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 Bai won the lottery, became rich, and reached the pinnacle of life. Then, he inadvertently took a picture of the Film Emperor Di Qiuhe being killed. And after reporting this case to the police, he was reborn in a midst of confusion.

He Bai: I don’t have any horrible relatives to abuse. Why was I reborn?

Di Qiuhe: But I do.

He Bai: I also haven’t been betrayed or harmed by anyone. Why was I reborn?

Di Qiuhe: But I have.

He Bai: I just want to have some money to live freely and eat well. I already achieved that goal, so why was I reborn?

Di Qiuhe: I have money, but don’t live freely or well.

He Bai angrily flips the table: So what’s the use of my rebirth! Just to make me suffer again?!

Di Qiuhe (Holding and Touching He Bai): Be my lover, you’re only responsible for eating “lollipops,” you won’t eat any bitterness.

He Bai: Leave!

So basically, this is a sweet story of a naive and cute person who goes back to the past, flaps his little butterfly wings, and helps the man who used to be last life’s big Film Emperor, but in this life, is still a miserable Great Devil King, to walk towards the pinnacle of life (while also dragging someone home)!
