"Uzi the Expert" might be referring to the character Yu Wenzhou in "The Expert". Yu Wenzhou was a character in Butterfly Lan's eSports novel,"Full Time Expert" and its derivative works. He was a professional player in the Glory Alliance, the first "Warlock" to debut in the Glory Alliance, and the first "Double Hundred"(100 MVP and 100 Best Lineups in a single season) record holder. He had created the character Swoksaar in the tenth server and was known as the Tactician due to his meticulous control and precise calculations. During his time in Team Excellent Era, he had always been the captain and commander. But because his hand speed wasn't fast enough, he relied more on his awareness and control to make up for it in the game. He was known as "Glory's Strongest Brain." In the novel, Yu Wenzhou's appearance and fighting style were similar to the professional esports player Uzi, so he might be called the "full-time expert Uzi."
