The system started summoning large numbers of skeletons, liches, and dragons near that gate.
They were previously prepared for the mission, so once they appeared they moved towards the nearby gate without hesitation.
The dragons acted as general commanders with the help of many liches as their aides to direct all the skeletons towards the gate.
The battle on the doorsteps of this gate was really difficult, especially the gate didn't stop sending out massive numbers of demons. Ibro didn't want to delay further, so he moved towards that gate.
Once he reached above it, he used on strike to eliminate all the demons standing between his skeletons and the gate. This window that he created allowed the skeletons to reach the gate and started entering it.
In the beginning, some demons still came out from the gate, but they were rapidly killed by the skeletons. After nearly ten minutes, no new demons appeared from the gate anymore.
