Review Detail of Bibongsensei in Flashy Adventurer System : Show Off to Get Stronger!

it's good just one or two problems, like the rank,level,stats. in the tournament his opponent was strong , how strong? what is the difference between them?... what is level for? what will happen if he level up?? like it's really useless or not needed is the novel...and the stats, like when you add 1 stat to strength how much does it add?like how strong? and every 10 stats the price of stats will increase by 20, so what is the difference between 10,20,30,40 and so on stats number?... and lastly the name of the mc.. like shye? how do i read that? shey?she?gay? it's quite confusing to read if you're a fast reader sometimes you'll mistake it as "she"... that's all 5⭐👍✨✨🌟
