Yan Feng was extremely tense at this moment, watching the streams of black aura emerge from the hunted demonic beasts. He couldn't help but curse inwardly!
He had long known that bringing people to Demon Heart Island for training wouldn't be easy, but he hadn't expected to encounter the black aura, those Evil Thoughts, so quickly.
The things released by the Evil Spirit Universe are not good, and if people get contaminated, they might meet their end right away.
"Take out the Tranquility Pills; everyone takes one!"
Fortunately, the High Priest of Demon Heart had previously reminded him to have the Family Heads prepare Tranquility Pills for their heirs.
Even those Family Heads who had complaints about their heirs were warned by him and Mo Aotian when they visited, forcing them to prepare Tranquility Pills.
Finally, those were put to good use now.
