After Xuanyuan unified the Terran, in addition to persecuting the Jiuli tribe, he did fairly well in other aspects. His Yuanfei Luozu was very virtuous and created the art of planting mulberry, raising silkworms, drawing silk and weaving silk. With her help, Xuanyuan gradually gained the recognition of the Terran. However, in the late stage, Xuanyuan failed to achieve success because of his heavy killing and cutting. At this time, he was very anxious. Guangchengzi, as the teacher of the emperor, was also very anxious. The emperor could not share the merits of the emperor without preaching. Unfortunately, he didn't know that he couldn't get much merits even if Xuanyuan achieved the way of the emperor due to his own fault.

After thinking for several times, guangchengzi finally came up with a method for Xuanyuan to quickly prove the way of the emperor, that is, the double cultivation method of yin and Yang. Xuanyuan was also worried that he didn't know when he could prove the way. After receiving guangchengzi's double cultivation method, he gathered beautiful women all over the world and finally picked a hundred female Yuan Yin to become immortals to prove the way of the emperor, So later generations had the theory that Xuanyuan became an immortal by controlling hundreds of women.

Xuanyuan's merits and virtues perfectly proved the emperor's way. Unfortunately, he killed too much evil himself and took a hundred female yuan to undermine his merits and virtues. Although heaven's way protected him, he damaged too many merits and virtues, and his prestige in the world was far from that of emperor Fuxi and Emperor Shennong. At the time of his preaching, only the supreme Lao Jun, the leader of human education, and the first emperor of elucidation came to watch the ceremony, All the other saints felt that Xuanyuan didn't do much to preach, and he didn't do much in his way of doing things in the Terran, so he didn't go to watch the ceremony. Kunpeng, a Terran saint, should have gone, but he advised Xuanyuan several times to no avail, and he was angry and didn't go. Fuxi and Shennong were emperors and went to watch the ceremony. Looking at Xuanyuan, Shennong blamed himself for not choosing the right successor, which led to such a huge loss to the human race.

In this way, Xuanyuan preaching is also the most rudimentary of the three emperors. The Supreme Lord is the leader of human education, and the emperor is nominally under his jurisdiction, so he had to come to observe the ceremony. The first emperor of the Yuan Dynasty, Xuanyuan's master, also had to come to observe the ceremony.

Xuanyuan's meritorious deeds and virtues came down from heaven, which shocked the first emperor of the Yuan Dynasty and the supreme old gentleman. His meritorious deeds and virtues were too different from those of emperor Fuxi and Emperor Shennong. He only improved his self-cultivation to the later stage of Da Luo Jinxian, while the teacher guangchengzi of the Emperor of the people only had a small trace of meritorious deeds and virtues, which was still because he was the result of the emperor of the people, Otherwise, I'm afraid these merits and virtues can only make him have the cultivation of Jinxian in the later stage. Such a result makes Yuanshi Tianzun and supreme Lao Jun feel unthinkable.
