Mayor Zhang Hongwei stayed in the hospital until all the students had no symptoms, then he could be considered to be completely relieved.

As the afternoon neared the end of work, the hospital's laboratory results came out. This time, the poison in the students' food poisoning was the composition of the senna leaf.

Dean Wang handed the test results over to Zhang Hongwei. Although Zhang Hongwei understood the words "senna leaf poisoning", he did not know what the senna leaf was and could not help but ask: "What is a senna leaf?"

Chen Hui had already fed the medicinal soup to the dozen students. Hearing Zhang Hongwei's question, Chen Hui said: "Mayor Zhang, can I talk to you alone?"

"Sure!" Zhang Hongwei immediately said, and at the same time walked to the side.

Chen Hui followed along and said softly: "senna leaf s are only Chinese medicinal herbs, the fierce medicine of the laxative!"

Hearing Chen Hui's words, Zhang Hongwei suddenly frowned. After a moment of thought, Zhang Hongwei came to a realization and said in a low voice, "You knew about it since a long time ago?"

"Yes, the reason why I didn't tell you the truth is because I have already told Captain Lin Rong the truth." Chen Hui explained: "It's impossible for the school cafeteria to add senna leaf into the dishes, so this time, someone should have poisoned the food, and in order to help Captain Lin Rong with the case, I did not tell him the truth previously. Now that I have come out to test the results, I can't hide it anymore."

"So Captain Lin is handling this case." Zhang Hongwei nodded his head, and said: "I understand, you have done this very well, if the truth were to be known by many people, it would be hard to avoid people talking too much, and there would be no need for secrecy. It's good that I got the news relatively early, and sealed off the hospital and the school, otherwise, provoking the reporters would be a very troublesome matter."

Just then, Chen Hui's computer rang. Chen Hui saw that it was an unfamiliar number and connected to the phone. He asked: "Hello, I'm Chen Hui, who is this?"

"Lin Rong!" Lin Rong's voice came from the other side of the phone, there was a sense of annoyance mixed within the fatigue, and she asked: "Is the hospital finished? "After you're done, come out and have a drink with me tonight!"

"What's wrong? Is the case progressing poorly? " Chen Hui immediately recognized the problem.

"I can't explain it clearly in a few sentences. Are you done yet? I'll pick you up from the hospital when I'm done. " Lin Rong said impatiently.

"I'm done. Come over." After Chen Hui said this, the phone call was cut short by Lin Rong.

Zhang Hongwei asked at this time, "What's wrong? Is things not going well on the Captain Lin side? "

"It should be, but she didn't say anything. She only invited me to dinner and asked me to accompany her for a few drinks." Chen Hui laughed bitterly and said.

Zhang Hongwei nodded his head, and said: "Let's do it like this, we'll leave the case to Captain Lin, there won't be any problems, the poisoned students are already fine, I should also be going now."

After Zhang Hongwei said this, he returned to Dean Wang's side and warned him to keep the news that his students had been poisoned by senna leaf tightly. To the outside world, it could only be said that their students had been poisoned by food.

Zhang Hongwei brought his secretary Lu Quan and left the hospital, but after getting out of the car, Zhang Hongwei did not start the car, but said to the driver: "Captain Lin from Criminal Police Team One will come over later to pick his up, keep up with her car."

These poisoned students had already been cured, and the mayor had also ordered for the senna leaf to be sealed off, so the matter at the hospital was considered to have come to an end.

Jiang Xian brought Jiang Jingxiu to Chen Hui's side and said with a smile: "Are you coming to my house to eat tonight?"

"Elder Jiang, I really can't do it tonight. I've already made an appointment." Chen Hui said with a smile.

"It's fine, I'm waiting for you to have the time." After Jiang Xian finished, he led Jiang Jingxiu away.

Chen Hui also walked out of the hospital building and stood at the entrance waiting for Lin Rong.

Not long later, Lin Rong drove his car to the entrance of the hospital, and without wasting time, he got in the car.

Lin Rong turned the car around and drove forward. She stopped at a place near the outskirts of the city, her destination being a barbeque shop.

Lin Rong got off the car and directly sat down at a table, then asked the shop owner for a barbecue beer, as he was familiar with the place. The barbeque store's stall was on the side of the road, and the barbeque store's stall was on the side of the road.

From the looks of it, Lin Rong seemed to come here frequently and was a frequent customer of this barbeque shop.

Along the way, Lin Rong did not speak much either, because he could tell that Lin Rong was in a rather bad mood.

Not long after, the stove on the table was filled with charcoal, and the kebabs were sent to the table along with cold beer.

Without saying a word, Lin Rong opened a bottle of beer and directly blew at the beer bottle. Chen Hui was dumbstruck.

"Slow down, slow down!" Chen Hui saw that Lin Rong had finished half a bottle of beer in one breath, and immediately reached out to grab hold of Lin Rong, saying: "Even if the case does not go well, it shouldn't have ended up like this!"

Chen Hui and Lin Rong did not realise that there was a car parked across the road, and that the people inside the car were smiling at her actions.

"Looks like, our Captain Lin's case didn't go well this time!" The one in the carriage was none other than Zhang Hongwei: "You're using this to pour water on us, aren't you?"

Lu Quan laughed and said: "Captain Lin's fiery temper is famous in the police force, and handling cases is swift and decisive. With her temper, handling cases is rarely convenient!"

"You guys wait here, I'll go over to Captain Lin and barbeque some food." Zhang Hongwei said as he pushed the door open and got off the car, then went straight to Chen Hui and Lin Rong's table.

By the time Zhang Hongwei walked to the front of the table and stood still, Lin Rong had already finished two bottles of beer, yet she had not eaten a single skewer.

"Captain Lin, you are borrowing wine to pour out your worries!" Zhang Hongwei said with a smile.

"Mayor Zhang!" Lin Rong and Chen Hui stood up and said at almost the same time.

"Captain Lin, do you have any objections to barbeque?" Zhang Hongwei said with a smile.

How could Lin Rong have any objections? She quickly invited Zhang Hongwei to sit.

Zhang Hongwei picked up the beer from the table, and poured a cup for Lin Rong and Chen Hui respectively. He also poured a cup for himself, and said: "How can we just drink and not eat? No matter how difficult the case is, there's always a way to handle it.

"Here, a toast to both of you." Zhang Hongwei raised his wine cup and drank the beer inside, then said: "At this time, drinking a cup of ice beer is really cool!"

Chen Hui and Lin Rong finished their beer and put down their wine, but still did not say a word.

Chen Hui didn't know what to say, and although the two of them didn't speak, there were different reasons why Lin Rong didn't want to.

"Why aren't you talking? Did I disturb your two young people from eating? " Zhang Hongwei asked with a smile.

Lin Rong quickly replied, "How is that possible!?"

"Then let's talk about the case." Zhang Hongwei laughed and said: "How far have you progressed?"
