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

Outside Blue Star, Mark Relin stood proudly, his previous humble expression gone.

Isabelle's kind reminder didn't make him stop, even at the brink of death.

He had completely lost himself in the pursuit of creatures from all over the universe.

"The whole universe can see my sincerity," he said disdainfully. "No matter how strong Blue Star is, it can't live without morals and rules!"

Isabelle still wanted to persuade him, but a domineering and cold voice echoed before she could.

"Are you teaching me how to do things on Blue Star?"

The sky outside the planet seemed to have fallen into an endless state of stillness at this moment.

"W-What?" Mark Relin couldn't believe his ears and blurted out in horror, "T-This voice!"

Looking at Gu Changqing who suddenly appeared in front of him, his whole body involuntarily trembled.

"Gu… Gu… Star Emperor Gu… I-I was just..."

Mark Relin stammered, and his face looked worse than crying.
