Xu Yuan smashed his mouth, reminiscing about the brilliant taste of the colorful kiwifruit.

He looked at the tree-lined camouflage illusion in front of him.

I vowed in my heart that I would make the strange and colorful fruit trees here ripen faster.

In this way, he can taste more exotic

fruits, but to speed up the ripening of exotic fruits, then a lot of chemical fertilizers are needed.

"Chemical fertilizer ......"

Xu Yuan thought for a while, and suddenly a plan came to his heart.

He called in a five-star farmer who was working.

This five-star farmer didn't know what to do when he saw Xu Yuan calling him.

Immediately, he rubbed his palms excitedly

and asked Xu Yuan, "Wang, I don't know what you are doing?" Xu Yuan asked straight to the point: "Where do you usually put the straw and wheat stalks and corn stalks after harvesting?"

"Of course, you set a fire and then buried it in the yellow earth!"

The five-star farmer asked with confidence: "Wang, am I doing the right thing? In this way, there will be a large amount of plant ash." And a large amount of grass and wood ash will gradually turn the yellow earth into fertile red earth! Now, our red earth is very oily

!" "It was actually researched by you, red earth? This credit should be recorded in the city hall!" Xu Yuan nodded appreciatively and said.

Hearing this, the five-star farmer laughed a little, and the two rows of white teeth reflected bright light in the sunlight.

But soon, Xu Yuan shook his head again and said, "It's a pity, you did something wrong!"

The smile on the five-star farmer's face immediately retracted.

I saw that he scratched his head a little weakly, and asked Xu Yuan humbly: "Wang, I don't know what is wrong, and I ask Wang to make it clear!" Xu Yuan

said: "This is very polluting to the environment! Although it is good for the land, it is not good for the atmosphere." During the burning of straw and wheat straw, a large amount of smoke is released. Although the land is very important to us, it is our mother earth, but the atmosphere is also very important, this is our father, isn't it?"

"Yes, yes, what the king said is very true!" The five-star farmer suddenly realized.

It turns out that they have been doing the wrong thing all along.

Fortunately, Xu Yuan corrected it in time.

Otherwise, they will kill themselves without knowing it.

Maybe not in the short term.

But in the long run, it will definitely have a big impact on the environment, and maybe for future generations.

"What should we do, then King?" asked the five-star farmer after a moment's thought.

Although he also wanted to come up with a better way.

But with his wisdom, he can only study things.

But they couldn't create anything at all.

That's at least something that can only be done by townspeople above six stars.

Seeing this, Xu Yuan announced: "It's simple, pass on my message." Then you will dig a great pit in the shade of the valley.

"Then the pit can be filled with human and livestock excrement, food scraps, unwanted wheat stalks and straw. Then close the lid and seal it up.

"Leave a feed opening so that you can dispose of the waste later. Then leave a vent and set a switch, so that the fertilizer inside can be fermented to produce a large amount of biogas.

"This biogas can be sent to thousands of households.

"In this way, we don't need coal to live and cook, we can turn on the biogas directly and light the stove, we can use as much as we want, and whether it is the speed of heating or the durability of combustion, and the cleanliness after combustion, of course, biogas

is more convenient!" "The most important thing is that this can be used to save coal, after all, although we have a coal mine, we can't sit on a mountain and eat empty, we need to save more fuel to support the steel mill to make steel!"

After Xu Yuan finished saying this, he immediately made your five-star farmer feel extremely admired.

Although this is only an initial idea, if no one puts forward this idea, they will not be able to imagine that such a thing still exists in this world!

After having the initial idea, the hundreds of workers in the town can design the technology that conforms to his concept step by step according to Xu Yuan's idea.

In this way, they will have one more convenient and useful thing in their town!

and they will have a place to dispose of the large amount of animal waste and plant carcasses.

The biggest advantage of this is that they can realize waste utilization, save energy on the basis of not polluting the surrounding environment, and then enter the era of sustainable development!

The five-star townspeople submitted this draft to the Baigong Research Institute according to Xu Yuan's instructions.

The people of the Baigong Research Institute suddenly opened their minds and began to develop Xu Yuan's initial idea.

At this time, Xu Yuan also felt that the amount of knowledge that originally had 200,000 left, but now it began to decrease sharply.

However, Xu Yuan was not distressed.

Anyway, this amount of knowledge is stored here and is only left idle.

And now, a lot of useless knowledge has a place to go.

After the Baigong Research Institute researched the plan for the construction of the biogas digester, then their stone town not only had a biogas digester.

It will also produce fertilizer to further accelerate

food production in Stone Town, even though it has already reached an astonishing level of food production in Stone Town.

But Xu Yuan still felt that it was not enough.

Because the future is uncertain, we don't know what will happen.

Judging from the tide of evil spirits that will come in three days, it is estimated that there will be an earth-shattering battle!

So, before the catastrophe strikes.

Xu Yuan must be prepared to face disaster.

Only in this way can we be fearless in the face of danger.

Soon.

Xu Yuan came to the city hall.

He's going to start issuing a decree for the new king to take the second fire!

he's going to do it as soon as possible before the tide of evil spirits comes.

Burn these three fires!

......

......

City Hall

"Mentor!" Zhuge

Liang, Xu Zhu, Guo Jia, Sun Shangxiang and Diao Chan, who were dealing with a large number of office documents in the city hall, were all busy at the moment.

In the past few days, as the territory of Xu Guo has been expanding.

As a result, their workload is increasing day by day.

They were too busy to even have time to report to Xu Yuan.

Now that Xu Yuan came to find it, they thought that something was wrong at work.

So, the five of them stood side by side like children who had done something wrong, waiting to be heard.

Xu Yuan smiled and said, "You don't have to be so nervous, by the way, looking at the current situation, there seems to be a shortage of manpower in Stone Town, do you want me to help you?"

Xu Yuan looked at his system space.

There are indeed more than 100 military generals of all sizes in it!

Every time you draw one, you will be a rare management talent.

If there were more than a hundred more generals in the town hall.

I guess there won't be so many piled up documents in the town hall that make people feel numb!

" Seeing

this, the five people hurriedly requested.

Cold sweat broke out on their foreheads, wishing that Xu Yuan could quickly recruit more people.

In this way, their workload is also reduced.

Seeing this, Xu Yuan nodded.

It seems that there is a real shortage of people in Stone Town.

Even if he had made another 10,000 celestials before, it seemed that it was still not enough.

I have to think of a way to increase the number of celestials, so that we can't stop the speed of Xu Yuan's infrastructure construction!

Xu Yuan sacrificed more than 100 military generals at once.

[You have drawn 176 Commander Cards!]

[Successful drawing, you have obtained 1-Star General*76, 2-Star General*80, 3-Star General*15, 4-Star General*5!].
