It might sound complicated, but it wasn't too difficult to deduce the series of events after learning of the other party's identity.
While Zhang Xuan was in the midst of conversing with the Violetleaf King, Poison Master Bai's Primordial Spirit returned to his body before walking up to the Earthleaf King. With a tap of his finger, a unique poison seeped into the other party's body.
After which, with a wintry face that was devoid of the slightest warmth, he bellowed, "Who sent you here?"
"This is bad!"
Seeing Poison Master Bai forcefully interrogating the Earthleaf King, Zhang Xuan's face immediately warped in horror, and he hurriedly rushed forward to stop the other party. However, it was already too late. The trapped Earthleaf King forcefully clamped his jaws together, and his face immediately turned extremely red.
