He Shancun was just biting into a zongzi when he heard Zhou Ning ask such a question, clearly taken aback.
Chewing the zongzi, He Shancun also mulled over the meaning of Zhou Ning's words. After a moment, he slowly said,
"Actually, Xu Qingquan's head injury was not severe, unlike the driver Qiu Chunbo, who had a skull fracture and intracranial hemorrhage, along with hematoma compression. For him to be able to recover his speech system was quite fortunate. His memory of that night is very fuzzy, which I feel is related to his fatigue. During a moment of inattention, the accident happened.
As for Xu Qingquan, his symptoms were mild; he only experienced nausea and vomiting once on the day he was admitted for surgery. The intracranial pressure increase triggered by vitamin A was quickly brought under control. In theory, his amnesia shouldn't be the most serious, but sometimes medical science can't explain things.
