Quick Transmigration Experiment: Let Your Heart Decide Between Collapse and Repair

[No Fixed Male or Female Lead] [Nontraditional Story] The protagonist has both a malicious System and a kind System, but they only offer guidance. The System is not responsible for the path the protagonist chooses.

Ever since the cheeky System Jianjian became conscious, it has had no memories and has always thought it was a person. It has nothing, and its space is bare as an empty house, except for ten hollow hearts floating overhead. While wandering around and getting into trouble, it discovers that whenever it does a good deed, one heart gains a tiny red shard, while a bad deed adds a black shard to another heart. When both hearts have a shard, a voice sounds in its mind, telling it that once all ten hearts are filled, five entirely black and five entirely red, it will learn everything and regain what it lost. It has transmigrated into the world of a book.
