Also just a suggestion don't take it as criticism or anything mc has a gamer system so if mc will seal zetsu away why just keep a dream of traveling the world why not multiverse there are several world's where you shouldn't need to nerf the mc but still will be able to continue or you can put quest based restriction for travelling the world where your strength is restricted till you complete certain objectives or simple mc making some jutsu to travel the multiverse but only his soul with the system survive and he is in another world Please to consider this suggestion
Will practicing fuinjutsu increase any of his stats? Think the timing of starting sealing training is good, because he should be able to help Naruto, Sasuke, and himself if Orochimaru puts seals on them. Also means the path to edo tensei has possibly begun. Looking forward to what you have planned. Also, will we get an update on the progress of the Tier 2 seal soonish?
