At the critical moment, it was Lan Xue who fired the gun to rescue Luo Zheng. When the enemy appeared, Lan Xue had already spotted him. The reason she didn't shoot immediately was that the enemy deliberately exposed himself. A sniper would not easily expose their body unless necessary; thus, Lan Xue was also waiting, until a killing intent burst from the enemy and she preemptively struck with a headshot. Lan Xue was fully confident in her abilities.
After killing the enemy with one shot, Lan Xue did not reveal herself immediately; instead, she continued to wait and observe her surroundings to prevent any accomplices from appearing. Seeing Luo Zheng quickly take cover and scan for suspicious targets instead of running around like a new recruit, she smiled, satisfied with the great improvement in his psychological quality.
