I recommend "This Side Effect is Awesome". This book was a fantasy novel written by the author, Pingan Xincheng. The main character's Heavenly Book of Reversal Fates could reverse the disadvantages into benefits, but there would be side effects after using it. The main character could absorb the side effects to increase experience. In order to help others cure their diseases, the protagonist, Little Shou, used the Heavenly Book of Reversal to offset the side effects of the healing ability. As a result, his life was exhausted and he died. I hope you like my recommendation. Muah ~
