Two-Faced

Li Haotao first briefly explained the anatomical structure before proceeding to angiographic images of the prostate.

It was valuable information.

Barely anyone got to perform an angiography of an organ and save its images if the patient did not undergo that organ's specific surgery. 

However, the research institute actually owned such records. Zheng Ren watched the slideshow attentively and assumed the information came from the private repositories of multiple professors.

They were actually angiographic images of bladder and renal tumors, but some of the contrast agent had entered the prostate or its surrounding tissue, so they had saved these images to provide a theoretical basis for this research project.

Li Haitao merely stated facts without the domineering tone of a lecturer, which eased the atmosphere.
