Some people go camping with their families when the cherry blossoms are in bloom.

Someone sipped tea and held hands while the fireworks exploded.

Someone was gnawing on ham while staring at the rocket launch tower.

We discussed strange things while gnawing on ham sausage.

Li Zheng and Lin Yujing sat side by side on the trunk, pointing to the several metal frames arranged on the left and right of the rocket body and discussing.

"Hey, there are a few racks inserted into the arrow body. What are they used for?"

"There seems to be white smoke coming out, maybe it's the coolant being recirculated?"

"Or injecting fuel? The fuel itself is liquid hydrogen and liquid oxygen, right? Because the temperature needs to be kept below -253C, it is more efficient to inject it before the launch is approaching?"

"I don't know this either..."

Li Zheng laughed and said, "Can you do that? That's it?"

"I can only find information from the Internet." Lin Yujing took a bite of ham bitterly, "My mother didn't tell me anything..."

"Ha, my dad never hides his swordsmanship." Li Zheng gestured, "Quickness, accuracy, and stability are the essence of my Li style of swordsmanship."

Lin Yujing froze for a moment, then sighed softly and said, "Zha Yu, you don't have to look for words like this."

Li Zheng smiled awkwardly and said, "Isn't this because I'm afraid you'll be nervous? I feel like your expression is not right."

"Mom will only be more nervous than me..." Lin Yujing turned around, put down the food, and leaned against the edge of the trunk, "It's okay, Zhaji, just wait quietly."

Li Zheng turned around and took out the game console: "Waiting is waiting, do you want to come and play the car?"

"No, you can play."

"..." Li Zheng sighed, put the game console back, and took out a math problem, "Then I'll study."

After waiting (learning) silently for more than half an hour, a broadcast suddenly came from the launch site.

Because the echo was so loud, I couldn't hear clearly what was being said. I could only assume that the launch was confirmed, the countdown started, and the on-site personnel were asked to leave.

Lin Yujing stood up.

Li Zheng also put down his math problems, turned on his phone and clicked on the live news link.

The live broadcast is divided into two screens: the left is the distant view of the launch tower, and the right is the busy scene of engineers at the launch center.

There was no news narration in the entire live broadcast, only the title subtitles [Live broadcast: Huanghe-2b is about to be launched].

This atmosphere undoubtedly added a bit of tension.

As for Lin Yujing, staring closely at the arrow body, she was speechless.

"I...I'm afraid..."

After saying this, he unconsciously leaned towards Li Zheng.

Seeing her getting closer and closer, Li Zheng hurriedly turned around and took out the game console: "Why don't you play racing soon?"

Lin Yujing's approach suddenly stopped. She turned around, grabbed her backpack and held it in her arms. She stared at the launch tower without saying a word.

Immediately afterwards, another broadcast came from the launch site, but it was still unclear.

But for the first time, a voice came out during the live broadcast——

[Attention everyone, 3 minutes to prepare!]

At this moment, Li Zheng's heart also felt "bitter".

Lin Yujing even yelled briefly and grabbed Li Zheng's arm.

"So fast..." Li Zheng swallowed and put his hand on the back of Lin Yujing's hand, "Don't be afraid, this is a great moment."

Just as he was talking, billowing white smoke suddenly appeared from the connection between the metal frames and the rocket, and then spread out to the left and right.

It's like a mother spreading her arms around her child.

"Afraid..." Lin Yujing pressed closer to Li Zheng's side.

Feeling the soft forearm, Li Zheng felt his scalp numb.

The two meridians of Ren and Du seemed to be opened instantly.

His right hand, which was originally sitting in a standard sitting position and spread on his thigh, was lifted up by mistake and passed behind Lin Yujing. After a lot of determination, he finally put it on her right shoulder timidly.

He could feel Lin Yujing trembling, but she didn't resist. Instead, she leaned closer to his shoulder.

Li Zheng naturally embraced her.

Neither of them looked at the other, nor did anyone say anything.

In their eyes, only the Yellow River No. 2 is in front of them.

I don’t know how long it took, but the voice came again from the live broadcast on the mobile phone.

【40 seconds!】

They all hugged him tighter.

【30 seconds!】

Li Zheng felt like his thigh was being pinched hard.

【20 seconds!】

The waist was also pinched!

【10!】

【9!】

【8!】

Li Zheng's own hand didn't realize it was getting tighter and tighter.

【7!】

【6!】

【5!】

Hold your breath!

【4!】

【3!】

【2!】

【1!】

【ignition!】

At the same time as the order was given, a thin red line appeared under the arrow body.

Then, the red line suddenly exploded, like a little sun emerging from the sky.

Only then did the roar come, and the two people's faces were reflected red by the flames.

In another moment, the little sun suddenly burst out with dazzling light and quickly became a big sun.

In that dazzling light, Huanghe No. 2 soared into the sky.

Amid the shaking of the ground, the four take-off propellers around the rocket spewed out four giant flames several stories high. They were like four long tails of barbaric flames, burning desperately regardless of the cost, in a barbaric way.

Way to propel the rocket into the sky.

Viewed immersively, the speed at which Huang Er ascended to the sky completely defied human intuition, like a sun suddenly thrown out by a giant, making the entire bay seem like daylight.

But precisely because of its speed, the daylight period was very short. After just a few seconds, it rose straight into the sky, like the sun rising across the sky.

At this time, the roar in his ears weakened, but a new tremor came from the ground.

This time it's humans who bring the tremors.

Li Zheng clearly heard people cheering from different viewing points nearby.

He just came back to his senses and turned to look at the person in his arms.

Lin Yujing was still staring at the rocket, her eyes filled with tears and she was trembling.

"Okay, it worked." Li Zheng nodded vigorously, "Awesome."

"Wait a little longer... wait a little longer..." Lin Yujing held Li Zheng's hand tighter, "It will be considered successful only when the star and arrow are in orbit and separated."

Before she finished speaking, the head of the rocket began to press toward the east, and the flight elevation angle gradually became smaller, from flying straight upward to flying along a tangent to the earth.

The intuitive feeling with the naked eye is that the sun is beginning to tilt.

The physical feeling is...

The thigh was pinched again.

"Don't be afraid, it's a normal ballistic adjustment." Although Li Zheng didn't understand it, he still explained it in a decent manner, "In order to reach the first cosmic speed and successfully ascend to an altitude of 36,000 kilometers, rockets are all

Such a launch trajectory."
