Luo Ziling looked at Falcon's severely damaged arm wound, then cut opne his pants with scissors to carefully examine the injury. After that, he turned to Lin Lan and said, "I can't guarantee anything, but I will do my best to treat him."
Luo Ziling further understood why Lin Lan and Falcon had come to seek his treatment instead of returning to the base or going to the hospital.
Whether they went back to the base for military medical treatment or to a hospital, it wouldn't be possible for the function of the hand and leg to fully recover, because the kind of treatment employed there wouldn't allow the nerves and muscles to completely heal from the damage.
Last time, Lin Lan's gunshot wound wouldn't have fully recovered either if it were treated with standard hospital procedures; there definitely would have been lingering effects.
