Yan Fei recognized the Lieutenant Colonel's identity through the characteristics of the Universal Qi Lock, but the Lieutenant Colonel did not know who the enemy ambushing him was. This was mainly because Yan Fei's strength had increased too much compared to before, and he was completely different from the Yan Fei in the Lieutenant Colonel's memory. At the same time, Yan Fei was entirely wrapped in a black diving suit, without exposing any facial features, so the Lieutenant Colonel failed to recognize that the person ambushing her was the very Yan Fei she had always wanted to deal with.
