At this point, Li Fei paused before he suddenly turned to his apprentice, Song Qingfeng, and asked, "Old Song, can someone who acts like this even be called a doctor?"
Song Qingfeng also despised Gongsun Mo to the very core, especially since he had realized that Gongsun Mo was using such a young girl as a test subject, which instigated an intense loathing. Although he had sought some test subjects himself, they were volunteers, and many people bought his youth-preserving pills out of greed, hoping to recapture their youth.
In a sense, one could say it was the pot calling the kettle black, but Song Qingfeng still reassured himself at the bottom of his heart that he was not that kind of person. Some things could be done, and some things couldn't—if that was the logic, then there was no problem with the revulsion he felt towards Gongsun Mo.
