Lin Chen, the Immortal Emperor of the Nine Heavens, was plotted by heaven during the ultimate thunder catastrophe that suppressed eternity, and his soul accidentally traveled to a strange world called "Earth". The spiritual energy here is as thin as dust, but it is filled with a violent energy called "qi". Saiyan? God of destruction? Namekian Dragon Ball? It was all new and interesting to him.
In this life, he decided to hide his identity as the Immortal Emperor and resume his path to supreme status as a mortal. He relied on the supreme immortal method to refine "Qi" into the more original power of chaos, and quietly laid out his plans in the dark. He is Goku's most reliable partner, a mysterious opponent who makes Vegeta feel more pressure, and the ultimate variable that even Beerus can't understand in his dreams.
When a cosmic-level crisis comes again, and the dark demon world and artificial human technology are ravaging the world, and everyone falls into despair, he will finally walk out slowly and declare to the entire Dragon Ball world: You know nothing about power.
