A few days later, envoys and officials from Wei, Qi, Han, and Chu arrived at the front, escorted by a group of soldiers, and the front line was already busy.

More than 20,000 second-line soldiers recruited from Pengcheng were digging breastworks and paving roads, and a barracks surrounding Dangshan City, outside the pitiful artillery range of Dangshan, was half completed.

The observation group composed of envoys was arranged on a dirt hill 800 steps away from the moat of Dangshan City, which was also the front-line command post of the Battle of Dangshan.

These envoys were sent semi-compulsorily, and of course they also had the heart to see what the combat effectiveness of Sishang was, so as to make a judgment and influence whether the prince would send troops.

A deputy envoy of Wei looked at the two hot air balloons of cloth and patent leather floating in the sky, full of curiosity, and said to a Korean deputy envoy beside him, "This Mo family's method of attacking the city looks completely different from before, but in fact, if you think about it carefully, it is no different." ”

"In the past, we had to build sheep mounds and watchtowers to observe the situation in the city. Nowadays, only the watchtower has been replaced by a flying sphere. ”

"In the past, it was necessary for those who were deaf and discerning to stand on a high platform to observe the situation in the city, but now they are just replacing those who are deaf and discerning with clairvoyants."

"In the past, the siege of the city wall was to rush the chariots, but now the bronze cannon is used; In the past, you used to use a ladder to climb, but now you ...... It's still a ladder, hahahaha. ”

The deputy envoy of South Korea said with a smile, "The words of the slang are appropriate, comprehend the will of heaven, and change the world." If you think about it, it doesn't change much. As you said, there were feudal kings in the past, and now the merchants of the Song Dynasty are also the kings of the plain seals, they can't change the world, but they just change the people who benefit from the world, with their righteousness. ”

These people spoke freely, and the soldiers in charge of guarding next to them were all internal security troops of the Supervision and Inspection Department, silent, with a serious face, and turned a deaf ear and blind to the words of those people.

Next to these people, there was a telescope, and a few people picked it up and looked at the second-line soldiers who were busy digging pits and building camps in the distance, and said with a smile, "The Mo family is attacking the city, and they like to attack the cave the most, and the ink is black, I think they are like a group of rats, digging pits everywhere." ”

Although there is some ridicule, this seemingly extremely simple and even somewhat obscene zigzag tunneling tactic has proved invincible in previous actual battles.

It's just that countries have learned little about the essence.

Some things seem easy, but the real essence is not so easy to learn.

…………

In the tent of the staff headquarters in the camp, several officers were drawing a more accurate map of Dangshan City's defense through the hot air balloon observation of the situation in the city.

The rest of the people calculate the optimal delivery ratio by the allocation of the artillery at the head of the city, the angle of the city wall, the width of the city wall, and the angle of the unfolding.

A staff officer took a protractor and a compass ruler, stared at the map and calculated for a while, and then said to the people around him, "The left side here is a river fork, which is not suitable for digging. ”

"If we dig a cave here, the distance is not enough, we have to advance to a place two hundred steps away from the city wall before we can use the cave attack."

The young staff officer skillfully drew a circle on the map with a compass and dug a crypt to attack, which was a common means of siege.

It is not the zigzag outside that exposes the trenches used to assemble and approach the city walls, but the means of directly digging tunnels to approach in the "Preparation of Caves".

Tunnels are not dug randomly.

Because of Sishang's years of experience in digging pits, mining experience, and previous experience in defending the city, this kind of crypt close to the city wall can only dig 300 steps at most without vents.

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

As for what kind of terrain can be dug without seepage, how close do you need to dig to dig it...... This is where the staff headquarters on this side of Sishang is left.

Dig a pit and you know that the crypt can fight, the question is how to dig it, how far to dig it, where to dig it, and how to dig it.

The Dangshan Castle on the drawing in the hands of the young staff officer was like a hedgehog with spines blown up, with a total of sixteen raised horns, that is, sixteen concave surfaces.

The distance between each convex angle is about two hundred paces, which is exactly the maximum range of the bow and musket, and attacking any concave surface will inevitably face projectile blows from both sides.

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

This is the biggest difference from the Sifang City before the gunpowder age, although before this Mozi proposed the idea of walking walls and horse faces with bows and crossbows, but it was not perfect.

Dangshan is not a city wall of the rammed earth cloud ladder era, it is the first formal gunpowder age city defense outside of Sishang, and it is also the confidence of the imperial father and his family that they can resist Si for the first half of the year and make various countries interfere.

A large amount of stone in the Dangshan area was used for the construction of the city wall, and there was a heavy masonry slope outside, surrounded by a moat about five steps wide, and the inside was stagnant water, and it was very low, which could not be solved by cutting off the upstream or draining it.

The means of siege are ever-changing, just as the deputy envoy of Wei is concerned, in fact, it is still those things in the past, and the method of siege has been summed up by Mozi before he joined the Mo family, and there is no change in the overall strategic thinking, what has changed is only the tactical change of new weapons.

The task of the staff officers is to devise all possible means of attack, do a good job of the work on the map, calculate the allocation of manpower, fire support, artillery arrangement, etc., and finally let the commanders make a decision and choose the method of siege.

Cave attack is only one of the methods, and unlike the previous cave attack, today's hole attack is mainly to dig a pit in the foundation to bury gunpowder, so that if successful, it is more efficient.

However, it is also the most brutal for the besieging side.

As early as more than 20 years ago, when Mozi was defending the city, he proposed more brutal counterattack methods for the means of attacking the crypt.

This includes but is not limited to irrigation, smoke with skins, suffocation by burning sulfur, and poisoning by poisonous weeds.

By using the change of the water level of the well and the means of listening to the sound of the pottery urn, you can judge the direction of the attacker's tunnel, and if you make a targeted counterattack, it will be a great blow to the morale of the besieging party.

In the event of defeat, most of the people killed in the crypt were horribly suffocated by the burning of the brimstone, pinching their necks to breathe before dying, and scratching all over their faces and necks, which was a great blow to morale.

But even so, the various data of the cave attack must be prepared by the staff officers. The staff officer only needs to calculate the approximate number of people who will die and how many people will be able to accomplish the intention, and there is no need to think about cruelty and military morale, which is what the commanders have to consider.

The staff officers of the cave attack are responsible for the planning of the crypt attack, and naturally there are others to be responsible for the rest of the aspects, and the big battle is imminent, in an orderly manner.

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

…………

Outside the camp, several ink warriors dressed in witch costumes with Chudi and Sishang characteristics, wearing high white hats and holding pure black flags, gradually approached the city wall.

There were no shots on the city walls, and this pure black banner originated from an idea put forward by Sishang four years ago after the formulation of the law of war of the Heze Alliance, that is, to organize an absolutely neutral team of healers, regardless of the difference between princes, to heal.

It's just that the princes refused at that time, because the Mo family's infiltration of various countries was already very serious, and it would be worth it to come up with such a "neutral" organization that legitimately operated in various countries?

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

Since both sides are fighting for "righteousness", the new righteousness on the Mo family's side is to save the people of the world, and the old righteousness on the opposite side is that the nobles do not kill envoys in war, so when these ink people are close to the city wall, a rope is put down.

The inkman who relied on a rope to climb the city wall was searched and escorted to the emperor's father, Yue Ling.

The ink master opened his mouth in the standard Shangqiu dialect, and the emperor's father, Yue Ling, asked coldly, "You are also from the Song Dynasty, but now you are the enemy of the Song Dynasty, which is ridiculous." ”

Not to be outdone, the ink man also said coldly, "Song Jun is still here, according to the old rules, the princes have a country, the doctor has a family, and those who take the family as the country are usurped." With the righteousness of the Mo family, the Song people, the Qi people, the Yue people, the Chu people, all the Xia people, and Kyushu are the same, how can there be any difference between Song and Chu? ”

The emperor's father, Yue Ling, didn't bother to argue with this ink man, and he also knew that the envoy of the Mo family wanted to come and speak sharply, but he was afraid that he would say a lot of unnecessary things if he continued to fight, so he asked, "Why did you come?" ”

"There are still women and children in the city, the old and the weak, and the war will be damaged together, so please let them out of the city, with the righteousness of the whole Mo family." ”

The emperor's father, Yue Ling, laughed and said, "I have heard that those who want to kill will not torture the killed when they kill, but will kill with a sword. Asked and answered, benevolence, and could not bear to be tortured. This is false righteousness. ”

"If the Mo family really has this kind of compassion, how can they attack me? If you don't attack me, how can you be killed or wounded? In the past, Mozi's words were not attacking, and the suitability of the Mo family was contrary to the righteousness of the Mo family, and he was warlike and aggressive, but now he wants to beat me, and then he comes to pretend to withdraw the women and children, isn't this ridiculous benevolence? ”

The Mo man didn't bother to refute these words, and said solemnly, "According to the order of the giant and the Mo family's seven enlightenments, if you don't comply with this matter, it will be regarded as a war crime, and this crime will be divided by shooting in the future." Please be cautious as well. ”

The imperial father, Yue Ling, laughed and said, "Look at those corpses hanging outside, why do you want to add to the crime?" Is it not because of your righteousness that my sins can be exempted from execution? Tian Wu was nothing more than slaughtering Wucheng, and he was judged and shot by you, and now I am afraid that I will also bear the burden of the people who stubbornly resist and harm the people. Why, then, should I be afraid? ”

"To put it another way, it doesn't convince me."

The ink man said in a deep voice, "Once the city wall is breached, even if the old and weak in the city can still be repaired, do you think it can be defended?" ”

The emperor's father, Yue Ling, understood that if the city wall 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, shook his head and said, "No." ”

The ink man also said, "The city is fortified, and food is necessary." If you don't give them something to eat, their families will be resentful. Give them food, and you may only be able to eat food for half a year if you could have eaten it for a year. It is in your good interest to let go of women and children, old and infirm. ”

Imperial Father Yue Ling sneered: "The Mo family's arguments are really different, but I can't trust you." If you do this, it will certainly be beneficial to you, and you will not be able to convince me only if it is good for me. ”

The ink man said, "Of course it's good for me. Profit, righteousness, and righteousness are the greatest interests of the Mo family. The people are innocent, they don't deserve to die, and it is our righteousness to rescue them. We do what is in our own righteousness, which is the greatest good. ”

"Don't you hear that Zihan is not subject to jade? The world takes jade as a treasure, so I feel strange, why doesn't Zihan want jade? Ke Zihan believes that honesty is the real treasure, so he gave up the treasure in the eyes of others for his own real treasure, which is the same reason. ”

"For my Mohists, the well-being and freedom of the people from the three calamities is what we consider to be the most precious thing, so we suffer from the wind and rain, which is incomprehensible in the eyes of others, but in fact we are pursuing our own treasures."

"It is for you to reduce food, stabilize the morale of the army, and hold the city, which is your advantage. For us, it is in our interest that the old and weak avoid war and that the people are free from war. To each his own, he takes what he needs, and that's what I hope I can convince you. ”
