It's funny to say that after he caught the ghost that possessed the sea clam, another ghost hidden on the stone wall actually deceived himself and did not escape.

According to the record of "White Bone Blood Spiritual Gong", the subjugation of these three phantom spirits can be integrated into the ghost king's spiritual consciousness when the blood demon advances to the ghost king, which is of great benefit to the birth of a high level of spiritual intelligence.

Luo Yu has a deep understanding of this, and the two ghost kings who are very impressed, one of them is the silver-clothed ghost king who followed the owl crying back then, and the corpse lotus ghost king that he met later, although both of them are cultivators of the ghost king realm, but the gap in spiritual intelligence has been infinitely magnified in terms of strength.

The silver-clothed ghost king Luo Yu single-handedly killed him, but the corpse lotus ghost king made him use all his skills and couldn't kick him.

Thinking of this, Luo Yu faintly looked forward to the horror of the bloody breakthrough ghost queen.

After returning to the cave, Luo Yu took advantage of the fact that the effectiveness of the Heavenly Ghost Talisman was not lost, and took a few looks at the black pool again, and also used the method of using the Divine Thoughts and Heavenly Ghost Eyes that he had just comprehended at the same time to scan it again, but he did not find a single ghost, but there were more than a dozen low-level ghosts at the level of ghosts gathered in the black pool, and they looked like they had not even opened their spiritual intelligence.

These ordinary ghosts are useless against the blood evil, and it seems that the lonely souls and wild ghosts here are just spontaneously led to the pool by the yin qi emitted by the Xuanyin Spirit Spring, relying on the immortality of the soul.

However, although the rich Xuanyin Qi allowed the souls to be preserved, it also ruthlessly deprived them of the opportunity to reincarnate.

Although Luo Yu was skeptical of the idea that ghosts were reincarnated after death, in the face of this kind of wandering spirits that had nothing to do with it and had no power to fight back, he really couldn't be cruel enough to clean them up with a mouthful of real fire.

After pondering for a while, Luo Yu waved his hand, placed a soul-attracting ban in a corner, and at the same time took out the Hundred Soul Banner, and began to use the Hundred Soul Banner to perform the Soul Hooking Technique.

As one of the most basic spells of the Dao Sect, the soul hooking technique can also be performed by monks at the first and second levels of the Qi cultivation period, and Luo Yu naturally has his hands on it.

A moment later, a burst of yin black wind appeared above the pool, and under the rapid rotation, the black pool water was stirred up from slow to fast, and emitted a forest atmosphere, Luo Yu saw that this finger rushed to the wind pillar a little farther away, and suddenly the wind pillar shrank inward, turning into a dark pillar of light, piercing through the black pool water, and quickly probing to those wandering spirits at the bottom of the pool.

Luo Yu stood still, and his mind followed the Soul Hook Pillar to the bottom of the pool.

It didn't take long for a low roar to sound in Luo Yu's sea of knowledge, and a cloud of black gas came out, but it was sucked in by the pillar of light without the slightest resistance.

Immediately, the first ghost spirit slowly rose from under the pool water under the guidance of the black pillar of light, and its face was distorted and ugly, but it could be faintly seen that it was the face of a middle-aged man.

When the first swim broke away from the black pillar of light and flew into the soul attraction prohibition on its own, it immediately roared bitterly, as if it was asleep, and at the same time, its black mist-like ghost body gradually faded in this dream, until it completely dissipated.

Then the second and third spirits also appeared in the Soul Attraction Prohibition in turn, dissipating their soul power one by one in the same way.

After all the spirits found were returned to heaven and earth, Luo Yu withdrew the ban, breathed a sigh of relief, and took out three dark blue array flags, which were the 'Xuanyin Sealing Spirit Flag' that had just been refined, and Luo Yu was urged by the Fa in his hand, and the three blue rainbows flew out at the same time, and disappeared into the underground around the pool in a flash.

A light blue light array, just about the same size as the pool, propped up a blue bottle cap-like cover and slowly landed on the pool, seeing that this light array was running, after Luo Yu recognized it, his ten fingers began to pinch it like a wheel.

I saw dazzling golden spells, sometimes falling on the light array, sometimes quickly rushing into the black pool, in the blink of an eye, the huge Xuanyin Spirit Spring seemed to be stirred by an invisible force, and the black pool water rolled violently.

For a while, the yin qi in the cave room swelled, and the Xuanyin Spirit Spring also faintly emitted a strange black light that flashed back and forth, and if someone looked closely, they would find that there were black filament-like things in the pool slowly rising, communicating and merging with the blue light array that was staring at it.

Eventually, a wisp of dusty black light appeared in the light array, silently levitating above the formation.

It's just that this process is extremely slow, often less than one-tenth of the black mangs that can be refined from dozens of black filaments, but Luo Yu is extremely patient and tirelessly uses mana to maintain this process.

A few hours passed bit by bit, and above the light array at this time, a black and blue ball of light with a diameter of about one zhang appeared, floating in the air and shaking up and down.

And the cave room was also shrouded by a layer of diffuse black mist again because of the leakage of the power of Xuanyin, but in comparison, the yin qi contained in the black and blue light ball was many times richer than the black fog outside.

This Xuanyin Sealing Spirit Array really didn't disappoint him, and only by crossing the tribulation in such a place did Luo Yu's heart feel at ease.

When the formation was operated to the extreme by Luo Yu, and the black and blue light balls had reached saturation, under Luo Yu's move, the Hundred Soul Banners rose wildly in the wind, and below the extremely strange blood-colored thunder light on the body surface, a cold and piercing ghost roar suddenly sounded, followed by waves of blood-colored light surging and tumbling away.

In the blink of an eye, a small area in the cave was submerged by the sea of blood, and the indoor bursts of gloomy qi were tumbling and rolling, and at the same time, a blood-red face slowly emerged from the sea of blood, perhaps sensing the very rich yin qi in this place, and the blood in the eyes of the bloody black hole was flickering and intertwined, and there was a terrifying glow.

Compared with the beginning, the blood demon has changed a little, not only the two blood-colored corners on the top of the head are more obvious, but there are also two rows of raised strange bone bags on the face, and the aura is also more powerful.

It was the blood demon who sensed the existence of the ghost in the storage bag before, and excitedly reminded Luo Yu.

"Go in, I'll protect you for three days, and if nothing unusual happens, this is the place where you can cross the calamity. Luo Yu glanced at the bloody demon and instructed with a slight smile.

Whether it is blood or destiny, as he gets along with each other for many years, he seems to have invisibly regarded them as confidants and friends, and only by talking to them can he truly put his heart into his heart.

In fact, there was no need for Luo Yu to order, the blood demon took a deep sniff of the pure Xuanyin qi in the cave, the blood in the demonic eyes rose, and the black fangs in the terrifying mouth involuntarily let out a ghost cry, this kind of roar that indicated the excitement of the blood demon made people shudder when they heard it.

At the same time, after the hideous color on the bloody face flashed, the sea of blood around him rolled down, and it turned into a blood-colored rainbow and flew into the black and blue ball of light.

The light of the Xuanyin Sealing Spirit Array below trembled, and wisps of ink-like black qi emerged faster than before, continuously injecting into the two-color ball of light, and in the process of cultivating with the help of this Yin Spring, the cave quickly became gloomy and cold.

A day or two later, the blood-black light inside flashed non-stop from morning to night, filled with an eerie and terrifying aura, and every time the ghost howl from the blood demon roared, it would cause the yin qi in the Xuanyin Spirit Spring to boil and erupt once, and the black fog in the cave gradually thickened, becoming more and more yin wind gusts, like a ghost domain.

Luo Yu in the cave, who was also sitting on the side of the Xuanyin Spirit Spring, had not moved, and in front of him between his eyebrows, a black and simple jade slip was quietly suspended there.
