In a dark cave, there wasn't a trace of light, and underfoot was a sticky substance like crusted snot that made squelching noises with each step.
The air was filled with a sour and strange odor.
However, for Tao Yu, this was hardly an issue, as the pitch-black cave did not affect his vision.
It was only upon seeing two aliens on the ground with their acidic blood splattered all over from being blasted that Tao Yu couldn't help but feel speechless.
"Next time, I should get some paint to mark the aliens, to easily identify them…"
With a locator, Tao Yu finding the alien nest was only to be expected.
With the help of temporary recruits, the narrow confines didn't give the aliens any chance to rush at them.
It wasn't until the interior of the alien nest sensed something wrong and increased their reconnaissance that the cannon fodder aliens began to suffer casualties.
