MTL - Medical Master - v8 Chapter 467 Even if you use it, it will consume you.

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

He was a wealthy and mysterious financial backer who had appeared before her when she needed money the most. After the courtship, she took the money and left.

Big news: Fu Xuechen, the great God of mathematics department, is making friends with the little cutie of the Chinese department.

Her roommate pressed her: “I heard that the great God is chasing you!!!”

Ran Xing with a blank face: “He didn’t chase me!”

Her roommate asked, “What is he looking for you?”

Ran Xing looked at the sleeping God: “Lying on the desk next to me and sleeping.”

Roommate: “…”

Fu Xuechen is a patient with severe insomnia. His dark circles are comparable to those of Gaara. He was prepared for sudden death long before he met Ran Xing.

But after one look, he fell asleep on his desk.

He simply asked for her timetable and slept next to her every day.

Later, Ran Xing rented a house outside. Her roommate asked her for something and rang the bell. But Fu Xuechen, who was only wearing pajamas, opened the door.

The roommate quickly apologized: “Sorry, I went to the wrong place.”

Fu Xuechen said lazily: “You didn’t go wrong. She’s inside!”

Roommate: “…”

She said that the great God did not chase her!!!
