Chapter 129

Li Zheng thought that he could use the resources of the school, and there was a special bus to meet him, but he thought too much.

Yu Hong just threw him a wechat business card and played it by himself.

Li Zheng asked if he could take a taxi with public funds. Yu Hong asked him to ask President Liu.

Li Zheng knocked into the headmaster's office again and asked if President Liu could take a taxi. The principal said to ask Yu Hong.

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

Our Yinghu fishing gang can only improve ourselves.

Fortunately, wechat contacts are very reliable.

Jida is a big sister, nicknamed "ximig". Jida is studying for a master's degree. Her head is a large regular crystal with a crack like a snowflake in the center, which is full of chemical beauty.

The elder sister was also very enthusiastic, and soon passed the verification of her friend. She sent the address of School of chemistry and molecular engineering of Jijing university to Li Zheng and asked how long he could arrive.

Li Zheng roughly estimated that it would take about 50 minutes, and then 20 minutes to get rich. Finally, it was set at 9:15.

After that, it is the subway journey, line 2 to line 4, all the way to Jida east gate.

In the middle, Li Zheng took out the experimental teaching material and reviewed it a little, but the effect was still limited.

The distance was smoother than the map software gave. Before 9 o'clock, Li Zheng got out of the subway and was standing opposite the east gate of Jida.

At this time, it's just like ordinary people who don't know how to get into the East. They just need to show more than one identity card to enter.

Looking at those small flat heads with shoulders in and out.

Li Zheng knows that they are all big men.

If he had more time, he would really like to go in and see the legendary lake, but for now, he could only go south along the road.

I can't help it. Because the anonymous lake covers too much land and there are too many public stalls, jidahua college has already moved out of the school, just 200 meters ahead of the road.

But when Li Zheng was halfway there.

All of a sudden, his eyes glared.

He raised his anus.

Damn it I didn't stop last night. I had too much spicy food.

What's the matter now.

He looked around eagerly.

Just right. There's a toilet at the intersection.

Li Zheng didn't think much about it. He forced him to close it and ran into the men's room.

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

Li zhenggen couldn't think at all. He quickly went in, closed the door, hung up his schoolbag and put down his trousers.

Then, a long sigh of relief.

It's saved.

The rest, take your time. There's no need to be so fierce.

But as soon as he slowed down, there was a burst of Kucha Kucha next door.

It's like fighting.

Li Zheng also did not think that this thing should be like yawning, but also with mutual infection.

As soon as the next door was strong, he also followed the fierce, tumultuous.

The two of them helped each other. In just two minutes, they finished the ten minute project.

Li Zheng is also rare so unobstructed, thinking that the hero next door must be so, inevitably there are some coquettish feelings.

Unfortunately, now people live in buildings and have independent toilets. I'm afraid they can't enjoy this kind of pleasure any more.

After the lyric, he opened his schoolbag and pulled out the paper towel.

Then there was a stare.

I remember it's mostly a bag.

Why just one?

Think of the special circumstances of today's flying stars.

It's a bit difficult to handle.

No way.

Fold it a few more times.

Better than nothing.

Just as Li Zheng was checking how to use this piece of paper, a slightly immature male voice came from the next door.

"Are you..."

Li Zheng was stunned.

The hero next door?

And a young hero.

"Well?" Li Zheng immediately responded to him.

The young hero pauses for a moment, and asks in some embarrassment: "inner Brother How much paper is there... "

Li Zheng was flustered and looked into the palm of his hand. The thin tissue, which was just a little bigger than his palm, said stiffly, "I Just one... "

"Ah..." The young hero sighed, "walking, suddenly jumping You too? "

Li Zheng sympathized, sighed and replied, "yes, this kind of thing is always unprepared."

"It's like love." There was a sigh next door.

“……”

“……”

"Good Literary talent. "

"Thank you very much. Thank you very much You Wipe it, leave me alone... "

Li Zheng looked at the only piece of paper in his hand and said, "otherwise, I'll finish it quickly and go out and buy some paper for you.""Don't I'm sorry to trouble you... " The young hero only bit his teeth and clucked, "don't worry about me. I'll try my best."

Li Zheng shivered all over.

You can't do it, hero.

Think of everyone Ping shite meet, fate, Li Zheng is also a bite teeth, bite the same cluck.

"I'll tear half of it for you. We'll both save some."

"Goodbye You are not enough... " The hero declined.

"It's OK. I'm good at math. I can calculate the maximum utilization rate." Li Zheng said, turning out the ruler from the schoolbag, folding the paper towel in half and clamping the ruler, ready to cut.

"Well, I'm good at math, too." The hero next door seemed to be ignited with interest, "brother, quickly tell me the length and width of the paper, and I'll help you calculate it together."

"Oh? It's interesting. " Li Zheng thought of this, but did not rush to cut, first measured, "18x18cm, original folding method, is 3x4, 12 grid."

The hero then thought, "well If you can make full use of these 12 grids, one person will wipe six times, which is barely enough. "

"Yes, but with a 50% discount, the number of uses is halved." Li Zheng frowned and said, "but also need to consider the hand and buttocks, can not touch."

"So I seem to have seen this origami problem. " Hero's voice suddenly raised, "I remember, the satellite's solar panel, because to fold and expand, it seems that there is an algorithm, wait for me to check."

On this issue, Li Zheng is more inclined to the practical school, holding the paper in his hand and trying again and again.

After a while, the hero knocked on the partition: "if the paper length is l and the paper thickness is t, then l = π T6 times 2 to the nth power plus four, and then multiplied by 2 to the nth power minus one. This n is the maximum number of origami. We almost make a log to calculate it."

Li Zheng murmured: "wonderful is wonderful, but this seems to be a simple discussion on how many times paper can be folded? We still need to discuss the area used each time and how to keep it away from hands. "

"Yes These plans are unreliable. Has no one studied such an important mathematical problem? "

"I've got a curvilinear plan to save the country." Li Zheng swallowed his saliva and said, "your fingers go straight through the middle of the paper, and then use your fingers What do you think of it when you're done, wrap it around, scratch your fingers, and then throw them away? "

"This It's also a way, but it's a big loss. " When the hero finished, he suddenly thought of a plan, "brother, we can wipe at the edge of the place, and then fold in a small part of the wiped, change the edge, and then wipe, roll the paper in a little bit, and finally turn it into a ball."

"Wonderful After Li Zheng's praise, he suddenly came to the inspiration, "I think it can be strengthened. There is an angle α..."

"Yes, but it can be optimized. After calculating α, put the diagonal line..."

"Well, it's interesting But are we going to give our fingers at least a few square centimeters of space? "

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

Ten minutes later.

"Yes, that's it. It's time to start it!" The hero said, "so that each of us can use it seven times, but we can't touch it."

"Well, I'm going to draw the inscribed circle for the angle..." Li Zhenggang wanted to take the pen, but he felt it was not right. He knocked on the clapboard and said, "brother Since it's so troublesome, why don't I just fold this piece of paper in half horizontally and vertically twice and cut it into 16 small squares? "

"Ah The hero patted his head, "yes, throw it away with a diamond every time. Yes, brother."

"Then I'll cut it off?"

"Please." The hero sneered, "as soon as we discuss mathematics, we fall into it. Brother, we're laughing."

Li Zheng also said with a smile: "me too, you see my compasses are drawn out."

"So It seems that compasses can also be used... "

"To That's it, brother

Because it takes too long.

When the last two people used it.

It's almost done.

But this does not hinder their academic enthusiasm.

While rubbing hard, they greet each other.

The hero asked with all his might: "brother, you smell so bad."

"Oh, I had too much stinky tofu last night. I'm sorry."

"Damn it, no wonder." The hero then asked, "brother, are you big thistle? So strong. "

"I'm a sophomore in high school. I'm just passing by."

"So coincidentally, I'm also a sophomore." Hero suddenly thought of what, "this big Tuesday, you high school do not have classes?"

"Class, I have something to do here."

"So coincidentally, I have something to do..." The hero's voice began to tremble, "you're not going to From Jida Huayuan? "

"Yes." Li Zheng said in surprise, "you will not Is it competition? ""Yes The hero was completely excited. "Are you contacting Mr. simmig?"

"Yes."

"You You should not be... " The hero said impatiently, "Li Zheng

"Shit Li Zheng was shocked to beat the door, "Shi Yang..."

"Is that ok?" The hero was overjoyed. "I thought I would meet you."

"Who is not?" Li Zheng is also working hard to wipe up, "don't say, quickly wipe."

Li Zheng ran out of eight pieces of paper. He retreated from the room, brewing emotions, and slowly pushed open the single room door.

Before the door was opened, there was a sad voice from a man outside.

"Two big brothers, please, hurry up!"

Li Zheng opened the door, lowered his head and quickly flashed out.

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

The door "bang" suddenly hit, almost at the same time, there was a sound of sound.

The hero next door sighed, "you are happy enough."

"Enjoy your horse..." But the man burst out the rude, gnashing his teeth and swearing, "skin The buckle is stuck. "

This voice is not only angry, but also contains endless sorrow and humiliation.

Li Zheng didn't dare to think much about it. He quickly backpacked and washed his hands.

The hero next door rushed out with his pants in his hand and washed with Li Zheng side by side

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