Five points and nine points left, and the provincial team training sign was completed.

After teacher Xie finished smoking the last cigarette, he stepped on the door and entered the classroom. No one looked at it all the way. He walked over to the blackboard, picked up the chalk and wrote three large, slanted characters——

To solve their problems.

After writing, drop the chalk and light the blackboard.

"Look clearly. Among them, the disputes, don't write me Liu Jifen's fen."

In the sparse laughter, Xie Qi directly sat on the podium and rushed to the people in a class like chatting: "There are only seven days in total, let's not waste time. For this training, I have two here. The road is limited, time can only choose one. So I first ask, who wants to get closer to the truth of physics? Raise your hand."

This first sentence left people dumbfounded.

But there were still three or five people who responded, raising their hands high, including Qi Yingnan.

"Yes, I know." Xie Qiwen then asked, "Who wants to improve the competition results, raise your hand."

This time, seven or eight people raised their hands with little certainty, but Qi Yingnan's hand never dropped.

"I didn't raise my hand twice. Why are you here?" Xie Qi shook his head and smiled bitterly. "Xing Xing Xing, I know you have a difficult choice. Let's try again--"

"If you want to get closer to the truth of physics, I will take you to the real scientific research laboratory in the experimental training part. If you have the opportunity, you can also get started. In the theoretical part, I will give you cutting-edge knowledge.

"If you want to improve the competition results, let's do the topic. The most important thing in our school is the competition champion. It is up to them to tell you more than any teacher. I will help you one by one."

"Time and resources are limited, we can only take one of the two roads, and a few follow the majority."

"Below, if you want to get closer to the truth of physics, please raise your hand, and don't move to improve your grades."

After a brief explanation, there were only two people left, less than the first time.

A Qi Ying male, and a low-level auditor.

"Okay, I know." There was no superfluous expression on Xie Qi, he jumped off the podium and rushed to Lu Yangdao. "You organize it. At 9:30, the basic teaching laboratory gathers. I go out to carry the two championships. ."

After the order was completed, he walked out of the classroom with his pocket in hand, and he had already taken out the cigarette and entered his mouth.

Although the class can't understand the teacher, if they can really invite the experimental champion to provide tutoring, it is definitely more effective than most university teachers for the competition.

Lu Yang was very innocent. The opening speech of the training was originally a matter of the deputy dean. Now it is being pushed back and forth, and he can only let him be an ordinary student.

Alas, there is no way. For the sake of research, let's put it on your head.

Lu Yang walked to the podium and sighed, "Sorry everyone, Teacher Xie is more personal, but he is actually the first IPhO champion in China. He was only 16 years old at the time, and he didn't get full marks because he English is too bad to read the questions."

Rumble!

The whole class was surprised.

Is this thistle? Anyone who comes out at this level?

A student could not wait to ask: "Since Teacher Xie became famous so early, there must be a lot of results now?"

"This...Scientific research is hard work...and there is luck." Lu Yang embarrassed. "But please rest assured that Teacher Xie's understanding of the competition must be the best in our school. This training can be invited. He is not easy."

After Lu Yang said these words, he suddenly felt like growing up.

For the whole class, the liar doesn't even blink, do you know that I'm so mature?

Next, another student asked: "Senior, then we should see him, should we call Professor Xie?"

"This... he doesn't like the title of professor very much, let's call it a teacher, in fact, it doesn't matter what his name is, he doesn't mind." Lu Yang clapped his hands, "Okay, let me say a few things to note local……"

...

In the compound courtyard, Li Zheng sat alone on a stone bench, but did not rush to leave.

As the so-called far-off, all come, even if you only breathe the physical air, it is also very good.

Thinking about the past, not to mention Jida University, even the University of Science and Technology and the University of Science and Technology don't dare to think about it. Compared with people like Lin Yujing, they are in two worlds and they can't even see each other.

But now, he is really sitting here, and is not far from the most ambitious goal.

I don't know what it will be like when I really go to college.

During the reverie, a smell of flue-cured tobacco flew over.

Li Zheng frowned and turned his head, so that he just pinched the cigarette and sat next to Li Zheng.

"Don't think about it, it's meaningless." Xie Qi patted Li Zheng's shoulder, "I really like it, go abroad, IPhO is a good opportunity."

"?" Li Zheng subconsciously moved to the side, considering that the other party is Teacher Ji, it is not good to refute face to face.

"Li Zheng, right." Xie Qi smiled at the teaching building and said, "When you look up at it, you can only see the side exposed to you, and you will imagine that it is particularly sacred and beautiful. When will you really board? Now, you should see what it means to be dirty."

Li Zhengwenyan stood up directly: "If this is the case, why don't you go abroad, Teacher Xie?"

"My English is not good." Xie Qi nodded and nodded. "The most TM is annoying English."

"..."

"Haha, okay, you love it, don't nag anymore." Xie Qijun also got up and walked out, and suddenly turned back after seven or eight steps, "Learn mathematics, how good and how good you can learn, Not only competitions, but also important in the future."

"Um..." Li Zheng nodded skeptically.

This instruction is really concise.

...

When leaving the compound, Li Zheng was about to pass by the early stalls that he often patronized during the chemistry provincial team training, thinking that his tofu brain was quite delicious, so he wandered over to get a bowl.

Seeing that Li Zheng noodles were cooked, the stall owner filled up the tofu brain and sprinkled more coriander.

He was about to hand it to Li Zheng, who suddenly raised his hand and said, "Come again 2/3 spoonful of marinade, thank you."

"Oh?" The stall owner continued for Li Zheng more than half a spoon, and chuckled softly, "Don't you be afraid of salt?"

"Not salty." Li Zheng took the bowl confidently. "You give a lot of tofu and cilantro today. It won't taste enough without a little bit of marinade."

The stall owner only noticed that the amount of seasoning had already formed a habit, and they obviously gave them tofu, but forgot to match the corresponding marinade.

Such miscalculation should not appear in the old stall.

On the one hand, the stall owner was quite ashamed, on the other hand, he looked up to Li Zheng again and couldn't help but apologize.

Unexpectedly, this cooked young man, young, is already an old tofu brain eater.

Close to the stall, there were no guests, and the stall owner looked at the young old diners with great interest.

On Li Zheng's side, sitting with tofu brains, lit a little spicy oil, picked up a spoon, and slowly made a whole half-spicy and non-spicy area.

The stall owner looked at the spoonful of tofu and nodded convincingly.

Here, it shows the level of eating tofu brain.

On the one hand, if you want the taste to be even, you need to stir it properly.

But once stirred, it will destroy the overall feeling of tofu. The whole piece of lubricated tofu brain will become fragmented and tasteless.

For real old diners, a spoonful of it must be a whole piece of tofu, plus just the braised and spicy oil.

I really did not misread people.

After Li Zhengshu took the next spoon comfortably, he pursed his lips happily, then looked at it slightly, and steadily took the next spoon.

After eating three or five spoons in this way, the stall owner has shown a full smile.

Huh, this kid's attainments are more advanced than expected.

It should be noted that each scoop of tofu brain is particular, and the seasoning should be evenly distributed.

If only white tofu is left at the end, it will be tasteless.

If only seasonings are left, then the previous experience will not be extreme.

It's simple to say, without more than a decade of effort, Xiu Xiang really makes every spoon evenly distributed.

Unless it is said, this is a mathematical problem.

Assuming that the total amount of tofu brain is X cubic centimeters, it takes Y spoons to finish eating, and the size of each spoon is similar.

Let the total amount of seasoning be Z ml.

Then, each scoop corresponds to X/Y cubic centimeters of tofu and Z/Y milliliters of seasoning.

Plus the uncertainty of coriander and spicy oil.

To achieve perfect distribution, calculus and limits must be introduced.

But even with perfect calculations, they still face the inaccuracy of human visual inspection and the instability of human hands.

It can be said that the perfect eating of tofu brain, like European geometry, only exists in abstract theory and cannot be realized.

But this does not prevent human beings from pursuing perfection.

It is like saying that the length of 1 cm is abstract. Although it can not be achieved exactly, humans can continuously improve the accuracy and get closer to the limit of accuracy.

At this time, Li Zheng is the challenger of this limit.

Every scoop of him is so flawless in the eyes of the stall owner.

In a blink of an eye, half a bowl of tofu brain finished, the stall owner stared at the situation in the bowl.

The size of the tofu brain is reduced by half.

The thickness of the seasoning is also reduced by half.

Perfect...too perfect...

In the excitement, a round-faced girl with glasses walked to the booth and looked at the bun cage piled high on the steamer.

"Soup dumplings, the bottom drawer, thank you."

The stall owner only heard the voice and knew who it was, shook his head with a smile, and pulled out the basket of steamed buns she specified: "New steamed, rest assured, another bowl of soy milk?"

"Hah, you remember." The girl took the bun with a smile and transported it to the table behind Li Zheng.

The stall owner filled a cup of soy milk and was equally full of admiration for the girl.

If that guy is an old tofu brain, this girl is an old soup dumpling.

The knowledge of soup dumplings is no less than that of tofu.

The simplest one-be sure to eat fresh steamed.

If the buns are cooked long ago, the buns placed on the top of the insulation for a long time, the bun skin will probably be stuck with the cage drawer, and it will break when it is clamped.

For the soup dumpling, breaking it is a devastating experience, no less than the destruction brought about by the ballpoint pen answering the question card during the exam.

Therefore, the savvy old soup dumpling diners must observe the cook's cage arranging techniques in advance, lock the newest one, and cut off the meat when it is just steamed.

The girl with the round face paid the money and took the soy milk, so that on the seat behind Li Zheng, she pulled out chopsticks with a little anxiety, and sandwiched it on the edge of the bun mouth of the soup bag, shaking slightly.

The corner of the stall's mouth slightly raised.

This is not a panic, but a time to seek the limit.

As for the shaking, the first thing is to loosen the bottom of the soup dumpling sticking to the cage drawer a little, reducing the "skin breaking rate" when the bun is clamped for a while.

Secondly, the fat in the soup bag and the meat filling are mixed evenly, so that the soup is not too greasy.

Sure enough, after shaking the girl a few times, holding the Baotou firmly, the whole soup bag was picked up without leaking.

The following is the most critical step.

The round-faced girl clipped the soup bag, and did not rush to the entrance, but put it in the spoon, poked a small hole gently, and then picked up the bun, let the soup flow to a spoonful, and then sent the spoon to the mouth Side, gently blowing, and finally pursed his mouth to **** clean.

"Hoo..." The girl showed a full expression, and after tasting enough soup, she stuffed the remaining buns into the mouth.

That's it, the core of soup bag is soup, not bag.

If you chew in a mouthful, you will reverse the subject and verb and lose the essence of the soup.

However, such a "pour soup into spoon" way of eating is not the most perfect.

Is it because of that?

The stall owner looked at the round-faced girl with a suspicious look at the seventh bun.

This time, instead of putting it in the spoon, she tilted her head and held it in her mouth.

coming!

I saw the girl biting lightly, and after making a gap in the skin, she just "sucked" and sucked the delicious soup clean.

This is the most perfect way to eat.

The girl obviously knows.

I hadn’t eaten it before, just because it was too hot and I needed to pour it into the spoon and blow it.

But if you wait for it to cool naturally, there is an increased risk that the soup will stick to the bottom of the cage and break.

The seventh one starts to suck, basically the best solution.

Looking at the things in the past 100 years, there were people on the Jida campus, and the stall owner smiled comfortably and packed up the stall.

Some traditions have long been overturned.

Some inheritances are just beginning.

Seeing the stall owner closing the stall, the man and the woman also accelerated the pace of eating early, and handed over the bowl almost simultaneously.

Heroes, it was only at this time that they met.

"Li Zheng?" the round-faced girl exclaimed. "Why are you..."

"You are..." Li Zheng looked at the girl for a long time, and then said with a flinch, "Shen...Sister Shen Xue?"

"Fuck, I haven't known for so few days?" Shen Yiyun scolded his mouth and scolded, "White-eyed wolf!"

"No... I have a good memory, it's your problem."

"I?" Shen Yiyun narrowed his eyes. "Hey, let's just say it when the person is pretty~~~"

"Good...beautiful, so beautiful that I can't recognize it."

"Why are you so insincere?"

"Hahaha." The stall owner laughed. "Someone is embarrassed to say that you are getting fatter. It's nicer to be fatter."

Shen Yiyun's complexion pulled Li Zheng away.

The stall owner did not know that this sentence made him lose a **** eater forever.

Li Zheng and Shen Yiyun walked all the way to the east gate. After chatting about the current situation, he learned that the IChO finals had ended. The closing ceremony started at about 4 pm today at Jijing time and announced the ranking.

"So, do you want to watch the live broadcast together?" Shen Yiyun asked.

"Will not delay your work and study?"

"Hey, this is still the "May Day" holiday~" Shen Yiyun pulled Li Zheng with both hands, "Come on, don't you want to see Zhou Chenghuan Shi Yang they won the prize?"

"It's also... quite interesting..." Li Zheng thought about it and said, "But it's still early, we have nothing to do when we are idle. I haven't come to thistle for a long time, and I still miss some things."

"such as?"

"Run for five kilometers."

"..." Shen Yiyun retreated.

"Come on, come on." Li Zheng pulled Shen Yiyun back, "Don't give up yourself, come on, work hard, be strong."

"Isn't... one kilometer..."

"What a joke? That's not even the foreplay. Five kilometers is not so difficult. At first, it did feel like it was dying, but if you get used to it, you can be free from the edge of life and death."

"Don't...don't go back, ICHO doesn't look at anything."
