On the first day that Yin Heng was invited to enter the Zhaoguo Imperial Palace as a pharmacist, Li Pei, the emperor of Zhaoguo, showed him the prescription that had put the first emperor to death, and asked him if he had really practiced this medicine with his master Guan Hermit.

After reading the prescription, Yin Heng generously admitted: "This prescription has been made by the grass people and the master, and the grass people are present during the whole process. ”

Li Pei stared at him closely, and could see that he was not lying, so he asked again, "Did your master say why he made this medicine at that time?"

"Nope. ”

"What are the properties of this medicine?"

"Each of the drugs in it is highly toxic, and it only takes a little to kill people when it adds up, and it is not easy to find out the source of the disease. ”

Li Pei's eyes turned red and asked, "Will it be painful when you die?"

Yin Heng replied: "This grass man doesn't know, the grass man has not experienced it, and he has not seen others experience it. ”

"Okay. Li Pei sighed, and then said, "Can you restore your master's performance in the two or three days before his death? ”

Yin Heng nodded and said, "One afternoon, the master who had gone out for a walk came back to the house and told me that he was going to refine a medicine, and said that he might have to refine it all night, and asked the grass people to help. Knowing that there was another medicine to be refined, the grass people were very happy, but when the grass people saw the prescription, they froze and hurriedly asked the master why he wanted to refine this highly poisonous medicine. Master just smiled and didn't answer. The grass people then tried several times, but the master was always tight-lipped, and the grass people understood the master's personality, and knew that the master would never use it to harm others even if he practiced such medicine, so he didn't ask again.

We practiced until the end of the ugly time, and then Master carefully put the medicine in the cabinet and locked it before going to sleep.

The next day, Master said that he was going to meet alone, and after breakfast, he hurried down the mountain. When he returned, the grass people asked him if he had a name for the medicine he had refined last night, and he said that he had not yet, saying that he would wait for him to think about it, but he didn't mention it again after that, and it seemed that he didn't want to continue to dwell on the problem. The next day, the grass people went down the mountain to buy rice, oil, salt, sauce, vinegar and other things, and came back before the sun turned west, but when they got home, they found that the steamed buns on the table were left there unmoving, and the master could not be found in the room. The grass people immediately went outside the house to look for it, and soon found it. At that time, the master had already lost his breath, and there were knife marks on his chest and neck, and blood was flowing all over the ground. ”

When he said this, Yin Heng's tears burst out of his eyes.

Li Pei handed him a small handkerchief.

Yin Heng wiped away his tears and continued: "The grass people immediately found the key to open the cabinet where the master specially stored important medicines, and found that the bottle of medicine that was refined the day before yesterday was missing, and then the grass people searched all over the house, but there was no trace of the bottle of medicine, so he guessed that the master should have handed over the bottle of medicine to the person who made an appointment to meet him.

The grass people buried the master in the place where he was killed, put a stone on it to mark, and then went down the mountain to look for the person who had made an appointment with the master yesterday, but the grass people searched for nearly half a month and did not find it, so they returned to their residence. Nearly a year later, the grass people saw Gu Bainiang, who was also looking for the murderer, and the people from the 'Sun Moon Meteor Knife' faction, so they had some friendship with them, so after learning the news of Jiang Xiaogongzi's assassination this time, Gu Shiban Niang invited the grass people to come with him, and there was also an opportunity to meet with Your Majesty, and this is how it happened. ”

"I want you to refine an identical medicine again, can you do it?" Li Pei asked.

Yin Heng hurriedly waved his hand and said: "It's not a secret, the grass people were also the master's helpers at that time, and the main operation was still from the master, so what is the amount of each medicine, and the heat of which step is a little different, these details are not very complete for the grass people." ”

Li Pei said: "You can first refine a pair according to what you remember." ”

Yin Heng asked a little uneasily: "What does Your Majesty want to do with it?" After all, this is a highly poisonous thing, and if you are not careful, you will die." ”

Li Pei replied calmly: "I know that after refining at that time, I will take good care of it, and I will not let idle people have a chance to touch it." ”

Yin Heng said very embarrassed: "There are several medicinal materials that are difficult to find, but I am afraid of ......."

Li Pei said: "All the medicinal materials needed here have been prepared. ”

After that, he asked his personal father-in-law to present the medicinal materials for this dose of medicine.

Yin Heng had no excuse now, so he had to nod and agree.

At noon that day, Yin Heng refined this medicine, and did not refine it until the dead of night, and then hurriedly handed it over to Li Pei's hands.

Li Pei sent someone to use it on the rat the next day.

Sure enough, the rat struggled and ran out of breath.

Li Pei conveniently summoned a group of old ministers and important ministers to a meeting that afternoon. During the meeting, he put the bottle of medicine on the table and said, "This medicine is the medicine that put the emperor to death back then, and I have found out who the refiner is." ”

Sima Yu, who was present, suddenly chuckled, and immediately looked at the bottle of medicine with vigilance.

The medicine was contained in a transparent bottle, slightly green, the bottle was not large, and the powder was only half a bottle, which was obviously not a large amount. However, the toxicity of this drug is high, so just a little bit is enough to kill a dozen or twenty people on the spot.

Sima Yu had seen this medicine back then, so now he couldn't help but change his face when he saw it.

In this way, the emperor has recently made a new discovery about this case? Sima Yu unconsciously became apprehensive.

Li Pei's eyes quietly glanced at the ministers present, and soon noticed the strangeness of Sima Yu's expression, and his heart suddenly felt a little bottom, looking at everyone solemnly and said: "Now, I have found the only disciple of Guan Hermit......"
