In the Extreme Cold Apocalypse, I Built an Underground City-State

A sharp tug at her earlobe, and Xia Qingxin was forced to wear an earring smeared with zombie blood.

Her former roommate laughed triumphantly. She had stolen Xia Qingxin's boyfriend and her space necklace, and now she wanted to take her life, too!

She was dying, but she felt someone else deserved to die!

Xia Qingxin fought back as she died, but only managed to burn a layer of skin off the scumbag and his shameless lover. As she lay dying with her eyes wide open, the earring suddenly flashed. "Would you like to bind the Underground City System?"

"Bind it!" Xia Qingxin transformed into the lord of an underground city.

What did the surface temperature dropping to minus sixty degrees have to do with her? She could soak in a hot spring underground.

They said there was a mysterious base, not built on the surface but underground. They said it was as warm as spring and overflowing with wealth. They said you could trade crystal cores for warm clothes, medicine, and food. They said the base chief had planted a huge vegetable garden, with fruit and vegetables measured by the ton. They said that even during the surface's extreme cold season, a few days in the base's safe house and a handful of crystal cores could keep you from freezing to death!

The news spread like wildfire across the world. Xia Qingxin looked worriedly at a mountain of crystal cores, while people outside fought tooth and nail to rent rooms, and her former roommate was down on her luck like a stray dog.

It all started with that earring smeared with zombie blood. You couldn't ask for a clearer case of trading something precious for something worthless. "Thanks for the gift. I love it." Xia Qingxin smiled as she smashed her former roommate's head in.
