Cultivation begins in the endless sea.

It turned out that when Lin Qing first fought the sea monsters in this area, he found that these monsters were quite similar to the Black Pool he had encountered by chance in Qinglong Bay Market.

Upon seeing the two demons in the passageway, he became even more certain that the two must have a connection.

"Indeed, they are still a loving family."

Limited by the "Mysterious Origin Beast Suppression Manual", Lin Qing can only control first-order demonic beasts and cannot control the second-order Black Tan Primordial Spirit from before.

However, he didn't pay much attention to it, treating it as a way to pass the time during his cultivation in the Beast Taming Ring. He never expected it to come in handy here.

Speaking of which, I actually got quite a few good things from the storage shells in Black Pool back then.

One of the handwritten notes in the "Black Clan's Ancestral Canon of Ten Thousand Scales" records that there is a saying about an ancestral lineage among the seven major clans of the demon race.

The lifelong dream of an ordinary demon vein is to soak in the ancestral vein pool, connect with the ancestral vein's spiritual energy, and awaken their innate supernatural abilities.

This place is one of the Black Clan's demon lairs. It does not have the Ancestral Vein Pool, but it does have a Yin Vein of Earthly Fiends, which slowly changes the physique of the Black Clan members through day and night tempering.

"Since the great change in the spiritual energy of heaven and earth, the ancient method of refining evil into essence has been lost."

"However, if the Chongxuan True Water is re-tempered in the Yin Vein of Earthly Fiends, its power will definitely increase many times over."

"After all, compared to the underground cold veins, the Earthly Fiend Yin Veins are undoubtedly of a higher grade."

With this in mind, he urged his black-light primordial spirit to leave the battle area and avoid other demonic beasts, while simultaneously "squeezing" the "residual value" of the primordial spirit.

"Tell me, where exactly is the core of your demon lair's forbidden formation located?"

Upon hearing this question, the black light's primordial spirit trembled violently, as if it had been greatly stimulated.

Lin Qing frowned; it seemed that the message had been blocked by the divine sense of a high-level cultivator.

"What about the Earthly Fiend Yin Veins?"

The black light's primordial spirit gradually calmed down, and after a short while, it slowly transmitted its voice: "This humble servant will lead the way for you, sir, please..."

"Once it's done, I'll send you into reincarnation..."

Compared to being reduced to ashes, the reincarnation of the primordial spirit is already the best ending.

Upon hearing Lin Qing's promise, the black light primordial spirit gradually stabilized, and with a flash of eerie light, it disappeared into the complex passageway with Lin Qing.

……

The blue bell at Li Xiaoshuang's waist swayed silently a few times, and the low-level sea monsters in front of her scattered in disarray.

Her crescent-shaped eyes revealed a rare hint of seriousness. With a flick of her slender hand, a second-tier talisman floated out of her talisman pouch, transforming into a shimmering blue orb that enveloped her. She then became a streak of light, brushing against the wall and disappearing in a flash.

A moment later, she appeared in a small cave with a slightly flushed face.

"call-"

Even with the superior talisman bestowed by her family, the spiritual energy consumed by the rapid stealth, coupled with the intense concentration required to sense the aura pulling her, was making things somewhat difficult for Li Xiaoshuang.

"Fortunately, we finally found this place."

With a flick of her wrist, a small jade bottle floated in front of her.

Behind the veil, her beautiful eyes gleamed with a strange light, and her fingers moved swiftly, forming hand seals. In no time, the two sealing talismans on the jade bottle were removed, and a drop of blood essence, crimson in color with faint black ripples, floated out of the bottle.

This is a secret treasure of the clan, a drop of Black Clan blood essence seized during the sea beast tide years ago. The clan uses this drop of blood essence as a guide to make drawing talismans twice as effective with half the effort.

"This time they actually came to the lair of the Black Clan."

"We have to make some plans for the family, no matter what."

Li Xiaoshuang pondered to herself. The Li family's talisman-making tradition has a long history, and if traced back further, it can be traced back to an ancient sect on the mainland.

However, due to the limitation of spiritual materials, their own talisman-making skills have been stuck at the second level and have not progressed.

"If I could enter the Black Clan's Blood Pool and condense more essence blood, perhaps I would still have a chance to break through to the third-tier talisman."

Li Xiaoshuang gritted her teeth and continued to channel her essence blood into the cave entrance in front of her.

"disease!"

Essence and blood are connected to the earth's energy; bloodlines bind people of the same clan.

As magical power was continuously injected, the drop of essence blood flowed slowly along a mysterious trajectory on the cave wall, eventually forming a faint totem-like mark.

"Buzz—"

With a gentle ripple, the cave gate opened automatically.

A look of joy flashed across Li Xiaoshuang's face. She then channeled her magic power into the second-tier protective talisman before carefully slipping inside.

"Buzz—"

As she entered, the door closed automatically.

The cave was surprisingly dry.

Li Xiaoshuang subconsciously looked around. The cave was about forty or fifty feet square, with smooth stone walls all around. Not far away, a curtain of water descended from the sky and slowly flowed out from the underground ditch.

Behind the waterfall, on the flat ground, stands a stone platform as tall as a person.

In the center of the stone platform was a blood pool, about two feet square. From afar, one could see the blood and evil energy surging within the pool, its brilliance flashing incessantly.

"Is this the Black Clan's Blood Pool?"

Sensing the immense malevolent energy within the blood pool, Li Xiaoshuang hesitated. Then, she took out a small, jade-green brush, held it in her hand, and slowly moved forward.

When they were half a step away from the water curtain, something unexpected happened!

The water curtain moved without wind, suddenly swelled several times its original size, and in an instant, water splashed everywhere, like a silver waterfall cascading down.

With a "whoosh," it struck Li Xiaoshuang's protective aura, causing it to tremble violently.

In a moment of desperation, Li Xiaoshuang rapidly spun the magical artifact in her hand, just as it was about to form a stream of light, the waterfall curtain crashed down again, tearing through the spiritual light in an instant!

Li Xiaoshuang's face turned pale. She only had time to take half a step back to avoid being drenched, but she couldn't avoid being soaked all over.

"Buzz—"

"It's so cold—"

He sensed strange changes in his body, and his spiritual power was constantly suppressed. Since the Qi refining process began, he experienced the unusual phenomenon of feeling cold.

How could Li Xiaoshuang not be alarmed!

Without hesitation, she retreated to the entrance, raising a handful of talismans to protect herself. A small, emerald-green brush hovered above her head, creating a pale green barrier.

She quickly swallowed several pills, disregarding everything else, and began to fully circulate her cultivation technique to resist the strange spiritual power.

……

Under the guidance of the Black Light Primordial Spirit, Lin Qing evaded most of the guards, while the small number were swiftly and decisively killed by him.

After witnessing Lin Qing's various methods, the Black Light Primordial Spirit became increasingly cautious, fearing that it might accidentally annihilate its soul.

After a short while, they stopped in front of a dark cave entrance.

Lin Qing's expression shifted between light and dark. She finally confirmed, "Are you sure it's outside this cave entrance?"

The black-haired primordial spirit swayed its "figure" and said obsequiously, "Master, I once guarded this place. This cave entrance leads to the location of the Earthly Fiend Yin Vein."

"But what about deeper inside, the smaller ones wouldn't know..."

"snort…"

"I'll trust you this once!"

With a wisp of gray light, Lin Qing used the Five Elements Water Escape technique to disappear into the dark, deep trench at the bottom of the sea, silently and stealthily moving away.

The Foundation Establishment cultivator's divine sense enveloped his entire body, cautiously probing the surrounding environment.

Cold, dark...

This does feel a bit like the Earthly Fiends.

only…

After sneaking for several dozen meters, Lin Qing suddenly felt a chilling aura, like a silver ribbon from the heavens, crashing down upon him.

"not good!"

"Gagaga... I'm Black Sea..."
