After addressing Number Thirteen, Gao Yang waved his hand and quickly ran downwards, returning to Li Yunzhe's side, and gestured to others that the second floor had been cleared before urgently saying: "See where support is needed and go quickly."
Red Feather was hindered in his movements, as he had a huge wound on his leg, so Red Feather sat on the ground, using a tourniquet to bind his leg to slow the bleeding.
Gao Yang had emergency medical supplies on him, of course, just a personal first aid kit.
For people like Gao Yang, having some basic first aid knowledge was a given. Although there were medics, there were situations where medics weren't nearby, and self-aid was essential. Not to mention, being able to stop one's own bleeding was beneficial, so having a personal first aid kit was definitely necessary.
What Gao Yang could do was to temporarily stop the bleeding with a tourniquet; he was powerless to help with Li Yunzhe's injury.
