When Wales saw those horrendous mini-missiles fall on the same ship and Luo Yue's jets fly across the sky, he knew that Luo Yue was forcing them to surrender. If they didn't, then they wouldn't be just showing off anymore - those locust missiles would swarm them once again.

Hence, Wales surrendered.

When he saw the thousands of fighter jets fly over Luo Yue, he was confident that they would soon come to give him support. However, reality was harsh.
Before those fighter jets even came to Luo Yue, they were taken care of by the dense swarm of mini-missiles and were all struck down.
