What do you mean by swearing? Hong Lianshuo listened to the black lines on her face, did she look unreasonable? It's just that he has a louder voice and resolutely refuses to admit that he has a bad temper.

"It doesn't have to be me to find the mistake in time and correct it! Your comrades eat, live and train together, and they don't know what's wrong with them! It is only right to bring it up in time and help my colleagues correct it." Hong Lianshuo looked at them more softly and said.

"I'll remember!" Li Shuangzhu nodded heavily.

"I'll say one more thing! It's about finding mistakes, not picking bones in eggs, deliberately picking thorns." Hong Lianshuo looked at them seriously and said, "You have to master this degree! It's too much."

"I know that we are acting from the public and from the interests of our team as a whole." Li Shuangzhu looked at them firmly and said.

"That's right." Hong Lianshuo looked at him with satisfaction and said.

Hong Lianshuo looked at them with clear eyes and said, "I think the siege is simple, so I asked the Venerable Master to gather and see how the offensive and defensive battles were fought."

"Yes!" Li Shuangzhu replied loudly.

"Meet at the school grounds." Hong Lianshuo pointed to the direction of the martial arts field.

"How's that going to be?" Han Baohu looked at her with some concern and said, "Do you need to draw? Simple diagrams, more convenient and intuitive to say."

"There are models, intuitively let them feel the siege and defense of the city, and see how easy it is." Hong Lianshuo looked at them with deep and upright eyes and said.

"So let's go, what are you waiting for?" Lin Nanzheng looked at them eagerly and said.

"Let's go to Cao Lao first and move the model to the school grounds." Hong Lianshuo looked at them with clear eyes and said.

"You go to the school, I'll go to Cao Lao." Lin Nanzheng volunteered.

"Then let's go!" Han Baohu looked at Hong Lianshuo and said casually, "I don't know if Old Cao has gone back?" They're going to see drills, too."

"We should go back now!" Hong Lianshuo said as he walked.

The two walked to the school grounds, and after a short time, the soldiers carried small horses and lined up in a neat line, walked over, and stood in their places.

"Sit down." Hong Lianshuo's clear eyes looked at them with his hands pressed down, and he looked at them with a smile on his eyebrows and said, "I know you have questions in your hearts, what are you doing here after this exercise?" I'll tell you about the defense of the city!"

After that, Lin Nanzheng and Cao Huaimin hugged the model over.

Under Cao Huaimin's guidance, they put the model on the straw mat.

Intuitively facing the model, especially oversized, as big as the bed they slept on, or more specifically half a house.

The soldiers were stunned, "This ...... Isn't this our eastern gate?"

"That's right, it's the East Gate of the drill just now." Hong Lianshuo took a long bamboo pole with thick fingers and pointed to the city wall and said.

"Now I'm going to talk about the battle against the walls." The "Whip" in Hong Lianshuo's hand began to speak, "After the attacker starts to attack the city, the attacker must stand against the ...... from the front of the sheep and horse wall" and nodded, "This is the sheep and horse wall!"

"We don't have a sheep and horse wall, it's just a city wall." Lin Nanzheng raised his eyes and looked at her and said.

"Therefore, when building the horse face, it is also a sheep and horse wall fortification." Hong Lianshuo pointed to two special places.

The sheep and horse wall is the inner moat wall of the moat outside the city tower, and it is a fortification similar to the city circle built by the enemy outside the city, especially after the moat freezes in the north winter, the sheep and horse city located outside the city wall bears the brunt and becomes the first fortification.

"The wall of sheep and horses is five feet high, and it reaches to the shoulders of men." Hong Lianshuo nodded his shoulder with his thumb and said, "However, the base is five feet thick, which means that the besieging side must get off the mount and climb over it in person to pass."

Cao Huaimin smiled and said, "In siege warfare, even if this layer of sheep and horse wall is not very high, it is also an insurmountable obstacle for the attacker - to climb over this sheep and horse wall, they will inevitably be counterattacked by the defenders, and even if they successfully jump into sheep and horse city, the narrow terrain makes it impossible for them to deploy siege equipment such as ladders."

"Ambushes were set up within the walls of sheep and horses, and spears were used to attack the enemy who crossed the moat. If the enemy breaches the sheep and horse wall and only opens a small opening, the defender can use the sheep and horse wall and the wall to entertain the enemy who is crowded and enters through the narrow opening, so that they will be attacked on the one hand and attacked on the other. Even if the sheep and horse wall is breached, because the space between the sheep and horse wall and the city wall is reduced, the army cannot be fully deployed, and it is difficult to use large siege equipment." Hong Lianshuo's bright eyes sparkled as he looked at them and said, "The most important thing is that this kind of sheep and horse wall doesn't cost much money and is easy to build, but it can have a miraculous effect of stopping the enemy's soldiers! It's really cheap and sufficient, in short, affordable!"

"And what is the bulge outside the wall? I didn't see it when I built the wall." Lin Nanzheng pointed to the horse-faced wall.

"The purpose of this horse face fortification is like this...... Hong Lianshuo gave a detailed introduction to what the horse face is and what role it plays in the fortification system.

"Defending a city is not as simple as a city wall." Hong Lianshuo's clear eyes looked at them and said, "The entire city wall defense system, several major areas of the atmosphere, moats, suspension bridges, sheep and horse walls, urn cities, city towers, and arrow towers are several major parts." The whip in his hand was one by one.

"The first line of defense of the city is the moat, and beyond the moat is the sheep and horse wall." Hong Lianshuo looked at them with deep and upright eyes and said.

"Why is it called the Sheep and Horse Wall?" Han Baohu looked at her puzzled and asked.

"The sheep and horse wall, as the name suggests, is mainly used to protect the livestock of the people who have taken refuge in the countryside in the city." Hong Lianshuo raised his eyes slightly to look at them and said, "When the Hu soldiers besieged the city, the people outside the city drove cattle, sheep, chickens and ducks into the inner city."

"yes, it smells terrible, and it's noisy." Lin Nanzheng pursed his lips and said with disgust.

"The plague in the city is because of them, and men and animals are gathered together." Hong Lianshuo reminded them.

As soon as these words came out, everyone's faces changed greatly, although they were healed and did not leave terrible sequelae, but the tragic appearance of purgatory in the city could not be forgotten in this life.

"To get back to the point, this wall of sheep and horses was built for the cattle outside the city." Hong Lianshuo snorted coldly and said, "Not a single chicken feather will be left for the enemy."

"That's it! We've worked so hard to raise it." Chen Zhongyuan shouted in a loud voice.

Hong Lianshuo smiled when he heard this, "The horse raising wall also plays the role of a fortification outside the city, it is the inner moat wall built into the outer moat, and it is also the second line of defense after the moat. When the moat is broken or freezes in winter, the sheep and horse wall can be an effective way to hold back the enemy. This is what Elder Cao said just now, so I won't repeat it."
