MTL - People Are In Marvel, Behind the Scenes - Chapter 340 Invincible Doom (below)

Luo Yi, a high school dropout in his original world, was isekai’d into the world of the Witcher 3. Starting out as a weak boy named Roy in the village of Kaer, Lower Posada, he was determined to grow stronger, no matter what it took. The first step toward becoming a legend was to kill. And his first kill was… a rooster. ‘You gain 1 EXP.’ Of course, Roy had his own cheat system like all the other isekai protagonists. His first step to becoming a legend started now…

Qingyun was probably the only villain who suffered this much.

For hundreds of years, a protagonist has always been barking at him and attempting to harm him, but just couldn’t kill him.

When he spent his days bedridden like a dying man, his life was no better than that of the dead.

People respected him, feared him, secretly cursed at him, but he just wouldn’t die!

But he, the ultimate BOSS, has become an insignificant cannon fodder only to be manipulated and destroyed?

That’ll never happen.

A certain green-eyed man: Cutie, come into my arms.

Qingyun: Heh heh, Lao Zi will teach you how to behave.

*Ding* the world’s most ferocious little cutie has come online~

- Description from Novelupdates

Painfully shy and conflict-averse, Yun Ruoyan is a scion to a noble house only in name, a puppet embroiled in political machinations beyond her ken. At the tender age of eighteen, poisoned and at death’s door, she finds herself thrown out into the streets. Her relatives have all been executed, betrayed by her dear husband and her cousin. With her dying breath, she curses her own weakness and swears revenge.

When Yun Ruoyan awakens once more, she is thirteen, transported five years into the past by the will of the heavens. Her death-defying experience has changed her: no longer is she the malleable creature she once was. But more questions await at every corner—what is the truth behind the birthmark that disfigures her appearance? What are the circumstances surrounding her mother’s mysterious death?

Will the phoenix rise from the ashes, or will she fall once more in thrall to fate?

5 years after the world changed, the final boss appeared.

The top five players in the world, including Specter Seo Jun-ho, finally defeated the Frost Queen…

But they fell into a deep slumber.

25 years passed.

“A second floor? It didn’t end when the Frost Queen died?

Specter awakes from his slumber.
