When I was a student, I often had this happening.

Before the summer vacation, a cowardly brother who was still not good-looking.

But when I came back from vacation, I suddenly changed my look and became a radiant confident and handsome man.

Li Zheng, who returned to the first courtyard, felt a little like this.

He had been humbly learning before, but suddenly he became a real business backbone.

In addition, a considerable part of the original Huang Er team was transferred by 927, so even interns like him and Lin Yujing will be entrusted with important tasks.

With his enthusiasm, Li Zheng became the connector who coordinated the work with the 17th Institute, and was also responsible for the data demonstration work, and had his own temporary office.

Lin Yujing joined the design team to assist Shen Tinglan in the final round of new engine optimization.

Saturated, Li Zheng just squeezed out time to participate in the information finals.

This final is amazing...... The proportion of junior high school students has increased significantly, and there are even elementary school students......

The intensity of the competition also far exceeded Li Zheng's prediction, it was not an unpopular competition at all, and it was close to mathematics.

No way, computer expertise is too popular, especially when it comes to biochemistry.

However, compared with the biology competition students, this information competition students are more unlucky, although Li Zheng is also unprepared, but he has been engaged in this work almost every day for half a year, plus the learning software has always been maintained and upgraded, expanding the testing area, after such thousands of hours of accumulation, he is already a real old programmer.

This is also the championship he is most embarrassed to win, and he feels that he is bullying other people's efforts to go to school with his ability to eat.

Especially when he saw the crying people in the audience, whose identity and figure were obviously elementary school students, but their faces were already close to those of graduate students.

Since then, the fourth son has completed Dengke, and only the mathematics final of the following year is missing.

At the beginning of the winter vacation, when the students in the class were sprinting for the college entrance examination, the mathematics training of the provincial teams was also officially launched.

Gui Jianfeng was well prepared this time, and happily carried a big schoolbag into the thistle.

When it came time to report, the teacher in charge was flattered and grateful.

"Great...... I'm afraid you won't come......" The teacher said while pointing to Gui Jianfeng's signature, "Our training team has discussed, your score of 174 points, not to mention Jijing, there should be few players at this level in the country." Haven't you already been admitted to the Department of Mathematics, and it just so happens that several professors are paying attention to you, and this time they will directly tutor you. ”

"Ah...... You don't need to ......," Gui Jianfeng glanced at the list and said, "Li Zheng has also taken more than 150 exams, and there is also special counseling, right?"

"This ...... Li Zheng is indeed very prominent, but he signed a contract with the School of Physics, as if he plans to go to Yingpei, and several famous professors on our side also have more mathematics students to take care of......"

"......" Gui Jianfeng flipped through the registration roster a few times, "Why didn't I see his name?"

"Don't mention it. The teacher shook his head and sighed, "When we first contacted the school, the school said that they had already gone to the unit for an internship...... Then gave us a phone call...... As a result, the human resources department of the aerospace group said that Li Zheng was tackling key projects, and the organization and he personally thought that it was not appropriate to participate in the training camp at this time...... You said that we are a provincial team engaged in training, where have you seen this......"

"!!" Gui Feng patted his eyes at the pen, "But he just went to the information competition and won the championship! The competition in the past two years is about to win a grand slam." ”

"??? "the teacher is in place" for a long time, "Is there really such a person?"

"Anyway...... He's not coming to the training camp......" Gui Jianfeng asked.

"It's definitely not coming......

"Alas......" Gui Jianfeng sighed, and then laughed again, "Okay, it's ...... flat"

After that, he bowed to the teacher and said, "Something suddenly happened at home...... We'll see you in the finals too. ”

Faced with this decision, the teacher did not show the expected surprise and embarrassment.

"Absolutely, hey. The teacher shook his head dumbly and said, "This really made him count ......."

"What?"

"Wait a minute...... the teacher picked up his phone, "Teacher Xie...... As you might expect...... Come on. ”

As soon as he finished speaking, the door to the stairwell opened.

Between the smoke, the squinting eyes appeared.

As soon as I saw the long hair style of Guijianfeng, I was excited: "I can catch you." ”

Gui Feng took a step back: "You are ......"

"Li Zheng has recommended it to me many times. Xie Qifeng rubbed his hands and pressed over step by step, "I've been hungry for you for more than half a year." ”

"Teacher Xie, don't ......be like this," the teacher in charge hurriedly stepped forward, "It's a math academy here, converge a little, converge a little." ”

"Hey, math and physics are not separated. Xie Qifen stretched his neck and said, "Li Zheng asked me to talk to you, and I have to listen to two classes before I can settle it." ”

"......" Gui Jianfeng smiled helplessly, "Alas...... A ...... that should have been thought of a long time ago"

At the same time, the first improved YF-87 test machine was assembled in front of the launch pad at the test site in the western suburbs.

Zhao Zhenhua, Chen Hongbing, Shen Tinglan, Zhu Mingyue and other responsible persons were all present.

Li Zheng and others were also in place in front of the screen in the back row.

The future of the hydrogen-oxygen engine route is only in today's results.

With Zhao Zhenhua's order, the first test run officially began.

In the picture, the main body of the engine is fixed to a test launch pad, enclosed by a rectangular structure.

In the roar, flames and smoke erupted from the bottom of the platform.

Unlike before, this time it is no longer a test run in a steady state, but directly in the harshest environment, which previously led to shaft breakage.

Now, that ordinary steady-state test run is no longer meaningful.

Live or die, there is no longer a middle ground, and there is no room for maneuver.

No one wants to waste a second of their time anymore.

Life or death.

Come on, come soon.

In the entire central computer room, all the leaders are always standing, staring at the monitoring screen and not even daring to blink their eyes.

The technician didn't look at the screen at all, and only focused on the data graph of the small screen in front of him, some of which were numbers, some of which were graphs, and whatever it was was a matter of life and death.

No one spoke, and only the vibrating noise from the experiment echoed in the room.

10 seconds.

20 seconds.

50 seconds.

100 seconds ......

Li Zheng had never felt that time was so slow.

When he thought it was almost time to finish, there were only 120 seconds on the display.

At some point, a hand grabbed his palm.

He could feel the cold palm, covered in sweat.

Lin Yujing looked at the screen in front of him tremblingly, and he didn't dare to breathe, only dared to catch Li Zheng.

Li Zheng coughed: "What's the panic...... Atmospheric point. ”

"I didn't panic...... Lin Yujing twisted his face and bowed his head, "but your legs have already shaken to me......"

"Ah......" Li Zheng looked down and saw that his legs were shaking uncontrollably.

He quickly pressed his leg to death.

"I haven't been exercising much lately, and I'm ...... calcium deficient"

"Don't talk about it...... Lin Yujing grabbed Li Zheng's hand and rushed forward with a pout, "Look at Zhao Zhenhua...... He's shaking ...... too."

Li Zheng looked up and saw that it was really so.

Not only Zhao Zhenhua, but Chen Hongbing also wiped his hands on his pants repeatedly, as if he couldn't wipe them dry.

The breakage accident occurred in 57 seconds before the previous test was completed, and these improvements have proven to be effective from this point of view.

But it's not enough...... 1！

In fact, even if you don't change it and launch it again, it will be difficult to encounter the same harsh environment again, and the success rate is more than 90%.

But it's not enough......

To prove the viability of this route.

To prove that it was all worth it.

It had to be carried for 300 seconds.

150......

180......

210......

The engine has long since reached its limit, like everyone here.

But it's not enough......

I want to overtake in corners, I want to rise in aerospace......

That's not enough......

240......

270......

Looking at the increasingly violent curve fluctuations, Li Zheng seemed to have heard the moaning of the engine.

Just like the unremitting struggle, burning life holds up all this nation of everyone.

But it's not enough......

You can vent, you can scream......

But please, hold on......

It's just a little bit, it's almost the last point......

298......

299......

300！！！

When the timer arrived, the engine went into a cooling shutdown phase as planned.

At the same time, Zhao Zhenhua turned his head almost with red eyes: "How is it?"

"Everything works fine. ”

"Normal. ”

"Normal. ”

After Li Zheng looked at the whole curve chart in a suffocating moment, he finally raised his head.

"Normal. ”

Zhao Zhenhua's body shook, covering his forehead, almost collapsing.

"First...... Don't jump to conclusions...... Cool down as soon as possible...... Dismantling and checking ...... The data set also starts checking ...... immediately"

He finally walked out with the support of Chen Hongbing.

At this moment, no one is happy.

Everyone is still looking at it, checking again and again.

The maintenance team has already been dispatched, and the staff of the relevant factories boarded the special rack truck to prepare for the on-site unloading and dismantling.

They are like blind long-distance runners who dare not stop even if they cross the finish line until they hear the cheers.

Half an hour later, Li Zheng gave the fastest analysis results, not because of his personal efficiency, but because he and the Harbin Institute of Technology team had already honed the software and algorithms.

After an hour, the groups completed the verification one after another.

Two hours later, Liu Rui, with the assistance of everyone, completed the preliminary manual verification.

Everything points to one result, but no one dares to say it.

The luncheon, the afternoon presentations, and arguments were all done in a depressing atmosphere.

Until sunset, everyone came to the test site.

Watch the mechanic disassemble and watch the driver detach.

At this point, the engine has cooled down and the plant technician is disassembling the components, starting with a full inspection of the oxygen turbine pump.

It's been another long wait.

The first courtyard, together with the fifty-seven people of the seventeen houses, all stood motionless in the cold wind.

I don't know how long it took, when it was so dark that I could barely see anything.

The master technician suddenly raised his hand, and the thick gloves made a bloated gesture.

"No cracks found, everything is !!"

Suddenly, a landslide and tsunami occurred.

People who held it for hours, months, and years, regardless of their identity, age or gender, let out a roar at any cost.

"Ah!!!!h

"Fuck !!"

"Awesome !!!"

This was followed by a torrent of tears.

Hug and cry with the people around you.

suddenly talked about his deceased mother, and he couldn't be with her in the last days.

I couldn't help but talk about the newborn child, and I only looked at it once.

Behind this, there are also wives who are struggling to support the family.

It is necessary to force the elderly to make their own buses to go to the hospital for treatment.

They don't know how many parent-teacher conferences they've missed.

I have long forgotten the last time I saw a waking child.

The cage that restrained memories and feelings seemed to be shattered in an instant.

The redundant regrets scattered like bomb fragments.

After being silent for too long, everyone was like a Tang monk, crying and confiding in these unspeakable things in the past.

That majestic meaning dissolves at this moment, turning into a parent's shortcoming.

Even Zhao Zhenhua cried this time, squatting on the ground and crying for a long time, crying and scolding.

"It can't be like this, comrades...... Haven't won yet......"

Li Zheng was in the middle of it, and he knew that compared with anyone here, his efforts were just a drop in the ocean.

Turning to look at the side, Lin Yujing wiped her tears, choked up, and her face was already blown red by the cold wind.

She kept holding his hand, and she didn't let go of it at the moment.

"Don't cry, your face is ......," Li Zheng wiped his eyes, "Besides, you didn't do anything...... I get off work every day. ”

Lin Yujing stomped over and said stupidly: "I just didn't expect it...... So tired...... It's so hard ......."

"But we didn't do it anyway. Li Zheng turned around and helped Lin Yujing re-wrap the white scarf and cover his face, "I know you're here...... It's quite uncomfortable, but this is the life of an engineer, a life without any shortcuts, and it is also the life that Aunt Shen has been experiencing. ”

Lin Yujing stretched out her scarf, revealing only a pair of eyes: "Anyway...... This...... This time......"

She said, turning her head unwillingly: "Count you on this time......"

"!!" Li Zheng's eyes widened, he took out his mobile phone and started to take pictures, "Quick, say it again!"

"Get up, get up!" Lin Yujing pushed Li Zheng and scolded, "What do you want me to do, the project is all hard work, and there is no room for brains at all, how can people compare with Rubi!"

"None of this matters, come, who's up there?"

"Not yet, it's not really on it until it is successfully launched. ”

"Heh, I like the way you look at your hard mouth. ”

As he was talking, Zhao Zhenhua and Chen Hongbing walked over like a pair of elderly brothers.

Behind him are Shen Tinglan, Zhu Mingyue and the leader of the first cadre.

"Alright, go back and warm up. Chen Hongbing waved his arms and said, "There is still one last step left, don't rush to get married first." Hold on, Secretary Zhao said that Huang Ercheng will only give you a marriage certificate after Huang Ercheng becomes it. ”

Lin Yujing "slipped away" for a while, and disappeared!

However, Shen Tinglan was already very adapted, and only mentioned the zipper of Li Zheng's down jacket: "Don't catch a cold, you are now using 5 people by one person...... When Huang Er is officially launched, I will invite your parents to a meal, thank you well, and tell them what you have done. ”

"Oops, hey, hey!!" Chen Hongbing went up and gave Li Zheng his head for a moment, "What's the matter with you, your parents still let your mother's family mention it when they meet?"

“......”

Zhao Zhenhua also smiled and nodded: "Don't say anything else, at least the Shen family has already recognized you." ”

Shen Tinglan didn't refute or cover his face, but just patted Li Zheng with a smile, and then went to chase Lin Yujing.

Chen Hongbing directly hooked Li Zheng and hugged him to the office building: "I am familiar with this process, you are like this...... Go home and talk to your parents and ask your parents to offer to meet. And then what...... Look, your Aunt Shen is alone...... It's inevitable to be embarrassed to face your parents like this, right? If you are an uncle, you have to find a way to resolve it, and if you think about it, isn't the topic of the meeting to report on your outstanding work in the aerospace system? This can be completely by the way to invite a leader to come forward, you look at me, you can count yourself as half a father...... You just invite me to go too, let me be your Aunt Shen's companion, so that the embarrassment will be dissolved, and this is called being able to do things. ”

“......”

"But don't ask Aunt Shen's opinion, you just invite me, I'll make sure you have a face." ”

Li Zheng felt that this person was not pure.

He's taking advantage of a lot of people in one go.
