Artificial Spiritual Root!

Considering his image in the Chat Group, Lin Yu made a small adjustment to his appearance before sending out the invitation.

After all, his previous face had been too youthful, easily leading to misunderstandings. For that reason, he modified his looks to be more mature.

Thus, when Yun Ye and Su Haoming arrived in this world, what they saw was a Handsome Youth around twenty-seven or twenty-eight years old.

Su Haoming looked at Lin Yu's face with some surprise and couldn't help saying, "Brother Lin, you're younger than I imagined!"

Lin Yu raised an eyebrow and asked with a smile, "Let me guess—you didn't think I'd be a Whitebeard Old Man, did you?"

"...Heh heh!"

Su Haoming looked a bit embarrassed, rubbing his nose as he said, "When you talk about a mage who's lived a long time, it's hard not to picture that kind of image, right?"

Yun Ye laughed. "Given the abilities Brother Lin has shown, preserving youth forever is just the basics. Maybe what we're seeing now isn't even Brother Lin's true form!"

Pretty close guess!

Lin Yu glanced at him, then said with a smile, "Immortality is nothing special. With the Chat Group around, you two will achieve it sooner or later too."

"Compared to that, what's urgent right now is the matter at hand. Do you want to start immediately, or take a tour of my Castle first?"

At these words, Su Haoming's face lit up with amazement. "Brother Lin, this is your Castle?"

Lin Yu nodded. "Mm. My identity in this world is a minor lord in a border region. I built the Castle mainly to fit the aesthetics and worldview of this era..."

"I see!"

Su Haoming and Yun Ye exchanged a glance.

After a moment of hesitation, Yun Ye spoke up. "Brother Lin, the Cross-border Invitation Letter only lets us stay in this world for twenty-four hours, so we'd better get down to business!"

"Right!"

Su Haoming nodded beside him. He felt the same way.

Though he really wanted to explore the Castle, the countdown floating in his mind was a constant reminder not to waste time.

That's perfect!

A smile spread across Lin Yu's face.

He waved his hand, and two thick leather-bound books flew out from the bookshelf beside him, landing in their hands.

"This is the first edition of the Primordial Qi Cultivation Chapter. It details the cultivation method thoroughly."

"...This thick?"

Su Haoming and Yun Ye were both stunned.

Lin Yu laughed. "Don't worry. The Introductory Chapter is only the first three pages, and with me guiding you on the side, I guarantee you'll learn it quickly!"

Hearing this, the two of them finally relaxed.

"Oh, right—before we officially start, I need to test your Magic Aptitude."

"..."

Su Haoming and Yun Ye were both taken aback, then excitedly asked, "Is it tested with one of those magic crystal balls from anime?"

Lin Yu looked at him in surprise and shook his head. "No need for something that troublesome. That thing was phased out ages ago!"

"Of course, if you want to experience it, I could make one on the spot..."

Su Haoming said sheepishly, "Let's just forget it."

Lin Yu said no more. He raised his hand, and a soft white light bloomed from his palm.

The white light instantly enveloped the two of them, making them feel as if they were standing under the sun, warm all over.

"Mmm... feels nice!"

They closed their eyes, somewhat enjoying it.

But before three seconds of comfort had passed, the warm white light vanished completely.

Su Haoming and Yun Ye opened their eyes, looking at Lin Yu with full anticipation, as if asking how it went.

Lin Yu nodded. "As expected. Neither of you has even a shred of Magic Aptitude."

"...Huh?"

Both of them looked disappointed.

Lin Yu smiled. "Don't worry. I've already prepared for this!"

With that, he flipped his right hand, and two shimmering Heptagons appeared in his palm.

"What are these?"

"Spiritual Roots!"

Lin Yu said with a confident expression.

Su Haoming and Yun Ye both froze.

Lin Yu explained with a light laugh, "To be honest, even before joining the Chat Group, I had similar ideas. But back then, I had limited information and my research on the human meridian system wasn't deep enough."

"It wasn't until I joined the Chat Group that my research finally made a qualitative breakthrough!"

"This is one of my research results—an Artificial Spiritual Root!"

"I constructed it based on the Yin-Yang Five Elements Theory, using a Composite Element Matrix."

"Inside, there are a total of forty-nine Element Rune Matrices. Every seven Rune Matrices correspond to one elemental spiritual root. Seven times seven makes forty-nine Rune Matrices, each corresponding to the seven basic elemental spiritual roots of Yin, Yang, and the Five Elements."

"These seven basic elemental spiritual roots can also combine and transform with each other, giving rise to many composite variant spiritual roots like Wind, Lightning, Light, and Darkness."

"Beyond that, the spiritual root itself possesses a certain degree of activity. It can detect the host's spiritual power nature and select the corresponding combination based on the magic affinity of that spiritual power..."

"I won't go into the specific matrix reaction principles—anyway, you wouldn't understand even if I explained."

"All you need to know is that after implanting this thing into your Dantian Qi Sea, you'll have the qualifications for cultivation!"

Having said all that in one breath, Lin Yu looked at the two with a smile, as if waiting for their response.

Su Haoming and Yun Ye exchanged glances and sincerely praised, "Impressive!"

Yun Ye exclaimed in awe, "It's only been a few days, and Brother Lin has already researched this far?"

Receiving rare praise and compliments, Lin Yu showed a satisfied smile.

He turned to Yun Ye and replied with a grin, "Yun Ye, have you forgotten? My world has a time flow rate over a thousand times faster than yours!"

"After Xiao Su told me about the magic power drain, I turned off the chat group and started targeted research."

"To you, Xiao Su's raid on the Ghost Market was just a short while ago, but to me, a whole month has already passed!"

"I see." Su Haoming sighed, "This time flow difference is pretty convenient..."

"Only convenient for us." Yun Ye shook his head, "For Brother Lin, he actually spent a solid month researching."

Su Haoming paused briefly, then said guiltily, "I was wrong to think that way. Thank you for your hard work, Brother Lin!"

Lin Yu, however, didn't mind. To him, researching the magic and cultivation systems was the greatest entertainment in itself.

He chuckled, held up two floating heptagons, and casually snapped his fingers.

In an instant, the surrounding scene underwent a drastic transformation.

The study, once piled high with Magic Books, turned into a spacious and bright laboratory in the blink of an eye.

The lab was filled with many magical instruments, and at its center stood a hexagonal platform five meters wide, inlaid with countless pure gems of every color.

The multicolored magic gems radiated brilliance, weaving together at the edges into a shimmering magic barrier.

"What is this?"

Su Haoming and Yun Ye looked at the platform with curiosity.

Lin Yu smiled. "I call it the Element Reaction Furnace, but to you, it should be considered a Spiritual Root Implanter."

"Alright, no more chatter. First, memorize the Introductory Chapter's cultivation method here. Once you've got it down, let me know, and I'll help implant the spiritual roots into your Dantian Qi Sea."

So it's finally starting?

This path of transcendence from zero!

Su Haoming and Yun Ye exchanged a glance.

The two each found a place to sit down and seriously began reading the cultivation manuals in their hands.

About ten minutes later, Su Haoming stood up first, looked at Lin Yu seriously, and said, "Brother Lin, I'm ready!"

Lin Yu was a bit surprised—he'd thought Yun Ye would be faster!

Well, Su Haoming had been transmigrated for twenty years after all. Twenty years of hard study, even passing the prefectural and county imperial examinations and obtaining a Jie Certificate, earning him the title of Scholar Su from others.

From that perspective, his memory and understanding of traditional national studies were quite good.

It wasn't strange that he'd be a bit faster than Yun Ye...

"Then let's begin!"

Lin Yu waved his hand and handed one of the floating heptagons to Su Haoming.

Su Haoming caught the heptagon, took a deep breath, and slowly stepped onto the three-tiered staircase before the platform.
