Most of the early human fortresses were combined with settlements and developed from settlements, and there were fewer cases of Yang Jiao directly moving out all the original residents of Hewandi and occupying the original villages to rebuild them.

Yang Li's renovation was purely for military purposes, and in order to set up cross-fire between the arrow towers, he would even sacrifice some of the castle's internal space.

This kind of thinking was applied on a large scale in Renaissance Europe, and it was embodied in the bastions – very few were broken by a frontal assault, because no matter which direction they attacked, the attackers would face at least two or even three muskets on the walls, with nowhere to hide and heavy casualties.

This was the development of the fortress from civilian to military.

Yang Jiao is faced with a classical fortress, which is built on the mountain, essentially a settlement, but only in a few places with wooden fences, the rest of the positions are earth and stone piles about two and a half meters high, can stand people, there is no future jagged city wall, just a simple earth and stone bunker.

"Does anyone see what?" Yang Li asked.

Everyone stared at the map and talked about it, and there were many warriors who had learned the contour map, although they had not received systematic tutorials, but they were better than the number of people.

Yang Li provides a good atmosphere for everyone to discuss, once the number of human beings comes up, work together, there are few problems that cannot be solved, the so-called meeting to solve the problem, is that everyone gets together, everyone speaks their own thoughts, everyone can listen.

Whoever has a good idea can be discussed, whose idea is highly feasible, with the wisdom of everyone, where there is a problem, one person can't see it, ten people can't see it, but a hundred people look at it together, how can they see a clue.

Of course, there is a prerequisite, these 100 people are all insiders in the industry, and they are all fighters who have fought in battle.

"The terrain of the Xiling camp is higher, if we attack from the steep side, everyone will move slowly, and we have to guard against the stray arrows and flying stones halfway, so we must not be able to go up here!" Someone pointed to the location where the contour lines were dense and began to use the method of elimination.

Another person immediately objected: "What's wrong with the steep slope, don't we have more time to climb over the mountains, set up a shield, and climb it for you in minutes!" ”

"Didn't you hear the big boss say that you should reduce casualties and attack from the most effective position?"

Huya snorted and maintained discipline: "Don't be noisy, the one who said to avoid the steep slope, say the direction you want to attack." ”

"Of course, it is attacked from the front, although the main gate is concentrated by the enemy, the terrain is flat, and our array can also be opened, according to the combat effectiveness of everyone, it is not to climb up and slash and slash."

Yang Jiao smiled and was about to speak, only to see a few more people come out and say that it is laborious to climb up the steep slope, but the distance is closer, instead of entangled in the main gate for a long time, it is better to seek wealth in a dangerous situation, and try to break through the projected fire on the steep slope.

If Yang Jiao had 1,000 people, he would directly surround the Xiling camp and attack, but the current situation is that there are more than 200 soldiers inside, plus the women and children who participated in the battle, how can it be counted as 300, and more than 200 soldiers on his side, although they came to attack the city, in fact, the number is small, and they can only pick a few positions to focus on breaking through.

So everyone didn't see the key to the siege, Yang Jiao directly drew two lines on the map and analyzed them one by one.

The main gate of the line, it seems to be flat and the risk is small, in fact, there is a problem, when attacking, you will encounter an arrow stone blow on a platform on the inside of the city gate - the Xiling camp is a step-by-step rising landform, which is a little similar to Diaoyu Mountain, that is, there is a layer of high ground inside.

On this level of heights, the defenders could arrange archers to cover the positions in front of the gates.

So Yang Li marked an arrow here, representing the direction of the bow and arrow javelin: "This is a frontal injury, maybe you will think that you have a shield in your hand, it's okay, but you are looking at the contour line of this position There is a gathering, may I ask what this is?" ”

Several contour lines are close together and glued together, and there are several short vertical lines of vertical contour lines, which are the hallmarks of the cliff.

"Okay, let's stop looking at the map, look up at the main entrance of the enemy camp, and the view is wide, right? But if you look to the right, what can you see? Yang Li motioned for everyone to separate and cast his gaze in the direction of his finger.

There is a steep protrusion on the hillside of the hillside, which is located on the left side of the walled gate, that is, about twenty paces to the right of the attacker, forming a small horse-faced structure, the so-called "horse face", which refers to the protrusion on the medieval city wall, which was used to guard the sectional wall.

And this cliff happens to be a natural "horse face", which is similar to the arrow tower arranged by Yang Li in his own fortress, when the attacking troops approach the city gate, they can launch long-range strikes that are difficult to block from the side.

Most humans are right-handed, so they usually hold a shield in their left hand, and once they face an arrow from the right, it is difficult to block it with a shield.

So Yang Li added another arrow to the map, pointing from the cliff to the walled gate: "So you will face arrows in two directions, and you will have to deal with the warriors on the earthen wall of the main gate, which is a dangerous job." ”

A good attacker should be good at discovering the weakness of the fortress, this weakness is not the literary works of those city walls in disrepair, the defenders go to prostitution and drink, etc., we can't pin the hope of victory on the stupidity of the other side, although the opponents we are currently encountering, such as the eldest cousin, they are indeed stupid.

Since it was the first time to conduct a military class analysis, Yang Jiao directly stated the point of attack.

The location of the siege is the steep slope that someone just mentioned, and the earthen wall facing the steep slope is in the shape of an arc.

Although the math teachers had been talking about what circles were the most beautiful forms in nature and could be applied to fortifications, the arc-shaped walls would make the defenders suffer greatly from their own families, and the original intention was to expand the area of the settlements within the fortress, but once faced with an attack, the problem arose.

Except for the defenders who were directly facing the attacker's point, the people in other positions could only stare dryly, unable to provide any support for long-range strikes.

Moreover, although the steep slope is steep, there are several arcs in the middle, and these arcs are parallel to the wall, which is simply a natural bunker trench.

Yang Li's attack was launched the next morning, with Hayabusa Wing and Xue Pijiang leading the archers to suppress the main gate, hiding behind wooden planks and firing at the defenders, while other slave owners led their men to attack a section of the steep city wall.

Huya didn't join the attack, because everyone was unanimously opposed, saying that if he came, none of us should take credit from him, and after the battle, the Delta Swamp would be divided into him, which was not fair.

Yang Jiao wanted to say that even if he had the greatest credit, I wouldn't go out, but I was very short of bodyguards, but looking at the eyes of the slave owners who were eyeing the burning, killing and looting, I thought that I couldn't break the rules, in this case, the hero units should go to the main gate to paddle and mix dkp.

The offensive battle on the steep slope encountered a small setback, and it turned out that the chief of Xiling saw the movement of the Los Angeles soldiers from a high place, and led the elite to intercept and kill on the slope.

The chief of Xiling was eight feet long, with a tiger's back and a bear's waist, holding a long-handled sledgehammer, and his arms had the power of five oxen.

The slave owners retreated, even if they were veterans of the riverbend, they were still overwhelmed in front of the high-end warriors in ancient times, and threw a few corpses of slave soldiers on the wall, and retreated by themselves to rest and reorganize.

Yang Li said don't be stunned, everyone, we are divided into five teams and take turns, no matter how brave the chief of Xiling is, there are several people, we will cooperate and win.

So four waves of attacks were organized, and when he went up for the fifth time, Yang Jiao was anxious, and he also carried his shield, thinking that the chief of Naxiling had reached the limit and was unable to fight again, but who expected that this indigenous leader still had the strength, and smashed over the guard boy who was blocking Yang Jiao in front of him with a hammer, and the stone hammer quickly enlarged in his eyes, roared, and hurriedly dodged.

Hula, dodged, but the chief of Xiling was stunned and punched over, knocking Yang Jiao to a stagger, and then the sledgehammer fell on his head.

It's broken, it's broken, it's not going to be a concussion, so how much is the ransom worth of my lord of Los Angeles...... Yang Li had already prepared for the worst in his heart.

The fist had not arrived for a long time, and Yang Li suddenly remembered that there was a hairy girl behind him.

When I looked back, I saw that the girl had climbed to a mound a hundred paces away, half-kneeling on the ground, and holding a big sniper in her hand.

"Uhh

Chief Xiling never had a chance to throw another punch, only to see a white light slash through, and the chief's head exploded like a watermelon, and then the body shook a few times and slowly fell.

Hey, I'm going to practice siege techniques for everyone, you're embarrassed to kill the boss with a shot with an artifact, and let others eat the soil!

Yang Jiao was speechless in the face of the corpse, what kind of surrender, binding, etc., all came to naught.

As soon as the slave owners in the back saw that the enemy chief was killed, they immediately beat the blood, rushed up, picked up the axe and spear, and joined the team that broke the city without hesitation.
