Invading spirit

'They're going to be slaughtered at this rate.' The spirit orc thought in frustration, realizing that despite the demihumans' best efforts, they had already lost thousands and even more were wounded, while their enemies still hadn't lost a single soldier.

As if to force the spirits not to interfere, the acid rain increased in intensity again and now the spirits barely had leeway to pay attention to the fight.

The entire barrier was being eroded away and it required the undead's concerted effort to prevent the ton of acid above their heads from destroying the entire forest. The acid dissolved after a while, eroding the barrier, but more was being poured out by the wasps every second.

He noted that despite the demi-humans quickly getting back on their feet and fighting back, the black barrier would not break so easily without the orcs, the greatest damage dealers among the demi-humans.
