Although the Death Scorpions couldn't harm the Death Gorillas, Du You still noticed a problem. The attacks of the Death Scorpions didn't penetrate the Death Gorillas' bodies, but they did ooze some extremely potent toxins. Over time, these toxins began to accumulate.
Some of the Death Scorpions even directly initiated a Death Raid, to no avail in breaking the defense—the disparity was simply too vast. The Death Scorpions here were at most of the second tier and with an inability to breach defenses, the ones to die could only be themselves.
However, the lingering toxins didn't vanish; they continued to erode the Death Gorillas.
As time went by, more and more Death Scorpions appeared, but the aura of the Death Gorillas kept declining. It was the first time Du You had seen a tactic that could kill his own Death Gorillas without needing to breach their defense.
