It is to discard the X card, not to discard the X card. For example, if you have done it eight times, you can discard it to eight, provided that you have eight in your hand. If you don't have eight, you don't have to discard it!

In other words, you may be easier to understand. Although many descriptions of the Three Kingdoms killing skills are awkward, you can understand them simply. After the stage is over, you can choose to start advancing. After you start, you can touch 2 cards, and then the upper limit of your hand becomes X, and X is the number of times you start the surprise system this round.

(as for why the official does not describe it like this? ) Because this skill will conflict with Cao Rui's skill. For example, the upper limit of your hand is 3, and Cao Rui's reason makes you 4, but if you want to fold your hand to only 3 after launching the advanced game, then you will waste Cao Rui's skills.
