Reborn in 2011, I am the chief designer of aerospace.

Song Xingye put on his goggles and checked his lab coat and dust cap again to make sure that no new debris would fall off due to his own actions.

Ready, he stepped into the wreckage of the arrow.

The interior space is very large, especially with a diameter of three meters. Standing inside, even your breath will echo.

Song Xingye couldn't immediately tell which type of rocket the debris belonged to.

After all, the Great Wall series rockets from Dongyu Group seem to all be designed with a diameter of 3.35 meters.

He shone a flashlight and began to explore the area from where he had come in.

This is a job that requires extreme patience and keen eyesight, and it is also one of the essential qualities of an aerospace worker.

One minute on stage requires ten years of practice off stage.

Rocket launches take only a few minutes, but the ground phase often takes months or even years!

Especially once in space, any tiny particle can cause short circuits, jam mechanisms, and ultimately render a multi-billion dollar launch mission a failure.

After looking at the light for a while, Song Xingye quickly found a piece of polyimide tape.

This thing is only 2 millimeters long on each side.

However, a cunning technician secretly stuck it onto the same golden-yellow insulation layer component.

If Song Xingye hadn't noticed the unusual angle of the reflection when he shone the flashlight, he would have definitely missed it.

"That's really cunning..."

He collected the debris into a bag and continued on his way.

Soon, they found the remnants of cable ties sandwiched between two thick cables in the gaps of the cable bundle.

This is the small square end left after the white nylon cable tie was cut.

Next, a black antistatic brush bristle was found on the surface of the carbon fiber honeycomb panel.

Song Xingye put them all away.

Beside an electrical connector plug, he crouched down and used a magnifying glass to repeatedly examine a small silver metal ball—

That wasn't a solder joint, but a piece of solder residue only a fraction of a millimeter in diameter.

With a gentle rub, it came off.

If you're not careful, it can easily be mistaken for a solder joint.

In the blink of an eye, five spoils were already lying in the bag.

Song Xingye stretched his shoulders and felt quite relaxed.

Then, Song Xingye slowly lay down, kneeling on one knee on the aluminum alloy surface of the arrow wreckage, and shone a flashlight into the chamfered inner wall of a threaded hole.

This is also a place where mistakes often occur in aerospace engineering, which has been repeatedly emphasized during quality analysis meetings in the past.

Sure enough, Song Xingye reached in and dug around, finding a spiral-shaped piece of aluminum wire left over from drilling.

He breathed a sigh of relief, stood up, and continued searching.

Next to a metal nut, I found a small transparent plastic ring.

Because it is transparent, the small ring is pressed under the nut and is almost indistinguishable to the naked eye.

But who is Song Xingye? He is a senior expert who has spent many years sitting on the sidelines and worked his way up to the position of chief engineer. His eyes are like a ruler!

As he passed the components secured by these nuts, he became extremely sensitive and sensed that something was wrong.

Perhaps it was a sixth sense, or perhaps it was a subtle flaw in what the eye could see.

Then, Song Xingye narrowed his eyes and determined that the heights of the nuts on both sides were inconsistent.

Finally, the extra little ring was removed.

He finally breathed a sigh of relief.

He weighed the small plastic piece in his hand. Although it only raised the nut by 0.5 millimeters, in aerospace engineering, even the slightest deviation can cause a difference in the preload of the bolts on the two components when the rocket is moving at high speed.

This difference will amplify with vibration, and may even cause the screws to come loose!

Chief Engineer Song was very satisfied with his sixth sense and continued searching with great confidence.

He walked all the way to the end, and from one of the protruding, sharp bristles, he plucked a slightly curved eyelash.

The ninth extra item was also located at the same time.

After Song Xingye put his eyelashes away, his gaze naturally fell on the rocket skin under his feet.

He stared at the screws on the skin for a while, then turned away.

Since the skin of the rocket body is basically symmetrical, there is no distinction between top, bottom, left, and right. However, since the rocket wreckage is placed like this, the default foothold is the bottom.

Song Xingye raised his flashlight and shone it overhead for a long time.

After finding a similar structure, I counted the number of screws on it.

One is missing.

After confirming that his judgment was correct, he deftly squatted down and unscrewed the extra screw from the row of seemingly normal screws at his feet.

That's right, this is a 'redundant' item disguised as a normal part!

Song Xingye analyzed that this should be a reserved hole, or it may be used to install other equipment.

But the cunning technician used an extra screw to disguise it as a normal part, trying to mislead the reporter.

If I hadn't been careful, I would have almost been fooled.

This hole should have been empty.

Looking at the pile of miscellaneous items he had collected in the bag, Song Xingye felt quite satisfied.

He figured that not much time had passed, and there was still plenty of time to find the last one.

But it's all over now.

Did someone slip through the net just now, and we didn't even notice them right under our noses?

Song Xingye dared not draw any conclusions, nor did he lose his composure. Instead, he retreated backwards from the innermost part of the arrow wreckage along the original path.

Sweep back little by little, like clearing mines.

This time, he was only one short, but he didn't dare to let his guard down. It was precisely at times like these that he had to be patient.

Try to find it in one go.

Therefore, Song Xingye observed very carefully, his bright eyes scanning back and forth with the flashlight.

However, after scanning the area, I found nothing!

Song Xingye stood there, his brows slightly furrowed.

The search for this last FOD took longer than the previous nine combined.

But where will it be hidden?

Considering that Li Ang and General Manager Liang and their team like to secretly dig holes, maybe they've dug one too this time?

Song Xingye's mind raced, and he began to daydream.

Imagine... you are an aerospace engineer right now... this is the final check before the rocket leaves the factory...

After immersing himself in the role, Song Xingye closed his eyes for a few seconds to rest before opening them again.

Eyes ejaculate.

The wreckage of the arrow was quiet, save for the scraping sound of shoes stepping on the aluminum alloy skin...

The scorer standing outside stared at the timer in his hand with a bored expression, but a smile he couldn't suppress was playing on his lips.

Jiang Mian, who was at the back of the line, whispered to her roommate Zhao Yuehe:

"Why does it feel so quiet inside? Is Song Shen just standing there spacing out?"

Zhao Yuehe listened intently for a while, "It seems like he's spacing out... I wonder what he's discovered, why isn't he moving? This round of assessment is all about making the most of every second!"

However, the footsteps on the aluminum alloy skin soon became clear again.

And it's getting closer and closer.

Song Xingye walked out with a stoop.

He neatly arranged the flashlight, goggles, and magnifying glass on the table, then handed the bag containing the items to the scorer.

The initially bored scorer's expression became quite interesting after clicking to stop the timer:

"Hey... not bad, kid, you finished so quickly, you've got some skills..."

As he spoke, he took the bag that Song Xingye handed him.

After carefully counting the FODs, he gave an approving look. "Alright, you can go now. Next, Jiang Mian!"

Song Xingye turned and left with a relaxed expression.

As evening approached, everyone had finished "finding faults" with the arrow wreckage.

Most of the students crawled out of the wreckage with apprehension, clearly unsure of their results.

Li Ang collected all the rating sheets and looked around at everyone with a smile:

"Thank you for your hard work today. The results of the third round of assessments will be announced tomorrow along with the results of the second round."

"Take a good shower and relax tonight, then just wait for the results tomorrow. After the results are announced this morning, you'll have half a day off to do whatever you want, okay?"

Upon hearing that they would have a half-day off, the students, who had been tense all day, finally showed joy and nodded repeatedly.

Then they lined up and boarded the bus to return to the group headquarters.

Two rounds of assessments were conducted in one day, and with 14 students set to be eliminated the following day, no one was in the mood to play anymore when they returned to the family compound.

After queuing up to wash up, everyone went back to their rooms to rest.

Song Xingye, on the other hand, was full of energy. He first called Qin Rui from Jiaotong University to inquire about the progress of his thesis and then gave Chen Xin guidance on revising his paper for CTOC.

Finally, I played Fruit Ninja on my phone for a while before turning off the lights and going to bed.

The next morning, 73 students gathered in the multi-functional conference hall.

Mr. Liang and his team did not show up, presumably because they were busy. Only their mentor, Li Ang, walked onto the stage with the list in his hands.

Everyone's hearts jumped into their throats.
