Chapter 182 Infinite Changes and New Strategies ([-])
The Chen people who were ordered to dig tunnels and build Yangmen did not know the real intentions of the king of Chu and the nobles. In their view, this was just a normal way of attack.

It is impossible to build the Yangmen directly under the city, so we can only choose to start outside the range of the feather arrows on the city, and pile up little by little, constantly taking advantage of the condescending advantage and relying on archers to suppress the city head, and gradually approach.

This is the most stupid way in the eyes of the Mohists, but the so-called big tricks do not work, if the accumulation is successful, it will put a huge pressure on the city wall.

Digging tunnels is also a common method used by the siege side, and it is also an extremely useful method.

Instead of digging tunnels directly into the city, they dug the rammed earth wall foundation close to the city wall to collapse the city wall.

If this method is combined with gunpowder, it is almost an unsolvable siege method for the city walls of this era.

However, not to mention gunpowder, the people of Chu didn't even have all the iron tools, and many disciples still used the most stupid way to dig.

Fortunately, there are many craftsmen on the side of the Chu people, either in copper mines or in other mines, such things as digging holes can still be done.

Most of the Chen people who were excavated were people who had heard the propaganda of the Mohists. There had been strict orders before that the words of the Mohist were all nonsense, and it was forbidden to spread them in the barracks.

There were people watching from behind, and these people were worried that someone would inform them, so they didn't say a word, but kept digging according to the command, trying to get closer to the city wall.

…………

In the city, a blind man was crouching at the mouth of a well, listening to a pottery urn covered with cowhide. His ears suddenly moved, he held his breath, and his heart was pounding.

He is blind and was originally unknown in Shangqiu City.

But Mo Zhe recruited those with keen hearing this time, not only could he eat wheat cakes every day, but if he could find out the movement of the enemy, he could also get a bounty.

If the princes and nobles said it, the blind man would naturally not believe it. Many nobles would make such a joke just for a laugh.

But if it was what the Mohist said, the blind man would believe it without even thinking about it, and he was convinced that his hearing was excellent, and he might be able to get those bounties if he was not sure.

The blind man has never touched real gold, nor does he know its weight, but he has heard of its value.

The gold is not from the Mohist, but the Mohist is used as a guarantee, and Song Gong will always give it in the future. At least the blind man believes in the Mohist.

The blind man felt that his wealth was right in front of him, so he listened very carefully.

The subtle sound propagated through the land, amplified at the mouth of the well, and then amplified in the pottery urn, vibrating on the cowhide above, like a huge stethoscope, and these blind men with keen ears can clearly distinguish the direction.

The blind man coughed lightly, and an ink master came over immediately, holding a square ruler in his hand, determined the position on the azimuth plate set up next to him, spread a piece of grass, and waited quietly for the blind man's guidance.

The perennial dark life has allowed the blind man to develop the ability to listen to sounds and distinguish his position. Not only can he hear the sound, but he can also distinguish the direction through the sound.

It wasn't the first time that the ink man next to him followed these blind men to listen to the movement, but it was the first time he followed the instructions of the secretary to determine the direction with a square ruler, and then drew the direction on the grass.

In the past, after hearing the movement, the blind man used different wellheads to judge which well was the closest, so as to determine the location of the enemy's digging hole.

But this time, Shi said that he could not only judge the location and direction, but also roughly judge where the enemy's tunnel was dug.

Most Mohists believe this statement, they have long been too lazy to be shocked, but they don't know what to do.

Since the giant also believed it, they had no choice but to follow suit.

Tens of steps away, more than a hundred steps away, those blind men with sharp ears heard different movements, and the following inkmen also drew these movements on the grass one by one, marking the location.

In a large room, some people from Shizheng and the secretary, and a few carpenters were busy making some measuring tools.

On the large piece of paper behind him was a simple map of Shangqiu with various signs outside the city.

Enemy watchtowers, boulders left by the Mohist to measure distances, some rivers, marked fields, small hills that cannot be moved, and so on.

On this map, some strange small squares are marked to measure distance, and some thin lines are drawn on it.

Shizheng and some carpenters tried to get a small level and a semi-circular scale plate to calculate angles so as to calculate distances.

These tools have never appeared before, but they are all extremely simple. The only thing missing is a table of trigonometric functions. Unfortunately, it takes a lot of manpower and a lot of time to get this thing out.

It's also fortunate that the Mohists need to use it for defending the city, otherwise the cannon will not come out, and the development of trigonometric functions will not be so fast. Sometimes war is really one of the driving forces of mathematics.

What can be done now is to use a ruler to calculate roughly, to calculate some sines and cosines with large errors, etc.

When Shi was busy, a Mohist walked in with the giant's warrant, whispered a few words in Shi's ear, and Shi followed him out to Mozi's military tent.

Inside, the Mohists gathered together, and Shi guessed that something might have happened.

After the unrelated people left, Mozi smiled and pointed to the outside of the city and said, "The people of Chu are actually digging tunnels to attack the city by building sheep as a cover. Shi said before that the people of Chu might pretend to attack the city to cover up the siege." Mai, it seems to be right."

Speaking of this, Mozi was a little dissatisfied, and he clicked his tongue and said: "More than [-] years ago, I fought against Gongshu Ban in Chudi. I have already mentioned the method of digging tunnels to attack the city."

"Ordinarily, those people I heard about back then still have people who have never passed away. How dare they attack the city like this? This makes me dissatisfied."

Everyone laughed, and they could probably understand why Mozi was dissatisfied: I have warned you that it is useless to do so, and you still do it, which clearly shows that you don't take my words seriously.

This kind of extremely proud dissatisfaction.

Mozi shook a few pieces of paper in his hand, and said, "Shi, come here now. This is according to what you said. Draw the direction that the Chu people heard when digging the tunnel. You must find out the location as soon as possible."

After picking up those few sheets of paper, there are enough samples, and the intersection point can be found in the way of connecting lines, which can be roughly judged in advance.

Gong Zaoye said with a smile, "Mr. once said, to respond to bandits, rush to the acupoint. If you haven't found the acupoint, be careful not to pursue it."

"Before the direction of the enemy's tunnel is determined, the defenders must not dig in advance. First, it is easy to hear clearly, and second, it is easy to dig in the wrong direction."

"I used to defend the city with my husband. When the enemy just dug, it was difficult to be sure. If you can, you will make another contribution."

Gongzaoye is not a compliment, if you haven't found a cave, don't pursue it carefully. If these six words are not done well, it is likely that the enemy's caves have been dug, and there is not enough preparation here.

If you don't prepare a little in advance, you can take advantage of it.

Hearing Gong Zaoye's words, Mozi smiled and said, "Shi's contribution has already been made, how can it be now? It's just that his contribution is mostly hidden, but I, a giant, can see it."

"Now we have iron tools such as shovels, iron chisels, and shovels, which are very convenient for digging soil. Presumably, Chu people may not all use copper tools, and the speed of digging is very different."

"It's just how can ordinary people notice such credit?"

Gong Zaoye said: "The disciples understand what the master said. That's exactly how it is."

After being modest, he said, "Sir, since we can prepare in advance, how are you going to deal with the enemy and dig tunnels?"

Mozi has no pressure to defend Shangqiu, so it is best to take advantage of this opportunity to pass on many of his techniques of defending the city.

Shi and others have only roughly heard of it, but after all, they are not as good as Qin Huali who stayed in Pei County for some details.

It turns out that Mozi has many methods to deal with the tunnel siege.

In general, there are four types.

A small group of elites raided in the tunnel; fumigated with poison; irrigated with water; shot with short crossbows.

The short crossbow is made by the ingenious craftsmen of the Mohist school. It is most suitable for use in such a small place inside the tunnel. It has an extremely fast firing rate, but it is not very powerful, and most of the tunnels will not wear armor.

Shi listened for a while, and then said: "Sir, if the people of Chu use tunnels to dig, and if you are confident in getting rid of this method, you might as well use other methods."

"If it's inside the tunnel, the people from the Xuanyi Department will also follow and use smoke to make the enemy escape, but before fleeing, they have to say a little more reason."

Someone questioned: "Shi, your reasoning is for those peasants, businessmen, and businessmen, but not for scholars and nobles. If the tunnel is dug, the first batch of attacks may be scholars and nobles."

Shi Que laughed and said, "But now we have iron tools and nine-number geometry that can predict the direction of the enemy's digging in advance, so as to seize the opportunity."

"Before the tunnel was dug, how could the scholars and nobles dig it themselves? The people who dug it were either child slaves from the mine or recruited farmers. These people are the place where the Propaganda Department can reason."

"so……"

He glanced at Mozi and said with a smile: "Sir, if we can scare them away and smoke them away without killing them, firstly, we can make these people talk more about the righteousness of Mozi after they go back, and secondly, we can make them go back to Mozi." Chu people no longer dare to use the method of digging tunnels."

"They may not be afraid of death, but they must be afraid of the living who speak words like land, silverfish, noble and humble."

Mozi laughed and said, "Okay! Let's smoke it then."

He called out the name of a Mohist craftsman, and said: "Let the pottery be the moonlight, two feet five inches long and six circumferences. He will be judged, and he will put it in the cave. He will cover it. Paint, do not burn the pillars. Do not burn the pillars. The pillars are good at painting the borders of the sinus, and do not let it leak. This is the case on both sides, and the acupoints are in front. Press the ground, put the health in it, do not fill it. Gray Kang grows The five sinuses, both left and right, are similar. The mouth of the acupoint is a stove, which is like a kiln, and it can accommodate seven or eight people. The left and right sinuses are like this, and the stove is four. Therefore, it is necessary to order those who learn to do things in the Ming Dynasty not to leave the mouth of the stove. To connect the plates, the points are high and low, and Guangshan is the degree. Let the sinuses be rescued. The acupoints are met, use the plate as it, save the sinus with a spear, do not let the sinus be blocked; the sinus will be blocked, draw the plate and close it, pass through a sinus and block it, chisel the sinus, pass the smoke, and the smoke will pass , Drum it up quickly to fumigate it. Listen to the left and right sides of the acupoints from the inside of the acupoint, and rush to the front, so as not to allow it to go. If you collect guest acupoints, plug them with firewood and paint them, so that there is nothing to burn!"

The Mohist took the order, and I understood it: in short, it is to make ventilation pottery pipes, just like gas pipes, and use a blower to blow air here, and pour a lot of smoke from these pottery pipes into the tunnel. Inside.

Then use wooden boards and the like to block the thick smoke on your own side, and rely on the sealing of the pottery pipe to continuously blow the thick smoke into the opponent's tunnel, forcing the opponent to escape.

Since the size is clearly stated, it is not the first time how to make it. These seemingly important issues are not important to the Mohists.

The only thing that needs to be paid attention to is whether the appropriate geometric intersection method can accurately judge the direction in which the Chu people dug the tunnel.

　The pottery pipe ventilation technology is very well mastered by the Mohists, which is why things like iron smelting ventilation can be carried out so easily in Pei County... The Mohists have sufficient technical reserves.The 80-[-]-meter ventilation pipe can be sealed, which is convincing.
