I recommend " I Am a Little Ghost." The male protagonist of this novel, Zhang Xiaotian, contracted a strange illness and became a child, living in a world of ghosts. Over there, a kid like him who died at such a young age was pitifully weak, and his aptitude was not good. However, he accidentally obtained a black stone that could change his aptitude. From then on, he began his journey to change his fate. Those who are interested can go and read it. I hope you like my recommendation. Muah!
