This skill is not an important skill. If the auxiliary skills (such as cooking and medicine refining) are high, you can be appropriate and don't need to ask others. As far as your situation is concerned, I suggest not to worry. With the help of tributes, you can order as much as you can, and there is no need to hurry, because when you are in a hurry to use T, you can just buy a centenarian, and the effect is not very good at ordinary times.
