Kai doesn't have any intention to take another adventurer from this City. Why? First of all, betrayal could happen.
If he was all alone, he would not mind it. However, he was with Alexa, if something came up other adventurers could use her as a hostage.
So in order to continue the expedition inside the portal, he decided to have a duel with Henry. To achieve that, he used the provocation that appeared on the screen after casting the [Peak] skill.
To begin with, Kai and Henry were standing on the vast platform made from polished marble. Around them, were the two practitioners, Alexa, and the mana plate. It appeared that this place was used for the evaluation so that the other adventurers were clueless about each other's rank.
"Don't blame me if there's something happens to you here. Remember, you are the one who insisted on this fight." Henry warned him in an annoyed tone as he thought this man was taking him as an ordinary practitioner.
