Singing nursery rhymes together
Wang Yun had been unconscious for quite a while. Before the middle-aged man attacked "Old Xu," Wang Yun had already started foaming at the mouth. Now that the skirmish was over, he still had not regained consciousness.
Fortunately, the middle-aged man had seemingly not wanted to take Old Xu's life. Therefore, the poison in the hardtack was only to paralyze "him" and not to kill.
A group of people surrounded the unconscious Wang Yun, with four of them being his subordinates. They had stopped pretending and quickly checked on Wang Yun's condition. They were only relieved when they could confirm Wang Yun was only unconscious.
After they checked him, the four of them looked at each other in dismay. Ever since they joined the team, all of them acted like they did not know each other and did not even communicate with one another.
