A nation's industrial development begins with junior engineers.

I didn't have high hopes for this system to begin with, so I figured I'd be happy to have as much stuff as possible.

Jiang Xia returned to his office and finished completing the blueprints.

Before long, Wang Tiezhu from the transport team arrived.

"Haha, Jiang Xia, the water tank is finished! I'm not scheduled to work this afternoon, hehehe!"

Jiang Xia understood: "Uncle Wang, I've just finished drawing the blueprints, shall we go and get started now?"

Wang Tiezhu rubbed his hands together. "That's great! You're really efficient!"

"It's not that I'm pressuring you, it's just that I'm really unsure. I'm getting old, and I'm getting more and more afraid of dying!"

Jiang Xia raised an eyebrow: "How can it be out of fear of death? This is called safety above all else! Strictly control production risks!"

"Hey, if you weren't a college student, those words would sound much better coming from you!"

Wang Tiezhu helped Jiang Xia carry a pile of odds and ends. Jiang Xia casually wrote down his whereabouts on the small blackboard in the office before they headed to the transport team together.

Passing by Workshop 3, groups of two or three steel rolling workers were gathered at the workshop entrance.

The once noisy workshop became somewhat quiet, with only occasional "bang bang bang" knocking sounds.

Interspersed with someone's angry curses.

"What are you repair team doing? It's been so long and you still can't fix it! You're delaying production, I'm going to report you to higher-ups!"

"What are you yelling about! Is it because we didn't fix it properly? It's obviously your fault for operating it incorrectly! Look at the state of the work rollers!"

"You still want to sue? Go ahead and sue! We're going to sue you too! We'll say you deliberately damaged public property!"

Upon hearing that sharp voice, it was clear that it was Ma Weihong.

No wonder Ma Zhendong always drags Sister Wei Hong along when he goes to the workshop; her smooth talk is so satisfying to listen to!

The 300 series... I have such a love-hate relationship with you.

Upon arriving at the transport team, Jiang Xia directed the placement of the thin-sheet welded water tank on top of the truck.

Secure it with a few bolts first.

No problem. When the water tank at the top is filled with water and the valve is opened, the water flows to the brake pads under the influence of gravity to cool them down.

Jiang Xia used a wire to pull the valve directly to the gear shift in the driver's cab.

I tried it twice, and it worked quite smoothly.

Jiang Xia waved his hand and said, "Add water!"

Wang Tiezhu picked up a bucket, climbed onto the roof of the vehicle, and filled the water tank with a splash.

Unfortunately, only the main production workshops in the factory have running water right now, so the transport team has to carry everything by hand.

Open the valve, and a trickle of water appears around the truck's four wheels.

"That's it? Will that even work?"

Looking at the stream of water that resembled a child's urine, Wang Tiezhu began to have doubts about Jiang Xia for the first time.

"Uncle Wang, come and give it a try!"

Jiang Xia jumped out of the driver's seat and called to Wang Tiezhu.

Modern trucks don't have synchronizers; you have to press the clutch twice to shift gears. If you don't do it right, you'll break down immediately.

Given Jiangxia's driving skills with an automatic transmission, he shouldn't embarrass himself by showing off.

"Hey, a synchronizer!"

This seems like something we could try!

Wang Tiezhu scratched his head: "How do I test it? Should I go take a trip around the water plant now?"

"No need, just brake suddenly every few dozen meters. After a few trips like that, the brake drums will be hot. If you feel the brakes are losing power, just pull that wire!"

Then, a squeaking sound came from the open space in front of the transport team.

After braking more than thirty times in a row, Wang Tiezhu shouted, "The brakes are almost gone!"

Jiang Xia cupped his hands into a megaphone: "Pull the wire, open the sluice gate!"

As the valves opened, a cloud of steam billowed from the four brakes.

This time, Wang Tiezhu slowed down the car a little.

With another sudden stop, the truck screeched to a halt, its four tires leaving several dark marks on the concrete.

"It's stopped!"

The drivers who were watching all shouted.

"Let's try again!" Wang Tiezhu was also a little excited, so he floored the accelerator and suddenly increased the speed of the car.

When the speedometer reached 50, Wang Tiezhu slammed on the brakes.

Years of driving experience told him that there was nothing wrong with the brake pedal.

Sure enough, with a screeching sound, the truck slid a short distance and then came to a steady stop.

Wang Tiezhu rubbed the large bump on his head and laughed heartily.

She walked up to Jiang Xia and hugged him tightly, exclaiming, "It was you after all! You really came in handy!"

"Now, I'm not afraid to even go for a run on the water plant, let alone that Broken Soul Cliff!"

The other drivers were also envious, and one by one they climbed into the cab, eager to give it a try.

Jiangxia is perfectly fine with it; it's a good opportunity to collect more experimental data, which can then be submitted with the approval document.

When collecting data, it's essential to follow certain standards.

Wang Tiezhu brought over a large measuring tape and drew several brake lines on the ground.

"Come on, since we're doing an experiment, let's be proper. Let's test the braking distance at different speeds."

"Look how big the difference is between having the sprinkler on and not having it on!"

"We won't let this test go to waste! The one with the shortest braking distance deserves this as a reward!"

Jiang Xia took out the toothbrush he had just pulled out and gestured to everyone.

"Ouch! A chemical toothbrush?"

An experienced craftsman approached and took a closer look.

"really?"

"Hey, Jiang Xia, you're so generous! These chemical toothbrushes are no easy feat!"

Wang Tiezhu walked over and said, "Xia, you don't need to do that. This sprinkler was originally set up for us."

"Isn't it only right that we test it? Using this as a prize is too much!"

Is it valuable? Jiang Xia scratched his head. He had been working in the factory for the past year and hadn't gone out much. He didn't know anything about the market.

Wang Tiezhu's apprentice, Liu Jun, then said, "I went on a blind date a couple of days ago, and the woman wanted this kind of toothbrush and comb."

"Wow, guess how much?"

"Guess my ass! Toothbrushes are 1.2 yuan, brushes are even more expensive at 2.1 yuan, plus a small mirror for 2 yuan. Your sister-in-law was asking me for one the other day!"

An experienced worker interrupted.

"Ha, Lao Wang. You really bought it? You're really willing to spend!"

"What are you buying? It's almost 5 yuan!"

"Hey, Lao Wang. You're short of money? Come back empty-handed, pick up a few people, and you'll have a small mirror."

Old Wang waved his hand dismissively, like shooing away flies: "Money's no problem, but this stuff requires tickets! And they have to be special tickets for specific purposes. Or you could get one of those chemical tickets, two for one item!"

So that's how it is. Back then, plastic was indeed a rare commodity. Unlike later years when plastic bags were everywhere.

Upon hearing this, Liu Jun's eyes darted around. He pushed through the crowd and swiftly climbed into the truck's cab.

"Engineer Jiang, I'm entering this competition! The toothbrush is definitely mine!"

Liu Jun happily started the car, ignoring the jeers and curses from his colleagues below.

He's incredibly accurate in his calculations.

With so many drivers, what if Jiangxia gets enough data and stops testing?

You have to reserve a spot; if you're lucky, you might even get a free toothbrush.

If I collect a few more chemistry tickets and make a complete set, hehehe, then Xiaomei will be mine!

After testing it for an afternoon, all the drivers were convinced that as long as the speed didn't exceed 65 km/h, the truck could stop within 8 meters with the water sprayer on.

"The water sprayer is awesome~~~~"

"Jianggong is awesome~~~~~"

The craftsmen were overjoyed; this was something that could save their lives.

They're all pestering Jiang Xia, demanding that he install one of these things in his car too.
