A nation's industrial development begins with junior engineers.

After opening the large box, the man in the white coat quickly installed various seemingly mysterious instruments in different corners of the flatbed truck.

Each instrument had a long tail extending from it. They all eventually converged on his large box.

"set off!"

Eight small steel cannons pulled the flatbed truck slowly forward.

The man sat directly on the cart, frowning as he looked at some instruments in the box.

"Hey, this table is for balance, what's that table again?"

"Tsk, I told you I couldn't do it, but they still insisted on sending me. What do I, a roughneck, know?"

The probing gaze extended outwards, looking at the ahoge (cowlick) swaying beside the transport vehicle.

He reached out and took the walkie-talkie from the soldier next to him.

"Hey, you stray dog, barking!"

A whooshing sound came from the walkie-talkie: "Speak!"

"Uh... this country bumpkin can't understand these clock faces. Could someone please take a look?"

"Who?"

"Lao Jiang."

There was a pause on the other end of the line: "Which Old Jiang?"

"Yeah, the one where you compared your son to someone else's, and ended up getting blown to bits."

"Wait!"

After a while, instead of the test results, a scolding came first: "I just trained you this morning, and you can't understand it this afternoon? Are you useless?! If only we had someone else..."

"Damn it! Yesterday I got 48 rings in target practice, while someone else only got 40. Isn't that terrible? Besides, this morning the numbers were real numbers, but now it's just a tiny dot bobbing up and down. I can't understand a thing!"

There was a sudden silence on the other end, and then a sound came back after a while.

"Request denied. Lao Jiang has entered a top-secret area."

Hearing this, "Tu Gou" frowned. "Don't mess around! Even just taking a look from afar would be fine!"

"What are you thinking! Yesterday, the external factory sent an urgent batch of goods. The entire R&D team went in. As for you, don't try to do something good that turns out badly!"

"Tu Gou" sighed: "I understand. But I really don't understand. The dial doesn't display numbers, it's just dots that go around in circles, and then it turns into lines. I don't get it! Little Jiang is here, his internal level is much higher than mine!"

"Wait."

After a while, a voice came through the microphone: "Confidentiality authorization, temporary 250, level three. Give your badge to Comrade Xiao Jiang."

"understand!"

"No more nonsense! Unless you want him to stay here until he's all old and gray!"

"groove……"

After putting down the microphone, the stray dog ​​used his nail clippers to vigorously rub the whiskers on his chin.

"Comrade Xiao Jiang, come here and help me check the parameters!"

Jiang Xia had been examining the transport vehicle for a while. He hadn't looked closely at first, but now that it was moving, he noticed that the front and back of the cart were raised, while the middle was lower, making it look like a gold ingot.

Although eight small steel cannons were used to pull it, it was always in low gear, and the speed was so fast that even an old man taking a walk could keep up with it.

Looking at the sensors all over the vehicle, it's clearly a transport vehicle for the Sky Monkey. Was it dragged out for an experiment? To test the coordination between the small cannon and the transport vehicle?

"Can I take a look at the structure? You measured swaying and bumpiness, but is there any flatness?"

"Look around as you like, but only this car." Tu Gou chuckled as he listened to Jiang Xia's use of technical jargon.

Jiang Xia immediately lay down and looked over.

Wow, there are some capable people: the independent suspension with air springs and all-wheel steering are all there, but the braking system is still a bit rough, it's drum brakes.

Hmm, should we add multi-axle group steering? That would seem to increase the range of motion.

Replace the brakes with air pumps; that should make the braking smoother.

Jiang Xia didn't dare turn on his own scanner and made a quick assessment based solely on his experience.

After Tu Gou finished reading, he jumped off the carriage, took the crimson stain from his chest, and pinned it to Jiang Xia.

Jiang Xia looked him over and thought, "General Li is really not being polite. He's already putting his design into practice. I just don't know when he came up with it."

"Don't take this off, keep it with you! Come on, let's go up! I can't understand that tangled thread!"

The dog crouched down and lifted Jiangxia onto the train carriage.

Jiang Xia rolled over to the large box and then sat up.

"Wow, that's impressive! They've integrated the oscilloscope into the box. How do they power it?"

I tried to lift the box, but goodness, I couldn't.

It probably weighs over a hundred pounds; it uses a storage battery underneath.

"You can carry that around like that?" Jiang Xia looked at the stray dog's arm for a moment, then compared it to his own. "They're about the same size, where does it get so much strength?"

Jiangxia moved a few switches next to the screen, and the waveform on the small screen changed accordingly. Fortunately, it was somewhat similar to the same instrument in later generations, so he could manage it!

Hmm, no, there's no waveform playback. The waveform is displayed in real time, but there's no recording function.

We can't waste any more time!

Looking at the waveform that was shaking up and down, Jiang Xia got into the zone and took out his sketchbook from his oversized shoulder bag.

I draw, I record, I never stop.

The transport vehicle moved slowly forward, passing through a residential area for family members.

The buildings are all made of red brick and tile, and scattered in the same way, but the tallest of these buildings is only three stories high. Small trees are planted in front of and behind the buildings. Some of the faster-growing trees have already reached the second floor.

Along the road where the transport vehicles were traveling, some soldiers in khaki uniforms were digging holes. Not far from them were rows of saplings waiting to be planted.

Old Wang and Tu Gou sat side by side in front of Jiang Xia, shielding him from the wind that had started to blow at some unknown time.

"Hey, what's Beijing like now?"

"It's not like that yet, but they've been dismantling the city gate towers recently."

"Still demolishing? It was already demolishing when we left, how far have they gotten now?"

"The outer city walls and gate towers have all been demolished, and now they're working on the inner city."

"so fast!"

"How many years?"

"7."

The two ended their conversation, and Wang Kui put his arm around the dog's shoulder and looked at the sunset in the distance.

The communications soldier silently turned off his microphone, which had been on all the time, and sat down next to Jiang Xia on his left.

A westerly wind is blowing.

Jiang Xia impatiently wiped the sand off the screen. "Speed ​​up! The curve is almost smooth, and we've noted down a few key points. Let's see how it performs at speed 2. If we keep swaying like this, sand will get into the oscilloscope!"

"The small cannons are numbered from left to right. 1, 3, 5, and 7 form one group, and 2, 4, 6, and 8 form the second group. The first group moves forward, and the second group follows after shifting gears!"

"Hurry up!"

The dog reacted quickly, standing up and blowing the whistle hanging from its collar.

When the communications soldier saw his comrade turn around, he took out a signal flag and began to demonstrate it meticulously.

The west wind grew stronger, stirring up sand and dust. Seeing that things were not going well, Wang Kui took out a flashlight from his bag and shone it directly on the flag.

The blinding light pierced through the dim yellow light and shone on the two flags.

The red is dazzling, and the green is delicate and beautiful.

Let's see whether the westerly wind or the easterly wind is stronger!
