When I was a student, this happened often.

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

But after returning from vacation, he suddenly changed his look and became a radiant, confident and handsome man.

Li Zheng, who returned to the First Hospital, felt quite a bit like this.

He who had been a humble student before suddenly became a real business backbone.

In addition, a considerable part of the original Huang Er team was transferred from 927, which resulted in even interns like him and Lin Yujing being entrusted with important tasks.

With his lingering enthusiasm, Li Zheng became the coordinator for coordinating work with the 17th Institute. He was also responsible for the data verification work and had his own temporary office.

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

Despite being saturated, Li Zheng 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 almost as close to mathematics.

No way, computer skills are so popular, especially when paired with biochemistry.

However, compared to the biology contestants, the information contestants this year are more unlucky. Although Li Zheng was also unprepared, he has been working on this aspect almost every day for the past six months. In addition, the learning software has been maintained and upgraded to expand the test area. , after thousands of hours of accumulation, he is already a genuine old programmer.

This is also the championship he is most embarrassed to win. It feels like he is using his ability to earn a living to bully others' efforts to get into higher education.

Especially when he saw the child in the audience crying, whose identity and figure were clearly that of a primary school student, but whose expression was already that of a graduate student.

Since then, the four children have completed their entrance exams, leaving only Chun'er's mathematics finals to start the following year.

At the beginning of the winter vacation, when the class was preparing for the college entrance examination, the mathematics training for each provincial team also officially started.

Gui Jianfeng was well prepared this time and happily carried his big schoolbag into Ji University.

When I checked in, the teacher in charge was flattered and burst into tears of gratitude.

"That's great...I'm afraid you won't come..." the teacher said while pointing Gui Jianfeng to sign, "Our training team has discussed it, your score of 174 points, let alone Jijing, there are probably not many in the country. A player of this level. Haven't you already been admitted to the Department of Mathematics? There happen to be a few professors who are paying close attention to you, and this time they will provide you with direct tutoring."

"Ah... no need..." Gui Jianfeng glanced at the list and said, "Li Zheng also passed more than 150, and he also has special tutoring, right?"

"Well...Li Zheng is indeed outstanding, but he signed with the School of Physics. It seems that he plans to go to Yingpei. Several famous professors here also have more mathematics majors to take care of..."

"..." Gui Jianfeng flipped through the registration list and asked, "Why didn't I see his name?"

"Forget it." The teacher shook his head and sighed, "When we first contacted the school, the school said that they had gone to the unit for internship... Then they gave us a phone call... It turned out that it was the human resources department of the Aerospace Group. They said that Li Zheng was working on a core problem. The project, the organization and he personally believe that it is not appropriate to participate in training at this time... You said that we are just a provincial team doing training. Where have you seen this..."

"!!!" Gui Jianfeng Paibi glared, "But he just won the championship in the information competition! He is about to win a grand slam in the competition in the past two years."

"???" The teacher said "?" for a long time, "Is there really such a person? The championship is determined in rounds?"

"Anyway...he won't come to training, right..." Gui Jianfeng asked.

"I'm definitely not coming..."

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

After saying this, he bowed to the teacher and said, "Something happened at home... Let's meet in the finals too."

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

"Absolutely." The teacher shook his head blankly and said, "He really figured it out..."

"What?"

"Wait a moment..." The teacher then picked up the phone, "Teacher Xie... as you expected... come here."

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

In the midst of the smoke, Jie Qi appeared with narrowed eyes.

As soon as he saw Gui Jianfeng's long hair style, he became excited: "I've caught you."

Gui Jianfeng took a step back in shock: "You are..."

"Li Zheng has recommended you to me many times." Xie Qifen rubbed his hands and pressed forward step by step, "I've been craving you for more than half a year."

"Teacher Xie, don't be like this..." The teacher in charge hurriedly stepped forward, "This is the School of Mathematics after all, so be more restrained, be more restrained."

"Hey, there is no separation between mathematics and science." Jie Qifen stretched out his neck and said, "Li Zheng asked me to tell you that you have to listen to two of my classes before we can even out."

"..." Gui Jianfeng smiled helplessly, "Oh... I should have thought of it a long time ago..."

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

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

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

The future of the hydrogen-oxygen engine route only has the results today.

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

In the picture, the main body of the engine is fixed on a test launch pad and covered by a rectangular parallelepiped structure.

Amidst the roar, flames and thick smoke burst out from the bottom of the platform.

The difference from before is that this time it is no longer a test run in a stable state, but directly into the worst environment, the environment that caused the shaft system to break before.

Now, that kind of ordinary steady-state test has lost its meaning.

Either life or death, there is no middle option, and there is no room for maneuver.

No one wants to waste another second of their time.

Be it life or death.

Come quickly.

In the entire central computer room, all the leaders were always standing, staring at the monitor screen without even daring to blink.

The technicians did not look at the screen at all, and only focused on the data graphs on the small screen in front of them. Some were numbers, some were graphics, and no matter what they were, it was a matter of life and death.

No one spoke, only the vibration noise caused by the experiment echoed in the room.

10 seconds.

20 seconds.

50 seconds.

100 seconds…

Li Zheng has never felt that time is so slow.

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

At some point, a hand grabbed his palm.

He could feel the cold palms full of sweat.

Lin Yujing looked at the screen in front of her tremblingly, not daring to breathe, only daring to grab Li Zheng.

Li Zheng coughed: "Why are you panicking...be more generous."

"I wasn't panicking at first..." Lin Yujing twisted her face and lowered her head and said, "But your legs are already shaking to my point..."

"Ah..." Li Zheng lowered his head and saw that his legs were shaking uncontrollably.

He quickly pressed his leg to death.

"I haven't exercised much recently and I'm lacking in calcium..."

"Stop talking..." Lin Yujing grabbed Li Zheng's hand and pressed forward, "Look at Zhao Zhenhua...he is shaking too..."

Li Zheng looked up and saw that it was indeed the case.

Not only Zhao Zhenhua, but Chen Hongbing also wiped his hands on his pants repeatedly, seemingly unable to dry them.

The breakage accident in the previous test run occurred at 57 seconds. From this perspective, these improvements have proven their effect.

But it’s not enough… 1!

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

But it’s not enough…

In order to prove the feasibility of this route.

To prove it's all worth it.

It must last for 300 seconds.

150…

180…

210…

The engine has already reached its limit, just like everyone here.

But it’s not enough…

Want to overtake in corners, want to rise in space...
To be continued...
