There was a reason why the Demon Vanquishing Tree didn't attack the blood spring. If he wasn't careful, he would be contaminated. And once he was contaminated, it would be over. Once he fell, the entire Puppet City would fall.
Therefore, the Demon Vanquishing Tree could kill the Bloody Hand Mine Devils because they contained little ominous power, so there was no pressure to purify them.
However, the blood spring was filled with the ominous aura and the suppressing pressure of the Great Monarch Bloody Hand. Thousands of Bloody Hand Mine Devils were guarding there like devout believers for the ominous aura.
At this moment, the Demon Vanquishing Tree had agreed to part of Han Fei's request, so he began to attack. The Bloody Hand Mine Devils that were trying to break through the barrier of Puppet City suddenly encountered overwhelming green jade vines.
For a time, Flash, Killing Fists, and Bloody Claw filled this space.
