In the fourth level of the game, the contestants faced a new challenge - playing marbles.Different from the previous survival test, this round of the game requires contestants to team up in pairs and compete together. Only the person who wins 10 marbles can finally win.Under such a setting, contestants not only need to show off their skills, but also need to build trust and cooperation with their teammates.

In this game, the soft-hearted Qi Xun chose a seemingly elderly gentleman as his partner.He originally thought that the old gentleman had Alzheimer's disease, so he used lies and strategies to successfully defraud the other party of the marbles.

At the last moment of the game, the old man suddenly showed off his cards and revealed that he was actually pretending to be ill.He did this just to thank Qixun for his help and care during the game.In return, the old gentleman gave the last marble in his hand to Qixun, which showed the most kind and tender side of human nature.

On the other side, another group of contestants—the female thief Jiang Xiao and the loveless girl Zhiying—also presented us with a touching story.Zhiying revealed that her father had killed her mother with her own hands, and in order to take revenge, she also ended her father's life with her own hands.When she came into this game, she had lost the goal and meaning of life.

Therefore, in the game, she chose to lose to Jiang Xiao on purpose, leaving the marbles to the girl who needed to find her parents for her younger brother.This behavior of Jiying not only shows the kindness and sacrifice spirit deep in her heart, but also allows the audience to see that warmth and care can still exist in the cruel survival game.
