Chapter 9: Sonoluminescence Phenomenon
Early the next morning, just as dawn broke, Lü Yongchang got up and left the dormitory.
This was a habit he had developed in his previous life.
The September morning carried a slight chill in the wind.
Staring at the empty main road of the university, Lü Yongchang couldn't help but fall into deep thought.
Where… should he go?
Perhaps due to the habits ingrained in his past life, Lü Yongchang felt an inexplicable emptiness without a research project in hand.
He had no idea how the review of his controlled nuclear fusion proposal was going…
Surely… nothing would go wrong, right?
Although he was confident in the proposal, he had little confidence in his current identity.
Right now, he was just an ordinary sophomore at Sandao University.
Looking back, even he felt his actions had been reckless.
But remembering that he only had twenty short years, Lü Yongchang sighed helplessly.
He had no time to waste!
The Earth was home to 8 billion people!
To transport all 8 billion humans into space and reach the next habitable planet… the level of technology required was staggering!
Originally, in his plan, if even 10 million humans could escape, it would have been considered an incredible stroke of luck.
But after learning of the existence of the Technology Tree System, his mind began racing with possibilities.
Perhaps… if he advanced the technology quickly enough, all of humanity could escape Earth alive!
If Level 1 civilization wasn't enough, then Level 2!
And if that still wasn't enough… he refused to believe that even Level 3 civilization couldn't achieve it!
Lost in thoughts about the next twenty years, Lü Yongchang wandered aimlessly across campus.
Suddenly, his peripheral vision caught sight of a familiar building.
A pure white structure.
This was… the Sandao University library!
His eyes flickered slightly, and he turned toward it.
Entering the library, Lü Yongchang instinctively followed muscle memory to his favorite spot from his past life.
No one had taken it!
A glimmer of joy flashed in his eyes.
But… what should he read?
His mind stirred.
He recalled the prompt from the Technology Tree System.
[Prerequisite: Analyze Sonoluminescence Phenomenon]
It seemed he needed to find books on sonoluminescence!
…
Time always flew when immersed in reading.
In the blink of an eye, over two hours had passed.
Closing the book in front of him, Lü Yongchang pensively jotted down a few key points on a sheet of A4 paper.
Mantis shrimp!
The phenomenon of sonoluminescence was first observed in nature in a creature called the mantis shrimp.
When attacking prey, the mantis shrimp could snap its appendage forward in 1/50,000th of a second, reaching speeds exceeding 80 km/h, with acceleration comparable to a bullet!
During this process, sonoluminescence occurred!
This phenomenon had since been studied extensively by researchers.
The principle was simple: when mechanical waves acted on a liquid, they produced acoustic cavitation—tiny bubbles formed in the liquid and then collapsed to an extremely small volume.
During this collapse, the interior of the bubble reached extremely high temperatures, emitting a brief flash of light in that instant!
Lü Yongchang seized upon a critical detail.
The interior of the bubble reached extreme temperatures!
It seemed… the key to fusion reactor miniaturization lay in this tiny bubble!
After all, nuclear fusion required temperatures exceeding 100 million degrees Celsius as a prerequisite!
"Excuse me, is this seat taken?"
Just as Lü Yongchang was deep in research, a slightly cool female voice reached his ears.
This voice… why did it sound so familiar?
He jerked his head up and looked to the side.
The moment he saw the speaker, his heart clenched violently.
It was her!
His sudden reaction clearly startled the girl.
She took a step back, quickly apologizing, "Sorry, sorry! If someone's sitting here, I can—"
"No one! Take a seat!"
Lü Yongchang cut her off, then forced an awkward smile. "I—I was just startled. My reaction was a bit much, sorry."
The girl waved her hand with a smile. "No worries! I was the one who asked too abruptly!"
With that, she confidently sat down beside him.
Gazing at her profile, Lü Yongchang felt a wave of déjà vu.
It was just like his past life.
Back then, Su Yutong had also sat quietly beside him, assisting with various research tasks.
Sensing his stare, the girl looked up at him.
"Um… hello?"
She tilted her head slightly, puzzled. "Is something wrong?"
He snapped back to reality, biting his tongue hard—the sharp pain pulling him out of his memories.
"No, nothing! You just… look familiar."
With that, he forced himself to turn away and refocus on the papers in front of him.
The girl gave him a strange look and subtly shifted her chair away.
Something about his gaze felt… off.
She was starting to regret sitting here.
As for Lü Yongchang, he remained oblivious to her thoughts, now engrossed in a particular paper.
"On the Relationship Between Sonoluminescence and Cold Fusion"
The moment he saw the title, his breath hitched.
Could it be… someone had already cracked fusion reactor miniaturization?
Impossible!
In his past life, even controlled nuclear fusion wasn't achieved until 2040, let alone miniaturization!
That meant, under normal circumstances, true controlled nuclear fusion was still a decade away!
He quickly skimmed through the paper.
After a long while, he exhaled slowly, relief flashing in his eyes.
He had overthought it.
This paper was just speculation, with no substantial research.
Practically useless.
No wonder… he had never come across it in his past life!
His eyes dropped to the author's name.
Tao Yuda.
He might seek him out for a discussion later.
Though the paper itself was worthless, the scientific intuition behind it was spot-on.
If this Tao Yuda had real potential, Lü Yongchang wouldn't mind recruiting him for his future research team!
"Click… click… click…"
Just as he was deep in thought, the sound of a ballpoint pen's ratchet mechanism came from beside him.
