It is rumored that 30,000 years ago, the creatures of the Demon Domain broke through the boundary barrier for some reason and descended on the land of Xiling, and the Heavenly Demon Tribulation broke out, and the two demon clans were inevitably involved. Under the demon calamity, the human race suffered heavy damage, and the nine immortal gates went to save five, and the demon clan suffered heavy casualties and suffered great damage to their vitality......

After the Demon Tribulation, the entire Xiling land was full of holes and disorder. After the creatures of the Demon Domain left countless small Demon Domains, they gradually retreated.

Whether it is the small demon domain at the bottom of the peak of the Jinyun Peak of Qinglingmen, or the small demon domain in the depths of the burial demon ancient forest, or the more than 30 small demon domains in the territory opened by the prince Zhou Yin with the help of the power of the dynasty, they are all left by those demon domain creatures 30,000 years ago, although these small demon domains were quickly sealed, but a large amount of demonic qi has poured out, and the entire Houzhou land seems to be covered with a thin layer of mist, gray and gloomy. Staying in such an environment for a long time will make the whole person bloodthirsty and cruel, and even lose his mind.

However, the land of Houzhou is so vast, and the population of the people is billions, after all, only a few can be transferred, and the rest can only be left to fend for themselves.

Blood Wasteland, Zhentian City, once the first level of the next week. The walls of more than 50 zhang and covered with blood-stained moss towered into the sky and stretched endlessly. In the hearts of the people of the Later Zhou Dynasty, this Zhentian City, which has gone through thousands of years, is like a towering mountain, as if it will never collapse.

However, faith in the heart is not enough to change the difference in strength. After Zhentian City was completely breached by Great Qin's Black Armor Xuan Army, it had been reduced to a dead city. The mottled city wall has long since collapsed and decayed, littered with stones, and under the sunset, you can only remember and reminisce in your heart.

In Zhentian City, the decaying dry bones will occasionally attract some hordes of birds and beasts, and under the accumulation of gray clouds in the sky, it seems that they have come to the Netherworld Ghost Domain, not to mention ordinary people, even if they are cultivators, they are also hairy in their hearts.

When Kong Laosan came here, it was already three months later.

Standing on the edge of Zhentian City, recalling the tragic scene of killing the heavens and flying flesh and blood, Kong Laosan sighed lightly, shook his body, and directly drove the light towards the depths of Zhentian City.

Three years later, not much seems to have changed. However, the deeper he walked, the more Kong Laosan had a gratuitous irritability that came out of his heart, and this feeling came inexplicably. Sensing this, Kong Laosan immediately stopped, looked around, and frowned slightly. After thinking about it, the power of divine thoughts surged out from the center of his eyebrows, and he probed around.

After a full cup of tea, a trace of clarity flashed in Kong Laosan's eyes, after three years of brewing, the dead qi and blood qi scattered from the bones of this place were mixed with those demonic qi remaining between heaven and earth, and gradually merged and converged in the depths of this town and heavenly city, gradually forming a strange filthy qi.

This kind of filth has the power of demonic energy to disturb the mind, and also has the violent and killing meaning of death and blood, and perhaps after tens of thousands of years of evolution and fusion, some strange creatures may be born here. (After the spirit realm, returning, forming, foreshadowing)

As soon as his mind moved, the spiritual power in his body suddenly condensed into a green armor, completely isolating these filthy qi, and his body stretched out, and he walked towards the depths again.

However, just when there was still a long distance from the original bone refining place, Kong Laosan suddenly stopped his body, and all the power of his divine thoughts was mobilized, and he probed towards the "Bone Refining Array" not far away.

It is said that it is the "Bone Refining Great Array", but in essence, it is the same as the "Spirit Gathering Great Array", except that the "Bone Refining Great Array" has been slightly changed, and it has formed a special connection with the underground corpse bones, which is no different. One gathers the filthy qi, and the other gathers the spiritual power of heaven and earth.

After thoroughly exploring the "Bone Refining Great Array" in the distance, and even sweeping the surrounding grass and tree environment, Kong Laosan's thoughts returned, and a trace of joy flashed on his face. The divine sense swept over, and did not find any abnormality, and even the several illusion prohibitions that were casually arranged before leaving were intact, and it was not until this moment that Kong Laosan completely put his mind at ease.

It wasn't until he stepped into the formation and observed it up close that Kong Laosan frowned slightly, thought about it, flipped his palm, and a thin booklet fell into his hand, and the three words of "Yin Spirit Sutra" were particularly conspicuous.

The white bone puppet, one of the five types of alien weapons recorded in the Yin Spirit Sutra, once refined, only needs to devour the backbone of living beings, and the more it is swallowed, the stronger the power of the white bone puppet will be.

After studying the booklet in his hand again, Kong Laosan closed his eyes for a long time, and after a while, he opened his eyes, and with a slight movement between his fingers, a drop of blood shot out from between his fingers.

After two hours, Kong Laosan pursed his lips, and there was two points of hesitation in his eyes. At present, this "white bone puppet" is still a little short of heat after all, and it has not been refined in three years, and I don't know if it is due to the wrong way of refining it, or the abnormal environment here.

According to Kong Laosan's estimate, if this "white bone puppet" wants to be completely formed, it will have to wait at least another five or six months. After thinking about it, Kong Laosan still decided to wait here, for a cultivator, five or six months is not a long time.

With a flip of his wrist, three storage bags, one black, one green, and one yellow, fell in front of him. Kong Laosan was not polite, he held the black storage bag in his hand, and with a wave of his hand, he erased the imprint of the divine thought at the seal, and with a slight shake, a bunch of miscellaneous things fell in front of him, in addition to dozens of spirit stones, some bottles and jars of pills, and the identity tokens of the disciples of the outer sect of the Qingling Sect, there are also some refining materials, etc., in addition to these, there is also a copper square box the size of a palm.

Glancing at the things in front of him, Kong Laosan waved his hand, and put the spirit stones and pills into his storage bag, his eyes skimmed over the rest of the things, and finally fixed on the square box in front of him.

The copper box in front of him is quite heavy, and there are some quaint gold inscriptions printed on it, and there is a faint glitter of spirit at the opening, which is obviously forbidden by something.

Sensing this, Kong Laosan's heart moved, and the power of divine thoughts broke out of his body, and he carefully probed towards the copper box in his hand. After a full stick of incense, his eyes narrowed, and he casually pointed out a spiritual pattern, and after waving several prohibitions towards the wooden box, with a "crunch" click, the copper box in his hand opened in response, and a blood-colored jade slip and a palm-sized golden order lay quietly in it.

Jin Xiaoling is nothing special, the unique identity token of the Jin family, just glanced at it, and didn't care. What interests Kong Laosan the most is the last blood-colored jade slip.

The jade finger in front of him was long and short, flat and blood-red, and there was a faint flow of viscous liquid in it. There was a hint of curiosity in Kong Laosan's eyes, and he put the jade slip on his eyebrows and briefly probed.

After half a cup of tea, Kong Laosan's face showed a touch of surprise, what was recorded in the jade slip was a secret technique unique to the Jin family, called "Blood Escape Technique", just hearing this name, Kong Laosan unconsciously thought of the scene when the golden shadow turned into hundreds of blood shadows and fled in all directions, but this blood escape technique seems to have some flaws, and it is difficult for Kong Laosan to be sure if he has time to carefully explore it in the future.

Putting the jade slip aside, Kong Laosan's eyes swept towards the other two storage bags, his eyes were slightly hot, and he was not polite, and directly shook the two storage bags together, and suddenly, a large number of things fell in front of him.

In Kong Laosan's eyes, ordinary things were naturally ignored, and he pulled among these things for a long time, and finally left only two flying swords, a cyan jade slip, a small pile of spirit stones, and some bottles and jars of elixir, as for some other low-level refining materials, magic robes, and goods, they were swept away by Kong Laosan like garbage.

Looking at the cyan jade slip in his hand, Kong Laosan's eyes revealed a touch of heat, as if he was expecting something, put the jade slip on his eyebrows, and carefully probed it.

This time it took two hours, and when I opened my eyes, there was no surprise on my face with a hint of joy, but there were faint doubts mixed with two points.

What is recorded in the jade slip is a secret technique called "Soul Gathering Technique", through careful investigation, Kong Laosan found that this so-called "Soul Gathering Technique" was the secret technique that Huang Chenggui forcibly improved the power of the soul with the sixth layer of qi refining in the Qingling Gate, but from Kong Laosan's eyes, this secret technique does not seem to be specially used to enhance the soul of the soul, but seems to be a means of condensing the remnant soul.

Looking at the two jade slips, one red and one green, Kong Laosan hesitated for a moment, then put the red jade slip into the storage bag, rubbed the cyan jade slip in his hand twice, and closed his eyes again to investigate......
