After Old Teng entered the black barrier, the thunderous booms inside became even more relentless.
Even standing outside, Wu Shaozhen felt his heart pound with fear.
Unfortunately, there was nothing he could do. With his strength, no number of survival skills would keep him alive if he went in. He could only trust Zi You and Old Teng.
Suddenly, as though he had remembered something, Wu Shaozhen activated Illusionary Wings and flew back the way he had come.
He soon returned to their previous location, where the two Immortal Beasts were still locked in a fierce battle.
"Damn it, I can't handle a Saint-tier enemy, so I'll have to pick on an Immortal-tier one!"
Once he got closer, however, he discovered that the Nether Behemoth, which had only had 40% health left, had recovered to 60%.
"For fuck's sake, you've been fighting all this time and accomplished nothing!" Wu Shaozhen complained to the Plunderer.
There was nothing to be done about it, though. As expected of a creature connected to the Nether Clan, the Nether Behemoth had insanely powerful healing. Without Wu Shaozhen's poison, the Plunderer really couldn't do anything to it.
Wu Shaozhen rushed in, applied full poison stacks with a Shadow Sevenfold Strike, then immediately retreated.
It wasn't that he didn't want to deal more damage. Those two routinely dealt hundreds of thousands or even over a million damage. His paltry damage wasn't even worth mentioning, so he was better off just applying poison.
As soon as Wu Shaozhen's poison took effect, the Nether Behemoth's Recovery skill stopped working, and its health finally began plummeting again.
The Plunderer still had over ten minutes left, more than enough time to kill the Nether Behemoth.
Before long, the Nether Behemoth's health dropped into execution range. Wu Shaozhen detonated Evil Mark
