Super Upgrade System

What is written here? The beginning is exciting, but the ending is very disappointing. Shouldn't it be about ascending to heaven to find girls, battle pets, and brothers through promotion, and lead them to the pinnacle of life? What is this all about? I decided that I haven't finished it yet. There are a lot of typos. Sometimes I can't read the words clearly and the protagonist's name is all messed up. Overall, this book is okay, but it doesn't have a good ending, which is a bit regretful!

I can really pretend to be 13~`

The battle was quite lively, but it seemed rather childish because of the lack of logic. How could one fight for one's life and not keep chattering at the same time? Too wordy.

The best article I have ever seen in my life.

There's no logic, it's awesome all the way, please can you be more reasonable?

Boom, boom, boom, let me come out and talk to myself, there is nothing to see, there is no immersive feeling. To put it bluntly, it's "seeing five things in your head"
