A Job? I'm an Expert at That [Quick Transmigration]

[The story arc of supporting character Si Cheng'an from Three Sentences to Make the Protagonist Bottom Top Me]

The blurb isn't finished and I haven't figured it out yet. I'll revise it later, but the protagonist won't change. It'll still be this bug.

Blurb:

Si Cheng'an is a workaholic.

Born into an ordinary family, he has to support his eight-hundred-year-old mother and take care of his eight-month-old little brother. Every day, he works himself to the bone and never dares slack off.

After three hundred years of toiling away, he checks his savings and finds they're still at zero.

Si Cheng'an has an epiphany: working for someone else like a beast of burden won't make him rich. Only starting his own business and becoming the boss can bring wealth to his family.

After three years of working himself to the bone, Si Cheng'an loses every penny and ends up owing the main System space three hundred million points. He can only return to the little worlds to pay off his debt.

World One: I Became the CEO's Mother

World Two: The Merman Prince Is My Dad

World Three: The Difference Between a Celestial Master and a Ghost

World Four: The Demon Princess Has Style

He passes through the protagonist's world once, then again, and again and again!

Theme: The struggle of a supporting character
