MC gets his previous life's memory back between 5-10 y.o. Because of a birth defect MC can't gather Qi, has white hair & eyes, looks androgynous, etc. Blame everything on the birth defect! He's filial, hardworking, fears females(cuz of a past life experience), etc. Bullied childhood is too cliche so he lived normally. In solitude. No friends. Why? He got too lazy to care about other people after he got his memories back. Does his parents not care? They care but can't persuade MC to come out. Meanwhile MC is studying about the world, plants, animals, mobs, materials, etc from books. How he got the books? God knows. Ok fine he got it all by spending 2.000 Silvers. Books are cheap for plot purposes and because it's too basic. Jade slips can only be used by Cultivators.
