Jiang Yan, a top modern martial arts master, traveled to the doomsday wasteland of 2150 due to a time experiment. At this time, the earth was shrouded in "ash", animals and plants mutated, and humans huddled in safe zones to survive. Relying on his domineering and ruthless character and martial arts skills, Jiang Yan quickly gained a foothold, gradually awakening to the bloodline of the Ancient Flame Emperor, and able to mobilize the power of the Ancient to fight against the Gray Tribulation monster. He cooperated with the independent archaeologist Ye Zhao to interpret the ruins of the prehistoric era and discovered that the root cause of the apocalypse was the resurgence of the "chaos demon" in the prehistoric era. In order to save mankind, Jiang Yan led his forces in a cross-border campaign (entering the prehistoric plane and the Chaos Demon's Nest). After many life-and-death battles, he finally killed the Chaos Demon, crushed the heaven and earth, and led mankind to rebuild their homeland.
