A nation's industrial development begins with junior engineers.

The thing, Chinese name: Golden Lips

This is a "hero" who has been monitoring the U.S. ambassador for eight years.

Jiang Xia pulled Wang Kui aside, made a shushing gesture, and pointed to the phone next to him.

He took out a screwdriver and carefully pried the thing open.

Wow, it truly is a masterpiece by a master. There are as many as seven or eight scattered parts inside. I really don't know how the Russians designed such a thing.

Wang Kui picked up the phone, his eyes widening as he watched Jiang Xia disassemble the device.

Damn, I thought the little brat was going to be honest, but I never expected there was something hidden inside a metal nail!

"Hello, guesthouse, what do you need?"

"Hmm, there's a lot of sand on the bed. Have someone with the badge come and clean it up!"

"Okay, the relevant personnel will be here shortly." The person on the other end of the phone was very quick-witted.

By the time the technician with the badge arrived, Old Wang had already found two more metal nails from other places.

……

In the open space in front of the guesthouse, Jiang Xia and Lao Wang sat side by side, watching the soldiers busily working.

After a long while, a middle-aged man who called himself Director Zhao came up to the two of them, extended his hand, and shook hands with Jiang Xia.

"A full investigation has begun. The outer shell of this thing is made of copper, so it's difficult for ordinary metal detectors to detect it."

"The soldiers have already begun scouting outside to see if there are any suspicious individuals carrying high-powered radios. It's Engineer Jiang, you..."

"Uh, you want me to prove my innocence?"

"You're overthinking it. You won't be enjoying this high standard of treatment from the Russians today. If you don't mind, come sleep in my dorm for a while!"

Upon arriving at Director Zhao's dormitory, the carefree Jiang Xia fell asleep the moment his head hit the pillow.

Old Wang shook his head as he looked at the sleeping Jiang Xia. The little brat was really exhausted.

Then, Old Wang pulled Director Zhao aside with a serious expression, insisting that Director Zhao outline a set of rules and regulations. After all, in a unit like this, encountering such a situation is a matter of utmost importance.

But why does Director Zhao look so relaxed?

Director Zhao shrugged: "Remember that guy from the other factory you caught? He confessed!"

"His first instruction to the people there was to come and retrieve this batch of goods."

"Furthermore, those two swallows were caught too. Their main task was to monitor the experts who came to provide support, to see if they said anything they shouldn't have..."

"They caught them? They haven't returned to their country yet?"

Director Zhao grinned silently, and Wang Kui suddenly understood.

I wonder which guy had such incredible courage to pull this off in the League of Legends.

"The sample has been shown to the experts. The design is quite ingenious, but the transmission distance is limited. This proves that the two swallows weren't lying. After all, our stuff is all down there, and the yellow sand is the best barrier."

"Hey, is this anything to do with the little brat?"

"Of course!" Director Zhao turned around. "We still need to get a base medal."

After the noise subsided, the base returned to calm.

……

The dog, carrying the connecting pipes, skillfully entered a top-secret area and found Old Jiang, who was still working diligently.

"Old Jiang, Old Jiang, look what this is!"

Old Jiang looked up. "Hey, where did you get this? Take it to Secretary Xie and the others to see, I'm too busy to handle this!"

Tsk, why don't you test it yourself? You know, it was your son who did this!

The dog was scratching its head and prickling its ears. "Go and get tested! If you pass, I can give you the stuff under the guise of celebration!"

"Secretary Xie and the others said they found the cause and have rushed back to the outlying factories to re-test it. They saw you were engrossed in calculating and didn't notify you."

"Hey, you mutt, where did you find this pipe? It looks pretty nice."

Jiang's deputy, Lao Huang, picked up the conversation and casually grabbed a pair of calipers to take measurements.

The more I tested, the more alarmed I became.

"Damn it! Is this ruler broken? How come they're all reading the same number?!"

Upon hearing this, Old Jiang stretched and handed over a box: "Measuring tools need to be sent to the metrology station for inspection periodically! I've told you so many times. Take a look at this; I just picked it up when it came in."

Old Huang solemnly took the box, took out the vernier caliper inside, and held it up to the light before measuring. Then he took out a piece of white paper and traced it between the probes.

"Incredible! This mongrel, is this something Secretary Xie and his team just created?"

"Quick! Lao Jiang, get to the testing platform!"

Seeing his partner's excited expression, Jiang Chuntian pushed aside the calculation draft in front of him and said, "Let's get started!"

The little loudspeaker on the wall started blaring again:

"Test 412 of Corrugated Pipe No. 1 begins. Unauthorized personnel please leave the work area."

"System will start after one minute of pressure buildup!"

After a while,

"The pressure test for bellows No. 1 has passed; bellows No. 2 is now undergoing testing..."

And so, the announcement that the test had passed kept coming from the loudspeaker.

When the fourth type of corrugated pipe was finally tested, some personnel violated procedures and crowded the narrow passage.

Although the laboratory door was tightly closed, everyone seemed to have X-ray vision, staring intently at the round glass window on the steel door.

Some who couldn't squeeze in stared intently at the small speaker on the wall.

"Number four, the most important pipe!"

"Passed! Passed! It's been 665 times already..."

"It'll work! No pipe has ever passed the test continuously before. This time it should work!" The technician beside them loudly reassured everyone.

It's less about encouraging others and more about giving yourself psychological comfort.

Inside the laboratory, Lao Jiang's hands were also trembling.

An unintentional test turned out to be a complete success. This happiness came a little too suddenly. Old Jiang, who was used to pipes breaking, found his hands somewhat unresponsive.

"Dawdling!"

The dog got anxious and grabbed Lao Jiang's hand, pressing it down.

"What can you possibly do with just one button? If it works, great; if not, just try again. Anyway, the kid seems to be doing it pretty easily!"

Old Jiang glared at the stray dog, not bothering to say anything to blame it, his attention completely drawn to the appearance in front of him.

"Pressure is increasing; pressure has reached the design level!"

"Pressure is being continuously increased, and the pressure has reached the design limit."

"Old Jiang?"

"Maintain the upper limit, start the timer!"

Old Jiang pressed the stopwatch he always carried with him; the ticking sound of the stopwatch was like a heavy hammer, striking people's hearts.

For a moment, everyone held their breath.

"Continue for one minute, and visually inspect the sample for any intact appearance with no gas leakage!"

"Five minutes in a row, perfect!"

"Seven minutes, all set!"

Closer, closer, hang in there, hang in there...

Old Jiang had already raised his hand, staring intently at the stopwatch.

"Seven minutes and thirty-five seconds!"

We've reached the design line!

Just as Lao Huang was about to cheer, Jiang Chuntian reached out and pinched his lips.

"Gah?"

"The teacher gave the instruction that if the accuracy improves by 0.2, then the pressure duration should be 8 minutes or more. Don't shout!"

What does it mean for a second to feel like an eternity? Old Huang, whose mouth was being held shut, now deeply understands this feeling.

Hold your breath, close your eyes, and count silently in your mind.

No, we've already counted to 100, isn't the time up yet?

Old Huang, who was almost suffocating, looked at Jiang Chuntian.

Jiang Chuntian was already in tears, "I held on for ten minutes, and there's still no sign of damage..."

"We made it!"

The loudspeaker immediately broadcast the news.

Even with the steel door tightly closed, Lao Jiang could still hear the cheers from his colleagues outside.

The dog happily pulled out a white paper package. It hadn't been easy; finally, it could hand over the package.

"There's not much, just two sticks. Shall we each have a puff? I watched them smoke them when we were hunting bald eagles, and I've been wanting to try them for ages!"

Old Jiang took the cigar. "The kid you were talking about earlier?"

No, you misheard!
