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

Zhao Jianguo excitedly shook Lin Fan's hand. "Doctor Lin, you are truly our savior! Now that the patient has recovered, the reputation of our hospital can be restored."

"Don't be too happy too soon." Lin Fan's expression turned serious. "Although the patient has recovered temporarily, the toxin has not been completely eliminated. And more importantly, you must find the source of the toxin, otherwise this will happen again."

"Where's the source of the toxin?" Zhao Zhiqiang asked doubtfully, "Could it be that there's something wrong with the hospital's food or water?"

Lin Fan shook his head. "This method of poisoning is very targeted and the technique is very professional. This isn't an accident; someone did it on purpose."

"Intentional?" Zhao Jianguo's face changed drastically. "You mean someone wants to harm us?"

"It's not just about harming you," Lin Fan analyzed. "The extraction and use of this poisonous mushroom is a traditional skill of certain ethnic minorities, usually used for revenge or punishment."

The atmosphere in the ward suddenly became tense.

"Revenge?" Zhao Zhiqiang swallowed, "Did our family offend anyone?"

"Only you two know this." Lin Fan looked at the father and son. "Think about whether you've had any conflicts with anyone recently, especially those involving ethnic minorities."

Zhao Jianguo and Zhao Zhiqiang looked at each other, trying hard to recall.

"Oh right!" Zhao Zhiqiang suddenly remembered something. "Some time ago, there was a patient who seemed to be from the Miao ethnic group. He had a very unhappy relationship with her because of a medical dispute."

"What medical dispute?" Lin Fan asked.

"The patient's daughter had surgery in our hospital, and the result..." Zhao Jianguo hesitated to speak.

"what's the result?"

"The operation failed, and the patient died on the operating table," Zhao Zhiqiang whispered. "The Miao elder demanded our lives and threatened to make our entire family suffer."

"How did you handle it then?"

"We paid some money and admitted the medical malpractice, but the old man refused to give up. In the end, we had to suppress the matter through connections," Zhao Jianguo said with some guilt.

Lin Fan sneered, "You think you can just give a little money and it'll be over? The Miao people take blood feuds very seriously. His daughter is dead, how could he let it go so easily?"

"What should we do now?" Zhao Zhiqiang panicked. "We can't find that old man at all, and even if we do find him, what can we do?"

"We must find him and resolve this issue face to face," Lin Fan said. "Otherwise, he'll find ways to retaliate against you. Next time, it might not just be about causing hallucinations in a few patients."

Zhao Jianguo's forehead broke out in sweat: "Doctor Lin, do you have any solution?"

"I need time to prepare an antidote to completely remove the toxins from these patients. Meanwhile, you must find a way to find that Miao elder." Lin Fan pondered for a moment. "Also, I suggest you temporarily stop accepting new patients and conduct a comprehensive inspection of the hospital to determine the specific method and location of the poisoning."

"Well..." Zhao Jianguo was a little embarrassed. "If we stop operating, the losses will be huge."

"Compared to the lives of your entire family, what is money?" Lin Fan said bluntly.

Just then, the head nurse rushed in: "Director, this is bad! Three more patients have developed similar symptoms!"

Everyone's faces turned pale in an instant.

"It seems the old man hasn't stopped yet." Lin Fan stood up. "Now is not the time to discuss the losses. We must act immediately."

"Doctor Lin, if you can help us solve this problem, I'm willing to give you some of the hospital's shares," Zhao Jianguo said sincerely. "Please save us."

Lin Fan looked at the panicked father and son before him and shook his head inwardly. This was the so-called karma. There was always a price to pay for wrongdoing.

"No need for shares, but I have a condition." Lin Fan said.

"What conditions? Just tell me!"

"Once you find the Miao elder, you must sincerely apologize to him and compensate him according to Miao customs."

"No problem, absolutely no problem!" Zhao Jianguo nodded repeatedly.

Lin Fan nodded. "Okay, let's split up now. I'll prepare the ingredients for the antidote, and you guys try to find clues to the old man. Remember, time is running out."

"Are you really sure you want to find this detective?" Lin Feng looked at the business card handed over by Wang Hao, which had the words "Detective Sherlock Wang Ergou" printed on it in large letters, and couldn't help but twitching his lips.

"Don't be fooled by his unfashionable name. This guy studied abroad and is very professional!" Wang Hao patted his chest and assured, "I paid a lot of money to hire him."

The next morning, a young man in a plaid suit and a peaked cap swaggered into the hospital. He held a magnifying glass and would occasionally squat to observe the ground, attracting the attention of passing patients and their families.

"Are you Lin Feng?" Wang Ergou pushed up his sunglasses and said in a serious tone, "Judging from your face, you've definitely been in some serious trouble recently."

Lin Feng looked at him speechlessly: "You knew this from Wang Hao, right?"

"That's a detective's intuition!" Wang Ergou waved a magnifying glass. "Now take me to the crime scene. I want to look for clues."

Arriving at the ward where the poisoning occurred, Wang Ergou began his "professional investigation." He was seen crawling around on the floor with a magnifying glass, sometimes frowning in thought, sometimes suddenly realizing something.

"I've found something!" Wang Ergou suddenly jumped up and pointed at a cigarette butt on the ground. "This is an important clue!"

"That's the cigarette smoked by the cleaner." The nurse reminded in a low voice.

Wang Ergou coughed awkwardly: "Of course I know, I'm just eliminating irrelevant clues."

Over the next few days, Wang Ergou's investigation was filled with hilarious twists and turns. He secretly followed a food delivery driver, finding him acting suspiciously; he searched through trash cans for hours, only to find a few empty lunch boxes; and he even questioned the hospital's lucky cat, believing its eyes were filled with murderous intent.

The most ridiculous thing is that Wang Ergou actually bought a set of high-tech equipment, claiming to conduct "scientific evidence collection". As a result, when the equipment arrived, he trapped himself inside, and finally it was Lin Feng who helped to rescue him.

"Wang Hao, is your friend really a detective?" Lin Feng asked privately.

Wang Hao scratched his head. "Actually, his family runs a mine, and being a detective is just a hobby. He's read so many mystery novels that he thinks he's the reincarnation of Sherlock Holmes."

"Has he ever solved a case?"

"Yes, he helped me find my lost pet dog last time." Wang Hao said seriously, "But later I found out that the dog was not lost at all, and was sleeping in my backyard."

Lin Feng was completely speechless.
