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.

He walked to the side of the stone platform and picked the bell up. After observing it with his spiritual energy, he didn't find anything unusual.

Gu Changqing was suddenly startled, a sense of crisis that had not appeared for a long time surging in his heart.
