At 9:40 AM, Yan Feifan performed a dehydration and shrinkage test using anhydrous ethanol on the brain tumor tissue obtained from the patient via a puncture biopsy.
Shortly before 11:00 AM, after receiving the test results, Yan Feifan performed a puncture injection on the patient's cranial tumor with Qin Feng's assistance.
Although Yan Feifan had been reluctant to take on this surgery, he hadn't cut any corners in his preparations.
After all, the patient sent over to be a guinea pig had done nothing wrong.
Besides, it was Yan Feifan's principle to always give his all, treating every patient with one hundred percent preparation and effort.
That said, Yan Feifan had a rather good impression of this "guinea pig" patient.
This was despite the man being under anesthesia the entire time, never having exchanged a single word with Yan Feifan.
The man was forty-three years old, with a square face and a broad forehead.
