The methods of siege listed in "Mozi Preparing the City Gate" are only twelve types of sieve, hook, rush, ladder, ***, rush, hollow, ants, twelve. Among them, Lin, as early as the Emperor of the Book of Songs, there was a sentence of "using your hook to support, fighting with you to attack Chongyong". When you approach the car, you can come to the city and then you can come to the defenders, so it is called Lin. In other words, this is similar to the medieval siege tower, which is about ten meters high, with wheels underneath, and soldiers are hidden above. When siege the city, they can be pushed to the city, and the upper level soldiers can come to the top of the city.

The reason why Lin was listed as the first of the twelve methods of siege by Mozi is actually the most effective, fastest and least loss in the siege battle, and it is also the most troublesome way for the defenders to attack. This is equivalent to the reversal of the local advantages of the attack and defense. The attacking side located in the car is at a high point, and the defenders on the city will fight back and lose all the local advantages.

Facing the attacking side's approach, the Mohist countermeasure was a crossbow chariot. Its arrow was ten feet long, and it was shot with a rope mouth and arrow, and it was rolled up with a grinding mouth. This was to use a crossbow to shoot the arrow into the attacking side's approach chariot, and then rolled up the rope at the end of the arrow, and pulled down the car. In addition to the crossbow, there was also Taicheng or Xingcheng (movable), that is, to build a high platform on the city wall that could extend out of the female wall, so that it was higher than the attacking side's approach or Tushan (Yangqian), and then shoot it with a crossbow.

Taicheng and the city of travel are all made of wood, and it is difficult to build. Although this city can be extended beyond the female wall, if it is far away, it may not be able to fight against the attacking side. It can only be shot with an arrow crossbow and use a crossbow to pull the attacking side backward. This is the fundamental solution. Based on this important consideration, Naojing will risk being captured by the Qin people and rushed to Chengyang to send Jing Bird to Chengyang.

The range of Jing crossbow is more than that of the continuous crossbow. In addition to being able to shoot the car at a longer distance, there is another benefit that it is convenient to pull the car downwards - the car attacks. If it is shot from the front, the rope at the end of the arrow can only be pulled closer and closer. It reflects on the pain of the siege's pushing the car forward. Only by shooting the car on the side of the car and retracting the rope at the end of the arrow can pull the car down.

In the pre-Qin period, horse faces (that is, rectangular circular square tables protruding outside the city wall every other section) were not standard construction for the city. Only a few cities had one or two horse faces in a few locations, rather than later, like the city wall, building a horse face for seventy or eighty meters was customized. The city that Mozi said was not a horse face. Traveling to the city means that this was a feasible (mobile) city, while Taicheng was an infeasible city.

The horse face is more than ten meters outside the city, forming a "典" shape with the main wall, so that the defenders can attack the enemy from three sides, and can shoot arrows on both sides, pulling down the cart. Chengyang City is eight or nine hundred meters long and wide, and the main wall is straight, without a horse face, only the city. The crossbow cart is set up in the city city, which can pull down the cart within a hundred steps on both sides of the city city, and can only shoot arrows at the oblique angle on the city wall outside a hundred steps.

The Jing crossbow is different. The Jing crossbow has a long range. It can sweep all the cars within 400 meters on the wall. If the arrow is fired at an oblique angle, it can pull it down before the enemy's car passes through the moat. In addition, the Jing crossbow is powerful and the arrow is shot very deep. Even if the enemy on the car wants to remove the broken arrow, it will take longer, and the cars have already been pulled down by then.

As the city guard, Chen Gai fully understood the significance of Jingnu to defending the city. He believed that Jingnu was important. But unexpectedly, the officers of Jingnu Camp did not allow him to visit Jingnu, which made people feel unhappy.

"It's outrageous!" Before Chen Gai got angry, Sima Chen Qin, who had just come up to report, was displeased. "The general is the general of Chengyang, and all the soldiers in the city obeyed his orders. You only have six Jing crossbows. What if you can't prepare the enemy's chariot?"

Chen Chuang's concern is not unreasonable. The crossbow carts are set up in the Wengcheng, with ten on each side and twenty on each door. In addition, there are no less than 120 on the city wall. The Jing crossbow has three on each side and six on each door, and there are only twenty-four in the city. At the same time, the crossbow is a continuous shooting weapon, with at least 60 arrows per arrow, and hundreds of more actual combat, ensuring the hit rate with dense continuous shooting; the Jing crossbow now sees only a hundred arrows, so what should I do if I can't shoot at that time?

"Reported to Sima, Jingnu is the secret of Chu State. If you have not obtained the order of the king, you cannot see the order of the Grand Sima Mansion." The crossbow soldiers came from the king's soldiers and had a ban on them. They were not afraid of Chen Bei, and Chen Wang was not afraid of Chen Bei. "As for preparing the enemy's chariot, this is the position of a villain. If you fail to hit the enemy, it is the crime of a villain. I am willing to be dealt with by the general's military law."

"Just rely on these arrows?" Jing Bird's arrows are also different from those of the continuous crossbow. They are thinner and lighter, with oil marks on them. "This is... this is an iron arrow?!" Chen Gai was shocked! The cast iron is extremely crisp, and the ripe iron is too soft, so the continuous crossbow arrows are all made of copper. How can you use this iron arrow to knock down the enemy's car? Could it be that the people in Yingdu are even greedy for the cost of arrows?

"Please don't touch the huge arrows." The iron arrow that Chen Gai was holding was snatched back by a crossbow soldier, and then carefully placed in the groove of the wooden arrow box. Although the arrow was made of evil gold, the arrow box was made of exquisite, and there was a waterproof wolf leather pad inside.

"Great Arrow?" The two pieces were assembled, nearly two tall, covered with tightly covered by black cloth, and they could not see at all. All they could see were the arrows in the arrow box and the uninstalled crossbow components also covered by black cloth.

"It's the huge arrow." Just like the artillery soldiers in later generations, each crossbow has a long one, six crossbows and one company. Now the one who talks to Chen Gai is the company head Kong of the Jing Crossbow Company. He answered seriously to Chen Gai. "Your Highness once said: Whether it is shot or not is related to the light and heavy arrows and the shape of the arrows, so the light and heavy arrows must be customized. The arrows of the Jing Crossbow are eight feet long and weigh 1,600 grams, and the arrows are the same. If the arrows are made well, they should not be moved to avoid hating their shape. In order to shoot far, the building mansion was also made of huge iron."

Jing crossbows were made by Xiong Jing, and naturally the rules set by Xiong Jing. Borrowing the sniper concept, the severity and center of gravity of the arrow are related to the hit rate, so Jing crossbows are made with great attention. Especially this kind of crossbow that pulls down the enemy's driving, the center of gravity of the arrow after the arrow is tied to the rope, and everything is to increase the hit rate.

Kong said seriously, although Chen Gai didn't understand everything, he didn't understand it. He asked again: "Can you shoot ten shots within a hundred steps?"

"Haha..." Someone laughed, it was a few crossbow soldiers. As the chief, Kong immediately turned around and looked at him, shouting: "Ignorance!"

"What does this mean?" Chen Gai didn't understand again. The crossbow soldiers were common people and he was a nobleman. Of course they were rude to laugh at him, but he didn't understand why these people laughed. Isn't he stupid?

"Please atone for the general, and the villain will punish them heavily." Kong Shen bowed.

"Why do they laugh?" Chen Gai asked, "Is it because I said something wrong."

"General, Jing crossbows are not continuous crossbows, and their accuracy is even greater than continuous crossbows. If the Qin people attacked me by the chariot, the general should know how powerful Jing crossbows are." The range and hit rate of Jing crossbows are all confidential, so I can't tell you. After a while, I sent Chen Gai and others away with courtesy.

"It's so great to be cunning to prevent me." After walking out of the city wall for a while, Chen Weisang said.

"This is a mistake. I heard that my eldest son wanted to set up a military academy and recruit students from the nobles of each county, among which there were..." Artillery soldiers were not something Chen Gai could imagine, so he had to change his words, "There was a good school of shooting. For this matter, my eldest son also argued with Ling Yin about the amount of taxes that Ling Yin's mansion would be earned in the year. I think our army would also have Jing Bizhang in a few years."

Many of the matters discussed in the Yan Dynasty were not secrets. The prince wanted to run a military academy a few months ago, and the nobles in the county welcomed this. Most of the royal families who studied in Lantai were royal families, Cheng, Dou and Yuan families after King Zhao of Chu. These husbands had basically no chance of entering Lantai. Even the most powerful Qu Jingzhao tribes in the court had limited places in Lantai, and only a few children entered Lantai.

By the end of the Warring States Period, the number of officials in counties and towns had already been determined, so they should not be increased rashly, and the power of tyrants was very small. Entering Lantai was the best shortcut for the children of nobles to become officials. I just don’t know when the military academy will be opened and what the rules are there.

Chen Gai hoped that the military academy would be opened soon, and Chen Chuangze said: "There are many noble people in the court, and we are not as powerful as water and fire, but we are not far apart. By the way, Jin Gu threatened his father with revenge, so I don't want him to drink the poisonous wine."

Chen Qin went up to the city to find Chen Gaizheng for Jin Jun. With the unwritten rules of Chu State, the generals must be killed. If Jin Jun fails to die, he will break the rules, so the Grand Sima Nao gave him poisoned wine with Feixun orders. However, Jin Jun refused to drink, and even carried out his father Cai County to threaten him. Cai County was a big county, and based on the interests, Chen Qin would not force Jin Jun to drink poisoned wine.

"He really threatened with his father's revenge?" Chen Gai's eyebrows stood up.

"You dare to ridicule the nobles. If it weren't for the war, you must wait for the good look!" On the wall city, Changkong of the Jing Crossbow Company was scolding the crossbow soldiers who ridiculed Chen Gai. These people were lying on the ground, each of them was beaten ten times, and blood spots on their backs appeared. "Pack up the Jing Crossbow quickly, the Qin people are going to attack the city!"

Large Jing crossbows are too heavy and difficult to transport. Borrowing the concept of mountain cannons from later generations, Xiong Jing not only requires that the crossbows are assembled, but also requires that the heaviest parts must not exceed fifty kilograms. This kind of transportation is convenient, but there is an additional procedure before use: assembly.

"Yi." Fighting is not a serious punishment, you can work after the fight. These crossbow soldiers who went north with blood spots naked and began to assemble Jing crossbows quickly. The assembled Jing crossbows were commissioned by the craftsmen sent by the Zaofu. The debugging was not the two frames, but the simple high and low machines that controlled the launch direction.

But except for these craftsmen who were focused on the matter, the soldiers and soldiers in the city were attracted by the Qin people at this time, and they stared at the west side. There, while the drums were making loud noises, the Qin army was surging like a tide, trying to swallow everything they met. This was not a military parade like the moonlight in Xixian County, but a horizontal array that could not be seen at a glance was advanced to Chengyang City.

Countless Qin army flags fluttered in the sun, and the more eye-catching colorful feather flags were angrily in the dust that stirred up. Under the flags, Qin crossbow soldiers, Qin chariots, and Qin savages were all in the array, but in the array were Qin infantry soldiers wearing brown armor, holding spears and spears and beryllium. They held weapons upright, and their soldiers were like forests, stepping forward with the sound of the sergeant's bracelets and drums, and their momentum was unchanged.

"Beat the drum right now?" Chen Gan, who had never seen the Qin army formation, was so scared that he wanted to beat the drum to prepare for war.

"No need. The troops attack the plan, and the second is to attack the diplomatic plan. The Qin people are like this, just want me to be afraid." The attack on the diplomatic affairs is not what later generations think of destroying diplomacy, but to observe the troops before the war: I let you see the power of our army and ask if you are afraid. At this time, Chen Yingzheng tilted his head and squinted his eyes to resist the murderous aura that the Qin army formation exuded. But no matter what, if he lost this time, all the soldiers and officers were scared.

"Put that..." Chen Gai was speechless, and he blushed and cleared his throat and said, "Tell me the order and order Jing Bi to shoot the formation immediately."
