Nuwa first made human beings by making clay figures by the Yellow River. They were shaped like her and were made with great care. After she became an adult, Nuwa personally named her "Wa". Nuwa thought for a while that there couldn't be only one kind of person in the world, so she made another little boy and named him "Si". Nuwa thought that people like this were quite nice, so she dipped a tree branch in mud and sprinkled it with water, and thousands of people of all kinds appeared in the world.
And Si Hewa was the first male and female villain that Nuwa made. Nuwa thought they were of great significance, so she gave them divine power, allowing them to live forever and protect a very important thing in Butian Ridge - the Butian Stone.
One thought becomes a Buddha, one thought becomes a demon. What does the sword in your heart look like?
