MTL - Travel to a Primitive World to Build Infrastructure - Chapter 67

The world experienced a cataclysmic change, and countless spatial gateways appeared out of thin air.

Memories shape who we are—they define us, anchoring us to our pasts. They are like videos, playing endlessly in our minds.But everything changed one day when people began to relive their memories. However, it wasn’t the pleasant ones that resurfaced. Instead, they were forced to experience their worst moments—or even memories that weren’t their own.Those who managed to survive this haunting experience found themselves watched by strange creatures, and in turn, were granted their powers.As if the world weren’t already thrown into chaos, these same bizarre monsters began to manifest on Earth, threatening humanity with the very real prospect of extinction.Amidst this upheaval, a small, seemingly insignificant beast was born. But it quickly rose to power, only to be betrayed and killed in a cruel twist of fate. Or so it seemed—because somehow, the beast found itself reborn in the body of a human.

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.
