They were racing against Ye Feng, but Ye Feng was racing against time. The sooner he escaped, the safer he would be. So, Ye Feng was racing against the clock, trying to escape in the shortest time possible.
Although Ye Feng was an Ancient Martial Artist, this escape was still quite taxing on his physical strength. The high intensity and prolonged escape increased the energy consumption for him.
After a while, Ye Feng began to feel a bit fatigued. Feeling as though he could hardly hold on, Ye Feng quickly retrieved a vitality-restoring fruit from the Chaotic Space, replenishing his energy while on the run.
This action provided some help to Ye Feng, but not much. It took eating several fruits before his state improved a bit.
But it wasn't enough. After running for a while, Ye Feng felt exhausted again, and this time the fatigue was even more severe.
