Ye Mengchen's dorm had a private bathroom, so after Yan Mei and Zhao Wan heard Ye Mengchen's words, they helped him enter the bathroom on her left and right.

Chen Hui already had a certain amount of judgment in his heart, and his eyebrows furrowed even more tightly.

Because Ye Mengchen's situation didn't look like she had been poisoned by food, but more like she had been poisoned by senna leaf.

The source of the leaves is the legume of the leguminous plant, or the leaf of the sharp leaf, which is an irritant purgative. It is a fierce drug which is stimulated by the intestinal mucosa and nerves, and is generally recommended by the doctors to use it as little as possible.

The personality of the senna leaf: Sweet, bitter, cold, has a small poison.

If one took too much senna leaf medicine, they would be poisoned.

After poisoning, nausea, vomiting, bowel sounds, abdominal pain, diarrhea, dizziness, wobbly walking, unsteady standing, numbness in the face and limbs of the mouth and lips, itchiness in the tip of the nose, itching in the opening of the urethra, filling of the bladder, no sensation of urination, swelling of the fingers, dilated pupils, flushing of the face, fear of food, rising body temperature, and accelerated breathing.

Epilepsy may sometimes occur, manifested as shortness of breath, spasms of limbs, delirium, fists made with both hands, teeth closed, eyes up, foaming at the mouth, unconscious.

Ye Mengchen's current symptoms had not reached the degree of being severe enough to cause an epileptic seizure, but the symptoms she displayed were exactly the same as the senna leaf's mild poisoning.

Chen Hui was currently waiting for Ye Mengchen to come out. He only needed to determine the color of Ye Mengchen's after diarrhea to make a full diagnosis.

senna leaf was a strong medicine among the laxatives, even the doctors would recommend to use it as little as possible, only when the cafeteria was crazy would senna leaf be added to the food!

If Ye Mengchen was really poisoned by the senna leaf, that could only mean one thing. The matter of the students being poisoned, was basically deliberately poisoned, and it was not food poisoning at all.

"How is it? Chen Hui, can you cure it? " Former Principal Chen Hong asked with an anxious expression.

Chen Hui nodded his head, and said: "I still need a few more conditions to make a diagnosis, as long as it is easy to treat."

Chen Hui said that it would be easy to treat, not easy to treat. This made Chen Hong feel relieved.

At this time, Ye Mengchen walked out with the support of Yan Mei and Zhao Wan, and sat back in her own chair. This kind of plan to get off the bed had a drawback at this time, and it was that Ye Mengchen was currently in a state where she couldn't climb out of bed at all. Even if she had the strength to get into bed, it was impossible for him to get into bed at all, because it was very inconvenient for her to run to the toilet from time to time.

Chen Hui immediately asked softly: "Is the diarrhea black?"

Ye Mengchen frowned and nodded, but did not say anything.

At this point in time, Chen Hui had already confirmed. Ye Mengchen was poisoned by senna leaf, not food poisoning.

If the senna leaf was poisoned lightly, then it would show symptoms similar to food poisoning, which would easily lead the doctor to the wrong diagnosis. The only difference was the color of the diarrhea, the diarrhea from the food poisoning might not be black, but the diarrhea from the senna leaf would definitely be black.

Chen Hui came over from the boys' dormitory. At the beginning, Chen Hui had thought that the boys had been poisoned due to the food, so he hadn't thought about it at all, because the symptoms that the boys in the boys' dormitory had were completely light symptoms of the senna leaf's poison. It wasn't any different from the food poisoning.

Ye Mengchen's senna leaf poisoning situation was clearly more serious than the other students', showing symptoms unique to senna leaf poisoning, such as shortness of breath. Only then did Chen Hui become suspicious and he began to judge the direction in which the senna leaf had been poisoned.

"Is there any egg white or milk?" Chen Hui asked at this time.

"There's milk!" Yan Mei immediately replied.

"Give her milk." As Chen Hui spoke, he took out the silver needles and a small bottle of alcohol. After disinfection the needles with alcohol, he asked, "Is there fire?"

Chen Hong immediately reached into his pocket and took out a lighter, giving it to Chen Hui.

Chen Hui took the fire machine and adjusted the size of the fire. He then used the fire to heat up the silver needles and said to Ye Mengchen: "Raise your left arm!"

After Ye Mengchen erected his left arm, Chen Hui immediately used this silver needle that had been heated up before to insert into Ye Mengchen's intestines. Then, using the same method, she pierced into the liver and heart acupoints on Ye Mengchen's left arm, using the silver needle that had been heated up.

Three needles that had been added in, after piercing through Ye Mengchen's intestines, liver, and heart, the effects were immediately apparent. Ye Mengchen's nausea, vomiting, unbearable pain in her abdomen, and the symptoms of diarrhea, had all disappeared!

At this time, Ye Mengchen had already finished her carton of milk, and her entire state of mind was different from before.

"It's that magical?" Yan Mei and Zhao Wan widened their eyes and said with an expression of disbelief.

Jiang Jingxiu actually asked at this time, "Is this a fire needle technique?"

The fire needle was a way to use the burning red needle tip to quickly pierce the acupoint and cure the disease.

This acupuncture technique has the function of warming meridian and dispersing cold, activating meridian and so on, so it is used in clinical treatment of deficiency cold and so on.

senna leaf's nature was cold, and the fire needle technique was just right.

Even though acupuncture techniques were known by all Chinese doctors, it required an extremely high level of medical skill to use a burning red needle. Thus, there were very few people who were able to use this kind of acupuncture techniques.

Chen Hui nodded his head and explained to Jiang Jingxiu: "The fire needle technique is one of the right diseases, and the other are the three acupoints, namely the intestines, the liver, and the heart. This hand of mine is called the three gates of the fire needle.

"Now is not the time to discuss medicine. Since your three fire needles have miraculous effects, shouldn't you hurry up and treat the other students?" Chen Hong immediately said.

Chen Hui slowly shook his head and said: "It's not that I don't want to treat it, but this matter is fraught with doubts, and there are still a lot of things that still needs to be confirmed. Moreover, because Ye Mengchen's symptoms are serious, she needs the three treatment methods of the Fire Needle.

"What do we do now?" Chen Hong asked with an anxious face: "What exactly do you want to confirm?"

"I'm sorry, Old President. I can't tell you." Chen Hui sincerely said to the old Principal: "However, I can provide you with a prescription. For students who can't make it to the hospital in time, using this prescription should be effective."

"Then what are you waiting for? Hurry up and give me the prescription." Chen Hong said snappily: I wish I could kick you twice!

"The soup won't simmer well for the time being. First, let the ones who are sick drink the egg white or the milk to protect the gastric mucosa." Chen Hui immediately said: "Use a large amount of raw ground elm, add the Mausoleum Cuisine, licorice root to make the soup, the ratio is 9 to 6!"
