The Super-Headstrong System

Fate played a joke on him. Other people transmigrated as heirs to powerful families or as their least-favored young masters. And him? He transmigrated as a lowly slave who could barely keep food on the table.

Other people's Systems were better than the last, and their spirit artifacts were all gorgeous young women. He had a System, too, after transmigrating, but a child lived inside it. The child arbitrarily changed quest deadlines, hoarded rewards, and issued absurd quests. If he failed to complete them, it deducted his coins, experience points, and exchange points.

If that's not your thing, don't read. Please don't flame me...
