"But if it was cranial trauma, then Guan Liu should have died."
"His martial arts skills are very high, so he was able to survive. Given enough time, he could even heal himself and fully regain consciousness."
"We can't let him heal by himself, cough. I mean, we can't let him self-heal in the captain's perception, we must be the ones to cure him."

"But the problem is... there is no such medicine. Surgery is required, as well as neurological rehabilitation and hyperbaric oxygen therapy."
"Do we need to teach the captain to perform the corresponding surgery?"
