Eleven o'clock in the evening.

The campus of No. 2 Middle School has been completely quiet, the night self-study has long ended, and even the hard-working students have returned to the dormitory.

The lights went out at half past ten, so there were no headlights in the bedroom. Only through the curtains can be seen that some of the bedrooms are still faintly lit by table lamps.

The dormitory aunts had already closed the door of the dormitory, ready to brush themselves.

The entire campus of No. 2 Middle School is a quiet one.

An enclosed electric tricycle drove to the back door of No. 2 Middle School, and the driver handed the security guard a note, and the security guard took a look at it and let him go.

The electric car drove directly to the school building and stopped in front of the nearest first orange juice.

A man got out of the car, carrying two round vats, one transparent and one opaque.

The back wall of the machine was opened with a key, and the man manipulation poured all the orange juice into the opaque vat. This slag is super good for use as fertilizer. Then he opened another jar in the machine, which was full of orange juice.

The orange juice was poured into the large, round, transparent vat that had been brought with us.

These freshly squeezed orange juices are collected on the same day and can be concentrated and added to the drink, after all, orange juice drinks need to be quality checked, and it is not possible to pass the juice content if it does not reach a certain percentage.

But these orange juice machines don't need to produce products.

After doing all this, the visitor checked the stock of other things in the machine, added a bag of oranges to it, filled the tank with water, and then closed the back door of the machine again and moved on to the next juicer.

The sales of each juicer can be directly transmitted to the company's sales control center, so when it is necessary to come over to add raw materials, whether the waste residue and finished products can be recycled, the sales control center has a detailed plan.

Everything went in an orderly manner, and before twelve o'clock, the enclosed electric tricycle was fully loaded.

At the same time, more than 200 machines and 10 enclosed electric tricycles deployed in various areas of Lingcheng returned to the distribution center at about 12 o'clock.

Because the machine has just begun to be laid, this finished product is only enough to plug the teeth. However, practice has proved that the model of Master Liu's orange juice machine is highly accepted.

In particular, the students' money is very profitable, and the orange juice machines laid in several schools have the highest sales.

Of course, in the early stage, in order to save word of mouth, the machine is set to use 50% freshly squeezed orange juice plus blended water to become orange juice, and the other half of the orange juice is the so-called "finished product" that is recycled. If all goes well, Master Liu's ultimate goal is to reduce this initial percentage to 10%, and then the profit can be increased by five times.

......

......

The most painful thing in life is that everyone is drunk and I am sober.

By the afternoon of the next day, Master Liu's orange juice machine had been rolled into the dormitory area of No. 2 Middle School, and it seemed that the sales were really hot.

Although snacks and drinks are not allowed in the dormitory like in the teaching area, buying a cup of freshly squeezed orange juice in the dormitory area will actually give you a laundry coin, although it is only worth one dollar, it is enough to make students who are ready to have a cup rush to it.

As for the two orange juice machines next to the laundry room, Li Lechen passed by twice an hour before and after, and according to the counter on the orange juice machine, more than 100 cups had been sold. Even the laundry business is not so good.

Li Lechen will not buy the orange juice in Master Liu's orange juice machine anymore, unless the experiment requires it.

In last night's comparison experiment, the orange juice of Master Liu that came out of the "super food purifier" was half of the comparison, and the orange concentration difference was not a little bit, and when you took a sip, it was almost the taste of sugar water.

Orange juice, maybe a little, but definitely not in the whole glass.

Such a powerful discovery, Li Lechen was very excited for a while, if there was a loudspeaker, he wanted to tell the world.

But then he found out the crux of the problem: apart from this "super food purifier" from the future, what reason did he have to question the problem with the orange juice coming out of Master Liu's orange juice machine?

Maybe it can be done through professional testing, but its own theoretical basis is not sufficient.

Thinking of the food poisoning incident the day before yesterday, a certain student just used his uncle's trumpet to forward the truth, and was notified to the whole school on the charge of spreading false statements.

A whole morning class, one math, two physics, and one Chinese, Li Lechen didn't bother to listen. Of course, it is more important to not understand it at all.

But even so, he showed off in his last Chinese class.

Not for anything else, just because if you don't show off, this Chinese teacher will definitely be like an English teacher, blaming himself for not being good at liberal arts, and then making a big fuss.

No way, who let himself be a scumbag in the past.

In other words, Li Lechen really can't understand why he wants students to recite ancient texts pervertedly when the Internet is so developed today?

What's the use of remembering? Isn't it just throwing it away after the test?

So after the teacher listed the 72 ancient texts that needed to be memorized, Li Lechen put on his black-rimmed glasses.

Scan one and press again, scan and press again.

This speed is much faster than ten lines at a glance. The most important thing is to be absolutely unforgettable.

Then, in full view of everyone, Li Lechen fell asleep less than 15 minutes after the last Chinese class started.

Although in the previous three classes, he was almost either lying on his stomach or with his head on the pestle.

But the Chinese teacher of the top class, he is dealing with it for the first time.

Similarly, this Chinese teacher is also familiar with Li Lechen's name, and today is the first day to meet him face-to-face in class.

"Mr. Li. The Chinese teacher tentatively woke up Li Lechen, who was actually just contemplating, and then said hypocritically, "If you are not feeling well, you can go back to the dormitory to rest." ”

"Teacher, I'm not unwell, it's just that I'll be able to do all of this, so I'll be stunned for a while. ”

"It's all going to be?"

The Chinese teacher deserves to be a Chinese teacher, and an aggravated "all" fully expresses her disbelief.

"Don't say you can memorize, you can write silently, you can check it. Li Lechen innocently provoked.

""Chibi Fu", you write one silently and I'll take a look!"

The Chinese teacher immediately asked the question.

Among the 72 ancient poems that must be memorized, "Red Cliff Fu" is quite difficult. This Chinese teacher has taught five or six top classes, and knows very well that most of these top students are very good at science and can basically stand up to the liberal arts. Although there are many people with super memory, they generally don't bother to memorize this.

Filling in the blanks of ancient poems is often the hardest hit area for these top students to lose points, so this Chinese teacher must emphasize the importance of memorizing ancient poems in every top class.

Today, someone directly challenged to be able to write 72 ancient poems silently, and the Chinese teacher really wanted to see it.
