It's alright but nothing special. The author's hand is a bit too strong oftentimes in the plot. Forced encounters, artificial nerfing the protagonist to stretch out the plot, and buffing female leads by plot armor. The story is not organic and feel quite forced but still somewhat enjoyable.

Another dumb Chinese protagonist. It seems to be the trend nowadays. Copy paste other newer Chinese MCs: idiot, arrogance, lustful, and cowardly. Ofc, always stay at the bottom tier, never truly progressing in personality and strength.

A weakling MC that can't do anything on his home world but abuse other weaker worlds. It's a recent trend/trope for Chinese fanfics, the protagonist barely improves and focus just on improving other characters. There is no real progression.

Interesting that bottom feeder protagonists are becoming the trend in Chinese fanfictions. The main character got nothing going for him beside plot armor to survive.

This is a slice of life novel. It could be interesting but unfortunately the protagonist is very unlikable. He is happy being a doormat, victimized, and led around by the nose/manipulated.

Assassins1 is right. The MC keeps on getting nerfed while enemies are getting buffed. No matter how strong the protagonist gets, the opponents will get stronger. There's no progression for the MC. Only the characters around him do get stronger.

Even with the system, the protagonist win ratio in competitions is mediocre. It's a really boring novel about a mid 20s reincarnated person competing against elementary students. He still loses quite regularly.

The problem with this story is that the system is superfluous. It's mainly just for gag. It doesn't matter how strong the MC got, he'll get nerfed or buffed according to the plot. There is no real progression based on the system. It's an OK read when you're bored. Nothing spectacular.. just middling, a bit below average.
