He still wasn't able to do everything by himself without dying. It urges me to drop it😔

MC is not talented though. He has to work hard to progresss and it just so happens he gets more time by dying.

It’s kind of irritating but I get it

It might be irritating at first but it'll grow on you as you read. They'll only be showing numbers of times of his death rather than the whole battle during those times and it adds more impact to his frustration at the same time determination to get stronger each battle.
