Inside the Cave of Obscenity - Chapter Volume 1 4: Adventurer 3

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.

Xiao Bing, who used to be a top soldier in mercenary and came back to normal life because of the death of his best friend. He started over, played dumb and coped with difficulties. He stood on the bones of others and held beauty by his side. Finally, he succeeded and became the emperor of the city.

“Brother Bing, please protect my little sister as well as my families carefully. I feel lucky to accompany you during these 6 years. It is my honor to go through fire and water with you. I’m not regretful!”

I’m not regretful!

Thinking of what Su Peiya had said before dying, Xiao Bing clenched his fists tightly and cried. He made a decision to protect Su Peiya’s families before finding the spy of Long Men and to make rightful claims for Su Peiya.

Xiao Bing did not love Su Peiya, but he regarded her as his only best friend!

He unfastened the seat belt when the plane landed safely. Looking at the urn in his hands, he sighed, “We have arrived at Jiang City. You get home now, Peiya.”

Tired of the schemes and strifes of city life, Bei Feng finally returned to his hometown in the countryside

While picking asters ‘neath the Eastern fence;

My gaze upon the Southern mountain rests;

Rearing a few chickens and ducks, I shall lead a simple and leisurely life!

However, who would have thought that fate would play a huge joke on Bei Feng? All kinds of magical items and beings of the Myriad Worlds could actually be fished out of the Ancient Well in his yard!

Even a chicken reeled out of the well ended up chasing Bei Feng all over the yard and beating him black and blue! Speechless and aggrieved, he asked the Heavens: if, that day, he’d fished out a Dragon instead of a chicken, what would’ve happened to him!
