The doctor took off his mask and came out.

Guan Feng quickly stepped forward, showed his identification, and asked, "Doctor, thank you for your hard work! How is the patient?"

When the doctor saw Guan Feng's identification, his expression softened slightly. He nodded and said, "Thank goodness! He's been saved. However, the patient is very weak. The food poisoning caused extensive dehydration, and there are other complications. He needs to rest quietly. You can't ask him any questions for now."

Guan Feng breathed a sigh of relief and said, "Don't worry, doctor, we won't ask any questions, we just want to know the results."

The doctor said, "There is no immediate danger to his life."

Guan Feng said, "That's good! Thank you for your hard work, doctor."

The doctor shook his head and said, "What's so hard about it? Saving people is the greatest comfort. You guys need to find out what happened quickly. We've admitted thirty or forty patients this morning, all with vomiting and diarrhea. If this continues, our hospital won't be able to handle it!"

Guan Feng explained, "This is most likely a mass poisoning incident. We have identified the source and are investigating. As for the issue of strained medical resources, we have reported it to our superiors, and more medical resources should be transferred here in the future."

The doctor said, "That's good! That's good!"

Seeing that the doctor looked tired, Guan Feng said, "Doctor, you should get some rest. We'll go back first." He and Zhao Dong returned to the outpatient department.

Guan Feng looked at Liu Shengguo and instructed him: "The critically ill patient has been rescued, and the worst situation has not occurred. Next, you take Qi Xia to visit the patients with mild symptoms here, find out what they ate, and rule out all possibilities. Zhao Yang and I will go to the hotel."

Liu Shengguo said, "Captain, you go over there. Qi Xia and I will handle things here."

Guan Feng nodded, then looked at Zhao Yang and Huang Lili and said, "You two come with me. Director Zhao, what about you? Do you need to go over there?"

Director Zhao said, "Director Chen just asked me to go over. This case has attracted the attention of the leadership. Vice Mayor Zhang asked Director Chen to go over and inquire about the situation. I will go along with him."

Guan Feng said, "Then Director Zhao, you're busy. We'll keep in touch if there's any news."

Zhao Dong nodded and said, "Hurry up and investigate the case, especially the test results, which need to be available as soon as possible."

Guan Feng said, "We are working on two fronts simultaneously, with the hospital and the technical department conducting investigations at the same time. We will definitely find out the extent of the toxins as soon as possible."

Zhao Dong said, "Then let's set off."

The two cars sped off in different directions.

......

Huilong Street Police Station.

Guan Feng saw several people sitting in the office, looking disheveled.

Guan Feng looked at the group and asked Director Zhao, "Are they the people in charge of the hotel?"

Director Zhao nodded and said, "Yes! The slightly chubby man in the middle is Chen Donglai, the person in charge of the banquet hall. The one on the left is the head chef of the hotel, and the one on the right is the manager in charge of daily operations."

Guan Feng nodded and asked, "Did you get anything out of them?"

Director Zhao shook his head and said, "No! All three of them are tight-lipped, and we don't know which dish caused the problem. I just questioned them separately, and the results were consistent. They must really be unaware!"

Guan Feng said, "Arrange a room for me; I need to question you."

Director Zhao said, "Okay! It can be in my office."

Guan Feng nodded, then called out the head chef's name and said, "Call that chef over first."

Director Zhao said, "Okay, I'll bring him over."

......

Director Zhao's office.

Guan Feng looked at the chef in front of him and asked, "What are your thoughts on this incident?"

The head chef looked completely bewildered and said, "I really don't know anything! I've been cooking normally for years. If I wanted to poison someone, would I have waited until today? No! I mean, it really wasn't me! I only make this much money a month, it's not worth going to jail!"

Guan Feng said, "Your reasons are very valid, but now that it has been confirmed, how do you explain it?"

The head chef asked in surprise, "Is it really food poisoning? Didn't I hear it could be due to spoiled food?"

Guan Feng said, "It's definitely food poisoning!"

The chef's face changed immediately, and he shook his head, saying, "How is this possible? What kind of people are these? How could anyone do such a thing? Do they want to die?"

Guan Feng observed the other person's expression, which didn't seem feigned, and asked, "Who's in charge of the hotel's procurement?"

The head chef said, "Manager Du will find someone to make the purchases."

Guan Feng asked, "Is there no one in your kitchen helping to supervise the process?"

The head chef shook his head and said, "How could that be! Purchasing is where the real money is made. How could we be qualified? The manager is the boss's brother-in-law. Only he is qualified to purchase these ingredients."

Guan Feng asked, "What are the specific procedures?"

The head chef explained, "Meat that can be kept for two days is usually bought in advance and stored in the refrigerator. Vegetables and eggs are bought early in the morning in a van and then transported to the kitchen, where we cook as usual."

Guan Feng asked, "How many people usually go grocery shopping with you?"

The head chef said, "Two people, assigned by the manager, one to drive and one to purchase, will work together to move the goods."

Guan Feng continued, "Describe the situation at that time?"

The head chef said, "Yesterday was the banquet! More than 20 tables. We prepared the dishes in advance, plus the freshly cooked dishes. Everything was the same as before. But I didn't expect to hear this morning that there was a problem with the dishes. I hadn't even gone to the restaurant yet, and you brought me here."

Guan Feng asked, "Was there a problem with the vegetables at lunch yesterday?"

The head chef said, "No problem! We had quite a few tables at lunchtime too, but I haven't heard anyone complain. Could it be just at night? That doesn't make sense. The ingredients are the same for both lunch and dinner, so why did only the people at night get food poisoning?"

As the head chef spoke, an expression of disbelief appeared on his face.

Guan Feng astutely grasped the key information and asked, "What dishes were not made for lunch but were made for dinner?"

The head chef thought for a moment, then shook his head and said, "No, it's a banquet! The dishes are all the same, eight meat dishes, eight vegetable dishes, and some other things. It's a fixed combination. There's no dish that wasn't served at lunch but was served in the evening."

Guan Feng cautioned, "If you weren't poisoned at noon but were poisoned at night, it means there must have been a difference in the ingredients. If you're unsure, ask the chefs below if there were any dishes that were different."

The head chef said, "Then I'll make a phone call and ask."
