Health care is not only promoted by cooking. One advantage of learning health care is that it can reduce the physical strength consumed each time when cooking. Health care needs to be upgraded in Luoyang, only J and experience are needed. It is located above Luoyang Animal Museum. If it helps, it should not be necessary, because it is 1-90. I haven't tried. How many helpers are there if you want? Or vigorously develop industry and agriculture. Don't worry about other little things.
