Storyteller's Last Page

Traveling back to ancient times, my name is Lu Wangli, you can also call me Cheng Xiangming. I just want to be a storyteller and wait to die. But among the relics left by his father, there is an unnamed book. There are two chapters written on it: "Projection" and "Transaction". The so-called projection is to turn one's wishes into special abilities. The so-called transaction is to use the principle of equivalent exchange to exchange one's own things for other things. Later I discovered that everything has a price - for example, I can never really keep Sister Li.
