If it is appropriate, Mozi is extremely pleased.

Shi has not systematically learned the art of defending the city, unlike the bird slippery It took more than ten years to obtain the true biography of Mozi.

But just based on some things he heard on weekdays, he can summarize the essence of many city defense techniques, which is what Mozi appreciates the most.

In Shi's view, in his words, Mozi attaches great importance to data, to the point that he hates to write clear and detailed data in every detail.

The reason why he asked Mozi about his task was because in the Mo family's city defense technique, they also cared about the construction of reference objects.

At regular intervals outside the city, a special reference object was built to calculate the number of enemy troops, the distance they camped, the number of miles apart, and so on.

In the absence of a reference, the eye deceives the observer, resulting in a huge error.

In the case of a reference, it is the mathematics that has not been easy to observe these distances, not the eyes, so it is more accurate.

Outside the city that looks like a plain, in fact, the ink artist still leaves a lot of references within the range of his eyes to calculate the distance.

For example, there happened to be a boulder a hundred paces away from the south gate, which was transported by the Ink Artist with levers and rolling logs, in order to accurately determine the distance of the enemy army.

For example, the height of the temple is determined, and the distance from the masonry camp is also determined, and the distance can be determined by calculating the shadow and then judging the distance according to the rest of the references.

These detailed figures are an important part of the Mo family's defense of the city, and they are also the key to whether they can succeed in one hit in the future.

Relying on the soldiers and low-level nobles in the city, they made a posture of counterattacking out of the city, and used the short-term chaos of the Chu people and the reference left on the ground to judge the distance between the various feudal armies of the Chu people, the time of support, the speed of mobilization, etc., so as to formulate a more perfect plan.

And computing is what Shifu is good at.

This kind of calculation is also the essence of Mozi's understanding but not oral transmission, and being able to think of this problem for the first time shows that he has enough talent to comprehend the art of defending the city.

Manpower is exhausted, and he hasn't learned much about defending the city in recent years, but he has proven that he can learn it.

This is very important in Mozi's view, he has always paid attention to the talent of his disciples, and once wanted to learn archery, literature, sword, and city defense disciples, Mozi observed and told this disciple very bluntly, you are not a national scholar, don't think about learning so much, you can't learn.

Mo Ziyin said with a smile: "Since you know the essence of it, it is most appropriate for you to do it." ”

"You also said that the Chu people have many feudal monarchs, and the nobles cannot fit in with each other, and they have their own ideas. Although the king of Chu came in person, he could not prohibit the order, and the cooperation between the nobles, feudal monarchs, and county dukes could not be tacitly understood, and only the three armies could be used in a dignified and upright formation. ”

"He also said that on the customs of the Six Kingdoms, the Fu Qi formation is heavy but not strong, the Qin array is scattered and fights by itself, the Chu array is not long in order, the Yan array is guarded but not left, and the Sanjin array is ruled without use."

"The Chu army seems to be in formation, but in fact, it is precisely because they can't fight without being organized that they have to be organized. Even if it is rectified, it is still not long, and it can be seen that it is difficult to coordinate between the soldiers of Fengjun County, which we can use. ”

Shi agreed, the Mojia family has a complete set of observation tools, there are a lot of handicraftsmen in the house, each handicraft industry has its own measuring tools, Mozi uses them, plus in Pei County to prepare for the construction of water conservancy and other things, these tools are also complete.

Although it is simple, the effect of careful calculation is definitely several times stronger than no calculation.

Shi Dao: "The disciple thinks that this matter can be done well. Calculation, nothing more than relying on rules, moments, rulers, ink lines, sun shadows, triangles, oblique rods, etc., the disciple happens to be good at. ”

"It's just that I think that the disciple is the leader, but he may not be able to fight with the army, and I am unwilling."

Mozi said with a smile: "I said a long time ago that if you want to do things well in the world, you must make the best use of them. A blind man, do you have to ask him to look out for the enemy? Can't you just let him listen to the enemy digging holes? ”

"Your swordsmanship is too poor, and there are many other things, I would rather let the swordsman guard you than spend any more time learning swords."

Speaking of which, he had already made the same joke for the second time: "Besides, if you harm the world, there are thirteen swords to restrain you." If you have the swordsmanship of Gongzaiye, and there will be guards in the future, these thirteen swords will not help you. ”

Shi Haha laughed a few times, and said in his heart, Mr. forgot to make such a joke before? Or is that really what you think?

Mozi only said casually, avoided this matter, and said: "If that thing is done in the future, your calculation will be no less than going into battle to kill the enemy in person." Therefore, do not slack off, and be sure to do a good job. Whoever you need, come to me. This is the first priority. ”

"You don't have to worry about the rest. You also go to prepare the tools you need. ”

Seeing this, he didn't say much, and took the order to retreat.

…………

A few days later, in the Chu military camp, the night was the most relaxing time.

Tonight the moon is short, and it is almost impossible for the army to launch a night attack at this time, which requires a very high level of organization to complete.

In the event of a night attack, the army will only stand still and cannot panic, so as not to become more chaotic.

After dark, except for the sound of bonfires, loud noises were forbidden in the camp so as not to disturb the army.

This needs to be strictly ordered, so there are endless things like a group of people sitting and beheading.

Those who were propagandized by the Moshi a few days ago have already been arranged to the rear, and once some words spread in the barracks, there will be endless troubles.

In the military tent of the king of Chu, Xiong Dang, the king of Chu, was discussing with a series of important ministers about cutting wheat in the next few days.

If you want to cut the wheat, you must have enough manpower, and you must finish the harvest before the rain continues, because the wheat is easy to germinate and fall easily.

Zhao Zhiai said: "Your Majesty, in the past, there was food, and most of the autumn days had little rain. The method of the ink man to stay in the wheat is between Meng Zhongxia and there may be a lot of rain. It has to be collected. ”

The king of Chu said yes and said, "The widow also has this intention. Now that you collect more, you can transport less from Chudi. The people also need to eat along the way to transport grain, and it takes three less to transport one load. It would be best if wheat could be cut outside Shangqiu City for military rations. ”

At this time, the weights and measures were chaotic, and among the various strange weights and measures, the state of Chu used Dan as the unit of measurement of Yulu. The bell used by the Qi country, the basin used by the Wei country, and the stone used by the Sanjin Dynasty were different.

The Chu people often fought for hegemony, so they were very experienced in such things as long-distance grain transportation, and the King of Chu was also very sober in his heart because of the consumption along the way.

This time against Song, he could only win but not lose.

Not only the status and prestige of the king of Chu himself, but also that only when Shangqiu surrendered could he use the power of the Song people to help the north fight for hegemony.

However, in the face of the Mo who defended the city, the king of Chu had concerns, and from the high tower, the city was in good order, and he was not panicked at all, and it seemed that he could go out of the city at any time to launch a counterattack.

Once the troops are divided to collect wheat and transport grain, I am afraid that the Mo people will take the opportunity to sneak attack, and if the troops are insufficient, I am afraid that they will be broken by the Song people and their morale will be low.

Xiong Dang paced for a long time, and said slowly: "In my opinion, we still have to attack the city, so that the city is tired, thinking that we may attack the city at any time, so that we can concentrate our troops to cut wheat." ”

This kind of siege is meaningless, just to consume the strength of the city, it is natural to use those lowly soldiers.

The real warriors are not used at this time.

Zhao Zhiai said: "Your Majesty, if this is the case, you might as well use those soldiers who have been bewitched by the ink man in those days. ”

The king of Chu thought about it for a while, and then he understood the cleverness.

If these soldiers go back, I'm afraid they will still remember the indiscriminate words that the ink man said, and it is best to die here.

The second is to get rid of these people by the hand of the ink man, so that the rest of the Chu people can see that the ink man does not not kill, but on the contrary, he does not blink an eye when he kills people.

After a little deliberation, we decided which engineering method to choose.

Methods such as attacking the city with ants, filling in the trenches, storming the ladders, and ramming the city gate with a car are impossible to work if they only rely on those apprentices, and they are blatant, and once they cannot be attacked, it is easy to cause instability in the morale of the army.

In this way, the only options left are digging holes in the ground and shooting sheep.

Although the ink man is good at guarding, the king of Chu thinks that the Chu army has been making a posture of besieging but not attacking these days, and there may be slackness in the city.

Besides, even if you can't break it, it's nothing. The method of sheep mounds cannot break the city at most, but it can still cause deterrence in the city.

Even if the excavation of the cave fails, the dead will not die in plain sight, and it will not cause the soldiers to be frightened when they see it.

In the final analysis, the king of Chu is still extremely afraid of the Mo man's city defense technique, and he is afraid that once the all-out siege of the city cannot be broken, the Mo man will take advantage of the situation to defend and counterattack, and let the Chu army fail.

King Chu said: "Although it is not full strength, it also makes Shangqiu City panic, and he does not dare to fight easily, and he will harass us to cut wheat." After repeated times, the city was tired, and even if it knew that we were just pretending, it was too late. ”

The nobles in the tent did not object to this opinion, anyway, they did not need to use their own private soldiers, nor did they need to use their own elites, and this kind of thing should be left to those apprentices who listened to the bewitchment of the ink man.

If the soldiers don't do it, they can be killed according to the law, and the rest of the soldiers in the camp will not be dissatisfied.

Each nobleman has his own elite power, and these elite forces are the foundation of their survival, because the apprentice can be recruited as long as he has a fief.

And if you rely on apprentices to fight, I'm afraid there will be no need to fight this battle, in the eyes of the Chu people, the chariot aristocracy is the foundation of the decisive victory.

…………

Soon, the part of the Chen people who the Chu army heard the Moshi preaching that day was gathered, one part was close to the city wall, digging the earth mountain and piling up sheep mounds, and the other part was preparing to dig tunnels.

These two need to be done together.

The soil goat mounds need to dig the soil, and the tunnels also need to be dug up, and if you want to dig the secrets, the soil dug out of the tunnels must be found to make the city unvisible.

In the past, it was common to build a wall under false decoration, so that the soil from the excavation tunnel could be pretended to be hidden in the wall.

If you build a sheep mound, you can directly pile up the soil in the tunnel on top of the sheep mound, so that it is not easy to observe the situation in the city.
