Human beings only regard the gray fog as a doomsday natural disaster, but they do not know that it is a reckoning for civilization that spans three thousand years. The jade pendant engraved with original runes slept for thousands of years. Ling Chen, who was reborn from blood, carried the last fire of the earth's ancient civilization. The alien ring of the Blue Circuit is bound to the harvesting system. Shen Jin takes charge of the technology and legion of the Ember Realm, transforming into a liquidator of civilization, and is dedicated to resurrecting the home planet. One person relies on the original power to defend his homeland, and the other relies on Jin energy technology to save his people. The two are neither heroes nor villains, they are just pawns who bear the shackles of civilization and cannot help themselves. The jade pendant wakes up, and the dark gold runes tear through the gray fog; the system operates at full capacity, countless embers modified bodies wreak havoc in the streets, and embers burn throughout the city. The end of the world is a cruel choice: wait for civilization to be annihilated, or break through fate and find new life. Ling Chen's eyes were filled with the coldness of six years of blood and corpses: "Who are you to decide the fate of mankind?" Chen Jin rubbed the cracked ring, hiding three thousand years of wandering and loneliness: "I just want to redeem my people." A game of fate step by step, hardcore survival throughout. The two civilizations are in perfect conflict, there is no absolute good or evil between good and evil, and the thousand-year deadlock finally faces the ultimate showdown. Ling Chen clutched the hot jade pendant tightly and looked at the black-robed figure in the gray mist: "Chen Jin, let's do it. The city is burning with flames, and we have no way out."
