Professor Chen's expression took everyone by surprise, and Doctor Huang was the most astonished of them all.
Not only because he had known Professor Chen for many years, but also because in his impression, Professor Chen was not only skilled in medicine and knowledgeable, but he also possessed a strong heart.
In the years of working with Professor Chen, no matter how serious the patient was, he had never seen Professor Chen display any panic.
Professor Chen always seemed calm and composed, as if everything was under his control.
Even when treating someone as important as Elder Liu, he could remain relaxed and calm, as if Elder Liu was just an ordinary patient in his eyes, without showing the slightest bit of tension or fear.
Therefore, this was the first time Doctor Huang had seen Professor Chen so excited, and it was precisely because of this that he was extremely surprised and also very interested in the Daozang Secret Technique mentioned by Professor Chen.
