Inside were quite a few Spirit Stones.
There was a scroll of Cultivation Technique, named "Flesh Transmutation Skill."
It was an Evil Path Skill that, after cultivation, would allow one to abandon their natural appearance, transforming their flesh at will and easily shape-shifting.
However, during the process, a Cultivator's self-awareness would gradually become confused.
Eventually, they no longer knew whether they were man or woman, tall or short, fat or thin, and might even forget whether they were "human."
Once the flesh spiraled out of control, it would become twisted and deformed.
They had to drink human blood to maintain human form.
Mo Hua glanced over it a few times, clicking his tongue and shaking his head.
He had originally wanted to learn the "Disguise Technique," but now it seemed that since this Cultivation Technique was so malevolent, he wouldn't be able to learn it.
What if he did learn it, and his parents, master, Junior Brother, and Junior Sister couldn't recognize him in the future?
Moreover, it required drinking human blood...
He would never drink it.
Aside from this "Flesh Transmutation Skill," there were several other Evil Path Skills that, although sinister, weren't particularly special.
In the end, there was a jade slip.
Mo Hua could tell at a glance what it was.
"It's a Letter Token!"
Gu Changhuai's gaze also suddenly sharpened.
The Letter Token, which Jia Ren had not carried on his person and had no idea he was being watched before his misfortune, most likely still had its content intact.
And that Letter Token could very well contain the clue to the whereabouts of the Fire Buddha!
Gu Changhuai focused his gaze on it and his expression suddenly stiffened.
Inside the Letter Token, a vast expanse of white appeared—completely empty of any writing.
"What is this..." Gu Changhuai frowned.
"Is it sealed?" asked Mo Hua from the side.
Looking at Mo Hua, Gu Changhuai said somewhat numbly,
"You wouldn't happen to know how to... unlock seals as well, would you...?"
"I do, actually," Mo Hua nodded, "a bit..."
"How... how does one unlock it?"
When it came to the principles of Formation, Mo Hua became excitable.
He had been researching the unlocking and decoding of seals for a long time, and now he could finally "show off."
"The principle of adding a seal is based on the Magnetic Pattern principles of the Yuan Magnetic Formation..."
"Fixed Magnetic Patterns, through a certain agreement, match Unfixed Magnetic Patterns, and this agreement itself is a kind of magnetic flux. After the magnetic flux circulates, it will generate Secondary Thunder Patterns..."
"So to unlock a seal, one must find the Secondary Thunder Pattern that serves as the Sealing Pattern. By applying the Secondary Thunder Pattern in reverse to the Unfixed Magnetic Patterns, one can dissipate the 'Magnetic Ink Mist,' thus breaking the seal and revealing the hidden words..."
...
Gu Changhuai felt numb listening to it.
He felt that he could understand each word individually, but put together, he was completely lost.
The words spoken by Mo Hua were clear and organized, but utterly perplexing.
All this talk of "magnetic" this and "Pattern" that, was like the magnetic flow—swarming and intricate, entering his left ear and exiting through the right.
He had not memorized anything, his mind like a field covered in heavy snow, blank and utterly bewildered.
"The principle is roughly like that..."
After explaining, Mo Hua asked Gu Changhuai, "Uncle Gu, did you understand...?"
Gu Changhuai paused, then forced himself to assert calmly,
"Mm, I got it..."
In front of Mo Hua, he could only pretend to understand.
Although in reality, he didn't grasp a single bit...
Fearing Mo Hua would continue, Gu Changhuai quickly said,
"Let's not delay, first let's unlock the 'Sealing Pattern' on the jade slip..."
"Catching the Fire Buddha is urgent..."
"Mm, mm," Mo Hua nodded vigorously.
Gu Changhuai, for some reason, felt a silent sigh of relief in his heart.
Then he saw Mo Hua focus intently, looking at the jade slip while continuously drawing some strange and curious Formation Patterns on paper, occasionally mumbling to himself...
"This isn't..."
"Not this..."
"It looks a bit like..."
"Not this..."
...
Mo Hua was utterly focused, with a gleam in his eyes, like the twinkling of stars.
Gu Changhuai's gaze trembled, and he unconsciously slowed his breathing, afraid to disturb Mo Hua.
After an unknown period, a flicker of light crossed Mo Hua's eyes.
"I've unlocked it!"
Gu Changhuai was inwardly shocked and simultaneously somewhat incredulous.
"What does it say inside?"
Mo Hua then immersed his Divine Sense into the jade slip.
Within the jade slip, a vast emptiness held only eight characters:
"Bi Mountain Demon Cavern, Heaven Beyond Cave Heaven."
