MTL - Invincible Level Up - v9 Chapter 668 , dead battle BOSS

Markus spent his life piecing together fragments of his past life on Earth, flickers of faces, half-remembered streets, the ghost of a world that no longer existed.Slowly, gradually, he’d finally found his footing in this new world of monstrous beings. He felt grounded, as if his fractured memories could finally settle into something resembling a family.But it all went downhill from there.A lingering touch, a promise, an obsession. As if fate itself was playing a cruel joke, his life begins to spiral down. Gradually tumbling down like a crescendo of madness, dragging him deeper into something inescapable.Every attempt to claw his way back only pulls him further down, like a bottomless pit with no end in sight.How much can a person endure before they break? And when they do, can they ever truly piece themselves back together?

A massive underground labyrinth awaits in an alternate world of swords and magic. With a game-like system much more familiar than spells and magic circles, Beatrice has managed her magic and risen to the position of “strongest”, but she still has her worries.

“Bghohhh!! Bshrrrr…mumble mumble…”

“B-Boo Boo! Stop! Stooooooop!! I’ll…I’ll be crushed!? I-is my, ah, love being tested!?”

Who is the legendary man named Boo Boo who, just by taking a nap, can overpower the Level Cap Holy Swordswoman? A thousand meter dragons and a proud elf girl will also show up, so what exactly is going to happen with these residents of another world!?

“A cheat system? Do you take me for a fool? Nowadays, where can you find such a good thing falling into your lap? Scram from my head. Is this is new kind of fraud? Or is this a murderer training system of aliens that contains the ability of hypnotism?”

“No, I am the chaos that whispers from nothingness, the nightmare of all living beings in the Southern Ten Stars, the successor of the unparalleled God and… your elder sister.”

“…I only have a younger sister, I don’t have an elder sister!”

“No, you have one. I am an illegitimate daughter. It’s just that your dad didn’t inform you.”
