My Ex-Boyfriend Is the Boss of an Infinite-Flow World

[A sweet, survival-savvy NPC X a ruthless ruler who goes mad for love]

She only wants to beat the game, but he wants to turn the instance into an eternal prison?

Ruan Sitian is an NPC, and she has a handsome, wealthy boyfriend, Lu Qiubai, who is also an NPC. The two are deeply in love.

Then one day, a player tells her the truth: she is cannon fodder in a C-rank beginner instance in the Infinite World, and her so-called boyfriend is nothing but a low-level, vicious monster that loves to kill.

Right now, the monster is putting on a show of false tenderness before devouring its prey. In a day, she will be brutally killed, just as the plot dictates.

A monster? Brutally killed? Lu Qiubai, who blushes whenever she hugs or kisses him? That has to be a lie!

Ruan Sitian scoffs, then immediately flees the instance with the player.

As the ruler of Instance S4379, Lu Qiubai is notorious throughout the entire Infinite World.

He has a refined, gentle-looking face, but his actions are vicious and terrifying.

No one knows that this legendary figure once willingly disguised himself as an NPC just to stay by a woman's side.

But the girlfriend who promised to love him forever ran off with another man on the eve of their wedding.

Abandoned, Lu Qiubai fell silent in the darkness.

Ruan Sitian goes through one instance after another.

Strange, why does every boss remind her of her ex?

Gloomy, deranged, with a feverish gaze.

Never mind, they probably just all look alike. Lu Qiubai has surely forgotten all about her by now.

Later, Ruan Sitian has no choice but to return to Instance S4379 for a mission.

They say that after its ruler went mad, the instance was upgraded to a death zone.

Unfortunately, when the mission ends, Lu Qiubai steps out of the shadows and grabs her.

Only then does Ruan Sitian learn that the ex-boyfriend she thought was a low-level monster is actually the ruler of the death zone himself.

“Ex-boyfriend?” After pinning her roughly against the floor-to-ceiling window, Lu Qiubai slowly unbuttons the last button of his shirt, his voice dark and ominous. “Did I agree to break up?”

Instance One: [Heartbeat at One Hundred Percent]

“I thought I had found the love of my life, but the one on the other end of the phone was a monster from another world.”

Dating game + cyber cult + mechanical ascension.

Instance Two: [Night Wedding]

“That night, I killed my beloved with my own hands by the salt lake. After they died, a ghost entered the city.”

Exotic ancient tomb + demon worship + cosmic horror invasion.

Instance Three: [The Eye That Watches]

P.S.:

1. Both leads are each other's first and only, one-on-one romance, happy ending. There are many hints from the start, and the events mentioned in the blurb appear later.

2. The heroine grows over time. She seems sweet but is cunning inside. The hero is nonhuman.

3. Cosmic horror, heavy contamination, mysticism, and technological mutation. A lightly ensemble-cast, otherworldly adventure with a strong romance, light puzzle-solving, and mild horror.
