3 Party Invasion.

This sound attack produced by the sound blaster is a weakened version of the scream that dominated the battlefield when the plane was invaded by the Supreme beasts. However, each sound blaster is an Origin weapon and there are thousands of them, not just one. So they have the advantage of quantity if not quality. 

By the Mechanical Emperor's estimate, the sound attacks should be more than enough to inconvenience the Origin god Stellos and prevent them from shearing through the robots easily with their Origin diamond divine ability the way the Shadow of Despair tore through his enemies.

With these arrangements done, the Invigilator and the observers focused on the Shadow prowler in the Shadow of Despair's base. She is the highest priority and they don't want to be distracted from her. But their attention was finally taken away when they heard another alarm.
