There is such a planet in the vast universe. Its surface is in the shape of yin and yang, with one side being light and the other side being dark. The light side is called the continent of Qi. It is mainly surrounded by an energy called Qi. There are a group of people living on this continent. They are born surrounded by this kind of Qi. This Qi will provide them with energy, and they can use Qi to live on this planet. Qi mainly comes from the natural forces on this planet, so Qi is mainly divided into seven elements-water, fire, earth, ice, wood, wind, and thunder. The seven elements are mutually reinforcing and restraining each other. The entire continent of Qi is composed of these seven kinds of Qi. They restrain and merge with each other to maintain the stability of this planet.
