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

On Blue Star, deep within Mount Kunlun that was shrouded in clouds and mist, a majestic dragon's roar suddenly rumbled.

Afterward, a huge black creature was seen rolling in the clouds.

Upon closer inspection, it was actually a black dragon that was tens of thousands of feet tall, big enough to cover the sun.

"What's going on? Is there really a black dragon on Mount Kunlun?"

In the central city, Xuanyuan Wangrui, Huang Mengguo, and Long Zhanguo, who had just received the notice, rushed to the central hall in a hurry.

When they saw the black dragon in the projection, they were shocked.

Huang Mengguo asked suspiciously, "I remember that three years ago, Star Emperor Gu had slaughtered the Kunlun True Dragon. Why is there another black dragon after three years? What is that mountain's background?"

Xuanyuan Wangrui smiled. "It seems Star Emperor Gu's real mount has arrived. I'll contact him first."
