I painted an aircraft carrier on the courtyard house for Dongda University.

Upon hearing this, Zhou Weiguo suppressed his excitement and nodded with a forced expression.

Natasha rolled her eyes at him, then fell into deep thought. After a while, a hint of worry flashed in her eyes.

He asked, "Young master, do you think we might have already changed the course of the future? I've given so many metal formulas and raw material technologies to Xia Kingdom, plus this oxygen top-blown converter. Although it's only 30 tons now, with that technological foundation, Xia Kingdom should be able to build converters with capacities of over 100 tons in a few years. Do you think that would prevent the Great Leap Forward? And without the Great Leap Forward, wouldn't there have been no such severe disasters?"

Zhou Weiguo fell into deep thought, a feeling he couldn't quite describe welling up inside him. He realized that what Natasha said might actually be a possibility.

Just then, urgent shouts came from outside the door: "Uncle! Uncle! Are you back? Open the door! Uncle, why did you lock the gate when you came back? Open the door quickly!"

Zhou Weiguo immediately recognized He Yushui's voice and quickly started tidying up with Natasha.

He Yushui outside the gate was like a little firecracker, banging on the gate incessantly, her urgency making it seem as if she would miss something of paramount importance if she delayed even a second.

After Zhou Weiguo and his companion finally got everything sorted out, Zhou Weiguo hurriedly opened the courtyard gate.

Standing outside the door were He Yushui, He Yuzhu, and a girl who looked to be about fourteen or fifteen years old.

What frustrated him even more was that the courtyard was just as lively as last time, with Qin Huairu, the three older women, and a group of neighbors all craning their necks to look into the east side of the courtyard.

When everyone saw the red car parked at the entrance of the east courtyard, they immediately began to whisper among themselves, their excitement evident.

Qin Huairu, in particular, had a greedy glint in her eyes.

But when she saw Natasha gracefully walk out of the room in a dress, a hint of jealousy flashed across her face.

He Yushui skipped and hopped as she introduced, "Uncle, this is my classmate Yu Haitang! Haitang, this is my uncle. He's really amazing; he's the head of the technical department at the steel rolling mill!"

Zhou Weiguo looked at Yu Haitang and found that the girl was seriously sizing him up. He then said, "Come in and have some fun."

As he spoke, he ushered the three into the east courtyard and quickly closed the gate, afraid that the curious eyes outside would slip in again.

As soon as Zhou Weiguo led the two into the courtyard, Natasha came to greet them.

He Yushui cheered and threw herself into Natasha's arms: "Uncle... um... Aunt!"

Natasha laughed and hugged her tightly, then spun her around.

After He Yushui landed, she realized that Yu Haitang was gone.

Turning around, I saw Yu Haitang standing next to the red car, looking longingly at it, her expression both wanting to touch it and too timid to do so, which was quite adorable.

He Yushui excitedly ran over, turned to Zhou Weiguo, and said, "Auntie, this car is so beautiful! I want to ride in it!"

He Yuzhu looked at Zhou Weiguo in shock: "Uncle, is this meant for Aunt?"

Zhou Weiguo smiled and nodded, then asked in a low voice, "Last time Yushui said he was bringing Yu Haitang and her sister to our house. Did you meet them? How did it go?"

He Yuzhu pondered for a moment and said, "It seems so. She even asked me for the key to your east wing. But I told them not to go into your bedroom. You know, I've been cooking for you at the factory lately and haven't been home much."

Zhou Weiguo slapped his forehead, only then realizing that he hadn't been home much in three months, and He Yuzhu had been busy at the factory from early morning to late at night.

Just as he was feeling frustrated, he caught a glimpse of Yu Haitang touching a car, and suddenly an idea came to him.

"Zhu Zi, don't go to work today, come with me."

Zhou Weiguo glanced at He Yuzhu's greasy hair and added, "Go home right now, clean up, wash your hair, change into your best clothes, and then come find us."

.......................

On the other side of the lake, the head manager, the second manager, and Old Qin sat upright, while Director Wang and a bespectacled comrade had just finished their report.

Everyone was excited, and the head manager slammed his fist on the table, exclaiming repeatedly, "Excellent! Excellent! Excellent! With this precious converter, our Xia Kingdom will never have to worry about a lack of good steel again! Little Wang, tell me in detail how you plan to use this converter?"

Director Wang immediately responded: "Boss, during these three months of converter development, Comrade Natasha has shared everything without reservation. All manufacturing processes were completed by our own people. From furnace body materials and insulation materials to oxygen lances, she provided the parameters or drawings for our people to manufacture. Now, the complete set of converter drawings has been sealed in the steel rolling mill. In these three months, we have trained no fewer than 80 converter experts for Xia Country. I firmly believe that with national support, these 80 experts will be able to quickly promote converter technology throughout the country. Currently, the steel rolling mill plans to continue testing the existing converter, and once the testing is completed, we will begin trial production of a 60-ton converter."

Upon hearing this, the head manager was visibly excited, smiling and exclaiming, "Excellent! Very good! Keep up the good work! I hope to see converters all over the country as soon as possible. You're absolutely right, Comrade Natasha's kindness to our Xia Kingdom is immeasurable! Not only air converters, but also sponge titanium and high-temperature alloys have been trial-produced according to the technical data she provided, and mass production is now being prepared. Comrade Natasha is truly selfless towards Xia Kingdom!"

The second manager echoed this sentiment: "Indeed! I can't even imagine what earth-shattering changes Xia Country's industry would undergo if we could thoroughly master all the technologies provided by Comrade Natasha."

"Indeed, Comrade Natasha's contributions are unparalleled. Young Wang, you are entrusted with Comrade Natasha's daily care. Remember, as long as she is in Xia Kingdom, this meritorious woman must not suffer the slightest injustice. If she wants to pursue technology, fully support her; if she doesn't want to, even if she just wants to travel to Xia Kingdom's famous mountains and rivers, do not stop her, and certainly do not demand that she undertake new projects. Just the stack of technical materials she provided alone could accelerate Xia Kingdom's development in related fields by at least 20 years!"

Then, the head manager turned to Old Qin: "Old Qin, could you please make a trip for me and deliver my thank-you gift to him, so that he can properly express my gratitude?"

Old Qin nodded in agreement, then remembered something else: "What about that kid Zhou Weiguo? He's a rare talent. I never expected that his sworn sister would do the country such a big favor."

The head manager smiled and waved his hand, "We shouldn't interfere too much in the affairs of young people. However, since they have made a contribution, they should naturally receive the rewards they deserve."

P.S.: Please urge me to update more and give me good reviews. Thank you!
