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 into the depths of the demon cave, and were cautiously and quickly sneaking in the demon cave.

Because this is not the front-line defense position of the invasion of foreign enemies in the Demon Cave, there are not even many traps and traps.

Occasionally, there were some low-level traps, all of which were detected by Su Chen's powerful divine thoughts comparable to those in the late stage of foundation building, and they were pulled out one by one, or avoided them.

The depths of the cave were silent, and not even half a figure was seen. They should all have been attracted to the front line of the Demon Cave and fought with the monks of the Immortal Sect army.

It's just that the cave is heavily damp and foul and smells unpleasant.

"It seems that our luck is not bad, go directly to the weakest point of the demon cave and kill them to the bottom. ”

Old Master Lu said happily.

With the strength of their group of monks, they were enough to sweep away the scattered enemies in the depths of the Demon Cave. At this juncture, the possibility that the Demon Demon Alliance still retains more than a dozen foundation building monks in the depths of the Demon Cave is too low.

"Yes, you might even find a lot of treasures hidden by the Demon Alliance. With such a huge force as the Demon Slayer Alliance, there must be a place like a treasury to hide treasures!"

"If there is a treasure trove, we all scratch the points, then it will be sent!"

Everyone nodded their heads, quite optimistic about the trip. Even if you don't get the reward of the Immortal Sect's military exploits, it will be a huge windfall to loot from the Demon Slayer Alliance.

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

The smell was not like the fresh blood of the usual dead, but more of a rotten and foul smell, like the smell of decay that had been rotting for decades.

What smell?

Su Chen looked around suspiciously.

Suddenly, he looked up and was horrified to find that there was a blood vessel as thick as an arm crawling on the top of the cave. It was still pulsating, as if it was like a large living blood vein suddenly growing out of the earth, looking extremely hideous, exuding a blood-colored light.

This blood-colored light made Su Chen feel very uncomfortable, but there was no obvious harm.

"What the hell is this?"

Everyone also looked up one after another, and when they saw this winding earth bloodline, they were all shocked and stunned.

Whether it is the well-informed Old Master Lu, or Ji Yuanzheng, Lu Wei and others, they are all confused. They lived for hundreds of years and were unheard of.

No one has ever seen it.

Naturally, no one knew what it was, and they didn't dare to touch it.

"It's so bad, 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, let's go!

Su Chen and the others' faces were shocked, and they no longer showed the slightest lightness, and accelerated towards the depths of the demon cave.

...

The bodies of hundreds of slain miners fell to the ground, and the blood gushed out into the low-lying pool of blood.

In the center of the blood pool, the half-zhang tall blood crystal frantically absorbed qi and blood through many cyan blood vessels, and in a short time, it absorbed the red qi and blood in the blood pool.

The ferocious blood was shining brightly, beating like a huge heart. The monstrous blood-colored fierce light was like a demon crawling out of the depths of purgatory and about to be born.

Countless cyan blood vessels connected to this "heart", and every pulse of the blood crystal sent the blood qi to the cave farther away.

The Blood Sacrifice Array hidden in the depths of the Demon Cave had already been activated, and through the bubbling blood veins of the earth, it almost enveloped the entire Tianfeng Gorge Demon Cave.

The power of the Blood Sacrifice Array was transmitted to all parts of the Demon Cave along these bloodlines.

This blood sacrifice array has only one function, and that is to use the lives of a large number of monks to trigger a strong bloody light, so that resentful spirits can be born.

This half-zhang tall blood crystal in the blood pool is the heart and control center of the entire Blood Sacrifice Great Array.

Once the large array is activated, it kills regardless of friend or foe.

The hundreds of dead miners, the remains everywhere were illuminated by the bloody and fierce light, desperately drilling out the little resentful spirits full of resentment.

They were about the size of a fist, floating like a faint cloud of blood-colored smoke, incorporeal and formless, faintly revealing the appearance of evil spirits.

Soon, there were more than 400 small resentful spirits floating in the sky above the blood pool.

"Ghost, ghost!"

"It's a vicious ghost, run for your life!"

Those five or six hundred miners in the Qi refining period who were still alive had never seen such terrible ghosts, their numb and rigid yellow faces, they were extremely frightened, screaming, and frantically scattered for their lives.

However, they were all carrying heavy shackles on their hands and feet, and they were cuffed together in groups of three or five, holding each other back, how could they escape.

"Squeak!"

These newly-born little resentful spirits suddenly discovered a large group of delicacies on the ground, and instinctively threw themselves at those mine slaves.

The little resentful spirit passed directly through their flesh and burrowed into the brains of the miners, greedily devouring the primordial spirits of the miners.

The miners screamed and fell to the ground in pieces, their faces distorted and painful.

In a short moment, this large group of small resentful spirits ate the primordial gods of the mine slaves.

From the bodies of these tragically dead miners, when they came out again, their ghost bodies had nearly doubled, and their strength had doubled.

They wandered aimlessly near the pool of blood, continuing to prey on other miners.

But there were too few minions for them to devour, and they were soon all preyed.

They have no targets to hunt for.

One of the ferocious spirits, it found that it had devoured one more mine slave's primordial spirit, which was significantly larger than the other spirits, and its strength was much stronger. Suddenly, he stared at the other little resentful spirits around him, and pounced...

Above the blood pool, hundreds of resentful spirits suddenly became chaotic, devouring each other frantically. The powerful wraith was pleasantly surprised to find that as long as it devoured other small wraiths, it could become stronger.

After another moment, the first resentful spirit, comparable to the strength of a monk in the foundation building period, was born.

It devoured more than a dozen small wraiths, which were obviously more than ten times larger than the other fist-like little wraiths, like the size of a skull, and the blood was even more ferocious.

This foundation-building resentful spirit just opened its mouth suddenly, and directly devoured a small resentful spirit nearby, frantically increasing its strength.

The other little resentful spirits all showed frightened looks, many of them were quite strong resentful spirits, but they were only in the late stage of qi refining, knowing that they were not the opponents of this foundation-building resentful spirit, they sensed the danger and frantically rushed out of the blood pool cave and fled to the cave in the distance.

...

The terrifying power of the Blood Sacrifice Array is extending to all parts of the Demon Cave through the blood veins of the earth connected by the blood pool.

Farther away from the Demon Cave, thousands of Immortal Sect monks had already entered the Demon Cave, and were fighting fiercely with thousands of monks from the Demon Demon Alliance and the Beiyi Barbarian Cultivators.

One by one, the bloody spirits in the bodies of their corpses silently burrowed out and rushed towards the surrounding monks.

Desperately absorbing the blood and death souls of the dead monks on both sides, like a tide, it grew rapidly.
