Ascension of All Races: Obtain a Double Life at the Start

The remaining soul travels to another world and shares the same body with a beautiful alchemist. Unlike other time-travelers, Shangyu is obviously very strong, but he has no ambition to rule the world and no desire to be king. Everything he does is to make up for the regrets in his life. However, this world has been persecuted by travellers. The "enemy killers" whose goal is to hunt travellers are powerful and mysterious. Shangyu has been caught in life and death crises again and again... At the same time, a disaster that destroyed the world quietly came.
