Xia Fei kept his speed at 100 m/s, maintaining a steady pace as he leaned his body forward about 10 degrees, keeping his center of gravity a bit forward. This posture was the most suitable for long-distance running, as it significantly reduced the amount of energy needed to keep running.
The rain shadow area was vast, and due to the aridity over time, the yellow earth beneath his feet had cracked into pieces, and there was even a layer of yellow sand accumulated on it.
A series of yellow sand clouds and footprints were left behind as Xia Fei ran through at high speed. Fortunately, the rain shadows were windy all year round, and the dust and dirt that got swept would quickly cover up his trail, leaving no traces behind.
