The spiritual energy in the space's prison had been quite abundant recently. Even more rare was that Xiao Fei had not added any poison to the spiritual energy.
Having absorbed sufficient spiritual energy, the One-Horned Demon Clan's strength had recovered substantially.
Today, Xiao Fei reappeared in the prison, and the One-Horned Demon Clan immediately lunged at him.
Fighting Xiao Fei now was akin to defeating a monster for loot. Every time he won, although he couldn't kill Xiao Fei, he would always obtain a bottle of pills or a demon crystal.
This positive reinforcement made the One-Horned Demon Clan eager for more.
Conversely, when Xiao Fei was absent, he felt bored and missed their encounters.
Seeing the One-Horned Demon Clan charge, Xiao Fei nimbly dodged to the side, easily evading the attack.
After prolonged practice, coupled with his rising cultivation, he could now battle the One-Horned Demon Clan for one to two hours without necessarily being defeated.
An hour later, as Xiao Fei dodged a full-power strike from the One-Horned Demon Clan, his black saber slashed diagonally.
"Boom!"
An arm of the One-Horned Demon Clan fell to the ground!
This was Xiao Fei's first victory since their battles began.
"Trash!"
Xiao Fei sneered contemptuously and then left the prison.
In the prison, the One-Horned Demon Clan, holding its severed arm, felt a mix of emotions. This brat's progress was too rapid.
Had his purpose in crossing realms been to serve as a whetstone for others?
With this thought, malevolent intentions arose in his heart. Next time, he would strike with all his might, aiming for a killing blow.
The Dragon Blood Lychees in the space had ripened again.
Furthermore, he had planted a few more seeds last time, and now there was a small orchard of Dragon Blood Lychees.
This time, there were more fruits ripe, allowing him to indulge freely.
Dragon Blood Lychees tasted exquisite and were of great benefit to body-refining cultivators.
Xiao Fei picked a few of the largest ones from the trees and brought them out of the space.
He was currently in a secret chamber of a flying giant boat. The moment the Dragon Blood Lychees were brought out of the space, their emitted fragrance permeated the entire flying boat, passing through the secret chamber.
The thousands of cultivators on the flying boat, affected by the aroma, all stretched out their noses, trying to locate its source.
The scent was incredibly enticing, awakening their most primal appetites. Their mouths watered uncontrollably.
Fortunately, Xiao Fei was not someone who ate noisily. He immediately set up a formation in the secret chamber, preventing the scent from escaping any further.
Only then did he pick up a Dragon Blood Lychee and begin to peel and eat it.
After consuming one, a warm current surged through his abdomen, rapidly spreading to all his limbs and bones.
But this was not enough. He immediately peeled another crystal-clear Dragon Blood Lychee and bit into it.
After eating several Dragon Blood Lychees in succession, Xiao Fei's internal power became surging and mighty. He then took out an egg-sized mid-grade pill and swallowed it...
Ten days later, Xiao Fei stood up in the secret chamber, stretching his limbs and feeling the surging power within him, immensely satisfied.
With this, he had officially cultivated the "Wind Thunder Battle Body" to the third level. His magical power and physical strength had both reached the late Nascent Soul stage.
These two combined had increased his strength severalfold.
Xiao Fei walked out of the secret chamber. The flying boat was currently docked in a forest, temporarily recuperating.
Meteor Island now possessed two flying giant boats, but the consumption of spirit stones was too high.
In the past, they could still sell some special spiritual items from the East Sea to the Eastern Continent, earning spirit stones through peaceful trade.
However, most of the Eastern Continent was now demon territory, and doing business with them to earn spirit stones was impossible.
As the saying goes, when goods cannot cross borders, soldiers will.
This time, Xiao Fei and Huang Feifei jointly organized a group of personnel to pilot this flying boat and quietly fly out from Meteor Island. Their primary objective was to go into demon territory to acquire spirit stones.
The demons had conquered many factions, and the spirit stones accumulated by these factions had fallen into the hands of the demons.
Furthermore, there were many spirit stone mines in the demon territory, which the demons had not stopped exploiting after occupying them.
In addition to this, Xiao Fei also intended to see if he could fight a Nascent Soul stage demon head-on if he encountered one again during this trip.
Xiao Fei walked through the internal corridors of the flying boat. Cultivators coming and going greeted him enthusiastically.
His reputation on Meteor Island had finally caught up to Huang Feifei's.
Especially after Xiao Fei, at the late Nascent Soul stage, had withstood the attack of a Soul Transformation stage Bone Spike Demon, and it was rumored that the Soul Transformation stage demon had even fled in the end.
After these news spread, Xiao Fei was regarded not only on Meteor Island but throughout the entire human race as the hope for humanity's future.
Under the relentless advance of the demons, the Eastern Continent had gradually fallen. Most humans were now in despair, seeing no hope.
The meager resistance that could be organized relied solely on an unyielding spirit of bravery.
Therefore, Xiao Fei's sudden emergence had already made him the most dazzling star of the entire human race.
"Young Master, you are out of seclusion!"
Huang Feifei was the first to notice Xiao Fei emerging from seclusion and approached him to speak.
"Young Master, there is a demon stronghold ahead. According to the intelligence provided by Second Sister, the spirit stones mined from several nearby spirit stone veins are temporarily stored there."
As Huang Feifei spoke to Xiao Fei, she waved her hand, and a map projection appeared in the air before them.
This map, projected using divine sense and magical power, was extremely detailed, showing streets and houses clearly, and could be zoomed in and out.
Huang Feifei pointed to a city on the map.
"It's this place. It was formerly a human city with a population of nearly a million. All the old, weak, sick, and disabled humans within were killed, and the remaining able-bodied men were sent into the mines to extract spirit stones."
"According to the news, the city is only guarded by five Nascent Soul stage demons, with no Soul Transformation stage powerhouses. With the strength of our flying boat, we should be able to take it down easily in one round..."
Huang Feifei explained to Xiao Fei while continuously pointing at locations on the map, displaying great generalship.
"Young Master! Do you think this attack plan needs any additions?"
"This plan is already perfect. I have no objections!"
Xiao Fei knew that because he was on the flying boat, Huang Feifei liked to consult him on all matters, though she already had a clear plan in mind.
The subsequent attack on the demon stronghold did not require Xiao Fei's direct involvement. Under Huang Feifei's command, the stronghold was easily captured.
As expected, a large quantity of spirit stones was found within the stronghold. Additionally, several sub-teams were dispatched to confiscate spirit stones from the surrounding spirit stone mines.
The total amount of spirit stones obtained this time was at least over a hundred million.
After clearing out the supplies of one stronghold, the flying boat immediately transferred the group and flew towards the next demon stronghold.
The demons now occupied most of the Eastern Continent, but relative to the total demon population, they were far from sufficient to control such a vast territory.
Therefore, apart from the front lines where they could mobilize some forces, the rear was riddled with weaknesses and was very fragile, unable to be effectively guarded.
Xiao Fei felt that this situation was most suitable for guerrilla warfare behind enemy lines.
