Seeing Lin Yuemin wake up, the middle-aged man's eyes flashed with tears, and then he handed Luofu Cao into Zhao Ping'an's hands very simply.

Zhao Ping'an nodded and asked the person in charge of Huasheng Hall to plant the herbs.

Lin Yuemin looked at the ceiling incredulously, not imagining that he would wake up one day.

"You...... Hiss. As soon as Lin Yuemin pronounced a word, he gasped in pain.

Zhao Ping'an smiled and said: "The medicine must be at a high temperature, don't worry about the bubbles on your mouth, I'll get you some medicine in a while, and it'll be fine if you put it on." ”

Lin Yuemin moved his head up and down sluggishly, but still didn't react.

Zhao Ping'an stood up and said to the two: "Let the patient recuperate, he can't eat for three days, and if he has any difficulties, go to Huashengtang." ”

The middle-aged man gratefully sent Zhao Ping'an away all the way, and then hurried back to take care of Lin Yuemin.

Zhao Ping'an thought as he walked, the person who was dealing with Xinglintang behind his back definitely had a deep background, and he was able to bring down a Xinglintang, it is estimated that Huashengtang was also a thorn in his side, and this matter must be vigilant.

After explaining this matter to everyone in Huashengtang, Zhao Ping'an found the Luofu grass that had been planted, in the simulated frost environment, the Luofu grass had become much more energetic, Zhao Ping'an picked off the "cang'er" on its leaves, and returned to his research room in the villa.

The recipes of Luofu grass and incinerant grass, Zhao Ping'an has simulated it many times in his heart, and the formula is already very mature, and Zhao Ping'an made more than a dozen round pills at one time.

Zhao Ping'an watched his results, and then looked at today's date, it has been half a month since the last time he went to Cheng's house, and now it is time to go to review.

Zhao Ping'an came to Cheng's house, just happened to meet Cheng Hong who was going out, Cheng Hong patted his head after seeing Zhao Ping'an and said: "Doctor Zhao, this is a coincidence, I was planning to go to Dr. Sun to find you." ”

Zhao Ping'an nodded and followed Cheng Hong to the old lady's room.

The old lady's spirit was much better, but it was still much worse than normal, and she was out of breath when she got up from the bed to say hello.

Zhao Ping'an hurriedly asked Mrs. Cheng to lie down, and then took out two pills of medicine and handed them to Mrs. Cheng.

"I won't hide it from you, this drug was just developed by me, and it hasn't been clinically tested yet, I think it's safe, but I still want to tell you, if you don't feel at ease, you can also use it, I don't think the old lady is in a big deal except for physical weakness." ”

When Cheng Hong heard this, he really hesitated a little and asked, "Then if you don't use medicine, will it have any effect?"

Zhao Ping'an thought for a while and said, "It will have a certain impact on Shouyuan." ”

At this time, Cheng Hong had not yet spoken, and the old lady said with a firm face: "It's okay, I believe in you." ”

At the request of Mrs. Cheng, Zhao Ping'an put the pill in the old lady's hand, and the old lady swallowed it very decisively.

After taking the medicine, the old lady's face just became a lot more ruddy, but there was no adverse reaction, Cheng Hong and Zhao Ping'an stared intently for half an hour, and found that there was really nothing, Cheng Hong was relieved and thanked Zhao Ping'an.

At this time, Zhao Ping'an suddenly thought that the people who could know about the burning flame grass and use it would definitely not be able to make a double ten, and perhaps, the person who murdered Xinglintang and the person who murdered Mrs. Cheng might have something to do with it.

"Have you found the person behind the scenes?" Zhao Ping'an asked Cheng Hong.

Cheng Hong shook his head helplessly: "I found out that it was done by a housekeeper who has worked in my house for more than 20 years, but I know that the housekeeper is a medicine blind who can't even distinguish between ginseng and Ganoderma lucidum, so there must be someone behind him, and when I wanted to ask, the housekeeper died." ”

Zhao Ping'an's heart was cold, the housekeeper actually died, and the people behind this scene were really ruthless.

"Where is the body, take me over to see, why did he murder the old lady, did he have some tricks caught?"

Cheng Hong then shook his head, indicating that he didn't know anything.

The housekeeper's body had not yet been disposed of, Zhao Ping'an followed Cheng Hong to a cold room, and as soon as he entered, Zhao Ping'an's hair and eyebrows were covered with a layer of hoarfrost.

Cheng Hong sighed in his hand, and with a hard pull, a huge drawer was opened, bleeding from seven orifices, and a blue face appeared in front of Zhao Ping'an.

Cheng Hong couldn't accept such a cold environment and the scary appearance of the housekeeper, Zhao Ping'an was very considerate and let Cheng Hong leave and observe the corpse by himself.

The corpse was dumbfounded, and his sloppy eyes looked straight up, Zhao Ping'an lowered his head and carefully observed the butler's pupils.

There was once a saying that after a person is killed, he will leave the mark of the last thing he sees in his pupils, although this sounds very unreliable, but Zhao Ping'an knows that the eyes of the corpse can expose a lot of things.

The cause of the housekeeper's death was very simple, cyanide poisoning, and there was a faint smell of bitter almonds around his mouth, but this obvious discovery did not satisfy Zhao Ping'an.

Zhao Ping'an looked at the housekeeper's body, the whole body was naked, and on the inside of the wrist, there was a needle eye that was not easy to find.

The blue around the eye of this needle can prove that the person who injected the medicine to the housekeeper is a layman, who should have not studied Chinese medicine or Western medicine, and does not know how to inject or use silver needles. Continuing to look down, a certain part of the butler was still in a state of standing, lying in the freezer for several days, and the chickens were so frozen that a trace of drying up could be seen.

Zhao Ping'an took a little bit and put it in the evidence bag he brought before, ready to go back to find a place to do a test.

If the butler had done piston exercises before he died, the person who exercised with him might be the murderer.

Zhao Ping'an turned the housekeeper over, looked at the front and looked at the back, but to Zhao Ping'an's disappointment, even the chrysanthemums were checked, but no more were found.

Zhao Ping'an put the housekeeper back in place, then put it back in the freezer and walked out of the refrigerator.

After a few simple explanations to Cheng Hong, Zhao Ping'an threw the evidence bag to Cheng Hong, and hurriedly went home to take a shower and smeared some medicine for frostbite.

In less than a day, the results of the examination came out, and as Zhao Ping'an expected, the traces on the housekeeper's body were indeed left by a woman, but after a long time of placement and low temperature, it was difficult to detect DNA, and it could only be compared with a little bit, which was a matter of time.

Leave this matter to Cheng Hong to do, Zhao Ping'an didn't care too much, and once again told the people of Huashengtang to pay more attention, and take care of Lin Yuemin by the way.

After a day of reviewing medical books at home, Zhao Ping'an ushered in the start of school again.

The first class in the afternoon was Zhao Ping'an's class, Zhao Ping'an came to the classroom five minutes early, the classroom was already full, in addition to the students in his class, there were many people from other classes who came to watch the handsome teacher, and most of them were girls.

Zhao Ping'an didn't blast them out, and finished a class by himself.

After class, Chen Ming came over and stopped Zhao Ping'an again, one to apologize, and the other to express gratitude.

Zhao Ping'an didn't say anything, just gave Chen Ming a pulse, and found that the deepest snake venom in his body had not been cleared, so he simply took out the remaining pill in his pocket, divided it into a quarter, and handed it to Chen Ming.

"This medicine is strong, the snake venom in your body is almost cleaned up, you only need to eat a quarter. ”

Chen Ming nodded again and again and swallowed it in one go.

After letting Chen Ming finish taking the medicine, Zhao Ping'an returned to his office and found that in addition to his old colleagues in the office, there was also a shiny bald head.

This bald head is Principal Zhang Zhiying, and Sun Henian, who is still a little impatient, is sitting next to him.

"Uncle Shi is out of class, Lao Zhang came over to ask you to help take a look at your body, if it's inconvenient, just refuse, don't give me face." Sun Henian was the first to speak, and Zhang Zhiying gave Sun Henian an elbow behind Sun Henian's back and pushed him away.

Zhao Ping'an nodded and said casually: "It's okay, you stretch your wrist over, and I'll take the pulse." ”

Zhang Zhiying and Zhao Ping'an sat facing each other, putting their left hand on the wrist pillow, Zhao Heping lowered his eyes, and it took nearly a minute before he finally spoke: "Have you eaten something hot recently?"

Zhang Zhiying nodded hurriedly and said, "Yes, I had dinner two days ago and ate a lot of mutton. I've been feeling burning all over my body for the past two days, and I have a big ulcer in my mouth, and I want you to prescribe me a recipe to reduce the fire. ”

Zhao Ping'an shook his head and said: "The heat of mutton is negligible to you, but the meridians in your body have a slight burn, maybe it is because of taking strong medicine that it will cause this." ”

Zhang Zhiying was shocked: "I haven't taken any medicine recently, it's impossible." ”

Zhao Ping'an asked Zhang Zhiying to change his hand, the pulse in his right hand was more obvious than his left hand, and there was a hot breath between the pulses.

"I'm a doctor myself, I know if I take medicine or not, but what's going on?" Zhang Zhiying scratched the back of his head, puzzled.

Zhao Ping'an's face was solemn, could it be that Zhang Zhiying was also secretly drugged?

It's not impossible.

Zhao Ping'an called a group of old men around him, checked their pulses one by one, and found that except for Sun Henian, these old men all had hot and dry pulses without exception.

Zhao Heping asked Sun Henian what was the difference between him and these old men, Sun Henian thought for a long time, and then said that it might be that he ate with his granddaughter every day, so he didn't go to the school's staff cafeteria much, so it caused these abnormalities.

Could it be that someone poisoned the cafeteria? Zhang Zhiying's face was solemn, if this was the case, he, as the principal, must thoroughly investigate.

Zhao Ping'an asked Zhang Zhiying to call a few teachers from other departments over and check their pulse one by one.
