The ancient beasts of the mountains and seas have not died out, they have just lost their divine power and become lodged in the fireworks of the human world.
The Mountain and Sea Soul Store is located in the gap between the mountain and sea world and the modern city. Its business is to store the souls of strange beasts and store the knots in the hearts of mortals.
Alien beasts store their souls: avoid being cleared by heaven, heal their wounds, and go into hibernation. The price is that they must help the trading company complete a good deed in the world.
Mortals store their obsessions: let go of their obsessions and gain liberation, at the cost of preserving an ancient memory for the alien beasts
All the love and hate in the world are separated, and the joys and sorrows of strange beasts are intertwined. The world is healed, and the strange beasts keep their promises.
