I Was Hong Kong Island’s Resident Punching Bag

How long has it been since he transmigrated? He still doesn't know anything. All that time spent as an extra in the Long Family Stunt Team and at the boxing gym was for nothing; he hasn't learned a single thing. The protagonist seems like a useless bum who only knows how to add charm. It's getting more and more awkward to watch.

Is the protagonist's system only for collecting pain points by getting beaten up? But he also gets pain points from jumping off buildings while doing stunts at the beginning. If physical pain is the only way to gain pain points, the protagonist could just learn basic physics and electrical engineering, make an electrocution device to electrify himself, and the pain would reach the level of…

This system is a waste if you don't take it to the space and amusement park to roam around as a tank. Seriously, in the real world, the higher an individual's constitution, the harder it is to gain pain points; it's like getting hit doesn't hurt at all. Unless you intentionally get hit by a weapon, you won't gain pain points because it doesn't hurt.

Author, you're getting beaten up to become stronger, not just for the sake of being beaten. The protagonist spends so much time in the boxing gym without learning to fight because boxing doesn't generate pain points. He has a good relationship with Dadan, but never considered learning martial arts from him. He relies entirely on temporary system items to get by.

Why add English words after strength and agility?

Constantly gaining experience points by taking hits will become increasingly difficult to write later on. Using items continuously in combat with enemies feels like running a dungeon and grinding monsters, which feels awkward. In the battle against the Sanctuary, the items used seemed to outweigh the rewards.

This system is more suited to martial arts worlds; it'd be too overpowered in a police and gangster action movie!

So there's a reason why there are few comments.

What kind of writing is this? I'm completely baffled!
