I've been a fan of solo leveling and even finished it's novel. At first I was intrigued since this type of stories are what I am into however as I continue on reading I keep on feeling this deja vu until the game system and quest arrived. Everything was fine until the exercise part and the punishment explanation. That's when I knew that I got into this because it's very very similar.... absolutely very similar(identical) to solo leveling. With few changes it was like I'm reading a fanfic version instead.
