Ye Fan agreed to Chu Biyao's request; as long as he wouldn't be exposed on the screen, he naturally wouldn't refuse to help Chu Biyao.
Regarding the invitation from this unreasonable woman, Lu Xiangxiang, Ye Fan naturally didn't care. He remained indifferent to matters in the medical world. Even if he had the mind to teach others his medical skills, no one dared or could learn them.
The other name for the Divine Acupoint Ghost Doctor is no different from the Life-taking Ghost Doctor. When mastering the art of acupoints initially, it relied on human lives for practice. To accurately master this technique, who knows how many lives are needed as sacrifices.
Therefore, in terms of medical skills, it's not that Ye Fan is hoarding knowledge; it's just that the Divine Acupoint Ghost Doctor is too bizarre. With its every move endangering lives, exposing it to the public serves no good; besides possibly leaking his identity, others cannot learn this acupoint technique.
