Simultaneous Time Travel: Becoming an Evil God from the Beginning of Mystery

You guys can't sign a contract for this work, but I've finished writing it and I definitely won't supervise it. (New book: I am a lord in the frozen world) has been released. If you are interested, you can take a look. Thank you. This is a Mystery + Harry Potter fanfic. Tristan, who traveled to the world of "Harry Potter" and became the Prewett family, thought that he could change his destiny as long as he relied on the mission system to grow steadily. However, when receiving the reward for the first time, the system was interfered by the "wrong" channel, and the gift that originally belonged to the "Hunter" was tampered with into the "Monster" sequence. From this moment on, his destiny completely deviated from the established trajectory. When the system, destiny and the will of the past are intertwined, a storm sweeping the magical world quietly begins.
