The Senior Sister with a Universe in Her Heart

I transmigrated after crashing into my senior sister's arms, and to make matters worse, my starting point was a shattered Annihilation Sequence?

Everyone sneered: “You're beyond saving in this life!”

Xiao Chen: “Hah! I have the Devouring System, and I can devour every incomplete law under heaven! I'll prove my path and become the Supreme True Immortal of the Universe!”

I planned to make a quiet comeback and amaze the entire universe, but then I ran into a True Immortal of the Universe:

“Huh? Immortal, wait a moment... Why do you look a little like my teacher...?”

What the hell! I transmigrated into a useless loser, while you old man transmigrated as someone who could rule the universe?

Wait, old man, what did you say?

I didn't actually transmigrate?
