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

Magic City.

Shanghai Jiao Tong University, Minhang Campus.

The Sky Building, third floor laboratory.

Song Xingye opened his eyes groggily.

Then, he suddenly sat up.

"Wasn't I in the assembly workshop of the Great Wall-9 rocket, troubleshooting a malfunction in the fuel tank, when the explosion occurred?"

Song Xingye rubbed his aching temples and looked around blankly: "Where am I again?"

He muttered something subconsciously, but was surprised to find that the Dell computer screen in front of him displayed the time in the lower right corner—

October 2011, 5!

Song Xingye was stunned.

How is that possible...? Did an explosion transport me back twenty years?

Is this a rebirth?

The surroundings were a familiar laboratory layout, with whiteboards densely covered with Kepler equations and orbital elements, and several textbooks on "Spacecraft Orbital Dynamics" and "Numerical Analysis" piled up in the corner.

Outside the window is Siyuan Lake, the iconic landmark of the Minhang campus, and the outline of the "Slipper Gate" is faintly visible among the lush trees in the distance.

Song Xingye pinched his thigh hard, and the sharp pain confirmed that he was not dreaming.

I've truly been reborn!

Song Xingye never expected that after wasting half his life, he would return to 2011 due to an accident.

At the same time, a voice suddenly rang in my mind.

[Ding! Fault Prediction Eye skill activated!]

[Skill Effect: After activating the skill, the host's field of vision will be overlaid with an "error correction layer". Based on the logical loop of the host's existing knowledge base, it performs ultra-fast subconscious deductions on the blueprints, formulas, mechanical structures or experimental plans within the host's field of vision.]

When a potentially fatal vulnerability is discovered that could lead to the failure of future missions, it will be marked with a highlighted red box.

Upon hearing this, Song Xingye's emotions surged violently.

This thing... could it be a perk for reborn people?

A fault-predicting eye?

As an aerospace engineer, he knew all too well what this capability meant.

Aerospace is an industry where "ten thousand people work together with one gun." There are tens of thousands of parts, blueprints, and codes. If any link goes wrong, billions of dollars in investment and the hard work of countless people can be wiped out in an instant.

Therefore, the most troublesome thing in this field is "resetting to zero"!

If we had a fault-predicting eye, wouldn't those faults that would take months and countless simulations to locate be instantly recognizable?

From now on, all the black boxes and uncertainties in the field of engineering will be laid bare in his eyes.

Thinking of this, Song Xingye's breathing became heavy.

With this golden finger blessing, the path of space exploration in this life is destined to be boundless!

[Note ① Knowing what happens, but not why: This skill only indicates the location of the fault, without providing the cause, solution, or simulation of the consequences.]

[Note ② Cognition determines the upper limit: The prerequisite for a skill to take effect is that the host must fully understand the underlying logic and operating principles of the observed object. It cannot be used on objects outside the host's cognitive understanding (such as unfamiliar interdisciplinary blueprints or equipment).]

[Note ③ Mental Load: Skills consume the host's mental energy. The higher the complexity of the observed system and the longer the deduction time span, the mental energy consumption increases exponentially. Overuse will lead to dizziness, shock, or even brain death!]

The sound that followed immediately calmed Song Xingye's agitated heart.

So, the fault-predicting eye isn't omnipotent after all.

Song Xingye pondered the hint he had just received, his mind racing as he extracted the core logic:

In short, this skill will only report errors; as for how to fix it, you'll have to figure it out yourself.

Its own knowledge base determines the scope of its error reporting.

Finally, this skill is extremely mana-intensive.

Looking at a simple blueprint might only take a moment; but if you're staring at a rocket assembly drawing with tens of thousands of parts looking for flaws, your brain might overload and crash in a second.

That's all the information provided.

The skill descriptions are simple and straightforward.

Song Xingye rubbed his face and couldn't help but sigh.

I thought I could finally relax and rely on the system, but it turns out I'm still going to be stuck.

Only with extensive knowledge can one possess a powerful advantage; the harder one works, the more invincible one becomes!

Although Song Xingye had some regrets, he was also content.

After all, this is the "eagle eye" that aerospace engineers dream of, truly priceless!

"Hoshino, wake up!"

A somewhat weary voice called from the side.

Song Xingye turned his head and saw a boy with messy hair and black-rimmed glasses staring at the screen.

"Old Qin?" he blurted out.

Qin Rui, his roommate during his doctoral studies, was a computer genius who joined the Ninth Academy of Aerospace Science and Technology under the Dongyu Group after graduation.

Unfortunately, during a satellite orbit change mission, he lost track of a satellite due to a calculation error. He never recovered and resigned to work for a private rocket company. Later, he switched careers to sell insurance.

Although Qin Rui looked exhausted, he was still the same spirited young man.

"Stop daydreaming, get back to work after you've rested enough! There are only 48 hours left until the competition ends!"

Qin Rui typed rapidly on the keyboard, groaning as he stared at the screen: "This year's organizers are absolutely insane! They've used the Jupiter system multiple times to fly... Our genetic algorithm converges too slowly; we simply can't reduce fuel consumption!"

These words instantly awakened Song Xingye's long-dormant memories.

In 2011, the CTOC National Track Design Competition's theme was "Jupiter's Grand Tour".

In short, participants need to design a low-thrust probe orbit to conduct comprehensive mapping of Io, Europa, Ganymede, and Callisto through multiple close flybys of the Jupiter system.

Whoever designs the orbit that consumes the least amount of fuel wins the gold medal.

In that competition, Song Xingye and his team's orbital design was deemed "infeasible" during the judging process due to an extremely subtle orbital integration error, resulting in them finishing last and not winning a single medal.

And now, the gears of fate have turned back to this moment.

Just as Qin Rui was going crazy, a flattened hairstyle was lifted up on the opposite table, revealing a helpless face:

"Rui, that's enough. Our Jiaotong University's aerospace engineering department is newly established and has a weak foundation. How can we compare with established universities like Beihang University and Harbin Institute of Technology? We're just here to make up the numbers. We should be ashamed and strive to improve. Losing isn't shameful..."

The speaker was Chen Xin, a junior student from the mathematics department.

Song Xingye acts as the "physics brain" in the group, responsible for thoroughly understanding the problems and breaking down the physical models;

Chen Xin acts as the "mathematical brain," designing algorithms and optimizing the whole system.

Finally, Qin Rui, the "programming brain," built a simulation framework that allowed the physical model and mathematical formulas to run on the computer.

The three of them together were the main force of Jiaotong University's team.

Listening to Chen Xin's words, Qin Rui scratched his head in frustration.

"I know participation is the key... but the gap is just too big! I heard that Beihang University's plan has a fuel consumption that's 15% lower than ours. What's the point of even competing with that?"

Chen Xin shrugged: "Their advisors are all academicians of the Chinese Academy of Sciences and the Chinese Academy of Engineering. We didn't have any advantage to begin with..."

"Don't panic, let me take a look."

A steady voice suddenly broke in.

That is absolute confidence born from two lifetimes and two decades of dedicated work in the aerospace industry.

Song Xingye adjusted his posture and moved closer to the computer in front of Qin Rui.

The image above shows a densely packed C++ code and a Matlab simulation interface.

The moment he looked at the screen, a miraculous thing happened—

In the code interface that was originally black with white text, a function responsible for calculating the 'gravity-assisted orbital change angle' was suddenly selected and highlighted in red!

Ok?

Song Xingye subconsciously glanced at Qin Rui beside him.

The other party didn't react at all, still staring at the screen with a worried expression.

Obviously, only you can see this red box.

The locked function... is the core segment used to calculate Ganymede's gravitational slingshot.

Is this what they call a "fault prediction eye"?

Song Xingye closed his eyes, then opened them again.

The red light is still there, and it only appears when you are staring at those specific lines of code.

"Hoshino, are you alright? Why do you look so strange?"

Qin Rui waved his hand in front of his eyes, "If you're too tired, take a break. Leave this part of the track optimization to me and Chen Xin."

"No need, I'm fine." Song Xingye shook his head.

The cheat code will only "highlight" the information in red, without providing any explanation.

This is like a teacher marking a big X on a test paper but not telling you the correct answer.

But that was enough for Song Xingye.

Even without a system, his twenty years of engineering experience allowed him to find vulnerabilities.

Now, this process has been accelerated infinitely.

"Old Qin, delete lines 432 to 445 and have Chen Xin rewrite an approximate solution to the Navier-Stokes equations."

Qin Rui asked doubtfully, "Is there anything wrong with this function? Chen Xin checked it five times, right?"

Chen Xin, standing nearby, was also puzzled. "Senior Brother Song, this is the core algorithm for handling Ganymede's gravitational slingshot. The theoretical derivation is correct, isn't it?"

Song Xingye pointed to the 'reddish-purple' function in his field of vision and said calmly:

"The theory is correct, but the precision is overflowing."

He turned to look at Qin Rui, his gaze sharp: "Do you know why the convergence speed is slow? During polar coordinate transformation, the precision loss of floating-point numbers is amplified exponentially during multiple orbital changes."

Following this algorithm, the probe will end up like a blind person, crashing headfirst into the icy surface of Europa!

"Is...it really that serious?"

Chen Xin never expected that such a vulnerability would be discovered in the function he wrote.

Qin Rui also looked hesitant.

Don't believe me?

Song Xingye didn't explain further, snatched the mouse, and skillfully brought up the compiler debugging window.

"Then run a partial simulation. Don't just run the third orbital change; add the fourth and fifth as well. Once the variables are combined, the loopholes will be exposed."

Then, he skillfully typed in several commands, his fingers flying across the keyboard.

Finally, press the Enter key.

The fan noise suddenly increased.

Ten minutes later.

A red dialog box popped up on the screen:

[Simulation failed, rigid impact detected!]

Below the dialog box is a clear red line indicating the impact rate.

The laboratory fell silent instantly.

Chen Xin was stunned, and Qin Rui exclaimed incredulously, "Holy crap...they really crashed?"

"Since this function has a problem, the rest is simple."

Song Xingye flexed his wrists, as if he had only just tested his skills, and said calmly:

"No need for too many changes. Just make the step size of the Runge-Kutta method dynamically adjusted, and add an error compensation term, and it will meet the dynamic constraints..."
