When Nu Wa mended the sky, she used the ancient energy from the five-color divine stones to rebuild the order of the heaven and the earth. This sacred stone comes from the universe and contains the power of the stars, and these powers interact with each other. At the moment of mending the sky, a large amount of original qi in the ancient sacred stone leaked out, and a large amount of original qi was injected into the mountains, rivers, flowers, trees, birds and animals on the earth. In the process of mending the sky, Nuwa cut off the four feet of the giant turtle in the sea as a support. When the giant turtle was dying, the resentment and evil thoughts in its heart eroded the god stone. Although the five-color god stone contained endless energy, But the evil thoughts hidden in it can resonate with the evil thoughts in human hearts. After Nuwa mended the sky, she felt that somewhere, there was an evil force growing, and various visions continued to appear on the ancient continent, but too much divine power was spent in mending the sky, and now there is no way to find this evil force source. Therefore, she selected some gifted people and taught them to collect the original energy between the heaven and the earth to strengthen their own strength, so as to fight against possible threats in the future. People were surprised to find that the meridians and acupuncture points on their bodies complemented each other with the stars in the sky. , plus the power of the original qi, they can actually summon a patron saint with a certain power to assist them in training and fighting. These people who collect Qi are collectively called "Xing Qi Masters", and the patron saints they summon are called "Qi Spirits".
