Soon the three of them returned to the campus of Shandong University, Ye Xiaoxuan asked Lao Zhuang to wait in the parking lot, and took Guan Ling and Yuan Caiyi straight to the laboratory, and Ah Cai was waiting for them at the door.

Seeing everyone coming, Ah Cai made a silent gesture to everyone, asked everyone to change into disposable slippers, put on hats and gloves, walked into the laboratory, pointed to an old man whose glasses were thicker than the bottom of a beer bottle, and said, "This is Professor Sun!"

Ye Xiaoxuan and Guan Ling hurriedly bowed and said hello, Professor Sun pushed the glasses on his nose, looked at Guan Ling and said, "How did you get these things?"

Ye Xiaoxuan knew that this kind of academic person generally didn't like nonsense, and he said all the questions straight to the point, so he hurriedly answered him: "Just pick it up by the river!"

Professor Sun looked at him from behind his glasses and said, "You really know how to pick it up! I can't pick it up if I want to!"

When Ye Xiaoxuan heard this, why did he still pick up the treasure? Last night, the kid in Qi Yunlou didn't sleep in the middle of the night and came out to throw gold sand?

Guan Ling said anxiously, "Professor, what are those things?

It seems that this old man is not old-fashioned, at least he is very polite to the uniformed speaker, he pushed his glasses and said: "For you, it is worthless, but for us who are engaged in chemistry, it is very precious! There are several ingredients in it that I have never thought of, and I can't imagine that someone has almost succeeded in doing it!"

The more Ye Xiaoxuan listened, the more confused he became, and asked Professor Sun, "What are those things for?"

Professor Sun said: "It's all a mixture of mung bean flour, snail meat, eggplant sauce, tomato juice and so on!"

When Ye Xiaoxuan heard this, he was immediately deflated, and said depressedly: "After working all night, I picked up other people's supper as a baby!"

Guan Ling was also a little frustrated, pouting and saying, "I came all the way here just for a bag of garbage!"

Yuan Caiyi took the arms of the two of them and said, "Don't be discouraged first, the professor hasn't finished yet!"

Professor Sun glanced at Yuan Caiyi approvingly and said, "It's still Xiaoyi who is calm! These things look like garbage to you, but in my eyes, they really kill people with invisible poison!"

"Poison?" Ye Xiaoxuan and Guan Ling exclaimed at the same time, raising their heads and staring at Professor Sun with an expression of disbelief!

Professor Sun nodded and said, "Many things are mutually restrictive, such as mung beans and tomatoes, and if you take them too many times at the same time, it will hurt your vitality! If you mix it with a little more special thing, it will be even more powerful, and it seems inconspicuous on the surface, making people completely defenseless!"

Ye Xiaoxuan and Guan Ling both saw a surprise in each other's eyes, and Qi Yunlou's tail was finally revealed!

Guan Ling said eagerly to Professor Sun: "Professor, what kind of poison is this? Is it very toxic, is it widespread? Can you give me the test report and take it away?"

Professor Sun said expressionlessly: "Don't worry, the people who make these things are still in the final experiment, and the toxicity of these mixed materials is not the most ideal state!

Ah Cai looked at the professor with admiration and said, "Tutor, you are so good, you can see this!"

It seems that Professor Sun has a straight face and reprimands her seriously: "Ah Cai, I have told you many times, we must pay attention to academic rigor!

You see that these ingredients are all reusable, and according to the method of arrangement I just now, the restraint is gradually increasing, but it is still thrown away and discarded, which can prove that this person is the character I described, which is a very simple truth!"

Ah Cai stuck out her little tongue, lowered her head and answered honestly: "Mentor, I know!" and quietly turned his head and grimaced at Yuan Caiyi and the others.

Professor Sun looked at a few mud-like things on the tray, his eyes shot with excitement, and his expression made people see that he seemed to treat these piles of things that were more disgusting than poop as treasures, and he couldn't wait to plunge into them and eat them!

"This man is simply a medical genius! Maverick method, bold innovation, if there is fate, I want to have a good chat with him, I can worship him as a teacher, I am afraid that he will think I am dull, and refuse to accept me!"

Ye Xiaoxuan sweated and said to Professor Sun: "Save it! This person doesn't learn and has no skills, he is full of harm to others, and he doesn't do the right thing! Besides, how old are you, and you still worship others as teachers?"

Professor Sun glared at him and scolded him: "What do you know? Knowledge does not distinguish between good and evil, toxicology is the same as pharmacology, and the master of using poison is also an expert in saving people! Besides, there is no end to learning, I am only sixty-eight this year, and I am young!"

This old man has a good mentality, and he feels young at sixty-eight, but he can't walk, and he has to be supported by people on the wooden steps of the laboratory...

Guan Ling looked at Professor Shu and asked him, "Professor Sun, according to your experience, is there anyone in your impression who would make this poison?"

When Professor Sun heard this, he really frowned and thought for a while, and suddenly seemed to think of something, and his face became very ugly, neither pale nor red, but a little yellowish, just like jaundice!

"No! I've never been out of the lab in my life, and I don't know anyone at all!" Professor Sun said impatiently, and said to Ah Cai: "Ah Cai, you let them out, I'm tired too." The inspection report can be taken away, and these things can be put here!"

Ye Xiaoxuan, Guan Ling and Yuan Caiyi looked at each other, not understanding that this old man suddenly became so cold and wanted to drive people away?

I wanted to ask a few more questions, but Ah Cai hurriedly waved his hand at them and made a retreat gesture, and the three of them had no choice but to walk out of the laboratory with the test report.

Ye Xiaoxuan and Guan Ling walked to the side of the car with the inspection report, and said to Yuan Caiyi and Ah Cai: "Thank you, we have to go back quickly, otherwise it will be dark!"

Yuan Caiyi was a little reluctant to sort out his clothes for him, patted his collar and said: "The end of the month is the Mid-Autumn Festival, and the competition is over at that time, come and pick me up!"

In public, Ye Xiaoxuan didn't want to be too affectionate, it felt like showing affection to others, which was very hypocritical. Just squeezed her little hand and said, "Okay!"

The car drove out of the school, Guan Ling slapped the test report in his hand, and said to Lao Zhuang excitedly: "Brother Zhuang, let's go to the city bureau, let the above transfer a few people, and arrest the people in Qi Yun Building!"

Ye Xiaoxuan gently knocked her on the head next to her and said, "Don't be so naïve, okay? Let's not talk about whether the city bureau dares to touch these people, just with this test report, what can it prove? It can only prove that these things can't be eaten!"

Guan Ling said angrily: "But these things were thrown out of Qi Yunlou!"

Ye Xiaoxuan glared at her and said, "What about the evidence? You are still a policeman, why can you arrest people without evidence? If you can't characterize them, you can only treat them as suspects, not criminals, in that case, not only will it be useless, but it will also startle the snake!"

Guan Ling anxiously paced his little feet and said, "Do you just let them do evil? If this thing is really successful, it will kill many people, and no one can predict whether there is poison in the rice bowl they are carrying!"

Ye Xiaoxuan waved his hand in contemplation, and muttered in his mouth: "Let me think about it, think of a way to deal with this person!"

Guan Ling said angrily: "I think that Professor Sun must know who the person who designed these poisons is, but I don't know why he just didn't say it!

Ye Xiaoxuan shook his head: "Perhaps, he doesn't want to think about it, or maybe he has committed some kind of illness! This kind of person who engages in scientific research has always had a strange temper and doesn't like to deal with people!"

It was getting dark, and the car returned to Zhuangyuan Township. Guan Ling pulled Ye Xiaoxuan to deliberately turn around in front of Qi Yunlou, and said angrily: "I don't know why, I don't have a good impression of everyone here, and I can't wait to arrest them all!"

Ye Xiaoxuan nodded and said, "Well, that's right, you just need to have a good impression of me as a man, nothing else matters!"

Guan Ling angrily twisted him and said, "You hate it! People are talking to you about business, and you are still here to watch jokes!"

Ye Xiaoxuan laughed, hugged her shoulders and said, "I'm not kidding, the people here are really annoying, sooner or later one day I will blast them all out!"

Guan Ling hurriedly covered his mouth and whispered, "Why are you shouting so loudly!"

Ye Xiaoxuan shook off her hand and said, "What, are you afraid of them? I'm not afraid! If you have the ability, you will come and beat me, I don't believe they have the guts!"

Guan Ling is very strange, what is this kid stimulated? It's not like his usual appearance at all! It's not his style!

When he was far away from Qi Yunlou, Guan Ling looked at Ye Xiaoxuan cautiously and asked him, "You guy is a little weird tonight!"

The corners of Ye Xiaoxuan's mouth curled, smiled evilly, and asked her with a grassroots in his mouth: "Is there one? Why don't I feel it?"

Guan Ling grabbed his arm and said, "I don't care, you can't learn from that old man Sun! What do you have to tell me, what the hell are you doing?"

Ye Xiaoxuan knew that this girl had a quick temper, and if she didn't figure it out, she really wouldn't even be able to sleep well, so she smiled and said, "Since we can't get in, let's just let them out!"

Guan Ling frowned and pondered, then immediately looked at him with a smile and said, "Oh! I see! You want to lure the snake out of the hole! But what if they don't come out?"

Ye Xiaoxuan smiled slightly, and said to her: "There is always something to come out! They are no less interested in me than we are to him, otherwise they would not let the Mandarin Duck Swordsman bring us a message! Calm down, the show has just begun!"

Guan Ling hugged Ye Xiaoxuan's arm with admiration and said happily: "Little gangster, I found that being with you seems to make everything easier, no matter how tricky the case is, it will become very interesting!"

Ye Xiaoxuan smiled, pinched her little face and said, "You have a lot of advantages as a man! Let's go, now go back to the village, and the people at home are also in a hurry!"

Guan Du has already repaired the tires. Ye Xiaoxuan estimated that he had already seen what the relationship between his daughter and him was, but he didn't seem to care about it, so he was naturally not polite, swaggered upstairs with Guan Ling in his arms to get something, said hello to him and rode out!
