Su Chen, Wu Qiao, Ji Yuanzheng and a group of fifteen foundation-building and Qi-refining cultivators passed through more than ten miles of secret passages and entered the depths of the demon cave, and were carefully sneaking quickly in the demon cave.

Because this is not the front-line defensive position for foreign enemies invading the Demon Cave, even mechanisms and traps are rare.

Occasionally, some low-level mechanism traps were detected by Su Chen's powerful divine thoughts that were comparable to those in the later stage of foundation building, and they were removed one by one or avoided.

The depths of the demon cave were silent and silent, and even half of the figure was not seen. They should have been attracted near the front line of the demon cave and went to fight with the monks of the Immortal Sect army.

It was just that the severe dampness and filthy smell in the cave was very uncomfortable.

"It seems that our luck is pretty good. Go directly to the weakest part of the Demon Cave and kill them to the sky."

Master Lu enjoys the talk.

With the strength of their group of monks, they are enough to sweep away the scattered enemies deep in the demon cave. At this critical moment, the possibility of the Demon Evil Alliance retaining more than a dozen foundation-building monks in the depths of the demon cave is too low.

"Yes, maybe you can find many treasures hidden in the Demon Evil Alliance. A huge force like the Demon Evil Alliance must have places like warehouses to hide wealth!"

"If there is a treasure house, we will be dismissed once we scrape it!"

Everyone nodded and was quite optimistic about this trip. Even if they couldn't get the reward of the Immortal Sect and robbed them from the Demon Evil Alliance, it would be a huge fortune.

Suddenly, Su Chen, who was walking in the front, seemed to smell some strange smell of blood.

This smell is not like the fresh and blood that dies, but also has a rotten and strong smell, just like the smell that has been rotten for decades.

What smell?

Su Chen looked around in confusion.

Suddenly, he looked up and was terrified to find that a blood vessel as thick as an arm crawled on the top of the cave. It was still pulsing, as if it was a living blood vessel that suddenly grew on the ground, looking extremely ferocious, emitting a blood-colored evil light.

This blood-colored evil light made Su Chen feel very uncomfortable, but it did not have any obvious harm.

"What the hell is this?"

Everyone also looked up and saw the winding bloodline of the earth, they were shocked and shocked.

Whether it is the knowledgeable Master Lu, Ji Yuanzheng, Lu Wei and others, they all looked confused. They have lived for hundreds of years and have never heard of it.

No one has seen it before.

Of course no one knows what this thing is, and he dare not touch it rashly.

"It has a very strong evil spirit, I'm afraid it's not a good thing! I don't know what kind of monster it is. Forget it, let's not provoke it, go quickly! After looting, we will exit from the secret passage!"

Su Chen and everyone's faces changed, and there was no longer any slightest look, and they accelerated toward the depths of the demon cave.

Hundreds of killed mine slaves, their bodies fell to the ground, and blood flowed continuously into this low-lying pool of blood.

In the center of the blood pool, the half-meter-high blood crystal was crazily absorbing qi and blood through many blue blood vessels, and in a short moment it sucked the red qi and blood in the blood pool.

The extremely fierce blood light was everywhere, pulsing like a huge heart. The surging blood-colored evil light was like an evil ghost crawling out of the depths of purgatory, about to be born.

Countless blue blood vessels connect this "heart". Every beat of the blood crystal stone transports the blood evil energy to the cave farther away.

The blood sacrifice array hidden deep in the demon cave has been activated, and through the gurgling bloodlines of the earth, almost enveloping the entire Tianfeng Gorge Demon Cave.

The power of the Blood Sacrifice Array is transmitted along these bloodlines to all places in the Demon Cave.

This blood sacrifice array has only one function, that is, to use the lives of a large number of monks to trigger strong blood evil light, thereby creating a resentful spirit.

This half-meter high blood crystal in the blood pool is the heart and control center of the entire blood sacrifice array.

Once the formation is activated, no matter whether it is enemies or friends, they will be killed.

The hundreds of dead mine slaves, the remains everywhere were shining with blood and fierce light, and they desperately emerged with little resentment spirits full of resentment.

They are about the size of a fist, like a faint blood-colored smoke floating, without any body and invisible, vaguely revealing the appearance of an evil ghost.

Soon, more than 400 small resentful spirits floated over the blood pool.

"Ghost, ghost!"

"It's a fierce resentful spirit, run away quickly!"

Those five or six hundred Qi Refining Mining Slaves who were still alive had never seen such a terrible ghost. Their numb and rigid yellow faces were so scared that they were extremely frightened and screamed, scattering wildly and fleeing in all directions.

However, they were wearing heavy shackles on their hands and feet, and they were handcuffed together in groups, restraining each other, how could they escape?

"squeak!"

These newly born little vengeful spirits suddenly discovered a large group of delicious food on the ground and instinctively rushed towards the mine slaves.

The little vengeful spirit passed through their bodies and penetrated into the brain of the mine slaves, greedily swallowing the souls of the mine slaves.

The mine slaves screamed suddenly, sank on the ground and struggled in groups, their faces twisted in pain.

In a short moment, these large group of small vengeful spirits ate the souls of the mine slaves.

When they crawled out from the bodies of these tragically dead mine slaves, their ghost bodies had nearly doubled and their strength had doubled.

They floated aimlessly near the blood pool, continuing to prey on other mine slaves.

But there were too few mine slaves, not enough for them to swallow them, and they were soon hunted.

They no longer have the target of predation.

One of the fierce resentful spirits found that it had swallowed the soul of one mine slave, which was obviously larger than the other resentful spirits and was much stronger. Suddenly, he set his sights on other small resentful spirits around him and rushed over.

Over the blood pool, hundreds of resentful spirits were suddenly in chaos and devoured each other madly. The powerful resentful spirits were surprised to find that as long as they devour other small resentful spirits, they could become stronger.

After a moment, the first resentful spirit that was comparable to the strength of a monk in the Foundation Establishment Stage was born.

It swallowed more than ten small resentful spirits, which were obviously more than ten times larger than other small resentful spirits like fists, just like a head size, and the blood-colored evil spirits were even more intense.

The foundation-building resentment spirit just opened its mouth suddenly and directly swallowed a small resentment spirit nearby, madly strengthening its strength.

The other little vengeful spirits all showed terror. Among them, there were many strong vengeful spirits, but they were only in the late stage of Qi Refining. Knowing that they were not the opponent of this foundation-building vengeful spirit, they noticed the danger and rushed out of the Blood Pool Cave and fled to the distant cave.

The terrifying power of the Blood Sacrifice Array is extending to all parts of the demon cave through the blood pool.

Further away from the demon cave, thousands of immortal sect cultivators have entered the demon cave and are fighting fiercely with thousands of monks from the Demon Evil Alliance and the Northern Yi barbarian cultivators. The Immortal Sect cultivators and the Demon Evil Alliance cultivators who fell to the ground were shining with blood-colored evil light.

The blood-killing resentful spirits in their corpses silently emerged and rushed towards the monks around them.
