How to upgrade the equipment for guarding Jiange? For example, how can Long Lin reach its peak?

The more times special weapons (such as 1 level) hit monsters, the higher the level, and the more times armor monsters hit you, the higher the level. Ordinary (that is, shop sales) can go to the nearby weapons store for 3000 times. You can go to the upper right corner of the map. There are good things to sell, but they are expensive. You can go to the hunter to brush the skin.
