I Compete with the Richest Man to Show Off Our Wealth

Luo Luo's parents died in a car accident. Her boyfriend teamed up with her cousin's family to swindle her out of the 3 million yuan inheritance, leaving Luo Luo nearly reduced to scavenging just to save enough for college tuition.

One day, she finds a junk System. If she can spend 30 billion in an alternate world's hyperinflation economy within three months, her parents will come back to life.

At an auction, Luo Luo competes with the richest man for antiques. At an upscale restaurant, she competes with him to book the entire place. At a car dealership, she competes with him for limited-edition luxury cars.

The richest man: "...Are you trying to get my attention? I'm not that easy to fool."

Before long, Luo Luo has hired three pretty young men to play mahjong with her.

The richest man: "...So you really were doing it on purpose."

Three months later, Luo Luo brings her parents back to life and returns to school. Her ex-boyfriend and cousin mock her for finally saving enough tuition to attend, but then they see the enormous diamond on her left hand. The richest upperclassman, whom the principal has just invited back to give a speech, walks over to Luo Luo and warns them:

"Stay away from my wife." Every living thing should stay away from his wife!

A flashy, domineering heroine who loves showing off her wealth vs. a jealous hero who is obsessively protective of his wife
