Unfinished event book Many players think that this game has a low probability of drawing cards at present, and many people vomit that they are Africans. So what is the card drawing mechanism and guaranteed probability of the undecided event book? The following small series will bring you analysis:

About card drawing

At present, the overall ssr probability is 2%, so if the influence of small guarantee is not considered, it is 50 ssr.
