The special material of the Devouring Sky Clan Fortress can counteract the attacks of Chaos Creatures, but this counteraction has limits. When the attack power reaches a certain extent, the Devouring Sky Clan Fortress will suffer substantial damage.
Ordinary Title Controllers can exert attack power that exceeds the defensive limits of the Devouring Sky Clan Fortress. In fact, even a Controller at the level of Chenyuan Emperor can somewhat affect the Devouring Sky Clan Fortress, though the effect is minimal. If Controllers at the Chenyuan Emperor level were to attack the Devouring Sky Clan Fortress, it would likely require hundreds or even hundreds of them to attack simultaneously for a long time to destroy the fortress.
At this moment, Jing Yan casually swung his sword, causing cracks to appear across some areas on the surface of the Devouring Sky Clan Fortress.
"Not bad!"
