"The Power Laws of this world?" Yang Fei’s eyes lit up, and his heart pounded wildly.

It sounded pretty impressive.

"Indeed. Every realm has its own power laws. Once you comprehend the power rules of this realm, you become an invincible existence. It’s akin to the understanding of laws by those at the Nascent Soul Stage and Divinity Transformation Realm," Li Er’s voice said.

Yang Fei grasped this immediately and said, "Master, I understand. As long as I comprehend the Power Laws of the Earth World, I’ll be able to manipulate everything at will within this world, becoming an invincible existence."

"Precisely. This Earth was originally a world I created years ago. In actuality, it was initially just an Extreme Fire Demon Pearl birthed at the Chaotic Beginning."

"Extreme Fire Demon Pearl?" Yang Fei’s mouth twitched. "The name sounds formidable, but why is it later called Earth?"

"Hmph, the so-called Earth is just a name given by secular people who developed their technology to a certain extent in this world. In reality, it is the Extreme Fire Demon Pearl."

Yang Fei felt that Li Er wouldn’t deceive him about such matters.

Besides, Earth is merely a name. If he preferred, he could call it Sky Ball, Fireball, Water Ball, Basketball—nothing would be amiss.

Since Li Er liked to call it the Extreme Fire Demon Pearl, then it was the Extreme Fire Demon Pearl. What difference does it make from calling it Earth?

"Hmph, do you think I casually named it the Extreme Fire Demon Pearl?" Li Er snorted lightly.

Yang Fei let out an awkward smile. He almost forgot that in front of Li Er, he had no secrets, and every thought of his was within Li Er’s perception.

"Master, why call it the Extreme Fire Demon Pearl?" Yang Fei asked understandingly.

Li Er said, "Because when it was first discovered, it was a pearl filled with terrifying flame energy."

Yang Fei uttered an ’oh’, and with some curiosity, asked, "If even Master considers its contained flame energy terrifying, then it must be incredibly powerful. But why is there no fire now, and instead water covers it?"

"Haha, that’s because I spent three thousand years taming it and finally transforming it into its current state," Li Er’s voice carried a hint of pride.

Yang Fei felt nothing.

He hadn’t witnessed the previous state of the ’Extreme Fire Demon Pearl’, so he couldn’t appreciate the effort Li Er had put into transforming it into its current Earth form.

Li Er could sense Yang Fei’s calm demeanor and immediately snorted, "You simply don’t know the reputation and status of the Extreme Fire Demon Pearl in the Cultivation World back then."

He paused for a moment and continued, "Forget it, even in the current Cultivation World, there are likely few who know about the Extreme Fire Demon Pearl. As for its mysteries, you’ll come to understand everything as you comprehend the Power Laws of this realm."

Yang Fei couldn’t help but say, "Master, could you just tell me about this Extreme Fire Demon Pearl?"

"I don’t have the time to talk about useless matters now. Your second arrival here triggered the Primordial Spirit Remnant Thought I left behind, allowing it to awaken. The primary goal now is to help you comprehend the Power Laws of this realm. If you truly are chosen by destiny, we shall meet again."

Upon hearing this, Yang Fei’s heart finally harbored a strange emotion—a sense of deep gratitude from the soul toward Li Er, whom he had never met in person, but who had significantly aided him, allowing him to become stronger through his teachings.

Only at this moment did Yang Fei truly see Li Er as a mentor, akin to Huang Chengcheng.

After all, Huang Chengcheng was someone Yang Fei had interacted with in reality, an esteemed teacher who had patiently taught him everything.

To Yang Fei, though Li Er had granted him a more powerful heritage than Huang Chengcheng, Li Er hadn’t genuinely appeared in his reality—more like a dream.

But with his second visit to this world constructed by Li Er’s remnant soul, again receiving Li Er’s heritage and teachings, Yang Fei’s heart was moved by the gratitude induced by such mentorship, fostering a deep master-disciple bond.

Afterward, it was as if Li Er had completely vanished, with no more voices transmitted to Yang Fei.

Yang Fei found the entire cave world incredibly serene, the dancing golden inscriptions on the cave walls disappearing unknowingly.

It appeared to be an ordinary dark cave.

However, sitting quietly within this cave, Yang Fei felt an unparalleled sense of peace and solidity.

Yet, this comforting sensation was short-lived, for Yang Fei suddenly felt the entire cave brewing with turbulence.

No.

This wasn’t wind.

It was the power elements within the cave surging.

As these power elements surged, they combined and separated, sometimes merging together and at times dispersing, reforming in entirely different configurations than before. 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

Yang Fei immediately understood.

This was Li Er using Divine Power Means to vividly demonstrate the Power Laws to him.

Yet, this was overly vivid.

He felt he could clearly perceive every movement of each power atom; he could precisely capture the existence of every grain among those power elements.

Incredibly magical and strong.

Yang Fei knew that this wasn’t his own ability, but rather a Great Divine Power left by Li Er within the cave, forcibly enhancing his perception of the power elements, allowing him to comprehend the essence of such power rules intensely.

Typically, it’s said the mentor guides you, but the cultivation relies on oneself.

In Li Er’s case, he was using Divine Power Means to forcibly instill skills into him.

That’s what you call a great master producing great disciples.

While feeling touched, Yang Fei also tried to calm himself, immersing completely in sensing the surrounding power elements engaging in various combinations and movements.

Meanwhile, in another cave, the walls were filled with densely packed, jumping golden inscriptions.

Qin Yanyang looked at these symbols with an intoxicated expression.

Each symbol seemed to harbor a piece of the Great Dao, and together, they appeared to form mystic means to connect with Heaven and Earth Power.

Similar to the heritage she received last time in this cave, the Dao rhythm contained in these golden inscriptions seemed like an upgraded version of that previous heritage.

Qin Yanyang, fearing those inscriptions might disappear, desperately wanted to memorize every word, wholly entranced.

Unbeknownst to Yang Fei and Qin Yanyang, since entering the interior of the Nine-Nine Returning to One Array in the White Jade City, time outside had swiftly passed, and five years vanished in the blink of an eye, soon arriving at another workshop trading day.
