But, as the old saying goes, seeing isn't always believing!
If problems could be spotted with just a pair of eyes, Da Xian would have collapsed years ago!
Ye Yun extended a finger, wiped beneath a spark plug, and then sniffed the residue.
Beyond the scent of the 98 octane gasoline burning in the engine, Ye Yun detected a distinct aroma.
This scent was simply the smell of plastic.
The other three spark plugs had no such smell, only one did.
He believed that if this car were driven on the highway for three to five thousand kilometers.
This scent, under the high temperature, would surely evaporate and dissipate quickly. Da Feng Novel Network.
But now, the scent was still present!
It made sense. Normal used car dealers would practically drain the fuel from the car.
How could they possibly afford to fill it up and then drive it three to five thousand kilometers on the highway?
Besides, for sports cars, mileage significantly impacts price.
An extra three to five thousand kilometers could potentially drop the price by tens of thousands.
Therefore, they would naturally not drive it around on the highway.
The scent emanating was the distinct smell of plastic from new components.
For a seven-year-old car from 2014, the presence of plastic from new parts was very suspicious.
Therefore, upon smelling the scent on the spark plug, Ye Yun.
He immediately knew something near the spark plug had been replaced.
More precisely, it was an item related to the spark plug that emitted the plastic odor.
The scope of possibilities was greatly narrowed.
Ye Yun's gaze shifted to the engine of the Audi R8.
Since a part of the engine had been tampered with, this engine must have a problem!
And it had been disassembled, though the method of disassembly was so skillful that ordinary people couldn't tell.
Understanding the key, Ye Yun put down the flashlight and screwdriver, placing one hand on the engine block and the other carefully searching various parts of the engine.
Under the camera, Ye Yun's movements were slow and deliberate, even closing his eyes to fully concentrate.
Seeing Ye Yun's current state, Da Xian and Wang Bing both felt a jolt of unease.
This guy...
He shouldn't find anything, right?
He only worked on the spark plugs, and all of them were dealt with, so there shouldn't be any traces of replacement, right?
However, Ye Yun didn't spend too long touching the engine.
Soon, he reached the spark plug area of the engine.
Then, he stopped.
As a top graduate of medical school, Ye Yun's finger sensitivity was incredibly high, to the point where he could peel a raw egg.
Such high sensitivity naturally allowed him to feel details imperceptible to others.
Now, Ye Yun clearly knew where the problem lay.
Indeed, the master craftsman under Da Xian's employ had reassembled the engine with such incredible skill that it looked flawless even after disassembly.
But he was still human. No matter how meticulous he was, he couldn't achieve a perfect restoration.
It was simple: even a mended broken mirror would still bear its cracks.
Where the engine components joined, the master craftsman had reinstalled them with extremely skillful methods.
To ensure a perfect restoration, they had even sourced original factory nuts.
The problem lay with the nuts!
Every factory-produced nut had the manufacturing date engraved by an automatic machine at crucial connection points.
And the master craftsman, naturally, wouldn't overlook such details, and had dealt with them.
But Ye Yun still found a discrepancy.
Ye Yun noticed that one of the spark plug nuts, compared to the other three, had a subtle difference in the height of the last digit of its date.
This subtle difference required a vernier caliper to distinguish.
Even if an ordinary person felt it, they wouldn't notice anything unusual.
It was like playing Mahjong; someone who played often could tell by touch whether a tile was "Red Dragon" or "White Board."
But someone who never played, no matter how hard they tried, couldn't feel the difference.
This minute difference made Ye Yun certain that the other party had tampered with this area!
Batch-produced nuts wouldn't have such a noticeable flaw.
Combined with the peculiar smell on the spark plug, it further confirmed Ye Yun's suspicion.
This Audi R8, just like in his past life, had significant tampering with its engine.
And Da Xian had reassembled the engine using original factory parts.
Unfortunately, even the most skilled eventually slip up; a small oversight, a mistake that even an expert might not detect, was ultimately found by Ye Yun.
Since he had found the problem, Ye Yun saw no point in wasting more time with Da Xian.
It was happening live, which was enough to ruin him and send him back to his previous life's path.
The only difference was that this time it was a few months earlier than in his past life.
After washing his hands, Ye Yun dried his palms with a paper towel and then closed the hood of the R8.
Lin Shiyou and the other person saw Ye Yun's actions and knew.
Brother Ye had found the problem!
Their excitement was even greater than if they had gone out to find young models!
Brother Ye...
Brother Ye had once again exposed that unlucky fellow Da Xian!
Then, they quickly looked at Da Xian, ready to mock him.
However, Ye Yun spoke first, questioning him.
"You just said this car was a premium car, original paint and all, correct?"
"You checked it yourself just now, isn't what I'm saying the truth?" Da Xian shot back through gritted teeth.
"You know yourself if it's the truth," Ye Yun sneered, then looked at Wang Bing, "You mentioned earlier a method to check parts and their production dates. Would you dare to say it again in front of the livestream audience?"
"Before... before April 2014!"
With so many netizens watching, Wang Bing couldn't back down.
"Before April 2014?"
Ye Yun couldn't help but burst into laughter, "Good, very good! Since you say it's before April 2014, then please do me a favor and remove the third and fourth nuts on the spark plugs!"
As he spoke, Ye Yun tossed the flashlight and screwdriver over, then looked towards the camera broadcasting Da Xian's livestream.
"Everyone, let's see what date the nuts Master Wang removes will show!"
"Master Wang, please, don't keep the brothers in the livestream waiting."
Ye Yun gestured to Wang Bing again.
Wang Bing, startled by Ye Yun, turned pale and broke out in a cold sweat, almost losing his balance.
"Master Wang, why are you unsteady? Are you guilty?" Ye Yun taunted.
"Remove them!" Da Xian said coldly, his face like ice.
Even now, he still didn't believe Ye Yun could find a fault in the engine.
After all, Old Zhao had never been exposed in all these years!
Even insiders couldn't see it; this Ye Yun clearly looked like an amateur. Could he possibly find this?
Hearing Da Xian's command, Wang Bing approached trembling. After some fumbling, he quickly removed two nuts from the spark plug area of the engine.
Under Ye Yun's direction, these two nuts were fully displayed on camera.
Alongside them were two vernier calipers!
When measuring the scales on both sides, there was a clear difference in the numerical values.
Da Xian's livestream exploded...
