Let me show you something precious...

At that very moment,

Lu Xiaobai's expression shifted slightly. He spotted Du An walking into the classroom from outside and promptly called out,

"Old Du!"

Du An was slightly taken aback, a look of confusion flashing in his eyes as he pointed at himself.

"Lu... Lu Xiaobai, are you calling me?"

His demeanor was somewhat stiff, and a thread of unease wormed its way into his heart.

In the past, his consistent position as the top student in the class had fostered an arrogant personality. He often looked down upon the underachievers in the class, which naturally included Lu Xiaobai, who was perpetually last.

Now that the other's true status had been revealed, he was worried about facing payback...

"It's a small matter..."

Lu Xiaobai smiled and nodded, about to initiate a friendly conversation.

But just then,

The class bell rang, forcing him to postpone the matter and return to his seat.

A young man wearing black-rimmed glasses strode in.

"Class, this period is math. Let's continue from where we left off the day before yesterday..."

"Mr. Wu, you've recovered from your illness?" a student asked with a smile.

"Ahem..."

Wu Yuan rubbed his nose, glanced at the student, and said with a chuckle,

"When your Teacher Nangong gives an order, I pretty much have to get sick."

The class couldn't help but laugh at his words, and the atmosphere in the classroom seemed quite harmonious.

In fact,

Apart from Nangong Ling, all the other teachers responsible for theoretical subjects were extremely amiable.

"Alright, let's begin the class."

Wu Yuan switched on the projector on the podium. A large virtual screen instantly appeared, displaying various complex mathematical equations.

"Today, we'll continue explaining the energy formula related to wormhole jumps..."

The students below looked up at the complex equations. Some wore bewildered expressions, others frowned in concentration, while a few appeared completely at ease.

For students with higher Life Force levels, their minds were more expansive and their intellect sharper. Grasping theoretical knowledge came almost naturally to them. This was precisely why this era placed such importance on Star Warriors!

Most of the leading figures in the scientific community nowadays were Star Warriors with extremely high Life Force levels. The minds of ordinary people simply couldn't handle such immense computational loads.

"Alright, I know some of you might not understand, but I hope you'll make an effort to comprehend it!"

"Teacher, we don't want to become researchers or developers. What's the use of learning all this theoretical stuff?"

Someone couldn't help but complain.

"It may seem useless now, but it will be useful in the future!"

Wu Yuan adjusted his black-rimmed glasses and explained,

"This theoretical knowledge is laying the foundation for your future!"

"This is your last semester of senior high. The Star Exam is only a little over four months away, so let me explain this properly."

"Once you enter a Stellar Academy, your main curriculum will still be Star Warrior courses. However, in addition, you will choose one minor course!"

"Minor course?"

The students blinked, their faces showing interest.

Nearing their college entrance exams, they naturally held great anticipation for their future life at a Stellar Academy...

"Minor courses mainly include [Firearms Science], [Intelligent Mechanics], [Mecha Science], [Starship Science], and so on..."

Wu Yuan continued,

"Without exception, all these courses require a foundation in mathematical theory. If you haven't mastered the theoretical knowledge from middle and high school, you'll be completely lost later on and will quickly fall behind your peers."

"Teacher, are these courses really that important?"

"How to put it..."

Wu Yuan thought for a moment, then said,

"As you know, for a Star Warrior to grow stronger, money is absolutely essential. Whether it's purchasing Star Techniques, various supplements, or potions, it all requires money!"

"The higher a Star Warrior's Life Force level, the more terrifying the amount of resources they consume!"

"If you have family support, that's one thing. But the vast majority of people come from ordinary backgrounds. Your families can't supply you with resources indefinitely, so you'll need to earn them yourselves!"

"And the minor courses I just mentioned are your primary means of making money. Whether it's mechas, starships, combat robots, and so on, they are all extremely lucrative industries. If you show exceptional talent in any of these fields, the amount of money you can earn will far exceed your imagination!"

Upon hearing this, everyone's eyes instantly lit up.

Since becoming Star Warriors, they had deeply understood the importance of money. After all, not everyone could have a family background like Lu Xiaobai's...

"Although they are minor courses at the Stellar Academy, to a certain extent, they determine how far you can go on the path of a Star Warrior!"

Wu Yuan said with a smile,

"Now do you understand the importance of mathematical theory?"

Everyone nodded and began to study diligently.

Even if they couldn't go far on the Star Warrior path, mastering any one of these minor courses could secure them a high-paying job in the future!

Seeing everyone so pumped up, Wu Yuan nodded with satisfaction.

Meanwhile, down below, Lu Xiaobai was also filled with interest.

He understood clearly that these minor courses were essentially similar to special skills like [Basic Scrap Recycling] or [Potioneering].

As long as he could gain a basic grasp, he could use his special advantage to continuously improve them...

"Looks like the Lu family's business won't be limited to potions in the future?"

Lu Xiaobai chuckled inwardly.

If he could master all these special skills and raise them to their maximum level, the Lu family could expand into other industries!

And he himself would probably become the most badass human ever...

After all, a person's energy is limited. No one can master every single special skill.

Three hours later,

A bell rang, marking the end of the math class.

"Using your brain is really exhausting..."

"With our low Life Force levels, it's bound to be tiring. Look at those top students; they all look perfectly relaxed."

The students began to relax. Some left the classroom, others stayed at their desks fiddling with their chip devices to browse the network.

Lu Xiaobai rubbed his temples, a hint of fatigue also in his eyes.

Although his Life Force level had improved slightly, forcing himself to absorb such complex knowledge was still quite a strain.

Just then,

His gaze shifted. He saw Du An leaving the classroom, apparently heading to the restroom.

Lu Xiaobai picked up his backpack and quickly followed.

He hadn't forgotten his main objective. He absolutely had to secure first place in the class assessment for those precious Star Points!

Soon,

Lu Xiaobai trailed Du An all the way to the restroom at the end of the corridor.

"The restroom is a perfect spot!"

He grinned, strode right in, and immediately spotted Du An at the urinal. He promptly moved closer.

"Lu... Lu Xiaobai?"

Du An suddenly jolted, sensing a gaze upon him. He turned his head and saw Lu Xiaobai approaching.

"Heh heh..."

Lu Xiaobai gave a slight smile, glanced around, and felt there were a bit too many people present. He wasn't in a hurry to state his purpose.

However, that very smile of his instantly made Du An's scalp tingle.

Bro, if you have something to say, just say it. Please don't smile like that...

Lu Xiaobai didn't say anything more. Instead, he turned and walked to a stall at the far end of the restroom.

Seeing this, Du An breathed a sigh of relief and hurriedly hitched up his pants, ready to turn and leave.

But at that very moment,

from inside the stall, Lu Xiaobai said in a low voice:

"Old Du, come in here for a second. I've got something to show you."
