Hundreds of millions of years ago, the ancient martial sage suppressed the heavens and used his Taoist seal to cause chaos among all races. The fragments of the martial seal were scattered in the world, silent under the urban fabric. In today's technologically prosperous cities, the remnants of all races are dormant in secret, using modern civilization to cover up their ambitions for recovery. The inheritance of human martial arts is almost cut off, and the crisis is quietly spreading. An ordinary boy accidentally picked up an ancient martial seal. The ancient martial arts that had been dormant for hundreds of millions of years suddenly awakened, and the breath of martial arts broke through the confinement of urban steel and concrete. He uses the modern city as his arena, ancient martial arts as his blade, slays alien minions in the flash of neon lights, and explores the true meaning of inheritance in the collision of technology and martial arts. Travel through the secret realms of the city, gather the power of awakened people, resist the invasion of all races, rekindle ancient martial arts in the modern city, and compose a magnificent epic of human martial arts protecting their homeland.
