After rescuing Zhao Yanran, Ling Zheng found a place where no one was around, lifted the Phantom Thousand Transformation Technique, and restored his original appearance.

The Demon Cultivators of the Red Pink Palace who were ordered to hunt down other cultivators, each of them was a cultivator of the Foundation Building Realm, and any one of them was enough for Ling Zheng to drink a pot. In order to be able to leave this hidden dragon stream alive, Ling Zheng could only act cautiously and prevent them from discovering their traces.

Judging from the direction in which the group of demon cultivators dispersed before, most of them rushed to the outer area of the Hidden Dragon Stream, and there were only two or three of them going to the depths of the Hidden Dragon Stream. After Ling Zheng pondered for a while, he felt that he was still walking towards the depths of the Hidden Dragon Stream, and his hope of survival was greater.

As for the purpose of coming here to find medicinal herb seeds, he had long been thrown aside by Ling Zheng. Medicinal seeds are far less precious than their own lives.

For the sake of safety, Ling Zheng once again cast the Demon Thousand Transformation Technique, turning into the appearance of the sword-wielding demon cultivator who had fought with Zhao Yanran before, and after that, he cut off a tree trunk and transformed it into a machete with the simulacrum.

Ling Zheng recalled the demeanor and movements of the sword-wielding demon cultivator before, imitated it for a while, and after seeing that there was no difference, he took off into the air and flew towards the depths of the Hidden Dragon Stream.

But not long after flying, Ling Zheng felt that the black ancient mirror in his body was inexplicably agitated, as if he had sensed something. After Ling Zheng summoned it, the black ancient mirror immediately calmed down, which was very strange.

Ling Zheng knew very well in his heart that although he had successfully dripped blood into the black ancient mirror to recognize the master, he knew nothing about its origin, provenance, etc., except that he knew that this black ancient mirror had the ability to turn waste into treasure. Before he got the black ancient mirror from the dead Burning Flame Sect Master Wang Xu, he seemed to have heard the senior brother Lu Chen who was killed by the explosion say that this was a relic treasure.

As for which ruin, Ling Zheng didn't know at all.

Moreover, although the black ancient mirror had been restless a few times before, it had never been so strong as it was now.

"Anyway, there aren't many demon cultivators from the Pink Palace in the depths of that Hidden Dragon Stream, so it's better to go and have a look. Ling Zheng stared at the black ancient mirror and muttered.

The sky was already bright, and the clouds and mist in the Hidden Dragon Stream appeared again, looking at the white expanse in the distance, Ling Zheng once again put the black ancient mirror into his body, his body moved, and he carefully flew towards the depths of the Hidden Dragon Stream.

The demon cultivators of the Red Pink Palace hunted and killed the outer area of the Hidden Dragon Stream for a whole night, and the cultivators of the various sects who originally stayed in the Hidden Dragon Stream died directly, and the remaining four cultivators saw that the periphery had become hell, and they also fled to the depths of the Hidden Dragon Stream in a panic.

The clouds and mist in the Hidden Dragon Stream are very strange, with Ling Zheng's eyesight that is far beyond ordinary people, his vision can only penetrate the clouds and mist within a range of three zhang, which has to be said to be a strange thing.

It was almost noon when Ling Zheng came to a rock wall and was about to rest.

Before he could hit the ground, a deep purple mist suddenly pierced through the white clouds and enveloped him.

"Ahem, ahem, ahem......"

Ling Zheng choked on the dark purple mist and coughed, only to feel as if his lungs were on fire, which was very uncomfortable.

The attributeless spirit veins in his body began to vibrate wildly, and there was a faint sound of wind and flowing water, which was quite mysterious. And the pain that followed also made Ling Zheng frown, and beads of sweat appeared on his forehead.

The dark purple mist appeared suddenly, and it dispersed quickly, and after a while, it disappeared.

Ling Zheng stood in mid-air, his face first swollen red, and then he squirted out a large mouthful of black and smelly liquid. He hurriedly took out the water bladder and rinsed his mouth carefully, and then he felt better.

After the pitch-black liquid that Ling Zheng squirted out of mid-air, it was falling on a vigorous and tall old pine tree. Under Ling Zheng's gaze, the old pine tree shook for a while, then quickly withered, and when the mountain wind blew, it turned into a pile of wood residue.

"Poisonous?"

Only then did Ling Zheng come to his senses, and he was secretly glad in his heart for the attributeless spiritual veins in his body.

After being poisoned, it quickly detoxified without harming the body, which is also one of the characteristics of Ling Zheng's non-attribute spirit vein physique. It's just that when the body is detoxifying, his meridians will vibrate violently, causing him to suffer a kind of pain as if he was being crushed. Therefore, although Ling Zheng was very satisfied with this ability, he didn't want to try it often.

There is clearly something strange under the clouds. Thinking of this, Ling Zheng raised his hand and unleashed two first-order wind spell talismans, temporarily blowing away the clouds and mist below.

When the white mist lifted, there was a quiet valley with lush trees and babbling streams. On the wall at the very edge of the valley, there is a cave about half a man high, escaping a deep purple mist.

The deep purple mist that had just erupted from the cave was apparently ejected from the cave. Ling Zheng thought for a moment, floated down into the valley, and immediately summoned the Phantom Demon Bead suspended above his head, holding a second-order flame blast talisman in his left hand, and holding the Dancing Wind Sword in his right hand, he slowly approached the cave.

Because his body was invulnerable, Ling Zheng was not afraid of the dark purple mist escaping from the entrance of the cave, but he had to take a few steps before spitting out a mouthful of black water. Soon, he came to the cave more than half a man high, and saw that it was pitch black inside, and he couldn't see it at all.

Suddenly, Ling Zheng's nose moved, but in the foul-smelling dark purple mist, he smelled a strange and elegant floral fragrance.

Is there an elixir growing in this cave?

Ling Zheng stood at the entrance of the cave for a while, and finally decided to go in and have a look, anyway, he had a talisman by his side, and once he encountered danger, he could use the talisman to resist for a while, and then take the opportunity to escape.

After that, Ling Zheng bent down and walked into the cave, silently reciting the magic of the Spirit Eye Technique, making his vision clearer.

Although the entrance of this cave is a little narrow, the inside is very spacious and spacious, and a dozen people walking side by side will not feel crowded.

After only taking two steps, Ling Zheng felt a hardness under his feet, and after gently brushing away the soil, he found that it was actually a human skull.

Only the skull, the rest of the body does not know where it went.

Ling Zheng looked at the darkness in the depths of the cave, and instantly raised his vigilance to the extreme, and continued to go deeper.

This cave is very deep, Ling Zheng walked a cup of tea, saw the light in front of him, sped up his pace and walked for a while, and his eyes suddenly opened up.

The end of this cave is quite wide, with a radius of about ten zhang. There are many human bones, vestments, weapons, and so on scattered on the ground. The rocks on the ground were dark red, presumably stained red by the blood of dead humans.

But what really caught Ling Zheng's attention was the naturally formed stone platform not far ahead, which was shrouded in light at the moment. In the center of the stone platform, there is a blood-red bewitching strange flower growing quietly, and around this strange flower, there are even a little white stars twinkling.

In addition to the various grades of pills in the cultivation realm, the "Records of Pills" also records the forms, characteristics, and so on of tens of thousands of spiritual medicinal materials. Ling Zheng had already eaten the book of "Pill Chronicles" thoroughly, and after just a few careful observations, he knew the name of this bewitching and strange flower.

The Divine Blood Demon Lotus is a precious elixir that is generally only used when refining pills above the fifth grade. Legend has it that after the blood of the ancient gods dripped on the ground, it grew on its own, and its preciousness was enough to make many cultivators risk their lives to fight for it.

Ling Zheng first quietly observed the Divine Blood Demon Lotus for a while, and then looked up. The top of the cave must be connected to the outside world, otherwise it would be impossible for light to penetrate it.

But how could the unknown being, who had previously spit out a dark purple poisonous mist, not be in this cave? Could it be that he had already left the cave along the passage cast by the light?

Ling Zheng didn't rush to pick the multi-god blood demon lotus, he carefully looked around the cave a few times, and found that many bones were all jet black, or the skull was partially sandwiched in half.

He pondered the contents of the Persona book and wondered what kind of monster had done it.

But just standing there and thinking for a while, Ling Zheng heard a soft sound, which seemed to come from the channel above the Divine Blood Demon Lotus that projected light.

Moreover, with the appearance of this light sound, the light projected on the Divine Blood Demon Lotus also began to flicker and flicker.

Did I really guess it? Is that thing really hiding in that passage?

Thinking of this, Ling Zheng's body retreated sharply, and with a movement of his mind, the Phantom Demon Bead bloomed with a deep purple light, forming a curtain of light to protect him.

"Huh!"

There was a soft sound, and the cavern went dark. In the darkness, Ling Zheng saw a long shadow fall to the ground from the passage above the Divine Blood Demon Lotus.

The darkness lasted only for a moment, and then it became bright. And the shadow that fell to the ground also manifested its true face.

It was a giant centipede more than a foot long, covered with turquoise scale armor. The centipede was born with 100 legs, but at the foremost was a pair of strange feet like scorpion claws, and the two tentacles on the top of the head were like two steel thorns, flashing with a faint cold light. On its back it has two pairs of thin wings, one pair of golden and translucent, the other pair of snow-white and somewhat narrow, dotted with faint golden spots. The two pairs of wings swayed and vibrated and raised a considerable wind.

After Ling Zheng saw the true face of this demon beast, his brows furrowed, and he secretly cursed in his heart that he was really full of food and had to enter this cave.

According to the record of "Persona", this kind of demon beast is called Ghost Centipede, which is a rather difficult demon beast, not to mention its own strength, and its temperament is also extremely ferocious. In ancient times, there was a ghost centipede disaster, and thousands of ghost centipedes poured out of their nests, almost turning most of the Eastern Regions into Jedi. After that, the cultivators and demon cultivators of the five regions of the continent united and died more than 100,000 people before the ghost centipede disaster was pacified.

Since then, the ghost centipede has become a monster that everyone on the mainland shouts and fights. Ling Zheng originally thought that this kind of demon beast had already become extinct, but he didn't expect to see one in this hidden dragon stream.

Moreover, it seems that the ghost centipede in front of him has four wings, at least it is also the strength of the foundation realm, and this beast is extremely fast, coupled with the special environment at the moment, the possibility of escape is extremely low.

What to do?

Ling Zheng stared at the ghost centipede entrenched next to the Divine Blood Demon Lotus, his palms sweating, and his brows furrowed.
