Ye Feng took the initiative to offer help.
Because by helping the Black Prison Demonic Beast, he was actually helping himself too. After all, collecting the Evil Thought Fruit required hunting down criminals, and during this process, he could absorb some of the energy to enhance himself.
Therefore, Ye Feng decided to act.
Benefiting both others and himself; mutual advantage.
"Roar!"
Upon hearing Ye Feng willing to help, the Black Prison Demonic Beast was deeply moved and opened its mouth to spit out a crescent-shaped sharp white tooth.
"Is this... a weapon?"
Ye Feng caught the beast tooth and felt the fierce aura within it. If erupted instantaneously, it could even kill a Ninety-five Layer Immortal Emperor.
The only downside is that it can only be used once.
For Ye Feng, who owned the Myriad Spirits Treasure Vase, the tooth wasn't of much significance.
Yet, Ye Feng still expressed his gratitude.
