In "Coloured Glass", why didn't Brother Hao Chen let Xuan Ji read the book that robbed the mirror of eight sides?

In the TV series "Coloured Glass", everyone knows that Chu Xuanji is the reincarnation of the god of war, and the god of war was banished to the world to practice again because he violated the rules of heaven. In fact, Chu Xuanji was a hermaphrodite dark emperor in his last life, and was the capital of Luo Hou, the general of the God of War of the Shura clan. Luo Hou Ji is a Shura clan, but he is good friends with the Emperor Bailin. Later, the Shura clan went to war with heaven, and Emperor Bailin used the means of community. His soul was put in a glass lamp, and Du Ji's soul merged with the glass lamp to become the god of war, which was used by the heaven.

In this play, the mirror of the four seas and eight barren places is the artifact of the Queen Mother of the West. If you find it, you can restore your six senses and know who you really are. With the development of the plot, everyone knows the identity of the Hao Chen brothers. He is the king of Berlin in heaven. The reason why Chen Hao didn't let Chu watch "Four Seas and Eight Wild Mirrors" was because he wanted to cover up the truth of killing Luo Hou at that time.

In fact, Emperor Berlin has always had the capital to offend Luo Hou. After all, they used to be best friends, but for the benefit of heaven, Bai Lindi betrayed the capital of Luohou. Therefore, Bai Lindi has always been concerned about this past. Luo Hou Ji died, and it's no use crying over spilt milk. He can only turn Chu Xuanji into a fairy in this world with guilt. The god of war is very powerful. If the power of the god of war can be effectively used, then the heaven will always be peaceful. Therefore, the Emperor of Berlin will make good use of the power of the God of War, and will not easily let Chu Xuanji discover his true identity. One more thing, Hao Chen also has his own thoughts. In the process of getting along with Chu, he has developed certain feelings for her. Although he doesn't know his own psychology, in fact, he has shown it in the plot, so Chen Hao wants to selfishly leave Chu Xuan alone with him. But what he didn't expect was that Chu, with the help of Yu Sifeng, slowly recovered his six senses, finally rediscovered his past life identity and revealed his crimes.
