Li Yu has been standing and looking at this area that looks empty for a long time. Xiao Wei thinks that Li Yu has already discovered something when he comes here for entertainment.

In fact, Li Yu could confirm whether there was anything with just stretching out his hand, but he was persistent in observing with his eyes.

There is only one thing in this area. Li Yu looked at it carefully for a long time and came to a conclusion. He believed that it was a crystal coffin, a coffin composed of some kind of crystal.

Since the refractive index of this crystal is almost the same as that of water, if it is not in front of you and you will ignore it if you look at it deliberately.

Li Yu discovered anomalies when using his mana to detect the basement. The refractive index of the crystal is the same as that of water, but its reaction to mana is a bit different from that of water. It can be said that mana and everything are different, and there are only differences between big and small.

"It's so strange, Li Yu, our detection system should easily separate it from water, but the detection results show that there is nothing in this basement except water and stone."

Li Yu did not answer Xiao Wei's question, because so far, he did not know the answer to this question. Only after detailed research can the exact results be obtained.

As soon as she saw Li Yu's expression, Xiao Wei knew that Li Yu had no idea now, so she stopped asking.

In the basement, due to the existence of water, it would be very inconvenient to study the crystal coffin, so Li Yu decided to transfer the crystal coffin to the square in the center of the castle for research.

Xiao Wei has commanded the robot to form a temporary laboratory in the square in the center of the castle.

With Xiao Wei's help, Li Yu brought this strange crystal coffin out of the basement.

When we arrived at the square in the middle of the castle, the robot had already built the temporary laboratory, so the crystal coffin was moved to the temporary laboratory.

Li Yu made new discoveries, and Xiaowei shared the news with other people in the laboratory as soon as possible.

After learning that Li Yu had made a major discovery, Fang Qianmo and the others put down the things they had at hand and rushed to Xiao Wei's coordinates.

Before Li Yu's laboratory started, Fang Qianmo and the others came to the castle.

Then, ignoring Li Yu, Fang Qianmo and the others who were adjusting the equipment, they began to savor their heads and discuss their strengths around the crystal coffin.

"What is the purpose of this crystal coffin? It's not really used as a coffin, right? Will that civilized taste be a bit strange?"

Lin Wanbai first asked a lot of questions.

This kind of crystal coffin should be used as a work of art for people to admire. This is what Sun Yixuan thinks. If someone uses it as a coffin, she thinks it is the biggest crime.

"It should not be possible."

This crystal coffin is three meters long, one meter high, and one meter wide. It looks like it is formed in one piece, very much like a piece of crystal, polished into the shape of a coffin.

Therefore, Fang Qianmo did not think that this crystal coffin was used as a coffin.

"You're thinking too much. Although it looks like a coffin we've seen, no one stipulates that all coffins in the entire universe are used by the earth, right?"

"Maybe, according to the customs of a certain civilization, this crystal coffin is just a luxurious bed for others. They just use this crystal coffin to sleep at night!"

Lin Wanbai refuted Sun Yixuan's worries from another perspective, but this angle is really speechless.

But this may be true. The universe is full of wonders. It is also extremely normal for other civilizations to have very strange customs for the people on earth.

Maggie did not express her opinion. She used her mana to detect the inside of the crystal coffin, and then said in surprise: "The interior of this crystal coffin is a liquid, and the thickness of the crystal coffin is very standard ten centimeters."

After hearing Maggie's words, Fang Qianmo and the others also used their magic power to detect the inside of the crystal coffin and found that it was indeed as Maggie said, all of which were unknown liquids.

"Li Yu, you've discovered it long ago?"

Fang Qianmo turned around and asked Li Yu who was busy.

"Yes, it was through mana detection that I discovered this crystal coffin."

Xiao Wei took Li Yu's words: "Then he stood stupidly in front of this crystal coffin for half an hour, not knowing what he was doing!"

Regarding Xiaowei's comment, Li Yu just said, "Haha!"

Li Yu's unique hobbies, whether it is Fang Qianmo or Lin Wanbai, will not express any opinions.

As a scientist, Li Yu discovered a new thing, and when he had no research instruments at hand, he used mana to detect it, which was also the most basic quality.

It's just a bit strange to stand there just to look at it.

No matter why Li Yu had a strange behavior, Fang Qianmo was fascinated by the beautiful appearance of the crystal coffin when he saw it. He subconsciously forgot about it and used his magic power to detect this step.

Mana detection, this technique should be one of the most practical spells developed by Li Yu.

To be honest, Fang Qianmo and the others have not encountered such spells as Li Yu. Even Green and the Roland civilization, if it were not for Li Yu's help, they would not have such spells.

It’s not that people with a wizard civilization do not have similar methods to detect magic powers, but their similar application directions are not like Li Yu.

The magic power detection of the mage civilization is more of a macro detection method, but Li Yu has already penetrated into the microscopic world with the tentacles of magic power detection.

Through the action of mana and atomic particles, the results feedback from mana detection can be analyzed by Li Yu and the others, thereby obtaining detailed information about the target, such as the composition of matter elements.

Because magic power is just an energy after all.

After all, it is a difference in thinking, which leads to such a result.

Li Yu's experimental equipment was finally debugged, and then he came to the crystal coffin and stood with Fang Qianmo and the others.

"How about it, have you detected the liquid in the crystal coffin?

"There is one thing that the liquid in the crystal coffin is rich in life energy."

"And this kind of crystal can actually isolate the effect of life energy, so we did not detect life energy. I found that the concentration of life energy in the liquid is also far higher than that of the outside world."

Fang Qianmo discovered the secret of the crystal coffin. The material of the crystal coffin can isolate life energy. In a sense, the crystal coffin is just a container.

Well, the crystal that isolates life energy is actually just one-way isolation. The life energy from the outside can enter the inside of the crystal coffin.

However, this crystal material has an isolation limit. If it exceeds a certain concentration of life energy, it cannot be perfectly isolated and will cause leakage.

Fang Qianmo also discovered the secret of the crystal material of the crystal coffin.

"So, this crystal coffin is a container for preserving life energy!"

"You can't be so sure, right? Maybe it's possible that they just use it to take a bath!"

Lin Wanbai proposed the function of the crystal coffin from another perspective.

However, her thoughts and everyone's reaction was, "Haha!"

"However, Wanbai said nothing wrong. The container for preserving life energy is just our guess, and it is not necessarily correct."

Li Yu believes that Lin Wanbai's words are correct to some extent.

Hundreds of thousands of years ago, the life energy of this planet was still extremely rich, so it would be a bit unworthy to study this method of preserving life energy.

"Life energy is not available on every life planet. As an interstellar civilization, if there is such a need on other planets, wouldn't it be necessary to develop the technology to preserve life energy?"

Maggie believes that Fang Qianmo’s view should be correct.

"That's right, it's not true. After all, not that civilization can obtain life energy at will just like the laboratory."

After hearing Maggie's words, Li Yu realized that not any civilization can use life energy at will, just like a laboratory.

As long as the guess is, let’s see if the results of the experimental test are consistent with the guess.

The first thing Li Yu had to do was to analyze the material of the crystal, study its structure and composition form, and figure out why it can preserve liquids with rich life energy.

The second step is to analyze the liquid composition inside the crystal coffin and figure out why its life energy is so abundant.

Li Yu was about to start research, but the others did not intervene. So Fang Qianmo asked a question.

"Li Yu, when did the life energy on this planet become so thin?"

"The test results are there, you can see it yourself."

Li Yu controlled the high-frequency oscillation knife and carefully cut the sample from the crystal coffin. After listening to Fang Qianmo's question, he answered without hesitation.

Fang Qianmo opened the terminal and found Li Yu's analysis results on the life energy of this planet.

The concentration of life energy on this planet began to drop sharply about a million years ago, and then after it dropped to an extremely low level about a hundred thousand years ago, the rate of concentration decline began to slow down.

Seeing Li Yu's research results, Fang Qianmo immediately had a guess in his heart.

When the concentration changes of life energy and concentration on this planet are abnormal, it is the time when the builders of these buildings discovered that there is life energy on this planet, and then they developed the planet.

After the life energy was consumed so much that it could no longer be used, the builders gave up on the planet.

This conjecture cannot be explained.

As long as the life energy does not disappear completely, it will always be used.

Giving up this planet without completely utilizing the life energy on this life planet? This is a bit impossible.
