Looking at the battle between the offensive and defensive sides in front of him, Li Er discovered something, that is, Yang Heng's training for these soldiers was to focus on attacking rather than defense.

Why? This is because both sides have the same weapons, but the attacking side has a greater advantage. How can we see this? It can be clearly seen that the siege's shields are slightly fewer, with more bows and arrows, while the defending side is different. They are basically considered equal bows and shields. However, this may be because the position above the city wall gate limits the deployment of the defending side.

However, Li Er guessed one of them correctly and Yang Heng's view of war. In his opinion, war should be better off offensive. He does not like the defensive. The so-called defensive is like being passively beaten. Although the city wall will have a certain impact on the defender, it is not unsolvable. However, Yang Heng just doesn't like the defensive. This can be seen from his previous training. His goal is to move forward, advance and then move forward. Even the scouts in this barracks will arrange for patrol every day, and sometimes he will arrange people to conduct anti-reconnaissance training on the scouts. In this way, this team here is equivalent to giving strict defense to the entire north of Chang'an City. At least within fifty miles, if the enemy appears, the enemy's traces will be quickly discovered.

When Li Er was thinking about it, the attack and defense in front did not stop moving, the defenders above the city gate were still shooting, while the attacking party below was shouting slogans behind the shield and following the shield. This is the advantage of the attacking party. This can start with ballistics. Shooting down from a high place, with his advantage, and naturally his weakness. That is to say, from the top to the bottom, the angle of the arrow is fixed, so as long as the shield is placed, it is easy to block the arrow in front. If the force of the arrow is very strong, the archer behind can push the shield player behind the shield player, so that it can easily resist the attack in front.

The arrow designed by Yang Heng is a strong arrow. Although the arrow is twisted off, the place where the arrow is installed is also made of iron. Although this arrow will not shoot injure people, it can hit people. If it is a coincidence, it will also cause fractures. This is the attack arrow specially designed by Yang Heng, which is also a training arrow. If there is no arrow during training, the accuracy of ordinary arrows will be greatly reduced. This kind of arrow is the same as actual combat, which means that it has some guarantees for life, but does not guarantee the safety of both sides of the training. Therefore, a training game is not much different from a practical battle. Even if it is occasionally shot by chance, someone will die.

"General Yang, what kind of arrow is that? Take one to show me." Not long after, Li Er also saw that the difference between arrows was coming, because he found that the soldiers who were hit were grinning, which seemed to be very painful. So he became curious about the arrows.

"Your Majesty, this is a practical training arrow designed by Xuewen. During training, this kind of arrow can be recycled and used. Even on the battlefield, it can also be recycled and used, but the enemy cannot use it." The father arranged for someone to send an arrow to Li Er and explained to him.

"This is not, this is the arrow that you train for. Will it take no life to shoot on a person?" Li Er got a complete arrow. "Your Majesty. There is also a mechanism here. During training, this arrow can be twisted off," Dad demonstrated to Li Er.

"Well, it's good, a good idea. No wonder you spent so much, and they all used it."

"Reply to Your Majesty, this academic article says that the cost of arrows is not much, the cost is on the bow. If there is no good bow, this kind of arrow will not be shot."

"Oh, what kind of good bow is, take a look." What good bow is this kind of bow, which is a unique design of Yang Heng. In this era, if you make a good bow, it will be difficult to make a bow in less than a few years. Of course, good bows are used by some generals, and the lifespan of a good bow is limited, so there is the saying that the treasure of the family is not used too much. It is just that it is representative and a symbol of identity.

But the bow designed by Yang Heng is a kind of bow used by the public. He is a bow body made of hardwood and steel plate, a bow string made of animal tendons, and even animal skin. What is particularly rare is that the bow body is a separable component. Once it is damaged in a certain place, you can find accessories and modify it. This is the focus of this bow, which means that this bow is a product for assembly line operation. Although it is valuable, it is not expensive.

"What is this? A bunch of strange things." The father was also a little striking, and he didn't bring Li Er a finished bow, but instead brought the pieces.

"Your Majesty, this is a bow. Look, just like that, isn't a bow done?" Twist the left and right, and soon a bow was assembled in the father's hand.

"Well, it's good, it's good. Let me try this weird bow." Li Er did not look at the strength of the bow, but wanted to pull it away casually, "Oh, this actually requires a lot of strength. These are two stone bows." The first one was not strong enough, and Li Er could not hold on to the face, so he naturally told the strength of the bow, so he didn't make people laugh, and then pulled the bow away with force.

"Not bad, right, by the way, can these archers pull away?" "Your Majesty, you can pull away, you have been trained. They can pull away five times at a time, so there is a segmented attack and a segmented defense method to practice."

My father's words solved Li Er another confusion, and he was also wondering why both parties in the drill had to practice like this? So that's it.

"Team A, team B, evacuated." When Li Er was about to ask again, he suddenly heard the order for both sides to evacuate during the drill.

"Your Majesty, let me demonstrate the explosion of the city gate now. The attacking team in front has already attacked the city gate. In order to prevent losses, I asked all the soldiers near the city gate to evacuate. Your Majesty, see if you bomb now." "Then bomb, let me see how you bombed a solid city gate." "Yes, Your Majesty, but I have a small request, that is, when I raise my hands, I should ask Your Majesty to open your mouth, preferably cover your ears with both hands, otherwise the sound will be too loud, and so will you." Yang Heng said to the people around Li Er in the following sentence.

"Is it really going to be like this? Is there such a loud voice?" "Yes, Your Majesty, and I have also issued such an order to all the soldiers below." "Then, okay, I will listen to you."

"Preparation." Yang Heng shouted, and the guards behind him ran out with a few packages. When they arrived under the city gate, they began to dig holes beside the city gate.

"Your Majesty, I have to use my guards for this. The soldiers here have not yet undergone this kind of training, so they can't let them do this job." Yang Heng also explained to Li Er why he used his guards to do this.

"Prepare," the guards in the distance dug the pit and put the things into the pit. Then one of the guards raised his hands and shouted loudly, while the other guards ran back quickly.

"Impot the fire." Yang Heng also raised his hand and waved it down hard. The guard took out a fire break from his waist, then ignited several leads, and then quickly ran to a pit dug in advance. Because the fuse burned for a short time, he dug a hidden pit nearby. This is why the guards in front ran away quickly. If they were ignited, they would not explode.

"Boom," as the guard jumped into the pit, a loud bang rang out, and then there was a smog of smoke in front of him, and the city gate exploded with the fall of the walls on both sides.

How much gunpowder has been put on? Yang Heng thought resentfully that this was really done. He just asked the Taoist priests to put more gunpowder, but he didn't let them put so much.
