This article assumes that Longsu's plan succeeds and kills Jianzi. Fojian kills Longsu in revenge for Jianzi, and then retires sadly and never reaches the top again (this is really, really touching). But what I wrote was not about their mutual killing, but about the Buddha's sword retreating for hundreds of years, being trapped in demonic obstacles, and the Buddha's heart being difficult to reconcile. In fact, it was the death of his best friend that made him retreat in cultivation instead of advancing. Three dreams, one enlightenment.
