"Knock, knock, knock......" The multi-faceted war drums beat one after another, slowly and rhythmically, and the sound resounded through the sky, even the defenders on the city wall could be clearly heard. Every time the war drum sounded, the footsteps of the soldiers of the Yuan army took a step, and the movements were neat and consistent.

The other three Yuan armies also beat the war drums at this time, and for a time the sound of war drums spread to every corner of the plain city.

The sound of war drums became more and more urgent, and the pace of Yuan's soldiers became faster and faster. The distance between the two sides is getting closer and closer, and the sword and shield soldiers and ladders at the front have entered the range of the defenders' bows and arrows, and the defenders have drawn their bows and arrows to stand by, as long as they give an order, they can release their arrows at any time.

Yuan Jun's catapult began to might, and more than 30 boulders roared! Some of the defenders with bows and arrows hurriedly hid behind the women's wall, and the big stones arrived in the blink of an eye, some smashed on the wall, some smashed on the wall, and some flew over the city wall and smashed into the houses in the city, and there were not many casualties, but many people were frightened and turned pale.

The sound of the war drums of "Dong Dong Dong ......" has lost its original rhythm so fast that it has lost its original rhythm, and the 100,000 horses of the Yuan army have rushed towards the city wall with shouts, and the scene is very spectacular!

The county town more or less has crossbows**, and when the Yuan army is about one hundred and fifty meters away from the city wall, sixty crossbows ** on the city wall begin to might! Sixty bows and arrows comparable to spears flew towards the Yuan army, and after a short flight, they plunged into the Yuan army's array, some of them could not shoot anyone to the ground, and some shot through the body or limbs of the Yuan army's soldiers, nailing them to the ground together!

Only nearly 100 people died, and for the 100,000-strong Yuan army, it was nothing.

With the tidal charge of Yuan's army, it was only a hundred meters away from the city wall, which was the best range for bows and arrows. For a while, there were thousands of arrows on the city wall, and the first wave of arrows under the black pressure flew towards the soldiers of the Yuan army! Before the rain of arrows landed, the defenders of the city took out new bows and arrows from the quiver and continued to release arrows at Yuan's army.

Yuan's saber and shield soldiers blocked the shield at a slanted angle of forty-five degrees, resisting most of the bows and arrows. A few of the less fortunate soldiers were shot in the leg or side with bows and arrows, and fell to the ground screaming. If he hadn't died, he would have been shot with a bow and arrow not long after.

The catapult was once again powerful, and more than thirty boulder meteor showers flew towards the city wall! More than a dozen defenders were smashed to pieces like watermelons that had been thrown to the ground because they didn't pay attention when they took their bows and arrows, and they were miserable! One of the crossbows** was also hit by a boulder, and the crossbow** and the defending soldiers who were operating were flattened together!

After a long time of hard work, the crossbow ** was finally loaded, and fifty-nine giant arrows pierced into the Yuan army's array, a few could not shoot anyone, and all the shots were nailed to the ground, even the shield of the sword and shield soldiers was shot through!

Yuan's army rushed to the moat under the city wall like a tide, the ladder leaned against the city wall, and the soldiers climbed up one after another like ants in an ant's nest. Many soldiers of the Yuan army carried their own hooks and ropes, and they took out the iron hooks and shook them a few times, so as to increase their inertia, and then threw them hard at the high wall! Some hooked the women's wall and began to climb, while others hooked the defenders, ripped them off and started all over again.

The archers of the Yuan army were already in position, and they did not need to wait for orders, and fired arrows directly at the defenders on the city wall, providing fire support to the friendly forces as much as possible. However, the effect is not very good, or the shot is too low and blocked by the wall or battle grid; Or shoot too high and don't know where to fly.

When the enemy began to climb the walls, the defenders reacted immediately, either lifting rocks or lifting huge logs and throwing them down, or pouring boiling grease down the walls!

Each stone weighs about 100 catties, and the weight is full, and it is not too much to say that it is injured when it is touched and killed when it is next to it. The giant wood is a solid wood with a diameter of more than 30 centimeters, weighing about 200 catties, no matter how many sergeants (usually six or seven people) are climbing on the ladder, the giant wood rolls down the ladder, and the whole ladder is clean. And the grease up to nearly 200 degrees Celsius is the most disgusting, and those who are splashed all scream and fall down, rolling all over the ground, life is worse than death!

Yuan Jun's two twenty-meter-high Xuan chariots Shanshan arrived late and slowly approached the city wall of the plain. The two chariots resembled four-wheeled vehicles supporting a high platform with a rudimentary fence, protected by the shields of sword and shield men in front and on both sides, and archers in the middle.

The archers on the chariot condescendingly fired arrows at the defenders on the city wall, and for a time the defenders were shot and killed. Xie Chengbin saw that the situation was not good, and ordered the crossbow ** to be aimed at the Xuan car, and it happened that the crossbow ** had already completed loading at this time.

......More than 50 powerful bows and arrows flew towards the Xuanche platform one after another, almost half of them missed and did not know where to fly, and the other half hit the target and shot many Yuan soldiers.

At this time, several places on both sides of the city wall were killed by the Yuan army, Xie Chengbin and Guan Hai each led their cronies to rescue everywhere, and it took a lot of effort to kill the Yuan army.

This side is temporarily safe, and Yuan Jun is killing not far away, Xie Chengbin began to be busy running around, and even sometimes there are waves of unsettled. Killed batch after batch, as if I couldn't finish killing it.

At this moment, a herald rode a horse and ran towards Xie Chengbin. It happened that Xie Chengbin killed Yuan Jun who came up, and the blood had already dyed Xie Chengbin into a bloody man. "Lord Qi, under the command of General Yu, Chun Yuqiong led his troops to rebel, and the north gate is crumbling and in danger!"

"What!" Xie Chengbin, who was a little tired, was taken aback when he heard this, wondering if he had heard it wrong. This Chun Yuqiong Xie Chengbin knew that he was incorporated when he defeated Yuan Jun a few days ago, and he thought that the people who stayed willingly would be fine, but he didn't expect that there would be a rebellion! It seems that this person deliberately stayed as an undercover agent! Xie Chengbin didn't have time to think about it, put it down, took out a token from his arms, and handed it to the herald. "Immediately go to the school to pass on my military order, and let General Zhang lead the iron cavalry to the north gate to quell the chaos!"

"Whoa!" The herald took the token after holding his fist at Xie Chengbin, turned over his horse very neatly, and rode away with a U-turn.

Xie Chengbin asked another crony to go to the county government to call Guo Jia over, and at the same time silently prayed that the north gate was fine, and if he couldn't hold it, he would escape with Guo Jia.

The sound of war drums and shouts resounded through the sky, the entire sky was covered in dust and black smoke, and the once bright sunlight now looked red. What used to be a clear sky is now a miasma, a little dim, and visibility is greatly reduced.

The Yuan army attacked from the morning until the evening before Mingjin withdrew his troops, and although the Yuan army attacked the city wall many times during this period, it still failed to take the plain city.

Chun Yuqiong led a hundred cronies to rebel, and was defeated by the iron cavalry when he tried to open the north gate. Zhang Fei cut off Chun Yuqiong's nose in a fit of anger, and the rest of the dozen or so pawns were all cut off. Xie Chengbin felt that Chun Yuqiong was very backbone, and he didn't want to kill him, but Guo Jia said that Chun Yuqiong would think of today when he looked in the mirror in the future, so Xie Chengbin beheaded him.

Yuan's army suffered nearly 40,000 casualties (not counting minor injuries), and the loss was only one-tenth, which can be said to be painless. The defenders suffered more than 10,000 casualties and lost a third of their troops, which was considered a heavy hemorrhage.

In the plain school field, more than 5,000 injured soldiers were in pain. Looking at the wounded soldiers everywhere, Xie Chengbin's scalp was numb, even if Xie Chengbin's blood was dry, it was not enough to save so many people, thinking that it was too impractical to build a biochemical army by infection alone, and that scientific and technological means should be used to improve the combat effectiveness of the army.

Today, Xie Chengbin saw the crossbow ** for the first time, and felt that the crossbow ** was very powerful, but the accuracy was too low and the loading was too laborious (very slow), if there was any way to improve, then it would definitely be a necessary weapon for home travel, killing people and goods! But after thinking about it, I couldn't think of any good way after spending a lot of brain cells, so I could only quietly ask Cody for help. "Cody, I want to improve the combat effectiveness of the army, is there a way for you to make those crossbows easier to reload? Or do you connect instead? ”

"O great lord! Aren't you embarrassed? The reason why this crossbow is powerful and slow to reload is because it uses multiple bows in combination. If you want to reload faster, then you can reduce a few bows directly in the crossbow**, but in that case, the power of the crossbow ** is greatly reduced, and it is not as good as using a bow and arrow alone. It must be powerful and connected, at least there must be an engine, otherwise it will be difficult for a clever woman to cook without rice. Cody's grumbling voice sounded like he had been wronged.

"That's it......" Xie Chengbin was a little helpless, even Cody was helpless, it seemed that there was really no way. Is there any other way to improve the combat effectiveness of the army? ”

"It's not difficult, just improve the army's equipment. If every soldier were equipped with armor and helmets like your generals, wouldn't it be possible to run amok. In this era, the technology of refining iron ore is not backward, but the technology of iron ore exploration is relatively limited, for example, there are very rich minerals in Licheng, and no one knows about it. Cody's tone was extremely understated, and it seemed to be light-hearted.

"Ahh You didn't sue me sooner for such an important matter?! Xie Chengbin was angry, and he couldn't wait to find a hammer to smash Cody to pieces! If I had known earlier, how could my own army have died so many people?!

"Uh...... You didn't ask sooner. Seeing that Xie Chengbin was about to run away, Cody realized that the joke was too big and he was a little lacking in confidence.

"......" Xie Chengbin was speechless, he was completely defeated by Cody, a non-human is a non-human, it is really different, there is nothing to say.
