After settling these silly boys, it was already noon.

Zhu Youzhen had just gone downstairs, and the Ruyi Building was already full.

Several guests crowded in front of the counter and said eagerly: "Is there even a place in the lobby?" Otherwise, you can share a table. ”

Liuli, who was dressed in a water blue round-necked long fan, listened quietly, then pursed her lips and smiled slightly, and said politely: "The small shop is open for business, and there is no rule for throwing customers out." It's not that the little woman is unreasonable, it's just that even the table is gone, if you really want to eat in Ruyi Building, you can leave your name, and come at noon tomorrow. ”

Several of them are merchants from other places, and when they heard that the dishes of Ruyi Lou are the best in the world, they rushed to taste them in a hurry, and they couldn't wait for tomorrow, so they had to leave.

The remaining two have no choice but to register their names and come back tomorrow.

During the whole process, they behaved in a proper manner and did not dare to make the slightest radical move.

At the door stood the restaurant of Jinyi Wei Qianhu, who ate the bear's heart and leopard gall, and dared to make trouble here.

Liuli's methods are relaxed, and several waves of guests have been easily sent away by her, and she must not offend anyone, she is indeed a rare talent.

Seeing Zhu Youzhen coming down from upstairs, Liuli brushed the tips of her hair and walked up with a smile.

"Business is good, and I saw a few waves of disappointed guests downstairs."

Liuli said with some regret: "The private room in Ruyi Building has been lined up for eight months, if it weren't for the lobby not allowing reservations, many people wouldn't be able to eat even if they came early." If it weren't for the limited table, the monthly profit would be 30% more. ”

Ruyilou used to make a monthly profit of 2,000 taels, but after the introduction of Sprite and other drinks, the monthly profit reached 2,500 taels.

More than 30%, that is, the monthly profit is 750 taels more, about 56 catties of silver, which is enough for a small household in the capital to live a life of food and clothing for 20 years.

Zhu Youzhen thought for a while, "The signboard of Ruyi Building has been erected, and it is impossible to add more tables." Instead, you can try to buy the store next to it and expand it after opening it. ”

Liuli shook her head and said disappointedly: "I have already talked about it, and the owners of the two shops next to it are unwilling to sell." Our Ruyi Building's business is good, and it should be good for them, and no one wants to dry up and fish. ”

"It's not a problem to have a little more silver." Zhu Youzhen also thought that the other party disliked the silver and gave too little.

"One of them was okay and was able to loosen up a bit. But the rest of the family, as if they had an enmity with us, did not want to talk about it. ”

"Is it so awesome? Since people don't want to, we don't force it, let's talk to another family first. Zhu Youzhen said disapprovingly.

Liuli knows his son-in-law's style of doing things, and he respects a ruler when people respect him, and he doesn't like to bully people the most.

Fortunately, one of them is willing to have intentions, which can alleviate the dilemma of insufficient space in Ruyi Building.

This matter was handed over to Liuli, and Zhu Youzhen was still very relieved.

After he explained the incident, he went into the backyard.

A room has been vacated in the backyard for Li Kaiji's research.

In order to make medicine, it was filled with the smell of herbs, and Li Kaiji would cook gauze with hot water every time, and after drying it, he would add herbs to compress the buttocks of several nobles.

And the most important of these is the distiller designed and made by the Emperor of the Apocalypse, which can purify allicin, and has many other wonderful uses.

There were several large jars piled up in one corner of the room, and when Zhu Youzhen opened the stopper, a strong smell of wine came to his face.

This is not a strong liquor, but a very strong alcohol.

"How many sets of experiments have you done to inhibit bacteria with alcohol?" Zhu Youzhen turned around and asked.

Li Kaiji followed behind with a small notebook, and hurriedly said: "The students did ten groups and repeated more than 100 times. Sure enough, as Master said, it is not that the higher the alcohol concentration, the better the sterilization effect. ”

After speaking, he looked at Zhu Youzhen with adoring eyes, and asked carefully: "But the apprentice is stupid, and he can't figure it out." ”

"Keen and studious, not ashamed to ask, just ask whatever you want." Zhu Youzhen took care of everything.

"It stands to reason that alcohol can kill bacteria, isn't it better to have a better alcohol concentration?"

In fact, this knowledge is not only known to Li Kaiji, but also to many people in later generations.

Zhu Youzhen sat down and explained with a good face: "That's because you know that alcohol can sterilize, but you don't know how it kills." ”

"Please also ask Master for advice."

Zhu Youzhen coughed lightly, and a feeling of being a teacher arose.

Recalling some knowledge points he had seen in his previous life, he easily explained: "The reason why alcohol can kill bacteria is because alcohol infiltrates and takes away the water in the bacterial protein and kills bacteria." High concentrations of alcohol form a thin film on the surface of the bacteria, preventing the alcohol from penetrating. The low concentration of alcohol is not enough to kill bacteria, and only a certain concentration of alcohol can completely kill alcohol. ”

Li Kaiji recorded in the small notebook with a thirst for knowledge on his face, and asked without raising his head: "Dare to ask Master, what is protein?" ”

Zhu Youzhen thought about it, this knowledge point was a little vague, so he had to say perfunctorily: "Protein is a substance that makes up bacteria. ”

"What is matter?"

"Why do bacteria need proteins?"

"What the hell is protein for?"

Li Kaiji's eyes widened and he looked at Zhu Youzhen intently.

With so many questions, it is still difficult to answer, Zhu Youzhen was directly dumbfounded.

Even if I have completed my university education, I am not a biology major, so how can I know so clearly.

"Master, what's wrong with you?"

Li Kaiji didn't expect that his master didn't know at all, and when he saw that he didn't answer, he asked with a puzzled expression.

Zhu Youzhen coughed embarrassedly, he finally understood why the teacher in his previous life left in a hurry after class.

is a student who is not ashamed to ask this kind of question, who is still a top student, who is not empty in his heart.

"Kaiji, what you get on paper is shallow, and you never know that you have to do it."

"Master can't always be by your side and answer your questions. Isn't it true that if I'm not here, you won't study and study? So the rest of the questions need to be studied by yourself, and this is the test left to you by Master. Zhu Youzhen said solemnly.
