They only felt a numbness at a certain acupoint on their bodies, and they immediately tapped on this acupoint to prevent the spread of the poison!
"Damn it, Old Monster Du, laying poison on us, you old immortal!"
At this moment, not only was Old Monster Ye cursing, but the other two old masters were cursing as well, though their curses were in the language of the belly, as the poison continued to spread within the barrier they had created.
They didn't stop fighting, but Old Monster Du kept releasing poison, and the toxic gas couldn't disperse into the air within the barrier, and Odd Tang kept releasing poison, not just one kind.
As a result, many different poisons combined to become an even more complex poison, which began to mutate and grow more potent.
The other three old masters knew the severity of the situation and took Detoxification Pills, but they still felt the poison's strength was too overpowering; they held their breath and their bodies went into defense mode.
