This is a "tragic" story in which a masked person paralyzed into the world of cultivating immortals, and then took in a well-behaved and capable apprentice (who he thought he was) in the world of immortality, and was finally betrayed by his own well-behaved apprentice. By the way, the author said that this is his first time writing an article, and his writing style may be a bit bad. I hope readers can forgive me (*^_^*).
