The World's most Overpowered Side-Character - Chapter 378 I Need A New Heart.

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.

System: You are now a lowly male supporting role, a passerby who wants to go offline at any time, please keep secretly and grow vulgarly.
Shi Yan: Very good, thank you for your suggestion.
The first world: Shi Yan, as a little prince born in a cold palace, made himself an emperor.
The original male and female protagonists, under his witness, became grudge couples.
The second world: Shi Yan, as the youngest son of the princess who died tragically, made himself a powerful minister over ten thousand people.
The original male and female protagonists, under his witness, became grudge couples.
The nth world: Shi Yan, as a genius in the world of comprehension, has made himself the number one powerhouse in the Three Realms.
The original male and female protagonists, under his witness, became grudge couples.
The system feels that something is wrong.
Shi Yan instead persuaded him: Let the male and female protagonists come together in the end no matter what the circumstances are, isn’t it the self-cultivation of the tool man and the male partner?
