[Star Railway + No Heroine + MiHoYo Universe + All Heavens and Worlds]
While doing his daily work on the Star Dome Railway, Wallas traveled through time and became Wallaus Bass of Belloberg, and gained the power of the Tree of Imaginary Numbers, which allowed him to open a door to a parallel world every week. It allows the powers of various parallel worlds to travel between the two worlds.
Valus used each world to start the era of business in all worlds, and also obtained the power of all worlds, and eventually became the most powerful god.
Bronya: Valus must be the best Great Guardian ever.
Jingliu: If it weren't for Valus, the immortal boat would not be able to escape the curse of the demonic body.
Zhongli: Mr. Wallace is definitely the strongest person I have ever seen, and he is also a man of great wisdom.
Kiana: Without the help of Valus, I would not be what I am now, fighting for the good of the world.
…
Wallace: I am just an ordinary trader from all walks of life...
