Medical Officer Tong was terrified, knowing that you use this thing to prick people, but there's no need to do it for the living!
There's no liquid medicine!
However, the next second, a stream of gas leaked out from the other end of the needle, and Medical Officer Tong saw the patient's swollen chest slowly collapse.
To say it collapsed isn't quite right, it's more appropriate to say it returned to normal.
After that, the patient's previously very difficult breathing also became smooth.
Medical Officer Tong found it hard to believe, he had encountered this condition while practicing medicine at the frontier; some were caused by injuries, while others arose spontaneously. None of the doctors at the frontier had a solution, they could only watch the patient wait for death.
So... just pricking with a needle would do?
