"something (grimdark power-scaling quasi-isekai fantasy) that likely appeals to Chinese netizens"

There's a huge amount of that stuff appearing as Chinese AI-created dramas. Although there seem to be only about ten standard plots. ("Banished girl heiress returns from the countryside to rich family" is very popular. Some of the vertical dramas with that plot are so similar it suggests re-use of the same prompt. Incidentally, if you don't watch Chinese drama and want to, see "Princess Agents", the original. That's a pre-AI big budget project with good plotting and characters.)

The AI fear for China should be that people will have to leave their city job, and return home in shame to their village, and farm. AIs and robots do most of the city work. There are still rich, modern, cities. You're just outside them.

The drama version would start like this: An employee is called into their boss's office and told they are being replaced with an AI. They pack their belongings into a cardboard box (a cliche of Chinese drama) and walk out of the building. When they get home, a petty official visits them and tells them their hukou is being revoked for being unemployed. Then we seem them with a small suitcase getting on a green train, headed for oblivion in the countryside.
