Reversing the World [Quick Transmigration]

Synopsis: When Wen Li woke from his long sleep, he discovered that a few things had gone beyond his expectations. First, irreversible brain damage had cost him some of his memories. Second, he had been bound to a System called World Reversal. System 001: "Among these myriad worlds, countless worlds are unable to become places with a true unfolding history because they cannot escape their Creators' rules. As you travel between them, you might become a cannon-fodder character, a supporting character, a villain, or even the Child of Destiny. Your mission is to reverse each world's original storyline and help it break free from the constraints of the dimensional barriers." Wen Li: "Put it in plain language." System 001: "You get to go cause trouble!"
