At War with Myself

This book is also known as "My Other-Selves in Different Worlds Are All Super Bosses", "A Multiverse War, Where My Greatest Enemy Is Always Another Version of Me", and "Oh No, I’m Surrounded by My Corrupted Selves"

…

Xu Wuya had just stepped onto the stage to give a speech as the strongest high school student when he witnessed the extinction of humanity.

And all of it happened simply because monsters beyond time were fighting on a world-spanning scale, and humanity got caught in the crossfire.

Who could blame monsters with power like that?

They slay death, destroy thought, break the future, deny fate, mock faith, and sit at the pinnacle of all things. They cast shadows over the time that submits to them, look down on everything in the mortal realm, and trample all in their path to make their will known.

The only things they see are one another, locked in battle.

Xu Wuya burned their images into his eyes and was astonished to discover that every one of those monsters was himself, shaped by a different choice.

“I don’t know what I went through to fall so far and become like that. I don’t know what you’re fighting for, or why you look down on life.”

“But if killing every last one of you is the only way to take back my happiness, then let’s fight.”

“I will make myself your enemy. I will spread the flames of war across the countless worlds we have colored with our presence, reject everything you stand for, and drag you from your thrones.”
