Yan Fei's operation had several objectives, including obtaining the Upgrade Essential Items for Drones, destroying the supercomputer of Future Technology, annihilating the Artificial Intelligence "Future", and wiping out Future Technology's Smart Manufacturing Factory and the Terminal Illness Hospital.
The most important goal was to acquire the Upgrade Essential Items for Drones. Hence, until those were secured, Yan Fei would refrain from any other actions to avoid alerting the enemy and losing the trail of the long-sought Upgrade Essential Items. Upon successful entry into the Underground Military Fortress, Yan Fei's direction was set towards the Dean's Office.
