In order to refine the Hongmeng Taoist body faster and become invincible, Chu Yuan chose to use it to customize the system for his tribe. "You like to swing a sword. Learn about the sword-drawing system. You can become stronger by drawing a sword. If you draw a sword hundreds of millions of times, with one sword strike, the saint will fall, and the world will be sad!" "You and demons are at odds with each other? You deserve the demon-slaying and demon-slaying system. Killing demons will make you stronger. Kill the demon emperor and you will be able to realize the path of Hunyuan!" "You just want to sleep peacefully. The system of many children and many blessings is tailor-made for you. As long as you marry a wife and have children, you will become stronger..." … Countless years later. In order to refine the witch-slaying sword, Demon Emperor Jun massacred human beings. Nuwa did not come out, and Taiqing watched coldly. Tens of billions of human beings were about to be slaughtered by the demon clan. A sword came from the west and killed the demon emperor.
