I Can't Be a Sandbox Player

Traveling through the world of immortality, Li Wannian has no spiritual roots, only a system that has not yet been activated. In order to activate the system, he made various attempts. Do good deeds and accumulate virtue, slay demons, practice martial arts, and create power... Unfortunately, no matter how hard he tried, there was no sign of the system being activated until one day, a series of prompts suddenly sounded: "Ding~~~Congratulations to the players, the server of Immortal Buddha is officially launched. I wish you a happy game." "Ding~~~Because you are the first lucky player to enter the game, you will get a lucky gift package." "Ding..." No, it's impossible. How could I, a dignified time traveler, be a sand sculpture player? Oh, is there a reward? That's okay! This novel and its characters are purely fictitious.
