The first possibility is that the other party hasn't discovered the Wangzai Little Buns conducting the island exploration.
They only found those high-tier players who entered later to investigate.
So they took action to easily deal with those high-tier players.
This possibility would lead the other party to assume these players were sent by an advanced Necromancer.
In that case, they naturally wouldn't be afraid.
The second possibility, however, is that they discovered Wangzai Little Buns who were conducting the investigation.
But because Wangzai Little Buns didn't enter the island at that time, initially, they might have thought Wangzai Little Buns were just passing by.
But after the players entered the island, they must have sensed something was amiss and connected the two things.
