People wrote diaries in the Three Kingdoms, and Cao Cao became paralyzed.

"Good!"

Cao Cao replied and added

"Zixiao is not bad in their hearts, but they have always been children of the family, and they also have some temper of the family."

"Before they didn't know what your second brother was capable of, don't see them in general."

Lin An shook his head with a smile

"How come, they are straightforward and very cheerful."

"In addition to the three things you have seen, big brother, I also have a horseshoe called a horseshoe, which can be nailed to the horseshoe."

"Horseshoes!"

Cao Cao's eyes lit up again, coming.

Immediately asked:

"And what is this horseshoe? Nailed to the horse's shoe, will it affect the horse's speed? "

Lin An explained:

"There is an impact, but it is a good effect."

"It's actually an iron ring around the horseshoe."

"This protects the horseshoe from wear and tear and at the same time improves the grip of the horseshoe."

"Let the horses be more powerful, more stable and probably faster when running."

"Just like people wear shoes, with a good pair of shoes, it is faster and more comfortable to run."

After listening to this explanation, Cao Cao immediately understood, and quickly said:

"Well, if it's really what you say, it's a good thing to hold."

Lin An nodded

"I'll draw all the drawings later, you find a craftsman to build it, and you can experiment first to see what the effect is."

"Good!"

Cao Cao stood up excitedly.

Now he is a little impatient.

This is a study, and everything you should have is there.

Lin An did not delay and began to draw the production methods of crossbows, stirrups, saddles and horseshoes.

There was also a sleeve arrow, but Lin An did not draw it.

That thing is used for self-defense, and if the soldier is equipped, he has to modify the armor, and increase the weight on the body, which is not suitable for use in the army.

Soon

A few drawings were drawn by Lin An.

At the same time

Lin An thought of something again, took another piece of paper out, and began to write again.

It took a while before it stopped.

"This is..."

Cao Cao was full of curiosity.

This time it's not a drawing, it looks like some trick?

Lin An explained with a smile

"These are several ways to increase the physical fitness of soldiers, and soldiers are recruited and trained according to this method to improve the basic physical fitness of soldiers more effectively."

"This..."

After Cao Cao listened, his spirit suddenly shook again.

Quickly picked up the paper in front of Lin An, and looked at it carefully as if he had obtained a treasure.

Ways to train soldiers and improve their basic physical fitness.

This is a real baby.

Ordinary people hold it in their hands and keep it as a treasure, but Lin An actually took it out so easily?

Of course

If Cao Cao knew that these were just the introductory methods in the encyclopedia of basic physical training methods, he would probably drop his jaw in shock.

There are many more efficient ways.

Cao Cao held it in his hand, a little excited.

If he has an army of 100,000, no, an army of 50,000 will do.

If all these things are equipped, what will be the alliance with Dong?

He alone could destroy Dong Zhuo.

It's just a pity

There aren't that many people now.

Finish drawing the drawings

Lin An then took his leave with Cao Cao

"Big brother, you go first, I have something to go out of the house."

Cao Cao asked curiously

"What's going on?" If it's a trivial matter, let Cao Fu do it. "

"Your identity is different now, and you don't have to be polite with the people in the house."

Lin An thought about it, but said truthfully

"I'm not free now, although my eldest brother's family is my family, but after all, there are still some differences."

"I wanted to go out and buy a house and make a place to stay."

"Buying a house?"

Cao Cao paused, just wanted to refute Lin An's use.

But think about it, Lin An was a subordinate of the family before, and now that he has regained his freedom, he should indeed have his own home.

Direct way:

"You really deserve your own mansion."

"But you don't have to go in person."

"I'll tell my father later, let Cao Fu arrange it."

"Moreover, with your connections, it is still a little difficult for people to sell you a better house."

“......"

This last sentence is a bit heartfelt, but it is also a reality.

Lin An was helpless, but he also agreed, and instructed: "Then by the way, let the housekeeper help me buy a few acres of land, it will be better." "

"Ground?"

"What are you going to do with me to buy land?"

Lin An smiled mysteriously, but did not explain much, "You'll know then." "

"Good!"

Cao Cao agreed, but did not care too much.

After all

How many acres of land, what can be done?

"I'm still going to go out and buy something."

"Good!"

This time, Cao Cao didn't stop him, he just didn't want Lin An to worry about these things, and he didn't want to detain Lin An in the mansion.

Moreover

With Lin An's drawings, plus the preparation for recruitment, he also had to be busy.

But right away

Cao Cao thought of something again, and looked at Lin An, who had left the study, and quickly shouted again:

"Hey, come back quickly after shopping, you have to help me."

Almost forgot

Lin An is now his sworn brother.

So many things are waiting for him, how can Lin An be a handshaker?

"Say it again."

Lin An waved his hand.

Help?

That's impossible to help.

It's okay for him to move his mouth, to speak at length, with the thinking and knowledge of a traverser, and it is okay to talk.

But if it comes to small things.

There are a lot of things he really can't handle yet.

Moreover

This kind of work is tired and annoying, and he is tired of planning and working?

This kind of loss-making trading is why he does not do it.

“......"

"This kid!"

Seeing that Lin An had already walked away, Cao Cao shook his head helplessly.

Yet

Looking at the few drawings in his hand, plus those he had chatted with Lin An before, Cao Cao's gaze became more and more firm.

Dig deep holes, accumulate grain, build high walls, and slow down the king

Can it really be done?

...

All the way out of the Cao Mansion, Lin An went to the street to buy a lot of things.

It is mainly the equipment that may be used in mechanical surgery.

Previously, he promised Cao Ren and the three to personally make three crossbows and give them to the three, and he himself had to keep at least two for self-defense, which was five in total.

Although it was possible to wait for Cao Cao's side to arrange craftsmen to make it, he finally agreed to the people's affairs.

Moreover

What he made himself must be better than the ordinary craftsmen he found.

Keep it for your own self-defense, it must be the best.

And then there's the new thing he's going to build.
