Under the gentle fluorescence of the night pearl, you can see that the inner wall of the "crystal coffin" is a smooth arc shape, just in size that can lie into an adult.

The inner coffin is milky white and as neat as new. On the inner wall of the coffin, there seem to be some tiny holes and gaps as thick as hair. If you don’t look carefully, you can’t see it. I don’t know if it is used for breathability or what to do.

"Touch with your hands." Su Rui reminded Zi Yang.

Zi Yang reached out and touched the inner wall of the coffin with his hand, and looked at Su Rui in surprise.

"This is ceramic?"

Su Rui nodded.

Zi Yang took a breath and said, "Although I have heard of ceramic coffins before, they are very rare. Such a large and complete ceramic coffin seems to be recorded in history."

Su Rui nodded: "Yes, it is very difficult to fire large ceramics and are prone to cracking or leaving flaws. However, regardless of other aspects, just from the perspective of physical properties, a coffin made of ceramics should be the best tool for preserving corpses."

Zi Yang said: "I remember seeing from books before that ceramics are the most stable things on the earth. If one day the civilization on the earth is destroyed, all symbols of human civilization - metal, architecture, books, wood, plastic, etc.... will slowly decompose, corrode, weather until they disappear over the long years. Only ceramics will be preserved intact and become the last relic of civilization."

Su Rui nodded: "In theory, that's the case."

Zi Yang looked at the crystal cover next to him and hesitated: "Is this one in front of us a crystal ceramic coffin?"

Su Rui gently stroked the coffin with his finger, "I can't confirm that it's suitable to make small urns of ceramics, but it's unheard of to make such a large coffin. The key is that the crystal ceramic coffin in front of us is so exquisite, and the details are simply as good as the realm of perfection. Can ancient humans master such technology?"

Zi Yang pondered: "Porcelain and porcelain have a long cultural history in China, and some of the techniques mastered by our ancestors seem incredible even today. Among the Qin Dynasty ruins discovered more than two thousand years ago in Xi'an, there is a sewer made of intact pottery. The craftsmanship of the production of the transfer interface is out of date today.

There is also crystal craftsmanship. A crystal flavour cup was unearthed in a mound tomb during the Warring States Period. The fineness of the production makes people unable to believe that it was an ancient product.”

Su Rui nodded, "I have read the information about what you said, but it's so small compared to what we have in front of us. Look at the quality and size of the ceramic inner coffin and crystal coffin lid, it's so perfect."

Su Rui walked around the other side of the crystal coffin and said, "Come on, let's lift it up."

The two of them gently lifted the crystal cover and slowly closed it on the ceramic coffin. The edge of the crystal coffin lid perfectly fits the ceramic coffin body.

"Look, it's a tight fit - I even suspect that a sealed vacuum can form inside - it doesn't look like a work that ancient humans could create."

Zi Yang uncovered the crystal coffin lid again - the place connected to the coffin body seemed to have used some exquisite simultaneous technique. The heavy crystal coffin lid was not arbitrary at all and had almost no friction resistance.

Zi Yang stretched out his hand and slid across the smooth glaze surface of the ceramic. He felt that the tentacles were extremely smooth and there were no flaws. He not only sighed at his exquisite craftsmanship in his heart.

Su Rui sighed: "Although this crystal ceramic coffin cannot be seen in its age, the layer of soil knots covered with the outer layer must be even older than the tomb of the Mongolian general above. There are also the fine slits and holes on it. I really can't figure out how to make it. Even modern craftsmanship may not be able to achieve such a level."

Zi Yang said: "It's strange, how come it is, according to what is the origin of this thing?"

Su Rui said: "From the quality of this ceramic, I judge that this is not ordinary ceramic, but space ceramics - I once interned in an aerospace unit in Europe and saw similar products."

Zi Yang wondered: "Ceramics can still be used on spacecraft?"

Su Rui nodded: "Space ceramics are highly resistant to high temperature, corrosion, good insulation, and radiation-proof properties. They are also an important material in aerospace technology."

Zi Yang asked in confusion: "What do you mean is this thing a modern technology product? So who put it in? How is the question?"

Su Rui stood up and took a deep breath, "Even with the current craftsmanship of human beings, such a product may not be able to be made. I suspect that this is a super civilized device that surpasses human technology."

Zi Yang opened his mouth wide in surprise: "What do you mean? Is this a prehistoric relic of an alien civilization?"

At this time, Qingwen and Achong also walked over from the thick fog. They had already explored the edge of the entire platform, heard the two of them discussing, and walked over together.

Looking at the "ceramic crystal coffin" in front of them, the two were also surprised.

Zi Yang asked them how they were patrolling, and A Chong said in a deep voice: "We have all thought wrong before. This platform was not built manually, but is actually a natural small crater."

Zi Yang was stunned: "Crafts? Do you mean it is like those craters on the moon?"

A Chong nodded.

Although the visibility is very low, I can't see things a few meters away clearly, Zi Yang still looked around habitually and said in surprise: "Is this a crater hit by falling objects from high altitude?"

Everyone looked at the crystal ceramic coffin in front of them. If the center of the crater was the impact origin, then the only thing that hits downward is this "crystal ceramic coffin".

Judging from the current crater area, the impact force should be very large. Based on the volume of this crystal coffin, even if the physics knowledge is limited, Zi Yang can infer that in order to cause such an impact force, the crystal ceramic coffin is likely to fall from outer space.

But the entire cave is closed, so where did the coffin fly down? Could it be that it jumped out from the underground?

All these phenomena that violate physical common sense have confused everyone.

Su Rui also told A Chong about their discovery, and A Chong held the crystal coffin with one hand and fell into deep thought.

It is obvious that this "crystal ceramic coffin" does not come from the earth.

A Chong stroked the thick rock shell covered by the outer coffin and said, "Did the crystal ball that Yinzi stole from this crystal coffin?"

Zi Yang suddenly remembered the first group of people who came into contact with the crystal coffin, "I'll bring Liu Xiaoshuai here to ask."

...

Lao Wang sat cross-legged on the ground chatting with Liu Xiaoshuai. Seeing Zi Yang coming hurriedly from the thick fog, he frowned and said, "Old Li, what are you doing there? I just chatted with Xiaoshuai for a long time and found that this was also a hard child..."

Zi Yang had no time to chat with him, so he pulled Liu Xiaoshuai and left.

Liu Xiaoshuai was dragged to the crystal ceramic coffin by Zi Yang. Seeing everyone's serious expressions, he was so scared that he bowed to A Chong, Su Rui and others repeatedly, "Brother, sister, I know I'm wrong. I will never dare to do bad things again!"

Zi Yang gently patted his head on the back of his head: "What are you thinking? You are not going to execute you. Let's find out about the situation with you!"

Liu Xiaoshuai touched the back of his head and kept saying, "I, I have told you what I know..."

A Chong asked, "Did the crystal ball be taken out from under this stolen hole?"

Liu Xiaoshuai nodded.

Su Rui said gently: "Tell us about the complete process of opening the coffin."

Liu Xiaoshuai said with a frown: "My professional expertise is blasting and excavation. This specific coffin opening work is done by the confidant of the boss Yinzi, and it is not my turn at all - by the way, Boss Hao, Boss Hao has opened the coffin with Yinzi here."

Zi Yang said to Ah Chong: "I'll bring him here!"

A Chong nodded and added: "Take Lao Wang, Jin Guoqiang and others here too, don't be too dispersed."

Zi Yang nodded and turned around and disappeared into the thick fog.

After a while, Lao Wang carried Jin Guoqiang and Zi Yang came from the thick fog with Xiao Hei's body in his arms. Behind him, Boss Hao with his head hanging down, Xie Lao Er with his head shrank, and Mo Lao San with his Dzi bead stone like the goddess of liberty.

"Senior, you don't have to hold the Dzi bead stone all the time, it will also work if you put it on." Su Rui saw that Mo Lao San was really struggling to hold the Dzi bead stone so he couldn't help but persuade him.

Mo Lao San shook his head like a rattle: "That's different, that's different, one inch long and one inch stronger. If I raise the Dzi bead stone a little higher, then our safe distance will be a little larger. Although it is only one or two meters away, sometimes it is only one or two meters away to save everyone's life."

Seeing that he insisted, Su Rui was embarrassed to force him to persuade him, so Xiaoxiao ignored him.

"Hey, this is the crystal coffin?" Mo Laosan saw the treasure in front of him, and couldn't help but come up, stretched his neck and looked inside.

Seeing that he was still holding the Dzi bead stone high above his head, Zi Yang hurriedly greeted him: "Be careful, don't slip your hand and fall the Dzi bead stone and smash this 'baby'."

"How could it be? I'm not an impatient young man..." Mo Laosan said as he suddenly shaved the Dzi bead stone on the crystal coffin, and looked at Zi Yang with a shy face.

People in their fifties and sixties are still playing with this!

Zi Yang was also amused and laughed at him when he looked like an old naughty boy.

"Wait a minute! Don't move!" Su Rui suddenly shouted loudly, his voice very quickly, which scared Mo Laosan.
Chapter completed!
