The last sentence made Lu Yanggong's face change, he was not worried about the situation of Shangqiu in Luyang City, after all, it was different from the contradiction between the nobles and monarchs over there.

But fearing that the people would be disgusted with war, they refused to defend the city. If you want to ask for the help of the Mo family, you have to consider the conditions of the Mo family.

Direct field confrontation, Lu Yanggong is not confident in defeating the Jin and Zheng coalition forces, he knows his own catties, and he also knows that this time Wei Han will inevitably be attacked by heavy troops, even if he has the courage, it is difficult to say that he can win the battle.

Lu Yanggong really had no choice, so he had to ask, "Is there no other way?" ”

Shi smiled: "You still don't have any illusions. If you really have another way to defeat Jin Zheng in a field battle, why do you have to invite the Mo family to Luyang? ”

"It is impossible for the elite of the Mo family to participate in this defense of the city, and these weapons are also defensive, so it is impossible to participate in field battles."

"Before I came, the giant talked to us about the situation in the world, and he said. If you want to defeat Jin Zheng, you can only defend the city, and your elite will wait for Jin Zheng to lose his sharpness, and then fight with him, or you can be pacified. ”

"If the city can't be defended, Jin Zheng will attack it, and the morale will be great, how can you win?"

Lu Yanggong was helpless, and said again: "If you agree, then we can do this for you to ensure that the people can fight to the death." If you don't agree, there's nothing we can do. ”

Lu Yanggong is not good at this kind of thing, but the Mo family is so talented that it seems that it can be handed over to the Mo family to do.

He didn't know much about the Mo family's methods, and he didn't think about giving such an opportunity to the Mo family, who would benefit the most.

But Shidu had already said something like inviting Gao Ming, and after thinking about it, he had no choice but to say: "In this case, dare not obey your fate?" ”

After agreeing to this matter, he smiled and talked to Lu Yanggong about other guards.

…………

Within a few days, Lu Yang Gong asked someone to prepare those deeds, but they were handed over to the Mo family, and some of the more than forty Mo people who followed were members of the Xuanyi Department, so they decided to do something.

In the past few days, I also talked with Lu Yanggong and others about the route of Jin Zhengruo's attack on Luyang.

At night, Meng Sheng and Hu Feizi sat with Shishi, lit lamps and candles, and did not talk about the destruction of the city's grace, but talked about the preparations for this war.

The location of Luyang City is very special, there is a lake in the west, and there is a string of mountains in the north, and the Jin-Zheng coalition army wants to capture Luyang, there is only one way to go.

In these years, the march was bound to take a big road, and it was impossible to cross the mountains and mountains, and it would be a disaster in terms of the organizational strength at this time.

Luyang is close to the ancient water, "Water Jing Note" said that the water out of Nanyang Luyang County Xiyao Mountain, from the Funiu Mountain, through Luyang, flow to Pingdingshan Yingcheng area.

The Jin-Zheng coalition army wanted to attack the Great Wall of Chu and cross the water, and Luyang was the only way to pass through the western front. Otherwise, you have to go to the first line of Yecheng Fangcheng, where it is too difficult.

And to attack Luyang, it is necessary to cross the Niuqi, advance along the main road, pass through some small towns attached to Luyang, and there is no other way to go.

In later generations, Ruzhou now has many large settlements, such as Huyang, Zhucheng, Herenju and other small towns, these as the border cities of Chu and Han, basically have little resistance.

Only in the northeast of Luyang, Niu Yan City, seems to be able to be used as a defensive stronghold.

Defending Luyang is not a means for the Mo family to defend the city, the Mo family pays attention to defending the city if it can take the initiative to attack and break the enemy's siege as the best policy, resist and delay the enemy's attack and organize a counterattack as the middle policy, and finally defend the city to delay the time until the opponent is short of food and withdraw the army.

Since the above strategy did not work, and because of the topography of Luyang, Meng Sheng and other disciples taught by Mozi almost immediately took a fancy to Niuqiyi in the north of Luyang.

The location here is key, and it is the only way for the Jin and Zheng coalition forces to attack Luyang, and it cannot be bypassed.

Stuck here, the Jin and Zheng coalition forces either divided their forces to besiege the city, and the main force went south for a decisive battle; Either the city must be captured, or the supply lines will likely be cut off.

If Lu Yang Gong can organize troops in Luyang, Niu Qiyi can withstand the attack of the Jin and Zheng coalition forces, and finally when the attacker is tired, Luyang will send troops to counterattack and fight a decisive battle, and there may be a slight possibility of victory.

Shi has no feelings for the Chu State, and wishes that the Chu State would be in a mess, but the chaos must not be in the direction of Nanyang, but to find a way to make the Chu State lose a large piece of land on the eastern front, which is the most conducive to the foundation of the Mo family in Pei County and the convenience of the Mo family to penetrate the Chu State.

Since it is said that he wants to make a decision on the spot and find a way to make the Mo family look sideways again, this battle must show some real skills.

The Mohists' city-defending techniques were indeed ahead of their time, and after learning from Mozi for a while, they found that Mozi may be the first person to systematically put forward the concept of "cross-fire horse wall".

In the monographs of "Preparing for the City Gate", "Preparing the Ladder" and "Preparing for the High Arrival", the concept of "walking wall" has been mentioned many times, which is the so-called horse-faced wall in later generations, or "the concept of star castle in the era of no gunpowder".

Relying on a horse-faced wall that protrudes from the frontal wall is the best option to expose the besieging side to three projectile weapons.

He is not the kind of person who is stupid enough to be inflexible, he also knows the reason why the fortress of the gunpowder age is like that, according to the Mohist way of analyzing the origin and solving the problem, this defense mode of "walking wall" and the "star castle" of later generations can be used now.

The fortress became like that in later generations, mainly for two points.

It is necessary to defend against the shelling of the besieging side.

It is necessary to give full play to the firepower of the defenders.

The problem is that today's attackers don't have artillery.

Then if you rigidly follow the bastion pattern to make it so low, sloping and heavy, you don't know why.

Even in the case of inferior firearms on their own side, building like that is to give the besieging side a better chance to attack, the low city wall is easier to overcome, and in the case of insufficient firepower, the enemy cannot be suppressed by firepower, and it is still necessary to rely on the city wall itself to create certain difficulties for the enemy.

Now that the Mo family can provide some firearms, then it is necessary to give full play to its own firepower advantage as much as possible without considering the existence of "opponent's artillery".

Transform the city from a stubbornly defended turtle to a porcupine that inflicts heavy casualties on the besiegers.

This concept does not need to be put forward, Mozi has already talked about the importance of "walking on the wall" countless times, and the origin of "why we should practice the wall".

Although the concept of crossfire is not summed up in these four words, the connotation is already there.

As soon as Meng Sheng and the others heard it, they understood the meaning of suitability.

In view of the fact that the strategy of resisting and delaying the opponent's attack and allowing Lu Yang Gong to concentrate on elite defense and counterattack has reached a consensus, then how to strengthen the defense of Niu Qi and how to make Niu Qi the focus of the side-eyed firearms of the princes of the world, that is, the focus of discussion between each other.

For internal affairs issues, you can take advantage of Lu Yanggong's promise to organize the people in the way of the city's kindness, and it is also the duty of the Xuanyi Department to publicize in advance with a degree of rewards and punishments.

Meng Sheng said: "You know about the use of these firearms, we don't know much about it. According to what you said, if the besieging side also has artillery, the ox can't hold it at all? ”

Niu Qi is not a big city like Shangqiu, if there is really a cannon on the besieging side, it can be said that it will be destroyed by a bombardment. After the advent of cannons, the city's defense system will inevitably undergo great changes, and after the popularization of firearms, the concept of the wall proposed in Mozi's "Bei Gaolin" and "Bei Ti" and other chapters will inevitably shine.

Shi Dao: "If you want to defend it, you must strengthen the defense of Niu Qi and build a new city wall according to the means of the giant to defend the city." Calculate the position of the wall with nine geometry, so as to ensure that the besieging side can attack on one side on three or two sides, so that they are helpless. ”

After drawing the shape of the Star Castle and explaining, Meng Sheng nodded and said, "This is to give full play to the advantages of firearms." It's just that as you said, the enemy has no artillery, so we don't need to build so heavy, we still have to prevent the enemy from clinging and give full play to the power of firearms. ”

Shi nodded and said: "In this way, in fact, the amount of earthwork is much less than that of guarding against the enemy's artillery." ”

In other words, to abandon the advantage of shelling in the place of the fortress, because it is completely useless at this time.

However, to give full play to the advantages of crossfire, and at the same time according to the main siege methods at this time, some walls should be built higher than the fortresses of later generations, and they should not be so thick and heavy, and they should be thinner.

Before the Jin-Zheng coalition attacked, they should have enough time to repair the city walls according to the new plan.

At the same time, Pei County will continue to transport some weapons over to train a batch of projection troops in the short term, and more elite archers can also join Lu Yanggong's field team.

If a group of rabble can be used to defend the bull and die, it is enough to shake the world, and some of the Mo family's "defensive weapons", "Tianzhi Nine Numbers Geometry" and other things can also arouse the attention of the world.

Shi said: "In this case, I will take a few people to Niu Lang tomorrow." Relying on the geometry of nine numbers, measure the topography of the cowherd and draw the drawings of the city defense. ”

"If it can be successful, the princes will not say anything, and it will also help my Mo family's 'Tianzhi' knowledge to spread to the world. Since the defense of the city can be strengthened with the principles of heaven, then others will naturally be felt to be reasonable. ”

Meng Sheng asked, "What about Luyang?" ”

Shi said: "That's right. Since Lu Yanggong agreed to the city's favor to the people, this matter must be in the hands of the Mo family. How to do it, how to say it...... The Xuanyi Department will give a reasonable explanation, which can not only allow the people to respond to the war, but also spread the truth of the Mo family. ”

"It is difficult to convince the people that there is a degree of reward and punishment. I'm afraid that the people don't trust the nobles, this is not the Song Kingdom, and the people don't know much about the reputation of the Mo family, so they can't just rely on the title of 'Mo family' to make the people feel that there is no need to doubt it. ”

After thinking for a while, he said: "Lu Yang and Niu Qi can both set up a piece of wood in the market. Whoever can resist from one side of the gate to the other will be rewarded with gold and jade. In this way, it will be a sensation. ”

"We also prepared a person in advance, if the people just wait and see, if they don't believe and no one comes forward, we need this person to stand up and do this. If there are people who stand up to resist and leave, let Lu Yang Gong prepare gold, and our hands will reward the people who resist wood. ”

In this way, many laws can be trusted by the people. Even if we leave, I am afraid that within ten years, the people will still remember the name of the Mo family. ”
