Pei Xu had been paying attention to Shen Xi's movements. Since she came in, her face was cold with no other expression, but there was a slight change at that moment, which panicked him.
When Shen Xi first told him that she had medical knowledge, Pei Xu did not have the slightest doubt. That racing accident last time had him in complete admiration of Shen Xi, so even if she told him that she was a goddess, he would believe her.
Shen Xi's gaze changed slightly.
Ning Sinian was not a normal patient in a coma. He was poisoned. It was caused by a neurotoxin that invaded his brain and numbed his senses so he would seem to be in a vegetative state.
Perhaps in the first few months of Ning Sinian's accident, he was indeed in a deep coma, but this toxin was the culprit that made him into the current state.
