After thinking for a moment, Yang Xiaotao gave the answer, "But I have to find a reason. Let the Seventh Machinery Department cooperate with the machinery factory to develop high-precision machine tools, so that no one else can say it."

Ran's father listened and then nodded, "Okay, that's a good reason."

He had mentioned the research on machine tools to Yang Xiaotao very early on, and the machine factory was also doing it.

With this reason, it is also convenient for Yang Xiaotao to operate.

Of course, since we need to cooperate, we need to give others.

"Okay, I'll tell him."

Yang Xiaotao nodded, and the two of them didn't say anything more. Instead, they discussed what was about to happen.

"Dad, how far can this missile fly?"

"Are you talking about this time?"

"Um!"

"The theoretical data is that it can fly 1,300 kilometers. But the aluminum alloy you made last time, we redesigned it and it can fly 1,500 kilometers."

"Of course, if we rely on the rotation of the earth, this distance will increase!"

After Ran's father finished speaking, Yang Xiaotao nodded, calculating the distance in his mind, and whispered, "This distance can reach my childhood, right?"

"What did you say?"

"No, just talk about it."

Yang Xiaotao looked back at the sky, "When we go back, we will try to build a bigger one!"

Father Ran nodded after hearing this.

"In the future, there will be!"

The two said nothing more and looked at their watches from time to time.

While we were talking, someone else came to the observation point by car.

Yang Xiaotao looked from a distance and saw Mr. Wang and Mr. Qian stepping forward to greet them. They should be superior leaders.

Then everyone came to the observation point and waited with the people present.

Twelve fifty-five.

The underground control room of the launch base.

The seven people who stayed behind completed the final inspection, reported to the headquarters, and then waited for news.

At this time, in Forty-Nine City, an old man was sitting by the phone, waiting for news.

Ring ring ring

The old man quickly picked up the phone and immediately heard the voice on the other end of the phone.

"Wei Yaowu, Dai Hong, passed the physical examination."

"It's time to go!"

The old man listened for a while and then his face became solemn.

Standing up from his seat, the microphone in his hand seemed to be very heavy, and his voice became serious.

"It's time to go!"

"yes!"

After hanging up the phone, the old man sat back on the chair again.

His fingers were tapping on the table.

The next second, the old man touched his pocket, but found nothing.

"Xiao Tang!"

The door opened and Secretary Tang came in!

"Chief!"

"Here comes the cigarette!"

Secretary Tang hesitated for a moment, but still went out. After a while, he took a pack of cigarettes and delivered them to the old man.

The old man took out one, lit it, and asked Secretary Tang to leave.

A man, holding a cigarette, continued to wait in the room.

At the same time, go down to the launch base.

The seven people gathered together, and the leader hung up the phone with a smile on his face.

"Comrades! Your suicide note has been written!"

"Lao Gao, everything is ready!"

Someone beside him spoke, and the others nodded.

"good!"

Lao Gao glanced at his watch and said, "Lao Wang, Xiao Tong, get ready!"

Lao Wang, who was holding a pocket watch at the side, nodded, and then looked at the launch button Xiao Tong.

"nineteen…"

Time passes in seconds.

When the last syllable fell and the word launch was shouted, Xiao Tong, who was in charge of launching, pressed the switch.

The next second, seven people stood together and hugged each other tightly.

Wait together.

…

"It's time!"

"Attention, it's already time!"

Someone shouted loudly, and at this moment, everyone's necks turned to the south.

Yang Xiaotao looked up and saw the time passing by.

The people around him could no longer sit still, stood up, and looked around.

Some people looked down at the time and shouted softly, as if they were counting down.

Mr. Wang and Mr. Qian also stood up, and the leaders around them also looked up at the sky.

"Over there!"

Suddenly, a person raised his hand and pointed at the sky and shouted loudly.

Everyone's eyes followed Fang Zheng.

A white line appeared in the southeast between them, traveling quickly toward the southwest in the air.

"that's it!"

Ran's father clenched his fists at his side.

Yang Xiaotao picked up the camera and took two pictures. The distance was too far and he could only see the black dots in front, but more of the long white lines in the back!

"The location is correct, the flight speed is correct, and this is what we can see here!"

Han Sanfeng suddenly ran out from the observation point, shouting loudly, and some people even raised their fists and waved them vigorously.

"Gone!"

Yang Xiaotao looked at the black dot disappearing in front of his eyes. In less than a minute, it was gone!

Only the remaining white lines in the sky!

"Put on your glasses and get ready!"

Ran's father suddenly spoke and then put on protective goggles. Yang Xiaotao quickly put them on when he saw it.

Then everyone looked to the west.

On the other side, Mr. Qian and others also wore glasses and looked nervously at the northwest sky.

Time passed by second by second.

Until a dazzling light burst out in the distance, and then I saw a black spot quickly enlarged, and in a short time, it turned into a huge black cloud.

In the field of view of Yang Xiaotao's camera, the black cloud was like a curtain, covering the entire sky.

"It looks good!"

Ran's father said with interest, this is already the second time!

"nice!"

Yang Xiaotao said absently, his whole body trembling.
