Compared with the Chu army artillery, these pig iron cannons are made of thick and heavy, with an inner diameter of only 12 kilograms, but the weight of 32 kilograms. The weight of the cannon means that the wall of the chamber is thick, but the excess sulfur content in pig iron makes it useless no matter how thick the barrel is. This is a cannon barrel made by Juti Mansion several tests. It has a very short lifespan and is very easy to explode.

The Qin army suddenly got the artillery and only conducted a few test shots during the transaction. After that, except for a few left in the Shaofu for sample copying, the other thirty pieces were transferred into Wang Jian's army, and ten of them were dragged by a horse to Linzi. The artillery was a major weapon of the country, and this transfer was only an assistance. The artillery did not belong to Wang Jian's command but was directly under the Shaofu. The general who commanded this army was an unknown person, Tu Sui.

When Wu Fen met with Wang Ben and others, Tu Sui's subordinate Zhong Dan had already placed the cannons one and a half miles away from Shenmen. He chose this position because he was worried about the catapults in the city. He was obviously worried about it. The Qi people in the royal city were in a panic. Their only move was to block the doorway under Tian Yang's command until everything was ready to fire the cannon, and no stone was thrown out in the city.

"Report to sir, great craftsman, witchcraft can be shot." Zhong Gan reported to Wu Ji and Ye Tong who stepped forward. Previously, Aristotle IV's detailed observation of the artillery of the Chu army accumulated first-hand information. During the transaction between the two countries, he and the Mo family craftsmen accepted the test shooting together. Now he is in Wang Jian's army, Wu Ji and Ye Tong followed Zhong Gan to the city of Linzi.

"The medicine is behind, and the bullet is ahead?" Wu Ji asked the most basic question, which is the most likely problem for beginners.

"Of course." Zhong Dan nodded. Without waiting for Wu Ji to ask, he said, "The rest of the matter is based on what the master and great craftsman said."

When the artillery was obtained, Aristotle IV and the Mohist craftsmen negotiated and formulated several guidelines. At that time, the artillery was also exploded, but it was basically considered to be a mistake in operation. Zhong Dan came to ask for instructions, and Wu Ji looked at Ye Tun, who was coughing, and Wu Ji said, "Shoot first."

"Wei." Wu Ji did not mention the test firing, but the concept of the test firing is easy to understand. The trencher also needs to be tested for large-scale projections. Unfortunately, these artillery mounts are completely welded to death and cannot fine-tune the firing angle on the artillery mounts.

"Shoot one!" Zhong Dan ordered the gun craftsman in front.

"The lieutenant has his life, shoot one!" the military officer shouted at one of the cannons. The long-distance raid did not exhaust the gunners, and they were about to bombard the King of Qi with guns, which excited the workers and gunners.

"Shoot--!" The older worker dragged his tone, and after ignition, the dazzling flame flashed at the fire door, and thick ash smoke came out. With a "boom", the double-loaded medicine bag exploded in a rapid fire. While the gunbore was added to a few tiny cracks, the shell was pushed out by the gunpowder gas.

"Witchcraft?!" The shell seemed to hit Zhu Fen, and he was startled. He never knew that the Qin army also had witchcraft.

The same cannon sounded also shocked the Qi soldiers on the top of the city. Their perception and fear of artillery were no less than that of the Qin people. The Qin army actually had artillery that only the Chu people had. How could this city be defended? The doctor who was lamenting in the court shook his whole body when he heard the sound. The moment before, he heard that the Qin people had artillery on Xunwen. In a blink of an eye, it became a reality, and the cannon sounded outside the royal city.

"This is the Chu people who want to destroy our Qi State!" Tian Xuan, the doctor of Pingyuan Jun, knelt down and bowed to the throne, "I ask the king to apologize to Qin to save the country."

"Great misunderstanding!" Tian Xuan proposed to surrender at this time, which immediately attracted the opposition of other doctors. Tian Qi, who had always been close to Qin and Chu, shouted loudly. "The Qin people are not Chu people, and the king apologized for Qin, how can the country survive?! Our cities and towns have become counties and counties of Qin!"

The country is empty, and the city is real. Tian Qi said just this and the doctors present nodded repeatedly, and everyone had the momentum to fight to the end with the Qin people.

"The Qin people came from afar, and they were still in a hurry. Our army had arrived at Pingling yesterday, a hundred and fifty miles away from Linzi." Anping Juntian said. "We will stick to these two or three days, and we will definitely be able to..."

"Quickly block the doorway! Quickly block the doorway..." Doctor Tian Yang ran into the prime minister before he screamed. As soon as he came in, he said: "The Qin people attacked my city gate with artillery. Please ask the temple master in the palace of King Yun to dig the soil to block it."

"No." Tian Jian shouted "No." Before the ministers' eyes, he shouted "No". He was actually extremely panicked, but in front of the ministers, he must maintain the majesty of the king, so he had a stern face and suppressed his trembling body and struggled. However, at this time, another cannon sound came from outside the city, and he could no longer sit still. He collapsed weakly on the ground on one side of his body.

"Long live! Long live! Long live Qin!" The sound of cannons sounded, and the Qin soldiers who knew that they also had witchcraft in their friendship shouted together. The shouts spread throughout Linzi like a tsunami. The common people in the city ran around in panic, and some Qi soldiers on the top of the city abandoned their soldiers and wanted to escape.

"Long live! Long live! Long live the Qin Dynasty! Long live! Long live! Long live! Long live the Qin Dynasty..." The troops attacked the enemy, followed by the enemy's plan. The Qin army's attack on the military broke out this time achieved an incalculable effect. Mou Zhong, who was standing on the city wall, couldn't help but tremble when he heard this cry, but reason told him that he must find a way to suppress the momentum of the Qin people, otherwise the Qi State would be destroyed.

‘Boom, boom…’ The cannons aimed at Shenmen under the city began to fire volleys, and the gate that was first tested after several rounds suddenly exploded. Seeing this, Mou Zong shook his whole body and shouted: “The cannon is fake! The cannon is fake! The artillery of the Qin people is fake!”

"Scream! Scream!" Mou Zhong, who was excited, pointed at the Qi soldiers on the city and ordered: "Scream! It's a little faster! The Qin people's artillery is fake!!"

The sound of cannons was roaring, and the distance of 600 meters was still too far for twice the charge. Only a few shells hit the city gate. The initial velocity of the stone bombs fired by Jing Bird was difficult to exceed 80 meters per second. Even if the cannon was reduced, the initial velocity of the cannon was more than 200 meters per second. As long as the shell hit the city gate, the city gate would be a hole. The suspension gate behind the city gate was shocked and cracks appeared at the same time.

Although Tian Yang ordered people to block the doorway, the doorway was full of carriages discarded by doctors, and the bricks and rammed earth could not be transported out at all. Sima of Shenmen could only order people to drag the carriages with broken axles out of the city doorway first, and then transport bricks and stones into the doorway. This is also the reason why the Qin army chose Shenmen. If the Qi people wanted to block Shenmen, they would have to clean the carriages first, and they would have to block them. After they had finished cleaning, the hanging door had already been broken by their own side.

"Shoot—, shoot—" The cannon exploded, and the cast iron fragments swept across the board, and the gunners around were either killed or injured. Recently, a worker was cut off half of his head by fragments, and blood and brain matter were mixed all over the floor, making people dare not look at it. The other artillery workers were worried, and no one knew whether the next one was himself. Zhong Dan could not care about so many. If the cannon could not open the Shenmen, the Ji army without siege equipment could only wait for Wang Jian's army, and it would be too late at that time.

‘Boom--!’ Under Zhong Gan’s strict order, the artillery continued to roar, and a shell hit the main gate of Shenmen. The city gate was broken, and the hanging gate behind it was also hit, and the buzzing sound echoed in the city gateway.

Wu Ji and Ye Shun stood forty steps behind the cannon, which was a safe distance. When the cannon exploded, the two of them couldn't help but look at each other. They were both smart people. Some of the previous explosions were operational errors, but more of the reasons were caused by the cannon itself.

Wu Ji had seen the Chu army gunners use artillery, but he had never seen a blow-off. But even though he knew, things could only be hidden in his heart. Ye Shun was a great craftsman in Shaofu. Although he was not familiar with artillery, the fire-off-official bombardment had exploded one after another. With the intuition of the craftsman, he had roughly guessed the problem of these cannons. If not, how could the Jing people hand over the important weapons of this country to the Qin Dynasty?

At this moment, the two of them looked at each other, and both sides saw the worry in each other's hearts, especially Ye Tun. The more the artillery exploded, the fewer and fewer, and the king would definitely have to cast the Shaofu. Ye Tun carefully checked the barrel of each cannon. It was definitely not cast, and casting could not be so smooth and dense. Casing would inevitably create some breathable pores on the surface of the bronze ware;

At the same time, it is impossible to cast so round. The model of casting is made of clay. The mud mold is unevenly dry and uneven on the surface. This concave and convex will be transmitted to the surface of the object when casting, so it must be polished after casting. The Baidi craftsmen brought to Xianyang by Lord Bai Di cannot solve this problem. Ye Tun has seen their skills, and they are also clay mold casting.

It is a problem to not cast the original appearance, and it is probably not cast the original size. These cannons weigh 6,000 Qinjin, and the nine tripods cast by the Zhou people before were less than 3,000 Qinjin. This is not the twelve twelve gold men in front of Zhangtai Palace, weighing thousands of stones. The gold men are just like a cannon, and the bells pay attention to the tone.

The same is true for artillery. The most important thing about artillery is to be strong and durable. If you want to cast a copper bell that is more than one meter long, with a round cavity inside and weighing 6,000 Qinjin, Ye Shun believed that Shaofu did not have this skill.

His judgment was basically accurate. In fact, in the 16th century 1,800 years later, that is, before the 16th century of the Western calendar, the Ming army rarely had artillery of more than one thousand kilograms (600 kilograms), most of which were less than five hundred kilograms [Note 18]. It was not until the Red Barbarian cannons were introduced that under the guidance of missionaries, the Red Barbarian cannon weighing two or three thousand kilograms were cast.

If the Ming army said that the artillery was over a thousand pounds and the Ming army did not need it, or, as Qi Jiguang said, "There were old generals who used the stools, weighed more than a thousand pounds, and they could not move their length... After one shot, if they dared to put medicine in, they would have to rise up again, and they would not lift it up even if they had to lift it." Or, if (large Folang machine) "If you use it in a boat, you may lose one inch of the mouth when you cast it, your identity would be reduced." It is because the cannon is too heavy and too powerful, so you don't use it, that's wrong.

In the early Ming Dynasty, there were all artillery and iron, but Qi Jiguang asked the large Folang machine to "not restrict the mother's gun, but not the copper and iron, and the son's gun must be made of mature iron." Bi Maokang also emphasized in "Military Arts Pictures" that artillery "must be trained to be made of very skillful iron", so that the heavy artillery in the late Ming Dynasty, such as Ye Gong cannons, Weiyuan cannons, destroying cannons, and even light cannons such as Thunder cannons, and mines and even cannons were all forged from mature iron.
