In the 90s, you could acquire max-level skills every 14 days.

As soon as Zhang Yong finished speaking, the courtyard fell silent.

The four apprentices looked at each other, one of them scratching his forehead, looking a little guilty.

Liu Decai's face turned bright red.

"You're talking nonsense! You're barely grown up, and you dare to yell at your grandpa!"

He kicked the small table in front of him away, preparing to go up and give Zhang Yong two punches.

"What's the rush?"

"Snap—"

As soon as Zhang Defa finished speaking, he pulled out an oversized open-end wrench from his canvas tool bag.

This wrench is nearly two feet long, made of pure steel, and weighs at least two and a half pounds.

He tapped the wrench twice in his left palm.

Then he stood directly behind Zhang Yong, firmly planted his lower body.

This is an old habit formed in the military; it can protect the rear and also allow for movement at any time.

Zhang Defa raised the wrench with one hand, pointed it at Liu Decai, and looked calmly.

What were you trying to do just now?

The voice was very loud; you could tell he was a trained fighter.

The four young men were just putting on an act to scare the girls, but unexpectedly, two men showed up, one of whom was carrying a weapon.

The young man in front quickly took two steps forward and spoke close to Liu Decai.

"Second Uncle, this person looks familiar! Let's not waste our time and ask him first."

Liu Decai's gaze swept back and forth between Zhang Defa and the wrench twice before he loosened his fist.

"Who exactly are you?" His tone was noticeably more polite.

"This is my repair shop. What do you mean by this? You're just dismantling my place without saying a word. That's not very ethical."

Zhang Yong reached into his pocket and pulled out a red hard-cover ID card.

Turn it over.

It has the Chaoyang District Traffic Police Corps Special Driving Qualification Certificate printed on it, and contains the name and photo, as well as an official seal.

"I am a special driver from Chaoyang District." Zhang Yong showed his credentials to Liu Decai.

"This is my dad, a veteran driver at the Beijing Cotton Mill. We're both just ordinary workers."

"You replaced old roof tiles with new ones, used the wrong type of cylinder head bolts, and then told the girl you wanted a major overhaul costing three thousand yuan."

"If you think this is something that can be brought up publicly, we can call the traffic management department and the petrochemical research institute to come and take a look. We can also test what kind of engine oil you're using in your factory."

Liu Decai got angry and was about to start cursing again!

"Who do you think you are! Don't you know I'm above you...?"

"Oh, Zhang Yong! It's Zhang Yong!"

The man who had just called Liu Decai "Second Uncle" finally realized what was happening. He stared at Zhang Yong's name on the driver's license, his face full of surprise.

He pushed away his second uncle, who was still cursing, and tightly grasped Zhang Yong's hand!

"Brother Yong! I'm Liu Sanqiang, a year younger than you!"

"The school said you had a speech to give and told us to go, but I was at home... I didn't go..."

"But I read your magazine!"

"Second Uncle! This is the one I showed you last time, the author! From our school!"

Liu Decai was still angry and didn't care about anything else.

"I don't care what he wrote! I've been repairing cars for twenty years! Do you think I'm afraid of some kid!"

Liu Sanqiang also became anxious.

"It's that one about a great nation, praising our workers. You read it three times yesterday! They'll write a piece to criticize you! They'll make you lose face in Beijing!"

Liu Decai finally realized what was happening and was completely dumbfounded.

"What? Him? Isn't he the driver?"

Zhang Yong couldn't be bothered with the two of them.

He then began to explore the number one car.

[Automotive Repair Level 2 Perception Feedback: Cylinder wall honing marks are still present, and the wear is within the standard range.]

There are coolant leaks on the cylinder head gasket sealing surface, indicating the gasket is blown, but the cylinder block and cylinder head themselves are not deformed. No cylinder boring or cylinder liner replacement is needed. Replacing the cylinder head gasket is sufficient.

Zhang Yong stood up.

"This car doesn't need major repairs."

He took his wrench from the toolbox Zhang Defa handed him, and then pulled out a new gasket—he had asked Old Zhao to find it in the cotton mill warehouse before he left, and it was the same size.

"The head gasket is blown, just replace it. The crankshaft bearings aren't badly worn, I don't need your old ones, just put the originals back in, and it should be fine for another 10,000 kilometers."

After Zhang Yong finished speaking, he didn't look at Liu Decai again and immediately rolled up his sleeves and got to work.

Zhang Defa stood beside him, handing him tools: wrenches, sockets, ratchet handles—he handed him whatever Zhang Yong said.

The father and son worked together seamlessly. Although Zhang Defa wasn't a professional mechanic, his twenty years of experience as a long-distance driver meant he had all the basic skills for changing tires and connecting wires, so handing over tools and adjusting parts was a piece of cake for him.

The people in the courtyard didn't leave.

Liu Decai stood three meters away, his face alternating between pale and flushed, his lips moving a few times but not uttering a single word.

He was actually scared too. Although he had some connections in the traffic management bureau, he didn't know anyone at the petrochemical institute.

If this kid finds out he's using a mix of good and bad oil, he's doomed!

Besides, Zhang Yong's article was really good...

Moreover, after watching for a while, he realized that the young man was incredibly skilled at his work, far superior to his own mentally challenged nephew, Liu Sanqiang, who had skipped school halfway through his studies.

Wei Shuyun stood to the side, clutching her canvas bag, her gaze fixed on Zhang Yong.

Zhang Yong's movements were clean and efficient.

The broken bits in the cylinder head bolt holes were cleaned by tapping twice, the new cylinder head gasket was placed on, the cylinder head was put back in place, and the ten bolts were tightened in diagonal order.

Reconnect the oil pipe, tighten the water pipe clamps, and return the thermostat housing to its original position.

There wasn't a single unnecessary movement throughout the entire process.

Zhang Defa watched in astonishment. Was this really his son? When did he become so skilled? Old Zhao had taught him incredibly well!

The whole thing lasted about ten minutes.

Zhang Yong tightened the last bolt into place, stepped back, bent down, and grabbed the hand crank.

Shake it vigorously three times.

The engine coughed twice, then thump-thump-thump-thump—started up.

A puff of pale gray smoke came out of the exhaust pipe, and after two seconds the smoke dissipated, and the engine sound stabilized.

The idle speed is very stable.

There were no unusual noises, no shaking, and no white smoke.

Wei Shuyun's eyes were bright and sparkling, as if there were tears in them.

Zhang Yong wiped the oil off his hands and turned to look at Liu Decai.

"It's something that can be fixed in ten minutes. The head gasket costs twenty dollars. You quoted three thousand."

"Boss Liu, your business practices are really shady."

Liu Decai's lips twitched twice, and the last bit of confidence on his face crumbled.

He never dreamed of this.

An article writer ruined his plans in just ten minutes.

He originally planned to dismantle all three cars, replace a bunch of old parts with new ones, and keep some original parts for his own use, while also making a profit of three thousand yuan.

It's said that a fitter has eyes, a carpenter has hands, and a scholar's brain is always on the move.

How come these scholars are so cunning, even more so than I am?

"Where's the deposit?" Zhang Yong held out his hand.

"What?"

"Return the 500 yuan deposit paid by Factory Director Wei."
