"It does not matter who the mother is. There's not much difference between the Eighteen Tribes' witch and the witch's sister. The problem is...whose child was Hu Ge Er carrying?" Shen Yi licked the corners of his dry lips with difficulty.

That year, the younger sister of the consort also lived in the palace, she was to be wed to someone of royal bloodline. Would former emperor Yuan He commit such a thing as stealing something he was keeping guard of?

If the former emperor truly was this shameless, it would be a relief to everyone, but what if...it wasn't so?

If it was not the former emperor, there was no doubt that the most suspected person would be the one who had helped the two women escape at that time, who harbored ill intentions, but was able to enter and exit the palace, even had the ability to release the Eighteen Tribes witches, then took over the line of spying that they left in the palace many years later...

With all these conditions combined, one could easily be reminded of Master Liao Chi and his group of Dong Ying spies.

Shen Yi felt cold all over: "Marshal, this..."

Gu Yun looked up at him, his eyes resembling sharp blades, Shen Yi suddenly could not open his mouth.

"Digest it in your stomach." Gu Yun lowered his head and stroked the knife with both hands: "On the Northern Man side, I will clean it all up sooner or later. Don't mention this matter anymore."

Shen Yi: "... Yes. "

Gu Yun's face was as heavy as an iron. His back was supported upright by the steel plate, making him appear all the more heavyhearted. He went to find Chen Qing Xu himself.

"Miss Chen, I would like to have a word with you."

Chen Qing Xu did not know what was going on, she followed him to one side.

Gu Yun said, "Miss Chen is well-versed in medicine, you have also been in the barbarian area for half a year. I have a question to ask you."

Chen Qing Xu hurriedly lifted her robe and bowed: "I dare not.”

Gu Yun absentmindedly gave her a hand: "Do they have any special witchcraft there...that makes use of babies?"

Chen Qing Xu was startled.

Gu Yun immediately caught her surprised expression in the blink of an eye: "What's wrong?"

Chen Qing Xu was silent for a long time. She paced restlessly in the same place for two steps. Then, she sighed deeply: "Marshal... have you ever heard of the Bone of Impurity?"

Gu Yun frowned and carefully recalled for a moment: "It sounds familiar. I've heard that...it seems to be a kind of god from the North?”
