It's 11 p.m.

The campus of No. 2 Middle School was completely quiet. Evening self-study had long ended, and even the most diligent top students had returned to their dormitories.

Lights out is at 10:30, so the main lights aren't on in the dorm rooms. Only through the curtains can you see the faint light from some of the desk lamps.

The dormitory supervisors had already closed the dormitory doors and were ready to clean up on their own.

The entire No. 2 Middle School campus was eerily quiet.

An enclosed electric tricycle drove up to the back gate of the Second Middle School. The driver handed a note to the security guard, who glanced at it and let him pass.

The electric scooter drove straight to the teaching building and stopped in front of the nearest orange juice stand.

A person got off the car carrying two large round buckets, one transparent and one opaque.

The back of the machine was opened with a key, and the man operated it for a while, pouring all the pulp from juicing the oranges into the large, opaque bucket. This pulp is excellent for use as fertilizer. He then opened another container inside the machine, which was filled to the brim with orange juice.

The orange juice was poured into the large, round, transparent container that had been brought along.

The freshly squeezed orange juice is collected on the same day, concentrated, and then added to beverages. After all, orange juice drinks need to undergo quality inspection, and those that do not meet a certain percentage of juice content will not pass.

But the products produced by these orange juice machines do not require this.

After doing all this, the person checked the other supplies in the machine, added a bag of oranges, filled the water tank, closed the back door of the machine again, and moved on to the next juicer.

The sales data for each juicer can be directly transmitted to the company's sales control center. Therefore, the sales control center has a detailed plan for when raw materials need to be added and whether waste residue and finished products can be recycled.

Everything proceeded smoothly, and before noon, the enclosed electric tricycle returned fully loaded.

Meanwhile, the more than 200 machines deployed in various areas of Lingcheng and the ten enclosed electric tricycles that were dispatched all returned to the distribution center around noon.

Because the machines are just being installed, the current output is only enough to fill a small gap. However, practice has shown that Liu's orange juice machine model is widely accepted.

Students' money is especially easy to make, and the orange juice machines installed in several schools have the highest sales volume.

Of course, in the early stages, to build a good reputation, the machine was set to mix 50% freshly squeezed orange juice with water to produce the orange juice, while the other half was the recycled "finished product." If all goes well, Mr. Liu's ultimate goal is to reduce this initial ratio to 10%, which would increase profits fivefold.

......

......

The most painful thing in life is being the only one who is sober when everyone else is drunk.

By the afternoon of the following day, Mr. Liu's orange juice machines had been installed in the dormitory area of ​​No. 2 Middle School, indicating that sales were indeed booming.

Although dormitories are not prohibited from bringing snacks and drinks like the teaching area, buying a cup of freshly squeezed orange juice in the dormitory area actually gives you a laundry coin. Although it is only worth one yuan, it is enough to make students who were planning to get a cup flock to it.

Li Lechen passed by the two orange juice machines next to the laundry room twice within an hour, and according to the counters on the machines, they had already sold over a hundred cups. Even the laundry room wasn't doing that well.

Li Lechen will no longer buy orange juice from Master Liu's orange juice machine unless required for an experiment.

Last night's comparative experiment showed that the orange juice from Liu's "super food purifier" was significantly different in concentration from the half-eaten juice. The half-eaten juice tasted almost like sugar water.

There might be a little orange juice, but definitely not the whole glass.

Li Lechen was very excited about this exciting discovery. If he had a megaphone, he would want to announce it to the world.

But then he discovered the key to the problem: besides this "super food purifier" from the future, what reason did he have to question whether there was anything wrong with the orange juice coming out of Master Liu's orange juice machine?

It might be possible through professional testing, but one's own theoretical basis would be insufficient.

Thinking back to the food poisoning incident the day before yesterday, a classmate was reported to the whole school for spreading false information simply because he forwarded the facts using his uncle's alternate account. If I were to jump out and say that there was something wrong with Master Liu's orange juice, but I couldn't provide solid evidence, I would definitely be escalated to a major issue.

Li Lechen couldn't concentrate on any of his classes that morning—one math class, two physics classes, and one Chinese class. More importantly, he couldn't understand a thing.

Even so, he still showed off during the last Chinese class.

For no other reason than that if the Chinese teacher doesn't show off, they'll definitely make a big deal out of it, just like the English teacher, by focusing on their poor performance in humanities subjects.

There's nothing I can do about it; I was definitely a terrible student back then.

Li Lechen really couldn't understand why, in today's world where the internet is so developed, students would still be forced to memorize classical Chinese texts.

What's the point of memorizing it? You'll just throw it away after the exam anyway, won't you?

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

Scan one article and press once, then scan another article and press once more.

This speed is much faster than reading ten lines at a glance. Most importantly, it requires absolute photographic memory.

Then, in full view of everyone, less than fifteen minutes into the last Chinese class, Li Lechen lay down and fell asleep.

Although he had been lying down or propping his head up in the previous three classes.

But this was the first time he had ever dealt with the Chinese language teacher of the top class.

Similarly, the Chinese teacher had heard a great deal about Li Lechen, and today was the first day that she met him face-to-face in class.

"Li, you're not feeling well. You can go back to your dorm to rest." The Chinese teacher tentatively woke Li Lechen, who was actually just deep in thought, and then said insincerely, "If you're not feeling well, you can go back to your dorm to rest."

"Teacher, I'm not feeling unwell. I just know all of these things, so I'm spacing out for a bit."

"You've mastered it all?"

As expected of a Chinese teacher, the emphasized "all" fully expressed her disbelief.

"Don't even mention memorizing it, I can recite it from memory, you can test me," Li Lechen said innocently, defiantly.

"Try to recite 'Ode to the Red Cliff' from memory and let me see!"

The Chinese teacher immediately set a question.

Among the 72 required classical Chinese poems, "Ode to the Red Cliff" is considered quite difficult. This Chinese language teacher, who has taught five or six classes of top students, knows very well that these students are mostly excellent in science and can generally handle humanities subjects. Although some have exceptional memories, they generally disdain memorizing such poems.

Filling in blanks in classical Chinese poems is often a major source of lost points for these top students, so the Chinese teacher emphasizes the importance of memorizing classical poems in every class of top students.

Today, someone actually challenged themselves to recite 72 classical Chinese poems from memory. The Chinese language teacher really needs to see this.
