At the banquet, Wang Linchi blended into the crowd of ghosts with an expressionless face. He had changed his aura and vibrations to resemble a wandering ghost. The Wanderers, on the other hand, managed to fully transform themselves into ghosts using Ghost Patterns, becoming indistinguishable from real ghosts, except that their core was still human. Chen Wen transformed into a Food Law Ghost and was indistinguishable in both appearance and aura. If Wang Linchi hadn't personally witnessed the transformation, he would have mistaken Chen Wen for a real Food Law Ghost.
