Work or Enter a Dungeon? That Is the Question

[The story stays focused entirely on the heroine, and the clues she gathers are always exactly in sync with what the readers know. This isn't a power fantasy in the traditional sense, but leans more toward rigorous deduction. Thank you, everyone!]

Han Zhenyu used to think that doing drudge work for capitalism day after day was surely the most miserable thing in the world.

That was until the day she heard the instance alert:

“Instance loaded successfully!”

From then on, Han Zhenyu was plunged into a series of bizarre, terrifying and horrifying events, which even dragged the people dearest to her into the mess.

And the instance shamelessly kept promoting itself:

“Do you find your life bland and dull? Do you think that, despite your talents going unrecognized, you'll never amount to anything?”

“Come join the thrilling adventures of infinite instances! You'll find endless excitement! Push beyond your limits! Become someone new!”

Han Zhenyu: “Heh. Pure clickbait, false advertising.”

Gui Haining: “Brothers, smash it up for me!”

Instance: “Wait, wait, there are prizes.”

Han Zhenyu (reaching out): “Hand them over!”

Instance: “Hehe, I already gave them to you~”

Han Zhenyu: “Brothers! Smash it up for me, aaah!”
