When Jin Xin heard what Nuanyu had said, he felt not only a chill in his heart, but also a sense of incredulity.
The chill came from the fact that he, too, had been afflicted with Gu poison—a poison against which medicine was utterly helpless. It seemed that if Nuanyu didn't help cure the Gu poison, he would undoubtedly die.
Although he was a modern man, what was modern than him was—he was clearly discernible that today's medicine could only treat ten percent of known diseases at most.
Perhaps this was even an overestimate.
A common cold could be improved within seven days with an IV drip, and with plenty of rest and water without doing anything, it would also essentially improve within a week.
What role did medical treatment actually play in this? Perhaps just the medical record they wrote could help you take a few days off work to drink water?
