There are two time travel books in this book, each with its own system. What a coincidence is that both of them are the authors of this book. One is the original author, and the other is a fan author.
And our other protagonist is the Reborn. He is a person from another time and space, but he came to this familiar but unfamiliar world because he wanted to repay his kindness.
He thought it was a nightmare coming again, but it turned out to be salvation from his new master.
In addition to Bai Xianyun's book-trading this time, he is also a child of a medical family. Their family uses Bai Dao to cure diseases and save people, and controls poison to harm people.
