Missile Defense System

Chapter 30 Missile Defense System

"Is there some mistake?"

Wu Guodong couldn't help but mutter to himself.

Liu Xuelan, standing beside her, echoed, "Yes, the host wasn't wrong, was he? How did our son end up here?"

"Are you sure it's our son?"

Wu Guodong shook his head: "I don't know, let's wait and see. What a coincidence it is to have the same name and look exactly alike!"

The couple were puzzled until Wu Zu stood on the stage, writing on the blackboard and explaining the technical points of millimeter-wave radar.

"The key to millimeter-wave radar lies in signal processing. Compared to traditional radar, it has a shorter wavelength, resulting in higher accuracy —"

Millimeter-wave radar transmits frequency-modulated continuous wave signals, receives reflected signals, mixes them with local signals, and then processes the signals to obtain information such as the target's range and velocity.

Listening to Wu Zu's clear and logical explanation, Wu Guodong and Liu Xuelan were astonished.

"Wow, he really knows a lot!"

"When did Ah Zu learn all this? There are probably only a handful of people in the whole world who can master this skill!"

The two exchanged a glance and quickly took out their notebooks to take notes.

The more I read, the more surprised I became. Some of the technologies mentioned later were world-class top technologies, which were precisely the radar technology problems that China urgently needed to overcome. Even foreign countries had made very little progress in this area.

Is this kid really their own son?

With great excitement, the two continued to take notes on the technical points explained by Wu Zu.

Throughout the auditorium, only Wu Zu's explanation and the rustling of notes being taken by the audience could be heard.

Before we knew it, two hours had passed.

Wu Zu put the chalk back into the chalk box, and everyone was surprised to realize that the class was over, showing expressions of lingering enjoyment.

Immediately afterwards, enthusiastic applause rang out.

"That's very well said!"

"That's great! After listening to Teacher Wu's explanation, I suddenly understood everything."

"I never imagined that millimeter-wave radar could be used so extensively! Maybe cars will even have these devices installed in the future!"

The applause lasted for about a minute before Wu Zu left the auditorium accompanied by several people.

Wu Guodong and Liu Xuelan exchanged a glance, hurriedly put away their notebooks, and struggled to squeeze out of the crowd.

Finally seeing Wu Zu's back, Wu Guodong excitedly shouted, "Son!!"

Before Wu Zu could react to the shout, the two guards protecting him immediately turned around, pointed at Wu Guodong, and yelled, "Who are you calling 'son'? This is Teacher Wu! Watch your words!"

Wu Guodong rushed over: "Comrade, I really am his father!"

Wu Zu turned around and froze the moment he saw Wu Guodong.

-

"Dad? Mom?"

Although he has traveled through time, the body still belongs to the original child.

Upon seeing his parents, his emotions and physical reactions were somewhat out of control.

When Wu Guodong saw Wu Zu, he was so excited that he rushed forward and hugged him tightly.

"Haha! It really is you! My good son, when did you become so amazing!"

Liu Xuelan, who was standing nearby, also rushed over and hugged Wu Zu tightly, tears welling up in her eyes.

"Grandma, Mommy misses you so much!"

Wu Zu felt a warm glow in his heart as he experienced this kinship that was both strange and familiar.

"Didn't Grandpa say you weren't coming back? Why—"

Upon hearing this, Wu Guodong and Liu Xuelan couldn't help but exchange a glance, both showing a helpless expression.

"We received a call from our superiors saying we needed to come here to hear an expert explain millimeter-wave radar, and we never expected that expert would be you!"

"Yeah, Ah Zu, what's going on? When did you learn these techniques? Didn't you always get the lowest scores in exams?"

Faced with his parents' questions, Wu Zu rolled his eyes.

"Uh—one day it was like I suddenly had an epiphany, and I understood everything all at once. Maybe it was the genes you passed down to me that suddenly kicked in!"

"Huh?" Wu Guodong was taken aback. "Genes can be suddenly activated? Is that even possible?"

Liu Xuelan, overflowing with maternal love, said, "Who cares about being excited or not? I'm happy enough just to see my son. Let's quickly find a place to eat something and have a good chat."

"Yes, yes, let's eat first and have a good chat with our son."

Afterwards, the family of three went to Wu Zu's dormitory and chatted over a few dishes.

"Azu, tell your mother the truth, how did you get here?" Liu Xuelan asked.

Wu Zu picked up a piece of food and said, "It's a long story, it all started when we were building tanks."

"What?" Wu Guodong's eyes widened. "Build tanks?"

Wu Zu nodded: "Yes, my grandfather hid a tank under the factory. I made some minor modifications, but it was accidentally discovered. Then I went to the military region, where they asked me to explain the relevant technology. This millimeter-wave radar is one of the technologies in the Type 99A main battle tank."

"Hiss—" The couple gasped.

They had heard about the Type 99A main battle tank at the research institute, but they never expected that their own son would be the one to build it. It was unbelievable!

At this moment, Wu Guodong suddenly remembered something and said to Wu Zu, "By the way, could you tell us more about millimeter-wave radar? We are also researching this technology now."

Liu Xuelan also realized what was happening and quickly nodded, "Yes, yes, millimeter-wave radar is extremely important to our current research direction!"

Wu Zu nodded: "No problem! It's all our own business, I'll teach you."

After finishing their meal, the two moved chairs over, took small notebooks, and began to learn millimeter-wave radar technology from Wu Zu.

They studied until 10 p.m., and Liu Xuelan checked the time and quickly said, "It's getting late, let Azu go to sleep!"

Wu Guodong then realized, "Right, right, time to sleep!"

Helpless, Wu Zu could only lie on the bed and close his eyes, but he couldn't fall asleep no matter what.

In his previous life, as a programmer, he had long been accustomed to staying up late and had almost never slept before 3 a.m.

About half an hour later, Wu Guodong's voice came from the room: "Xuelan, I can't sleep."

"Me too, all I can think about is millimeter-wave radar."

"Yes, Ah Zu has done a great job this time. Millimeter-wave radar is crucial to our missile defense system!"

"That's right, why don't we take this opportunity to take out the data and study it?"

"I think it'll work!"

The couple quietly got up, shielded themselves from the lamplight, and resumed their technical research.

Unbeknownst to them, Wu Zu was not asleep at all. Hearing his parents' conversation, he was shocked. He never expected that his parents were actually working on a ballistic missile defense system.

At this moment, Wu Zu's eyes suddenly lit up.

Missile defense system — Is there anything I can do about it?
