Although Mengxi didn't guess the identity of the infant monk in front of him, he faintly felt something, and his heart was already moved with killing thoughts.

Flying down, the three-eyed demon sword in his hand bloomed with a dazzling dark red light, and a bloodthirsty aura erupted from it, and one after another black sword qi crisscrossed and turned into a vast net in the air, enveloping Xiao Tianzuo.

Xiao Tianzuo saw this kind of vast net, a strange smile appeared at the corner of his mouth, his hands pinched in front of him, and the rich evil qi in his body gushed out.

The endless evil qi rolled and contracted inward, turning into a pitch-black ball of light, and flew out of the air with a "whoosh", and in an instant, it was in front of the vast net.

Laugh at!

The vast net formed by the sword qi was broken by the black ball, and then the black ball spun in the air and flew away in one direction abruptly.

"I want to go!" Seeing the black ball flying into the distance, Mengxi almost subconsciously chased after it, how could she watch the enemy flee in front of her at this time.

Xiao Tianzuo was in the black ball, looked back behind him, and saw Mengxi, who was chasing after him, and a smug smile appeared on the corner of his mouth.

"That's it, come on, follow me" Xiao Tianzuo muttered to himself, as if everything was under his control, and at the same time, he controlled the aura emanating from his body, making him feel a little weak.

Mengxi did not doubt it, and launched a retreat pursuit in the back, in her induction, although the opponent's strength was strong, but after a fierce battle, her vitality was greatly damaged, as long as it took a while, she was sure to defeat the other party.

The two rays of light were as fast as lightning, and the direction pointed directly at the Dragon Bone Mountain.

On the Dragon Bone Mountain, Elder Xuanyin stood on a huge rock, holding a spirit plate in his left hand, and his eyes focused on the spirit plate and looked at it for a while.

"It's almost ready," said to himself, and Elder Xuanyin disappeared in place.

Under the Dragon Bone Mountain, dozens of feet deep from the ground, a huge space is filled with thick yin qi, this is a cave, but there are obvious traces of artificial excavation.

I saw that the bottom of the cave was covered with ravine-like lines, and inexplicable liquid was slowly flowing in the lines, and these liquids flowed along the lines to the central position, and finally converged into a pool in the center of the cave.

The whole space was quiet, and it felt a little weird.

Suddenly, a bright light flashed, and a huge luminous spar appeared on the cave at some point, and the soft light illuminated the entire cave.

Under the illumination of this bright light, the scene in the cave was revealed, and I saw that the red liquid flowing in those lines seemed to be a little viscous, no different from blood, and emitted bursts of pungent bloody gas.

Suddenly, a figure flashed on the edge of the pool, and Elder Xuanyin, who was originally on the Dragon Bone Mountain, arrived here at some point, standing quietly on the edge of the pool.

Suddenly, his right hand stretched out, and a huge gourd flew out, and the gourd flipped upside down in the air, and a river of blood poured down from the mouth of the gourd and fell into the pool of blood.

Whoa!

Blood-red water splashed, and circles of ripples spread around, and as the blood pool fluctuated, the bottom of the blood pool was sometimes revealed, and if outsiders were here, they would be surprised.

Under the blood of the entire blood pool, there are countless corpses, these corpses are lying in the blood pool, submerged in scarlet blood, these corpses are dressed differently, but most of them are the clothes of soul sect monks, a huge blood pool, and I don't know how many corpses are buried.

The blood in the gourd flowed for half an hour before it ran out, and it was not until there was no more blood flowing out that Elder Xuanyin put the gourd away, turned his gaze to the blood pool, and said expressionlessly: "There are so many sacrifices, it should be enough to stabilize the overall situation."

After finishing speaking, Elder Xuanyin flew up out of thin air, hovered to the center of the blood pool, closed his eyes, put his hands in front of him, formed a strange spirit seal, and recited words in his mouth.

The low voice echoed in the cavern, and with the pool of blood beneath him, it looked extremely eerie.

And as time passed, the incantations from its mouth were higher or lower, sometimes rapid, sometimes slow, with a strange aura gradually rising from the cave.

Goo-goo-goo-goo......!

And the blood pool under the body also gradually changed, I saw that in the blood pool, bubbles appeared, and after these bubbles came out, they exploded instantly, and the blood contained in them rose and dissipated in the air.

At first, the number of bubbles was small, but it didn't take long for the number of bubbles coming out of the blood pool to gradually increase, and finally the blood pool was about to boil.

Rumble!

Suddenly, the blood pool under him exploded, and a thick pillar of blood-red light rose from the blood pool, enveloping the Xuanyin Elder body above.

The blood-red pillar of light was about a few feet high, and it almost rushed to the top of the cave, and from a distance, it looked like a pillar holding up the top of the cave.

As the blood-red pillar of light appeared, Elder Xuanyin's body began to emit spiritual power fluctuations, which gradually increased as time passed.

The light of the blood-red pillar of light outside his body also became intense, and finally completely submerged Elder Xuanyin's body, and as time passed, the bright light gradually spread.

First spread from the pillar of light to the blood pool at the bottom, causing the entire blood pool to bloom with bleeding light, and then with the blood pool as the center, the surrounding lines also began to bloom with bleeding red light, and the flowing blood also began to bubble.

After about a few hours, the entire cavern was completely filled with demonic blood light, and when the last lines bloomed with bloody light, a low buzzing sound came from the cave.

Then I saw a huge blood-red formation slowly rising from the ground, suspended in the cave, the pattern of this formation was extremely complex, and the criss-crossing lines were dazzling, but the aura emitted was extremely powerful.

Just after the formation emerged, the light on the blood pillar in the center of the blood pool fluctuated, and then Elder Xuanyin flashed out and stood on the edge of the blood pool.

Glancing around, after a moment, he nodded with satisfaction, and with a wave of his big hand, a faint black light curtain rose, enveloping the entire cave, so that the slightest breath in the cave did not leak out.

After doing this, he walked to a teleportation array on the edge of the corner, and the silver light disappeared into the cave in a flash.

On the Dragon Bone Mountain, at the location of an ordinary slope, a silver light flashed in the grass, and a figure appeared out of thin air, it was Elder Xuanyin.

Seeing the location where he appeared, a teleportation array was arranged in the grass at some point, and if it wasn't for a careful inspection, it would definitely not be easy to find the existence of this array.

After coming out of the teleportation array, Elder Xuanyin raised his right hand, and a wave of energy came out of his hand and slammed into the ground beside him.

Bang!

Smoke and dust billowed out, a round pit appeared on the ground next to it, and the teleportation array was nowhere to be seen, and then Elder Xuanyin turned around and left without looking back.
