This is the boy band NZND formed in the third issue of the first season of "Star Detective", "The War of Fresh Boy Groups". A boy band composed of He Meinan, Bai RAP, Sa Xiaoxiao, Zhang SOLO, and Chen Wu.

The slogan of the group is: "nznd why you try, mdzz will accompany you high". In fact, if you translate it, you will know why the nznd group is called the mdzz group by its fans. nznd actually means no zuo no die. When fans give it mdzz, it actually means ma de zhi zhang. Just imagine that group would use such a weird name, so they don't want fans to call them mdzz.

The group not only has fixed members, but also has its own album single "Will You Still Love Me If I Drive an Excavator?" It is reported that in the fifth episode of the third season of "Celebrity Detective", it was revealed that the NZND group is about to hold its first ten-year concert, for which the audience is also looking forward to it.

In fact, this group was only launched to match the plot setting of "Star Detective" and is not a real group. The members of the group are He Jiong, Bai Jingting, Da Zhangwei, Sa Beining, and Chen The roles played by five Ruo men. The concert was just for the plot setting in "Celebrity Detective", and there was no such concert in reality.
