When a person has a certain amount of goods in his stomach, he does not need to prepare for class.

This is also Li Zheng's second time since Zhou Chenghuan reconciled his dispute, and once again experienced a professor-level lecturer's course.

However, Du Songtao is more pragmatic than Zhou Chenghuan, more rude than solving his disputes, almost digesting and condensing Stanford's courses, and then spit out like a spore eruption.

His knowledge structure is basically free of dead ends, and he can always point out problems and quickly guide each group to find solutions.

If Li Zheng's class is to demonstrate a full set of martial arts moves at a glance, then Jun Songtao is to use the shortest time to deliver customized essence killer moves for everyone.

According to Du Songtao's words, such a training course can only be done quickly, and there is no time to engage in any knowledge structure, which has to rely on the natural accumulation of follow-up work, and Li Zheng made a directional mistake.

This night, teaching assistant Li Zheng finally realized what the gap in academic ability is.

However, what is surprising is that the system has never displayed Jun Songtao's student movement, and the same is true when facing Shen Tinglan, I wonder if the engineer will hide deeper.

In the end, Li Zheng had to accompany two more meals of wine in exchange for the last lesson for Du Songtao the next day.

......

The day before the camp ended, at half past eleven in the evening, everyone in the study group gathered in front of Li Zheng's computer.

Under Juniper's swift whip, the simulation project was barely launched, and at this time, the data had been entered, and the simulation launch would start on the remote server with just a click of the mouse.

The screen is a series of complex data-only interfaces, and there are no rocket graphics, but this does not affect everyone's enthusiasm in the slightest.

"Are you ready?" Li Zheng scanned the screen and said, "The weather environment immediately simulates the Wenhai launch site, and the target is in synchronous orbit." ”

"Hurry up. Yin Hang urged, "Launch!"

With Li Zheng's tapping, various data have improved rapidly.

However, 17 seconds after launch, the data suddenly zeroed out like dominoes.

"Blown up. Du Songtao sat on the table behind him and smiled, "It's good that you didn't blow up the launch pad." ”

"This ...... Is this the end?" exasperated the bearded, "there has to be an explanation, right?"

Li Zheng clicked the mouse and said: "The fuel chamber leaked, and the liquid hydrogen and oxygen were accidentally contacted outside the combustion chamber. ”

"What is the reason?" asked the team leader in charge of this part, gritting his teeth.

"There are so many reasons for this. Du Songtao waved his hand and smiled, "You go back and find the information to learn by yourself, and hurry up for the second launch." ”

On the second launch, the core-first stage rocket separated ahead of schedule and failed again.

The third time, the tragic explosion of the launch pad finally occurred.

It feels like watching "A Thousand Ways to Die with a Rocket".

Until the seventh time, when the data of the core first-stage rocket was abnormal, Li Zheng chose to separate in advance, and everyone had no hope, but the fuel behind actually sent the Eagle No. 1 to the synchronous orbit.

After more than half an hour of silence in the classroom, cheers finally rang out.

"Ah!!h

"It's hard to ...... It's so hard......"

"Now I finally understand the zeroing, there are too many problem links, and I really need to reset to zero......"

"Thank you two teachers, I've really improved a lot in the past few days!"

"In the future, I will never scold those regulations for being perverted. ”

Although it was almost one o'clock in the morning, the students still pulled the two to take a group photo together and hugged each other.

Li Zheng naturally added a lot of WeChat and developed eyeliner to all corners, which is probably the instinct of the demon lord.

But in fact, Du Songtao also did this, and there were more people than Li Zheng, so he was becoming more and more like a spy.

When the students dispersed and Li Zheng packed up his things, Du Songtao clicked on his laptop and said: "I see that you have secretly changed the parameters, there is no cloud, there is no gust of wind, I can't wait to take off in a vacuum, you are too used to them for this difficulty." ”

"There's always some hope. Li Zheng put away the computer and said with a smile, "If you destroy six of them, they are about to scare them out of illness." ”

"This kind of fright is magical enough, after all, in reality, you can destroy two at most, this is not burning hydrogen and oxygen, it is banknotes. Du Songtao patted Li Zheng and said, "It's time to drink, don't run." ”

"I really have to run today...... Li Zheng said embarrassedly, "There is a math competition tomorrow morning, and I won't participate in the closing ceremony." ”

"......" Jun Songtao was stunned, "That is, this is the last time we will meet?"

"Hey, there's always going to be you. Li Zheng also patted Jun Songtao, "Thank you for this time, I will definitely make up for the wine I owe you." ”

Watching Li Zheng walk out step by step, Du Songtao thought for a while and then raised his head and said, "What about other than wine?"

"For example?" Li Zheng stopped and turned around.

"I haven't thought about it yet...... Jun Songtao grinned, "remember, you owe me two favors, and you have to be on call in the future." ”

"One!"

"One and a half. ”

"One and a quarter!"

"Forget it...... Let's just one of them. ”

Jun Songtao went all the way to the door of the hall and finally sighed.

"927 has been approved, tentatively compiled into the Yellow River sequence, the technical foundation is solid, the preliminary preparation is sufficient, according to their planning, how can it be assembled from the factory by this time next year. Jun Songtao looked up at the sky, "It's much faster than I imagined, although I didn't mention it explicitly, but I always feel that this part should be left to private aerospace to do ......."

"Why are you still bothering about this?" Li Zheng snorted and laughed, "Don't hurry up and get away yet." ”

"I can't always be free, I'm all a wave and a fight. Jun Songtao chirped and said to himself, "It's amazing, being with you will stimulate my positive energy, and being with those colleagues in the unit will only make me resist this part......"

"Near Zhu Zhechi. Li Zheng was actually muttering in his heart that he was close to the ink and learned.

"Do you think I'm hungry for your body?" said Du Songtao and grabbed Li Zheng's buttocks.

“？？？”

"Just kidding. Jun Songtao pushed Li Zheng hard, waved his hand and turned around, "See you later." ”

"See you later. Li Zheng also shook his head and smiled, trotted to the door and got into the car.

After the car starts, he examines its system interface.

"Whew......" Li Zheng breathed a long sigh of relief.

It's finally done, and it's worth it to owe this favor.

I have to say that at this time, the demonization level is raised to level 50, which is simply a relief in the snow.

If the daily study time is 8 hours under normal conditions, then Li Zheng now has 19.5 times the study time, and considering factors such as relaxation and recovery, it has almost reached the level of "Zheng learns for a day and studies quietly for a month".

So next......

"3000...... Li Zheng said in a trance, "It's been a ...... day."

Hearing this, the express driver suddenly turned his head: "3000? Do you also speculate in stocks? It has indeed been a long time......

"Ah...... Just amateurs. As soon as Li Zheng raised his head, Xuelunyan couldn't control it.

【？？？】

[Academic Ability: 179]

"What!" Li Zheng was shocked.

This is much higher than Yin Hangdu, an ordinary express driver has this academic ability?

Is the driver hiding too deeply, or is Yin Hang too watery?

"What's wrong, the wrong way?" the driver was a little flustered.

"It's not ......" Li Zheng swallowed and foamed, "I feel like you...... It looks like a very high degree of education. ”

"Can you see that?" the driver looked back in surprise, "I did graduate ...... graduate school."

Li Zheng breathed a sigh of relief: "I understand, it's okay to take on a part-time job at night, it's still quite emotional." ”

"I'm full-time. The driver clicked on the steering wheel, "It's been two years of full-time driving." ”

“......”

"There's no way, why did I have brain cramps back then...... "The old and steady driver suddenly started spraying, "The 21st century is the century of biology?......!"

Along the way, Li Zheng has learned a lot, and it can be regarded as a reserve for the biological rematch......

......

The next day, Li Zhengke was happy.

It's really a joy to learn from people.

Lao Li's academic strength is 2975, which can be said to be a very terrifying existence.

As for Ning'er, although her status is very high in every sense, her academic ability has not yet reached 300, which shows that academic ability does not include things like management experience, but only about the level of knowledge in a certain field.

Strong people like Li Yi, Shen Tinglan, and Du Songtao with 3,000-level academic ability are about the level of top experts in the industry.

Between 100 and 200, it is the master's graduation level.

In the meantime, there is still a lot of space to be filled, and of course Xuelunyan cannot be stopped.

For example, office workers in the subway, most of the math power fluctuates around 100, and occasionally a close to 300 will pop up, Li Zheng will inevitably cast a respectful gaze.

It made people very embarrassed.

As for the occasional encounter of more than 300, or even nearly a thousand, Li Zheng has to stop and admire.

It was like this all the way, until he entered the preliminary competition of the Supplementary Mathematics Competition of the Normal University, and this number finally entered the stable stage.

The academic ability of the preliminary contestants is mostly within 100, and occasionally in the early 100s, but they will not be too far ahead.

As for invigilating and organizing teachers......

In fact, it is not much higher than the participating students.

After watching it like this for a long time, Li Zheng will inevitably be a little numb.

Just as he was about to put away his Xuelun Eyes, a number suddenly appeared in the crowd walking towards the teaching building.

[Academic Ability:692]

"!!" Li Zheng pounced towards the number, and soon ran behind him, tailing tightly.

It's a guy with a bit of long hair, wearing a baggy blue shirt and school uniform pants underneath.

I didn't expect there to be such a strong person among the students.

This is probably second only to his own existence among his peers.

Heroes cherish heroes, Li Zheng is more and more close, and the tighter he presses.

Finally, the man was a little overwhelmed, stopped suddenly, and turned back with some fear.

Unexpectedly, he didn't wear glasses, and his skin was fine and tender, white and clean, and he looked like he was only in his first year of high school......

Wait a minute......

"Ah......" Li Zheng's mouth drooped, "Return to the wind?"

"Ah......" Seeing the wind was first happy, and then a little embarrassed, "What a coincidence......"

Li Zheng originally wanted to go up and get close.

But I was tricked during the competition, and now I still paste it like this, isn't it very shameless.

He shook his head and walked to the other side: "I still won't bother you." ”

"Don't, don't......" Gui Jianfeng chased after him with a smile, "There is something to do temporarily, and I can't go." ”

"Then why don't you talk about it?" Li Zheng walked by himself with a straight face.

"I don't have a mobile phone...... Gui Jianfeng grabbed Li Zheng's arm and said with a hippie smile, "I promise not to escape this time." ”

"Speaking of escaping from the battle...... Li Zheng suddenly became embarrassed, "I'm actually a deserter...... too"

"Well, what's the matter? You didn't go to the physics camp?"

"Hmmm......"

"Hahaha. Seeing the wind pulling Li Zheng back, he walked all the way upstairs, "Where is Lin Yujing?"

She didn't go either. ”

"Why is this all neat......" Gui Jianfeng said with a smile covering his mouth, "Are you going to get married?"

"Go, go, go. Li Zheng threw him away at the speed of light, and then asked, "I remember that you didn't enter the national team in junior high school, what are you here for?"

"At that time, there was something to do, and I didn't go to IMO, which is a bit of a pity, and it was intermittent in the middle, and the state has not been very good. Gui Jianfeng nodded and cheered himself up, "Now is the last chance, I have to go once if I say anything." ”

"You've got a lot to do......"

"What about you two, why didn't you go to IPHO?"

"It's a long story...... Don't tell anyone else......" Li Zheng leaned over and whispered, "We've been building rockets recently." ”

"Hah...... Ha...... Ha ......" Gui Qi said with a dry smile, "There is no shortage of ballistic designers...... I can help......"

"Those jobs have already been done, the difficulty is the engine ......" Li Zheng said and quickly covered his mouth, "No...... Confidential, I can't say any more. ”

"Okay......" Gui Jianfeng cooperated with Li Zheng like a second fool, "You have to keep the secret......

"You don't understand, there's a lot going on, I have to hurry over after the exam......" Li Zheng took out the admission ticket and said, "I'm in the 17th exam room, what about you?"

"1 examination room. Seeing the wind, he also shook his admission ticket.

"It's a pity. ”

"Why don't you ......," Gui Jianfeng scratched his head and said uncertainly, "After the test, it's like a physics competition." ”

"Okay. Li Zheng nodded vigorously and said, "The Dragon Ball Group is the first answer, and I can be regarded as having successfully completed the task of this group leader." ”

"That'...... Don't call so many people this time, just the two of us. ”

"Done. ”

Seeing the wind at home, Li Zheng rarely has a trace of competition passion.

During this time, the progress of mathematics was too rapid, and it happened to be a fight with Xiaogui.

But the moment he got the volume, Li Zheng had to admit it......

The math contest is still difficult.

Although it is only a preliminary round, it is already close to the strength of the semi-final of the physics competition.

The key is that it is difficult to find any skills, and the question type is not fixed, so it is basically difficult to get a high score by frantically brushing the questions, which is a real investigation idea.

Even if Li Zheng worked hard, it took nearly two hours to complete the whole answer.

When handing in the papers, the teacher reminded with concern: "Classmates, there is only one provincial competition this year, this is the semi-final, don't you check it again?"

"Oh, I thought it was a preliminary round ......," Li Zheng sighed, "No wonder it's so difficult......

The "......" teacher looked at the paper, and his mood was inevitably a little conflicted.

He obviously finished answering more than half an hour early...... But he shouted again......

It's beeping, right? It must be beeping, right?

"It's too difficult, this year, I don't have the confidence to get a full score......" Li Zheng finally handed in the paper.

"Alright, alright...... Let's go......" The teacher almost kicked Li Zheng out in the end.

It's too much, and all the beeps have been installed on the teacher's head this year!

A few minutes later, Li Zheng caught Gui Jianfeng standing stupidly in front of the school gate.

"Damn, it's still faster than me......" Li Zheng sighed and said, "How long have you been out?"

"It didn't take long. Gui Jian Feng smiled and handed over a ball of paper, "My process has been written on it." ”

"Why ......" Li Zheng's eyes froze, and finally realized the feeling of frustration again, "You are at least faster than me...... 20 minutes?"

"About 24 minutes. Guijianfeng rubbed Li Zheng's shoulder and said, "Don't be discouraged...... If you only talk about mathematics...... You're already the fastest I've ever seen, and you see, no one from our school has come out. ”

"I ...... I...... I'm trying to learn math every day. ”

"Me too, don't be sad...... Walk around...... Go get something ......."

"There is also a teacher from Jida University who has tutored me in the middle......"

"Speak slowly, don't cry, don't cry......"

"Why am I so uncompetitive......"

Guijianfeng comforted Li Zheng all the way, and finally walked into McDonola.

After that, it took Li Zheng another half an hour to recover the answer.

There is no way to use it for so long, the math semi-final is full of proof questions, four major questions of 180 points, the difficulty is almost all in the way of thinking, the so-called right answer is actually to look at each other's proof process, both sides are convinced to be correct.

When he and Guijianfeng exchanged views on the proof process, Li Zheng was undoubtedly washed away by the pasty face of another genius other than Lin Yujing.

If Lin Yujing's talent lies in finding the optimal path, then the characteristic of Guijian Feng is the path of originality and confusion.

Especially in the use of tools such as mathematical induction and imaginary numbers, there is nothing that cannot be imagined.

Under the washing of logical words such as "counter-evidence", "obvious" and "then knowable", Li Zheng felt that his figure was becoming smaller and smaller.

When Li Zheng put down the scroll, he was completely convinced: "No wonder...... In such a short period of time...... What kind of wild way are you...... The logic transforms like a dog......"

"You're strong too. Gui Jianfeng looked at Li Zheng's roll and said very hard, "It's very ...... Very...... Very serious, very simple, very perseverance proof ......"

"You scold me!"

"No, no, no, no......" Gui Jianfeng carefully comforted Li Zheng, "But there are two places in the middle that prove that the logic is not valid, so I don't think about it a little bit...... I think I can score more than 150 points......"

"I'm leaving, I'll never play with you again!" Li Zheng wiped his eyes and grabbed the roll, "You are more unreasonable than Lin Yujing!"

"Alright, I'll treat you to McWhirlwind. ”

“...... Gaoreo's Wheat Whirlwind!"

"Plus!"
