Chen Qing Xu supported him to one side and helped him sit down: "Usually, it was when the country was broken and the nation could no longer be preserved that this kind of cruel method would be used, offering blood as a sacrifice to the evil gods in exchange for vengeance. When all the people named ‘Wu Er Gu’ were born, they would all lead to blood-soaked turbulence."

Gu Yun: "You have just said that it was like a kind of poison that harms the people's mind. Could you elaborate more on this?”

Chen Qing Xu said: “Wu Er Gu will turn insane. At first, there will be entangling nightmares. Over time, they will become sensitive and suspicious. If they do not restrain it, it will gradually produce hallucinations. Finally…"

"That is why...," As Gu Yun said these words, his voice seemed to crack. He had to forcefully clear his throat to be able to continue this sentence. "That is why you prescribed him with tranquilizers…”

Chen Qing Xu: "..."

Of course, she knew who Gu Yun was speaking of. She could not say anything, only admitting to it in silence.

Gu Yun closed his eyes slightly — he recalled that Chang Geng had mentioned to him carelessly more than once, such words as ‘too much fire will cause restless sleep’ and so on, yet he had never thought about it carefully, only assuming that as this child followed someone from the Chen family to study medicine for so long, it had turned him delirious, that he had made himself into an elderly man all day talking about health care. But as it turned out...he had so much pain inside.

Gu Yun: "What stage is Chang Geng at?"

Chen Qing Xu remained silent for a moment.

Gu Yun: "You can tell me, I can accept whatever, as long as I am still alive for one more day, whether he is insane or brainless, I will take care of him until the end."

Chen Qing Xu said, "His Highness... His Highness has incredible will, his heart is peaceful. For many years, the Bone of Impurity in his body had never acted up. He himself was also aware of this, thus he has restrained himself much more than ordinary people. Only that a while ago, um... I suppressed it using needles. The Marquis needn't worry about it."

Although she spoke in a vague manner, Gu Yun was able to understand — it had always been peaceful, never acting up, except for the period a while ago.

Because of me. He thought in a blank state, standing up abruptly almost like a corpse coming to life. He stumbled for a moment; his expression appeared as if he had just been stabbed.

He avoided Chen Qing Xu’s helping hand, the rigid supporting steel plate making him appear like an iron puppet that had run out of Ziliujin.
