The ownership of the blank cards is a highly controversial issue, and now it's uncertain whether the six blank cards on Qian Cangyi belong to him or to Qian Jiangyue and his two companions, a problem that cannot be resolved merely by arguing.
Ever since the game started, there has been no consensus on whether the person who obtains the Corpse Card should own the blank cards after being saved, thus, the rescued individual would naturally not completely give up their right to the blank cards. It is for this reason that Qian Jiangyue and his two companions have been battling for the ownership of the blank cards.
There was no need for the three of them to act this way, but Lan Jing, Wang Qi and Cao Ya would definitely not have such deep trust in Pei Junliang, so they would act accordingly, and the roles Qian Jiangyue and his companions were playing were exactly those three.
