If there were complete explaination of this sh** concept though not overpowered it would have been a great 5/5 stared one type just cause of this simple concept but yeah story is great and why explaination and concepts and time to time explainations why? Simple it would lengthen the manhwa as well as give it as great taste why ruin the mood of this manhwa like this this is not even worth 2/5 now just every now and then it confuses me and even question arises as well not the questions about upper floor of babel and later part of story but the wh*** 1-17 chapters not his regression but his toery about glutonny and how much they strengthened its just like here they fought and grew stronger like he** even shi*** story with player concept will give proper explaination of how much stronger even though in some player types stats are not shown but gives clear concept of how much strong the mc becomes even as arbirary guess
