The blood moon volleyed in the sky, dimensions collapsed, monsters named "aberrants" poured into reality like a tide, and the fire of civilization was crumbling under the scarlet doomsday.
Ling Yuan was once the leader of the survivors struggling to survive in the apocalypse. He burned his last drop of blood, but still failed to protect the "Morning Barrier" behind him. He was buried under the claws of the throne-level aberrations together with thousands of his compatriots.
When he opened his eyes again, he found that he had returned to a month before the end.
This time he had no intention of repeating his mistakes. Above the surface is a purgatory of monsters and humanity, a city on the sand destined to overturn.
And he turned his attention to the deep and boundless ground beneath his feet.
Also reborn with him was the mysterious core beating in his heart - [Heart of the Abyss].
Take control of the earth, control the torrent of metal, ignite the furnace in the center of the earth, and swallow endless energy.
While the survivors of the apocalypse were still fighting for a piece of bread and a broken wall, Ling Yuan had already established an indestructible and technologically advanced Iron Kingdom deep in the heart of the earth.
"I am the only master of the abyss."
"I am the only light in the eternal night."
"Welcome to my kingdom, but remember, here... I have the final say."
