Seems like your typical zero to hero power fantasy system manwha. Nothing special about it in fact it seems even worse that your typical garbage. Here is a quick summary: Mc is a weak minded little loser that gets looked down on for being weak... which he is. Then out of actual no where he gets sent to your cliche leveling tower where mc starts doing cliche trials to become strong. Somehow he learns to actually fight and be competent even though it was clearly established that this guy can't do sh**, but all of a sudden he becomes cool and strong. Then after mc gets his mandatory power up he comes back then starts sucking peoples dicks and looking for validation with his new found power. Because guess what happens when a little kid gets a new toy, he shows it off to other kids. Then the other kids start wanting said new toy so they betray kid #1 to get the toy. Btw for the brain dead children who don't understand the metaphor (and probably enjoy this kind of manga) the kid here is the mc and because he is a weak minded little bi*** he relies on his flashy new plot armor to flex on other characters, BUT then the other characters take advantage of little bi*** gullible mc aaaaaaand you know where this is going. 

Now that the summary is over here is my rating: It's bad. It's just bad no more no less. This is another copy paste system power fantasy manwha that you've read 100 times now. 0/10. This is another typical solo leveling clone and a really bad one at that. I've said it before and I will say it again solo leveling is the best system leveling manwha ever and it will always be the best. But I'm not here to critique solo leveling that is a topic for another day.
