Niu Si first floated up from the sea of blood, and when he saw that Zhong Yebai was gone, he immediately plunged down the sea of blood, swam along the string of intermittent bubbles, and scooped up Zhong Yebai, who had fallen into a semi-comatose state.

After pressing his chest a few times, Zhong Yebai spit out a few mouthfuls of blood from his mouth, and finally slowly woke up.

Zhong Yebai slowly opened his eyes, and the first thing that caught his eye was a fierce face, full of blood stains, and even blood dripping from his beard, which was really terrifying, even though Zhong Yebai was already very familiar with Niu Si, but he was still frightened by this terrifying face.

"Ahem!" After Zhong Yebai got up, he coughed up a lot of blood again, not his own, but the blood that had choked into his lungs in the blood lake just now.

"The world... Childe is alright, right?" Although no one else was present here, Niu Si forcibly held back after almost calling out His Royal Highness the Prince, and changed his name to Zhong Yebai Gongzi.

Zhong Yebai shook his head, signaling that he was fine, and then looked up to observe the environment of the space he was in.

This is a huge space, it is said that this is an underground cave, it is better to say that this is a huge building buried in the ground, its height is not said to be a thousand zhang, four or five hundred zhang is also more than enough, its diameter is three or four hundred zhang, the area of this blood lake, is the size of a standard football field, of course, the bottom of the entire space, most of them are covered by this blood lake.

There are countless holes in the huge dome, ranging from large to small. Each hole seemed to Zhong Yebai to be a small black dot, but Zhong Yebai knew that those small black dots were actually not small, and he slipped from one of those small black dots and fell into this lake of blood. In other words, those hollows seem to me to be a small black dot at this time, but in fact, each of them has a radius of one or two zhang.

It is also based on the judgment of the basic principle of near large and far small, Zhong Yebai estimated that the position he stood was at least four or five hundred zhang away from the height of the dome, which is a remarkable distance, you know, in the world before Zhong Yebai crossed, the world's tallest building, the King's Building, is more than a thousand meters, that is to say, the height of this space is half higher than the world's tallest building, which can be described as spectacular, so spectacular that Zhong Yebai almost suspects that this space is not a natural product at all.

Of course, this is not the only reason why Zhong Yebai suspects that this space is not a natural product.

There are countless things that resemble the root system of a tree, and the whiskers hang under the dome over and over again, and it is impossible to count how many, but it is more like the root system of the roots of the tree than the countless hoses hanging from it, except that the hoses have been covered with an unknown thickness of red sticky substance, as if they were blood clots attached to them.

But what made Zhong Yebai suspect that this space was not a natural product but an artificially created space was that not far from him, he actually found a staircase, although the staircase had been covered with a thick layer of substances that resembled blood clots, but the shape of the staircase resembled the stainless steel staircase in a heavy industrial plant, which really made Zhong Yebai wonder if he had crossed again in the process of falling, crossing back to the world he once was.

After crawling out of the blood lake, Zhong Yebai had adapted to the strong smell of blood here, no longer felt nauseous, and regained his strength a little, and walked towards the staircase that should not have appeared in this era.

"Smack!" Zhong Yebai walked to the stairs, used his palm as a rag, and pushed away the thick mud-like "blood clots" on the stairs, and the "blood clots" fell to the ground with a bang, like a puddle of mud.

Zhong Yebai gasped.

The staircase is really stainless steel......

Zhong Yebai looked at the stairs that Zhong Yebai didn't hurry up with, and couldn't help but gasp, "It's terrifying, it's really terrifying......"

Niu Si on the side didn't know why, looking at the staircase that didn't seem to be strange, but it was a bit like a staircase made of silver, and he still didn't know why, and wiped the staircase clean with his sleeve again, and still couldn't see what the clues were about the staircase that seemed to be made of silver, and it could actually make His Royal Highness, who had never been surprised, amazed, and then stunned.

"Childe, what's so terrifying?" Niu Si really doesn't understand, isn't this just a staircase made of silver? It is said that the palace of the king of Northern Qi back then also made a staircase made of gold! What's more, it is said that the demons in the extreme north built a golden palace, and the entire palace is made of gold, but that is just a legend, no one has ever seen it, the palace of the demon clan, how can everyone dare to see it with their own eyes? But a silver staircase can amaze His Royal Highness, who is accustomed to seeing glory and wealth, could it be that His Royal Highness really has amnesia?

Of course, Niu Si didn't know what Zhong Yebai was sighing about, because he didn't know that there was a material called stainless steel, let alone a font called simplified Chinese, and what Niu Si didn't know was that at this moment, the worldview of His Royal Highness the Prince in front of him began to collapse!

Zhong Yebai silently stared at the staircase in front of him that had been rubbed by himself and polished by Niu Si, and after repeated confirmation, there was no doubt that the material was stainless steel!

Could it be that the world has already invented stainless steel?

You must know that the invention and use of stainless steel this material was during the First World War, and later because this material is difficult to be oxidized, it is widely used in all aspects of production and life.

After Zhong Yebai crossed into this world, before seeing this stainless steel staircase, Zhong Yebai once thought that this was a period in the history of Chinese civilization that was not recorded by history, and it was a blank in historical records, but when Zhong Yebai saw this stainless steel staircase with his own eyes, Zhong Yebai's worldview began to collapse.

Of course, the use of stainless steel materials alone, can not make Zhong Yebai's world view begin to collapse, although stainless steel is a material invented during the First World War, but it does not prove that this era can not have, for example, there are many super-era technology applications in the history of Chinese civilization.

For example, in the Spring and Autumn Period, the Yue King Goujian sword used vulcanization technology, which has gone through more than 3,000 years and is still extremely sharp, and the invention of this technology was considered to be a technology invented before World War II in the academic community.

For example, in the burial pit of the Mausoleum of Qin Shi Huang, several bronze swords have been unearthed, when unearthed, this sword has been bent by hundreds of pounds of terracotta figurines, but when the archaeologists removed the terracotta figurines, the thin and narrow bronze sword was instantly straightened and restored to its original appearance, which is the memory metal technology invented after more than 2,000 years of experiments by countless scientists.

Therefore, seeing stainless steel here does not make Zhong Yebai's worldview begin to collapse.

What really made Zhong Yebai's worldview begin to collapse was the six simplified Chinese characters engraved in the center of the stainless steel steps - "Kuafu Biological Group".
