The lieutenant colonel didn't know that the drone also had the capability to catch Yan Fei in mid-air, which was exactly why she kept chasing him closely, not wanting to let the distance between them grow. Otherwise, she would surely have been attacked by the drone. Despite being hit by the 30mm aircraft cannon shells, the lieutenant colonel's immense strength meant that the shells didn't harm her at all. Moreover, she cleverly used the propulsive force from the explosions behind her to suddenly accelerate and close the gap to Yan Fei's physical self.
