Why did the Moon God in Qin Shi Yue Ming cast a yin-yang spell on Tian Ming?

The purpose of this is to prevent him from recalling his memory in the state of Qin.

Tian Ming's life experience is extremely special. His father assassinated Jing Ke, the king of Qin, and Tian Ming's mother was Li Ji, the king's favorite concubine. That is to say, Tian Ming is the son of the enemy of the king of Qin, and it should be a dead end, but the king of Qin loves her so much that she loves me, loves me and treats her as her own.

Extended data

The seal of dawn will be broken sooner or later. The most likely person to unlock the seal of dawn is the moon. The mother of the moon is Yan Fei of the Yin and Yang family, and the moon herself is also a genius of the Yin and Yang family. Presumably, Moon will become the top master of Yin and Yang family and become a master. Obviously, the first thing to do is to help Dawn unlock the seal, and for Dawn, unlocking the seal will be a bloody thing.

Sleeping spell, a kind of yin-yang spell, belongs to ancient witchcraft, also known as "hypnosis ban". It is a profound and terrible yin-yang curse, which is said to make people go crazy and do incredible things. The world thought that Yin and Yang were lost a hundred years ago and reappeared a hundred years later. Because of this, people who can diagnose and solve this spell are almost impossible to find now.
