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

Mr. Lin stared intently at Zhou Weiguo, as if he had something to say.

Zhou Weiguo felt uncomfortable being stared at, but thinking of the Northwest, he could only pretend not to see it and continue testing.

The next eight rockets penetrated all but the thickest armor on the tank's front with a single hit.

In contrast, the final PKM general-purpose machine gun test was much less impressive.

Although it possesses sustained firepower and powerful lethality, Zhou Weiguo felt it was nothing special.

Zhang Ge and Chief Engineer Song, however, were quite fond of the gun and asked to take it away for research, which Zhou Weiguo readily agreed to.

After everyone had finished testing the firearms, they lit cigarettes and chatted while puffing away.

At this moment, Natasha got out of the jeep and asked, "Mr. Qin, Colonel Zhang just said you asked me to come over. What's the matter?"

Old Qin quickly said apologetically, "I'm sorry, Comrade Natasha, we were so focused on testing the weapons that we forgot you were here."

Natasha shook her head: "It's nothing. I was just a little tired, so I lay down in the car and slept for a while."

Old Qin continued, "Mr. Lin has something he'd like to ask you."

Mr. Lin stepped forward and said, "Hello, Comrade Natasha. I'd like to ask if you have any research on missiles?"

After a moment's thought, Natasha replied, "Mr. Lin, I haven't specifically studied missiles, but I have been in charge of missile materials work. Which part do you want to ask about?"

Mr. Lin politely asked, "Miss Natasha, I would like to ask, if Xia Country wants to manufacture ballistic missiles, do you have any specific suggestions? For example, regarding materials, fuel, etc."

Natasha thought for a moment and said, "Given the current situation in Xia Country, the simplest solution is to use high-strength aluminum alloy as the main material and ethanol combined with liquid oxygen as the oxidant. This requires the least technical expertise and is easier to take the first step."

Mr. Lin's eyes lit up, and he continued to press, "Miss Natasha, you're talking about the situation in Xia Country. If we disregard the limitations of that situation, what would be the most advanced solution?"

Natasha calmly replied, "That depends on two situations: one is the most advanced in practical application, and the other is the most advanced in theory."

Mr. Lin asked with a face full of curiosity, "Could you please enlighten me, Comrade Natasha?"

Natasha glanced at Zhou Weiguo, a glance that left him completely bewildered. He thought to himself, "Wait, what's with that look? Do you think I'd stop you from speaking?" He then glared at Natasha fiercely.

Seeing this, Mr. Lin became anxious and quickly looked at Zhou Weiguo: "Weiguo, quickly tell Comrade Natasha that this is very important to us."

Zhou Weiguo glared at Natasha: "Speak up! Mr. Lin has already asked!"

Unexpectedly, Natasha looked at him with a mischievous grin and said, "It's not like I haven't told you before. Why don't you tell Mr. Lin?"

These words stunned Zhou Weiguo. He pointed at himself, almost swearing. But he could only stare intently at Natasha, his eyes seeming to say, "When the hell did you tell me that?"

When he thinks about missiles, data about the HQ-2 automatically comes to mind.

He glanced at Mr. Lin, whose face was full of hope, then turned to Natasha, who had a mischievous grin on her face, and could only gather his thoughts before saying, "As for fuel, it definitely needs to be divided into solid fuel and liquid fuel, each with its own advantages and disadvantages. For liquid propellant, we could consider using unsymmetrical dimethylhydrazine + nitrogen tetroxide; if using solid propellant, we could consider using nitrocellulose and nitroglycerin as a base, adding ammonium perchlorate and aluminum powder, which would generate energy better and be more suitable for ballistic missiles. As for the main materials, Natasha hasn't taught me yet, you should ask her."

Mr. Lin looked at Zhou Weiguo with delight. He not only looked at Zhou Weiguo, but also glanced at Elder Qin and Minister Song from time to time.

The two men then stared intently at Zhou Weiguo, their eyes seemingly saying, "You finally gave yourself away."

Feeling goosebumps from everyone's stares, Zhou Weiguo stepped forward, pulled Natasha aside, and said, "You should talk to Mr. Lin. I'm just a novice, don't you think?" As he spoke, he pinched Natasha's butt hard.

To his dismay, Natasha, this "fairy," let out a soft moan and leaned against him.

Seeing Natasha's reaction, Zhou Weiguo had only one thought in his mind: "I have something to say, but I don't know if I should say it. Damn it, I'm doomed."

He looked at Elder Qin and Minister Song, who were looking up at the sky from either side; even Mr. Lin suppressed his curiosity and lowered his head to ponder.

Zhou Weiguo quickly moved away from Natasha and urged, "Natasha, explain to Mr. Lin quickly, otherwise he'll get angry."

Mr. Lin quickly waved his hand: "No, no, how could that be! Comrade Natasha, don't listen to Weiguo's nonsense. We can talk later. I need to process what Weiguo just said."

Natasha clearly understood Zhou Weiguo's meaning. She gave him a playful glare and continued, "Mr. Lin, the most advanced ballistic missile in the world right now is undoubtedly our R-16 intercontinental ballistic missile. Its body is made of aluminum-magnesium alloy, balancing lightweight and structural strength; it uses a storable liquid propellant, specifically a combination of nitrogen tetroxide and unsymmetrical dimethylhydrazine, which allows it to maintain a 30-day operational readiness state after refueling. It is undoubtedly the most powerful intercontinental ballistic missile in the world. However, it is not theoretically the most advanced..."

Natasha then engaged in a series of in-depth discussions with Mr. Lin.

Zhou Weiguo remained silent and quietly stepped aside. He was still shaken, afraid that Natasha would try to extort money from him again like before.

Mr. Lin displayed a strong thirst for knowledge, much like a diligent student. Even on the way back, he maintained a lively conversation with Natasha.

Throughout the journey, Old Qin, Director Song, and Mr. Lin all looked at Zhou Weiguo with a strange gaze. This made Zhou Weiguo feel extremely uneasy, constantly worried that he would be conscripted, so he could only lower his head and remain silent.

After everyone had dinner at the steel rolling mill, Zhou Weiguo couldn't wait to get in his car and drive away with Natasha.

Watching Zhou Weiguo flee in disarray, the three old men, including Qin, exchanged a smile and couldn't help but burst into laughter.

At this moment, Mr. Lin hesitated for a moment before speaking, then said, "Professor Qin, Weiguo is indeed a rare scientific research talent. Do you think it's possible for him to participate in our missile and subsequent big mushroom missile development projects?"

Old Qin pondered for a moment, then slowly said, "I think Weiguo seems to have some concerns. How about this, I'll find an opportunity to talk to him. These things can't be forced. If he's willing, he can join; if not, as long as we provide sufficient support, the steel mill can fully meet his current development needs."

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