Wu Liang immediately took out the small brush and carefully cleaned the area.

Soon after, he had removed the outer layer of patina nearby, and Wu Liang also dug out bit by bit the red soil and rotten roots that filled the gap.

At this moment, the small gap finally appeared in front of him.

The gap was about an inch long, about one centimeter wide, and about three centimeters deep. The cut was extremely smooth, and it looked like it might have been injured by some kind of relatively thin sharp object.

At the same time, Wu Liang also saw clearly the situation inside the gap.

There are actually three layers in the gap, which look like sandwich cookies.

The first layer is the outermost layer of patina wrapped around the bronze statue. This layer of patina is about half a centimeter thick.

Under this layer of patina is a layer of pure purple-red simple copper. This layer of simple copper is only about one centimeter thick.

Under this layer of elemental copper is a black substance.

This black substance is hard in texture and looks like some kind of rock. This should be what is inside the bronze statue.

But what is more amazing is that this kind of rock and elemental copper have already merged. To be precise, it should be that elemental copper has penetrated into this kind of rock, and the place where they intersect forms a mixture of me and you.

state, it is basically impossible to use physical means to separate the two.

"The simple copper is fused with the rock inside the bronze statue?"

Wu Liang concentrated on the process of making this bronze statue, "Could it be that the human figure was carved out of stone first, and then the molten copper was poured on the stone sculpture, and then the outer layer of the stone was plated like making chocolate ice cream?

Such a layer of copper?”

"But if it were a copper plating process, it would never be possible to plate such a thick layer..."

Wu Liang thought of the copper chainmail he was wearing that Wen Renzhao had given him. The copper chainmail used copper plating. In fact, its essence was fine iron, with a layer of purple-red.

Simple copper is just a thin layer of decoration, not even one millimeter thick.

For example, it is impossible to use the copper plating process for the one centimeter thick single copper on this bronze statue. The copper can only be made and inlaid bit by bit.

In this case, it is simply impossible for the metallic copper to fuse with the rocks inside.

In addition, environmental factors can also be eliminated. After all, apart from a layer of patina on the outside of this layer of simple copper, there is no other serious oxidation phenomenon. This means that the preservation environment of this bronze statue is still acceptable.

Extreme high or low temperatures can be basically ruled out.

"What is the black substance in this?"

Unable to figure out this problem for the time being, Wu Liang turned his attention to the black substance inside, and at the same time waved to everyone, "You guys, come over and see what the things inside are."

Everyone was also full of curiosity and had been waiting aside for a long time. When they heard Wu Liang's greeting, they quickly came over.

After going around like this.

"Gentleman, I don't know much about it, but I think the black stone here is quite similar to the stone on the Holy Mountain, but I don't know how to verify it."

Cao Ni, who never had the chance to participate, expressed his views to Wu Liang first.

This girl has lived a prosperous life since she was a child and has been the focus of people on many occasions. However, when she arrived in the Qian army, she had no advantage compared with this group of strangers who had their own specialties. Therefore, she always wanted to find opportunities to express herself.

In order to avoid being too insignificant in front of Wu Liang.

"Stones on the Holy Mountain?"

Wu Liang frowned slightly.

The holy mountain above should be made of strong magnetic basalt. Since this bronze statue is standing here, it is naturally more convenient to use local materials.

However, strongly magnetic basalt is a very distinctive rock. If it must be associated with copper...
