Who helped Tian Ming understand the Yin-Yang curse in the bright moon in Qin Dynasty?

According to Nie Gai's words, he should be an old-timer of Taoist master Xiaoyao, but in the third part, it may be because Mohism is too dangerous in the city, and everyone is in trouble, so it hasn't involved helping Tian Ming understand the plot of Yin and Yang curse! According to the story that has been published so far, the Yin-Yang curse (sleep imprisonment) around Tian Ming's neck has not been eradicated. However, it is inferred here that there are two possibilities for development (of course, not absolute): the first is the foreshadowing left by Uncle Nie Gai, which is the above-mentioned carefree; The second guess is bold, but it is not completely impossible, that is, in the end, it is possible that the moon (Ji Ruqian) cultivated the most profound and mysterious Yin-Yang technique of the Yin-Yang family (she mastered it rationally) and finally lifted the sleep-sealing spell of Dawn.
