now become a hell on earth.

Li Chengdong was cruel. The person who went up died and immediately ordered someone to continue, without any intention of stopping.

The Ming army on the top of the city had to shoot against the Qing soldiers' archers on the one hand, and on the other hand, they had to shoot the Qing soldiers who were unconscious. The most important thing was to shoot the Qing soldiers who were unconscious.

After an hour, the Qing soldiers left nearly a thousand bodies, and the Ming army also suffered 300 casualties.

The casualties ratio of one to three is still a cheaper place for the advantage of the location and the three Franco cannons, which is not a proud record in any case.

The method of using water to flush the soil was stopped, and it did not work at all. It just turned the outside of the East City Gate into a muddy place.

"No, you must think of another way." Zhu Youlang looked at the rising earth road outside the city, feeling anxious.

The Qing soldiers attacked the city with such a desperate situation, and the results were very obvious. They were about ten feet high near the highest point of the city wall. At this speed, they could fill in another two thousand lives, and probably a horse road would be able to make it.

By then, Zhang Hu's 1,000 people should have been wiped out. After yesterday and today's war baptism, these soldiers have lost their youthfulness and tenderness, and have gradually become mature and sophisticated. Such a team has been preserved, but a precious wealth, Zhu Youlang is reluctant to let these people die.

"What should I do? The cannons that caused huge damage to the Qing soldiers were red, and they could only be reused after they were cooled down naturally. In this way, our army's firepower would be greatly reduced. The process of the Qing soldiers paving the city will be greatly accelerated. The situation is critical." Zhu Youlang looked at the three already dumb cannons and his mind was spinning rapidly.

"Archite? Firearm? Yes, Firearm!" Suddenly, a flash of inspiration flashed in my mind, and I was overjoyed: "If you can't make other firearms, can you still not make a few land mines?"

"Jisheng, are there any military weapon camps or military battles in the city?" Zhu Youlang hurriedly called Chen Zizhuang and asked.

The military weapon battalion is affiliated to the Ministry of Industry and is specifically responsible for the manufacturing of weapons, while the Military War Bureau is affiliated to the Inner Palace, which is collectively known as the Mingjiu Bureau, along with the Silver Bureau, the Washing Clothes Bureau, the Scarf and Hat Bureau, the Needle Industry Bureau, the Inner Weaving and Dyeing Bureau, the Wine and Vinegar and the Siyuan Bureau.

"Return to the emperor, the puppet dynasty was established in a rarity, and there was no military battle situation. There were military weapons barracks, so they could only build and repair weapons." Chen Zizhuang replied.

"Where is gunpowder? Where is gunpowder?" Zhu Youlang asked again.

"There are military weapons battalions."

"Okay, send someone to find the craftsmen of the military weapon barracks immediately, the faster the better."

"Abide by the order!"

Chen Zizhuang agreed and hurriedly directed people to find them.

Zhu Youlang asked Chen Bangyan to come again and asked him to send someone to find some jars and jars.

...

Chen Zizhuang quickly found two people, and Chen Bangyan quickly found a porcelain shop and brought in all their inventory.

Two military weapon craftsmen were named Yao Desan and the other was named Zhang Nianbao.

Yao De is in his thirties and forties, with gray hair, deep wrinkles on his face, and rough skin on his hands. You can tell at first sight that life is not easy.

Zhang Nianbao was in his thirties, short and strong, with a confused look on his face. What’s ridiculous is that his face and hands were dark, just like gunpowder.

In fact, Yao Desan is a weapon casting craftsman, while Zhang Nianbao is a military weapon camp gunpowder warehouse craftsman.

"The villain kowtows to the emperor!" Yao Desan saw Zhu Youlang and kowtowed quickly. Zhang Nianbao followed behind and followed suit.

Yao Desan kowtowed and lay on the ground and stopped moving. However, Zhang Nianbao kept kowtowing, shouting in a low voice: "The villain kowtows to the emperor."

The sound of killing on the top of the city was shocking, and the tension was strong for a while. Zhu Youlang was not interested in treating the qi with these two guys, and hurriedly said, "Don't kowtow, get up quickly, I have something to leave to you."

When he heard the emperor's words, Yao Desan and Zhang Nianbao stood up quickly.

"I want you to build some mines right away. Look," Zhu Youlang took a jar and said to the two of them: "It's like this jar filled with gunpowder, made porcelain, sealed the mouth, and connected the lead..."

"Your Majesty, are you talking about bombings?" Before Zhu Youlang finished speaking, Zhang Nianbao rushed to say.

"Blasting cannon? Have you seen this thing?" Zhu Youlang did not blame him for being rude.

"I heard from my grandfather that my grandfather worked as a soldier under Qi Jiguang and Grandpa Qi. I heard that Grandpa Qi invented a steel wheel ignition bomb at that time." When it comes to bombing, Zhang Nianbao was no longer confused, with bright eyes.

"Oh? You can tell me in detail."

"According to my grandfather, the bomb was made of pig iron, and the medicine was made of empty stomach, and the medicine was placed in a small bamboo tube, and the fire line was penetrated inside and the fire trough was used to pass through the fire trough. The enemy must go to the pit for dozens of consecutive days. The medicine trough was connected to the steel wheel. When the enemy stepped on the motive cable, the steel wheel rotated and rubbed violently with the flint and became angry, which detonated the bomb. I heard that the iron block flew across and injured countless enemies." Zhang Nianbao said.

"Really and false? There were landmines in Qi Jiguang's era? Then why wasn't it used for war on a large scale?" Zhu Youlang was stunned when he heard it. However, he couldn't help but believe what Zhang Nianbao said.

"Can you make it?" Zhu Youlang asked hurriedly.

"Master, someone can make a pig iron shell, and gunpowder is ready-made. However, as the villain listens, the lead wire seems to be very important, and it is difficult to ignite it." Yao Desan replied.

He had a good relationship with Zhang Nianbao, and was afraid that he would talk nonsense again, so he quickly put the words into his head.

"Okay! Yao Desan, go back immediately and gather people to cast cast iron shells. It's about the size, just like this jar." Zhu Youlang glanced at him and found a small jar, and showed it to Yao Desan, and then pointed at Chen Bangyan: "If you want money, you want people to give it to him, please ask Lord Chen for it, you can go down first."

Yao Desan agreed and followed Chen Bangyan's people and hurried down to the city.

"Zhang Nianbao, the Qing soldiers are now very tight to attack the city. We don't have time to use pig iron. We can use these jars first, and install iron nails and stones inside. We can still kill people. However, my request is to light the lead wire and throw it down from the city. Yao Desan said just now. The lead wire is very important. If it is long, it will fall to the ground before it explodes. Once the jar is broken, it will lose its power. It is not enough. If it is short, it will be too lethal. If it is too late, it will be too lethal and it will easily hurt itself. You should think of a solution to this matter. It is best to explode when it falls to the ground." Zhu Youlang ordered.

"Yes, the prince, the villain knows." Zhang Nianbao said.

The guy frowned and thought for a moment, picked up a jar and ran to the side of the city walls and walls. He looked down, threw the jar in his hand, and counted in his mouth: "One breath, two breaths, three breaths..."

Zhang Nianbao was determined to calculate the time and completely forgot about the Qing soldiers under the city. He saw an arrow roaring towards him.

"Protect him quickly!" Zhu Youlang realized his next move when he was running to the wall. He was so anxious that he shouted at Bai Xing. Bai Xing snatched a big shield and ran over to protect Zhang Nianbao.
