Three Kingdoms: I'm really not a fierce general!

“What way?” As soon as he heard this, Cao Cao immediately became interested, and an expectant look appeared on his face.

“Yixuan, hahaha, you are really my lucky star!”

No matter what method it is, first praise a wave and then say, anyway, Xu Zhen will not disappoint.

Cao Ren said with some concern: “However, if we ask for it now, I am afraid that Liu Bei will immediately know that we have the intention to retreat, and this person is not an ordinary person.” ”

When the Eighteenth Route Alliance Army, Cao Cao personally brought Liu Bei into the land of the alliance army, otherwise he would not have been able to enter, and there would have been no Three Ying Battle Lü Bu.

So at that time, Cao Cao had begun to let Cao Ren and Liu Bei contact the three brothers, and he originally planned to take them under his command, but found that Liu Bei was not a person who could subordinate people.

Cao Ren also praised his two righteous brothers as masters of the world and heroic spirit.

“Of course, but let him take the initiative to seek peace, and it will be easy to do.”

Xu Zhen said with a smile.

Cao Cao and Cao Ren looked at each other, and they didn’t know what kind of medicine was sold in Xu Zhen Gourd.

“What’s that way? Oh, Yixuan, say it quickly! Cao Ren scratched his ears and cheeks in a hurry, he was not as calm as Cao Cao, so he wanted to know urgently.

Cao Cao’s mentality was very stable, because he knew how to let Liu Bei retreat by himself, which was a deterrent.

If he can show the ability to break through Xia Pi at all costs, I’m afraid Liu Bei will also be afraid, after all, he doesn’t want to see Xia Pi being breached… He also plans to get a place to live.

But now if he wants to capture Xiaping, Cao Cao will also pay the price, so he is also very much looking forward to what kind of hole card Xu Zhen can play.

……

A few days later, when Yuan Cao was holding each other in Guandu, Yuan Shao’s army would use a large siege equipment to raise the tower, which made Cao Cao suffer a lot, and even the camp was not safe to be fired by ten thousand arrows.

Then there was Liu Ye who offered a plan to break the high bridge with a catapult.

In fact, it is not mentioned that Liu Ye invented it.

Later, it was improved by Ma Jun and further improved.

But it doesn’t matter if you mention it or not, now it’s all Xu Zhen’s things.

……

After a few days, after a little quiet in the camp, Xu Zhen found a pair of craftsmen, and many fierce warriors led by Dian Wei went up the mountain to cut trees day and night.

The accompanying carpenter 23 teachers, blacksmiths and 50 skilled blacksmiths, under the command of Xu Zhen, made a new catapult, and according to a certain principle called “parabola”, angles and distances were also measured.

This craft… Soon word spread throughout the army.

When it reached Cao Cao’s ears, it was simply shocking.

“Catapult? He also improved the catapult … My God…”

Cao Cao leaned on the backrest, with a hint of incredible confusion on his face, he felt that all this was very unreal, as if it should not happen in front of his eyes.

Can Xu Zhen also improve the catapult?

“Go! Let’s see what it can be improved into!? ”

Cao Cao put on a robe in the middle of the night, stepped on his shoes casually, and walked out of the camp, and soon saw that the soldiers were all gathered in the middle of the camp, and a large catapult came into view.

The first is a huge base, with a counterweight basket at the front, and a throwing bar that is more than ten meters long and nearly twenty meters long.

Hanging the throwing rod with a counterweight, placing it on a boulder, tying a rope, and then adjusting the angle using gears, it can be launched hundreds of meters away.

Xu Zhen stood in front of this catapult that was more than ten meters high and repeatedly checked, almost all of them were checked, and nodded frequently.

“Well, almost, a counterweight catapult that uses the principle of leverage.”

Dian Wei clapped his hands, the knotted muscles on his body stirred a few times, scratched his head and asked: “Sir, this thing is too heavy, even if there is this wooden wheel, it will take more than twenty people to push it.” ”

Such a big fellow, if the power is not good, it will be embarrassing.

“My lord, what’s your name? Is it a catapult? ”

“Is this an improvement from Spring and Autumn?”

“Master Xu Zhen, how do you understand everything? And so brave! Be our general! ”

“Yes! If you lead, you will definitely be invincible! ”

Xu Zhen waved his hand, “No, no, the leader this… It really hurts the body. ”

Then turned to Dian Wei and said: “This can’t be helped, the engineering weapon of mass destruction is like this, fortunately, this is a unique product, there is no way to mass produce it for the time being, and the workmanship is relatively rough, I don’t know how many times it can be used.” ”

As soon as the words fell, Xu Zhen heard Cao Cao’s voice.

“Yixuan! Oh, Yixuan, this is the surprise you gave me? ”

Cao Cao raised his head to look at this big fellow, he hadn’t come out and moved much recently, he was all in the front camp of the Chinese army, and he didn’t notice that there was such a big movement here when the rear camp was approaching the Chenzhong camp.

“This is a catapult?”

Xu Zhen nodded and said: “This should be called back the back artillery, in short, it is a very powerful offensive and defensive equipment, and it is effective in defending and attacking the city.” ”

“Dian Wei, try it at night!”

“Okay! Leave it to me, my lord! Dian Weimo was quite excited.

This time the cannon is actually a huge stone thrower, hitting an oversized boulder.

After listening to this principle, Cao Cao excitedly held Xu Zhen’s hand and marveled, “According to legend, in ancient times, the Yellow Emperor and Qianyou fought each other, and they were invincible, so the heavens sent the Nine Heavenly Xuannu to come to help!” ”

“Yixuan, you are my Nine Days-”

“Stop, stop, stop…” Xu Zhen hurriedly raised his hand, and it was wrong to continue talking.

Looking closely at this trebuchet, how big is the stone that can be launched?

According to this scale level, the history books record that it is 150 pounds, if it can also be achieved, just imagine a 150 pound boulder thrown to a height of more than ten or twenty meters, and then falling, the potential energy obtained is enough for the enemy to drink a pot.

Xu Zhen remembered that there were records in the Yuan history that this stone could sink seven feet when it landed, which shows its great power.
