Xiao Fei collected the Ten Thousand Year Immortal Marrow Liquid from the groove into a jade bottle and sealed it.
After securing the Immortal Marrow Liquid, Xiao Fei surveyed the cave thoroughly.
The large pillar in the center of the secret chamber was entirely composed of Immortal Stone Marrow. For every ten thousand years that passed, the Immortal Stone Marrow would produce a drop of Immortal Marrow Liquid, hence its name.
Xiao Fei pondered whether he could move this pillar of Immortal Stone Marrow into his space.
With one drop produced every ten thousand years, its output would significantly increase if placed within his space.
Furthermore, it was a waste of such a treasure to leave it here unattended.
He had been examining it with his immortal sense, and the Immortal Stone Marrow pillar was tightly connected to the local ley lines. Simply moving the pillar alone would be useless.
It was necessary to move a large area, or even the entire Immortal Stone Marrow vein, into his space for the stone pillar to continue producing Immortal Marrow Liquid.
This task was somewhat difficult, but not insurmountable for Xiao Fei at his current level.
At this moment, a branch appeared in his hand, with an egg-sized fruit hanging from its tip.
With a thought from Xiao Fei, the fruit rapidly enlarged, transforming into a small world that enveloped a vast surrounding area.
Immediately after, the small world merged with the mine where Xiao Fei stood.
After a moment, Xiao Fei waved his hand, and the small world shrank, reverting to a fruit hanging from the branch.
However, the large area where Xiao Fei had been standing had vanished.
The secret chamber was gone, the mine was gone, and even the ley lines and mineral veins of this region had disappeared.
The commotion here had already alerted other treasure hunters in the vicinity.
Several figures immediately flew over, witnessing a large area vanish into thin air, replaced by a pit tens of miles in diameter.
At the bottom of the pit stood an unremarkable man, looking around.
It was evident that some extraordinary treasure had appeared here and had been obtained by this individual.
"May I inquire what treasure this fellow Daoist has obtained? Could you allow us to have a glimpse?"
These treasure-hunting cultivators, their eyes filled with greed, gradually drew closer, surrounding him.
Xiao Fei glanced at the treasure hunters with ill intentions.
There were thirty-two in total, with only one at the True Immortal realm, and the rest were Earth Immortals.
Not a single one posed a challenge!
"Indeed, there is a treasure. If you are all interested, it wouldn't hurt to observe it together."
As Xiao Fei spoke, a branch appeared in his hand, its fruit a vibrant green, exuding a dense immortal aura.
"Ah! It's an Immortal Artifact! Retreat quickly!"
All thirty-two individuals were discerning and, upon seeing Xiao Fei produce an Immortal Artifact, their faces changed dramatically, and they scrambled to flee backward.
"Fellow Daoist, let's talk this through, let's talk this through!"
"We were merely curious to see. If you are unwilling, we shall depart. Why harm our harmony over such a trivial matter!"
These treasure-hunting cultivators were all impoverished, many being mere rogue immortals who couldn't even muster a decent weapon from their possessions.
Now, seeing Xiao Fei wield an Immortal Artifact, they had no courage to oppose him.
Xiao Fei had no intention of pursuing further. He retracted the Immortal Artifact from his hand, and with a flash, he vanished, reappearing tens of miles away in the next instant.
It seemed the map given to him by Zhu Yu was quite useful; the first stop indicated on the map had successfully yielded a treasure.
Following the map's directions, he then located the ruins of a medicinal garden belonging to the Haoyu Sacred Land.
This place had also been thoroughly ransacked multiple times. Not to mention immortal herbs, not even a root or a leaf would be left behind.
When Xiao Fei arrived, two rogue immortals were taking turns with shovels, digging a large pit in the ground.
Within these ruins, there were quite a few such pits of various sizes, all dug by immortals who had come here to seek treasures.
"Hahaha... As expected, I wasn't mistaken. We've truly found a residual immortal root."
"Indeed, this is the root of an Immortal Crane Grass. Although much of its immortal energy has dissipated, it can still fetch six or seven immortal stones."
The two admired the immortal root, their hearts filled with excitement, so much so that they didn't even notice Xiao Fei approaching.
Looking up, they suddenly saw an ugly-looking man staring at them. A chill ran down their spines, and they quickly put away the immortal root in their hands, watching Xiao Fei with vigilance.
"Fellow Daoists, do not be alarmed. I bear no ill will."
Xiao Fei quickly reassured them. Possessing millions of immortal stones, he found it difficult to muster interest in items worth only a few immortal stones.
However, the two did not fully trust his words and remained wary, having encountered many duplicitous individuals.
Xiao Fei, too lazy to explain further, flew directly towards their location.
This greatly startled the two rogue immortals, who immediately unleashed their great divine abilities to protect themselves.
As expected, he was a treacherous individual, his ultimate goal being the immortal root they had just obtained.
As Xiao Fei drew closer, the two felt a wave of despair; the opponent's strength was too great for them to possibly contend with.
At that moment, a tremendous force was exerted upon them, simultaneously immobilizing them.
"We're finished!"
"Tens of thousands of years of cultivation, ruined in an instant."
However, just as despair set in, the dreaded outcome did not occur. Xiao Fei casually tossed them tens of miles away and paid them no further mind.
The two rogue immortals sat on the ground, their minds in a daze for a long time before they could react.
Having narrowly escaped death, they first felt for the immortal root, finding it still there.
Then, they checked their bodies; every part was accounted for.
"Hoo..."
"To survive a great disaster is to gain great fortune!"
The two were surprised that someone genuinely had no interest in treasures.
If that person had made a move just now, they would certainly not have been able to keep their immortal root, a treasure worth several immortal stones.
When they looked back, they found that Xiao Fei had already vanished.
At this moment, Xiao Fei had appeared within a secret realm.
This was a dimensional space created by a powerful being using great divine abilities, and it was impossible to discover without special means.
This dimensional space had been personally created by Zhu Yu, with its entrance located precisely where the two rogue immortals had dug out the immortal root.
Using the activation rune given to him by Zhu Yu, he easily entered this secret realm specifically for cultivating immortal herbs.
This secret realm contained some rare immortal herbs, which had fortunately not been damaged over the years.
However, due to the long period of neglect and the dissipation of immortal energy, most of the immortal herbs had died.
The few immortal herbs that managed to survive looked sickly, listless, and half-dead.
Xiao Fei examined them one by one, and with each one he saw, his heart ached.
These immortal herbs were of extremely rare varieties, seldom seen even with immortal stones.
They were far superior to the common varieties in his space.
Within this realm, there were at least hundreds of varieties, totaling over ten thousand plants, but sadly, the vast majority had perished.
