Dingxing and the others looked at the ruins with an ugly expression. When Jieyu and the others left, the base was still fine. However, they had only been away from the base for a few hours.
In just a few hours, a base guarded by a God-level warrior, which they thought was unbreakable, was destroyed by someone. Everyone in the base disappeared. From the undead creature they saw just now, they knew clearly that everyone in the base had gone there.
That was the reason why they looked so upset. It wasn't only because their base had been destroyed, but also because Zhao Hai had grown stronger.
There were nearly a hundred million soldiers guarding the base. If Zhao Hai turned them all into undead creatures, the number of undead in Zhao Hai's Army would increase again, making him even more difficult to deal with.
