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

Old Qin chuckled and joked, "What good stuff have you come up with this time? When Xiao Zhang reported to Minister Song, he immediately asked for a tank, saying he wanted to test your new weapon. It really startled us!"

Zhou Weiguo glanced at Brother Zhang with a wry smile, while the latter scratched his head somewhat embarrassedly.

Just then, a man stepped out of the jeep from the other side. The moment Zhou Weiguo saw him, his heart skipped a beat. Before Old Qin could speak, he excitedly went to greet him: "Young man Zhou Weiguo greets Mr. Lin!"

Mr. Lin was taken aback at first, then smiled and said, "Young friend Zhou Weiguo, do you know me?"

Overwhelmed with emotion, Zhou Weiguo stammered, "When you returned to China last year, I read about your deeds in the newspaper. I especially admired your decision to give up a comfortable life abroad and return to build our motherland!"

Old Qin walked over and explained with a smile, "I didn't expect you to know Mr. Lin too. We were discussing business with Director Song when he received a call from Xiao Zhang, so we decided to come along. Mr. Lin kept talking about it the whole way, insisting on meeting you, this young talent."

Zhou Weiguo quickly waved his hand: "Compared to Mr. Lin, how can I be considered a genius!"

Mr. Lin said earnestly, "For the sake of the country, don't underestimate yourself. I've carefully studied your rifle and sniper rifle design drawings, as well as the actual prototypes. Both their design concepts and combat performance have reached world-class levels. Young man, you can't be too modest!"

Old Qin noticed something amiss in the direction of the workshop and asked, "Weiguo, what's going on over there?"

Zhou Weiguo then realized what was happening and subconsciously looked at Vice Minister Wang. He saw Zhou Dapao and Brother Zhang standing next to Vice Minister Wang, talking about something, while Vice Minister Wang's face was terribly gloomy.

Upon hearing Elder Qin's question, Vice Minister Wang quickly replied, "For the country, you take Elder Qin, Minister Song, and Mr. Lin to test the new weapon first. I'll handle things here."

Seeing the almost pleading look in Deputy Commander Wang's eyes, Zhou Weiguo swallowed back the words he was about to say. He nodded and said to Brother Zhang, "Brother Zhang, have Da Niu or Er Niu move everything to the firing range."

Old Qin gave Vice Minister Wang a meaningful look, then beckoned everyone to get in the car, adding, "Xiao Zhang, remember to bring Comrade Natasha along too." After saying that, the group drove to the firing range.

On the way, Zhou Weiguo and Mr. Lin had a very pleasant conversation. Mr. Lin even asked about his interest in missile research.

Zhou Weiguo knew that he still possessed the technology for the HQ-2B air defense missile system and the CA30A heavy-duty truck, but he was also worried that if he revealed it, he would be transferred to the Northwest.

After all, in the steel rolling mill and the courtyard house, maximizing profits could only be achieved through the system. So, he could only give vague answers and change the subject.

Upon arriving at the firing range, Zhou Weiguo was surprised to find a tank parked in the distance.

He looked at Old Qin and asked incredulously, "You're not really going to test my anti-tank weapon with a tank, are you?"

Old Qin chuckled and teased, "What's wrong, kid? Scared too? No confidence?"

Zhou Weiguo shook his head helplessly: "I just finished making this weapon, how can I guarantee its effectiveness! It's all Brother Zhang's fault. I just said I wanted a piece of tank armor or a steel plate, and he brought all of you here instead!" This made everyone burst into laughter.

Old Qin explained, "This is an American M46 tank captured during the North Korean War. They bullied us terribly back then. Anyway, we've already finished researching it, so it's a good opportunity for you to practice."

About 15 minutes later, two jeeps sped up. Zhang Ge, Natasha, Dashan, and Erniu got out of one of the jeeps, while the guards in the other jeep were busy unloading weapons.

Without delay, Zhou Weiguo picked up the OSV-96 rifle and loaded it with bullets.

Zhang was eager to start shooting, but Zhou Weiguo stopped him: "Zhang, if this gun explodes, no matter how you hold it, you won't be able to save your arm. Let's be careful."

He found a table, carefully secured the gun, loaded the magazine, and tied a rope to the trigger.

After roughly aiming at the tank about 100 meters away, he quickly retreated to a safe distance and pulled the rope.

"Bang bang bang bang bang," five shots rang out, and all the bullets in the magazine were emptied.

To Zhou Weiguo's surprise, Old Qin was the first to rush out. When he caught up, he saw Old Qin staring in shock at the dents on the tank's armor, and Brother Zhang also had an incredulous expression.

Zhou Weiguo was somewhat disappointed: "I didn't expect it to be so weak, just this little dent."

Old Qin was both amused and annoyed: "What are you thinking, kid! This is an American M46 tank, with armor thickness of 30-85 millimeters. A regular rifle shot would only chip off a layer of paint at most. Look at this dent, aren't you satisfied?"

Mr. Lin carefully examined the shell crater and exclaimed, "Weiguo, your gun is amazing! It would have pierced through ordinary steel plates or armor thinner than 15 millimeters. What's the range of this gun?"

Zhou Weiguo scratched his head: "According to my design, the effective range is 2000 meters, and the maximum range is 2500 meters."

Upon hearing this data, Elder Qin, Minister Song, and Mr. Lin all gasped in shock, staring at Zhou Weiguo in astonishment.

Old Qin exclaimed, "You've brought us another treasure!"

Zhou Weiguo said with a wry smile, "Treasure, my foot! It can't even break a tank." But no one paid any attention to his complaints.

What followed was round after round of test firing. After firing about 50 rounds, Brother Zhang finally couldn't hold back any longer, rushed over, disassembled the weapon, and lay down to aim at the tank.

After waiting for a long time without hearing a gunshot, Zhou Weiguo was wondering what was going on when suddenly a loud "bang" was heard, and a violent tremor came from the tank in the distance.

Upon closer inspection, the tank's tracks had been broken! Then, four more gunshots rang out.

Brother Zhang exclaimed excitedly, "For the country, you've created a divine weapon!"

Zhou Weiguo joked, "It's just a blind cat catching a dead mouse, breaking a conveyor belt, is it really necessary to get so worked up?"

Brother Zhang laughed and scolded, "You have terrible eyesight, kid!"

Curious, the crowd gathered around the tank, and another wave of amazement ensued.

Old Qin even climbed onto the tank and crawled into the driver's compartment to check. When he came out, he was shocked: "The observation window was shattered. If there was anyone inside, they certainly wouldn't be alive!"

Mr. Lin greeted everyone, "Mr. Qin, come and take a look here."

When everyone went over to take a look, they found that the engine compartment had been shot through!

After repeated testing, it was discovered that the gun could only penetrate the tank's armor if it hit the weakest point.

Zhou Weiguo, too lazy to bother anymore, smiled and said to Brother Zhang, "Brother Zhang, don't bother trying, let me show you the 'fire poker'."

Zhang Ge excitedly ran to the table and picked up the RPG rocket launcher. As usual, the two secured the weapon, loaded the armor-piercing rounds, retreated to a safe distance, and then pulled the rope.

"Whoosh— Boom!" With a loud bang, the rocket accurately hit the side of the tank.

Everyone rushed over, speechless with shock.

Looking at the breached side armor, Old Qin sighed, "Ah! If we had had this treasure back then, let alone our tanks, we wouldn't have needed our soldiers to risk their lives fighting for even American tanks!"
