Three hours later.
A shadow darted quickly out of the dormitory building, running to the base of a large tree and removing a mask.
"Yue," he dry-heaved.
Behind him, Xu Yun and Director Guan, among others, also walked out of the dormitory building with tired faces.
Three hours earlier, upon arriving at the 'scene of the incident,' Xu Yun and the others immediately started the cleanup work.
Compared to the complex and numerous scenes, their method of cleanup was actually quite simple:
The campus's agricultural institute provided a large vacuum cleaner, which was reportedly developed to clean up locust corpses and could inhale large objects.
Xu Yun and the team retained the front suction port, while the latter part containing the storage box was modified into easily detachable burlap sacks.
One person held the front, while another blocked the sack, directly sucking up the roach corpses from the ground.
