Reincarnated in Another World and Become a Missing Body

The male protagonist Zhuo Xu, a game master, never forgets his childhood sweetheart. When the end of the world comes, the entire population of the world is reincarnated. Facing the explanations of the reincarnated goddess, I habitually use game thinking to think that these are not necessary, and just listen to the rules of the game. Under the misunderstanding of the price rules, I choose to pay the price of "losing everything" in exchange for the strongest ability. The actual price is death. When the last 30 seconds of reincarnation came, his small thought of wanting to see her for the last time changed his fate of death and became a ray of longing. After losing memory, emotion, knowledge, material carrier and everything else as a human being, how to retrieve the memory and find her? Who is she? Are they demons, humans, aborigines, or reincarnations who have already paid the price.
