Lin Yu was immediately excited when he received this call, after waiting for so long, he finally had a clue!

Without the slightest delay, he said hello to Jiang Yan and the others, and then drove to the Li Bioengineering Project with Ye Qingmei.

Although it was close to midnight at this time, the headlights were on at the gate of the Lee's Bioengineering Project, and several trucks were driving in at the door, while a mirrored building inside was still brightly lit.

Lin Yu and Ye Qingmei were a little puzzled when they saw these trucks, and glanced at each other, obviously not knowing what was going on, Lin Yu walked directly to a truck that was queuing up to unload, and asked the driver sitting inside, "Brother, what are you transporting here?"

"Honey!"

The driver said to Lin Yu with some accents.

"Honey?!"

Lin Yu was suddenly a little puzzled when he heard this, then looked at Ye Qingmei, and said suspiciously, "Is there not enough honey in our medicinal herb store?"

"No......"

Ye Qingmei also shook his head with some doubts, and said with a frown, "We use a very small amount of honey on weekdays, and recently affected by the oral liquid incident, the company has not produced any products on a large scale, so we shouldn't use honey!"

"Let's go, let's go up!"

Lin Yu didn't bother much, and walked directly to the upstairs office with Ye Qingmei, and when he saw Li Qianjue, everything was understood.

At this time, four or five executives in black uniforms were gathered at their desks in Li Qianjue's office, listening to what Li Qianjue said.

"Jiarong, hurry up!"

Li Qianjue's face was overjoyed when she saw Lin Yu, and she hurriedly waved at Lin Yu and motioned for Lin Yu to step forward.

"He is always good!"

After seeing Lin Yu, several executives greeted Lin Yu with great respect and automatically gave Lin Yu a position.

"Hello, I'm working overtime so late, it's hard!"

Lin Yu greeted everyone with a smile, and then walked to the desk, and found that there were piles of A4 paper documents on the desk, and many marks were drawn with a pen.

Li Qianjue picked out a few of the A4 papers and handed them to Lin Yu, and said happily, "Jiarong, I asked people to check carefully according to what you said, and sure enough, I found a clue!"

"Oh?!"

Lin Yu hurriedly took the paper and browsed it carefully.

Ye Qingmei also immediately came to him, glanced at the A4 paper in Lin Yu's hand, and saw that the paper was densely written with green onions, beef, cumin, red wine and other things, and was immediately confused, and asked Li Qianju suspiciously, "Mr. Li, what did Jiarong ask you to check......

"Check the diet of these patients!"

With a hint of excitement in her eyes, Li Qianjue said excitedly, "And it's going to be investigated in great detail! In order to check carefully, I specially spent millions of dollars, hired several teams, and turned the axis for so many days and nights, until today, I finally found my eyebrows!"

"Check the patient's diet?!"

Ye Qingmei was even more puzzled when he heard this.

"Yes, check what these patients' diets have in common, that is, what other things did they eat at the same time in addition to taking Changsheng Oral Liquid!"

Li Qianjue said with a smile.

"Huh?"

Ye Qingmei was a little surprised when he heard this, and said in surprise, "There are so many people, and they come from all over the country, and their eating habits are different, how can they eat one thing for a long time at the same time?!"

"Yes, people all over the country have different eating habits!"

Lin Yu said with a smile while flipping through the paper in his hand at this time, "But they all have to eat vegetables, they all have meat, they all have to drink water, drink wine, put salt and sugar and use seasonings, these are all common points!"

In fact, Lin Yu's thinking at the beginning was the same as Ye Qingmei's, thinking that so many patients came from all over the country, how could they consume the same thing for a period of time!

And Li Qianjue also had this kind of psychology when he investigated before, so he just checked it and saw that the eating habits of these patients were varied, thinking that it had nothing to do with food, so he didn't continue to investigate in depth.

It wasn't until that day that Lin Yu's father-in-law talked about drinking medicinal wine and reacting to the Chinese medicine he was taking, that Lin Yu suddenly realized that things like wine, especially some brands with large advertising investment and high visibility, could be drunk on a large scale by people all over the country!

So Lin Yu called again and asked Li Qianjue to check carefully, and he made today's discovery.

Ye Qingmei also suddenly realized after hearing Lin Yu's words, but she couldn't help but be a little suspicious in her heart, things like spices, vegetables and meat, did not conflict with their oral liquid, and even the wine did not have any conflict with their oral liquid!

As a person who has specialized in traditional Chinese medicine, she has a clear reaction to the relationship between medicinal materials and food, so she feels that even if she finds something, it may not necessarily be of any help, but seeing Li Qianjue's excited look, she doesn't have to say anything, and with such a great god as Lin Yu, there is no need for her to get an axe.

"How is it, Jiarong, have you found out?!"

Li Qianjue said with a smile, "Anyway, it's in these few pieces of paper, you can find it slowly!"

"No, I've already guessed it!"

Lin Yu was a little dazzled when he looked at the small words on the paper, so he simply closed the paper directly, and smiled at Li Qianjue, "As expected, it should be honey!"

Li Qianjue was slightly stunned, then laughed and said, "When you went upstairs, you ran into the truck below?!"

"Mr. Li, you mean that all patients across the country have taken honey during the medication?!"

Ye Qingmei was suddenly a little surprised, then glanced at Lin Yu, and hesitated, "But...... Our liquid doesn't react with honey in any way......"

"Yes, our medicine really doesn't have any taboos!"

Lin Yu nodded with a smile and continued, "But who knows what's added to these honeys?!"

Ye Qingmei was slightly stunned, and then suddenly realized.

"Hehe, Jia Rong told me a long time ago that once they find out that they have eaten something the same, they will immediately test it!"

Li Qianjue looked at Lin Yu's eyes with some admiration, and said with a smile, "So I have already instructed the people from the inspection department to test the honey, but it will take some time, wait patiently!"

Lin Yu nodded with a smile, and said a little helplessly: "Brother Li, I said to let you test, but I didn't say that I want you to move the honey from the entire production plant back for testing!"

Lin Yu judged by the number of trucks below and the tonnage of the trucks just now, that the honey transported in this time might be dozens of tons.

"It's all evidence!"

Li Qianjue hurriedly said.

"You don't need so much evidence!"

Lin Yu shook his head and smiled.

"Hey, just listen to me tell you!"

Li Qianjue smiled, then took the paper in Lin Yu's hand, then picked up a pen, pointed to a few circles on the paper and said, "See, south of Lingnan and Huaijiang River, in this area, the honey brand that these patients drink is called Yuanxiang, and in the area of Ling'an and Qinghai, the brand of honey drunk by patients is called Pinxuantang, and further north, Lubei and other places and the capital, the brand of honey drunk is called Natural Wind!"

Lin Yu frowned, obviously a little surprised, and said suspiciously: "The brands they drink are different?!"

"Yes, the brand is different! And I have investigated, although there is no connection between these three, and there is no connection between legal persons!"

"That's not right......"

Lin Yu sighed softly, his expression a little lost.

If the brand of the patient drinks is different, and there is no connection between these brands, then the probability of someone tampering with the honey will be greatly reduced.

Li Qianjue smiled at Lin Yu and said, "This kind of trick can deceive others, but it can't deceive me, I specially sent someone to investigate, although the legal person of these three honey companies has not changed, but three months ago, their company was suddenly acquired by a mysterious person at a high price, and this mysterious person still let them serve as legal persons, that is to say, this mysterious person just used this money to buy a management right!" Immediately afterwards, these three companies dumped honey with very large discounts, and the purchase volume surged instantly, especially the old men and old ladies who love to be cheap, and many of these consumers are consumers of our Li Changsheng oral liquid!"
