Chapter 520

LAN Xiangyu placed the five pieces of paper separately. The five pieces of paper had the same symbols and graphics.

"This should be the same element in the new material found in the soil all over the ancient earth? What is it?" not knowing these symbols doesn't mean she doesn't have a brain?!

What is recorded on these papers is the new material found on the ancient earth. Below is the composition. According to some written descriptions and common sense, we can basically infer.

Nanbu glanced and found that Lan Xiangyu had really found it.

"We brought back all the samples of new substances, studied and tested them with instruments, and then analyzed the components. It was found that these new substances contained unknown elements that had not been found in the Federation, and there was more than one.

However, there is only one unknown element that is common to five new substances. That is the element you pointed out.

We call it the "swab" element. "

"Are there no other planets with this element?" Lan Yueyu's voice was a little excited and his body leaned forward.

"Nature, how else is it called a new element... This element has existed on the ancient earth for about a thousand years.

However, I checked the data and found that the earth, the predecessor of the ancient earth 100000 years ago, seemed to have an element with similar structure and function, but later this element disappeared. "

"A thousand years..."

LAN Xiangyu began to think about the Lord's records he had seen.

From 1000 years ago to now, with the rapid development of federal science and technology, ancient Earth Science and technology has become more and more backward.

The land detector has not been updated in a thousand years, nor can it detect new elements. Naturally, it was not reported to the relevant departments of the federal government.

"Draw elements... Is this element easy to extract from the land?"

"The extraction rate is 80% to 83%. It is an easy to extract element."

"Are there any extracted elements? Can you give me some?"

"What are you doing?"

"Do a little experiment."

……

LAN Xiangyu dug a basin of soil directly in the courtyard of the scientific research institute. After detecting the composition and determining that it did not contain absorbing elements and that the constituent elements were the same, he divided the soil into two equal parts.

One part of the soil was added with nambuki's extracted element drawing solution, that is, a mixture of sterile water and element drawing. The same amount of sterile water was added to the other.

Put the soil into the incubator.

Then sow the same seeds in two parts of soil. Take out the planting robot of the ancient earth from its own terminal and clap your hands after setting the watering interval.

"Wait, wait for two planets."

LAN Xiangyu was also a little helpless. After two planets, it was a month since the start of the hiding mission. But what can be done?

She dared not use ripening agent and nutrient solution to speed up seed germination, so she had to wait.

Waiting is long.

But because all the seeds are rotten, LAN Xiangyu wants to discuss with the major planets and then renegotiate. She is also very busy. After these things, two weeks will be busy.

LAN Xiyu came to the laboratory again. Before entering, LAN Xiyu saw small green seedlings emerging from one group of soil. LAN Yueyu rubbed his eyes for fear that he was wrong.

He carefully walked forward a few steps, and his face was pasted on the glass of the experimental box.

Small tender green seedlings, vibrant fresh green. Although only a few centimeters of his head popped out of the soil, it was these centimeters that made LAN Yueyu excited to tears, happy to dance!

Talking with Meng Jiao caused Shen panchi to arrive late. As soon as he entered the laboratory, he saw LAN Xiyu turning around in situ, with a silly smile on his face.

LAN Xiangyu saw Shen panchi and ran to him with his mouth open and several big white teeth smiling at him.

Shen panchi smiled, "little Han Han."

The smile is so cute, so cute that it bubbles. Han Han.

"That sprouted?"

"Mm-hmm!" Lan Xiyu pulled Shen panchi close to the experimental box. "You see, the food seeds with absorbing elements germinated. The ones without absorbing elements didn't germinate. I guess it should be rotten."

LAN Xiangyu took a picture first, then took out the two parts of the soil and planed the soil without absorbing elements with a small shovel. Sure enough, with a very light rotten smell, rotten food seeds came out.

The other side is planed out and has roots. It's normal.

LAN Xiangyu took another picture to deal with these things.

"It seems that it is the reason for absorbing elements. The soil of food seeds needs elements to mature normally. Except for the ancient earth, there is no element in the soil of planets. Therefore, food seeds cannot survive."

LAN Xiangyu said that normal soil planting needs to absorb elements, but if some special culture medium is used to replicate food materials, it does not need to absorb elements. However, this is not consistent with the content of the hidden task. And it's not realistic to copy a lot of ingredients.

Now LAN Xiangyu is much more relaxed. He knows that the survival of food seeds needs to absorb elements, and the elements are real. All you need to do is add elements to the experimental fields on various planets!

"I now understand why these delicious foods will slowly disappear in 100000 years.

In addition to the invention of nutrient solution due to the need for unified and simple food with the development of science and technology and the addition of interstellar races.

Another reason should be that other planets do not contain the elements required for the growth and development of crops brought to the stars by the earth people 100000 years ago, so they are gradually extinct. "

This is only LAN Xiyu's guess. After all, there are differences between the seeds of the earth's crops and systems.

"Well, now that we have found the root of the problem, the next step is to solve the problem. So where are you going to get a lot of pumped elements? At present, only pumped elements have been found on the ancient earth in the whole Federation."

"That's the ancient earth..." Lan Xiangyu blurted out, and his expression solidified.

The element has existed in the soil of the ancient earth for thousands of years and has formed a stable ecosystem. If the element is extracted, the ecological balance of the ancient earth will be destroyed.

Although it takes only 9000 mu of land to complete the hiding task, it is not much. However, if the elements extracted from the 9000 Mu soil disappear, no one is sure whether it will cause a chain reaction such as the deterioration of the surrounding soil.

LAN Xiangyu thought for a long time, then slowly said that he thought of a way in his heart,

"First find it within the Federation. If you can't find it within four months, select 9000 mu of land from the remote desert of the ancient earth."
