I am the Holy Poisoner, the Empress advised me to calm down

"What's the situation in the hospital now?" Lin Feng asked.

"The nurses are afraid to work the night shift, and they have to take turns working during the day. Many have resigned. If this continues, the hospital will close." Zhao Minghui sighed, "My father told me to solve this problem no matter what, or I can't go home."

After driving for three hours, they finally arrived in the provincial capital. The Zhao family's rehabilitation hospital, a modern, twelve-story building located in the city center, looked ordinary from the outside. But as they entered the hospital lobby, Lin Feng immediately sensed a depressing atmosphere.

There were almost no patients in the hall, only a few nurses chatting quietly at the duty desk. When they saw Zhao Minghui come in, their expressions were a little nervous.

"Mr. Zhao, you're back." An elderly head nurse came over. "We've already reported last night's situation. There are only a dozen or so patients left in the inpatient department. The others have requested transfer or discharge."

"I see." Zhao Minghui nodded, then introduced Lin Feng, "This is Doctor Lin, who is here to solve the problems in our hospital."

The head nurse glanced at Lin Feng, a hint of doubt in her eyes. Could such a young doctor solve such a strange problem?

"Take me to see those patients first." Lin Feng said directly.

They took the elevator to the inpatient department on the eighth floor. The corridor was unusually quiet, with only the occasional whisper from the wards. Lin Feng noticed that the lights in many wards were on, even during the day.

“The patients are now afraid to sleep with the lights off,” the head nurse explained. “They say they can see strange things in the dark.”

In the first ward was a man in his fifties recovering from a cholecystectomy. He sat up nervously when he saw someone come in.

"Is it coming again? Is it coming again?" His eyes were filled with fear as he kept looking towards the corner of the ward. "It's right there, staring at me!"

Lin Feng walked to his bedside and placed his hand on his pulse. The pulse was rapid and irregular, but what concerned Lin Feng even more was that he could smell a faint, peculiar odor from the patient, like some kind of fungus.

"Have you eaten any special food recently?" Lin Feng asked.

The patient was stunned for a moment. "No, it's just hospital food. But the nurse gives us a nutritious soup every day, saying it can help wounds heal."

Lin Feng and Zhao Minghui exchanged a glance: "When did this nutritious soup start being provided?"

"About a month ago," the head nurse replied. "Our new head of nutrition recommended it. They said it uses the latest nutritional formula."

“Where is the ingredient list for the recipe?”

"It's in the nutrition department. I'll have someone bring it to you right away."

Lin Feng examined several more patients and found that they all had similar symptoms: slightly dilated pupils, flushed skin, irregular pulses, and a distinctive odor. More importantly, they had all consumed the so-called nutritious soup within the past month.

Soon, the nutrition department brought the formula list. Lin Feng looked through it carefully. Most of them were common nutrients, but there were a few herbal ingredients that made him frown.

"What is this 'Gastrodia Essence'?" Lin Feng asked, pointing to an item on the list.

"This is what we purchased from a new supplier. They say it's pure, naturally extracted Gastrodia elata essence, which has a very good effect on the recovery of the nervous system." The director of the nutrition department is a female doctor in her forties who looks very professional.

“Where’s the supplier’s information?”

"It's in the purchasing department. I'll get it."

After she left, Lin Feng said to Zhao Minghui, "The problem might be with this Gastrodia elata essence. Real Gastrodia elata wouldn't cause these symptoms, but if it's some other fungus impersonating it..."

"Are you saying someone poisoned you on purpose?" Zhao Minghui's face turned ashen.

"It's very likely. And this method is very professional. The toxin chosen is not immediately fatal, but it will cause persistent hallucinations and mental symptoms, making people think it is a supernatural phenomenon."

At this time, the head of the nutrition department returned with a document in his hand. "This is the supplier's information. It's called the 'Natural Herbal Medicine Research Institute' and its registered address is in an industrial park in the suburbs."

Lin Feng looked at the company's information. The company had only been registered for six months, and the legal representative was an unfamiliar name. "How did you find this supplier?"

"They contacted us on their own initiative. The samples they provided were very effective and the price was much cheaper than the market price, so we..." The director of the nutrition department's voice gradually faded away.

"Stop using all products from this company immediately!" Lin Feng said seriously, "and seal up the remaining samples. I need to conduct detailed testing."

"But what about the patient's nutritional supplements?"

"Use regular nutrient solution for now." Lin Feng turned to Zhao Minghui, "Does your hospital have a laboratory?"

“Yes, the equipment is quite complete.”

"Okay, I need to analyze these samples. Also, you need to immediately investigate the background of this supplier. I suspect this isn't a simple case of commercial fraud."

That afternoon, Lin Feng was busy in the hospital laboratory. Through microscopic observation and chemical analysis, he finally confirmed his suspicions: the so-called "Gastrodia elata extract" contained a large amount of hallucinogenic mushroom extract, the main components of which were psilocybin and dephosphorylated psilocybin.

These substances can cause strong visual and auditory hallucinations, and long-term use can lead to mental instability and cognitive impairment. What's more frightening is that the metabolism of this toxin in the body is very slow, and even if you stop taking it, the symptoms will persist for a period of time.

"We've found the problem." Lin Feng handed the test report to Zhao Minghui. "Your patient was poisoned, not haunted by a ghost."

Zhao Minghui's face turned grim as he read the report. "This natural herbal medicine research institute actually poisoned our nutrient soup! This is killing us!"

"The question now is, why do this?" Lin Feng pondered. "If it was just for the money, there would be no need to use such complicated methods. Moreover, the preparation of this toxin requires considerable professional knowledge, which is not something that ordinary people can do."

"what do you mean……"

"Someone wants to destroy your hospital, and this person has a deep hatred for your family." Lin Feng looked at Zhao Minghui, "Has your family offended anyone recently?"

Zhao Minghui frowned and thought for a moment: "How can you do business without offending people? But if there's a deep hatred..."

He suddenly stopped, his face turning pale: "Could it be...that thing five years ago?"

"What's the matter?" Lin Feng noticed the change in Zhao Minghui's mood.
