About the Shenxin tribe
The people of Dayu all respect the God of Light. According to legend, in ancient times, the God of Light once sent twelve attendants to the world to quell wars and save people from fire and water. But the waiter spent all his spiritual energy to drive away the demons and became a mortal after entering the cycle of life and death, unable to return to heaven. The God of Light issued a decree, asking the attendants to spread the Dharma of Light in the world, and named the Xin clan of God. However, the Shenxin people who serve the God of Light are all men with pure Yang bodies, and cannot be affected by Yin energy, and cannot marry women. In order to allow the Shenxin tribe to multiply in the human world, the God of Light bestowed fertility on the Shenxin tribe, allowing the Shenxin tribe to be passed down from generation to generation in the human world.
After Emperor Taizu of Dayu, Mu Yuanji, ascended the throne, he issued an edict that for any family with a title, the legitimate son could marry a Shenxin clan member as his wife Xin. If Mrs. Xin could give birth to an heir of the Shenxin clan, the title would be passed on, otherwise the title would be revoked and demoted to a commoner. The prince, regardless of his legitimate concubine, can marry Mrs. Xin. Similarly, if there is no god Xin, his heir cannot inherit the throne. Moreover, the edict also clearly states that Mrs. Xin's status in the family is the same as that of the royal wife. If Mrs. Xin enters the house early, the royal wife must also treat her with the courtesy of an elder brother. After the prince ascended the throne, Mrs. Xin was registered as a divine concubine and stood shoulder to shoulder with the queen in the harem. This decree clarified the status of the Shenxin tribe to the political level, and the status of the Shenxin tribe immediately became extremely noble, no less than that of the royal family.
