Ye Chen continued to improve.
At this moment, a black mist suddenly shot out from Ye Chen's body.
This black mist continuously churned and turned into a gigantic black demonic mouth in the air, viciously biting toward Ye Chen!
This huge black Demon's mouth carried a sinister aura.
Ye Chen raised his head and looked at the ferocious black Demon's mouth.
The black Demon's mouth was only about ten meters away from Ye Chen.
The huge black mist gathered in the air.
Both of them were extremely shocked.
"Little junior brother, this is..."
Ye Chen looked at the black mist in shock, and his heart was extremely shocked.
He quickly looked at his Dantian.
In his Dantian, the Yin-yang diagram that he had cultivated previously was now completely covered in black mist. The Demonic Qi had already covered his dantian.
Even the entire True Qi sea was filled with Demonic Qi.
