Rongrong complained in a low voice, and then she saw Ran Qiuye walking over and burying his head in Yang Xiaotao's back.

"Get up, I almost asked someone to help take me to the hospital."

Ran Qiuye walked up to him with a glass of water, then glared at the little guy who complained, and the three little ones ran out in a hurry.

Yang Xiaotao took the water glass and took a sip, then shook his head again, and then asked, "How long have I been asleep?"

"I came back yesterday morning and spent the whole day and night."

"So long?"

"No."

Yang Xiaotao drank the water, and then looked at Ran Qiuye, "I slept for such a long time, is there nothing wrong?"

Ran Qiuye's eyes turned red, "What do you think?"

"Aside from scaring me, what else can you do?"

Hearing this, Yang Xiaotao was moved, put down the cup, and hugged the people around him.

"This time is special, don't worry, I promise it won't happen again in the future."

"Who gave you a guarantee?"

Ran Qiuye was hugged tightly by Yang Xiaotao and leaned against his chest.

"I'm not against you working, but you should also take care of your body."

"If you are gone from this family, what will we, the four of us, do in the future?"

Yang Xiaotao listened quietly, but hugged Ran Qiuye tighter.

After breakfast, Yang Xiaotao did not go to the machinery factory.

Anyway, what needs to be done has been done. Today happens to be the weekend, and Yang Xiaotao plans to spend time with his family.

As the saying goes, one spring rain comes and another warm one comes. After the rain, the sky clears, and the sun looks like a different person. It takes off its winter clothes and emits a blazing light.

The family learned from Grandpa Sun, and they all took off their heavy cotton clothes and put on dry coats. Then two bicycles and two dogs followed them out of the courtyard and came to the edge of the West Sea.

There were a lot of people traveling around, and there were groups of people every now and then. The whole family was together, and it was very lively.

Yang Xiaotao found a place under a big tree and placed the fruit cakes he had brought. Then he took out the prepared kite and led the child to an empty place.

With lack of food and clothing these days, the kite made by Yang Xiaotao was naturally not made of cloth, but made of newspaper and bamboo.

Of course, the one who contributed the most here was classmate Xiaowei.

Yang Xiaotao has made two such kites in total. Although the newspapers are of different colors and they don’t look very good, they are good if they can fly.

With the east wind, two swallow-shaped kites were launched into the sky.

Duanwu and Miaomiao each pulled one, and the two younger ones clapped their hands and shouted after each other, with their heads raised high, so they were not afraid of neck pain.

"Look, we are the only ones with kites around."

Yang Xiaotao couldn't help but feel proud when he saw a group of children surrounding the Dragon Boat Festival.

Ran Qiuye was cutting fruit with a knife. When she heard her man showing off, he hurriedly hummed to show that he was honored.

"Watch your kids, I'm going fishing. Let's eat fish tonight."

Yang Xiaotao said something to Ran Qiuye, then picked up the fishing rod and walked to the water.

While Yang Xiaotao was leading his family to relax in the West Sea, the final experiment of the turbojet stamping machine was about to be carried out in the Seventh Machinery Department.

Father Ran's eyes were red, he hadn't slept for two days and two nights, and the fatigue on his face was visible to the naked eye.

Others around him weren't doing much better either.

Except for Comrade Lao Wang, who couldn't bear it and slept for half the afternoon, everyone else barely slept a wink.

"Old Qian, you go and take a nap, I'll watch over here."

Mr. Wang saw Mr. Qian constantly drinking water to refresh himself, and came to the side to persuade him.

Mr. Qian shook his head, "No need. It will be assembled soon. The last step is to make it happen. Let's see if it succeeds."

After hearing this, Mr. Wang said no more. He knew the character of the other party and no one could stop him from what he decided.

"It stands to reason that if there is no problem with the ramjet engine, then we will not have any problems."

"Right, Lao Ran."

Qian Lao seemed to be speaking to himself, but also to Ran's father who was standing aside.

Ran's father hummed, his lips were a little dry, but the joy on his face flashed across his face.

The turbojet stamping machine designed by Yang Xiaotao has passed various tests and its performance has met the requirements.

Now comes the most important part, testing the speed.

While I was thinking about it, everything was ready.

"start."

Following Qian Lao's order, the staff not far away immediately began to open the switch and start the test.

Everyone looked nervously through the bunker behind the engine.

Slowly, slowly, suddenly someone covered his mouth, not daring to make a sound, but unable to suppress it.

Father Ran rubbed his eyes and looked at the pillar of fire emerging from the darkness in front of him. There seemed to be many triangles hidden in the pillar of fire, and then the color began to change.

He knew that this was the Mach ring.

The Mach ring only appears when the speed of sound is exceeded.

He knew that the appearance of this thing meant that this engine had reached supersonic speed requirements.

Mr. Qian on the side has already started counting, one, two, three...

Mr. Qian also knows that the number of Mach rings does not directly represent the thrust of the engine, but under the same circumstances, the more Mach rings, the greater the thrust.

Farther away, Mr. Wang was still watching the colorful changes, feeling an urge in his heart that he wanted to shout but didn't dare to.

So beautiful, so beautiful.

Yeah~~~

Suddenly, I don't know who couldn't hold it back and broke this rare peace.

Then violent shouts filled the entire experimental area.

People nearby hugged each other, jumped and jumped together.

"Successful."

Ran's father looked at Mr. Qian and said a thousand words, his eyes blurred with tears, just for these three words.

Mr. Wang came to the front and hugged the two of them tightly, "Yes, we succeeded."
Chapter completed!
