“Please, I implore you to save the world.” This is what a goddess in white says to me in a pure-white space. Such is the standard line that suggests the game is about to begin. Please say this stirring line to boys and girls with sparkling eyes! It’s wrong to direct it to someone like me, who’s exhausted from job hunting! When I declined her politely, she flew into a fit of tears; when I agreed to assist her on small tasks out of reflex, she proclaimed: “it’ll be fine if you just help in the Starting-Village Arc. Please guide the Hero!” Then she tossed me into another world. No, this is a world modeled after a game that this gamer goddess likes…

A Heavenly God was transmigrated into a different world right after he died. After arriving in that world, he resides in the body of a handsome young man with a mechanical voice inside his head providing him with missions. It also kept on telling him to brew wine every single day.

Chen Sha came to a world of immortal martial arts and was ordered to take charge of the world’s first sect.

Before his death, the previous chief told him:

“If you don’t become the best in the world for one day, you are not allowed to go down the mountain for one day.”

So he closed himself in painstakingly, crossed the heaven gate in his body, and faced off against the ancient and modern powerhouses…

…

Many years later, Chen Sha recalled the day he went down the mountain,

From the moment he descended the mountain, he was number one in the world.

In the next ten epochs, any gods and demons have returned, immortals and Buddhas have lived in the world, ancient powers and ancient gods have appeared one after another.

No matter how the times change, he has always been No. 1 in the world and has never changed.
