The area around Sunrise City is all plains. Escaping the city with hostages, although difficult, was still a possibility. This had been assessed before the departure at the meeting in Shrek Academy Sea God's Pavilion. The most troublesome part was how to get away after breaking out. On the vast expanse of plains, escape would not be easy. Especially when the hostages had all suffered some degree of injury, it was definitely unscientific to run for a long time.
Therefore, Shrek Academy made a bold and costly decision.
If one wanted to quickly lose the enemy on the plains, there was only one way—speed!
Only with astonishing speed could they lose the pursuers in the shortest time possible. How could the hostages increase their speed? With flying soul devices!
