Getting the Tao Leads to Disaster

In this world, there can only be one immortal on one avenue. There are four people who practice swordsmanship. One wants to cut off everything, one wants to protect the common people, one wants to slay the inner demons, and one wants to rule all living beings. They all practice swordsmanship, but only one of them can survive. Whoever becomes an immortal first, whose sword is the truth, and other people's swords are a joke. —— What's even more terrifying is the monasticism itself. Every time a practitioner of the Way of Cutting off a fetter is cut off, his or her cultivation level will improve by one point. Cut off love, cut off memories, and cut off your own emotions and desires. At the end of the practice, the person standing in front of you is no longer a "person", but a monster that can only perform the action of "cutting". You asked him why he beheaded you, and he said, "I don't know, Tao asked me to behead you."
