Honkai Impact: The Peerless Demon King Descends from the Sky

"Demon King! Prepare to die!"

A flash of white light, and a boy who looked no different from an ordinary human was transported to the game world he once knew so well.

There is no elemental power here, unlike in his previous world.

There are no strange magic or monsters.

Only the supposedly omnipotent Honkai and a group of youthful and beautiful Valkyries...

Bai Zichen:

"What do you mean by 'I am a Fusion Warrior'?"

"What does it mean that I left behind coordinates in this world that have lasted for 50,000 years?"

"What do you mean I'm a Hyperion Succubus? Hmm... no, that sounds like a positive label..."

Even when Bai Zichen faces countless enemies alone, he will still say that sentence.

"I said I am the Demon King, you Erdo Ryoma!"

(It's funny, full of memes, and has many elements. There's a live stream, and the main theme is that the protagonist is everything.)
