As the person in charge of the company, Cheng Yanling still has some understanding of the ingredients of the medicine, and the medicinal materials on the prescription do have a whitening effect, as for the extra Chinese medicinal materials, although she doesn't understand it, she still believes in Lin Feng's strength.

She carefully put away the prescription, raised her head and smiled: "Thank you so much, not only cured grandpa's illness, but also provided me with the prescription, I don't know how to thank you." ”

"Miss Cheng is too polite, but I do need your help with something, I have an urgent matter and need ten million, but in addition to the five million you gave last time, I am still five million short, so ......" Lin Feng rubbed his temples and said with some embarrassment.

After all, this amount of money is not a small amount, and Lin Feng is still a little apprehensive about asking for money.

Cheng Yanling smiled slightly, blinked her eyes, and said: "Just by curing my grandfather, I can take away 10 million, but I still need your help, I want to take this prescription to the research department for experiments, I'm afraid that something will go wrong, so I hope you can help me see it on the spot, no problem, right?"

Lin Fengwan said with a smile: "Of course there is no problem, of course I am willing to help with this first batch of products." ”

"Thank you so much, I'll transfer 10 million to the card I gave you before, and when I'm done researching this new product, I'll treat you to a meal." Cheng Yanling said with a smile.

"No problem, the beautiful woman has an appointment, how can I refuse? Okay, after this busy work, let's go to your place to study the product." Lin Feng teased, but his eyes were clear.

Seeing the other party's clear eyes, Cheng Yanling's impression of this smiling man was much better.

Lin Feng drove to the company's R&D department in Cheng Yanling's car, and as soon as he entered, he saw those busy R&D personnel.

When these R&D workers saw Cheng Yanling coming in, they stopped what they were doing and greeted them respectfully, and only after she left did they continue to be busy with their work.

At this time, a middle-aged man wearing glasses hurriedly walked over, smiling, and said in a kind tone: "Mr. Cheng, why do you have time to come over today." ”

"Okay, Uncle Zhang, don't be so polite to me, I brought a top talent over today, and he will help us make better products. After Cheng Yanling finished speaking, she looked at Lin Feng beside her and introduced to the other party, "Uncle Zhang, this is Lin Feng, who has studied Chinese medicine a lot, he found that there is a problem with our prescription, come and help us make up for the defects." ”

She tilted her head and introduced to Lin Feng: "This is Zhang Chao, the minister of our R&D department, with a doctorate degree, who is very good at skin care and cosmetics, and he has made great efforts to launch the company's new products." ”

Lin Feng smiled, stretched out his hand and said, "I'm Lin Feng, it's nice to meet you." ”

The other party pushed his glasses and didn't stretch out his hand, the man in front of him, not only dressed poorly, but also young, actually said that there was something wrong with his prescription.

"I don't know that you are a high-achieving student who graduated from college? Zhang Chao squinted his eyes and asked with some displeasure on his face.

Lin Feng withdrew his hand, smiled faintly, and said, "Graduated from junior college and do auto repair." ”

He is telling the truth, the previous master of the body is indeed this major, if it weren't for his grandfather, being an auto mechanic is Lin Feng's future path.

As soon as these words came out, not to mention that Cheng Yanling was a little surprised, Zhang Chao next to him sneered and said: "Mr. Cheng, Uncle Zhang doesn't have much time, don't joke with me, this is a prescription for people, not for cars." ”

Cheng Yanling frowned slightly, and said: "Uncle Zhang, Mr. Lin does have some skills, grandpa's illness was cured by him, I believe in his prescription, why don't we try it first?"

The news that Old Man Cheng was treated by a divine doctor spread throughout the company, and Zhang Chao naturally knew that no matter what, he couldn't imagine that it was Old Man Cheng who was treated by the young man in front of him.

He glanced at Lin Feng suspiciously, nodded slightly, and said, "It's okay to give it a try, but let's say it first, if this prescription can't be used, I hope that Mr. Cheng won't interfere in our prescription again." ”

Cheng Yanling was unhappy in her heart, this Zhang Chao usually relied on his old qualifications, arrogant attitude, and couldn't listen to other people's opinions, because of the research and development of prescriptions, he didn't quarrel with him less.

"Okay, if there is a problem with this prescription, I will never ask you about it again, but ......" Cheng Yanling smiled slightly and continued, "If this prescription is okay and works well, I hope Uncle Zhang will obey my orders in the future." ”

"A word is a deal!" Zhang Chao pushed his glasses and said with a smile.

He is very confident, even if this young man is indeed the doctor who saved the old man, but he has a specialization in the art industry, and he doesn't believe that the other party can do it.

The bet between the minister and the deputy general manager immediately attracted the attention of the people around them, who were busy with their work while looking towards where the two were located.

"Show me the prescription. Zhang Chao stretched out his hand and said.

Cheng Yanling took out the prescription from her arms and handed it over.

After a few hurried glances, Zhang Chao sneered in his heart, the foundation of this recipe is almost the same as the original, the only difference is that there are more ingredients of traditional Chinese medicine.

Returning the prescription to the other party, he glanced at Lin Feng contemptuously and said, "Take a look at it a little, it's just that, a few more ingredients of traditional Chinese medicine, that's all." ”

Lin Feng didn't speak, just smiled, Zhang Chao was even more sure in his heart, the young man in front of him was playing tricks on him, in order to attract the attention of Mr. Cheng.

Came to the laboratory table, ready to make the finished product, because the research room did not have the herbs on the prescription, so Cheng Yanling asked someone to go to the Chinese medicine hall to buy medicine, and during this waiting time, the researchers discussed the success rate of the prescription.

"I don't think so, how can I make a prescription at a young age?"

"That's it, I just heard him say that he repairs cars, how can he do it?

"I think it's the same, I look poor and sour, and no matter how I look at it, it's not a miracle doctor. ”

"I'm optimistic about him, didn't I say that it became the master's illness, or that he cured it?"

"But beauty is different, Minister Zhang has always been a leader in the research and development of beauty products, he said no, I don't think this young man has any fun. ”

There are different opinions, and most people are still not optimistic about Lin Feng, after all, this young man is too ordinary.

The medicinal materials were quickly bought, and Cheng Yanling immediately arranged for people to make them according to Lin Feng's prescription.

The pharmacist made the base, and Lin Feng brought the herbs, selected a certain proportion of the herbs to grind, and mixed them into pieces.

Zhang Chao's eyes kept staring at Lin Feng, with a sneer on his face, if the herbs do not blend with the base material, there will be no medicinal properties, this truth is understood as long as people who make skin care products, but Lin Feng does grind the herbs himself and let another person make the base material, there is no appearance of wanting to fuse, no matter how you look at it, he is also a layman.

The surrounding researchers whispered, and when they saw Lin Feng's approach, they all shook their heads, becoming more and more optimistic about this young man.

Cheng Yanling also found a problem, leaned her head over, and said softly, "Mr. Lin, aren't you going to put the medicinal herbs in earlier?"

"It's not time yet, put it in now, the effect of the medicine will be reduced. Lin Feng smiled and said.

Seeing that Lin Feng was so serious, Cheng Yanling didn't want to say it anymore, but she was secretly worried in her heart, hoping that Lin Feng could succeed.

After grinding the herb into powder, throw it into a decoction pot, add some water, and simmer over low heat.

It didn't take long for a bitter taste to appear in the air, reminiscent of the childhood experience of drinking Chinese medicine.

After Lin Feng estimated that the time was about the same, he put the medicinal juice in the pot into a porcelain bowl to cool.

The next steps are relatively simple, after the base material is made into water emulsion, Lin Feng drops a few drops of the potion in it, then sprinkles some medicinal powder, and stirs well.

The white water milk quickly turned brown, Lin Feng picked up the finished product, smiled and said, "Okay, it's done." ”

Zhang Chao sneered, pointed to the finished product and mocked: "Look what this is? It's the same as, that normal person would use such a beauty product?"

The people around nodded one after another, just this appearance is really not good, the general whitening milk is white, so as to achieve the whitening effect, change the brown, isn't that worse and worse, making the complexion worse?

Seeing the appearance of these people, Cheng Yanling felt a little bottomless, so Zhang Chao said that it was okay, if everyone felt that there was a problem, then this product was indeed defective.

She glanced at Lin Feng, who was calm and composed, sighed lightly, and began to wonder if the other party would make whitening products.

"Don't worry, this thing still depends on the effect. Lin Feng put the small porcelain bowl on the experimental table and said lightly.

Seeing the other party's confident expression, Zhang Chao was angry, patted the people around him, and said: "Xiao Yan, try it in the past, let this young man die of this heart, the things produced by our company are not so simple to make." ”

The researcher named Xiao Yan nodded and came to Lin Feng's side.

He did have the qualifications to test the medicine, and his exposed arms were a pale brown color, and it seemed that he often went out and was exposed to the sun.

The onlookers immediately opened their eyes wide and looked at the two of them, they all knew that color was only secondary, the key to the product was the medicinal effect, if it could really achieve the whitening effect, the product was black, and those women would also compete to use it first.

Lin Feng put the product in Xiao Yan's hand and said, "The method of use is very simple, apply it to your skin. ”

Taking the small porcelain bowl, Xiao Yan did as he was told, smeared some medicinal milk, and applied it to his left arm.

It was only a few seconds after taking the medicine, Xiao Yan frowned slightly, and said, "There is a slight tingling sensation, and there are other sensations, I can't say it." ”

As soon as these words were said, the audience was in an uproar, and the stinging sensation meant that everyone present knew very well in their hearts, and the corners of Zhang Chao's mouth rose wildly, and sure enough, what this young man made could not be used at all.

The most taboo thing in skin care products is allergic reactions, and a slight tingling sensation is a precursor to allergic reactions.

Cheng Yanling covered her forehead, her face was full of disappointment, it seems that the man in front of her, although he is a famous doctor, is not proficient in everything, the key is that he just gambled with someone in public, and this face has been lost.

Zhang Chao, who was full of smiles, glanced at Cheng Yanling and said to Xiao Yan: "Erase the paper, hurry up and wash it." ”

"Wait a minute, I said, three minutes. Lin Feng still has the same smiling face, and it has never changed.
