The Eyes of the Holy Doctor can directly see through a person's internal illnesses with their eyes.
In their entire country practicing Eastern Medicine, only his Master, the First Person to practice Eastern Medicine, Jin Yuan, had opened the "Eyes of the Holy Doctor".
And in their country, those who had opened the Eyes of the Holy Doctor could be called "Medical Sage".
"Eyes of the Holy Doctor?" Lin Dong heard this, and he was somewhat puzzled, "What are the Eyes of the Holy Doctor?"
"Surely! You don't even know what the Eyes of the Holy Doctor are, how could you possibly open the Eyes of the Holy Doctor. Indeed, I thought too highly of you, you must be spouting nonsense!"
"You said you diagnosed his illness, then write it down, let's see if your diagnosis is correct!"
Lin Dong couldn't be bothered to waste more words with him.
He directly went to the table, took out paper and pen, and wrote down his diagnosis of that person.
"Brain tumor!"
