All around them were monsters, and even the air was occupied by flying monsters.
This kind of monster attack was really terrifying.
Ren Qi's expression also became serious. He did not expect the second attack of the monsters to be so huge.
The good news was that most of these monsters were Tier 3, and they were not very strong.
However, the monsters in the air were all Tier-4 flying monsters. Although they had been moving behind, they were extremely fast and took the lead to attack Ren Qi's territory.
Ren Qi waved his arms, and the four Tier-4 defense towers that stood at the four corners of the territory started firing cannons.
The cannonballs bloomed in the air and exploded in the midst of the flying monsters that were attacking Ren Qi's territory, forming a bloody mist.
At the same time, the succubi on the wall also launched their attacks. A large number of fallen flames shot out toward the flying monsters in the air.
