"Why is this?" Zhao Zihao looked at Jiang Cheng with a puzzled look on his face.

"If the enemy will come to attack the city again tomorrow and see that there are puppets on the city, we will definitely think of this. We must use the city as much as possible to eliminate the enemy's vitality. If we use puppets again, the enemy will not attack again." Jiang Cheng shook his head. He was not a fool, and he knew that the attack was ineffective.

"What should I do? If I only guard the city with the soldiers, it would be difficult to support it." Zhao Zihao frowned.

"The puppet is too eye-catching. Today I am thinking, why not take its appearance and use a wooden frame as a pillar and a mechanism!" Jiang Cheng spread the sketch he had already drawn and smiled: "Look, behind this city wall, two brackets are placed horizontally, with long spears tied up, and gears are used as hub..."

"Brother Jiang, just say the effect. I don't understand what you said." Zhao Zihao said with a wry smile.

"Is it effective? Originally, the puppets could only stab the front. In fact, after removing the puppet shell, it was similar to this one. They only had a personal outline, but without this outline, they could have two more arms in the middle, but not stabs, but chops. Moreover, this mechanical hub is at the bottom. As long as the hub is not broken, even if one or two limbs are broken, it can still kill the enemy normally. In this way, even if the enemy is usually holding a blunt weapon in hand today, it will be difficult to break it."

Although the puppet can move freely, it also limits the agility of its hub. The core hub of the puppet can only be in the abdominal cavity with a large space and cannot be placed at the bottom. This is also the reason why so many of them were destroyed at once today.

"And this approach is easier and not as eye-catching as a puppet. It can attract the enemy to attack again." Jiang Cheng said with a smile.

"Wonderful!" Zhao Zihao said happily when he heard this. As for the fact that it must be fixed in advance, this is not a big deal in his opinion. Anyway, these things are made for use in defending the city. What should we do when walking freely? Are these simple mechanisms and puppets patrolling the city?

"In this way, the enemy will not easily attack the city, and the soldiers of Wurui Camp also have a chance to breathe." Jiang Cheng smiled and said, "Maybe you can concentrate your extra troops and take advantage of the enemy's retreat to rush to kill!"

After all, this mission will help defeat the enemy, not defend the city. If there is a chance, Jiang Cheng naturally wants to take the opportunity to defeat the enemy. However, the number of enemy troops is still large now, and he may lose the decisive battle, but he will only pursue it once, and it should be enough to defeat the enemy's aura.

"This..." Zhao Zihao was a little hesitant when he heard this. If it were before, he would have refused without hesitation. But now, the mechanisms created by Jiang Cheng have relieved the pressure of defending the city and can also produce many soldiers. If the enemy retreats and takes the opportunity to fight, he is 70% sure that he can succeed. As long as he is not greedy for merit and advance, he can win a small battle and encourage morale.

"If we pursue, according to Brother Jiang's opinion, how should we pursue it?" Zhao Zihao suddenly looked at Jiang Cheng. He wanted to see if the young man's mathematical skills coincided with his own military strategy: "Or attack those main Warring States countries?"

"No!" Jiang Cheng shook his head and said, "If we defend the city, our army will naturally have to pick up these elites to fight with the help of the city wall and the mechanism. But if we pursue it, I think it's better to fight with the weak. In the past two days, I have found some interesting things."

"Oh?" Zhao Zihao looked at Jiang Cheng curiously when he heard this.

"Those soldiers of the Warring States Period will be in order and keep a high degree of vigilance even if they retreat. On the contrary, the soldiers of these countries who do not contribute much are extremely casual and even have no rules to find. We will take them to take action, and it will be easier to succeed. Secondly, if we are not good at military tactics, I don't know if we can drive these people to attack the military formations of the war factions. In this way, it will not only have greater lethality, but may provoke conflicts with the other party."

"Miscellaneous!" Zhao Zihao looked at Jiang Cheng in surprise: "This is also a mathematical technique?"

"Some are, some are not. People's psychology can be counted by mathematical techniques as a whole, but people are individuals after all. Such inaction will disrupt the brave and diligent people's team. Even if the general takes into account the overall situation and does not care about it, they will definitely feel resentful in private. These are not something that mathematical techniques can be calculated, and can be called mental techniques." Jiang Cheng shook his head.

People’s minds are the most complex. Data plays a big role in this. One thousand people have a thousand ideas, and any detail may change. It is difficult to calculate through mathematical techniques. What he can do is to determine the probability from the overall situation. As for personal thoughts, there is actually no need to pay attention to it. It is difficult for personal will to resist public intentions.

"If Brother Jiang joins the army, he may be able to become the chief general in less than ten years." Zhao Zihao shook his head and smiled.

Jiang Cheng refused to comment. His main focus is on studying now, but the war has also made him quite interested in war.

The eight-gate golden lock formations he had comprehended were also battle formations. If he really joined the army, he would definitely shine. Unfortunately, the time is too short now. Even if these soldiers set up the eight-gate golden lock formations, it would be difficult to exert its power. It would be a pity that they could not try it out.

"Then I'll gather people now."

At that moment, Zhao Zihao gathered the group of craftsmen and started construction on the city wall overnight according to Jiang Cheng's instructions. He must complete the arrangement of the mechanism that Jiang Cheng had imagined before tomorrow. In order to avoid mistakes, Jiang Cheng did not rest and followed a group of craftsmen to work overnight.

Zhao Zihao personally selected a group of elite soldiers, fed and drank, and rested in the city to deal with tomorrow's battle.

In the early morning, Bai Zhirou and others who had been resting for two days appeared one after another. Two days also made them feel relieved. Although they were still uncomfortable, they could not help feeling a little guilty when they saw Jiang Cheng constantly calculating and designing for the task.

"My junior brother, what do you need help?" Huo Wei found Jiang Cheng and said with a wry smile.

This was originally what they involved Jiang Cheng, but in the end, Jiang Cheng made the most efforts, which made them very ashamed.

"Standing on the city wall today, persevering until the battle ended." Jiang Cheng turned his head and looked at everyone: "We are now hiding in the sect, but in the future, this kind of thing will inevitably happen again and cannot escape."

These people are good helpers, each of them is quite talented in mathematics. Jiang Cheng is proficient in mathematics and naturally understands the value of a mathematics master. Although he has not yet figured out what to do in the future, he wants to gather these people around him.

"Okay, don't worry, junior brother." Everyone felt a little ashamed when they thought of their unbearable performance before.

"There are not many defenders in the city today. If there is any mistake, you will need to make up for it!" Jiang Cheng looked at everyone and said, "Putting out the armor, a disciple of the Tianyuan Sect, it is not a glorious thing to die at the hands of the soldiers."

“Woooooo~”
