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

Ten minutes later, the three of them sat down at the "Yudu Malatang" restaurant on South Street.

The shop is narrow and the aisles are cramped. The air is filled with the rich aroma of Sichuan peppercorns and butter. Several folding tables are full of diners, creating a noisy and bustling atmosphere.

The owner worked quickly, serving three bowls of steaming hot and spicy tang, along with several sizzling lamb skewers and three bottles of chilled soda with water droplets clinging to them.

"Thank you, boss!"

Song Xingye couldn't wait to take a bite, and it tasted just like before.

After taking a few bites, he picked up a long-handled steel spoon from a tin can, scooped up a large chunk of yellow ointment, stirred it in, and then ate it with great satisfaction.

The spicy flavor hit his throat, and Song Xingye glanced at the slightly worn-out furnishings around him out of the corner of his eye, feeling a mix of emotions.

After wasting half a lifetime, who could have imagined that there would actually be a day when I could return to my youth?

Memories of my past life flooded back like a tide.

Back then, he was so full of vigor and ambition when he was admitted to Jiaotong University through the gifted youth program, went straight to his doctoral degree, and was recruited by Dongyu Group to be trained as a young backbone!

Back then, he was known as a "workaholic" by his colleagues and a "hothead" by his superiors. He was so serious about his work that he was almost stubborn, and he didn't understand interpersonal relationships. He even dared to openly contradict his superiors in a meeting over a technical parameter.

Promotion, awards, and professional titles were naturally out of his reach.

Later, a transfer order made him think that he had finally "seen the light at the end of the tunnel" and was promoted to acting factory manager in a certain place.

When I got there, I realized it was "exile"!

It was a factory on the verge of bankruptcy, having lost three factory managers in succession; it was a "workplace graveyard" where whoever went there died.

He refused to believe in bad luck and carried out sweeping reforms in an attempt to turn the factory around. However, due to his straightforward personality, he was ostracized and completely sidelined, and in the end, he could only watch helplessly as the factory went bankrupt.

This incident almost completely impacted his career advancement!

Whenever Song Xingye is mentioned, all the leaders think of words like mediocre, pedantic, and incompetent.

Although he eventually rose to the position of chief engineer, it was through years of hard work and seniority that he earned his position.

From then on, Song Xingye finally understood a principle—

In this life, one should blend in with the world, being outwardly flexible but inwardly principled; one should avoid seeing things in black and white and being blindly devoted to technology!

It's a pity I realized it too late.

just now……

Song Xingye raised his head proudly.

Since God has given me a second chance, I must live with pride this time!

I must never be that stubborn, naive boy I used to be again.

……

After eating spicy hot pot, the three of them went back to the lab.

Song Xingye continued to use his precognitive abilities to optimize the competition plan for the "Jupiter Grand Tour".

Because of the introduction of complex algorithms such as differential correction method, Pontryagin extremum principle, Poincaré section, Hamiltonian mechanics and Fourier transform, the following time was definitely tedious and agonizing for Qin Rui and Chen Xin.

But for Song Xingye, this is enjoyment, this is art.

The clicking of the computer and the hissing of the whiteboard drawing tracks blended together.

Differential equations cut complex orbits into countless fragments, while integral equations precisely stitch them together.

Song Xingye acted like a supervisor, busy with his own work while also effortlessly directing the two assistants:

"Cut off the third acceleration phase! That's tangential thrust, a pure waste of momentum."

"Here, we introduce a nonlinear perturbation term! By utilizing the gravitational resonance of Io, we can directly circumvent the influence of the radiation belts."

"Imagine the gravitational field as a fluid. Utilizing the weak Lagrange point perturbations between Jupiter's moons, we'll hop between them like hitchhiking, understand?"

"..."

Two days later, Qin Rui and Chen Xin were thrilled when they looked at the final draft of the track design.

The trajectory is so perfect it's like a work of art, and the total pulse ∆V has dropped to 1400 m/s.

The smaller ∆V is, the less fuel is consumed!

"Quick, pack the data! There are only twenty minutes left until the deadline!"

Qin Rui's shout brought Chen Xin back to his senses, who was immersed in excitement.

Song Xingye remained as steady as a mountain, and until the very last moment, he was still using the "Fault Prediction Eye" to check the plan.

There is no red box and no error message.

This means that the solution is flawless in terms of engineering logic and physical laws.

Qin Rui finally clicked the submit button.

Seeing that the email had been successfully sent, the three of them finally relaxed completely after being on edge for two days.

"call……"

Qin Rui slumped into his chair, took off his glasses, and rubbed his bloodshot eyes, saying:

"This plan... I wouldn't dare say it'll win gold, but it should at least secure a top-three finish, right?"

"Top three?"

Song Xingye chuckled, arms crossed, "You're underestimating this algorithm based on the Pontryagin principle. It's bound to win the gold medal!"

"Gold... gold medal?"

Qin Rui and Chen Xin swallowed hard.

"Alright, stop making wild guesses."

Song Xingye stood up, patted the two on the shoulders, and said, "Pack your things and go back to your dorm to catch up on some sleep. Leave the rest to the judges. Who knows, when we wake up, our Jiaotong University's name will be known throughout the entire aerospace community!"

……

Jingzhou, Friendship Hotel.

This is the venue and data center for this year's Rail Design Competition.

Inside the spacious and brightly lit conference room, several professors and experts were chatting casually while sipping coffee.

"This year's questions were quite difficult, especially the gravitational resonance trap on Europa, which was a real pitfall."

The speaker was an elderly man with a full head of white hair, Professor Luo from Beihang University, who was also the one who set the questions for this year's exam.

He took a sip of coffee and said, "I don't believe any team can break through the 1500m/s barrier with their ∆V!"

"Indeed. Among the currently approved proposals, the Beihang University team is temporarily in first place with a speed of 1520 meters per second."

"Tsinghua and Peking Universities also performed well. Ironically, the number of participants from Harbin Institute of Technology and the University of Chinese Academy of Sciences this year wasn't as strong as in previous years, haha..."

Just then, a new proposal was delivered to the review site.

The assistant next to him whispered, "Professor Luo, this is the last one. The participating team is from Jiaotong University."

"Jiao Tong University?"

Professor Luo chuckled lightly upon hearing this, "Isn't their aerospace engineering department only been established for a few years? Why are they getting involved in this mess?"

What he said was true; compared to the other established powerhouse teams in the competition, the Department of Aerospace Engineering at Jiaotong University was indeed too young and too weak.

However, adhering to the principle of emphasizing participation, Professor Luo still reviewed the proposal along with the other reviewers.

Half an hour later, Professor Luo, who had been somewhat nonchalant, sat up straight with a furrowed brow.

The orbital diagram submitted by Jiaotong University not only has the lowest fuel consumption, but also has an incredible aesthetic appeal!

Professor Luo quickly called his assistant: "Quick! Project the simulation model from Jiaotong University onto the big screen and run it for verification immediately!"

The assistant was startled and frantically tried to operate the device.

Soon after, the big screen lit up.

One can see complex segments of orbital data being loaded into a high-precision integrator.

The progress bar started spinning rapidly.

All the review experts had their eyes glued to the screen.

They eagerly awaited the "collision" or "escape" error message to appear in the next second.

After all, no one could believe that the aerospace department of Jiaotong University, which had only been established for a few years, would produce students who were more outstanding than those from established prestigious universities.

however.

Time passed second by second.

In the simulation model, the probe moves through the Jupiter system like a butterfly.

Each orbital change made perfect use of Jupiter's gravitational slingshot, greatly saving its own fuel consumption.

Flowing like clouds and water, fraught with danger yet as steady as a rock!

When the green light indicating the final task was completed came on, the room fell silent.

After a long silence, Professor Luo took off his reading glasses and slowly said:

"This isn't calculation...this is art."

"Ladies and gentlemen, I think the gold medal in this competition is already a foregone conclusion!"
