Thanks to the wonder of The Infinite Ever-changing World Technique, he didn't have to worry about being detected by radar systems in various countries during his flight. The distance from Germany to England wasn't too far in the end. It was only when the skill of the Golden-winged Roc flying to 90,000 li was fully unleashed, did Qi Yue come to appreciate its magic for the first time.
Flying to 90,000 li was indeed very fast for short distances, but, its speed advantage fully came into play when making long-distance flights. With the increase in flying distance, the speed-boosting ability of Flying to 90,000 li was pushed to its limit. It took Qi Yue less than two hours to fly from Germany to London. During this time, Dracula Castle was mostly resisting the attack of The Church with the help of its own domain. Therefore, Qi Yue managed to rush back in time.
