The next day, Cao Shuo got up early in the morning.

When Qingwu washed, he squatted beside the bed, folded the sheets neatly, and put them in the baggage.

"What is Childe doing with that?" Seeing Cao Shuo put the sheet into the baggage, Qingwu asked.

"There's the mark of your first time." Cao Shuo said: "Of course, it must be preserved. ”

Qingwu's cheeks flushed: "Childe has benefited, and he is still begging for cheapness, it's so annoying!" ”

"I thought you had always been cold and didn't know how to be coquettish." Cao Shuo smiled: "Now you are like a real woman." ”

Qingwu ignored him.

has a certain understanding of Cao Shuo, and she knows that no matter what she says, Cao Shuo can find a high-sounding reason.

What's worse is that she knows it's a fallacy, but she can't justify it at all.

"Childe." Sima Yi's voice came from outside the door: "Are you up?" ”

"Get up, come in." Cao Shuo commanded.

Sima Yi entered the house, and when he saw that Qin Nu was also there, he clasped his fists and saluted, and then saluted Cao Shuo and said, "I have prepared the things that the people and the entourage will bring." ”

"Thank you for your hard work." Cao Shuo said: "In addition to what I told you yesterday, there is one more thing that you have to help me do. ”

"Childe, please command." Sima Yi said.

"The undead camp lacks war horses." Cao Shuo said: "You go and buy a batch of horses, and then find a blacksmith to build these two things, and when I return to Xudu, I will equip the soldiers." ”

Cao Shuo took out two drawings that he had drawn a long time ago.

Taking the drawings, Sima Yi glanced at it and asked in amazement: "Childe, ...... is this?"

"I've marked them all on the drawing." Cao Shuo said: "What materials are used for each part are also clearly written. One of them is called a stirrup, with which the soldiers of the undead battalion can be equipped with heavy armor and charge from the front. Another short blade that looks like an angular one is called a triangular military thorn. It has a deep blood groove that stabs into a person's body, and even if there is a wounded doctor around, there is a chance that it will not be able to save it! ”

Cao Shuo had people make gym equipment and daggers earlier.

The repeating crossbow had been proven on the battlefield, and Sima Yi was even more convinced that what Cao Shuo had designed was a divine weapon on the battlefield.

"Childe always has a whimsy." Sima Yi said: "If these two things are equipped in the army, the soldiers will definitely be like fish in water on the battlefield." ”

Cao Shuo used to be a special soldier, not to mention cold weapons, even if he was given a rocket launcher, he could disassemble it and install it.

If gunpowder and even guns could be made in this era, his immortal camp would be invincible.

Unfortunately, these are just ideas, and they will probably never be realized.

The recipe for gunpowder required saltpeter and sulfur.

Although these two things can be obtained, the purification process has not been reached, and the gunpowder made is impossible to use on the battlefield.

Not to mention the guns.

During the Eastern Han Dynasty, although the iron-smelting industry was relatively developed, it was a difficult problem to refine steel.

Not even pure steel could be refined, let alone the seamless steel pipes needed to make guns.

Even if the seamless steel pipe is not made directly from a mold, the welding method requires electricity first, then acetylene and pure oxygen, which are melted at high temperatures and then carefully polished.

Electricity, acetylene, pure oxygen......

Inventing these things in this day and age......

Cao Shuo didn't even dare to think about it!

Although he knew about the existence of these things, he could even disassemble and put on the most complex guns in a very short time with his eyes closed.

But after all, he is only a special soldier, not a scientist.

To solve the fundamental problem, it is necessary to accumulate the wisdom of generations of craftsmen.

A long-term process that cannot be solved in a day or two.

The only thing Cao Shuo can do is to leave his ideas and let future generations invent high-tech products according to his ideas, so as to achieve national prosperity and strong people, change history, and erase the humiliation of the Chinese nation being bullied.

"I'm well-read, and of course I've got a lot of ideas." Cao Shuo said: "You should also read more books in the future, don't just read some art of war and the way of governing the world all day long." Some popular science books are also good. ”

"Popular science books?" Sima Yi blinked his eyes twice in a daze.

"It's just books with fantastic ideas." Cao Shuo waved his hand: "Forget it, I won't tell you, it's time for me to set off!" ”

Cao Shuo's words confused Sima Yi.

Especially the words "popular science books" made him even more confused.

The more this is the case, the more he feels that Cao Shuo is amazing!

It seems that Childe has not been serious all day long, but he has more wisdom in his chest than anyone else.

At least there are many books he has read, Sima Yi thinks he has never read......

How did he know that before coming to this era, Cao Shuo's favorite thing to read was actually some idle books that were not nutritious.

Except for those idle books, it's just flipping through magazines.

As for the art of war or something, he really hasn't studied it.

With troops on the battlefield, Cao Shuo only relied on tactics to win.

The strategy of controlling the overall situation, he really can't do it!

Chen Wu and Liu Shuang had already brought more than 20 guards to Yuanmen.

Seeing Cao Shuo coming, everyone stepped forward to salute.

"So many people?" Cao Shuo smiled: "We are going to do errands, not to fight wolves." ”

"Isn't Childe going to intercept the daughter of the Lu Bu family?" Sima Yi said: "It will not be wrong to bring more people." ”

"That's right." Cao Shuo said: "It's very simple to intercept people, in fact, you only need five or six helpers. ”

"The Huainan army that escorted Lu Bu's daughter has two or three hundred people, to say the least." Sima Yi said: "I still think these people are not enough! ”

"You can't take all the undead camps away." Cao Shuo said: "That kind of goal is too big, and others will see through what you want to do before you do anything." ”

"Childe is good at winning more with less, and I am very convinced." Sima Yi said: "But please be careful, the Huainan Army is not a straw bag and rice bag under Zhang Xiu!" ”

"So what? Can it be compared to my immortal camp? Cao Shuo got on his horse and asked Chen Wu, Liu Shuang and others: "Answer me, how many Huainan troops can be killed by twenty immortal battalions?" ”

"Two thousand!" Chen Wu shouted at the top of his voice.

"Good! I just like the way you pretend to be forced! Cao Shuo laughed: "When I am a soldier, I must not only dare to blow up the, but I must be able to do it after blowing!" ”

"Let's go!" He shook the reins and turned away.

Qingwu and the others followed closely behind and walked out of the barracks.

Sima Yi stood at the gate and did not return to the barracks until the backs of Cao Shuo and the others disappeared at the corner of the street.

Cao Shuo arranged a lot of things, and before he came back, Sima Yi didn't have time to be idle.

"Captain Sima!" As soon as he entered the barracks, Wei Yan greeted him and asked, "Childe is gone?" ”

"Gone!" Sima Yi said: "Gongzi arranged a lot of things for me, and the training soldiers had to trouble Captain Wei to cooperate with Cai Ji and Wei Tu. ”

"Since you voted for Gongzi, of course you have to make an appearance." Wei Yan said.
