This water dragon is one of the most important resources in the valley.

The water in the valley will depend entirely on this water dragon.

With this water dragon, there is no need to worry about water shortage in future farming, and people and livestock do not have to worry about water shortage.

If you have enough food, you can be self-sufficient without worrying about being besieged.

Du Rufang, who was on the side, looked at the gushing water column, and his face also brought a touch of surprise.

"There is still such an abundant water source in this valley, you really chose the right place, if you expand the cultivation land, even if you don't have to buy food, it will be enough, right?"

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

There are more than 10,000 acres of land on the side, which have been planted with rice.

He looked at it clearly on the side, there are quite a few people in the valley now, but if Lu Chensheng expands the area of cultivation, it is still possible to be self-sufficient.

"yes, it's just that it's still experimental."

Lu Chensheng didn't deny this sentence, the valley is so huge, even if millions of people live, there is still enough area to cultivate.

However, now that there are too few people, and the rice fields are still experimenting, Lu Chensheng has to figure out a more suitable fertilization plan.

If it can be completed, the area under cultivation will be expanded by then, and by the way, it will be possible to expand the manpower a lot next year, and it will be enough to expand the area under cultivation by then.

If you have a curved plow, plowing is quite easy, and you don't have to worry about the difficulty of plowing temporarily.

"Experiments?"

Du Rufang listened to what Lu Chensheng said, and glanced at Lu Chensheng with a little confusion, not quite understanding what Lu Chensheng meant.

"I'm experimenting with how rice can increase yields."

When Lu Chensheng heard this, he opened his mouth to respond.

Du Rufang was stunned when he heard this, "Isn't this that as long as the wind and rain are smooth, you can have a bumper harvest?" ”

"It's as simple as that."

Lu Chensheng shook his head when he heard this, if this thing was as simple as that, it would be good.

The wind and rain are smooth, and you are afraid of the strong wind in the valley? The water source is also extremely abundant, so there is no need to worry about these two problems.

After the natural factors have been eliminated, the next step is to see the effect of this fertilization.

When it comes to increasing rice yields, Lu Chensheng naturally thinks of hybrid rice.

It's just that this hybrid is not so simple, and it is necessary to find natural male aborted rice.

This kind of rice is extremely difficult to find, which is equivalent to a martial arts wizard that is rare in a hundred years.

If you find it, you will have to carry out continuous hybridization when the time comes.

It's too difficult, and in today's situation, Lu Chensheng really doesn't have the manpower to find such rice everywhere.

This hybridization thing can only be put aside for the time being.

Fertilization or something, is it a relatively simple and easy thing to do, or do simple things first.

Lu Chensheng didn't say anything specific about the experiment, and Du Rufang didn't continue to ask when he saw this.

As Lu Chensheng continued to watch the valley.

The valley has not yet been completely rebuilt, but Du Rufang has seen how brilliant it will be once it is completed.

He had seen countless merchants come here before, and the merchants naturally brought abundant money.

And as long as the construction is completed, it will naturally become more and more lively.

Moreover, with the opportunity to make a living, it will also attract more and more people to come here, and at that time, even if Lu Chensheng does not publicize it, someone will take the initiative to come.

"Although the town here has not yet been completely built, you can already feel how prosperous it will be."

Du Rufang said with some envy, it was the first time he had seen a place that could give him such a feeling.

"If Brother Du likes it, you can stay for a while and see if this place will give Brother Du some different feelings."

Lu Chensheng opened his mouth to speak, he still hoped that the other party would stay.

When the other party discovers something different here, he may have something to do with Lu Chensheng.

Some of Du Rufang's talents also made Lu Chensheng quite excited.

"It's not okay to stay longer, I still have to go back to Dacangguo."

Du Rufang shook his head, and after responding, he continued to walk to the side with Lu Chensheng.

In the distance, dozens of children are arguing.

Listening closely, it wasn't an argument, but one of the kids was reprimanding the rest of the students.

"How many times have I told you, the volume formula of the displacement has been memorized, and then substituted it into the calculation, why can't it!"

The leading child was screaming loudly, his face full of anger, probably because he had been teaching them all the time, so he had some air.

At a young age, he actually has a somewhat gentleman-like posture, which makes people a little unbearable.

"And this, didn't I tell you about the topic of chickens and rabbits in the same cage? Column equations! How easy is this, I and the rest of my classmates heard Mr. say that they will be able to do it twice, but you still haven't learned it! ”

The student who took the lead was probably also mad.

led these people out, and during the event, I looked at the topic they had just written, and this look was basically wrong.

Therefore, it is impossible for him not to be angry.

"If you don't study hard, how can you help Mr. in the future? Steel can float like a ship, but you still want to build such a steel monster like this? I am afraid that you will not even see the day when you see it, and the descendants of the future generations will make it! ”

Some of the angry students spoke out loud again.

The children on the side listened, and kept shrinking their necks, their faces full of shock.

"What to do! Forgot what I said to you in class on the first day? Lift your chests and straighten me up! ”

Seeing the students bow their heads in shame, the students led by them became even angrier and scolded them again and again.

Du Rufang listened to the surprise on his face again and again, and he didn't know what was going on.

But listening to what this student said, it seemed to be extremely ostentatious.

Chickens and rabbits in the same cage, he has seen and solved this problem, but this kind of problem is for these children to do, are you sure they will solve it?

Also, what is the displacement? And ships made of steel? Won't it sink? How is it possible to float?

Du Rufang looked at this side in confusion, he didn't understand what these students were saying at the moment.

But after listening carefully to the child and continuing to say some words, he suddenly felt that there was some truth.

Let's just say that the chicken and rabbit are in the same cage, when the other party is explaining, it seems that the answer is reached in a few words, how is this done?
