Li Mu is a descendant who has never fought in the wars of the Tang Dynasty and has no experience at all. But don't forget, he's a game designer. When designing the game 'The Legend of the Tang Dynasty', in addition to data balance, he also participated in the construction of the gang territory system.

One of the most important ways to play in the gang territory system is the siege between gangs. In order to make the game more interesting, Li Mu worked a lot of overtime at that time and read a lot of historical materials. The siege warfare in the Tang Dynasty was still very simple, and it was roughly divided into three schemes, one was against the city gate, the second was against the city wall, and the third was against the people on the city wall.

For the city gates, use 'rush carts'. Also called "Linchong" or "Opposite Tower", it is a kind of siege tower that is armored, that is, it destroys the city wall and city gate with the force of the collision, and the simplified version is a giant log. To put it bluntly, it is to hit the rammed city walls and wooden city gates with its own weight acceleration, and the city gates are smashed, so that the army can rush into the city.

For the city walls, a bed crossbow is used. Also known as the "Eight Ox Crossbow", the arrow takes the hard wood as the arrow shaft, the iron piece as the feather, the size is like a javelin, it is a veritable big killing weapon, this thing is quite spectacular when it is launched, the arrow can cross two horses, and the huge impact force can nail the arrow directly into the city wall. During the volley, hundreds of "javelins" were driven into the walls, allowing the siege soldiers to climb up.

For those on the city walls, bows and arrows are used. During the Tang Dynasty, both foreign races and Tang soldiers shot good bows and arrows. When attacking a city, the bow and arrow are an indispensable weapon, the defender can shoot from the top down, and the besieging side needs to throw, shoot the arrow into the air, and then fall down, under the action of gravity, the lethality is greater than a direct shot.

In addition to the above three tactics, there are also the most basic, such as grappling hooks, ladders, etc., these have no technical content, and they are completely desperate. Often, it is cheaper to defend a city than to siege it. With the strength of both sides equal, and the defenders of the city without food and grass, it is almost impossible for the besieging side to succeed. Li Jing's army only used 3,000 elite cavalry to break through the Dingxiang City, in addition to the factor of brave soldiers, the main thing is that the Turks are not good at defending the city, the Tang army suddenly attacked, caught off guard, did not know how to deal with it, and was broken the city.

Li Mu dared to come back, not because he suddenly rushed to the head and committed the second disease. Instead, he fully considered various objective conditions and felt that he could hold on before he came back. Previously, when Li Siwen wrote a letter to Li Ji, he usually received a reply in three days, that is, the one-way journey was almost a day and a half. Li Ji sent a letter and said that he had found the trace of Princess Yicheng and would definitely send someone to chase him. Even if he found it near Lingzhou, the journey would only be a day and a half. In other words, the time available for Princess Yicheng to attack the city is no more than one day. When Li Ji's soldiers arrived, she wouldn't have any chances.

Half a day has passed now, and Princess Yicheng's men and horses are still nowhere to be seen. Li Mu's heart has been relieved of most of it, even if Princess Yicheng comes now, as long as he can hold on for a day, the problem will be solved.

Now the question is how to hold on to this day.

Li Mu analyzed that since Princess Yicheng gathered hundreds of remnants after the Turkic camp was broken, it means that she could not have siege equipment. In other words, she can't have 'rushing cars' and 'bed crossbows'. But there is a dense forest nearby, and if Princess Yicheng sends someone to cut it down, make it into a ladder, or simply find a giant tree to hit the city gate, this kind of thing can still happen.

In response to these two possibilities, Li Mu first arranged for all the craftsmen to demolish the houses at the city gate and use bricks, stone and wood to build the city gate to death. No matter how much you hit it, it is impossible to knock the gates open.

As for the ladder siege, Li Mu also has a way to deal with it. Among the craftsmen, he found a few people who could strike iron, and let them make a lot of 'iron thistles', this kind of thing doesn't need any drawings, in short, how to prick people, how to dodge, how to dodge. All the iron ingots left of the old iron head were smelted into thistles and iron thorns, and the masons went into battle together and set them all on the city wall. In this way, it is impossible for the Turks to climb the wall when they attack the city.

In addition, the remaining bricks and stones blocking the city gate, Li Mu mobilized the people to move up the city wall together. When the Turks attacked the city, this was the 'wooden cannon stone', which did not require much effort, just pick it up and smash it.

In addition to these, Li Mu also fully considered the possibility of the city being broken. So he ordered his men to dig a shallow pit about half a foot apart in the middle of the streets of the city, the size of a bowl. This is what he learned from the TV series, Li Mu vaguely remembers that this kind of thing seems to have this 'trap in a movie', if the horse falls into this 'trap' when running, the horse's legs will be broken immediately. At that time, people were lying in ambush on both sides, holding spears, falling down one and stabbing one to death, without even having a chance to react.

Tossed around until dawn, basically all the preparations were arranged. Li Mu stared at a pair of dark circles and inspected the four city walls, feeling that the preparations were quite sufficient, even if Princess Yicheng came to attack, there were only a few hundred people, as long as she didn't go out of the city wall to fight head-on, she couldn't attack it. Even in the worst-case scenario, a day or two is not a problem.

Li Mu ordered people to set up a stove on the edge of the city wall to cook, the food in Dingxiang City is still enough, after all, the population of the city is only six or seven hundred people, judging from the current grain stock, it is not a problem to insist on half a month, the war is imminent, every stove is dry rice, there is no thin at all, everyone is tired for a night, and they have to eat enough to have the strength to resist the enemy.

"After eating, lean against the wall and take a break. Rest assured, as long as we survive the day, we will be fine. Everyone put their hearts in their stomachs, reinforcements are already on the way! ”

Li Siwen shouted by the neck, but there were few responders. The tension before the war, the fear of an unknowable future, has taken over the hearts of the people.

Li Mu dragged Li Siwen, handed him a nest head, and said, "Save your voice, if you really fight, when you shout." Li Siwen took the nest head and bit it, at this time he didn't think the nest head was coarse grain, and swallowed it into his stomach. He secretly glanced at Li Mu, saw that his expression had not changed, and said, "You're not worried at all?" ”

"Worried." Li Mu swallowed the nest in his mouth and said, "But it's useless to worry, the important thing is that I don't believe that I will die here." ”

Li Siwen laughed and said, "Where did you get your confidence?" It's like having been in a war. ”

Li Mu didn't explain, he couldn't say that he felt that he had a pig's foot halo and couldn't die so ordinarily. The two of them were about to return to the yamen, when they suddenly felt the ground tremble, and hurriedly dismounted and climbed up the city wall. I saw smoke and dust billowing from the west, and the sound of horses' hooves was like muffled thunder, not to mention thousands of people and horses. The nest in Li Siwen's mouth fell to the ground, and he looked at Li Mu sluggishly: "My father said that there are only a few hundred people, where did this, so many people come from!"

"Where do I know where to go!" Li Mu raised his leg and shouted: "The people are coming to the door soon, why don't you hurry up and beat the drum!" ”
