Why do you say that the fire lives in the shade, the emperor is prosperous in the afternoon, and the tomb is empty? Moreover, Ding Huo also said that longevity is unitary, emperor is prosperous in three, but the ugliness of the tomb is kept in the world? Seek an answer, be urgent

First of all, you should understand that ten days and twelve immortals are different from five elements and twelve immortals. Your question "Fire is born in yin, emperors are born in noon, and the dusk library is empty" should refer to the earthly branches corresponding to the twelve immortals of fire in the five elements (fire, water and earth in Jin Mu). The Ding Huo you refer to is the location of the twelve earthly branches, corresponding to the twelve lifetimes of ten days' work. Its formula is: A sea, B noon, C noon, Geng Xu, Angel and Ren Shen, and butyl is a prime number.
