In another world, Lu Mingfei is learning card making.

"Kamaitachi is a kind of auxiliary Word of Power."

Of course, while rubbing Lu Mingfei's fingers, Jing Shu did not forget her "mission"—to introduce and teach the power of words, "The releaser constructs a large domain with himself as the center, establishes complex sound channels within the domain, and thus controls all the tiny sounds within the domain."

"Just like now, even if you just raised your hand, I could sense your movement through the sound of your elbow bones rubbing together and react accordingly."

"As a supplementary form of incantation, it is quite safe, but there are still two risks: First, if it is kept on for a long time, the perception of sound may become too acute, which can easily lead to insomnia, neurasthenia, or even further induce hallucinations;"

"Secondly, if a loud noise occurs within the Kamaitachi's territory, it will cause serious and severe damage to the ears and brain structure of the person who releases it."

"Of course, for us dragons, these negative effects can be avoided—we just need to shut down the Kamaitachi."

Lu Mingfei listened quietly to her introduction, then imitated her actions and called out:

"Word of Power: Kamaitachi!"

Unfortunately, nothing happened.

Lu Mingfei looked to Jing Shu for help. Undoubtedly, since Jing Shu could use it, it meant the incantation was effective—so why couldn't Lu Mingfei use it himself?

Jing Shu pondered for a moment, then raised her hand to hold Lu Mingfei down and instructed, "My lord, please do not resist what is happening inside your body."

"I need to know what happened to you, as it might trigger your spiritual vision."

After Lu Mingfei nodded, Jing Shu took a deep breath and began to chant, her warm breath brushing against Lu Mingfei's nose, bringing a fragrance reminiscent of musk:

"[Praise be to our King's awakening! Destruction is rebirth!]"

Lu Mingfei could feel Jing Shu's hand pressing on his shoulder tighten, and her golden pupils gradually turned bloodshot, like the fiery clouds enveloping the sun at sunset—

Unfortunately, Lu Mingfei felt that his reaction was very unworthy of her serious concern.

He simply thought Jing Shu's voice was very pleasant, melodious and beautiful, like singing—if he had to say something else, it would probably be that her scent was just as pleasant...

"Um, is it over?" Feeling his shoulder being squeezed painfully, Lu Mingfei quickly interrupted.

He didn't want to end up in the school hospital because of "his own magical spirit breaking his shoulder."

"...Don't you feel anything?"

Clearly, this was completely beyond Jing Shu's expectations—

"It shouldn't be like this. Any heir of the Black King should respond to these words—this is a symbol of the Black King's authority, His first cry and His last cry..." Jing Shu murmured to herself, her eyes flashing with increasingly intense panic.

"If you don't react to it... are you a descendant of the White King? Or... are you not a dragon at all?"

"Isn't it possible that I am the Black King himself?" Lu Mingfei suddenly thought of that dream, the black dragon, the oldest emperor not recorded in history, "Because I said those words, so I didn't react to them... Never mind."

Lu Mingfei quietly pursed his lips.

This kind of story, where seemingly ordinary people are actually reincarnated deities, was something Lu Mingfei hadn't seen before in *Chinese Paladin 3*. Jing Tian was the reincarnation of Tianpeng, and he was accompanied by Long Kui, Xue Jian, Xu Changqing, and others—

But thinking about it, it seemed unlikely. Only family members know their own situation. Lu Mingfei felt that there was definitely no demonic sword possessed by a ghost or any Tang Clan descendant around him.

Jing Shu, on the other hand, quieted down—not just quiet, she even showed a look of sudden realization, her expression becoming more respectful and cautious, as if she really took Lu Mingfei's nonsense as an explanation.

A moment of silence fell between them. Lu Mingfei pondered whether to find another topic to talk about, but the next second, the topic popped up on its own—

Suddenly, the Mirror of Eternity appeared in mid-air, and Louisa stepped out from it.

She looked up at Lu Mingfei and asked, "My master, how long did it take me to make this world jump?"

Lu Mingfei glanced at the timer on his Sorting Card: "About an hour—so, what's the difference in time flow between these two world jumps that you calculated?"

Louisa shook her head. "Master, I need to correct one of your mistakes:"

There is no such thing as a "difference in the flow of time" between different worlds.

"If we compare the world to a river, then the material world is like the flowing water, and time is like the riverbed beneath the surface. Moving from one world to another is essentially stepping from one river to another."

"In my experiment just now, I stayed in another world for an hour, but it took me an instant to come back; I stayed in another world for an instant, but it took me an hour to come back."

"It's not that the two worlds I traveled through were different, it's just a matter of whether I went up or down when crossing the land in the middle of the river."

Lu Mingfei frowned in thought, trying to understand Louisa's metaphor, but Jing Shu quickly grasped what Louisa was describing and retorted:

"According to your description, doesn't that mean we can stay in another world for more than ten years until our strength experiences a breakthrough, and then return in an instant?"

"How can there be such unreasonable things in this world?"

Louise crossed her hands over her abdomen, making the symbol on her chest more prominent, before explaining:

"Yes, that's right. We can stay in another world for more than ten years until our strength increases significantly, but that doesn't mean we can spend an instant to come back."

"Time is the riverbed beneath the world; if we remain stagnant, letting the world change as it may, we will certainly not be swept away by the waters of the world and flow through it."

"But if we try to interfere with the natural development of that world, or try to become stronger there, it's like actively going against the current; of course, we'll be swept away by the river and drift downstream."

"At that time, even if we try our best to trace back to the source, we will certainly not be able to return after leaving for a moment, as I just tried."

"This means that if we want to become powerful in another world, it will likely take much longer than it would take to become powerful in our own world."

Jing Shu wanted to say something more, but Lu Mingfei gently patted the back of her hand, and she instantly understood what Lu Mingfei meant:

Indeed, Louisa's logic may have some flaws, but for Lu Mingfei, what he needs is not a flawless theoretical work of art, but practical logical guidance.

This will affect how he uses the Mirror of Eternity.

"In short, the Mirror of Eternity is indeed usable—so let's use it. Louisa, do you have any good suggestions on this?" Lu Mingfei turned his gaze to Louisa.

She pondered for a moment, then spoke:

"Don't try to cultivate yourself alone; instead, interfere with its free development—this is like gathering the stones that were already in the riverbed together, so that they will move more slowly under the scouring of the river."
