There was too much coincidence.
Why would Tu Wenheng suddenly appear in front of them?
Moreover, Tu Wenheng had already killed all the swamp magical beasts here before they arrived. At the same time, he was already familiar with this place.
It had to be known that in such a dense illusory fog, perception and the naked eye were limited. At the same time, it was very easy to lose direction without any reference.
Tu Wenheng was so familiar with it, which meant that he had been exploring here for a long time.
Moreover, if he knew that the Illusion Core was so powerful, why did he look for others and even cultivators weaker than him to cooperate?
Could it be that it was really as Tu Wenheng had said? Was it because his methods could not do anything to this Illusion Core?
It was impossible for Mu Fusheng to believe them with so many suspicious points in front of him.
