Mom and Dad, are you asleep?

Chapter 31 Mom and Dad, are you asleep?

It's 3 a.m.

Wu Guodong couldn't help but yawn, and gently nudged Liu Xuelan beside him with his elbow.

"It's three o'clock. Why don't you get some sleep? Otherwise you won't have any energy during the day tomorrow."

Liu Xuelan yawned as well, "Okay, then take a nap. Put the documents away carefully, don't lose them, they're all confidential."

The couple quickly packed their things and lay down on the mat to rest.

About ten minutes later, Wu Guodong's even snoring slowly began.

Wu Zu rolled over in bed and whispered, "Mom and Dad, are you asleep?"

There was no response from the bedside.

He asked softly, "Mom and Dad, I'm not feeling well."

However, after a long time, there was still no word from the parents.

After confirming that his parents were fast asleep, Wu Zu carefully stepped past them, tiptoed to the bag beside him, and took out the technical document.

He huddled under the covers, turned on his flashlight, and began to peruse the contents of the documents.

"As expected, they are researching a missile interception system!"

After briefly browsing the technical section of the document, Wu Zu gained a preliminary understanding of China's current missile defense system.

It turns out that China is developing a missile interception system, which uses the HQ-7 surface-to-air missile, China's second-generation air defense missile.

Wu Zu had some knowledge of the HQ-7 surface-to-air missile after he obtained the system.

It is a defensive missile developed based on a foreign missile, with all-weather combat capability, and is mainly used in the short-range air defense field of the army and navy.

However, the project has only been in the works for a short time and has not yet made significant progress.

Wu Zu's parents were in charge of the radar part, but due to a shortage of funds, the HQ-7 surface-to-air missile has not yet entered the actual research and development stage.

Wu Zu turned off the flashlight, stared at the document in his hand, hesitated for a moment, and finally stuffed the document under his pillow.

He lay in bed, staring at the ceiling, pondering what to do next.

Now that we have millimeter-wave radar, the key components of the missile interception system are basically in place. The remaining task is to study the HQ-7 surface-to-air missile.

He glanced at the meager points in his system account, then opened the system and found the list of military equipment.

Inside, there was a dense array of military equipment, weapons, and technologies, stretching as far as the eye could see, but none of them were available for purchase.

Wu Zu simply typed "anti-aircraft missile" into the search bar, and instantly, various anti-aircraft missile models and prices appeared before his eyes.

【Hq7地对空近程防空飞弹】：300积分【Hq9B远程区域防空飞弹】：1000积分【Hq19战略反导飞弹】：2000积分【————】

Looking at the numerous anti-aircraft missiles, Wu Zu couldn't help but sigh.

"Without points, you can't move an inch; you can't even afford the cheapest HQ-7 surface-to-air missile."

What should we do?

He lay in bed, legs crossed, and began to conceive of how to improve the millimeter-wave radar technology in the missile interception system.

Before he knew it, he drifted off to sleep.

When he woke up, he found that his parents had already left.

Soy milk and fried dough sticks were placed on the table, with a note left next to them.

"Grandma, Mom and I have to go now. We'll come back to see you at noon. Remember to eat breakfast."

After reading the note, Wu Zu felt a mix of emotions.

Researchers in China during this era had it really tough. They not only had to live in anonymity, but also often had to give up time with their families.

That's good, though, I'll be busy from now on!

So, after a quick wash and breakfast, Wu Zu took the technical documents to the library and began to study and improve the technical content.

Meanwhile, just as dawn broke, Wu Guodong and Liu Xuelan arrived at the phone booth and reported what they had learned the previous night to the dean.

After listening, the dean was very excited and praised him repeatedly.

"I didn't expect this trip to be so worthwhile! How about you guys thank me properly?"

Upon hearing this, Wu Guodong and Liu Xuelan exchanged a smile.

They really had to thank the dean; if it weren't for the dean's arrangements, the two of them would probably have already gone home empty-handed.

Who would have thought that I would run into my son here while working overtime, and discover that he has become an expert.

After hanging up the phone, Wu Guodong excitedly said, "Shumei, how about we go take a look at the tank our son modified?"

Liu Xuelan nodded and said, "Of course we have to go. I'm really curious to know what our son did to alarm the General Military Region!"

At that moment, Liu Xuelan suddenly remembered something and hurriedly asked Wu Guodong, "By the way, are all the technical documents properly stored?"

Wu Guodong patted his bag. "Everything's there, untouched."

"That's good. These are all crucial technical documents. Make sure to keep them safe. If they get lost, it will be a huge problem."

"Don't worry, we definitely won't lose it. Let's go check on the tanks first!"

"Hmm, we should definitely check out the tank our son modified. I heard that the Type 80 tank was discontinued because of this one!"

As they talked, the two arrived at the workshop where the tanks were parked.

Upon entering, they saw the tank, which resembled a steel behemoth, and were instantly captivated by its imposing appearance.

"Wow, that tank looks so impressive!"

"I never knew our son had this talent. I wonder if he takes after either of us!"

Next, they learned about some of the advanced technologies of the Type 99A main battle tank from the technicians, and were even more amazed by Wu Zu's abilities.

By the time I finished all that, it was already noon.

The couple went to the cafeteria, got their food, and took it back to their dormitory.

However, they found that Wu Zu was not there, so they decided to take advantage of this time to study millimeter-wave radar technology again.

Just as Wu Guodong opened his bag to take out the documents, he suddenly realized something was wrong.

What he took out of the bag was not technical documents, but a diary.

Wu Guodong was stunned.

"A diary?"

Immediately afterwards, he turned the bag upside down. Everything else was there, but the technical document was nowhere to be found.

Seeing this, Liu Xuelan was so anxious that sweat poured down her forehead.

"It must be that brat! He actually took the documents. If they're lost, that'll be a disaster! Didn't you say you checked them all?"

Wu Guodong looked helpless: "I did glance at it this morning, how did it turn into a diary? That kid is still so mischievous!"

"What are you all standing there for? Hurry up and go find someone!"

Wu Guodong and Liu Xuelan were extremely anxious. After making inquiries everywhere, they finally learned where Wu Zu had gone.

"What's that kid doing taking our documents to the archives? If the secrets are leaked, we'll be in big trouble!"

'

Wu Guodong looked worried, his brows furrowed into a tight knot.
