David became a pioneer in the Tiran Kingdom and acquired his own territory, becoming a village chief under the kingdom’s rule.

Although his land was located in a somewhat remote and harsh environment where crops were difficult to grow, and the village was only inhabited by him, David believed these difficulties could be overcome.

David declared, “My territory is open to all realms and dimensions. I won’t go looking for you; you come to me!”

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.

A huge guy is bawling his eyes out. In this day and age? Sure, maybe the world changed while I was away in that other place. I’m not some old-fashioned boomer.But what if that guy is clinging to my pant leg, sobbing and sniffling—And we’re not even acquaintances?Even in modern times, that’s just messed up. Ask any passing kid, they’d agree.So yeah, I shook my leg. He was gross and too close.“The hell’s wrong with you? Crying just ’cause you saw a ghost?” “N-no! I swear, it was really there! You didn’t see it!!”I let the disrespect slide. Barely. He was asking for help and still talking down to me just because I look young?Obviously, I’m not the one who lost his balls. He is.And yet… when I looked where he pointed—Something was there.I threw some coarse salt and looked again.He stared at me like I was insane, but I ignored it.…Yeah. Something was definitely there.It made eye contact.
