After rebirth, she became the favorite of the powerful minister.

Even though Yuan Ge thought about this problem for a long time, he still couldn't figure it out.

Back at the herb garden, I saw Feng Qingtan, who was almost completely crouched in a pile of herbs. He looked up from among the herbs upon hearing the noise, and then, without surprise, waved, "Little Ge'er, come here, let me show you something."

The tone was somewhat excited.

It seems to have swept away the gloom of the past few days.

Yuan Ge approached and discovered several old books spread out at his feet. The pages were yellowed, and some seemed to have been torn out and were crookedly stuck in the books. She sorted them out casually and found that most of the pages were notes written by the old man. The handwriting was small and dense, and the pages were bound one by one between the books - a book she had never seen before.

Feng Qingtan glanced at the obvious hesitation on her face, then smiled, not hiding anything. "These are some things I sorted out years ago. I had put them in a corner and forgot about them. I only found them this morning while browsing ancient books... They weren't common things, but the old man's illness seems really strange to me. The symptoms are different for each person. It doesn't look like an illness, a poison, or the kind of Gu that makes people shudder. It seems more like... some kind of hint."

Yuan Ge was slightly stunned and subconsciously asked, "Implication?"

"Yes, suggestion, or... illusion." Feng Qingtan took the patched old book from Yuan Ge and flipped through it carefully. The yellowed pages rustled under his fingers, as if they could be crushed to dust at any moment. He turned the pages very carefully, but also very familiarly. In the blink of an eye, he turned to the page that needed to be read and handed it to Yuan Ge. "I have been practicing medicine for half my life. If it is the same disease, the symptoms are generally the same. But this time is different. Your grandfather is hot and cold, and the people in the second brother's room are suffering from headaches, chest tightness, and nightmares. In the past two days, several completely different symptoms have appeared."

"Besides, the old man's condition should have gotten worse over the past few days, but I haven't noticed... Looking at all these signs, I feel it's quite strange. I just remembered the symptoms I sorted out earlier... Look, this."

The place where the old man pointed his finger was densely covered with comments. The characters were small but extremely neat, written in extremely careful small regular script. Under the comments were four words that were almost covered up - luxuriant and fragrant.

The old man's handwriting was different from Yuan Ge's. Yuan Ge's was fierce and unrestrained, his edge unflinching and fearless, while the old man's was cautious and prudent. The old man always said that medical practitioners must be extremely cautious and not be careless, and certainly not be lazy and arrogant because of their experience. So even though the old man had a bad temper and was difficult to deal with, he was extremely serious and cautious at heart. He had practiced medicine for most of his life and had never made a mistake.

The name of the miracle doctor spread.

But before this fame reached its peak, it suddenly came to an end - the miracle doctor Feng Qingtan disappeared.

Not long after, an unkempt, eccentric old man appeared on Zhixuan Mountain. This old man didn't like going out or seeing people. It was rumored that he planted poisonous weeds and raised poisonous insects in his medicine garden. What's more, there were rumors that a new maid on Zhixuan Mountain didn't know the rules. When she passed by the medicine garden gate, she stayed for a moment and fell into a deep sleep. She died within two days... As rumors spread, the medicine garden became a dangerous place that everyone avoided.

Feng Qingtan also allowed the rumors to spread without explanation, thus shielding him from prying, curious eyes. As a result, few people knew that the plants planted in the medicine garden were rare treasures in the world... The old man wished he could hold them in his arms and care for them day and night.

Yuan Ge followed the direction of the old man's finger, scanning the strange-looking herb. Its leaves were slender, slightly curled at the tips, verdant with distinct veins. Strange barbs grew along the edges, and a touch of his fingertip felt like the prick of an embroidery needle, a prick that felt like a direct connection to the heart. At the tip of the herb grew small, dark red fruits, clustered in groups of four or five. Their deep crimson color was inexplicably strange and eerie.

The name of this grass is "Wei Rui". According to records in books, it mostly grows beside mountain streams.

That being said, Yuan Ge had spent years collecting herbs in the mountains, but he had never encountered a wild weirui. Rumor has it that this herb emits a strange fragrance at midnight, attracting nearby birds and beasts to a frenzy to feast on it. However, the old man had chanced upon such a plant many years ago, and after carefully nurturing it for several years, he finally saw these small fruits. They weren't particularly impressive, but upon closer inspection, their dark, bloody color was eerie and creepy.

"Wei Rui Sheng Xiang" is a poison that is not fatal but hallucinogenic. The illusory pain can torture people to the point of death. It is a very vicious poison, but it is extremely rare because the herbs are hard to find and the preparation process is complicated. Wei Rui is both a poison and an antidote. The poison is made from Wei Rui leaves and the antidote is made from Wei Rui fruits. If it is just to give the opponent the illusion that it is difficult to escape, it is really too much trouble, so this poison is almost lost.

After wandering in the fog for many days, the thick fog finally dissipated, and the answer lay before her eyes. However, Yuan Ge suddenly found it a little hard to believe. She blinked, glanced at the fruit-bearing sedge in front of her, and then looked at the handwriting that was almost covered by the dense annotations. After a while, she finally found the almost disappeared voice. She tilted her head to look at the old man and asked in a dry voice, "In front of... like this?"

The fingertips dug into the palms, and the ending notes had a tremolo, which was an obvious anticipation.

The old man tilted his head to look at her, surprised at the little girl's unusual caution. With a slight sigh in his heart, he raised his hand to touch Yuan Ge's head, but in the end he just shook his head. He hesitated for a long time with a gloomy expression before saying, "Although this thing has not been lost, I have been practicing medicine for most of my life and have never seen such a poison. So now I am only suspicious and cannot be sure... Most importantly, I haven't figured out where this poison came from or how it was administered. This thing called Wei Rui Sheng Xiang is not easy to deal with."

"I haven't seen it in ages, and there aren't many records. I've been searching for half a day now, and I found the last very convincing record from a hundred years ago. It said a great general won a great victory in reconquering the Wu Clan in the Western Regions, and upon returning home, he developed hysteria. The doctors initially thought it was just hysteria, but when the same symptoms appeared in the palace one after another, they realized something was wrong... However, it was too late. The entire general's mansion was almost wiped out, and even the royal family was affected, with a prince who had just turned sixteen dead. The emperor was furious and ordered a thorough investigation. The entire Wu Clan was wiped out overnight... History calls it the Wei Rui Disaster."
