Three Kingdoms: At the beginning, I revealed to Liu Bei that I was a time traveler

Everyone gathered around, looking at the picture with blank eyes.

"Strategist, what are you drawing on here?"

Zhang Fei touched his skull, and his eyes widened.

Xiao Yuan looked at Zhuge Liang: "Liangzi, can you tell what it is?"

Zhuge Liang in history is also a master of weapons, and he has studied weapon manufacturing since he was a child.

"Teacher, what is painted on this... Like a trebuchet?".

After staring at it for a long time, Zhuge Liang saw some clues.

"Trebuchet?".

"I've never seen a trebuchet, how could this thing be a trebuchet, you guess. "

Zhang Fei was full of sarcasm.

Zhuge Liang was slightly embarrassed.

"This thing is called the Xiangyang Cannon, and it is indeed a trebuchet, but it is a new type of improved trebuchet. "

Xiao Yuan didn't hang everyone's appetite, and told him directly.

As a Ph.D., the history of ancient science and technology is one of the compulsory courses.

The structural diagram of this Xiangyang cannon is actually just a copy he copied from a textbook.

"Huh?".

"Is this a trebuchet?"

Zhang Fei was dumbfounded.

Liu Beiqi said: "Changsu Military Division, why is this trebuchet on the picture so weird, and why is it called Xiangyang Cannon?"

"Do you remember the Mengyuan Empire I mentioned to my lord?"

Xiao Yuan asked rhetorically.

Liu Bei was stunned for a moment, and then said: "I naturally remember that the military advisor said that this Mengyuan Empire spans Europe... What is the Eurasian continent, the vast territory of the country, ancient and modern, there is no dynasty that can match!".

"The lord is right, it's this Mengyuan Empire. "

"Although the Mengyuan Empire swept through Europe and Asia, it could not destroy the Song Dynasty in the south of the Yangtze River, especially Xiangyang City, which could not be captured after more than ten years of siege. "

It was not until later that the Mengyuan Empire used counterweight technology to create this new type of trebuchet, which collapsed the city wall of Xiangyang. "

"So this trebuchet is named after the Xiangyang cannon. "

Xiao Yuan moved out the historical materials and gave Lao Liu the origin of the Xiangyang cannon to Lao Liu.

To put it bluntly, this thing is actually using the principle of leverage, on the basis of ordinary trebuchets, and adding a counterweight device.

But this kind of weapon, which seems to have little technical content in later generations, will not appear until at least a thousand years later, and moving it out now is tantamount to a dimensionality reduction strike.

Although Zhang Fei was ignorant, he could vaguely hear that Xiao Yuan was explaining history again.

Chen Deng, Zhuge Liang, Zhang Liao and other military generals who strategized and ministered, but they listened with big eyes and small eyes.

Everyone counted on their fingers, there was no such dynasty as Mengyuan in ancient times?

And what else is Eurasia, and what is it?

Why is the thing on the picture related to Xiangyang?

The more people listened, the more mysterious they became, and their minds were a mess.

"The meaning of the Changsu military division is that he wants me to build this Xiangyang cannon to break through the Shouchun city wall!"

Liu Bei comprehended Xiao Yuan's intentions, and his eyes were suddenly pleasantly surprised.

"That's right, that's what I meant. "

"Xiangyang City is made of bricks and stones, and it can't resist this Xiangyang cannon, let alone Shouchun City, which is built of earth. "

"The lord built seven or eight of his Xiangyang cannons, and I estimate that it is enough to collapse the city wall. "

Xiao Yuan's face was confident in controlling everything.

Liu Bei originally doubted whether this Xiangyang cannon was so powerful, but when he thought that it was taken out by Xiao Yuan, he no longer had any doubts.

This thing must be an artifact, just make it!

At that moment, Liu Bei gave an order to gather craftsmen in the army to build Xiangyang cannons overnight according to the drawings given by Xiao Yuan.

The military discussion ended in an atmosphere of suspicion and Liu Bei's excitement.

When Xiao Yuan returned to the tent, as soon as he lifted the curtain, a fragrance came to his face.

Mi Zhen, who was dressed as a man, had been waiting in the tent for a long time, and the table was full of wine and food.

Xiao Yuanqi said: "Brother is here, what kind of wind blew you to the front line?"

Mi Zhen lied that she was a grain officer, and she had just transported grain and grass from Xiapi to the front line of Shouchun.

The grain and grass logistics affairs in the army, Lao Liu was relieved to hand over to the Mi family to take care of, and Xiao Yuan didn't think much about Mi Zhen's reason.

"The front line is not as good as Xiapi, and all you want to eat is coarse tea and light rice. "

"I was afraid that Xiao Junshi would not be used to eating, so I asked the accompanying cook to make some wine and food for Xiao Junshi, and Xiao Junshi took advantage of the situation to eat. "

Mi Zhen pointed to the wine and meat on the table and explained her intention with a smile.

"The Mi family is rich in the world, and it really is not built, brother, you still have a cook with you, pay attention to it!".

After Xiao Yuan admired it, he smiled and said, "Then I'll touch your light, brother, I'll wash my hands first." "

As he spoke, he picked up the soap that Tufa had made and wiped his hands.

"Xiao Junshi, you are..."

Mi Zhen saw him use a piece of wax-like stuff to smear back and forth on his hands, and couldn't help but be full of novelty.

"What, don't you wash your hands before eating?" Xiao Yuan asked rhetorically.

"No, no, no, of course we wash our hands. "

Mi Zhen pointed to the soap in his hand, "I'm curious, what is in Xiao Junshi's hand, how is it like wax, and foam comes out when you wipe it on your hand, it's really amazing." "

"You thing. "

"This thing is called soap, it can sterilize and disinfect, and I am more hygienic, so I made a piece of it myself. "

"Why don't you wash it too?"

Xiao Yuan stuffed the soap into her hand as he spoke.

Mi Zhen held it in her hand, but she was a little overwhelmed and didn't know how to use it.

"It's simple, I'll teach you. "

Xiao Yuan grabbed her bare hand and helped her make soap.

It's the first time in my life that a man grabbed his hand and touched it like this.

Mi Zhen's heart suddenly pounded, and her face was dizzy.

"Brother, why are you so red?".

Xiao Yuan became worried, and without saying a word, he raised his hand and touched her forehead.

Mi Zhen was only a little embarrassed, and when he tried his forehead like this, he suddenly blushed to the root of his ears, and his forehead was hot.

Xiao Yuan was startled: "Good guy, your body temperature is at least 39 degrees, Brother Mi, you have a cold and a high fever!"
