1: Chapter 1: On the day of the breakup, I awakened the "Many Children, Many Blessings" system!

"Lin Yun, let's break up."

The cold voice, like a biting wind in the dead of winter, seeped out from the phone receiver, sending a shiver through Lin Yun's entire body.

He was standing at the entrance of his third-tier university, holding a bag of freshly roasted, steaming sugar-fried chestnuts in his hand.

These were his girlfriend Zhao Lulu's favorite.

"Lulu, are you... are you joking? Didn't we agree that once I graduate and find a job, we would..."

"Job? Lin Yun, wake up!"

On the other end of the line, Zhao Lulu's voice was filled with undisguised contempt and impatience. "What kind of good job can a graduate from a crappy third-tier school like you find? Three thousand a month? Five thousand? Can I afford to wait?"

"I..." Lin Yun's heart instantly sank to the bottom.

"I don't want to live this kind of life with you where I can see the end from the beginning anymore! Do you know what Wang Feng bought me? The latest Chanel bag! Do you know who his father is? A director of a listed company! What about you? What do you have?"

"Lin Yun, let me be blunt with you. My mom introduced me to a match, and it's Wang Feng. We're getting engaged next month. From now on, don't contact me again."

Beep... beep... beep...

The call was ruthlessly disconnected.

Lin Yun froze in place. The warm sugar-fried chestnuts in his hand now felt like red-hot iron, burning his palm with pain.

People passed by all around him, and the youthful laughter sounded like needles pricking his eardrums.

Humiliation, anger, resentment... various emotions surged like overwhelming waves, nearly swallowing him whole!

Three years!

Three whole years of a relationship!

He had lived frugally to give her the best, and what was the result? In the end, it was all traded for being called 'crappy third-tier' and a comparison to a Chanel bag!

"Heh..."

Lin Yun laughed self-mockingly, laughing until tears almost came out.

He suddenly raised his hand, wanting to smash that bag of ironic chestnuts fiercely onto the ground!

But at the very moment his arm swung halfway through the air—

[Ding!]

A cold, grand, and emotionless mechanical voice, like a divine oracle from beyond the heavens, exploded directly in his mind!

[Detected that the host has encountered strong emotional betrayal, meeting the conditions for 'Survival through Despair'...]

['Multi-Child Blessing · Black Tech System' is activating...]

[10%... 50%... 100%!]

[Activation successful!]

Lin Yun's body instantly froze, his arm still held in that comical posture.

An illusion?

Had he been so stimulated that he'd lost his mind?

[This system is dedicated to assisting the host in proliferating his bloodline, sowing the seeds of civilization, and driving the leap of human civilization.]

[As long as the host produces offspring, you can obtain black tech rewards beyond the era based on the offspring's potential!]

[Offspring potential is divided into four grades: S, A, B, and C. The higher the overall quality of the partner, the greater the probability of birthing high-potential offspring!]

A series of information streams, like a data waterfall, flooded frantically into Lin Yun's brain!

He wasn't dreaming!

As a veteran web novel enthusiast, he understood instantly!

A system!

This was his golden finger!

He had transmigrated to this parallel Blue Planet, which was highly similar to Earth but lagged nearly twenty years behind in technology—especially in cutting-edge fields. After living aimlessly for twenty-two years, the system had finally arrived!

Multi-child... blessing?

Just by having children, he could obtain black tech?

Lin Yun's breathing instantly became rapid!

Black tech!

He knew all too well what those two words meant!

In this world, although the Dragon Kingdom was massive, its cutting-edge technology was being throttled everywhere by the West, especially Eagle Sauce Country.

Chips, lithography machines, aero-engines, biopharmaceuticals... countless fields were subject to others' control!

Whenever he saw news about Eagle Sauce imposing technology blockades on the Dragon Kingdom in yet another field, Lin Yun's teeth would itch with rage!

And now, he had the possibility to change all of that!

[Ding! Detected the host's first activation of the system. Issuing a Newbie Gift Pack!]

[Congratulations, host, for obtaining: god-level physique strengthening serum (Completely optimizes genes, enhancing physical fitness to the human peak)]

[Congratulations, host, for obtaining: One Newbie-level Black Tech Blueprint (Field can be specified)]

"Holy crap!"

Lin Yun couldn't help but curse in his heart, his heart pounding wildly!

God-level Physique strengthening!

Isn't this the 'marrow cleansing' from novels?

He looked down at his somewhat weak body, then thought of the system's core function of 'Multi-Child Blessing,' and the corners of his mouth couldn't help but curl up slightly.

The body is the capital of revolution. The system is... afraid I'll be too exhausted later, so it's strengthening my foundation in advance!

How thoughtful!

As for that Newbie-level Black Tech Blueprint...

Lin Yun's eyes instantly became incredibly burning!

He had almost no hesitation!

"System, I specify... the field of aero-engines!"

Aero-engines!

The jewel in the crown of industry!

A field where countless researchers in the Dragon Kingdom had spent their life's work, yet a huge gap still remained compared to the world's top level!

This was also the eternal pain in the heart of the Dragon Kingdom's Air Force!

[Command confirmed! Newbie-level Black Tech Blueprint generated!]

[Congratulations, host, for obtaining: "Kunlun" WS-30 High Thrust-to-Weight Ratio Aero-engine Full Design Blueprints and Detailed Manufacturing Processes!]

Boom!

When this name and the associated massive data stream flooded his mind, Lin Yun felt as if his scalp was exploding!

Even though he was just a student from a third-tier school, he still had basic common sense!

Thrust-to-weight ratio!

This was the core metric for measuring aero-engine performance!

In today's world, Eagle Sauce's most advanced F-22 Raptor fighter, with its F119 engine, only barely reached a thrust-to-weight ratio of 10!

Yet the blueprints in his head, for this engine named "Kunlun," had a maximum thrust-to-weight ratio that reached a terrifying level of—15!

This wasn't just being one era ahead!

This was practically pinning Eagle Sauce to the ground and grinding them with future technology!

Lin Yun clenched his fists tightly, making the bag of sugar-fried chestnuts creak under the pressure.

Zhao Lulu? Wang Feng?

Chanel? Listed companies?

In the face of black tech capable of changing the global landscape, these things... were worth nothing!

From this moment on, his world was already completely different from theirs!

A crazy thought began to sprout and spread uncontrollably in his mind!

Rely on himself to research it?

What a joke!

As a third-tier graduate, he couldn't even find a decent lab. Even if he printed the blueprints out, they would just be a pile of scrap paper!

To turn these god-level technologies into reality, there was only one choice!

A... decision that went against his ancestors!

Lin Yun took a deep breath. The confusion and pain in his eyes were swept away, replaced by an unprecedented determination and fanaticism!

He pulled out his phone, ignored the heartless text from Zhao Lulu telling him to stop harassing her, and directly opened the map to search for a location he never thought he would proactively search for in his life.

—Dragon Kingdom Ministry of State Security, Jiangcheng Branch!

Looking at that solemn red marker on the map, a crazy arc curled at the corner of Lin Yun's mouth.

"Leaders, I don't want to work hard anymore..."

"I want to have children for the country!"
