A nation's industrial development begins with junior engineers.

Jiangxia is certainly an option; you should know that this water spray system has been standard equipment on trucks for a long time.

However, to install them all, we still need to submit a report to higher authorities.

Although the chief engineer of the technical department signed the project approval form, it would still take a lot of materials and manpower to get all twenty-odd vehicles of a transportation team on board.

Furthermore, isn't it a bit inappropriate to mount the water tank on the front of the vehicle?

It's fine when it's full of water, but after it's half empty, the water tank makes a loud clanging sound whenever you brake.

On one occasion, during a sudden stop at high speed, water from the radiator splashed out.

Water hammer effect!

Thinking of this, Jiang Xia quickly climbed onto the front of the truck.

They carefully inspected the water tank.

Sure enough, the water tank, made of thin sheet metal, had been slightly bulged out at the front of the car.

Look at the bolts below; they've started to loosen.

Even the sheet metal on the roof was torn open. Luckily, the roof material used in modern vehicles is sturdy; if it were sheet metal from later generations, the radiator would probably have been blown off long ago.

Damn! Luckily we discovered it in time, otherwise what was meant to save our lives could have turned into something deadly!

Jiang Xia couldn't imagine the scene of the water tank rolling off after a sudden stop.

Mechanical design is not something you can just do on a whim!

After jumping off the truck, Jiang Xia didn't try to cover up the problems he had discovered; instead, he explained everything clearly to the truck drivers.

"In conclusion, this water spraying system still needs improvement!" Jiang Xia said with a hint of guilt as she handed the toothbrush to Liu Jun.

Wang Tiezhu walked up and patted Jiang Xia on the shoulder: "It's alright, nothing is ever perfect on the first try! Besides, these are just minor issues. Before each trip, we just add a few extra steps and look up at the roof of the truck, and it's fine!"

"Yes, yes, it's broken. We can just add another piece of rubber on top, right?"

The drivers nearby also gathered around, chattering amongst themselves.

Jiangxia was amused, and a few more cigarettes were released.

"What the experts say makes a lot of sense, much better than what I, a complete novice, have to say! I think we should sit down and discuss how to improve this sprinkler system, shall we?"

"Oh dear, Hua Zi! Engineer Jiang is really going to be ripped off this time, with toothbrushes and Hua Zi involved. Is he trying to kill himself?"

"Hey, Old Wang, you're joking. With your job, if you wanted to smoke, you'd smoke every day, wouldn't you?"

Old Wang laughed heartily.

That's not all. Old Wang's monthly salary is only 78 yuan, and that's not even the biggest part of it.

When driving a sports car, even just giving a few rides to a few people along the way can earn you several cents. If you happen to encounter someone who wants to sell goods, it's even more lucrative.

The saying goes, "When the wheel turns, gold is worth a fortune."

If you were to ask Lao Wang and Jiang Xia to switch positions, he would definitely be unhappy.

"That's different! This was handed to me by a college graduate from our factory! And he's an engineer!"

"I can't bear to smoke this cigarette; I want my youngest son to bask in your wealth!"

As he spoke, he offered cigarettes to his fellow workers, but then put the one Jiang Xia handed him into his inner bag.

Another heated discussion ensued.

Finally, it was decided to move the water tank from the roof to the bottom of the truck, next to the large fuel tank, and weld it directly to the main beam.

The water supply system pipelines were also redesigned to be as close as possible to the truck bed without obstructing the truck's passage.

Several springs were added to the valve to ensure smooth operation, while the opening and closing degree of the valve was controlled by the change in the tension of the wire.

In other words, the more force you apply, the more water you can produce.

In this way, the simplified water-spraying cooling system is nearly perfected.

Jiang Xia spent a lot of time erasing and revising the design drawings, and finally asked all the drivers present to sign them.

The conclusion reads: "The above individuals are all users and improvers of the water-cooling system! The wisdom of the working people is boundless; long live the great workers!"

After Wang Tiezhu, who only had a junior high school education, read these words aloud, one by one.

Everyone's face turned red.

Jiang Xia also mentioned that the drawings should be archived and submitted to the First Ministry of Machine Building.

When other departments needed to use the drawings, their names would be displayed to the users, and the entire transport team fell silent.

Several experienced workers were huddled together, not even knowing when Jiang Xia had left.

Old Wang's fingers were burning from the hot liquor in his hand, but he didn't budge.

Wang Tiezhu held the teacup but didn't drink a drop of water, staring blankly into the distance.

Liu Jun stroked his toothbrush with both hands, muttering something like "I'm famous now, bringing glory to my ancestors."

Old Wang suddenly yelled and flung away the cigarette butt in his hand.

This shout seemed to wake everyone from their dreams.

The crowd burst into laughter again. Old Wang waved his hand in annoyance and put his burned finger in his mouth to suck on it.

"Oh, what a pity. I think I didn't write my name well just now. Could you rewrite it? Engineer Jiang, is that alright? Hey, where is everyone?"

Startled awake, Wang Tiezhu said irritably, "Everyone else left long ago. Besides, your handwriting is so messy, it'll be the same no matter how much you write!"

"Hey, class monitor. Why are you letting him go? He did us such a big favor, he deserves at least a drink or two!"

Wang Tiezhu picked up his teacup and took a sip of water.

"There's plenty of time! We'll take it slow. But shouldn't you be thanking me more?"

"Back when you first arrived, you were such a mess, I don't even want to talk about it!"

Old Wang chuckled ingratiatingly and quickly handed him a cigarette.

"Why don't you be the class monitor? I can't compare, I can't compare!"

Wang Tiezhu snorted twice, his nose practically pointing to the sky.

Liu Jun came over and lit the fire for his master.

“Master, please don’t blame us for how we acted back then. Look at those two college students who interned with Jiang Xia, what kind of idiots were they? They didn’t even know what a carburetor looked like, yet they were pointing and gesturing wildly, ugh!”

At that time, the steel rolling mill assigned three college students for internships. Jiang Xia went to the workshop first, another went directly to the logistics department, and the third came to the transportation team.

Apart from Jiangxia, the other two both showed off their power quite a bit, making the employees below them extremely disgusted.

Jiangxia was caught in the crossfire and it took him a lot of effort to change people's opinion of him.

"Hmph, ignore them, they're not on our side!"

"Alright, pack up and get ready to leave work. Tomorrow we'll fix the sprinkler system properly! It's a matter of life and death!"

Everyone responded in unison.

After saying goodbye to the transport team, Jiang Xia prepared to return to his office to finish the report on the water sprinkler system.

As I walked, I kept thinking about whether I should take out the synchronizer and seat belt.

But none of them are easy to handle. Seat belts may seem simple, but they actually consist of a series of components such as retractors, pretensioners, and load limiters.

Putting aside everything else, we simply can't make the spring in the retractor with our current technology.

The same applies to synchronizers, since Jiangxia is located in a steel rolling mill and has no machining capabilities.

Eh, forget it.

Why get so hung up on the details? If you can't get a fully-equipped version, go for a basic one.

As long as I can survive. After all, a car accident in this day and age is definitely a workplace injury.

If it's a work injury, the factory will support you.

These days, capitalists don't let you play the dismissal game anymore.

On the way, Jiang Xia deliberately took a detour to visit Uncle Jiang in Workshop 2, or rather, his nephew Jiang.

Just then, the bell rang to signal the end of the workday, and the two agreed to have dinner together at the second canteen that evening.
