"I will go and supervise, lest you secretly concoct some kind of quack poison to harm people," Shang Xiye said indifferently.

Ji Fengyao: "!"

She hated her own hands!

I've said hundreds of times I'd kill him with a needle, but why haven't I managed to kill this heartless bastard with a single needle?

However, thanks to this heartless scoundrel, Ji Fengyao learned that there was actually a secret passage in her bedroom that led directly to a hidden room in the underground courtyard. She was so relieved that she took out the heavy gold seal from her bosom and casually placed it on a wooden shelf on one side of the secret room.

Wuhen: "..." Your Highness, that's the golden seal of the royal family that can sell the royal palace!

Inside the secret room, Black Owl sat amidst a pile of more than a dozen large crates.

Next to the box, in a chair, sat a blind old man trembling with fear. Every now and then, the old man would ask in terror, "Is anyone there? What do you want with this blind old man? I've lived a poor and lonely life. Please let me go."

No one answered him, and Ji Fengyao remained silent.

After preparing the brush and ink, Ji Fengyao nodded to Hei Xiao.

Black Owl stood up, opened a box next to the old man, took out a wooden box, and then took out a dried herb from the box and handed it to the old man, asking in a deep voice, "Old man, can you identify what kind of herb this is?"

"This is..." The old man sniffed the herbs in his hand and said, "This is a creeping fruit. The white-skinned fruit helps to clear phlegm and reduce swelling, while the black-skinned fruit gathers yang and nourishes yin. This fruit has a fishy but bland taste, which is the white fruit; the black-skinned fruit tastes sweet."

Wuhen handed the wooden box from Hei Xiao's hand to Ji Fengyao.

Ji Fengyao took a small piece from the box, sniffed it lightly, and wrote down two names on a piece of paper.

Shang Xiye glanced up and saw that the name she wrote was "Fudiguo" in the Da Zhao script, while the other script was one he had never seen before. However, he felt that the characters were familiar to him, as if he had seen them somewhere before.

Until daybreak.

Throughout the entire locked room, only the blind old man's voice could be heard.

That night, he couldn't remember exactly how many kinds of herbs he had identified, but he was a herb fanatic. He was so excited to be able to come into contact with so many herbs again after going blind that he forgot his fear. After he finished, he asked, "Is there any more? If there is, let me smell them again. I recognize eight or nine out of ten herbs in the world."

After Wuhen helped him away, Ji Fengyao asked curiously with a smile, "Black Owl, where did you get this old man? He seems quite knowledgeable about herbs, and he's a rather interesting person."

Are you somewhat familiar with me?

Black Owl was speechless: "Your Highness, he is Qiu Haikun, the most sought-after imperial physician in the previous dynasty's palace."

Shang Xiye's originally lowered eyelids twitched slightly. It turned out to be Qiu Haikun, who was known as the first imperial physician of the previous dynasty. It was said that the Qiu family's ancestors were apprenticed to the Sage of Medicine.

Black Owl knew Qiu Haikun, but why did Black Owl never mention him when he was poisoned?

"Are all the ingredients for the antidote ready?" Shang Xiye looked up at Ji Fengyao.

Ji Fengyao skillfully and accurately took down six boxes from the two large wooden shelves behind her, which were filled to the brim: "No need to worry, it's a very simple poison, there are hundreds of antidotes, and the medicinal materials are easy to gather. These are all."

The antidote only requires six medicinal ingredients?!

Shang Xiye recalled the dozens of formulas and antidotes that Sun Shouli had mentioned yesterday, and fell into a deep silence...

Wuhen went out, and Hei Xiao seemed to disobey Shang Xiye's discipline.

Ji Fengyao piled the medicine box she was holding onto Shang Xiye's lap, made him hold it, stretched, and said sleepily, "Here, I'm so sleepy. Let's wash up and catch up on sleep. Hei Xiao, you've been working hard all night, you should go back and catch up on sleep too." Then she pushed Shang Xiye towards the secret passage they had come from the previous night.
