MC is an overconfident idiot. Second chance in life but failed to protect his grandma due to his ego.

The author likes to babble and repeat sentences. Readers know that the mc is a reborn person, no need to tell it many times. author likes to contradict himself. At first he makes mc to not want many people in his base (quality not quantity) and then he recruit a lot of ordinary people. After a few chapters, he wants to take over a big survivor base because it has many survivors. Make up your damn mind. Few or many? And why authors have to have hero complex? What’s wrong with few people but great fighting powers?

Author likes to waste words with ‘filler scene’. So much explaining and the plot stagnated. Early chapters less babbling and more story plot. But later, it felt like author treated the readers like kids, everything needs to be explained. Dude, we got Google.
