A nation's industrial development begins with junior engineers.

Train 131 charged forward fiercely, like a ferocious beast, but its movements were strangely gentle, as if a mother were embracing her child, gently catching the sliding carriage.

The child was a bit heavy, causing 131 to slowly back away.

At this moment, the small red-painted cannons on both sides of the carriage started moving.

One unit.

Two...

Like a leaping flame, a single spark can start a prairie fire!

As the sound of boulders rolling down ahead continued, the train moved forward instead of backward, slowly climbing towards the top of the slope.

Rat-a-tat-tat!!

The sound of the eight small cannons drowned out the panting of 131, and in an instant, a bunch of heads appeared at the windows on both sides of the carriage.

Some of the bolder ones even opened their windows and waved to Jiang Xia and the others.

"come on!"

"come on!"

Presumably, the train attendant had already told them what had just happened, and their initial anxiety was greatly relieved as the train slowly moved forward.

A strong wind blew by, followed by another shower of stones.

"Ouch! Watch out!"

Suddenly, the people in the carriage gasped in surprise.

Jiang Xia looked up and saw a dark shadow flash past his eyes, landing heavily on Xiao Gangpao's head.

The once beautiful headlights were instantly shattered.

Jiang Xia was startled, but the small steel cannon, which was still climbing, dispelled his concerns.

"Well done, you're truly my son!"

A strong wind picked up again, and a pattering sound came from above Jiang Xia's head.

He instinctively shrank back, thankfully wearing a tank helmet, which saved his clever head!

He faintly heard a muffled groan, but the wind kept him from looking, so he could only keep driving forward with his neck hunched.

The train continued its journey and finally reached the top of the hill.

The front of the FD heavy truck was already visible; it was panting heavily, continuing to push forward while carrying half a boulder. There seemed to be someone calling out to something from behind the truck.

Jiang Xia squinted and scrutinized him closely.

Depend on!

I can't see clearly, but my night blindness was cured, so why has it regressed?

With a thud, the train carriage suddenly lurched to the right, the force of which sent Little Cannon staggering back a few steps.

What happened?

Oops... Could there be something wrong with the tracks?

Jiang Xia, who had no idea about train operations, was at a loss. Should he continue to delay or stop and wait?

Looking back, a figure came running up from behind against the strong wind.

Jiang Yuanchao?

He first said something to Daozi behind Jiang Xia, and then rushed towards Jiang Xia.

"Keep going! Don't stop!"

The words had barely left his mouth when they were scattered by the strong wind.

Fortunately, Jiang Xia heard the word "continue." He gritted his teeth, stepped on the gas, and the previously slack steel cable straightened again.

Jiang Yuanchao rushed to Jiang Xia's side and shouted, "Don't stop! Hold on! No matter how much it shakes, don't stop! Uncle Zheng said so!"

Jiangxia nodded vigorously.

Seeing that Jiang Xia understood, Jiang Yuanchao immediately ran towards the FD car, which was still struggling against half of the boulder.

Crimson bloodstains were imprinted on the snow on both sides of the road as Jiang Yuanchao ran, and were immediately covered by new snowflakes when the wind blew.

Stepping onto the locomotive, Jiang Yuanchao disregarded manners and grabbed Hu Muyuan by the collar, shouting in his ear, "The connecting bolt on the left side of the rail is loose, and the sleepers under the rail have shifted. Uncle Zheng said your locomotive must be connected to the rear carriage immediately!"

Hu Muyuan leaned out of the driver's window, looking at the half-stone that clung to him like a maggot, and felt a surge of hatred.

"Add more coal! Add more coal! There's a small bend ahead, let's get this bird out of there!"

"Yuanchao, go tell the flight attendant to have all the passengers move to the right!"

Jiang Yuanchao immediately hung from the railing of the driver's cabin, took out a long-handled socket from the toolbox, and jumped down when he found an opportunity.

As soon as my feet touched the ground, I instinctively tried to run a few steps forward.

The excruciating pain in his foot made his legs buckle, and he fell flat on his face, rolling away quite a distance.

He gritted his teeth, got up, ignoring the blood on his forehead, grabbed the railing of the carriage behind him, and stepped into the carriage.

"Taskmaster! Quickly get all the passengers to gather in the right-hand carriage!"

Several flight attendants heard this and immediately began working without waiting for instructions from the chief flight attendant.

One of the passengers, seeing Jiang Yuanchao covered in blood, took out a towel and tried to wrap it up for him.

Jiang Yuanchao shook his head, smiled, and jumped off the train again.

Avoiding the traction steel cables, I jogged all the way to the loose section of the rail.

The originally smooth rail had a joint where it bulged up by one centimeter. When the train wheels hit the bulge, it caused the train to wobble.

One centimeter! Just one centimeter!

Clang clang~~ Clang clang~~

Lying on the bottom of the roadbed, Jiang Yuanchao found the bolt that had already slipped.

He lay half-reclined close to the ground, and before the next wheel arrived, he stretched out the socket and twisted it hard a few times.

As the wheels passed, Jiang Yuanchao didn't have time to let go. A tremendous force came along the rail, and the bolt that had just been tightened slid outwards again. At the same time, the sleeve twisted a few times in Jiang Yuanchao's hand like a snake, as if trying to break free from his control.

"Ah~~"

He screamed in agony as blood gushed from his tiger's mouth.

Before I could think any further, the next wheel was almost there.

Well done, Jiang Yuanchao! He quickly turned the sleeve again, and the bolt was tightened on a second time.

This time, the bolt didn't slip...

Jiang Yuanchao pressed his body firmly against the sleeve.

A wheel,

Two wheels,

……

"Hehe, it's just 14 carriages and only 28 wheels in total. Compared to the senior, this is nothing!"

"Jiang Yuanchao, you can do it!"

The sleeve writhed unwillingly beneath Jiang Yuanchao, but he held it down firmly.

Another powerful impact struck, and Jiang Yuanchao's vision went black. Intense pain spread from his elbow to his abdomen, and a warm liquid flowed from his mouth and nose.

For some reason, I suddenly remembered the question the old man asked me when I first arrived in this Gobi Desert, and how I answered it.

Oh, right, my answer was: I want to go to the places where the motherland needs me most.

Would you say this is the place where it is "most needed"?

A strong wind blew by, stirring up the crimson blood that Jiang Yuanchao had dripped, which smeared onto the round badge in the carriage.

.........

When Jiang Yuanchao woke up, he found himself in an unfamiliar room, where a stranger with a buzz cut was fiddling with his hands.

"Awake? Oh! Flight attendant, Yuanchao is awake!"

Jiang Yuanchao recognized the voice; it belonged to a train attendant from the K3 train. She had passed by her rest area earlier and even tossed her a large loaf of bread.

I tried to sit up by supporting myself with my hands.

The man with the crew cut stopped him, saying, "Your forearm is broken into three pieces. Just stay put. It's already bandaged up. Don't strain yourself!"

"Train~"

"The car is fine, we'll be at Erenhot Station in half an hour!"

As he spoke, the man with the crew cut helped Jiang Yuanchao up, patted him on the shoulder, and handed him over to the flight attendant who had rushed over.

He then stepped back a few paces to the back of the crowd, looked around, and, finding no one paying attention to him, opened the door to a private room and slipped inside.

The private room, which was originally designed to accommodate four people, was packed with seven or eight people.

Our classmate Xiao Jiang is among them.

At that moment, he was kneading a lump of flour-like substance.

"You little brat, is this what you called something that could help us?"

Watching Jiang Xia, who resembled a pastry chef, twitching the corner of his mouth with a knife, I couldn't resist gently tapping Jiang Xia's bulging lip.

"Of course! If you want to get the stuff without alerting those old Russians, this is the best option."

"Assuming that thing is actually there!"
