Xiao Fei killed the demon dragon and dissected its corpse in the space.
He discovered that after the demon dragon's body was drained by "Blood Devourer," it had little value left.
The demon dragon's flesh and skin resembled weathered wood chips, and its once hard bones would shatter with a gentle squeeze of the hand.
"What a pity!"
However, it wasn't a complete loss. He found many treasures unique to the demon realm in the storage bag the demon dragon carried.
Demon realm cultivators used a type of demon crystal, which contained dense demonic energy, similar in function to spirit stones in the immortal cultivation world.
Xiao Fei had obtained many such demon crystals before. He had once tried throwing demon crystals into his space.
The space could absorb demon crystals just as it absorbed spirit stones.
However, the time flow in his space now required an additional point for 10 billion spirit stones. The amount of demon crystals he had was far from enough.
The two to three hundred million demon crystals obtained from the demon dragon could only be kept for now.
Additionally, Xiao Fei found a dark, lustrous pill on the demon dragon. This pill was pitch-black and shiny, containing dense demonic energy, and it was an upper-grade pill.
Although Xiao Fei could often refine upper-grade pills himself, in his many years of navigating the immortal cultivation world, he had rarely seen anyone else able to refine upper-grade pills.
With his current mastery of pills, he quickly determined that this pill could cure his "Crimson Face White Bone" poison.
Furthermore, the detoxifying effect of this pill was much stronger than the Upper-Grade Grand Void Soul Cleansing Pill he had refined himself.
Xiao Fei carefully stored this pill separately. If he had the chance in the future, he would definitely obtain the pill formula.
After dealing with the demon dragon's corpse, Xiao Fei personally went to inspect the damaged Demon Sealing Well.
He repaired the damaged formations and then distributed the remaining "Crimson Face White Bone" poison into the 36 Demon Sealing Wells.
The poison would naturally become more potent with increased toxicity.
The upper-grade detoxification pills of the demon race were likely not numerous.
Now, it was a competition to see who had more poison or more detoxification pills.
In another 100 years, "Crimson Face White Bone" would begin its next cycle of blooming, and its toxicity would be even stronger.
Xiao Fei burned the demon dragon's corpse and then checked on the "Crimson Face White Bone," spreading demon corpses on the ground as fertilizer.
Just then, Xiao Fei's mind stirred, and he walked towards the center of his space.
A vine grew there, producing one leaf every ten years. He had once suspected it was a Heaven and Earth Spiritual Root.
This vine had been growing in his space for tens of thousands of years, yet it had still not flowered or borne fruit.
But today, Xiao Fei suddenly noticed a small flower bud appearing on the vine.
This small bud had not yet unfurled. It was tightly wrapped by green leaves, with hints of white petals peeking out from within.
He leaned closer and sniffed, but he couldn't detect any fragrance.
After waiting for so many years, seeing it finally grow a flower bud was, after all, a good thing.
However, for such a long vine to grow for tens of thousands of years and only produce one flower, its yield was clearly quite low.
Xiao Fei had been back on the Eastern Continent for 50 years. In another 10 years, the natural formation could be activated again.
This place was not suitable for cultivators above the Nascent Soul stage to cultivate. At that time, Xiao Fei would lead Huang Feifei and others to leave the Eastern Continent and head to the Tian Yuan Realm.
However, the demon race might still come through the inter-realm passage in the future, which made him uneasy.
Therefore, before departing, Xiao Fei specifically visited the valley where "Blood Devourer" resided again.
The two discussed matters in secret in the valley for a day. It was unknown what they did or what conditions they agreed upon.
In any case, after leaving the valley, Xiao Fei confidently led his four Nascent Soul subordinates and flew towards the East Sea.
...
"Wow! The spiritual energy here is so dense!"
"Cough, cough, cough..."
"I'm choking!"
For the first time experiencing the dense spiritual energy of the Tian Yuan Realm, all four were unceremoniously choked by it.
"I've lived for over 1,000 years, and I've never encountered such dense spiritual energy!"
Ji Wudi smoothed his breath and exclaimed.
The other three felt the same, but they didn't voice it. At this moment, they were all greedily inhaling.
They wished they could breathe in without ever exhaling!
"Follow me. This is just the edge of the Tian Yuan Realm; the spiritual energy isn't particularly dense!"
Xiao Fei led the four of them cautiously through the territory of the Western Sea demon race and bypassed the human islands.
Finally, they set foot on the land of the Central Continent once more.
Xiao Fei had caused some trouble in Guiyi City last time. He didn't know the outcome of those matters yet and didn't dare to go there rashly.
He felt a pang of sadness remembering that the Jiang family had been annihilated because of him.
Although the Tian Yuan Continent had denser spiritual energy and was more suitable for cultivation, it also had more powerful cultivators and greater risks. A slight misstep could lead to a fatal disaster.
"Little brother, I want to travel around and see things on my own from now on, so I won't be accompanying you!"
Xiao Lan patted Xiao Fei's shoulder, about to leave.
Although she could now form a physical body using blood threads, she was still different from humans and might bring unnecessary trouble to Xiao Fei.
Rather than being a burden, she preferred to venture out on her own.
"Feifei, I'm entrusting my little brother to your care!"
"Little brother, you're not a child anymore. Be good to Feifei!"
After giving them a few instructions, Xiao Lan's body suddenly collapsed, transforming into countless blood threads that seeped into the ground.
Xiao Fei wanted to speak to persuade her to stay, but by then, Xiao Lan's trace was nowhere to be found.
Ghost cultivators might not have the strongest direct combat power, but their strangeness and elusiveness always made them hard to track.
"We should be going too!"
"We also want to travel and gain some experience on the Central Continent."
At this moment, Zhu Yu and Ji Wudi also came to bid farewell to Xiao Fei.
They could not be dependent on Xiao Fei. Cultivators were meant to venture out and seek their own opportunities.
Xiao Fei watched the backs of Zhu Yu and Ji Wudi as they walked side-by-side into the sunset and gradually disappeared from his sight.
For the first time in his life, he realized that Zhu Yu and Ji Wudi walking side-by-side actually looked quite harmonious.
At this moment, only he and Huang Feifei remained.
"Feifei, let's go too!"
"Mm! Okay!"
Xiao Fei took out a map and checked it.
"Let's go to Tiantong City!"
Tiantong City was larger than Guiyi City and had more powerful cultivators.
Similarly, the spiritual energy was denser, and there were more heavenly materials and earthly treasures.
Legend had it that in the ancient past, there was a Tongtian Jianmu tree in Tiantong City.
Cultivators could reach the immortal realm by climbing this Tongtian Jianmu tree.
Of course, this was just a legend.
Perhaps such a Jianmu tree once existed, but now, not even its roots could be found.
However, this ancient cultivation city had remained, and it was still a major cultivation city on the Central Continent.
