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.

In the training space, the four dragons roared, and smoke mixed with fire rose up.

Two Qilins appeared as endless flames covered the entire space.

The spatial crags were covered by the flames like bleeding wounds.

The two figures stirred up the wind and clouds. Wherever they went, the surroundings shattered like broken glass.

A ripple spread out between the two of them.

In the shattered space, the two of them were fighting like lightning.

If it weren't for this entire area blocking them off from outside, countless galaxies would've already become history.

Gu Changqing had never had such a hearty battle before.

There was a famous saying on Blue Star that a person's greatest opponent was often himself.
