Revenge Begins with Transmigrating into a Ghoul

Every flower and blade of grass is a world of its own. Everything in existence possesses energy, and every move you make generates energy. Regardless of cause and effect, time or space, all things are built from energy. Every world has a force that sustains it, known as its source power. Every world has one, and if that power disappears, the world itself will vanish.

Across the countless levels of the universe, there is also a force that keeps the cosmos running, called the cosmic source! The source power of every world and universe is different, some stronger and some weaker. Its strength can be determined by the level of that world's system. The powerhouses of the countless universes have all mastered the source power of at least seven universes, and wield sources of above-average rank!

There are two ways to obtain cosmic source power. The first is to defeat the ruler of the universe and absorb their source power. The second is to defeat the universe's enforcer. Enforcers are born alongside their universes, and defeating one lets you rule that universe!

There is a legend among the countless universes: if you see someone wearing a mask, a seemingly ordinary powerhouse traveling through the cosmos, you must stay away. Never provoke them, or you will die a horrible death. The people of the countless universes only know him by one name: Wu!

This book is also known as The Legend of Wu or The Biography of Wu.
