"Zhang Yong, my dad's convoy has had an accident! All three Dongfeng trucks are stuck on that dirt road in Tongxian County, and one of them is even stuck in a ditch!"

"The foreign experts we hired said it's beyond saving and should be scrapped! My dad is going crazy!"

"Could you come over here? My dad heard about your driving skills from me and wants you to see if you can get that car out of the ditch!"

Zhang Yong dialed Wei Shuyun's number and heard her anxiously say a lot. He quickly noted down the location and hung up.

Wei Shuyun's father, Wei Dabiao, was a well-known figure among the parents of Chuiyangliu Middle School. In the late 1980s, he went into business and opened a small winery in Tongxian County. It was not large in scale, but the business was doing well.

Three Dongfeng trucks—that should be the entire transportation capacity of the distillery.

Without giving it much thought, Zhang Yong told Li Guilan and left.

......

After waiting at the bus stop for ten minutes, Wei Shuyun arrived on a 28-inch bicycle with a military flashlight strapped to the back seat and a wrench stuffed in the basket.

"Get in! The bus only comes once an hour, it's too slow, I'll give you a ride!"

Zhang Yong glanced at the large truck, then at Wei Shuyun's height of less than 1.7 meters, and his eyes widened.

"What? You're taking me with you?"

"Enough talk! Get on here!"

Zhang Yong would never be able to bear the shame of having a young girl ride a bicycle with him, so he quickly grabbed the handlebars and had Wei Shuyun sit behind him and give directions.

He stood up and kicked hard, sending the heavy bar wobbling as it hurtled into the night.

On the way, Wei Shuyun managed to explain the situation clearly.

The distillery signed a supply contract with a grain depot in Hebei Province. They must deliver three truckloads of sorghum raw materials today, or they will be fined 2000 yuan per day.

The convoy set off in the morning, and when they reached that dirt road on the outskirts of Tongxian County, all three vehicles stalled one after the other.

Wei Dabiao first borrowed a vehicle to transport some grain, but those were small vehicles, and after half a day of delivery, half of it was still left.

He had no other choice but to spend a lot of money to borrow a technical consultant from a foreign company in Beijing. An American named Smith came with a translator and spent most of the day trying to figure out that the main pump had burned out and had to be scrapped.

"With three cars scrapped, my dad's winery is finished." Wei Shuyun's voice came from behind, the wind scattering half of her words.

Zhang Yong remained silent.

Forty minutes later, the old-fashioned truck turned onto a dirt road.

I could see it from afar.

Three Dongfeng 141 trucks were parked on the side of the road, their headlights long since off, making them look like three-headed mountain gods in the darkness.

The right rear wheel of the last vehicle was stuck in a shallow ditch on the shoulder, the vehicle was tilted, the truck bed was tilted, and many sorghum sacks were crushed under it.

Two kerosene lamps were set up by the roadside, their dim light illuminating a circle of shadows.

Seven or eight workers squatted on the ground smoking, their faces covered in ash and grease.

A middle-aged man in a t-shirt was pacing back and forth in front of the hood of a car, his hair plastered to his forehead with sweat, muttering something under his breath.

Wei Dabiao.

He was in his early forties, with a square face, thick eyebrows, big eyes, and a robust build. He looked like someone who had carried sacks and pedaled tricycles in his younger days.

A little further away, a blond, blue-eyed foreigner leaned against a Santana car, arms crossed, looking very impatient, and was whispering to a translator wearing glasses next to him.

"Dad!" Wei Shuyun propped up the car and pulled Zhang Yong over.

Wei Dabiao turned around, first glancing at his daughter, then at Zhang Yong.

He looked me up and down for two seconds.

He's just a greenhorn, but we have to try anything, even if it seems hopeless.

He grabbed Zhang Yong's arm and pulled him towards the car stuck in the ditch. "Zhang, I heard from Lao Chen that you're a pretty good driver, you can even do a two-wheel turn! Look, this car's stuck in the ditch, can you figure out a way to get it out?"

He pinned all his hopes on Zhang Yong's driving skills, which were comparable to those of a special forces driver.

After all, even foreign experts have given up on the engine.

If they can tow the stuck car out, they can reduce the amount of compensation they have to pay.

Zhang Yong shook his head, thinking that if the engine was broken, even the most skilled driver couldn't fix it.

However, he still took the military flashlight and walked around the three vehicles.

The first car had its hood open, and the spark plugs had been replaced—brand new, but useless.

The second car had the same symptoms.

The third car, the one stuck in the ditch, was tilted, but the hood was open, and there were obvious signs that the parts inside had been tampered with.

Three vehicles, from the same batch, developed problems on the same day, and exhibited the same symptoms.

This is not an isolated malfunction.

Fortunately, he spent some time at the bookstore during the day and, with his Lv.5 driving level, managed to understand some of the controls.

Let's check it all out according to the instructions in the book first!

Zhang Yong squatted down and shone his flashlight on the exhaust pipe of the first car.

There was a layer of black, greasy residue on the inside of the pipe wall. When you rub it with your finger, it becomes sticky and smelly.

He then opened the oil cap and pulled out the dipstick.

The oil color on the dipstick is wrong. Normal engine oil should be amber or dark brown, but this is blackish-gray and the viscosity is obviously insufficient. When you rub it between your fingers, there is almost no sticky residue.

"Uncle Wei, when was the last time this car was serviced? Where did you buy the engine oil?"

Wei Dabiao was taken aback, not expecting Zhang Yong to ask about engine oil.

"I just had my car serviced last month! The engine oil was bought from the Tongxian auto parts market, twelve yuan a can!"

A bucket costs twelve yuan.

Zhang Yong felt more confident.

A can of genuine engine oil from 1990 would cost at least 30 yuan. The engine oil you buy for 12 yuan a can is all mixed with waste oil.

Zhang Yong rolled over and climbed onto the hood of the first car.

"Hey, kid, be careful not to fall!" Wei Dabiao tried to pull him up.

Zhang Yong was already lying on top of the engine, his palms pressed against the scorching hot cylinder head.

"Hey! Kid, that's not for you to touch!" The translator walked over from the Santana, pushed up his glasses, and spoke with perfect poise.

"Mr. Smith said the main pump of this engine has burned out. If you tamper with it and damage the seals, the compensation will be settled in US dollars."

Zhang Yong ignored him.

He carefully placed his palm on the metal surface, meticulously sensing the condition of every component inside the machine.

If the main pump burns out, the coolant temperature will rise abnormally, causing the water tank to boil.

The water tanks of all three vehicles are functioning normally.

Zhang Yong closed his eyes, thinking about the car knowledge he had read in the bookstore during the day, and compared the theory with the tactile sensation from his palm.

A sense of sluggishness.

The real problem might be with the valves.

The large amount of sludge and carbon deposits produced by inferior engine oil accumulate near the valve spring seats, causing the spring travel to be obstructed.

Engine shutdown and cooling causes sludge to solidify.

The spring was thus stuck in its original position.

If the valves cannot open, the intake and exhaust are cut off, and the engine will naturally fail to start.

This situation can be fixed.

The spring was simply stuck.

Just as Zhang Yong's fingers were tracing the edge of the cylinder head, a prompt popped up on the panel in his mind.

[Ding! Deep mechanical interaction behavior detected. Evaluating skill unlock conditions...]

[Theoretical knowledge required: Satisfied (basic automotive structure)]

[Practice Trigger Conditions: Already Met (Driving Lv.5 Mechanical Perception + Physical Contact Diagnosis)]

[Auto repair skill progress loading...]

[Auto Repair Lv.0 - Entry Level: 10%]

The skill has been successfully unlocked, and you can now see your progress in getting started.

Zhang Yong breathed a sigh of relief, not expecting such a pleasant surprise.

The skill level isn't high enough to fit into the AFK slot yet, but it's better than the blind men and the elephant wall.

He rolled off the hood and landed, looked around, and finally his gaze fell on Wei Shuyun's hair.

"Can I borrow the wire hair clip on your head?"

"I need my car repaired."
