Most of the ancient city walls were built with rammed earth and brick walls outside. Although rammed earth is earth, it is strong and ruthless. The walls of many small cities do not even have green bricks, and they are simply made of rammed earth.

The most famous is Helian Bobo's Tong Wancheng, who is said to have ordered soldiers to wedge the wall with iron nails, and kill the builders of the city by an inch of the wall, and kill the soldiers if they did not enter the wedge. Fifteen hundred years have passed, and the city is still there.

In addition to being used to build city walls, rammed earth was also used to build tombs, and many princes' tombs were also made of rammed earth. Anyone who has read a tomb robbery novel knows how laborious it is to dig rammed earth. It shows that rammed earth is strong and is a building material that has been proven to have practical value in practice.

The section of the city wall where the Fuzhou Gate is located was originally built along the lake, and there was nothing bad about it, and the enemy army could not take a flying ladder in the lake to attack the city. But I ran into Chen Youliang's strange thing, and directly used a giant boat to approach the city, the city wall is almost as high as the deck, and it is convenient to attack the city.

A few years ago, Chen Youliang led a giant boat eastward, and it was in this way that he captured Taiping, Anqing and other places, but unfortunately Longwan was defeated and the captured territory could not be saved.

As soon as Zhu Wenzheng arrived in Hongdu, he guarded against Chen Youliang's hand, and without saying a word, he demolished and rebuilt the city wall, gave way to a large area of vacant land, and rebuilt the city wall, and the area of Hongdu was also reduced by a full fifth.

Although there is no need to pursue the ultimate of perversion in Tongwancheng, it can't be such a tofu scum.

On the outside of the city wall, the green bricks have collapsed in large areas, and the soldiers who defended on the city wall fell to the city as the collapsed city wall fell, and the city wall was also screaming again and again, and it was estimated that many Han soldiers were buried.

Ma Du made a visual inspection, and collapsed about ten zhang long, and the originally not wide city wall lost nearly half of the area, and the loess mixed with masonry was still peeling off automatically, and the dust was flying.

Stunned, all the people on the city wall were stunned, and no one thought that the city wall on which they were leaning would collapse. Madu felt that at this time the defenders definitely had the urge to run away, because he himself had it.

How could a good city wall collapse, it was his own butterfly wings that fluttered and collapsed? Or is it going to collapse? Ma Du kept searching for historical knowledge about the defense of Hongdu in his head,

Zhu Wenzheng, Chen Youliang, 20,000 against 600,000, lasted 85 days...... It seemed like that was all there for, and for the first time he complained that the chattering high school history teacher didn't teach the lesson in more detail, or that he shouldn't have slept with his head covered when he was in history.

It's over, it's over, he really can't think of how 20,000 soldiers can face Chen Youliang's 600,000 people without the protection of the city wall, even if it is ten for one, the defenders of Hongdu City can be exhausted.

After a moment of silence under the city, there was a violent cheer, and then some soldiers attacked the city along the slope formed by the collapsed masonry, but the slope was still very steep, and there was still some distance from the city wall above.

There were also many Han soldiers with short pickaxes and shovels, throwing at the earthen wall for a while, and a big pit could be dug out with a pickaxe, and the earth rolled out of the city, and the earthen wall inside was lowered in the blink of an eye.

What kind of rammed earth, it's fucking mud at all, and the adobe houses in the people's homes are stronger than this.

Zhu Wenzheng's eyes were cracked, his fists were clenched, and he roared angrily: "What are you doing in a daze, don't you hurry up and get on the Rolling Wood Thunder Stone!" Let Liu Qianhu lead 200 people to guard the city horse road, and the rest of the soldiers will guard the city wall at any time to meet the attack, let the other gate guards divide into forty percent of the troops, organize all the auxiliaries to prepare to build the city wall, and let the treasurer send all the thunderbolts over......"

Zhu Wenzheng gave orders in an orderly manner, with a rare calmness. After he finished speaking, Deng Yu took a step forward, "I'm afraid this small section of the city wall can't be saved, so let me guard it." ”

Zhu Wenzheng looked at Deng Yu's arm, "But Boyan, you ......, you should guard it, others don't have this ability, the soldiers under the city and the soldiers who come to help are controlled by you, and you must guard them and not let them break through the city wall." ”

"Whoa!" Deng Yu answered, and hurried down to the city.

Ma Du hurriedly followed, "Deng Shenzheng, you can't cure your injury, otherwise you will bleed to death before the battle is over." ”

"Thank you, sir, it's just that Deng has a duty and can't be a deserter anymore, even if he dies, he can't live up to the expectations of the national government anymore." Deng Yu arched his hand as he spoke, and went down the city from the road to the city.

In the end, he is the sixth best general in the world, and he is still very courageous. But Ma Du really wanted to tell him that there was really no need to work so hard for Lao Zhu, even if you didn't live up to him, he would let you down.

The attack on the city wall was much weaker, only the collapsed city wall was shocking, and the rolling wood and simple grenades were thrown over as if they were not for money, bringing up fluffy blood and terrible screams, but they still could not prevent the continued collapse of the city wall, and the simple grenades seemed to play an auxiliary role.

The area of collapse is getting bigger and bigger, there are more and more arrows, shooting at both sides of the gap, to cover the Han army in action, the ram keeps hitting the last wall, and the muffled sound vibrates on the city wall, making people's hearts jump out.

"Deng Shenzheng, wait a minute!" Ma Du chased down the city wall, and Zhu Wenying also followed with a shield.

Deng Yu was already organizing a defensive formation, and it seemed that he was preparing to make his firearms battalion the main force, and he didn't know what this kind of firearm with a slow rate of fire and low power would look like against a pure cold weapon, and whether he would have time to load ammunition.

"Marshal Deng......" As soon as he walked in front of Deng Yu, an arrow shot from the city wall towards them, and Ma Du was so frightened that he shrank down with his head in his hands.

Deng Yu didn't move, stretched out his hand and pulled it up, "The arrows from the city wall at this position can't hit people." “

Zhu Wenying chased after him, "What are you running around, and you don't wear armor, one arrow can kill you." As he spoke, he stood in front of them with his shield in hand.

Ma Du smiled awkwardly, "Deng participates in politics, you choose a position suitable for your command, and I will operate on you here." Deng Yuquan relied on the tight bandage on his upper arm to stop the bleeding, not to mention that the effect was not good, if it came down for a few hours and there was no blood flowing, this arm would have to be amputated.

can't let his little wings fan Deng Yu to death in advance, he has to let him live to see Lao Zhu's real color. Of course, what Ma Du is most worried about is that if such an important person as Deng Yu dies, Hong Du will not be attacked, and whether his life can be saved.

"Okay." Deng Yu was not hypocritical, "This location is very good, let's do it here." I'm tired of Mr. Tired! Then he stretched out his hand and summoned two men with shields, and guarded them on Mado's right and left.

Ma Du hurriedly took out his tools from his purse, and as soon as the tweezers held the alcohol cotton ball and touched Deng Yu's wound, he heard a loud bang! I saw a large hole less than two meters high from the base of the city wall, and a large amount of masonry burst out, and what was exposed outside the hole was a huge metal-wrapped ramshell!
