A long time ago, when gods and demons still existed, humans and gods and demons at that time formed three different countries.
The gods live in the Kingdom of Clouds on the top of the mountains; the demons live in the Kingdom of Water at the bottom of the sea; humans live on the earth, which is called the Kingdom of the Earth.
For a long time, these three countries with completely different regions and cultures have existed as tripartite pillars without interfering with each other.
Until one day, a prophecy appeared and broke the balance of the world.
The prophecy says that the twin stars "Advance" and "Shou" will come to the world and, with the help of stargazers, will unify the current world into the only kingdom of stars.
Intention: 20 years of perseverance, congratulations to ac on welcoming he, and a conclusion to my perseverance.
