Hey, it's good that you managed to solve the problem with your pc and especially the hive passwords, you have to keep them well stored in several copies to avoid losing them.

this story looks interesting, I don't usually watch much manga or manhwa but it looks curious, it has good quality although as you say the plot is both interesting and dangerous for the author, creating a character that can become very strong almost effortlessly is something that tends to get boring very quickly if you don't know how to handle it, it's a shame that as you mention just this happened, maybe with a more comical approach or with an indifferent character you could have more balance with his power.
