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

Old Qin took a deep breath, pointed at Zhou Weiguo, and said with a tone full of disappointment: "Zhou Weiguo, do you even consider yourself a citizen of China? The war with North Korea emptied our coffers. The foreign powers are always shouting outside that they want to deal with us. Yes, you did a great job in North Korea, you could even say you ended that war single-handedly, but do you know what that means?"

He became increasingly agitated, his voice trembling slightly: "From the Korean War to last year's Taiwan Strait issue, how many times has the US tried to use nuclear weapons against us? If it weren't for the Second Boss's mediation, we would have been utterly bullied long ago! It hasn't been easy for our Xia Kingdom to get to where we are today. We've all given our all to support you engineers and help you build our own 'sword,' our own 'big mushroom'! I only hate that all I know is how to fight. If taking my head could bring our country that sword, I'd be more than happy to do it! But what about you? What kind of time is this, still hiding things here?"

"Do you know what? Just a few days ago, the US fleet was swaggering around right on our doorstep. We could only rely on a few small gunboats to fight back, and dozens of our brave men were killed! Tell me, why? Because we had no weapons, no strength to fight them!"

Old Qin pointed at Zhou Weiguo's chest, his hand trembling with anger: "But you, full of knowledge, refuse to utter a word! Tell me, what are you hesitating about? What are you struggling with?"

Old Qin's rapid-fire questioning left Zhou Weiguo completely bewildered. He opened his mouth, but couldn't utter a word for a long time. He could only lower his head with a wronged expression and mutter softly, "I... I'm just afraid of being a guinea pig..."

"White mouse? What white mouse or black mouse?" Old Qin frowned, clearly not understanding the term.

Mr. Lin, who was standing nearby, quickly stepped forward and whispered in Mr. Qin's ear, "Mr. Qin, white mice are commonly used laboratory animals in foreign laboratories. Wei Guo is worried that if he stands out too much, he will be treated as an 'outcast,' and people won't accept it."

Old Qin was stunned for a moment after hearing this, then his eyes widened, and he pointed at Zhou Weiguo, cursing, "Bullshit! If you were really capable, we'd all treat you like an ancestor! If you could build a 'sword' that could take down America, I'd kneel down and acknowledge you as my grandfather! I've seen you hiding things all day long, and now what time is it, and you're still fussing over these trivial matters? I'm asking you, can't you stop hiding things and just say what you mean!"

Zhou Weiguo was so scolded that he almost buried his head in his chest. He quickly nodded and said, "Well, I'm not hiding anything. It's just that these things are all just my wild ideas. I'm not sure if they'll work."

Mr. Lin smiled and patted Old Qin on the back, trying to smooth things over, saying, "Old Qin, please calm down. He's still young and his ideas are bound to be a bit extreme, that's normal."

As he spoke, he turned to Zhou Weiguo, his tone softening considerably, "Weiguo, look at me. When did the country ever mistreat me after I returned from America? Didn't they always treat me like a treasure?"

Zhou Weiguo subconsciously replied, "You are the one who made the two bombs... um..." He quickly swallowed the words back, almost letting slip his future plans.

Seeing his hesitant expression, Old Qin's face turned pale with anger. Just as he was about to explode, Zhou Weiguo quickly waved his hands to interrupt, "No, no, no, Old Qin! I've thought it through! Uncle Lin, ask me anything you want to know, and I'll tell you everything I know! But let me make it clear beforehand, don't ask me how I came up with these ideas; I can't explain them myself."

Mr. Qin and Mr. Lin exchanged a glance, both seeing surprise in each other's eyes.

Mr. Lin immediately asked, "Then tell me, what exactly is this unsymmetrical dimethylhydrazine?"

Zhou Weiguo took a deep breath and said without hesitation, "Unsymmetrical dimethylhydrazine is an organic compound. I use it as a combustion agent, combined with dinitrogen tetroxide as an oxidizer. The two can burn violently upon contact, generating a particularly large thrust. Moreover, it has better performance than impulsive combustion, does not require additional ignition, can be stored for a long time at room temperature, is not afraid of impact and friction, and is easy to maintain."

"Is it really that effective?" Mr. Lin's eyes lit up, and he excitedly asked, "Then... this technique is..." But he remembered what Zhou Weiguo had just said and quickly swallowed his words back.

He then changed the subject, asking, "Since it has so many advantages, does it have no disadvantages?"

"It also has many drawbacks." Zhou Weiguo nodded. "Compared to fuels like alcohol/liquid oxygen and nitric acid/mixed amines, it has the best specific impulse, storage capacity, and preparation time, but it is highly toxic, expensive, and not environmentally friendly."

Mr. Lin, upon hearing the word "highly toxic," paid no heed. Instead, his face flushed, he grabbed Zhou Weiguo's arm: "You...you kid, you're not thinking of using it in a heavy-lift rocket, are you? I mean...a rocket that can launch intercontinental ballistic missiles thousands of kilometers away? Otherwise, you wouldn't need to specifically develop such a fuel!"

Seeing his excited expression, Zhou Weiguo nodded helplessly.

"Hiss," Old Qin and Mr. Lin gasped simultaneously, and the room instantly became so quiet that you could hear breathing.

Mr. Lin's eyes darted around, and seeing Zhou Weiguo's "what's the use" look on his face, he pressed on, "So, how far do you estimate the range of this missile will be?"

"1..." Zhou Weiguo started to speak subconsciously, but suddenly realized what he was saying and looked up at Mr. Lin. Good heavens, this was a tactic! But he had already told the truth.

Mr. Lin immediately smiled, stepped forward and put his arm around Zhou Weiguo's shoulder. Old Qin also quickly walked over and put his arm around Zhou's other shoulder. The two of them happily pulled him to the table.

"For the country, I understand!" Mr. Lin smiled, his eyes crinkling. "We're just having a casual chat, letting your imagination run wild, speaking freely, right?"

Zhou Weiguo rolled his eyes. He said that as if no one knew it.

Old Qin chuckled and said, "That's right, that's right. We're just listening to your thoughts. Maybe we can use them as a reference in the future. Don't worry, we won't pressure you."

Zhou Weiguo didn't say anything more. He simply pulled out a piece of paper, picked up a pencil, and started drawing as he spoke: "My idea is a two-stage liquid-fueled rocket engine. The first stage will be equipped with four high-thrust engines, each with a thrust of about 75 tons, for a total thrust of 300 tons. The second stage will use one 50-ton thrust engine to handle the final acceleration."

He drew a rough outline of the missile on a piece of paper and labeled it with the following data: "It is about 32 meters long, about 3.3 meters in diameter, weighs 180 tons at launch, has a range of about 1.2 kilometers, can carry a nuclear warhead, but can only be launched from a silo. In terms of guidance, it currently relies on inertial guidance, and the error may be relatively large at long distances."

He deliberately avoided mentioning integrated circuits, as there's practically no trace of this technology in China right now, so mentioning it would be pointless.

"Hiss," Old Qin stared at the numbers on the paper for a long time before muttering, "Now I think you're really bragging... The range of the Goose missile is only a little over 8,000 kilometers, and you dare to say 12,000 kilometers right off the bat? You're really daring to boast!"

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