Lan Siyu watched this orderly scene from the high-rise building next to the industrial park and felt very gratified.

Sure enough, science and technology are the primary productive forces, and the ancients did not deceive her.

"The streamer is really great! The ancient earth is really much better now than it used to be. Wenzhou Mountain looked at Lan Ruyu with little stars in his eyes.

Lan Qiyu, who was angry in Nanbei, instantly felt a lot more relaxed, "Alas, where, where." That's it, and we have to develop well! ”

"Oh no, it's already great! It's only been a year, and it's still in the remote and backward ancient earth with very few people! Excellent! "The sycophants of Wenzhou Mountain are here again.

"Say, what do you want to eat at noon today, I will satisfy you!" Lan Ruyu waved her hand, quite a bit of the momentum she had in the world.

"Hehe, I really think that the anchor is very powerful, not to eat the food cooked by the anchor! The anchor is very good, very good, and very responsible, by the way, I want to eat braised pork and stir-fried red. ”

Because the red color contains violent factors, the treatment steps are more troublesome than others, and it is necessary to use purified water to nourish the society first, so Lan Ruyu generally does not use red as an ingredient when cooking for Wen Chi Wen Qilian.

The main thing is to deal with trouble, and she is lazy.

"Well, I haven't eaten in a long time."

As the two spoke, they saw Nan Bei and other people from the scientific research institute walking below.

They didn't enter the industrial park, they just stood there and watched the fruits and vegetables that everyone carried, and some researchers even ran to see the process of grinding flour with machines.

Mills are common, but grinding flour is uncommon.

Lan felt like she had pulled back another game.

Seeing that a few people didn't behave out of the ordinary, Lan Qiyu didn't bother to look at it. After all, they came to the ancient earth to test the environment, so it doesn't matter if they come to see it.

Lan Ruyu took Wenzhou Mountain to a small river ditch inside the industrial park, which used to be used for everyone to irrigate, but now that the industrial park has a unified irrigation system, the small river ditch is useless.

Before you even walked in, you could see a patch of red and yellow.

Insect beasts are different from the Zerg, the Zerg belong to the Zerg, but not all insects and beasts are Zerg, such as Crimson, which is planned to be classified as an insect beast because it simply contains a violent factor. If it does not contain the Violence Factor, then Crimson will probably be classified as an alien beast.

It is precisely because Crimson is not a Zerg and does not have those twists and turns of the Zerg that Lan Ruyu dared to continue to eat Crimson after learning about the strange way of reproduction and survival of the Zerg, an interstellar race, and did not reject Crimson.

If Crimson also reproduced in the same way as the Zerg, Lan Qiyu felt that she might have a shadow on Crimson for the rest of her life.

In the afternoon, Lan asked Lanx to bring researchers from Nanbehe Research Institute to visit the industrial park.

Some of the crops in the industrial park have been harvested in the morning, and some have not, but despite this, it is enough for a few people to visit for an afternoon.

Lan and Wenzhou discuss his investment projects in the office.

Wenzhoushan and his classmates have developed a new yellow sand flying jet. According to the introduction of Wenzhou Mountain, it is based on the yellow sand mixture to turn the yellow sand into the soil, and the improvement processing is carried out.

The new version of the Yellow Sand Flying Jet Solution is more functional and efficient than the Yellow Sand Mixture. It can turn yellow sand into soil in a short period of time and using a small amount.

For example, to turn one acre of yellow sand into land, one standard barrel capacity of yellow sand mixture is required, but if the yellow sand flying sprayer solution is used, only one-third to one-half of the same container is needed to turn one acre of yellow sand into soil.

For a large desert area such as the ancient earth, the efficiency of the flying jet is much higher than that of the yellow sand mixture, and it is also more convenient.

"Is it mass-produced?"

"No, now it's only tens of thousands of acres." Wenzhou Mountain scratched his head and laughed embarrassedly

"Isn't it still in the experimental research and development stage, hehe. We searched for seven planetary deserts and did seven experiments, and the planets were different, the geology was different, and the results were all different.

I brought the yellow sand flying jet over this time, mainly to try what kind of effect it will produce in the desert of the ancient earth, if the effect is good, we can contact the factory for mass production. ”

"Okay, when are you going to try it?"

"Just wait, finish the experiment as soon as possible, and let it be produced over there as soon as possible."

The two left and went to the desert outside the oasis where soil had not yet been soiled to conduct experiments.

I saw Wenzhou Mountain take out a circular aircraft with a diameter of about two meters from the terminal. After adjusting the spraying concentration on the surface of the aircraft, the red button was clicked, and the aircraft flew up, and within half a minute, it began to spray black liquid.

"This flying machine is expensive, isn't it?" Thousands of flying jets work together, and the efficiency is increased by many times, as long as the solution is sufficient, all the deserts of the ancient earth can be turned into land in less than a few months.

Lan Ruyu said that she was tempted.

"It's okay, the capacity of this kind of loading flying jet is not very large, generally more than 50 million." Wenzhou Shan said indifferently.

Lan Yiyu: More than 50 million... Five thousand times one thousand equals...

Forget it, let's take it slowly, in fact, she's not in a hurry...

As they spoke, the desert in front of them had turned into black soil.

Wenzhou Mountain took out the instrument to test the depth and soil quality of the soil, and looked at the measured data, "The soil quality changed by the ancient earth ranks third among several planets, and the conversion efficiency is 93 percent, which is in the second place." But ......"

"What's wrong?"

"The nutrients contained in the soil of each planet are not exactly the same, but they are roughly the same. However, in addition to the nutrients recorded in the measuring instrument, there is also an unknown element among the nutrients in the soil of the ancient earth that have just been measured..."

Wenzhou Mountain felt very strange, with the 100,000-year investigation history of the Federation, two unknown elements were discovered in the ancient earth within a year.

"What? Unknown elements again?! Lan Ruyu looked at the symbols on the display screen closely, okay, most of them she still couldn't understand.

"Look, that's it."

"Strange, is it a problem with your solution?"

"How is it possible, the planets we experimented on before have not appeared in this situation."

The two of them left again, ran into the desert, and continued to measure.

"You see, there is still this unknown element, which is the cause of the ancient earth."

“……”

"Let the people from the research institute do the research... They love to study the unknown. ”

Lan Ruyu suddenly felt that the ancient earth was full of mystery, the history of the Federation was 100,000 years, and all the elements found on the earth had already been recorded. If the unknown factor in the ingredients is better to say, after all, it is something in the system mall, and the system is the product of another parallel universe.

But the unknown elements in the soil of this ancient earth, Lan Ruyu didn't know how to explain it, could it be that it was produced in the past 100,000 years???
