"As it has been sealed for far too long, over half of the sinister yin energy within this Netherworld Yin Blade has dissipated, severely diminishing its power,"
Ye Yunfei’s Soul Power probed and studied within the black long blade. "It seems I'll need to feed it a lot more yin and evil energy in the future..."
Just then.
"Hmm?"
"This Netherworld Yin Blade actually has a sinister secret art sealed within it! It's called the Nine Heavens Ten Earths Nether Confinement Art!"
A flicker of excitement sparked in Ye Yunfei's spirit. In one corner of the black longsword, he discovered a strange, sinister technique sealed there.
Upon closer reading, this technique was actually the core heritage secret art of the Flying Sky Yin Monkey Tribe—a terrifyingly powerful sinister yin art, said to possess the might to seal anything between heaven and earth!
In fact, this confinement art combined demonic yin laws with Spacetime Laws, resulting in a potent sealing technique.
"This confinement art is impressive, but unfortunately, I cultivate spiritual energy, while this technique requires sinister yin energy,"
Ye Yunfei shook his head.
Yet, the next moment.
"Although I don't cultivate sinister yin energy, this Netherworld Yin Blade contains a massive amount of it. I can use the energy within this blade to practice and deploy this sealing art!"
"Let's try!"
A sudden flash of inspiration struck Ye Yunfei, and he spoke his thoughts aloud.
With a millennium of cultivation experience, Ye Yunfei had studied all sorts of techniques and martial skills throughout the ages, integrating and mastering them. He was deeply familiar with the use of various energies and laws, having even created several new legacies himself!
Immediately, grasping the Netherworld Yin Blade, Ye Yunfei began attempting to harness the sinister yin energy it contained to cultivate the Nine Heavens Ten Earths Nether Confinement Art.
Gradually, eerie, sinister yin characters emerged one after another, swirling around Ye Yunfei's body, each emitting a strange sealing energy.
With their appearance, the space-time around him seemed to solidify, becoming still.
As more and more of these bizarre characters formed, the space around Ye Yunfei became densely packed with them, immersing his body within.
Time flew by.
Unknowingly, over half a year passed within the Phantom Tower.
At a certain moment...
Whoosh...
Suddenly, all the strange sinister characters surged howling back into the Netherworld Yin Blade, vanishing without a trace.
"The first level of the Confinement Art has been mastered!"
Ye Yunfei was overjoyed.
It turned out this Nine Heavens Ten Earths Nether Confinement Art was divided into seven levels.
Each level was more formidable than the last!
"I wonder how powerful the sealing might of this art is. I should find an opportunity to test it soon,"
Ye Yunfei mused inwardly.
Subsequently, Ye Yunfei left the Phantom Tower.
"The Vermilion Bird Demon King hasn't responded to my message yet."
"This Northern Frost Ancient Mining Area is far too vast."
"I don't even know which direction to search for Divine Crystals. Seems I'll have to rely on luck,"
Ye Yunfei sat within the green flying boat, directing it to fly in a chosen direction.
Around this time, news spread through the Northern Frost Ancient Mining Area.
Several monstrous creatures resembling ghost monkeys were roaming throughout the ancient mining region, killing indiscriminately. They had assaulted the mining zones of many major forces, causing widespread panic.
The strength of these monsters was terrifying. Even some ordinary elders of major powers had been killed, resulting in significant losses.
For a while, personnel from all major factions within the Northern Frost Ancient Mining Area descended into alarm, deploying strict security everywhere.
Moreover, members of those forces sent the news back to their headquarters, requesting large numbers of experts to enter the mining area to deal with those ghost monkeys.
Because if those creatures were allowed to slaughter freely, most of these factions' mines likely wouldn't be able to operate.
Not long after, many major forces reached an agreement to join forces in hunting down the ghost monkeys.
At the same time, a group of top experts roamed the ancient mining area searching for Divine Crystals.
After the news spread, the Northern Frost Ancient Mining Area became the focal point of the entire Eastern Barrens!
After the green flying boat traveled for a day.
"Hmm?"
"There's another mining zone ahead, with many mine shafts."
Ye Yunfei's gaze looked forward.
"It's actually the Zhao Family's mining zone!"
"Talk about enemies crossing paths!"
Ye Yunfei saw a few large banners fluttering in the wind within the mining zone ahead, each bearing a massive 'Zhao' character!
"Since I've come to the Zhao Family's mining zone, I shouldn't leave empty-handed."
"Let's see if there's an opportunity,"
Ye Yunfei chuckled.
Thus, Ye Yunfei immediately activated the Hidden Shadow Secret Art, carefully advancing forward.
Simultaneously, he released his Soul Power to sense the surroundings.
"There are five experts!"
Suddenly, a prickle of caution stirred in Ye Yunfei's heart.
He detected five elderly men with profound auras seated within a tent.
Ye Yunfei could sense that these five elders were formidably powerful—the five strongest beings in this mining zone.
"Hmm?"
"Everyone, I just faintly caught an elusive aura, as if something entered our mining zone."
"Could it be those ghost monkeys!"
Suddenly, one of the elders sharply opened his eyes, revealing a puzzled expression as he spoke.
"Something entered our mining zone?"
The other four elders were startled by his words.
"We must sense carefully!"
"Absolutely no mistakes can be allowed!"
"Otherwise, we five would let the family down,"
another elder said gravely.
Consequently, the five elders released their Soul Power, thoroughly scanning the entire mining zone.
Boom…
The five elders' Soul Power swept through the mining zone like five giant searchlights, faintly emitting resonant sounds.
"These five fellows seem suspicious."
"Trying to steal the Zhao Family's energy crystals might be a bit difficult now,"
Ye Yunfei couldn't help but frown.
"Kid, do you want to go steal ore crystals? I'll lead you."
"My mastery of the Hidden Shadow Secret Art is superior to yours."
At that moment, Golden-Horned Dragon Silkworm sent a voice transmission to Ye Yunfei.
After Ye Yunfei obtained the Hidden Shadow Secret Art, he had taught it to the Golden-Horned Dragon Silkworm for it to practice as well.
"Very well, let me witness your Hidden Shadow Secret Art,"
Ye Yunfei laughed.
Thus, Ye Yunfei immediately entered the Phantom Tower.
The Golden-Horned Dragon Silkworm appeared, activated the Hidden Shadow Secret Art, and instantly rushed with the Phantom Tower into the Zhao Family's mining zone.
At that time, the five elders were still scanning. However, they were utterly unable to detect the presence of the Golden-Horned Dragon Silkworm!
"See? They haven't discovered me at all."
"My race's natural talent for spatial energy isn't something to be bragged about lightly,"
the Golden-Horned Dragon Silkworm said proudly to Ye Yunfei.
"Indeed, you Golden-Horned Dragon Silkworms are innately skilled with spatial energy. It's a racial talent that's hard to refute,"
Ye Yunfei laughed.
As an ancient beast descendant, the Golden-Horned Dragon Silkworm possessed extremely high racial bloodline, and its tribe was naturally adept with spatial energy—even Ye Yunfei felt inferior in this regard.
"I found a treasury! There are so many crystals inside. Over there! Let's go!"
Soon, Golden-Horned Dragon Silkworm discovered a large cellar, piled high with many energy crystals, and immediately darted towards it.
"This treasury is heavily layered with Formations!"
"If I forced my way in, I'd definitely alert those five old guys."
As Golden-Horned Dragon Silkworm neared, it sensed the treasury surrounded by numerous high-level Formations, guarded by a contingent of Zhao Family personnel.
Though adept at spatial manipulation, allowing it to easily bypass many arrays, trying to brute force through the numerous high-level Formations around this treasury would easily trigger them, alerting the five elders.
"Dive underground. I'll study the Formations,"
Ye Yunfei instructed.
Golden-Horned Dragon Silkworm sank into the earth.
Ye Yunfei began studying the Formations.
After a short while.
Under Ye Yunfei's guidance, Golden-Horned Dragon Silkworm successfully traversed the layers of Formations and entered the treasury.
Ye Yunfei summoned Hu Miao and Huang Shang to help collect the crystals.
"We’re rich!"
Hu Miao, extremely excited, dove towards the pile of crystals.
Soon after, every single crystal within the treasury was thoroughly scavenged—not a single one remained.
"Everyone, I have a bad feeling."
"Let's go check the treasury,"
suddenly, one of the Zhao Family elders spoke.
Immediately, his figure flickered as he sped towards the treasury location.
"Alright, let's check together,"
the other four elders followed closely.
