Lin Ye traveled to an urban world similar to Earth, only to find that martial arts flourished here, strange beasts lurked, and the strong were respected. He practiced hard for ten years, relying on the mind and adventure of a time traveler, and quietly reached the pinnacle of martial arts in this world, becoming the only mythical warrior in the world. Just when he felt that his life was as lonely as snow and was about to find a place to retire, a golden finger who claimed to be the "most powerful and robust system" was suddenly bound. The system told him that the world was about to undergo drastic changes, the abyss invaded, and the evil god resurrected, forcing him to continue to "grow steadily", hide his strength, accumulate food, build high walls, and slowly become king. Therefore, Lin Ye, who was invincible in the world, was forced to start a "stable" life with a strange style under the "coercion" of the system (and the temptation of generous rewards): using the strength of the mythical realm to work as a sweeper in a martial arts hall, using the level of an alchemy master to open an online store to sell "health pills", and... The stray cat he rescued turned out to be the Holy Son of the Demon Clan... He originally wanted to quietly build a doomsday fortress, but unknowingly, a group of big bosses gathered around him who thought he was a "hidden master", and the real doomsday catastrophe quietly came during his "steady" preparations.
