Yuan Qingyu, a peerless European emperor, was defeated by a card drawing game! "Gray Balance" is a Mingke fan game. I don't know who planned it, but it reduced the probability of drawing cards from the card pool so low. After a year of hard work, I finally gave up. But he didn't expect that he would be selected by this game to travel through time!
Intention: To relieve the difficulty of calming the mind and create a balance between red and black.
