"Baize Tongxuan Jing": Scholar Shen Yan accidentally entered the world of immortal cultivation and was ridiculed as an "ordinary man" because he did not understand the magic. He found a copy of "Baize Tongxuan Sutra" in the ancient cave. In the book, Bai Zexuying can understand the world's magic and teach him to break various restrictions. When the Demon Dao set up a killing formation, he broke the formation according to the method taught by Bai Ze, and even killed the Demon Dao monks: "Ordinary people can also use Baize's power to kill evil!"
