Auxiliary skills can only be learned in gangs, and the old demon in the border area of Montenegro can only learn 40. If you only help yourself, the first auxiliary skill of any sect must be to strengthen the body (the upper limit of adding blood to yourself). If it is not DT, then meditation is the second auxiliary skill. If you want to make money by auxiliary skills, medical practice, cooking, furniture, architecture, sewing and alchemy are all auxiliary skills to make money. Practicing medicine and cooking need vitality, building alchemy and sewing need physical strength, furniture needs to make drawings with vitality and open furniture with physical strength. Therefore, if you want to earn more money, the recovery of physical strength and vitality is very important, so you need to fill in two points: fitness (increasing the upper limit of physical strength) and health preservation (increasing the upper limit of vitality). I am now 155, and my upper limit of physique is 1385, so my physique is rising faster than others. In that case, if I make money, I will definitely earn more than others under the same conditions and time.
