LOL: What does "mid-lane hybrid expert" mean?

In 2026, Li Yi, a popular League of Legends streamer on a short-video platform, died suddenly after an all-night broadcast. When he opened his eyes again, he found himself in 2017, now a mid-laner in EDG’s youth training program. With no talent, no accolades, and no connections, he seemed destined for obscurity—until he awakened the “Every Game Settlement System.” Each time the system judged a match as a “carry win,” he received rewards that steadily honed his mechanics. In time, he became the most “team-oriented” mid-laner the LPL had ever seen. “The so-called ‘art of slacking off’ is really just the skill of climbing the ranks on the Rift. But in the professional scene, I’m definitely an excellent roaming mid-laner. What do you mean my championship was also won by slacking off?” So said Li Yi, the mid-laner who claimed the League of Legends S7 world championship, during an interview, his voice edged with indignation. The very next day, headlines read: “The so-called ‘art of slacking off’ is the art of winning championships on the stage!”
