MTL - Rebirth of the Abandoned Woman: Godly Doctor Taizi Fei - v3 Chapter 2319

Xiao Luo and his girlfriend had been in love with each other for four years when she proposed a break up. Because of this, Xiao Luo sped his car in the night and ended up in a car accident. But it was a blessing in disguise as he unexpectedly fused with a high tech system that originated from a universe hundreds of billions of light years away. From this moment on, the entire world started to run amok.....

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.

Hao Ren (literally means “good man”), as his Chinese name suggested, is a good man, and his ideal was to live a restful, comfortable life as a landlord. At least that was his plan before a couple of abnormal creatures rented his house.

Our protagonist Caam is a man from Earth that was reincarnated into this world as a demon. In order to survive, he spared no effort in avoiding the sparks of battle and without noticing it, he became strong himself.
