A few days later, the envoys and official personnel of Wei, Qi, Han and Chu arrived at the front line under the escort of a team of soldiers, and the front line had already begun to be busy.

More than 20,000 second-line soldiers recruited by Pengcheng were digging their chest walls and paving roads. A camp surrounded Dangshan City, which was halfway beyond the range of artillery fire in Dangshan.

The observation team composed of envoys was arranged on a dirt mountain 800 steps away from the moat of Dangshan city, which was also the front-line command post for this battle in Dangshan.

These envoys were sent in semi-force. Of course, they also wanted to see how powerful the combat power of Si Shang was in order to make a judgment and affect whether the lord sent troops.

A deputy envoy of Wei State looked at the two cloth and patent-skin hot air balloons floating in the sky, full of curiosity, and said to a deputy envoy of South Korea beside him: "The method of the Mo family's siege of the city looks completely different from before, but in fact, if you think about it carefully, it's the same."

"In the past, we had to pile up sheep and watchtowers to observe the situation in the city. Now we just use flying balls to replace the watchtowers."

"In the past, people with clear ears and eyes needed to stand on the platform to observe the situation in the city. Now they are just using the Qianli Mile Mile instead of those with clear ears and eyes."

"In the past, we had to rush to siege the city wall, but now we used copper cannons; in the past, we used to siege ladders, but now... we still use ladders, hahahaha."

South Korea's deputy envoy smiled and said, "I just said that I understand the will of heaven and change the world. If I think about it carefully, there will be no change. As you said, there was a lord in the past, and now the merchants from Song Dynasty are also lords. They cannot change the world, but they only change the people who benefit the world, and use their theory of profit and righteousness."

These people spoke freely, and the soldiers who were in charge of the guards next to them were all the internal guards of the Supervision and Inspection Department. They were silent and serious, turning a blind eye to those people's words.

There was a telescope next to these people. Several people picked it up and looked at the second-line soldiers who were busy digging pits and building camps in the distance, and smiled and said, "The Mo family is the most popular attack on the city. The Mo people are also a black man. I think they are like a group of mice, digging pits everywhere."

Although it is a bit ridiculous, this zigzag digging tactic, which looks extremely simple and even a bit vulgar, proved that it is invincible in previous actual combat.

It’s just that the essence has been learned from all countries.

Some things look easy, but the true essence is not that easy to learn.

…………

In the tent of the General Staff in the camp, several officers were drawing more accurate Dangshan city defense maps as observed by hot air balloons.

The remaining people calculate the best drop ratio by the matching of cannons on the front of the city, the angle of the city wall, the width of the city wall, and the angle of the expansion.

A staff member held a protractor and a compass ruler, stared at the map for a while, and said to the person around him: "The left side of this place is a river fork, which is not suitable for excavation."

"If the cave is digging here, the distance is not enough. We must advance to a distance of 200 steps away from the city wall to use the method of attacking the cave."

The young staff expertly drew a circle with compass on the map and dug out the crypt to attack, which is a common method of siege.

It is not the zigzag exterior exposed to the trenches used to gather and approach the city walls, but the method of directly digging tunnels to get closer in the "Preparation Cave".

Authenticity is not something you can dig casually.

Because based on the experience of digging pits, mining experience, and previous experience in defending the city, such crypts close to the city walls can only be dug at most three hundred steps without a ventilating vent.

If there is too much air, the people in front will be suffocated to death and will not be able to fight at all.

As for what kind of terrain can be dug without water seeping, how close it needs to be to dig... This is the rest of the General Staff on Si Shang.

When you dig a hole, you will know that crypts can be fought. The problem is how to dig, how far you dig, where to dig, and how to dig.

The Dangshan City on the drawings in the young staffman's hand is like a hedgehog that explodes with thorns, with a total of sixteen raised corners, that is, sixteen concave surfaces.

The distance between each convex angle is about 200 steps, which is exactly the maximum range of the crossbow and musket. Attacking any concave surface will inevitably face projection strikes on both sides.

Because the total side length of a polygon must be greater than a line segment equal to its longitudinal line, and is about three times that of this line segment, for the siege side, the number of enemies on the front line is actually always a disadvantage.

This is the biggest difference from Sifangcheng before the Gunpowder Age. Although Mozi proposed the idea of ​​walking on the wall and horse face with a crossbow before this, it was not perfect.

Dangshan is not the city wall of the era of rammed earth ladders, but the first regular gunpowder era city defense outside Si Shang. It is also the confidence that the emperor's clan believes can resist Si in the first half of the year, which makes various countries interfere.

A large amount of stone in the Dangshan area is used as the construction of city walls. There is also a thick brick and stone structure slope outside. The outside is surrounded by a moat with a width of about five steps. It is stagnant inside and it is very slump and cannot be solved by cutting off the upstream or diverting the flow.

The methods of siege are ever-changing. Just as the deputy envoy of Wei State, they are actually the past things. Mozi had already summarized the methods of siege before joining the Mo family. The overall strategic thinking has not changed, and all that has changed is the tactical changes of new weapons.

The task of the staff is to formulate various possible attack methods, do the work on the map, calculate the assigned manpower, firepower support, artillery arrangement, etc., and finally the commander decides and chooses the method of siege.

Acupoint attack is just one of the methods, and unlike the previous acupoint attack, today's acupoint attack mainly involves digging holes on the foundation to bury gunpowder, which will be more efficient if it is successful.

However, this is also the cruelest thing for the siege.

As early as when Mozi was defending the city more than 20 years ago, he proposed a more cruel counterattack method against the attack of the crypt.

Including, it is not limited to irrigation, using skin to release smoke, using sulfur to burn to create suffocation, and using poisonous weeds to create various poisoning.

By using changes in the water level of the well and the sound of the pottery jar, you can determine the direction of the attacking party's excavation tunnel and make targeted counterattacks, it will have a great blow to the morale of the siege party.

Once the failure is made, most of the people who died in the crypt will be terrible: they are suffocated by the burning of sulfur. Before death, they pinch their necks and try to breathe, and scratches are covered with their faces and necks. This tragic situation is a huge blow to morale.

But even so, the various data on the acupuncture are necessary for the staff to prepare. The staff officer only needs to calculate how many people will die, how many people can fulfill their intentions, and there is no need to consider cruelty and morale, which is what the coach needs to consider.

The staff members of the cave attack were responsible for the planning of the cave attack, and naturally there were other things to be responsible for the rest of the situation. The war was imminent and orderly.

And the soldiers were just waiting for the order to be issued.

…………

Outside the camp, several Ichigos wore witch costumes with Chu and Si characteristics, high white hats, and pure black flags, gradually approaching the city wall.

There was no gunfire on the city wall. This pure black flag originated from a suggestion put forward by Si Shang after the Heze Alliance War Law was formulated four years ago: to organize an absolutely neutral team of doctors, and treat them regardless of the differences between the princes.

However, all the princes refused at that time because the Mohist infiltration into various countries was already very serious. How could it be more than a "neutral" organization that was justified in various countries?

Although he refused, the Mo family obeyed it himself, and the nobles in the city knew the meaning of this flag and those strange witch costumes.

Since both sides are fighting for righteousness, the new meaning of the Mo family is to save the people of the world, and the old meaning on the opposite side is to fight against the nobles in war, so when these Mo people approach the city wall, a rope was put down.

The man who climbed up the city wall with a rope was searched and escorted to his father Yue Ling.

Mozhe spoke in the standard Shangqiu dialect, and the emperor's father Yue Ling asked coldly: "You are also a native of Song, but now you are enemies of Song, which is ridiculous."

The Mo was not willing to be outdone, and also said coldly: "The Song Dynasty is still here. According to the old rules, the princes have a country and the officials have a family. Those who regard the family as a country are usurped. With the Mo family's righteousness, the Song people are Qi people, Yue people are Chu people, and all the people of Xia people, and the nine provinces are the same. How can there be any difference between Song and Chu?"

The emperor's father Yue Ling was too lazy to argue with the Mohist, and knew that the Mohist envoy wanted to speak sharply, but he was afraid that if he continued to fight, he would say many unnecessary words, so he asked, "Why did it come from?"

Mo said: "There are still women, children, elderly and weak in the city. If the war occurs, there will be damage. Therefore, please let them go out of the city to make the whole Mo family the meaning of "the Mo family."

The emperor's father Yue Ling laughed and said, "I have heard that if someone wants to kill someone, he will not torture the person being killed when he kills, but will kill him with one sword. When asked, he replied, "It is kindness, and he cannot bear torture. This is false benevolence and righteousness."

"If the Mo family really had such kindness and compassion, how could they attack me? If they did not attack me, how could they be killed or injured? In the past, Mozi said that he was not attacking, and that was contrary to the Mo family's righteousness. He was wary and good at attacking. Now that he wanted to attack me, he also pretended to withdraw women and children. Isn't this ridiculous kindness?"

The Mozhe was too lazy to refute these words and said solemnly: "According to the orders of Juzi and the Mo family Qixiu, if you do not follow this matter, it will be considered a war crime. In the future, this crime will be punished by a gun. Please be cautious."

The emperor's father Yue Ling laughed and said, "Look at the corpses hanging outside, why don't you tell me if you want to be guilty? Could it be that according to your righteousness, can my sin be exempted from shooting? Tian Wu simply slaughtered Wucheng, and was sentenced to shooting. Now I am afraid that I will also be responsible for the people who fight against the people. If that is the case, why should I be afraid?"

"Let's just say something, this won't convince me."

The Mozhe said in a deep voice: "A war is over. Once the city wall is broken, even the old and weak in the city can still be repaired. Do you think it can be kept?"

The emperor's father Yue Ling understood that if the city wall really collapsed and the old and weak needed to repair it, it was actually not far from breaking the city.

He was also open-minded at this time and shook his head and said, "No."

Mozhe said again: "The city is held in a stable manner and it is necessary for food. If you don't give them what you eat, your family will inevitably be resentful. If you give them food, you may only be able to eat for half a year. Letting women, children, elderly, and weak will be beneficial to you."

The emperor's father Yue Ling sneered: "The Mo family's debate skills are indeed different, but I can't believe you. If you do this, it will definitely be beneficial to you. If you only say it is beneficial to me, you still cannot convince me."

The Mo said, "Of course it is beneficial to me. Benefit, righteousness, for great righteousness, is the greatest benefit of the Mo family. The people are innocent, they should not die, and rescue them is in line with our righteousness. If we do what suits our own righteousness, it is the greatest benefit."

"Didn't you hear that Zi Han does not accept jade? Everyone in the world regards jade as treasures, so I feel strange. Why doesn't Zi Han want jade? But Zi Han believes that integrity is the real treasure, so he gave up the treasure in the eyes of others for his own real treasure. This is the same principle."

"For our Mohist family, the people's health and wealth are free from the three problems, which is what we think is the most precious thing, so we suffer from wind and rain, which is difficult to understand in the eyes of others, but in fact we are pursuing our own treasures."
