Time!

She realized that the path she walked was time, and every time she moved forward or backward, the changes that took place around her were the Songhai Cangtian for hundreds of millions of years.

In a hazy way, Nina saw a magnificent space city-state, whose architectural techniques and technology had advanced far beyond human imagination. Their source of energy is just as speculated by the Dyson sphere theory, they first send many man-made crystals with self-replication ability into the orbit of a natural star, and soon these crystals begin to absorb the energy emitted by the star and start to replicate themselves, and finally form a shell on the outer edge of the star, and begin to continuously extract the energy emitted by the absorbed star into their own city-state.

They create buildings very quickly, and they don't need a lot of workers and large planetary construction machines, but through edited instructions, the crystals with memory ability spontaneously expand and grow into a building, and their buildings are generally highly symmetrical hexagons, like delicate and intricate silvery snowflakes in space.

Taking a step forward, time passed rapidly in front of Nina's eyes, and Nina saw that they had built a huge gate-shaped building with hexagonal buildings, which were classical and beautiful, sacred and noble, and even a little similar to the architectural style of human temples in ancient Greece, but in terms of volume and exquisite craftsmanship, they were far from being able to catch up with humans. At first, Nina thought it was just a work of art that they used to demonstrate the powerful architectural abilities of their people, and had no real use. But soon Nina discovers that she is wrong. Soon, countless energy transmitters from all directions converged here, converging all the energy from distant stars here. The gate was opened, and all the members of their clan boarded the spaceship and walked into the gate, which continued to shrink and finally became the appearance of a civilized egg.

"Step into the Egg of Civilization...... Self-sealing? Nina wondered what they were doing, and she thought of the pattern she had seen in ancient books, the first connected serpent, devouring its own tail while looping endlessly, and the nesting of large and small universes seemed to be like this...... There must be some point here!

Time shifted, and soon the civilization egg entered the interior of the planet, and a spaceship left by that civilization was always guarding the outside of the civilization egg, the passage of time erased the traces of civilization's existence, and all the relics of the past were buried in the long river of time.

"Lighthouse! Wait a minute! Nina suddenly realized something, but at this time there was no one else here except her, and even if she found a big secret, she couldn't tell it.

"This is a lighthouse!" Nina recognized the ship's appearance, "That'...... Is this the earth when it was born? ”

Nina sped up her pace, she trotted on the axis of time, the rapidly rotating stars like the hands of a clock, time traveled to ancient times, and an asteroid rain began to fall in the star field of the civilization egg planet.

Like a long arrow shot from the sky by a god, one of the small stars was in the middle of the planet that was still in a lava state, a huge shock came from the earth, and the tumbling magma ocean bloomed, revealing a demonic face, under the baptism of various extreme geographical phenomena, the planet seemed to have fallen into the terrifying hell described in the ancient legend, and the surface structure began to change dramatically.

Separated from the comfortable magma in the center of the earth, a brief star ring was formed, but it was obvious that the structure of the planet could not support the star ring, and soon the star ring began to gather, enveloping the spaceship moored in low earth orbit, and the accompanying spaceship left by the advanced civilization was buried deep under the rock.

Then there was a long dead silence on the blue planet, and it took a long time for Nina to see the thunder and lightning rolling in the primordial ocean, and the simplest biological structures were born in this boiling ocean, and everything sprouted, and the sprout of living things was very short in the history of the planet, but it was extremely beautiful, and Nina couldn't help but slow down.

She was dazzled by the brilliant biological development scroll, and even forgot that this was the history of her own planet, until she saw a familiar figure appear, and Nina reacted...... It was here that the fireworks of human civilization appeared.

The top of the ecological niche has changed hands several times, and one of the tribes from Africa stands out, and on the way to hunt, they encounter a higher civilization creature that has come to the earth to explore the situation of civilization eggs, which is nearly three or four meters high, and the olive-shaped body is surrounded by translucent tentacles.

One of the prophets who had seen the gods told his people that the gods had conveyed a very good prophecy to him before they ascended to heaven, and the gods said that the descendants of their group would one day rule the entire earthly world, and he hoped that his descendants would trust the will of the gods and pass on their bloodlines and footprints to more distant places.

Of course, Shur has never said such a funny thing, this is all imagined by the ancestors of mankind after awakening to the cognitive revolution, and at that time, there was only one creature on the earth that could imagine and lie.

After the death of the Prophet, there was a dispute among the tribe over the course of the future development of the tribe, and the opinions of the two sides were at odds among the tribe. In the end, there was even a war of force, and people raised the weapons they would have used against the enemy and began to attack their own compatriots. The intensity of the battle was unprecedented, even more intense than the males' struggle for mates during puberty.

The new prophet lost control of the emotionally heated tribal villagers. Eventually, it was announced that the group would be split in two, with a group of adventurous youths leading some of them to leave the tribe to chase the prophecies of the gods they believed to be true, while the other group would leave the old people with the old people in the well-established villages to keep the legacy of their ancestors.

After difficult negotiations and mediation, the two sides reduced their armed clashes, reduced their revenge against each other, and finally agreed to the proposal of the senate, and the people of the village held a grand assembly, and those who were going to leave were used in front of the altar to swear to their ancestors and gods with blood.

The brave people left their tribes in great force, and their descendants traveled all the way up the African continent, across the Red Sea, to the Eurasian continent, and from here spread their people to the entire earth. Having established its own civilizations all over the world, it is about to usher in a new era, the dawn of the enlightenment of human civilization.
