The nobles of Qi are no strangers to Jizi Korea, Qi imports Wenpi and Yufu from Korea, and maritime trade has also appeared, the essence of Jizi Korea is near the Liaohe Plain in later generations, and there are many merchants in Qi who transship goods from there to make a profit.

On the Korean Peninsula, some Qi merchants were no strangers to passing through Changdao through Laidi, along Changdao to Liaodong, and then from Liaodong along the coastline all the way to the southern part of the Korean Peninsula for trade.

Tian Wu knew that this was the last path that the strategists had found for themselves, and it seemed to be the only feasible path after failure.

After bowing down and thanking him, Tian Wu thought to himself: If you go to the bitter cold land and hide your name, although the family knowledge of the nobles is enough to become famous, isn't the ancestor of your family also accumulated more than 100 years in the Qi State after the fall of the Chen State?

If it is really pushed to that point, this is the only way to go.

The dead soldiers around him also expressed their willingness to follow him when the time comes, and they will never turn their backs on him for the rest of their lives, as for those nobles who want to follow him in rebellion for more benefits, it is obviously impossible to take this path.

Tian Wu, who was still young, could not have experienced what the sorrow of leaving was.

But when the strategist said today that if he didn't succeed and fled to Jizi North Korea, Tian Wu could feel the mood of Jizi passing through the palace and singing about leaving the country.

Thinking that there might really be such a day, Tian Wu couldn't help but tremble and sighed.

"Heavens! Who is this? ”

O Emperor of Heaven, who forced himself to think about going away?

After singing, everyone mourned, Tian Wu stopped this uncontrollable emotion, and after tears, he began to think about the future again.

A few days later, the army assembled and began to spread out in this small area.

Tian Wu only said that he was infected with a rash and could not see the wind, so he hid in the car to command, and the generals could only talk to him through the car window.

The main force was concentrated in Binh Duong, with Binh Duong Eup as the launching point of the attack and the concentration of troops, as a bridgehead for the attack on Win Eup.

The troops of the Fei nobles and a part of the Qi army were stationed in Dongmu to guard against the outflanking of the Ministry of Public Metallurgy.

A part of the elite Linzi soldiers and Tian Wu's private soldiers, on the grounds of guarding against the outflanking of Gongzaoye, were transferred to the vicinity of Dongmu, and Gongziwu had already made peace with the private soldiers he wanted to bring back to rebel and seize power, and the ones who remained in the army to command were his advisers.

Once the great war around Yingyi broke out, Gongzi Wu in Dongmu could quietly leave Dongmu, take advantage of the situation that the war attracted the attention of the Mo family, fled eastward, crossed Yishui, reacted on the Linzi side and gathered troops to prepare for a coup d'état, calling on the nobles to defend Linzi.

…………

Yingyi, since it was seized by the Mo family, has been repairing the city defenses, and the two previous tentative attacks of the Qi army were easily defeated.

More violent land reforms and a large number of fugitive nobles left the vacant land, making it easy for the Mo family to gain a foothold here.

Within 30 miles of the city, the support of the people can be regarded as a pot pulp.

The people of the cities were mostly farmers, which was easy to organize and publicize, and although the distant villages were still difficult to control, the urban population was the foundation of a country at this time, because no country could control the countryside, nor could it obtain enough taxes and soldiers from the countryside.

Located along the Wenshui coast, it is also convenient enough to transport grain and grass from downstream.

The territory of Qi occupied by the Mo family today is roughly a triangle.

With Mount Tai as the base, Lucheng, Pingyin, and Yingyi are not very far from each other, and the water system is developed at this time, so that Yingyi has accumulated enough grain and grass to guard.

Especially in Liangfu and other places, as the logistics supply storage place for the Linzi Army to go south, there is enough food in the granary to not only meet the needs of the righteous teacher, but also to learn from Nangong Shi Juqiao Fa Su, but also enough to use grain as a salary to raise people to build the city wall, get enough good reputation, and do not force labor.

Even if the city wall was built in a short period of time, it was impossible to be like Pengcheng or Peixian, where enough cushions were dug to prevent shelling and the walls were densely packed.

However, the Mo family itself has the skill to defend the city, and has its own set of systems, combined with geometry and the summary and development of these years, it is enough to turn Yingyi into a difficult city to attack in the short term.

At the head of Yingyi City, the commander of the 2nd Division was using a clairvoyant mirror to observe the city wall that twisted and formed a protruding acute angle, and there were many local farmers busy on the city wall.

The herald ran over and said: "Division commander, the sappers are here, and the commander has sent all the cannons that attacked Pingyin at the beginning, a total of more than 20 heavy bronze cannons, and the sappers are in a hurry to build the fort." ”

The commander of the second division nodded, thinking of the order conveyed before, and said in his heart: "Shi Shuai means let us defend first and see what the Qi people are going to do." Zi Mozi thought that such a city was enough to defend an army of 50,000, but now I have artillery and renovated the city, and there is no problem in holding it. ”

He was also puzzled, and couldn't figure out why the Qi army would desperately fight this inevitable battle, but then he thought that if he was Tian Qing Tian Wu, the matter had come to this point, and there was indeed no way to break the game.

The Mo family has defended a lot of cities over the years, and they are good at attacking and defending cities, and it is precisely because Mozi is good at attacking cities that they can defend cities.

Confidence is sufficient, the whole division of the second division is not worried about the upcoming battle to defend the city, the first battle of Nanjishui and the third division became famous, and now all divisions are holding their breath in their hearts.

Coupled with the glory of the Battle of Nanjishui, it brought high morale, but for the senior officers, they still cautiously adhered to the attitude of contempt and invincibility against the enemy.

The art of defending the city is skillful, and various laws and regulations for defending the city have also been promulgated, and there are special people in charge of it, so that everyone can perform their duties, and the lord will be much easier.

This is the first time in these years that the Mo family has arranged city defenses in a formal war according to the city defense techniques accumulated by the Mo family since the Mozi era.

The Mohist city defense technique is systematic, and there is a certain subconscious geometric foundation in the Mozi era, and after 20 years of development, this systematic city defense has become more and more perfect.

Zi Mo Ziyan: Rate ten thousand families and the city is three miles, it is advisable to keep it.

Win Yi is also the city of ten thousand households, three miles of the city, the most suitable for defending the enemy's attack.

Zi Mozi said: The guest attack is successful, the crowd of 100,000 things, the one who has not attacked the four teams, the upper technique is 500 steps, the middle technique is 300 steps, and the lower technique is 50 steps. Those who do not take more than one hundred and five steps, the master is beneficial.

This is to say that the besieging side, plus the logistics and heavy auxiliaries and other nearly 100,000 troops, if you want to attack the city, you can only deploy four teams at most, and these four teams are at most 500 steps wide, about a front of about 500 people, forming waves, it is impossible to rush up, this kind of siege is the command of a famous general, but in view of the narrowness of the battlefield, only four teams can be deployed, and then it will be chaotic.

Therefore, the defending side does not need to consider how many people there are on the opposite side at all, but only needs to allocate the number of people according to the established countermeasures, and even if there are 100,000 people on the opposite side, it is impossible to rush up in a swarm.

Zi Mo Zi said: All foreign roads can be fortressed to make it difficult, and the most harmful ones are to build three pavilions, three corners of the pavilion, and weaver girls, so that they can be rescued.

The so-called Weaver Girl means to deploy the Acropolis fortress in the shape of the Vega Star in the sky. As we all know, Vega and the two bright stars nearby form the summer triangle, which Mozi means means that the Acropolis fortress should be arranged according to the triangle, that is, the zigzag configuration, so that they can support each other.

Combined with the concept of "walking walls" proposed by Shang Mozi, the basis for the rational defense of the city in actual geometry already exists, and when the gunpowder comes out, it is easy to form a professional fortress defense system.

Zi Mo Ziyan: The city is the Jue Cave, three feet down, wide outside, five steps one. Jue Cave is large and tolerant, the high one is six feet, the lower one is three feet, and the sparse number is suitable for it. People are good at borage, and they are five knots long. Kou is under the city, listening to the sound of drums, burnt endive, double drums, and the inner borage is in the cave, and the outside is illuminated.

As the first person in the history of optics, Mo Zhai naturally used optical knowledge in the city defense technique, and the problem of small hole imaging made Mo Zhai determine that the light was propagating along a straight line, so he wanted to build a "Jue Cave" at the head of the city.

The so-called Jue Cave is to make a hole under the city wall, and the hole is aimed at the city, because the light spreads along a straight line, so when the enemy attacks the city at night, the firewood of Jue ** will be lit, because the hole is facing the outside, so these fires will shine outside.

And lighting torches at the head of the city, which is strictly forbidden by Mo Zhai, lighting torches at the head of the city is equivalent to being a live target for the people under the city.

With the design of the Knight's Cave, it can be ensured that the enemy will not be able to see the layout of the city, but the people in the city can see the deployment of the night attack of the besiegers under the city with the help of the fire that spreads in a straight line.

As for the so-called city-defending machinery, such as the canal and the chariot, the stack, the building, the Jiegao, the Lianji, the long axe, the long vertebrae, the long zi, the distance, the flying rush, the county □, the criticism, the transfer machine, etc., some of them were directly replaced by gunpowder mines and artillery without any lag, and the rest were also improved.

Now standing in the east of Mount Tai, south of Linzi, and west of Yishui Yimeng Mountain, although the construction is not perfect, but it is the first time in these years that the princes of various countries have to face the city guarded by the city in full accordance with the Mohist system and the real Mohist righteous teacher.

The confidence of the commander of the Second Division also stems from this.

The three-mile city wall has been renovated to form a cascading star-like structure.

The outer moat and the moat were within the artillery range of the star-shaped row wall, and the sides of the trench were just below the battery level.

The concepts of "Walking Wall" and "Weaver Girl" are both designed to strengthen the side-firing firepower, so that the trench cannot be used as a cover for the attacker, because there are turrets at both ends of the trench that can be fired sideways, and directly attack the trench, after precise geometric calculations, so that there are basically no blind spots.

Within 300 steps in front of the main gate, there are two simple garrisons, which form a large triangle with the main city behind them.

It seems that these two garrisons are separated from the main city, but in reality they are not, because there is no way to approach the main city without taking the two garrisons.

Insufficient artillery is difficult to capture two garrisons that are completely in accordance with the gunpowder era, and if you only besiege the city without attacking it, it is equivalent to suicide: the triangle formed by two forts and one city will make the Qi army completely die in this triangular structure.

Except for gnawing with teeth, or taking Yingyi, it is impossible for the two garrisons to be cut off from support: because there are cannons in the city, it is possible to block the distance between the fort and the fort for three hundred paces, and some heavy bronze cannons can also cross the distance of three hundred paces to attack the fortress directly.

The moat near the city wall, according to Mozi's experience in defending the city back then, is densely covered with bamboo sticks, and as Mozi said, the front is tilted forward and the back is tilted backward, ensuring that the attack or retreat will definitely be stepped on.
