Honkai: Star Rail: Max-Level Sign-In, I Take the Astral Express Head-On

Su Mu transmigrates into the Honkai: Star Rail universe and awakens a god-tier sign-in System!

The difficulty is hellish from the start? Su Mu responds by activating a "Void Body" and physically slamming into the Astral Express in space, bringing it to a dead stop in the middle of a warp!

Himeko is stunned: Is this guy's body made of vibranium?

But that's only the beginning!

On Jarilo-VI, he ignores the laws of physics, crushes a Stellaron with his bare hands, and conjures an artificial sun at the push of a button, leaving Cocolia dumbfounded!

On the Xianzhou Luofu, he activates GM administrator privileges, drags Phantylia the Undying into the "recycle bin" and deletes her for good, then hits Aha the Elation with a "server-wide mute"!

Qlipoth starts tearing down the wall in the middle of the night: Big brother, stop kicking it! I'll take it down myself!

Firefly: Only by his side am I a complete girl, no longer a cold mecha.

Fu Xuan: How is this a mere variable? He's a living ancestor who attacks from a higher dimension!

From crafting conceptual curios by hand to rewriting the universe's underlying code, Su Mu does whatever he wants in this universe. Even the Aeons have to offer him a cigarette!
