The Lord Demon King is Unfathomable!

Chapter 1239 367: Colin, Shining Like the Sun (Part 3)

They gathered the right materials and began crafting with a clinking sound.

Hard work pays off for those who are determined.

After several failures, they actually managed to make a simple "Reflector Observation Instrument"!

When everyone first clearly saw each hair-thin engraving on the tiny gear, they all exclaimed in surprise and cheer.

At this very moment, they were unaware that apart from seeing the engravings on the gear clearly, they inadvertently accomplished a remarkable feat—

The approach they used to solve the problem was precisely the technical principle behind more precise optical instruments like the reflecting telescope and microscope.

These Magic Apprentices almost created these epoch-making tools!

"Ilana, you are... so smart!" Jamie exclaimed sincerely, "I definitely wouldn't have thought that a lens could be used this way!"

"Yeah, yeah," Lam's face was full of admiration, his cheeks rosy like apples, "I thought we couldn't solve it, but it wasn't as hard as I expected when we actually started working on it..."

Facing her companions' praise, Ilana's slightly cool face unusually showed a hint of embarrassment, and she replied in a soft voice.

"I just happened to recall something our Master taught us. Besides... it's all thanks to everyone's persistence, it's not just my achievement."

After she spoke, she hurried back to her workstation, anxiously continuing the work she had left behind, hiding the blush creeping up her ears.

Watching Ilana's back, Lam's eyes were full of longing, and he couldn't help but softly remark to Jamie next to him, "I didn't expect that Sister Ilana, who seems so cold, could actually get shy too..."

Jamie nodded dumbly but did not speak. The young men standing nearby were the same, their faces turning red involuntarily...

...

The next morning.

When Luo Yan learned that his apprentices had actually managed to create the prototype of a reflecting telescope, he was both shocked and incredibly pleased.

Apart from commending these smart and diligent young people, he immediately established a new project in his laboratory—to encourage his apprentices to design a telescope that can see even further.

This thing has significant uses in both navigation and astronomy; perhaps even the Imperial Royal Navy Academy would take an interest.

In such a case, the school of thought named "Science" might even gain the support of the Imperial Officer Faction, shining even brighter on this desolate snowfield!

However, this is still quite distant for now.

The research on improving the telescope is currently being led by Jamie and Lam, while Ilana remains absorbed in the notes belonging to James Walli.

Incidentally, setting aside her crucial role in inventing the "Reflector Observation Instrument," her progress over the past two months has been nothing short of breathtaking.

Especially after mastering the powerful mathematical tool "Calculus"!

Many of the complex calculations in the notes, which were once obscure and required going in circles to solve, she now handles with ease.

Furthermore, she could even reverse-engineer and use more concise formulas to optimize Mr. James's derivation process, correcting several flaws caused by outdated calculation methods.

However—

Just like Jamie and Lam would encounter their own bottlenecks, when she followed the footsteps of her predecessors to the end of the road, difficulties finally loomed over her head.

Especially as her research gradually delved into domains even Mr. James had not conquered, she felt unprecedented strain.

Every problem she faced lacked the experience of predecessors to draw from, and every exploration felt like a solitary journey through dense fog.

She put down the feather pen in her hand, gently massaging her throbbing temples, her cool face revealing deep fatigue.

And just then, a gentle voice sounded behind her.

"Encountered trouble?"

Ilana turned back in surprise to find Prince Colin standing behind her at an undisclosed time, looking at the sprawling formulas on the table with interest.

"Master..." She said embarrassedly, standing up with a red face and speaking shyly, "Yes, Mr. James encountered an issue with the limit of a multivariable function here. Although you mentioned it in class, you didn't elaborate. I tried it... but I still can't figure it out."

Luo Yan understood and nodded, and after thinking for a moment, he took out a brand new book from his Storage Ring and handed it to her.

This was something Youyou helped him transcribe. As for how it was transcribed, he hadn't inquired, thinking that the Players might have played a role in it.

Ilana took it in confusion, only to see on the cover of the book, several words in Imperial common language she had never seen before—

Advanced Algebra?

Watching Ilana's bewildered face, Luo Yan smiled and said.

"Calculus is just the foundation of Advanced Mathematics; what I've talked about in the classroom is merely superficial, as I have to consider those who can't follow. However, you have an unexpected talent in mathematics, and I think it's time to entrust you with this book... perhaps it can provide you with some assistance."

Upon hearing this, Ilana was momentarily stunned.

Her expression first showed surprise, then excitement and emotion. She reached out with trembling hands, took that heavy book, and held it in her arms.

To her, it was not only new knowledge but a hefty recognition!

Feeling the lingering warmth on the book's cover, Ilana looked up at Prince Colin with unprecedented seriousness and said.

"Master... I will surely take good care of it!"

She swore!

She would dedicate her life to defending her Master's "Science"!

Watching this overly excited Magic Apprentice, Luo Yan chuckled, waved his hand, and signaled her not to be so nervous.

"It's just a book; I have plenty of them. Rather than having it sit on the shelf, I hope you use it until it's worn out."

Pausing here, he switched to a slightly solemn tone and continued.

"... work hard. I hope that after you understand it, you can help me teach it to the other apprentices in the laboratory."

"One day, if I'm not here, you all will have to depend on yourselves to spread the doctrines I've left behind."

The spark of enlightenment has been lit; as to when it can turn into a prairie fire, that depends on the people here and their own fortune.

As the Demon King, all he does is ignite the flame.

But they were very fortunate because Lord Demon King didn't just ignite fires in one place but instead fanned the flames around the world.

When those flames rise into the sky, their era will arrive.

"Hmm!"

Hoping that day will come a bit later...

Tightly holding that "Advanced Algebra" book, Ilana's heart was filled with excitement, reluctance, stirring emotions, and various others.

After hesitating for a long time, she finally couldn't help but voice her biggest question.

"Master, your profound knowledge... where exactly did you learn it from? Was it the Gana Continent? Or the Holy City?"

Rather than following a Mage who had given up on his own doctrines, she actually yearned more to follow in this lord's footsteps!

That kind of longing was like a sunflower's desire to face the sun.

Facing those eyes full of curiosity, admiration, and even a hint of faint longing, Luo Yan did not directly answer.

"I'm not as great as you think."

He turned to look at the Mage Tower standing amidst the clouds outside the window, speaking in a distant and humble voice.

"I'm merely standing on the shoulders of giants."

He had long wanted to say this.

He finally found an opportunity.
