After learning the professional skills, you need to practice to perfection through your own efforts (Baidu Search 178 Herb Picking or 178 Herb Raiders, the word "herb" can be replaced), and then you can find the additional skills (general (basic) skills) of the acquisition department in your skill book, and the manufacturing department in the professional column of the skill book. You need to see the details in the game, and the skill position should be fine.
