First of all; With the continuous updating of Dungeon and Warrior versions and the gradual enhancement of their levels, the profession will constantly change the replacement of equipment, so the top equipment may need to be made by brushing the abyss, so the explosion rate of the abyss has always had a certain value, which has a certain impact on the flash. It's like opening a magic box in Dungeons and Warriors. If you don't open a box, you will get some lucky values when you start ten boxes.
So for this, in fact, the same is true for brushing the abyss. For some professions, such as your friend, the abyss keeps flashing, probably because his account is of high value. Here, I don't know if you know two opposing words that are popular in the game now, European emperor and black number. Then the so-called European emperor refers to your friends, that is, accounts with higher value, and vice versa.
So for these two accounts, this is the reason that determines the probability of abyss flash. So for the numerical level, I don't know if you have seen such a passage in the game, "I don't have the funds to protect Arad." In fact, this sentence can completely prove everything. As the game itself, it is for profit. If every player in the game can easily experience the highest effect of the game, then the game has no profit at all, so what I think here is the probability of abyss flash. As your friend said, it has something to do with money. However, this view only represents me personally, and I only hope it can help your problem!
