Lexington's arrangements quickly bore fruit!
Following his orders, the troops from Chenxiu City launched an attack on Thunderhawk City soon after their assembly. Although the attack ended in a bitter defeat, it achieved Lexington's strategic goal, which was to slow down Thunderhawk City's advance toward the border as much as possible.
After the battle, Rocky won, but the advance of Thunderhawk City significantly slowed down. This not only allowed Lexington, who was following closely, to shorten the distance but more importantly, it allowed the other three Sky Cities to gain a lead in speed, almost guaranteeing that they would arrive at the border first.
Consequently, Rocky was entirely put on the defensive.
