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

After Huang Di returned from Universe City, he immediately went to find Gu Changqing. After guarding the place for three months, he was about to be surpassed by his juniors.

Arriving at the general office, he saw that Gu Changqing was dealing with some more important matters.

At this moment, Huang Di walked in quickly, "Your Excellency, are you busy?"

When he stepped into the office, his eyes widened and his pupils constricted. Gu Changqing's body emitted waves of aura that made him feel incomparably shocked.

After merely thirty days of not seeing each other, he already couldn't see through the depth of Gu Changqing's strength anymore.

The higher his level, the more he could feel how terrifying Gu Changqing's aura was.

"You're back. How's the situation over there?"

Gu Changqing put down the documents in his hand and threw a cigarette at Huang Di.
