Probably in how the player is able to level up or acquire rarer items based on previous knowledge (this time passed onto him by his brother not a previous life). It isnt entirely given to him, he uses his previous knowledge to work hard by his own merits. Also the magical components of the world and the fact that he can have a beast?
I love how its a mix of all my favorite series: solo leveling, the tower of god and the beginning after the end lmao
