Review Detail of Dark_Life_1 in My Power is Upgrading Everything (Rewrite)

It's an interesting story as mixture of hardworking and overpowered character with system. I like this story as it has good background and story development and it's character is also good has intelligence but a little naive. Totally it's a good story. It's just characters never showed their all out powers and some scenes like that where character don't use all his power and villain have more time than needed.
