“I am an evil god. Would you like to make a contract?” In “Phantom Heroes Online,” a VRMMO where in-game currency can be converted to real money, a man, worn out by society, decides to quit his job and earn a living through gaming. In this fantasy world of swords and magic, players contract with advanced AI NPCs, aiding and nurturing them. The protagonist, Zephyr, whimsically tells a young girl a lie, claiming to be her savior. Believing Zephyr to be the “god who rescued her from despair,” the yandere girl transforms into the formidable “Reaper Loli,” a top-tier berserker feared as the “Fanatic” across the continent. She rises to become one of the game’s top players, dominating the leaderboards. Unbeknownst to Zephyr and the other players, their actions in the game are actually leading to saving of another world.

Three years after graduating, Chu Mo, who could barely maintain his basic livelihood, activated The Tycoon System, and a bank card with an unlimited credit limit that could be safely used appeared before him. Start a company? Make investments? Buy stocks? In the face of the bank card with unlimited credit, these options seemed to lose their significance. Having already obtained inexhaustible and unlimited money, he might as well live comfortably as an infinitely wealthy tycoon.

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.
