This underwater passage is not spacious, only less than 1.5 meters in width, which can only allow two people to walk side by side. Feelings of suffocation and oppression.In order to prevent any aggressive creatures inside, Hu Zhibo took the lead and sneaked inside to inspect the situation.Fortunately, there are no living things in the passage, only the slippery stone walls are covered with moss.

The team then filed in.Gu Fengchun walked at the front of the team this time, and he found that the passage here is slightly raised forward, presumably the terrain here is at the end, and there must be a place away from the water.There should be a place filled with air.

Thinking of this, Gu Fengchun breathed a sigh of relief.The oxygen on the masks on everyone's bodies has already been almost exhausted.Relying solely on the oxygen inside, I am afraid it will not last long.So he immediately let everyone speed up their progress.

"Feng Chun, look at this stone wall." Xiao Zhonghua accidentally rubbed off a thick piece of algae, and found that there is another universe under the algae cover.So he communicated his discovery to Gu Fengchun through the communicator.

Gu Fengchun quickly swam to Xiao Zhonghua's side.

What Xiao Zhonghua discovered was a mural.Some lines outline the pictures of some characters on the wall.But the displayed part is still very narrow.Gu Fengchun drew out the military thorn, and slowly scraped it against the wall.Seeing this, everyone also took out utensils to help scrape the wall. After a while, the moss on the walls on both sides was peeled off, revealing a magnificent picture.

The lines of the murals are very delicate, but also very simple.It's just a mural drawn with the simplest lines, but it doesn't matter that Gu Fengchun was shocked by it.

It's a narrative mural, and it's quite long.Everyone just scraped the moss on the section of the road they swam through, and the part that went inside was still hidden in the seaweed moss.Gu Fengchun signaled everyone not to stop, and continued to blow inward, while he himself swam back, wanting to look all the way from the entrance, and take a closer look.

Luo Xiaodan knew Gu Fengchun's intentions, but he was worried that he was alone, so he went with him.

There are murals on both sides of the walls.Fortunately, the murals on both sides describe different things.Moreover, Gu Fengchun feels that the ages of the two murals are not the same, and the time is very far apart.The mural on the left is obviously much rougher than the one on the right.

Inside the mural on the left is a huge mine where people are mining and smelting.Gu Fengchun was surprised to see some familiar tools from the pictures of these mines.Those are mining carts!In addition to mining vehicles, there are many mechanized equipment.It's just that the murals are relatively simple, and Gu Fengchun can't see what they are at all.Gu Fengchun trembled all over, unable to speak.How could such a thing appear in this mural?Gu Fengchun's mind was a little foggy.

But that's not the point. In the mural, apart from mining, there are also smelting factories and items that were smelted: copper pillars!Bronze pillar!Gu Fengchun had seen these bronze pillars before, and these bronze pillars stood at the entrance of the temple.Judging from these proportions, the actual length of the bronze pillars may not be less than 500 meters.The part I see is only a very small part exposed on the surface.

Gu Fengchun soon discovered that after the murals came to these bronze pillars, the picture became quite different.Because Gu Fengchun saw that these bronze pillars were transported by manpower and animal power!In an era when mining has already been mechanized for production, is it possible that manpower is used to transport finished products?Gu Fengchun shook his head, not knowing what was going on.But when he compared the murals before and after, he found that there was another mystery inside.Just compared the picture of human transportation with the previous picture, except for those bronze pillars that have not changed, everything else has changed.The factories and equipment behind the bronze pillar were all reduced to ruins.

Gu Fengchun seemed to understand something all of a sudden.The records in the murals are civilizations earlier than the emergence of human civilization.When Gu Fengchun communicated with the mysterious female voice in the Great Forbidden Land, he got a positive answer.Before the appearance of human beings, several high-level civilizations similar to human beings were destroyed by prehistoric humans.And the female voice also said that some civilizations are even more advanced than the current human civilization.

Gu Fengchun watched anxiously all the way, wanting to know what happened during this period.But to his disappointment, nothing of great value was found in these murals.However, he counted several different changes.These changes are: the background of the murals has been changed six times in total, and these pictures, from smelting copper pillars to transportation, to construction, to completion, are all transformations between the mechanical capabilities of a high-level civilization and the physical strength of a low-level civilization.

This shows what?Gu Fengchun's mind turned quickly, and he quickly came to a conclusion.That is this temple, which was successfully built after going through different civilizations and a very long time.During the construction of this temple, it experienced a total of three transformations between high civilization and three low civilizations before it was finally completed.

In Gu Fengchun's cognition, it was the Wu people who built this temple under the guidance of prehistoric humans!But this discovery is enough to prove that his previous cognition was wrong, maybe not completely correct.It is likely that the Wu people participated in the construction of this temple, but they only participated in part of the construction of the temple.But Gu Fengchun didn't know which part the Wu people participated in, was it the high-end period of civilization development, or the low tide?

There is one more thing Gu Fengchun doesn't understand.Why is this temple always being built during the replacement of these civilizations?Why didn't prehistoric humans allow one of the civilizations to build this temple and then kill it?

Gu Fengchun felt that his mind was in a mess.He couldn't help sighing again, thinking: "It would be great if Chen Si was awake." But Chen Si was still asleep.

Gu Fengchun didn't have any clue, so he went to look at the mural on the other side.There are actually not many murals on the other side, but more carved characters.But Gu Fengchun couldn't understand these engraved talismans, because they were written by sharks.Gu Fengchun found it very strange why the mermaid's writing appeared in this place.Especially the characters of the sharks are still in a very backward state.

"King Shark, come here and translate these words for me." Chen Si beckoned the Shark to come over.Gu Fengchun secretly said in his heart: "Perhaps, the answer is here."
