Du Rufang didn't pay much attention to it, but then listened carefully for a moment, and then his mouth opened slightly.

He had to admit that the equation that the other party said was extremely useful and could get the answer very quickly!

"Brother Lu, you taught this student?"

The student who was the leader just now kept talking about Mr.

In the qualified valley, if you want to say that arithmetic is extremely powerful, this seems to be the Lu Chensheng he knows.

He had seen it before, and he had also seen the other party's attainments in arithmetic.

"Well, it looks like this student is doing pretty well."

Although at the beginning, I saw that the other party was angry for a moment, but then I explained it carefully, and it was quite a set, and what I said was extremely easy to listen to.

Lu Chensheng listened on the side, nodding again and again in his heart.

Du Rufang was shocked.

How can this be done, teaching a child so well that it can be taught to the rest of the students!

He felt that if he tried to solve the problem with the other party, he was afraid that he would not be able to beat this child, and when he thought of this, he suddenly felt a little embarrassed.

"Brother Lu's attainments in this arithmetic, I'm afraid that no one can match it, right?"

Du Rufang calmed down for a while, looked at the children who were still teaching students in the distance, and then said with a wry smile.

At this moment, the other party's explanation has become his immovable knowledge again.

He just vaguely heard something, it was physics or something, and then he talked about words like ice cube sublimation, all of which were words he didn't understand.

Du Rufang suddenly felt that he was so short-sighted.

"It's just a little bit of it."

Lu Chensheng shook his head when he heard this, he only knew a little bit about his studies, and if he really wanted to talk about some esoteric math problems, Lu Chensheng would stop cooking.

However, in the arithmetic world at this time, Lu Chensheng is more or less at the forefront.

Lu Chensheng said this, but Du Rufang didn't believe it.

Just look at the students on the side, aren't all the things they learn taught by Lu Chensheng?

The topics that were originally extremely difficult for them can now be easily solved here, which can show how deep Lu Chensheng's attainments in arithmetic are.

Lu Chensheng was modest, he didn't say anything, just looked at it from the side and continued to walk to the side with Lu Chensheng.

"Ai, you can't go here."

Seeing that Du Rufang wanted to go to the workshop, Lu Chensheng immediately stopped him.

In the workshop over there, there are a lot of secrets, and Lu Chensheng can't take the other party over at will.

Du Rufang is not Lu Chensheng's person yet, and he will return to Dacang Kingdom in a short time.

let the other party see some of the secrets inside, and turned around to make the same workshop again in Dacangguo, but it was Lu Chensheng who was unlucky enough to suffer.

Du Rufang was stunned when he heard this, and glanced at the distance curiously.

In front of them were workshops, some of which were emitting black smoke, and there were extremely tight guards outside.

It can be seen that Lu Chensheng attaches great importance to this place, and the soldiers outside do not seem to stop at all, staring at the people who come and go sternly.

What could be in this, so well guarded?

Du Rufang was a little curious, but he didn't ask to see it.

After nodding at Lu Chensheng, he changed directions.

But there is nothing to see in the rest of the place, it is just some construction sites.

After Du Rufang thought about it, he went up to the city wall with Lu Chensheng.

The walls on the mountains, he was still quite curious.

In addition, the castle wall offers a bird's-eye view of the entire valley, which is a great viewing spot.

The two of them went up to the city wall, and at this moment there were already soldiers guarding the city wall.

Seeing a stranger coming up, but Lu Chensheng didn't ask anything when he was around.

"Originally, looking at this city wall from the bottom of the mountain, I already felt that it was magnificent, but now when I came up, I felt more and more majestic."

Du Rufang looked left and right, and then sighed and said.

He did feel a sense of powerlessness over the wall in front of him.

If he comes to attack here, he is afraid that it will be difficult to take this place if he comes.

In this way, the city wall can already bless this place without worry.

"The walls are majestic enough, but they need to be guarded by soldiers."

Lu Chensheng smiled when he heard this, and walked on the city wall with the other party for a while, and then went down the city wall.

At this time, it was time to rest, and the food was also carried up.

Du Rufang looked at the sky, it's not evening yet, what's the matter?

"This, why is it that I see them resting and eating at this moment?"

Du Rufang was puzzled, looked at Lu Chensheng on the side and asked.

"Oh, it's just for them to take a break, and it's a long afternoon, and they can eat something to replenish their strength."

When Lu Chensheng heard this, he waved his hand casually and said.

Four meals a day, it's already a habit here.

Du Rufang looked surprised, this is too good!

Ordinary people, basically, they have two meals a day, and they can't afford to eat three meals a day, but now they can eat four meals when they come to Lu Chensheng?

It's no wonder that the people on the side are full of joy when they are working.

In these days, sometimes it's good to have a bite to eat, how can you ask for so much?

"No wonder, more and more people have come here recently, so if everyone knows about the treatment, I'm afraid the number of people who come here will have to double."

In terms of current traffic, many of the other parties are ill-informed.

Recently, the number of people coming here has increased a lot, and the number of merchants who come and go has increased.

These businessmen will bring some news out, and some people will come here to see it.

Others are skeptical.

If you really know it, you can eat four meals a day while working here, and there will be a lot of people who come here.

"Brother Du also cares about the people when he comes back, and when he goes back, he can help persuade those people who are about to be unable to live, come here to take a look, how to say that there is still a bite to eat here."

When Lu Chensheng heard this, he said to Du Rufang.

There are so many people who can't eat, but some people don't believe that they can eat here, so there are many people who don't come here.

If Du Rufang can help talk, there will be a lot more people who want to come.

After all, in Du Rufang's identity, there is no one who would not believe what the other party said.

The champion of the dignified Cangguo, this reputation is still there.

Du Rufang nodded when he heard this, he didn't mind helping to say that the people who came here were treated so much, and it was a good thing to let some people eat a mouthful of food.
