The undersea temple is quiet and serene, like a giant sleeping in the center of the world. On the empty steps of the main hall, Hao Zhi stands beside the prophet like a devout believer, listening quietly to the ancient stories about human history.

The scroll as long as a history book is unfolded in front of us bit by bit. The process of the rise and decline of civilization is as beautiful as flowers, but it withers into pieces after a short peak.

Sigh, the impermanence of things, sigh, the powerlessness of life!

Perhaps more than a mortal like Hao Zhi, even if he is like a great man, standing at the top of the world, out of inner helplessness, he will say such words as "ask the vast earth, who is the master of ups and downs"?

The 500 million year history of civilization is like a castle built on the beach. It looks majestic, but it is actually vulnerable. After a wave of time, there is nothing left.

Fortunately, the civilization of the first season left 13 crystal skeletons.

The civilization of the second season also left a little fire, that is, the civilization of the Mu continent that immigrated to the seabed. After nuclear pollution, the earth is no longer suitable for life to live in for 10000 years. Therefore, the remnants of the Mu Empire built a huge pyramid on the seabed and used chemical technology to saturate a large amount of local seawater and dissolve oxygen, like Hao Zhi now, Can breathe freely.

Therefore, these people survived and started the difficult road of survival under the protection of the ocean mother.

Facing a completely strange environment and bearing the sin of the decline of civilization, they moved forward with difficulty little by little. At first, they could only survive in an environment mixed with saturated oxygen. Over time, some people's cardiopulmonary function has changed, and the structure of various parts of the body is more suitable for underwater life.

Therefore, the first group of people began to set foot in the underwater world outside the oxygen rich area. Although they would come back to replenish oxygen soon, slowly, the process gradually lengthened. They could live in the fuzzy zone between the oxygen rich area and normal seawater. This range gradually expanded thousands of years later.

Finally, those people swam into the deep sea and never looked back

They have forgotten their past civilization and that they once lived on the vast continent. Even after 40000 years of natural purification, the land has been lush and sunny, and they no longer need to return to the land.

The undersea people divided into two groups. Some people guarded the temple of the ancient Mu Empire, inherited the legacy of their ancestors from generation to generation, and waited for the day when they returned to land.

Another group began to adapt to the natural life on the seabed. They gradually degenerated and lost their thinking ability. Their skin became thick and fat filled to keep warm. Their bodies gradually changed shape. Their legs and synthesized tail fins. Due to the lighter gravity in the water, their bodies began to grow and grow. Finally, they became the largest marine mammal in the world

"You mean whales?" Hao Zhi's perspective of understanding the world was refreshed by the prophet again. "Whales also evolved from human ancestors?"

"Yes, in contemporary human archaeology, an important link has been missing between terrestrial limb animals and marine mammals. This link is the period when ancient humans entered underwater life."

"What about another population? Is it your population?" Hao Zhi asked carefully.

Yes, our ancestors strictly abide by the legacy left by ancient civilization and wait for the day when we return to land. We live in this narrow area. In order to prevent degradation, we began to build palaces to exercise ourselves. However, there is a biggest limitation of marine mechanical civilization, that is, we can never develop the thermal mechanical age.

Steam engine and gunpowder, technologies that can never be used on the seabed, have become a breakthrough line. We can only retain the original mechanical civilization and inherit it from generation to generation.

Although we have crystal skulls in our hands, we can't return to land again. Our body structure has undergone serious evolution. Even if we return to land, we can't live for a long time unless we experience another tens of thousands of years.

So we began to mix our genes into the population of terrestrial ancient apes to make them evolve rapidly and have high wisdom, and then use the knowledge in the crystal skull to help them. After 20000 years, your ancestors came out of the forest and began to live on the plain. You know what will happen in the future, Human beings have spread their branches and leaves on this new continent until today.

The civilization in the third quarter, that is, the "new spiritual civilization" created by your mankind, was born. In the early wilderness, you also had the same development path as the civilizations in the previous two quarters.

However, one thing is that you are luckier than us.

"Oh?" Hao Zhi came to the spirit.

The reason why we call you "new spiritual civilization" is that your human civilization development this season is no longer just developing science and technology like the previous two times. In the initial stage of your civilization, you have obtained the help of God and added philosophical thinking at the bottom of civilization, which makes you smarter and more sensitive.

This time, philosophy took the lead and took the lead in science. For the first time, human beings may learn tolerance and self-discipline.

The root of all this is that after 100000 years of long cosmic exploration, the five elders of gandaya civilization returned to the earth!

In 570 BC, Li Er was born in the ancient oriental country and wrote the eternal philosophical masterpiece Tao Te Ching.

In 565 BC, Shakyamuni was born in India, established Buddhism and became an ancient Western Buddha.

In 551 BC, Confucius was born in the ancient oriental country and founded Confucianism, which influenced the development of Oriental civilization for 2000 years.

In 469 BC, Socrates, the founder of western philosophy, was born in Greece, opening up a territory in the history of western philosophy.

In 384 BC, Aristotle came to Greece and developed western culture with important ideological guidance, such as logic, metaphysics, natural philosophy, biology, ethics, politics, art aesthetics and so on.

On the scale of 100000 years of long-distance travel, the time when the five elders returned to the earth was almost the same period. Their long-distance travel in the universe made them realize the importance of the upper limit rule of civilization. As long as a civilization develops blindly and rapidly, it will never break through the bottleneck of self destruction.

So they turned into saints and began to guide you forward from the spiritual world.

In the eyes of human beings, this is an incredible coincidence and an unexplainable phenomenon. Therefore, this great era is called the "axis era" and also called the "sage era". How can they wonder why the eastern and Western worlds, where civilizations were not interlinked at that time, came to their spiritual mentors at the same time?

However, after hundreds of years, human beings did not listen to the teachings of saints as expected. They still began to expose the characteristics of pride and conceit. Therefore, Satan came to the world again. He turned into a human form and appeared in the West and made a covenant with the people there. If the human world continues to degenerate, it will bring the cleansing of the end.

Satan walked barefoot on the water to announce his miracles. He fabricated the story of a whole system of ancient myths, just to guide people to good, and don't repeat the mistakes. Finally, he nailed himself to the cross like he was buried in the ground for sublimation a long time ago, and then reborn, telling people not to despise his prophecy.

He gave the natural law of all things in the universe a God's name, called "God", and then claimed that he was God's child. He also took a new name, Jesus!

"God, Satan and Jesus are the same person! Not God!"

Yes, it's a God or a devil. What's the difference? The prophet said with a bitter smile that when he read heaven and hell, almost all the endings in religious stories point to the final demise of civilization. Mankind will degenerate, and the world will lead to a flood to clean all sins. After that, civilization will regenerate and enter the next cycle.

These are the warnings left by predecessors to the world about the lessons of previous rounds of civilization
