"Blood and flesh," Chang Geng was silent for a moment, shaking his head and smiling bitterly, "What Miss Chen means is that my entire body is poison, unless I follow the myth of scraping bones and picking flesh?"

It seemed that this was much worse than having a ruined mind.

Chang Geng unhurriedly sorted out the herbs and put them in containers in order. The gears on the shelves clenched together with a squeaky sound and slowly rose to the top to reveal the empty space below. This was meticulous work, it could not be done by an impetuous person.

Chen Qing Xu looked at him with admiration. There was no historical record of those who were entangled by the Bone of Impurity but could still stay sane until adulthood, let alone one who could maintain such a calm and gentle temperament.

There was no telling whether he was born with perseverance, or if he was better than the others by one Gu Yun.

Chang Geng: "To tell you the truth, I haven't felt very well recently. The Bone of Impurity attacks are becoming more and more frequent."

Chen Qing Xu casually said, "The Marquis already told me."

Chang Geng was startled for a moment, "He..."

Gu Yun always seemed to follow the attitude of 'it was only the barbarian witchcraft poisoning' and never took this 'minor skin and flesh illness' seriously. He seldom talked about it and never showed any concern in front of Chang Geng.

Turned out...it had always troubled him?

Chen Qing Xu paused and realized that she had said too much. She shifted the topic, "Your Highness, if there is nothing else to instruct, I'm going to return to the Chen family's old residence in Shanxi. It will be much easier after I find the roots, there will be a solution in the end."

"Ah," Chang Geng answered, putting his hands together, "I have troubled you, and about Zi Xi's antidote..."

He was interrupted by a visitor from the palace before he could finish.

The medicine disciple brought in a servant, who respectfully greeted Chang Geng and said, "Your Highness, the Emperor heard that you are ill, he had specially asked your servant to come and see. I also brought along a doctor, but he did not dare to enter Doctor Chen's courtyard and is waiting outside."

Chang Geng frowned: "I have troubled Royal Brother for his concern, but I only caught a regular cold, not a serious illness."

The servant laughed and said, "Yes, I also saw that Your Highness was in good spirits, eh... Your Highness, there is a banquet in the palace this evening for the Third Barbarian Prince and their group of envoys. The envoy of the Eighteen Tribes mentioned Your Highness in front of the Emperor. His Majesty ordered me to tell you that if your body isn't feeling well, there's no need to trouble yourself, but if you're feeling alright, you should come join in on the fun."
