Episode 21 recap: Old Wang took Xiao Wang to the equipment room.

On the blackboard in the police station, the clues and evidence of the entire case were clearly written. Old Wang anxiously made a phone call, but the other person, Old Zhou, seemed to be in a hurry to hang up. Old Wang straightforwardly asked the other person not to hang up, and he even pleaded with him. Old Wang argued that this was a serious matter and not a violation of the rules. Moreover, he had already filed a report. Old Wang made the call just hoping that the other person could help. Old Wang also mentioned that he just wanted to take the child out to see the world!

After begging for a while, it seemed like Old Zhou finally relented and quickly agreed. He told Xiao Wang not to leave and that he would take him out to see the world! He even said it was a good place there! Afterwards, Old Wang took Xiao Wang to the equipment room. Xiao Wang was puzzled why his mentor brought him here because this wasn't a place he would normally go to. Old Wang straightforwardly said it was for him to broaden his horizons and asked Xiao Wang to pick one of the three boxes in front of him to open, treating it like opening a blind box. Xiao Wang was surprised that his mentor knew such trendy vocabulary and jokingly said he knew what was inside even without opening it. It was then that Old Wang remembered that Xiao Wang was an outstanding graduate from the police academy. Old Wang chuckled and suggested they go back, but Xiao Wang quickly stopped him. Then Xiao Wang faced the three boxes in front of him, which were night vision goggles, a drug and hair detection device, and a comprehensive data collection instrument.
