Li Zheng thought that he could use school resources and had a shuttle bus, but he thought too much.

Yu Hong just threw him a WeChat business card and played with it himself.

Li Zheng asked if he could go by taxi with public funds, and Yu Hong asked him to ask President Liu.

Li Zheng knocked into the principal's office again and asked Principal Liu if he could take a taxi. The principal asked Yu Hong.

Li Zheng, who is about to turn 18, feels the hypocrisy of this world for the first time.

Our Yinghu fishing gang can only strengthen itself.

Fortunately, WeChat contacts are very reliable.

It is a big sister nicknamed "Simigle". Thistle is studying for a master's degree. The head is a large regular crystal with a crack in the center like a snowflake, full of chemical beauty.

The elder sister was also very enthusiastic, and soon passed the verification of a friend, and sent the address of [Jijing University School of Chemistry and Molecular Engineering] to Li Zheng, asking him how long he could arrive.

Li Zheng estimated that it will take about 50 minutes, and then play a surplus of 20 minutes, finally set at 9:15.

After that, it was a subway journey. Line 2 changed to Line 4 and sat all the way to Jida East Gate.

In the middle, Li Zheng took out the experimental textbook and reviewed it a little bit. The effect is still limited, and the right should strengthen the memory.

The journey was smoother than that given by the map software. Less than 9 o'clock, Li Zheng walked out of the subway and was standing directly opposite the Jida East Gate.

Looking at the past, the East Gate of thistle is not big, just like an ordinary unit. At this time, only a small door was opened. There are not many people coming and going, and you need to show your ID to enter.

Looked at the small flat heads with their shoulders in and out.

Li Zheng knew that they were all big brothers.

If he had more time, he really wanted to get in and see the legendary Anonymous Lake, but at this moment, he could only go south along the road.

There is no way, because Anonymous Lake is too large, and there are too many public pools. The Jidahua College has already moved out of the campus, just about 200 meters in front of the road.

But when Li Zheng was halfway through.

Suddenly glared.

Mentioned an anus.

Damn... I didn't stop last night, I ate too much spicy stuff.

Why is it happening now?

He looked around quickly.

Just right, there is a public toilet at the intersection.

Li Zheng couldn't think about it for a long time, forcedly shut it down, ran into it, and rushed into the men's toilet.

Although this is a small public toilet, it also has two compartments, and the door outside is now open.

Li Zheng didn't have time to think about it. He quickly drilled in, closed the door, hung up his schoolbag, and put down his trousers for a while.

Then, Chang sighed with relief.

saved.

The rest, take your time, there is no need to be so intense.

But he had just slowed down, and next door was Ku Ku Ku Ku.

The grudge is the same.

Li Zheng didn't even think that it was like yawning, and it was also contagious.

As soon as he next door got up, he also rose fiercely, turning over the river.

Take a look at the two of you and promote each other. In just two minutes, you have completed the ten-minute project.

Li Zheng is also rarely so smooth, thinking that the hero next door must be the same, it is inevitable that there is some anger.

It's a pity that people are now living in buildings and have separate toilets. I'm afraid they can't enjoy this kind of pleasure anymore.

After expressing his emotions, he unzipped the schoolbag and pulled out the tissue.

Then he stared.

I clearly remember most of them.

How can I get one?

I think of the special situation of flying stars today.

This is a bit more difficult to handle.

no way.

Fold it a few times.

Better than nothing.

While Li Zheng was calculating how to use this piece of paper, a slightly immature voice-changing male voice came from next door.

"Are you..."

Li Zheng was shocked.

Is it the hero next door?

Still a young hero.

"Huh?" Li Zheng immediately responded to him.

The young hero paused for a moment, and asked with some embarrassment: "Inside...brother...how much paper..."

Li Zheng suddenly panicked and looked into the palm of his hand. The thin tissue that was a little larger than the palm of his hand responded stiffly, "I... just one..."

"Hey..." the young hero sighed painfully. "Walking while walking, suddenly suddenly... You are too?"

Li Zheng felt the same, and sighed, "Yes, this kind of thing is always unprepared."

"Like love." The next door also sighed.

"..."

"..."

"Good... literary talent."

"Thank you, thank you, that... you... wipe it, leave me alone..."

Looking at the only piece of paper in his hand, Li Zheng wondered: "Otherwise, I will finish it soon and go out and buy some paper for you?"

"Don't... it's too much trouble for you..." The young hero only gritted his teeth, gurgling, "Don't worry about me, I will figure it out for myself."

Li Zheng shivered.

No hero.

Thinking of everyone's encounter with Ping Shi, a fate, Li Zheng also gritted his teeth, biting the same gurgling.

"I'll tear you half, we both save a little."

"Farewell...you are not enough..." the hero retorted.

"It's okay. I'm good at math and can calculate the maximum usage rate." Li Zheng said, turning the ruler out of the schoolbag, folding the paper towel in half and holding the ruler in preparation for cutting.

"Ah, I'm not bad at math." The hero next door seemed to be ignited. "Brother, tell me the length and width of the paper quickly, and I'll count it for you."

"Oh? Interesting." Li Zheng thought of this, and did not rush to cut, first measured it, "18X18 cm, original folding method, 3X4, 12 grids."

The hero then pondered: "Well... if these 12 squares can be fully utilized, it is barely enough to rub 6 times per person."

"Yes, but if it is folded in half, the number of times of use will be halved." Li Zheng frowned, "And also consider the hands and buttocks, not to be touched."

"In this way... I seem to have seen this origami problem." The hero suddenly raised his voice. "I remembered, the solar panel of the satellite, because it was going to fold and unfold, it seemed that there was an algorithm, etc. Wait for me to check."

On this issue, Li Zheng is more biased towards the pragmatists, and tries repeatedly with the paper in his hands.

Not many times, the hero knocked off the partition: "The length of the paper is L, and the thickness of the paper is t, then L=πt/6 times 2 to the nth power plus four, and then times 2 to the nth power minus one, this n is The maximum number of origami times, we can calculate it almost as a log

Li Zheng whispered: "Miao is wonderful, but this seems to be a simple discussion of how many times the paper can be folded? We still have to discuss the area used each time and how to avoid sticking hands."

"Yeah... These solutions are not reliable. Has anyone studied such an important mathematical problem?"

"I have a curved plan to save the country." Li Zheng swallowed and said, "Fingers go directly through the middle of the paper, and then use your fingers... After finishing things, wrap around, and suddenly, wipe your fingers Net, throw it away, what do you think?"

"This... is also a solution, but the loss is a bit big." After the hero finished, he suddenly had a plan. "Brother, we can wipe it at the edge, and then fold a small part of it. Go in, change the edge, wipe again, roll the paper in a little bit, and finally turn into a ball."

"Wonderful!" After Li Zheng praised, suddenly came to inspiration, "I think it can be strengthened, with an angle α..."

"It's okay, but it can be optimized. After calculating α, put the diagonal..."

"Well, it's interesting... but are we going to leave at least a few square centimeters of operating space for our fingers?"

"Oh, I forgot to think about it. After all, the usage rate of toilet paper is inversely proportional to the usage rate of finger shit..."

After ten minutes.

"Yes, that's it, you can start it!" Hero said, "so that each of us can use it 7 times, but we can't get it."

"Well, I'll draw an inscribed circle as an angle..." Li Zheng just wanted to get the pen, and it always felt wrong, and he knocked on the partition. "Brother...Since it's so troublesome, I'll just put this Is the sheet of paper folded in half vertically and horizontally and cut into 16 small squares?

"Ah!" The hero slapped his head, "Yeah, every time I threw it away with a cube, okay brother."

"Then I cut?"

"Please." The hero sneered. "As soon as we discussed mathematics, we got stuck. The brother laughed."

Li Zheng also smiled: "Me too, you see my compasses are drawn."

"In this way...the compass seems to be useful..."

"To...brother here."

Because it takes too long.

When the last two were used.

It’s basically done.

But this does not hinder the academic enthusiasm between them.

Greet each other while wiping hard.

The hero asked diligently: "Speaking of brother, you're so furious."

"Eh, I ate too much stinky tofu last night, sorry."

"I'm fucking, no wonder." The hero then asked, "Brother, are you thistle? So strong."

"I was a sophomore, just passing by."

"It's so coincident that I am also a sophomore." The hero suddenly remembered something. "Did you not attend high school this Tuesday?"

"In class, I have something to come here."

"It's so coincident that I also have something..." The hero's voice trembles gradually, "Aren't you going to... this is Jihua Dahuan?"

"Yeah." Li Zheng exclaimed, "You wouldn't... also be competitive?"

"Yeah!" The hero was completely excited. "Are you contacting Mr. Simig?"

"Yes."

"You... wouldn't you be..." said the hero impatiently, "Li Zheng??"

"Fuck!" Li Zheng thumped the door in shock, "Shi Yang??"

"Is this okay?" The hero was overjoyed, "I thought I would meet you!"

"Who's not!" Li Zheng also wiped hard, "Don't say, wipe quickly."

Li Zheng, Ku Xia Ku Xia, used up eight small pieces of paper, retired from the whole body, brewing emotions, and slowly opened the door of the single room.

The door hadn't opened yet, and there was a man's mourning voice outside.

"Two big brothers, please, please come soon!"

Li Zheng hurriedly opened the door and flashed quickly with his head down.

He only felt a gust of wind passing by his ear, and the man rushed into the single room.

The door "Bang" hit it all at once, and almost at the same time, there was a loud sound inside.

The hero next door sighed: "You are also happy enough."

"Happily, you horse..." The man burst out his mouth and gritted his teeth. "Leather... The belt buckle is stuck."

This voice is not only angry, but also secretly endless grief and humiliation.

Li Zheng didn't dare to think about it, quickly walked out of his backpack and washed his hands quickly.

The next-door hero also rushed out with his pants on, and washed with Li Zheng side by side: "Quickly withdraw quickly..."

"Yes... don't wait for him to come out..."
