I recommend the novel,"A Hundred Ways to Become Immortal." The male protagonist was considered a waste. He bought all kinds of waste all year round, including waste pills and low-grade materials. However, he was not picky. As long as he could be recycled, he would not let go. Through continuous acquisition and cultivation, he eventually became a top self-cultivator in the immortal world. I hope you like this fairy's recommendation. Muah ~😗
