Transmigrating into a Game: I'm an Emperor from the Start

[Single male lead, power fantasy] Lin Mo unexpectedly transmigrates into the world of a game.

But after staying there for a while, he realizes that this game world is nothing like he imagined. It seems more like a gigantic vessel.

There is the human realm, where people live; the underworld, where departed souls reside; and the celestial realm, home to the gods and immortals.

A hundred years ago, the three realms fought an incredibly bloody war. Peace was only achieved afterward through an agreement.
