As of then, NPCs who had reached Mystical Realm were very rare and practically invincible existences in World of Martial Arts. They had all necessary skills: a body fortification technique, a lightness skill, a high-tier martial art, and a secret technique. Their equipment and weapon were also extraordinary. They had an attack system that they declared entirely their own, and because of how rare they were, it made them even more difficult to deal with.
Hence, even players with high-tier martial arts would feel nervous when they ran into NPCs in Mystical Realm. They could only run when they caught wind of them. That was why the forty or so people had taken flight after meeting the bandits earlier.
But Happy was different.
