After letting Li Chunfeng rest for a few days.

Lu Heng instructed him to get the manuscripts out of him.

All of them were classified, and a total of four textbooks were compiled into a total of four textbooks with suitable difficulty.

They are the upper and lower volumes of mathematics and geometry and algebra.

From Lu Heng's point of view, although these books are for many people in this era.

It's already the most advanced way of arithmetic.

But in addition to the most profound ones, in the later life, it is basically what you have to learn before high school.

So even if it's a little difficult for students to learn.

However, it should still be within the acceptable range.

It just so happened that the basic mathematics course that Lu Heng made up for the academy is now using.

In another month, I will be able to teach about the same.

So Lu Heng directly asked Li Chunfeng to open a class in the academy.

Started training these math teachers who are currently on the job.

According to Lu Heng's estimate.

It can be difficult for these teachers to fully grasp this knowledge.

But as long as you have studied the ten books of the Sutra before.

Most of them are still quick to use.

So when the time comes, we will do a specific job scheduling.

In addition, let Li Chunfeng increase the scale of training.

By then, we should still be able to make up enough math teachers.

When things in the academy are almost straightened out.

Lu Heng was about to get up and leave Chang'an City again.

He's going somewhere else this time.

is going to personally go to the mine that Li Ergang approved for him to have a look.

After all, he wants to greatly increase Datang Iron and Steel production.

So I had to go and see it for myself.

Although Li Mingyu was reluctant to part with him.

It's just that she herself is now studying in Sun Simiao's medical class.

The daily school load can be called overwhelming.

So I can't pull away anyway.

In the end, he could only simply let Wu Zhao, who was going to go with Lu Heng, take care of his daily life.

As for security, Li Mingyu doesn't have to worry about it now.

Because there were not only officers and soldiers from the western suburbs who accompanied Lu Heng.

Even Wang Xuance and Zheng Yang and others who had just made miraculous achievements in the frontier.

Because it's really boring to stay in Chang'an City now.

So I will also follow along to rise and gain knowledge.

There is such a group of strong men who can fight against a thousand by their side.

I believe that there is no one who dares to provoke Lu Heng without opening his eyes.

With a mighty crowd of people, Lu Heng left Chang'an City and went all the way to the east.

After passing through Xianyang, the capital of the pre-Qin Dynasty, he finally entered the boundary of Qizhou.

According to Lu Heng's estimate, it should be near Baoji in later generations.

Rested for a day in the city of Qizhou Prefecture.

Early in the morning of the second day, Lu Heng once again led the mighty team.

Go straight to the iron mine, which is not far northeast of the state city.

Until all his own teams left Qizhou City.

Wang Xuance looked back at the city behind him and scolded bitterly:

"This Qizhou Prefecture is really big-faced, we have been in the city for one night, and we haven't seen him come out to take a look."

Lu Heng remembered the stammering of the county magistrates along the way.

I couldn't help but laugh at him and said, "What? I've seen a lot of smiling faces along the road, and now that people don't come out to slap you with two sycophants, are you still angry? ”

Wang Xuance shook his head, "Why do you laugh at me, donkey? We haven't taken advantage of anyone along the way. ”

"No matter what state or county you are in, food and accommodation are all out of your own pocket."

"It's just that this Qizhou assassin history is too deceitful, so I just said two sentences."

Wang Xuance is not wrong in what he said, in the final analysis, in the name of Lu Heng now.

No matter where they go in the world, these Datang officials should come out to say hello.

Like the history of Qizhou Thorn, Lu Heng has stayed in his state city for one night.

I still didn't even say hello.

That is somewhat of a deliberate drop on his Lu Heng's face.

However, in this regard, Lu Heng is very open.

After all, although he is now a big celebrity in front of Li Er.

But there are so many people in this world, it is not surprising that there are people who don't like his status as a relative.

So don't blame the other party for this.

Although when he went out of the city, Lu Heng was still quite relaxed in his heart.

But when he arrived at the mine with his people.

In his heart, he not only had some anger towards this thorn history in Qizhou.

After all, Lu Heng can ignore the problem of face.

But what Lu Heng wanted to do was something that no one could delay.

Lu Heng said to Zheng Yang beside him with a straight face:

"You can take my roster back to Qizhou City now."

"Call that assassin in the city and I'll ask him!"

According to the last deliberation in the court.

Li Er had already issued an edict to notify the various mines in Datang.

It is not only necessary to remove the prisoners who used to work in the mines.

It is also necessary to actively recruit people from all over the country to work in the mines.

And Li Er also directly stated it in the edict.

The states and counties at all levels were required to pay the wages directly to those who had entered the mines to work.

At that time, the imperial court will also rely on the iron ore produced by their respective mines.

Pay them an extra amount of money.

This is tantamount to allowing these places to recruit people to work in the mines.

The excavated iron ore was then packaged and sold to the central court.

So all states and counties can actually benefit from this.

But what Lu Heng didn't expect was this.

The iron mine in front of him now.

The prisoners who had been working in the mines were all gone.

But there is not even a shadow of a single recruited citizen.

The whole iron mine, except for the tools scattered on the ground.

It's a few officials who are watching over again.

It can be said that it has completely come to a standstill.

This made Lu Heng couldn't help but look angry in his eyes and in his heart.

If you want this iron ore to be well managed.

Then you Qizhou Thorn Shi didn't come to meet yesterday, and Lu Heng wouldn't have come to look for you.

But not only did you not come to take a picture now.

also deliberately wanted to directly stop the iron mine that Li Er designated to hand over to Lu Heng.

Then Lu Heng really thought about it, did you, the Qizhou assassin, really want to fight against him Lu Heng!

Lu Heng and his party waited outside the iron mine for Zheng Yang to pass the word.

But what no one expected was this.

After almost half an hour, Zheng Yang, who was running back on a horse, said to Lu Heng:

"Master Pony, I haven't seen anyone."

"Huh?" Lu Heng turned his head and asked in a cold voice, "What is the specific situation?" ”

Zheng Yang glanced at Qizhou City in the distance with some helplessness, and said:

"I don't know, now the four gates of Qizhou City are closed, and no one is allowed to enter or leave at all."

"I asked outside the city gates, as if it had been since we left the city."

"The gates were sealed."

"What a bold man!" Hearing Zheng Yang's answer.

Lu Heng couldn't hold back his anger anymore.

Directly turned his head and shouted to the officers and soldiers of the western suburbs battalion that he had brought with him:

"All in line! Come with me! ”

After speaking, Lu Heng took the lead, and returned to the city of Qizhou with hundreds of officers and soldiers of the western suburbs under his command!
