Fox Spirit Matchmaker: The Strongest Exchange System

You are writing about other worlds in the world of the fox demon Little Matchmaker. Although it is said to be filling in the background, don't add it to the main text! I was confused at first. If I hadn't straightened it out once, I would have started spraying. It gave me a headache to watch. Then the protagonist upgrades too quickly, and a bunch of forces and realms are added (I'm not sure if they are original or added). Personally, I feel that it might be better to set it according to the logic of animation. After all, I only watch animation and not others.

A child less than one year old. How big can it be. Babies walk, babies tell. And she's a saint. Looks so awkward
