The disaster of the red sun came, and the scorching radiation turned the surface of the earth into purgatory, and the embers of human civilization were forced underground.
In the previous life, Chu Yuan was one of the last resistance leaders of mankind. He gave everything he had but gained the most complete betrayal and despair. When he closed his eyes in the ruins of the shelter with endless regret and unwillingness, he found that he had returned to ten years before the end.
After a new life, the warmth and ideals of the past have long been replaced by cold hatred and reason. Chu Yuan no longer wants to save the world. His only goal is to use his prophetic knowledge and use all his resources to build himself an underground kingdom that will never fall - the "City of the Abyss".
The outside world is a human purgatory struggling to survive, wildly mutated underground beasts, and enemies from past lives who are eyeing them.
Within the abyss, Chu Yuan is the only law.
This time he no longer believed in anyone but the absolute power in his own hands.
When the doomsday bell rings again and the whole world lingers under the abyss, Chu Yuan has long been the supreme underground monarch.
