After fusing, Zhou Wen arrived behind Pixiu. His Eyes of Penetration activated, allowing him to see through Pixiu's body.
The Golden Overlord Sword had already been melted and absorbed by Pixiu, making Zhou Wen's heart ache. Such a divine weapon had been destroyed by it.
The gold, silver, and copper ore that it had devoured had mostly melted. Thankfully, Zhou Wen saw that the Chaos Bead hadn't been melted and absorbed. The bracelet was gone, leaving only a bead.
Thankfully, the Chaos Bead is still here. Zhou Wen took the opportunity to use Doctor Darkness's Wheel of Destiny while Pixiu and Tyrant Behemoth were fighting.
Darkness Right Hand was activated as Zhou Wen's right hand reached into the back of Pixiu's head and stirred it, tearing a huge chunk of its brain apart.
As it was too big, Darkness Right Hand couldn't pluck out its entire brain. It could only do its best to cause damage.
