Boom Rumble......

The Blood Wolf Valley let out a violent tremor.

As the figure of the wolf disappeared, the ten-zhang high blood wolf head pattern on the cliff slowly changed, as if it had life, the huge wolf's mouth slowly opened, and the wolf's teeth were staggered, forming a huge hole in the smooth mirror-like cliff. Two pillars of blood-colored light that originally shone into the wolf's eyes shone into the cave through the opening.

Boom! Boom......

With the appearance of the cave on the cliff, eighteen dark stone pillars slowly sank into the ground, and the stone pillar top station and the ground of the square were tightly seamed, and it was extremely smooth.

An extremely terrifying coercion, with the aura of passing through the ancient times, rushed from the black cave. Eighteen black giant wolves bore the brunt of this coercion, their black hairs standing upside down like steel needles, and their eyes were full of fear. Although the blood wolf behind was far away, because of its weak strength, the blood wolf that was close to it was oppressed by this power and knelt on the ground. Iron Wolf also felt a little unwell. However, his body could not move, and could only bear it.

It took about half a pillar of incense for this coercion to gradually dissipate.

"Come in!"

From the cavern came the calm voice of the wolf.

When all the wolves heard this, they all rushed to the entrance of the cave as fast as they could, and one after another wolf shadows flew up and jumped into the cave......

The iron wolf hurriedly sensed it with his divine sense.

In front of you is a large-scale stone hall carved out of the interior of the mountain, surrounded by dark stone walls. The stone walls are carved with ancient murals, mainly wolves, but also other beasts and humans, and many places have been mottled and difficult to distinguish due to the passage of time.

The wolves' expressions were obviously awe-inspiring and solemn, and they walked gently on the floor of the stone hall.

There was not a single pillar in the stone hall, and some unknown gems of dark red color were inlaid on the four walls, reflecting the entire hall in a strange blood red. On the inner side of the main hall stands a two-zhang tall statue, which is still a giant wolf with an incomparably powerful, domineering, and even brutal atmosphere.

The wolves quietly walked around the statue, revealing a passage behind it.

After entering the passage, the light began to dim, but a faint blood-colored light still filled the entire space.

Iron Wolf's mood at the moment was also quite apprehensive, and he vaguely felt that there was something very special in front of him that attracted him, making him extremely eager to rush there. Although his body lying on the black wolf's back was still unable to move, there were blood-colored rays of light rushing out of his chest from his body.

Soon, the wolves arrived at a grotto that was not too large. The iron wolf's divine sense swept away, and the scenery inside was unobstructed.

This is a square round grotto with a radius of more than ten zhang, the center of the stone hall is a square blood-colored altar with a length and width of about four zhang each, about two zhang high, each of the eight directions is locked with a black iron chain of arm thickness, and the other end is fixed in the mouth of the blood-colored stone wolf statue set up in the eight directions of the grotto. The stone wolf statue is kneeling, and its demeanor is extremely respectful. The altar, the black iron chain, and the blood-colored stone wolf statue were faintly painted with all kinds of strange ancient runes, and it seemed that blood was dripping, and the evil qi was surging, and the wolf shadow was heavy.

The snow-white but shimmering red wolf knelt reverently in front of the altar, whining and roaring incessantly, and suddenly opened his mouth, spit out a crystal bead, emitting a blood-colored light, and wrapped around the altar......

The wolves soon gathered behind the wolf, kneeling to the ground. The iron wolf was placed directly in a corner of the grotto by Jin.

The white wolf's figure slowly stood up, standing firmly facing the altar, and roared twice in his mouth.

When the eight strongest blood wolves heard the order, their bodies were as fast as the wind, and they rushed to the front of the statue of the eight blood-colored stone wolves on the ground, and each blood wolf raised a front paw almost at the same time and slammed it on his chest.

Poof! poof......

Mouthfuls of blood suddenly splattered on the blood-colored stone wolf statue.

The eight-headed blood-colored stone wolf statue flickered with blood, and strange and ancient runes flashed on its surface, like electric currents, rushing along the black iron chain from the altar in the middle of the eight directions.

Boom!

The entire altar was completely lit up, and blood-colored brilliance rushed in all directions, making the entire grotto completely shrouded in blood light.

Burst!

The last wolf condensed a mouthful of essence blood and sprayed it on the bead that had been spit out of his mouth earlier, and the bead was immediately full of blood, like a small sun, illuminating the entire grotto.

Thundered......

Finally, the blood-colored altar let out a loud bang and slowly sank downward......

Iron Wolf's Divine Sense swept and found that there was a semicircular blood-colored light shield at the top of the altar, and his divine sense could not find out what was inside the light shield. However, judging from the coercion faintly released from it, it was obviously much stronger than that of the Sky Wolf. At the same time, the iron wolf also felt that wisps of summoning were coming from this blood-colored light mask.

"What could it be in there? It was even more terrifying than the Sky Wolf, could it be a mysterious beast?"

Suddenly, just as the top of the altar was level with the ground, the iron wolf's body trembled violently, and an imperceptible blood-colored streamer on his chest shot out quickly, shooting into the light mask with lightning speed.

The Iron Wolf felt his soul twitch for a while, as if something had been pulled out of his soul, and he almost fell unconscious. But he could clearly see what was inside the mask!

Boom Rumble......

The altar was still slowly rising, and the original altar had become a black stone pool four feet square. The wolf stood quietly on the edge of the pool, his eyes fixed on the mysterious shield of light, and there was also a hint of doubt in his eyes. Obviously, it doesn't know exactly what's inside the mask.

Click......

When the altar sank to the ground about four zhang deep, with a few crisp clicks, the wolf kisses of the eight blood wolf statues slowly opened, and streams of bright red blood were quickly poured into the square pool, and with the continuous infusion of blood, a real blood pool was formed.

The wolves kneeling on the edge of the blood pool were excited, and they got up one after another to patrol around the blood pool, their eyes revealing the cold glow of excitement, and their breathing began to become rapid.

The iron wolf naturally saw all this with his divine sense.

Click!

There was a crisp sound in his ears, and the wolf mouth of the eight-headed blood wolf stone sculpture automatically closed, no longer spurting blood outward.

In the pool of blood, the blue blood rippled, and huge bubbles kept churning upward, as if boiling, exuding an extremely strong bloody breath outward.

"Whew!"

The Sky Wolf stared at the pool of blood with an indifferent look, and then let out a short, short roar.

Eighteen blood-colored wolves suddenly rose up and pounced straight into the pool of blood......

As the wolves entered the pool, the boiling blood suddenly appeared a thumb-sized, crystal clear, shining mini blood wolf, frantically pounced on the wolves, and fiercely burrowed into the bodies of these blood wolves. Although these miniature wolves are small, their energy is extremely terrifying. After being drilled into the body by the mini wolf, all the blood wolves trembled all over their bodies without exception, the bloody wolf hair on their bodies stood up like steel needles, and their eyes were filled with fear and perseverance, bearing extreme pain.

Only then did the iron wolf know that this wolf sacrifice should actually be regarded as a kind of refinement. Of course, the Iron Wolf who had used the Flame Crystal to refine his body knew how painful the process of refining his physical body was, but once he persevered, the huge benefits were self-evident.

Boom!

A bloody wolf kept struggling and fluttering, but its body finally couldn't bear the huge energy, and it exploded with a bang, turning into a puddle of blood and disappearing, and it didn't even have time to whimper. Immediately after that, the second and third heads ......

In a few moments, fifteen powerful blood-colored giant wolves burst into pieces one after another under the blood infusion, and their bodies were shattered and died, leaving not even a skeleton behind. Only the three blood wolves persevered to the end, and were thrown up by a huge force, their blood-colored hair had turned purple and black, and their bodies were larger than their previous feet, and their unprecedentedly powerful aura kept releasing from their bodies, which was almost the same as the eighteen black giant wolves.

Eighteen black wolves came to the three purple-black giant wolves who had succeeded at the same time, whining and growling, as if to congratulate them.

Of course, the iron wolf didn't know that at this moment, these three purple-black giant wolves had completed the transformation from fierce beasts to spirit beasts, which was a qualitative leap!

The wolves are well aware of the dangers and pain in the pool of blood. However, the wolves were unmoved, and the second batch of eighteen bloody wolves rushed down the pool of blood again, and this time five blood wolves were successful.

Until the end, twenty-nine of the one hundred and eight blood wolves successfully survived the training of the blood pool and became powerful purple-black giant wolves. The other seventy-nine powerful blood wolves were completely turned into blood in the pool of blood.

In the pool of boiling blood, there seems to be a unique smell of their bodies.

The wolves lined up and walked around the pool of blood three times, constantly whimpering and whispering into the pool of blood, which was the lament of the deceased......

The color of the pool of blood became darker and darker, from red to purple, and finally to purple-black. Clouds of purple-black gas gushed out incessantly. With a cold breath. The purple-black gas gradually converged into five crazy black wolf shadows above the blood pool, each of which actually carried lightning bolts on its body, exuding a violent aura.

Woohoo!

In the midst of the surging blood pool, five black shiny things suddenly flew out of the blood pool, quickly gathering the black wolf shadows above the blood pool, condensing into five fierce light wolves about a foot long and as black as ink, running quickly and irregularly above the blood pool.

"Yes! This time, five Yuan Spirits flew out together, two more than the last time. Five of you will be able to obtain them and break through to become high-level spirit beasts!The rules are the same as before, whoever grabs them will be whom, go for it......"

"Roar!"

Seeing the formation of the little black light wolf, the eighteen black giant wolves could not hold it back, and under the command of the heavenly wolf, they let out a low roar, volleyed up in the air like a meteor, opened their bloody mouths, and chased after the little light wolf that was flying fast......
