Just when Wang Zhuoran was a little desperate, he accidentally found a small notice in the newspaper, which was the advertisement for Afa's recruitment assistant. For Wang Zhuoran, it was like a fallen water grabbing a life-saving straw. He immediately came to the interview with a passionate mood.

A 17-year-old thin boy came in from outside the door. Ah Fa looked up and down until he felt a little uneasy when he realized that he was a little rude.

"Come on, little brother, sit down and talk." No matter what, you have to try it when you come. Ah Fa smiled and greeted him, and then ordered Xiaoqin, who was doing the trick, "Pour tea and get fruit."

Wang Zhuoran entered the house, sat down a little crampedly, and secretly looked at the fake foreigner who had no braids. The fake foreigner was very tall and seemed to have no aura of a scholar. He therefore suspected that this guy was really doing a chemical experiment.

Ah Fa smiled faintly and said, "Are you a student of Guangfang Dialect Museum?"

"Yes, Mr. Chen." Wang Zhuoran replied quickly: "I heard that you are going to recruit an assistant for chemistry experiments, so I'll give it a try."

Ah Fa nodded and continued to ask, "What should you do with your studies? I mean, I need a full-time assistant, not the kind that I can only come in my spare time."

Wang Zhuoran hesitated for a moment and answered truthfully: "Guangfangyan Pavilion is about to close. Oh, it's not about closing, but changing the brand and re-enrolling students. We are about to be dismissed. But I like the science of chemistry very much. If I can find a corresponding job, I am very willing."

Caifeng walked in, put the tea and fruit on the table, and then walked out slowly.

Ah Fa had asked several questions and felt that the general situation had been understood, so he smiled and signaled Wang Zhuoran to drink tea and eat fruit, and said, "Don't be polite, drink some hot tea and eat some fruit."

"Your official words are so good." Wang Zhuoran also relaxed a lot and said after taking a sip of tea.

Ah Fa smiled faintly, tapped his fingers on the armrest of the chair twice, and said, "Where are we, because both parties don't know each other very well, we will set a tentative trial period. You and I will adapt to each other. If you feel that it is not satisfactory, you can leave. If I think you are not suitable, I think you are not suitable."

"I understand." Wang Zhuoran nodded. This fake foreigner was very skillful in doing things.

"Okay, let's go to the laboratory to take a look later." Ah Fa nodded with a smile. He had to see the young man's abilities with his own eyes before he could feel at ease. Moreover, observing his temper is also a key factor in whether he can be left behind.

Two days later, Wang Zhuoran moved over and immediately devoted himself to the chemical experiment he loved and was responsible for nighttime updates. According to the experimental steps designed by Afa, the two began to work hard to produce odorants.

In just one day, Wang Zhuoran felt that this time was really lucky. Not only did he earn six yuan a week, but Ah Fa's theoretical level seemed to be much higher than the "foreign teaching" in the Guangfang Dialect Museum, and he had never seen some experimental techniques before. It can be said that he found an excellent chemistry teacher who paid for it.

Filter the flour and extract the gluten. Then put the gluten into a container, add an appropriate amount of hydrochloric acid and heat it to hydrolyze. After the gluten hydrolyzes and becomes liquid, filter it, and then vacuum filtration to reduce the acidic ingredients to a certain extent and become solid.

Then add alkaline water to the solid gluten to neutralize the remaining acid and make the gluten transparent. Filter it with charcoal again to remove the original pigment of the flour. Add alcohol to the liquid gluten, and then precipitates begin to appear. Finally, the precipitates are placed in a centrifuge to fluctuate, so that the alcohol evaporates, and white crystalline granular odorants are obtained.

The steps are so simple, but it only requires multiple experiments to establish accurate data records, including the quantity, purity, and reaction time of the reagents to achieve the best results. With the help of Wang Zhuoran and the correct method of Afa, the work of extracting odorants has progressed quickly, and Afa knew that success was getting closer and closer to him.

But Afa also has another concern, that is, the sales of phenolic acid. Transferring the experimental results to industrial production, mass production, and putting them into the market, this series of operations should not be a problem based on his current funds. However, it is not so easy to establish a sales network, promote phenolic acid to thousands of households, and then to the whole country, and even Asia.

Connections are another flaw of Afa, and it is not easy to make up for. One is not famous, the other is not powerful. Although he is the manager of the so-called agency company, he is still far from contacting the circle of real Shanghai business people! Therefore, while paying attention to the ready-made resources available, Afa began to focus on the land he bought. If he spread such a big stall, it will naturally attract attention and this reputation will naturally rise.

…………

Half a month later.

"Bang!" With a sound, the huge door was opened, which scared Ah Fa. Then Wang Zhuoran ran in with an excited and hoarse voice. He reached in with a loud voice, stretched a small paper bag in his hand to Ah Fa like offering treasures, and shouted excitedly: "Sir, Mr. Chen, it's successful, it's successful, it's made."

Ah Fa took the paper packet in surprise and opened it. There were a few grams of white crystal particles inside. He stretched out his fingers and dipped it in his mouth. Well, it was the taste, which was extremely delicious. He widened his eyes, smacked his lips, slowly raised his head, looked at Wang Zhuoran's unkempt appearance, looked at his expectation and a little nervous look, and suddenly gave Wang Zhuoran a hug.

"Haha, yes, it's it." Ah Fa almost jumped up happily. Although he knew that the production of phenolic was almost successful, he did not expect it to be so fast.

"Good boy, good boy, have a promising future." Ah Fa touched Wang Zhuoran's hair with his hands, looked at his blood-filled eyes, and his clothes that were corroded by acid, and praised him repeatedly, "Great, amazing, you have made the world's first phenolic, which is so amazing."

Wang Zhuoran stepped back embarrassedly, avoided Ah Fa's clutch, and said modestly: "I am just the executor of the steps formulated by Mr. I should be attributed to Mr. All of this."

"Very good, very good." Ah Fa praised Wang Zhuoran's simple quality of not being arrogant. He patted his shoulder and said, "Go and clean up. Let's go out to eat tonight, which is a small reward for you."
