Pierce did not know why the monster was so weak this time!
Pierce felt like the invasion this time was like a buffer period for the participants in preparation for more difficult invasions. Since the monsters were quite weak on his side, the other participants were definitely facing weaker ones.
However, he did not have enough evidence to prove his guess, but this was none of his business anyway. It was all easy for him.
Perhaps it would become truly difficult at the tenth invasion or above. He felt that even the true gods might appear during those invasions in his hell mode difficulty.
He had to increase his strength before that. Otherwise, he would be eliminated by this Tower Defense world.
The attacks from the elemental arrow towers were very fast. In just half an hour, the monsters hiding in the clouds were all annihilated, leaving only broken limbs and remains floating in the air which were also falling down.
