This ancient human looked down on him because he despised his combat power.
Han Fei didn't need him to take his combat power seriously. Anyway, it was impossible for him to exchange souls with him. Since the other party wanted his body, he wouldn't destroy it.
Therefore, he could fight freely.
Even if he couldn't beat him… Han Fei was waiting for the moment when he was defeated. The last thing he was afraid of in this life was to be possessed. The Demon Purification Pot had already exceeded the level of the Sea Realm, which was even scrambled for by the gods. It would be a joke if he couldn't even take down the soul of an ancient human.
The man was not afraid of Han Fei running, because he had seen through Han Fei's limit. Running was a dead end, but if he stayed, there would still be a chance of survival, so he wouldn't run.
