Why does Fei Da have a bad personality?

Fei Da has a bad personality for several reasons:

1, using others to achieve their own goals. Fei Da's original intention of accepting Su Rong was to cultivate immortality with the help of Su Rong's beauty and ability, which made Fei Da appear indifferent. The concern for Su Rong is more like an instrumental figure.

2. The words are too straightforward. Fei Da's personality is straightforward, and his speech is unadorned, which makes Su Rong and others feel rude from the beginning, giving people a sense of inhumanity. It is really straightforward, but it lacks polishing and consideration.

3. Be too strict with Su Rong. In the process of training Su Rong, Fei Da's tone and requirements are harsh, which makes Su Rong feel that Fei Da doesn't care about feelings and makes the audience feel unsympathetic. Severity also needs moderation, otherwise it will appear bad character.
