Anonymous NPC, but has BOSS health bar

The large-scale holographic online escape game "No Turn Back" is launched.
Countless beta test invitations were distributed all over the world, and the online discussion became increasingly heated. Xiang Liangyu looked at the NPC invitation in his hand and fell into deep thought.
After being forced to become a game NPC, she discovered...
It’s so cool!
Until she found something that looked like a blood bar appearing on her head, and it was gradually decreasing.
Xiang Liangyu was shocked: Am I not an NPC? Why do I have a health bar?
In order to survive in the game, she had to step out of her comfort zone and into the dangerous main line area. The anonymous NPC who was supposed to lead the players and issue quests actually became a lackey of the monsters.
World 1: Zero Island [Completed]
The Round the World ship sailed into the Atlantic Ocean and encountered a huge cloud storm that had not been seen in a century. All the engines were scrapped and it was pushed into the depths of the Atlantic Ocean by the wind and waves.
"It is late at night. Guests from afar, please do not linger in the dense woods. Be careful not to fall into a deep cave and become a delicacy for criminals."
A girl full of lies and an unscrupulous girl x a refreshing and classical golden-tailed mermaid
The players discovered that there seemed to be a lackey in their team.
Xiang Liangyu: Brother Yuguai, they are over there.
Xiang Liangyu: Brother Aboriginal, they are going to do bad things.
Player: Where is my report button?
World 2: Blood and Roses
Absurdity and reality are intertwined, blue and darkness are set off, and when night falls, the eyes hidden in the crowd are slowly opening.
"Escape, when the dark blue night rises, when the savior's whispers sound softly."
The Golden and Angry Bird of Paradise X The Hungry and Gentle Werewolf
The running dogs are still there, but they have turned into birds.
Xiang Liangyu looked pitiful: I'm hungry, so I'll eat a player.
Player: Are you done yet?
World 3: Killing the Campus
When the bell from the bell tower rings throughout the campus at 7 pm, students are not allowed to walk around the campus without permission, because the campus at this time is no longer a daytime campus.
“Is the direction indicated by the safety sign really a safe place?”
The flashy and cool senior sister X seems to have albinism but is actually a vampire principal
The lackeys are getting more and more excessive.
Xiang Liangyu was extremely proud: My partner is the principal.
Player: A dog relying on the power of others!
World Four
…
Later, the game should have continued in this cycle: death, rebirth, death... But the game without an end was like an infinite cycle of time, and Xiang Liangyu was tired of it.
So she became the common enemy of rules, gods, and rulers.
Once again, she was against the whole world.
Only this time, she wasn't alone.
