The skeleton's weakness
The skeleton summoner had already gauged the strength of each human present in its chamber and knew that all of them were weaker than itself in terms of cultivation, including Xie Yang.
"Attack them and kill all except for him!"
The skeleton monster spewed out as he waved its scythe before pointing it at Xie Yang.
The meaning of his words was quite clear.
It wanted everyone except for Xie Yang's death.
As for why?
Even that was pretty clear.
It wanted to toy with Xie Yang and torture him to death!
All of its anger had turned on him!
The skeletons that it summoned charged towards Xie Yang and the others as with a loud booming noise, the huge gate behind them closed shut tightly.
It had cut off their only path to escape from this place.
It left them with no choice but to fight.
