The System Arrived Three Years Before the Apocalypse

Yes, it's a post-apocalyptic story. You can describe the preparation process in detail, but what's with the protagonist constantly playing matches?

Well, it's like a sports-themed fantasy novel. A lot of time is spent on playing matches.

Let me know when you're no longer boxing; I watch science fiction, not sports.

You have a system, you're three years ahead of schedule, why can't you save humanity? Why do you have to cower in a refuge?

Is it really okay to carefree chat and practice flirting with a colleague who will turn into a zombie in three years every day? Doesn't it make you feel uncomfortable? Won't your relationship grow stronger over time?

The protagonist has some serious ideological problems!

This is a story about boxing, not an apocalyptic story.

The biggest problem is that the protagonist isn't preparing for the apocalypse at all. If you put yourself in the protagonist's shoes, you'll find his actions very strange, and his attitude towards the cheat system is also very strange (he doesn't seem to be thinking about how to quickly gain points).

This writing is utterly nonsensical. Like that earlier part about the group fight? All sorts of people coming up to fight, I had no idea what it meant, what the cause was, and it was all so incomprehensible. All those different kinds of fighters—sumo wrestlers, boxers—taking turns beating the protagonist, and then the group brawls—it all gave me a headache.

It's so drawn-out and tedious. Even with all the characters having cheat codes, they add tons of restrictions, as if afraid the protagonist will develop too quickly. I've only read a few chapters of the story, and it's all just boxing—it's boring.
