The mortality rate in Zhou Tai is calculated by mathematical experts. It can be seen that, under normal circumstances, Zhou Tai's five indomitable peaches are generally needed. Of course, due to the probability, there will always be lucky golden guns that will not fall, and there will also be two squats with bad luck. I have recorded before that one day I will lose two or three pieces when I fight the national war!
Perhaps selective card-discarding will help Zhou Tai to be unyielding for many times, but it has little effect, and the pile of cards is too big for Zhou Tai to control by discarding a few cards.
