the problem with the story is that you showed how strong the mc by unsealing his cultivation then immediately seals it again lol.. it will leave a bitter taste to some of the readers if you "weakened" or nerfed the mc. you shouldve just started with the mc's cultivation being sealed. so there is no weakening that is happening. and the only way for the mc is up/stronger which would be good imo..

theres no point in reading a couple more chapters if the earlier ones are already a pain to read. guess its not just my type of mc..
