Fighting directly on the sky aircraft was not as simple as he had imagined.
Of course, Xu Tui had also considered this problem when he drove the repulsive-force flying car back to Jincheng Prefecture to fetch his parents. He only had such confidence now.
For example, the parallel speed of the flying sword and the sky aircraft. The relative speed of the sky aircraft and the enemy. The flying direction. The instantaneous distance and the variable distance.
Xu Tui's flying sword would have been able to fly out of the sky very quickly since the sky aircraft's speed was so fast. However, he would instantly lose contact with the flying sword as the distance between them widened. Especially in the opposite direction, the flying sword instantly lost contact with his mind power.
