The swarm of flies blotted out the sky and sun.
Wei Yuan sat in his chair, holding a cup in one hand, sipping tea that didn't actually exist, while using the other hand to grab a fly that had penetrated the room and casually tossed it into the Dao Foundation after trapping it in a bell.
As one fly perished, another would take its place, yet upon entering the room, each would instantly become dull and sluggish. Sometimes, Wei Yuan would stretch and not bother with them, and they would just fall to the floor, limbs twitching, unable to move.
On the table stood a small five-story tower radiating invisible oscillations. Including the two on the windowsill, there were three Suppressing Mortal Towers in the small space. The Ghostly Fly Group wasn't of high grade, and with the three towers suppressing them, they naturally couldn't move an inch.
