"Today's lecture on the offense and defense of the battle. As always, you can ask questions first. Duanfuzi stood in front of the case with a cane, and said in a loud voice.

In the past ten days, Zhizhi Hall has held four classes a day, one class for one hour. The four daily classes are: military, martial arts, political knowledge, and moral education. At this time, it was two o'clock in the morning, when the master was teaching. Xue Ning grew up in the family of eunuchs since he was a child, and he has never been involved in martial arts, these days, every time he asks the first question, and now he is like this, I saw him stand up and ask, "Master, how much is the attacking army, and how is the method of observance?"

Duanfuzi seemed to have expected it, and when he glanced at him, he said, "Dahua armament, the attacking soldiers have six soldiers: guns, halberds, knives, axes, bows, and crossbows, and six weapons such as trebuchets, fire oil, crashes, rushing cars, ladders, and siege towers. The guards have six weapons: thistles, stalks, hooks, wolf tooth slappers, curtains, and shields, deer antler wood, distance horse guns, fishing bridges, gate plates, knife carts, and blade carts, and six things in the horse pit, moat, moat, sheep and horse wall, crossbow platform, and white dew house. ”

"In wartime, how can you attack?" Xue Ning asked again.

"When attacking the former, the primary purpose is to strengthen the army's prestige and boost morale, and to try to injure the enemy without damaging itself; when the trebuchet, spear, and crossbow are used to attack and fire rapidly from a long distance; when the enemy and our armies are approaching, they should then strafe with bows and arrows, so as to kill and wound the enemy in front of them; since the enemy and us have exchanged troops, and the fighters are fleeting, we should kill the enemy quickly, and we can poke, pick, stab, and tease with spears and halberds in front of us, and then use knives and axes to split, cut, cut, and cut in the back. ”

"Master, why is the spear in front and the sword and axe behind?" asked Mei Yuanchen suspiciously.

"The wound of the gun and the halberd lies in the depth, and if it is wounded, it will not stop bleeding and will not stop fighting, and the serious person will have the strength to fight again, and the serious person will have the strength to fight again if the viscera is shattered; the wound of the knife and axe is that it is long, and it is difficult to kill the enemy in one blow, and the wounded by it often has the strength to fight again. In order to kill the enemy, the natural gun and halberd are in the front, and the knife and axe are in the back. Duanfuzi explained.

"Since the killing of guns and halberds is stronger than that of knives and axes, then why should they be equipped with knives and axes?" Liu Shiru was puzzled for a moment after hearing this.

"There is no absolute use of weapons. The halberd is highly lethal, but it also has its disadvantages: it is easy to defend because it is advantageous at the head of the gun, and when attacking again at close range, it is easier to return the gun a little slower to the enemy plane. Although the knife and axe are slightly weaker, the blade is long, and when the enemy is crowded, it is free to chop and slash, and its speed is fast. And once the opponent's armor builds a shield wall, it is difficult for the gun halberd to break through the defense, but the heavy axe can break through its defense. Duanfuzi glanced at everyone and replied.

"Master, if the defense line is broken like this, and the back city is not in danger?" asked Hu Huiming curiously.

"It's not that simple to do defense. The purpose of defense is not to win, but to be undefeated. Duan Fuzi said, "When the enemy army is attacking, the spirit is bound to be fierce, and the first thing is to hinder its offensive. Before responding to the enemy with short soldiers, they often set up thistles on the way of the enemy's army, so as to injure the soles of horses and the feet of soldiers, so that the attack is bound to be slowed down. After the thistle, you can put the antler wood, and there is a hook on the antler wood, and its body is soaked in oil, and the enemy will stop and try to remove the obstacle at this point, and at this time the troops are often gathered in one place, and it is a good time for the defenders to release arrows and kill the enemy. The antler wood has been soaked in tung oil, and the arrows are ignited and shot, and the antler wood will become a fire pile, and the fire will become a sea of fire, and the enemy's offensive can continue? Behind the antler wood, you can set up an iron thistle, and the enemy has just crossed the sea of fire, and most of his thoughts are not under his feet, so how can he avoid it when he is on the march? If the enemy has a large number of cavalry, he can set up a trap horse pit behind the antler wood and iron thistle, and the cavalry is used for quick combat, and its horses must be fast, and at this time set up a trap for horses, and the horse will be killed and injured by a hidden knife if it is trapped in the pit. If the enemy is hindered four or five times in this way, the enemy will be injured when they come, they will be tired, they will be scattered, and the soldiers will be afraid. The enemy, who was damaged, tired, and fearful, responded to the enemy in the front. A crossbow can be applied within 50 zhang, and a bow can be placed after 20 zhang, and then the enemy can be killed or wounded. If the enemy is too far away, the front-line armor should quickly erect a shield wall, and when the enemy comes, he will pierce his spear and halberd in the slit. If the enemy breaks through the defense of the shield armor, the two armies will meet each other in short combat, and the brave and the strong will win, and the cowardly and weak will lose. When Duanfuzi said this, he went to see everyone's reaction, and saw that everyone was surprised.

"Master, with so many ways to resist the enemy, it is really difficult to continue to march forward!" Xia Chengxuan muttered, "I'm afraid that the enemy is not several times larger, and I don't dare to attack the city!"

Duanfuzi said slowly, "Since ancient times, siege has always been a tricky thing in the military road. There were 10,000 troops defending the city, and there were no 100,000 soldiers attacking the city, so it was extremely difficult to break through the city. It is because of the ancient good defense of the generals, but it is difficult to leave a name for future generations, often the name of the people are the siege of the city of the general, that is, the siege of the city is more than ten times more difficult than the defense of the city. ”

"The students have been taught!" Xia Chengxuan stood up and thanked him.

I heard the master say again, "What are the ways to resist the enemy? The fiercest time in the battle is the time of siege." Just because, at this time, it is the time for the decisive battle between the offensive and defensive sides, and there is no way to retreat, the attack will be fierce, and the code will be firm. Everyone was still in the aftertaste, and when they heard that the master was going to talk about the most wonderful things, everyone rose up at a moment, and their eyes were blazing to look at the case.

"There are three ways to go down to the city, to climb the wall, to attack the gate, and to dig a tunnel. Before attacking the city, they should first use trebuchets to throw boulders and fire oil into the city to disrupt the enemy's defense and kill and injure the defenders. Then use the ladder and siege tower to lead the troops up. The siege tower consists of two parts: the tower body and the inclined ladder. The body of the tower is made of rhino bark by Nanmu roasting fire and then wrapped, about five zhang high and about one zhang wide, divided into three layers, carried by four axles and eight wheels, and manpower is pushed behind. Once the tower is close to the city wall, the besieging soldiers go up to the top floor from the inclined staircase behind the tower, lower the bridge, and enter the city wall through the bridge. The lower middle layer is used for cover. It is hollow inside, can store more than 10 soldiers, there is a gap, when the soldiers of the top layer attack the city, the defenders will block, and the soldiers of the middle layer of the siege tower attack with it in the gap, in order to cover the soldiers to climb the wall. The lower layer has built-in weights to protect the tower from falling. The overall structure is shown in this figure. After speaking, he took a scroll from the desk and threw it to Xia Chenghuan.

Everyone left their seats in an uproar and gathered towards Xia Chenghuan. Xia Chenghuan carefully opened the scroll, only to see that there was a complicated and mighty thing in the scroll, there were hundreds of words on the left and right sides for explanation, and there was a stamp of the Ministry of Engineering at the bottom right. In the middle of the scroll, there are five characters in the big book: Duan's siege tower.

Everyone looked at the illustration carefully, compared the illustrations, and gradually realized how extraordinary this was, and a behemoth slowly took shape in their minds. After reading it, Huangfu Tianzong said, "With this artifact, why worry about the city?"
