In fact, Shi Fei had been on tenterhooks these past few days, afraid that he would be caught by the police.

Shi Fei's worry came from the report that the police had sent to the school stating that someone had added a senna leaf to the spring water used by the Grand Auntie's Dining Hall.

Although the report indicated that the police had already closed the case, Shi Fei was extremely terrified, because from the school medicinal material bank, he stole a few senna leaf and passed them to the president of the student council, Li Xuewen.

As for what Li Xuewen did with the senna leaf, Shi Fei did not know, but that did not stop him from connecting the dots.

Because Li Xuewen had been interacting with the students of the Chinese medicine department in the Student Union for a period of time, Li Xuewen did not know the reason why he was in contact with the other students.

However, Shi Fei was very clear on the situation where Li Xuewen had come into contact with him. He had first consulted Shi Fei about the effects of the Chinese medicinal herbs, whether or not there would be any medicinal herbs with symptoms similar to food poisoning among the Chinese medicinal herbs.

Shi Fei's grades were very good, so naturally he knew that senna leaf could achieve such an effect. Thus, he told Li Xuewen what happened next, and Li Xuewen went into the medicinal material bank, stole the senna leaf s from the school's medicinal material bank, and gave them to Li Xuewen.

After that, there was the matter of the students being poisoned.

Shi Fei originally thought that it was really food poisoning, but from the police report, after they sent it to the school, Shi Fei knew that it was most likely Li Xuewen who did it.

Shi Fei had also secretly asked Li Xuewen a few times whether the incident of the senna leaf being poisoned at school was related to Li Xuewen.

Li Xuewen's answer was always simple. Even the police had already finished their cases, so of course it wasn't done by him! As to what the senna leaf was used for, Li Xuewen did not answer.

The interrogation of Shi Fei soon ended, Brother Wang allowed Shi Fei to look at the written report. After confirming that there was nothing wrong, he got Shi Fei to sign his name and press his hand seal. Afterwards, the Brother Wang took Shi Fei and left the interrogation room.

Lin Rong came out of the interrogation room and showed the interrogation records to Chen Hui. The only reason why this case had progressed to this stage was because of Chen Hui, so it was normal for him to see the records.

Moreover, this case involved a student, and he was also the president of the student council.

After Chen Hui read the statement, he returned it to Lin Rong, and said: "It matches the information I found earlier, there's nothing to be surprised about. The reason why Li Xuewen walked so close to the students of the Chinese medicine department is so that they know what kind of medicine he ate, and he would have the same symptoms as the food poisoning. Furthermore, he even kept a lookout for Shi Fei, and allowed Shi Fei to steal the senna leaf in the school's medicinal material bank.

"The next step, is to capture Li Xuewen." Lin Rong nodded her head, showing that she agreed with what Chen Hui had said, this case had indeed been brought to light.

"Do you still want to bring Li Xuewen out of school for arrest?" Chen Hui could not help but ask at this time.

Lin Rong waved her hand, and said: "No need, other than Li Xuewen, there's only Yan Zhen left. I'll send you back to school, and also bring some people to catch Li Xuewen, and at the same time I will arrange for some people to keep an eye on him, so we won't be able to run away."

Chen Hui nodded and heaved a sigh of relief. He said: "I don't think I need to help with the rest of the matters? "Now that the case has progressed to this point, the rest of it should be handled by you cops, right?"

Lin Rong immediately nodded his head, and said: "The remaining thing to do is to obtain Li Xuewen's confession, and then we will be able to arrest Yan Zhen. Although this case is not over, but, we do not need you to do anything for us, thank you!"

"You only need to thank me?" Chen Hui went over to Lin Rong's side and asked with his eyebrows dropped.

Lin Rong stared at Chen Hui and asked puzzledly: "Otherwise, what do you want to do? Give you a good citizen award? "

"No!" Chen Hui lowered his voice, and smiled mischievously at Lin Rong, and said: "Have you forgotten our agreement?"

Hearing Chen Hui's reminder, Lin Rong suddenly remembered that when she had agreed to Chen Hui's promise before, she had been extremely mighty and domineering.

"I said that I would only give you such a reward if I solved the case!" Lin Rong coughed a little, trying to ease her awkwardness.

"Right, isn't the case solved now?" Chen Hui said earnestly: "Actually, the next step is no different from closing the case, and the most important thing is that I am no longer needed. To me, this case can be considered closed! Are you trying to break the promise? "

"I'm not that kind of person!" Lin Rong was agitated by Chen Hui, and her voice suddenly increased by another eight degrees.

Seeing the mischievous smile on Chen Hui's face, Lin Rong immediately understood that she had been tricked by Chen Hui!

It was obvious that Chen Hui had a bad temper, he could not bear to be provoked!

"Then give me the reward!" Chen Hui said as he pouted and walked towards Lin Rong.

Lin Rong felt his heart beating extremely quickly. This was her own Criminal Police squad, how could she give Chen Hui a reward here?

However, this feeling of his heart beating faster made him feel inexplicably happy!

At the same time, it also made Lin Rong want to secretly kiss Chen Hui. Once this idea popped out in her mind, she couldn't suppress it anymore, because just thinking about it made him feel extremely excited.

Somehow, Lin Rong actually went closer and kissed Chen Hui on the lips.

However, Lin Rong did not expect that Chen Hui would do something like this. A hand secretly reached behind his waist and pulled him into her embrace.

Lin Rong gasped in surprise, but the voice was immediately covered, because Chen Hui had already kissed Lin Rong heavily. Furthermore, Chen Hui had already experienced this kind of wonderful sensation, and began to invade Lin Rong's body as if he was familiar with the route!

"Ugh …" Lin Rong had never experienced such a scene before. She could only make one unclear sound and she was completely stunned.

Instinctively, Lin Rong replied. At the door of the interrogation room, Chen Hui hugged Lin Rong, and both of their heads shook left and right …

One of them held onto the folder in his hands. As he stared at the folder in shock, he forgot that he was still holding onto something and pointed to Chen Hui and Lin Rong. As for the folder in his hand, it dropped onto the ground, letting out a "Pa" sound.
