Across the myriad worlds and countless realms, every world has a dazzling protagonist who enjoys the company of beautiful women and speaks of all under heaven. Yet in the corners the world overlooks, there are always people who give far more and end up with nothing. They are called supporting characters, until one day their cries of rage find an answering voice. With my own body, I shall fulfill your wishes. As a supporting character, I shall crush the protagonists of myriad worlds. With the Great Dao as my foundation, Xu Yi is born to battle the protagonists of myriad worlds and the Heavenly Dao of all heavens: with all I have given, I shall fight for the fortune you have gained.
