These bird puppets are similar to the ones distributed to the rest of the people.
However, these are of higher hardware, quality and configurations. They are made to build and repair other things. The moment the turret was destroyed, the birds flew there and started repair it at a visible pace.
Within three seconds the turret was reinstalled.
As for the self-regeneration of the equipment? It still works, but it is way too slow to use in such a heated moment.
The attacks resumed and the cavalry was bombarded. When one of the centaurs hit the bird puppets out of frustration, the puppets' bodies collapsed and a small rock was launched out of those collapsed bodies.
It had a homing function and it was locked on the attacker who did it.
At that moment, it destroyed itself with an explosion similar to the destabilization of a Divine Plane cultivator's whole Divine Plane energy.
*BOOM*
