Weird Story About Rules: My Card Breeds Ferocious Beasts

[Unlimited flow + cards + folk horror + beasts from the Classic of Mountains and Seas + poisonous tongue + weird rules + spiritual energy recovery + counter routines] In the third year of the revival of spiritual energy, the gap between reality and the card world is getting wider and wider. One second the streets are busy with traffic, and the next second the gluttons in the Classic of Mountains and Seas may burst out and swallow up half the street in one go. This is not a novel, it is happening every day. People all over the world are awakened to cards, but 99% of people can get good cards in their hands, and all they get are auspicious beasts. And I am the unlucky guy. When I open the card, I will get the devil door card. What is hidden behind the door is not an ordinary ghost, but a beast from the Classic of Mountains and Seas wrapped in a folk horror shell. Each one carries the original sins of greed, anger, and ignorance of mankind. I originally thought I was special enough, until I met Lingzhoudu. This guy was different from others in that he had no cards in his hand. Now there are more and more cracks. It is said that in three months, the two worlds will be completely integrated. By then, instead of people killing ferocious beasts, ferocious beasts will devour people. I have to quickly break down a few more doors and collect more ferocious beasts as pets. But no one knows that the ferocious beasts behind those doors are actually made of human beings' own desires. What we break is not the door, but the ghosts in our own hearts. And when the last door is opened, standing behind it may be something more terrifying than a ferocious beast...
