It's really nice for you to say that to my face!

Unknowingly, he walked to the innermost cell where Hua Tuo was held.

I saw a white-haired old man sitting on a straw mat inside.

I don't know if it's because of Guo Jia or full of favors.

Hua Tuo was not injured, except for his face that was a little ugly, everything else was fine.

"But I'm here to send the old man to the execution ground!" Hua Tuo raised his head slightly and looked at Cao Yu.

"Definitely! Hua Shen Doctor is famous all over the world, how can he die in prison. Cao Yu immediately opened the door of the prison and bowed deeply.

In this way, Hua Tuo's face is slightly better-looking.

"Is there a patient who needs to be healed by an old man?"

Hua Tuo, who is old and sophisticated, sees the other party's two extremely poor attitudes, and he doesn't need to think about it to know that he must have something to ask for himself.

But in the next second, Cao Yu's answer made him dumbfounded.

"I don't have to have a patient who needs to seek a Chinese doctor, but I want to help a doctor." Cao Yu smiled faintly.

"You said you wanted to help me?" Hua Tuo was shocked, and then felt a little funny.

"I Huatuo is not greedy for money or fame, I don't know if I need your help with anything, if it is to save my life, I don't have to!"

The Sacred Heart of the Healer has long regarded his life and death as far away.

So if Cao Yu's help was to get him out of prison, he didn't care at all.

"Hahaha, it deserves to be a Chinese doctor, a good life and death."

Hua Tuo was even more sure that Cao Yu was going to help him get out of prison.

However, in the next second, he was completely dumbfounded.

"I don't want to help you get out of prison, but to help you fulfill your long-cherished wish to help the people of the world."

Well?

Hua Tuo was shocked.

How did he know the old man's wishes.

Cao Yu's voice continued.

"But even if you use all your strength and run to every corner of the Shenzhou Continent, you won't be able to save the people of the world."

"Huh?" Hua Tuo frowned slightly, although he didn't like it, he had to admit this fact.

"You have a way to help the world."

If it was just to sarcastically mock him, Hua Tuo decided not to bother with the kid in front of him anymore.

But he didn't expect Cao Yu's next sentence to completely shock him.

"A certain Cao Yu has his own way to help the public, he only needs to open a medical school, and Hua Shen Doctor has taught him and cultivated tens of millions of children, why should the people of Shenzhou worry about being sick and having no doctor!"

Hiss!!!

As soon as the voice came out.

Even the full pet next to him was dumbfounded.

Especially the aura of overlord that Cao Yu exuded just now.

It almost made him feel like he wanted to kneel.

Swallowed his saliva and stared at Cao Yu's side face.

And Hua Tuo, who was sitting on the straw mat, was even more shocked.

Medical!

Ten million disciples!

What a big breath!

The bowl in his hand suddenly fell.

It slammed into the ground with a crisp sound.

This brought the two of them back to their senses.

"Yingchuan College has not popularized reading, why do I believe that you can popularize medicine, and no one will want to study medicine!"

Speaking of the last point, Hua Tuo's eyes were a little gloomy.

In troubled times, they all want to be generals.

Sheng Shi wants to be a powerful minister.

Ten years of cold window Coco has gained fame and gained fame, and it has become a step forward.

Ten years of studying medicine, but he can be a doctor.

Who wants to be a powerless healer?

"There will be people who want to, and I will put them in the official register."

Cao Yu stood with his hands on his back and looked up.

Look at a spider in the corner who is really building a web.

The light of the cracks in the walls of the cells is put in.

Hit on the cobweb, especially dazzling.

Then Cao Yu pulled out the sword at his waist and cut through the cobwebs with a sword.

The net, which was originally connected into a surface, instantly broke a big hole.

But the spiders are still weaving their webs.

Cao Yu stretched out his hand to remove the spider silk from the blade, compared it to the sunlight in the gap, and said lightly.

"The moment the spider spins the silk, I don't know what will happen to the web, and no one knows what the result will be until the last moment."

"Here you can only believe me!"

Thundered!

Cao Yu's domineering voice resounded in the cell, shattering Hua Tuo's heart like thunder.

I don't know why, obviously looking at such a young face.

Hua Tuo suddenly had a feeling of being willing to believe him.

It wasn't until halfway through the ring that he came back to his senses.

"Are you really willing to build a medical school?" Hua Tuo seemed to want to affirm again.

"If Doctor Hua Shen is worried that there will be external obstruction in the construction of the academy, then you can rest assured, I have already received the support of the prime minister."

As soon as these words came out, Hua Tuo completely relieved himself.

Although I don't like Lao Cao very much, being able to do such a big thing for the people of the world is nothing, even if I am wronged.

"Grass people Hua Tuo is willing to join!"

"Divine doctor, please hurry up, you will be the head of the academy in the future, but there is one more thing I need your help with!" Cao Yu hurriedly pulled up Hua Tuo.

"I don't know what?"

"Actually, it's still about the academy, and you also know that you teach alone, and there are still a few teachers after all, just like asking if you can find some people who are willing to come!"

Cao Yu sat on a chair next to him and said lightly.

"That's no problem, the old man immediately wrote to my disciples, asking them to come over and teach together, and a few friends, I believe they are also very willing to come."

As soon as he heard this, Hua Tuo hurriedly patted his chest and reassured.

In this way, it is related to the faculty of the medical school, which is basically solved.

Cao Yu watched Hua Tuo leave, thinking that he had nothing to do, so he planned to go and see how Sima Yi's salt refining field was.

……

The sky was clear and cloudless.

On the outskirts of Xudu, a deserted factory.

I saw dozens of red-clothed men, carrying bamboo baskets full of salt ore.

There were also two young men in brocade robes above.

"Lord, you sit, the current salt factory, the basic materials have been collected, but ......"

After finishing speaking, Sima Fu looked a little speechless and stopped.

"What's the problem?" Cao Yu sat on the chair and raised his head to look at Sima Fu.

"No, it's just my lord, can this brine really be made into salt? I've heard this thing is poisonous! ”

Sima Fu was worried that it would be fine if this thing couldn't be done.

If it poisons someone, something big happens.

Sima Yi next to him also raised his eyebrows slightly, and he was also a little worried.

Just when the two were worried, Cao Yu suddenly laughed.

"Hahaha, I thought something was going on." Cao Yu got up and patted Sima Fu on the shoulder, and then said with relief.

"Rest assured, there is absolutely no problem with this salt, and even its taste is far superior to the best North Sea fine salt on the market today."

What?

The salt made of this broken stone surpasses the fine salt of the North Sea?

Sima Fu and Sima Yi were shocked at first, and then their faces were full of disbelief.

If you want to say that it's not poisonous, I'll believe it for the time being.

But if you want to say that the quality is better than the North Sea salt, you are exaggerating.

It's a poisonous broken stone.

"What, don't you believe it?" Cao Yu knew what the other party was thinking when he saw the expressions of the two.

"Ahem, ahem...... No, no! Sima Fu immediately shook his head and touched his nose.

Knowing that no amount of explanation can be straightforward from the facts.

Cao Yu didn't explain more, so he went into the factory to see.

At present, the yard is already full of salt ore.

Under the refraction of sunlight, it looks like a jewel.

It's all white money.

Walking forward, Cao Yu picked up a piece, and the corners of his mouth couldn't help but rise.

The ancients said that if you can control the salt vein, you control the lifeblood of the country.

And now almost all the salt mines within a radius of Xudu have been bought by him.

As long as he waits for the first batch of fine salt to be born, it will be when he is rich and rivals the country.

"Xiao Yu, I have already drawn the grinding machine drawings you want."

At this moment, Mozi suddenly sounded in his mind.

"Thank you, Mr. Mozi."

Hearing that the machine was about to take place, Cao Yu's hand held the salt stone a little tighter.

"Hey, Yu boy, is there really no problem with your salt-making method?"

"If you eat the dead at that time, I'm afraid Lao Cao won't be able to save your life even if he wants to."

The First Emperor couldn't help but shout.

"Of course it's fine, why don't we make a bet?" After speaking, Cao Yu's eyes rolled as he spoke.

"What bet? I only have one soul left, what else can I bet with you? The First Emperor was a little puzzled.

"As long as you lose, tell me the secrets of your tomb!"

In later generations, although I went to Xi'an to see the terracotta warriors and horses, I did not see the main tomb of the first emperor.

Thinking that the outside is so magnificent, the main tomb must not be more splendid.

I was very curious, but every time Cao Yu asked, the First Emperor avoided answering.

seems to be afraid that this kid Cao Yu will pout his grave in the past.

This is still the case.
