BOSS level and two chip levels are often brushed five times a day without a chip. If you encounter a situation that you will not be out for a few days, you should save it when you are about to upgrade. It is best to prepare an experienced card. If you brush it five times a day and upgrade immediately after eating the experience card, then our physical strength will be refreshed again, 100 is full of t, and then you will be brushed again. How can you go out this time?
Personally, don't change grades repeatedly, but if there are grade fragments, everyone should change them immediately, otherwise the probability of the same grade is relatively low.
