Xiao Mu pondered upon hearing this.
A third-class evil zombie was indeed quite strong. With Zhao Yan and Wang Tong in the early stage, and himself, and the ghost servant in the middle stage, they wouldn't have much problem against it. Even with the right setup, killing it wouldn't be difficult.
However, what worried him was the possibility of other evil zombies.
Iron corpses or ordinary zombies weren't worth mentioning. Even a dozen of them wouldn't make much difference. What really mattered were other evil zombies.
An ordinary first-class evil zombie might not be an issue, but if an additional second-class evil zombie were present, it might get dangerous, let alone another third-class evil zombie. Xiao Mu would simply run away in that situation.
After all, evil zombies were slightly stronger than Blood Demons, and a third-class evil zombie was even more powerful than a red Blood Demon.
