- Description from novelupdates

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.

Cain was an ordinary boy who loved creative works, especially when it involved anime and games. Suddenly, he found himself in a strange space with an extraterrestrial creature, a cosmic horror called Bishop that he couldn’t explain in words besides scary.Given the authority of a King, he was tasked to create dungeons in the multiverse in order to change his future. He had been turned into the Dungeon Maker. The more known his dungeon was, the stronger he became!Rias: What are you? A Devil?Dante: Now, now. What are you? Wow, I drank too much. Look at her, a sexy devil.Zoro: Where am I? Is that a sea monster? Good, I will bring meat for Luffy.Helldiver: For Democracy!!!All worlds became connected due to the dungeon. However, don’t worry!Everything was under his control.
