Chen Fei took Tanya back to his homeland by the most convenient method — taking an international public flight where you could just sleep through and arrive at your destination.
If they traveled by land, even if the Mobile Base Vehicle traveled day and night, it would take at least a week to reach the border, and it would roughly take the same amount of time by train.
However, Adrian hoped that when Chen Fei and Tanya left, they could employ a strategy of drawing attention away from the main action, facilitating the rest of Team 04 to infiltrate and find ways to penetrate into the key industries of Yarsk City, the capital of Tunguska Region.
Indeed, leaving the Mobile Base Vehicle behind was of no use; lacking Chen Fei, the major humanoid battery and the remote control of artificial intelligence AI "Adam," it could only be used as a fixed fortress with very limited endurance, and charging it was not convenient either.
