At the same time, he awakened the system of the heavens and distributed rewards through the system. As long as he acted like an elegant villain and conquered the heroine, he could get rewards.

If you travel back to a romance anime, who would like to have a separate storyline with the female lead?

Unknowingly, Linde has transformed the universe into his own pasture.

When Lin Yun, a 996 office worker, is "taken away" by a truck on his way to work, he opens his eyes and is reborn into the everyday world of anime he's always dreamed of. He thought he'd enjoy a peaceful high school life with familiar characters, until one day—a bloody elimination tournament called "Instance" suddenly arrives, ripping apart his warm daily life and dragging the world into a brutal "Civilization Selection."

Faced with this sudden prelude to doom, everyone blindly pursued the "evolution" power granted by the system, but Lin Yun stood by and watched with aloof eyes. The mysterious panel in his mind, towering over the entire universe, allowed him to see through the conspiracy behind the copy and the true nature of "evolution"—it was merely a disguise for the captivity and harvesting of higher-dimensional beings.

To protect the hard-earned warmth of his daily life, and for the girl he cherishes most, Kotobuki Tsumugi, Lin Yun resolutely embarks on a path of dominance that defies all rules. Hiding his edge, he quietly cultivates his own "Hunyuan Martial Arts," tempering his strength to the limit. Under the guise of peace, he and his childhood companions form the "Starry Sky Oath." Acting as a prophet, he forges a path that will drag the world into his new order.

He's not a savior, but a chess master outside the chessboard. While everyone else struggles to survive in the dungeon, Lin Yun is already controlling the situation behind the scenes, aiming to finally break free from all constraints and achieve absolute freedom and control—never again to be constrained by anything!
