In the eyes of the warriors, Zhou Zheng was a madman. The reason he dared to challenge the Sixth Tier Mutant Viper was because he himself believed in the madness of the Apocalypse Rogue...

But to reach a higher level and break through again, one must undergo such life-and-death trials like the Apocalypse Rogue.

Just a small drop is enough to kill a strong Fifth Tier bull in a matter of minutes.

Zhou Zheng's greatest reliance was the antidote in his backpack.
