The system is just for fun. If you really want to be happy, you need runes:
He sets up shop in the world of swords and sorcery,
He also opened a shop in the world of cultivation,
He is also mining and opening a store in the post-apocalyptic earth.
He opened it in the mysterious Rune Wilderness, but this one couldn't be opened, so he staged wilderness survival in the Rune Wilderness.
Oh, right,
He is a salty fish.
