"It seems I really underestimated this Fat Cicada." Ye Shikai quipped. This time, the Poisonous Insect King saved him, which also served as a reminder. Since these black-robed people can use worms as hidden weapons, it indicates that they know how to cultivate and use worms. Hence, these black-robed people are very likely the 'owners' of this cave, and that towering tree might be the 'hotbed' for cultivating worms.
Logically speaking, they are outsiders, and it seems unreasonable to just kill an 'owner' like this. But there's no other choice; this person didn't say anything and attacked with lethal intent. Ye Shikai could only eliminate him first, otherwise, he would be the one to die.
