Eternal Regret

[Decisive! Invincible! No Mercy!]
When a thunderbolt ripped through the night sky, the blood moon appeared, and the world changed forever. Animals evolved, vegetation grew wildly, and intelligence was awakened.
In just one night, the world was plunged into bloody chaos. The helpless humans were unable to resist the onslaught of the evolved animals and the sweeping plants with awakened intelligence, making countless humans their prey.
However, those with divine runes engraved on their bodies were shocked to find that their runes had also been revived, which gave them incredibly powerful strength.
Three years after the world changed, Gu Changqing transmigrated back to the eve of the cataclysm.
In his previous life, he did not like to engrave anything on his body, but now that he had come back to this chaotic world, the first thing he did to survive and rise up was to invite the world's top divine rune master to engrave the ten evil demons in the world: Rahu, Kirin, White Tiger, Black Dragon, Grim Reaper, Asura, Hades, Skeleton, Great Sage, and Nezha!
He knew that engraving divine runes after the cataclysm would not awaken their power and make them powerful.

Divine Rune Awakening: Starting With Various Divine Runes and Dominating the World

In the sky above the wasteland, the wind, lightning, and spatial cracks that had been stirred up by the collision of divine arts were gradually stopping.

Gu Changqing waited for a response from the tombstone.

When the sky was calm and there were no more shockwaves, the voice from the tomb rang again.

The voice was asking and recalling.

Gu Changqing thought for a moment and replied, "It's been a billion years since the last time Universe City opened."

Hearing Gu Changqing's answer, the tomb fell silent again. After a long time, a wisp of green smoke slowly floated out from inside it.

In front of him, it condensed into an old man in a green robe with white hair and a beard. Noticing that Gu Changqing was sizing him up, the old man said, "There's no need to look. I'm just a wisp of a soul."

The other party nodded and withdrew his divine sense.
