Taibai Mountains.

It is one of the famous large mountain ranges in China, with a length of more than 1,300 kilometers and a width of more than 400 kilometers, and the highest peak, Baiyun Peak, is the first peak in Northeast China.

At this moment, in the densely wooded Taibai Mountains, a figure is shuttling through the woods at a very fast speed, his whole person does not look tall, but in the run, he accurately exerts all his strength to the peak, making him shuttle through the woods at a speed that is not inferior to that of a cheetah, and in one breath, he has already crossed a distance of hundreds of meters.

"It's in this position. ”

Lu Qinghe slowed down his speed slightly, and at the same time, his eyes kept looking in all directions.

After looking at it for a moment, Lu Qinghe's expression was slightly condensed: "This place ......"

In the previous life, he was limited by his vision and knowledge, and he obtained a thousand-year-old ginseng plant here by chance, but he didn't see the unusual nature of this area, but right now, even if his divine soul strength was only a trace left, it would definitely not be weaker than those who were at the level of the true body level of the Law Phase, even if it did not reach the level of Jindan Fivefold Divine Soul Transformation, it was not far away, coupled with the extraordinary insight and realm, he could already see at a glance that the trend of tree growth in this area was different from that of other areas.

"No matter how clear the memory is, so many years have passed after all, and in the vast mountains, it will take some hands and feet to find that thousand-year-old ginseng, but now ......"

Lu Qinghe sensed it for a moment, and the light in his eyes flashed, as if he had a clear direction, and he went straight forward.

After less than three kilometers, I stopped on the side of a large rock covered with snowflakes.

Millennial wild ginseng, just ahead.

Lu Qinghe squatted down and carefully dug out this thousand-year-old ginseng, in the previous life, he swallowed it directly, and did not give full play to the effect of this ginseng, but in this life he did not intend to be reckless.

After putting away this thousand-year-old wild ginseng, Lu Qinghe did not mean to stop, and walked carefully again in the previous direction.

After walking for a kilometer, his figure stopped again and found a thousand-year-old Ganoderma lucidum next to a dead tree that had fallen for a long time.

Then he continued to move forward, spending two days in this area, walking a radius of 60 kilometers, and collecting a total of 12 medicinal herbs such as ginseng, Ganoderma lucidum, evening primrose, and rhodiola rosea, half of which were millennium-old.

"This place is not simple. ”

Two days later, Lu Qinghe stopped in front of a somewhat flat mountain in this area.

In the face of the power of nature, all traces have been covered by the changes of time, but Lu Qinghe's sensing ability is extraordinary, even if the landform here has changed greatly compared with thousands of years ago, there are still some traces of man-made traces from it.

"There is an extremely weak vitality within a radius of sixty kilometers, although these vitality qi are so weak that they can be ignored, but it is because of the existence of these vitality that the heavenly and earthly treasures in this area are far superior to other regions, and the area I am standing in now is the source of these heavenly and earthly treasures. ”

Lu Qinghe said, looking around with a glint in his eyes.

For a long time, I didn't notice anything.

But he was not depressed, he sat down directly, his mind was settled, and the power of the divine soul that had not yet recovered continued to spread around, in his sense, the mountain in front of him was no longer a mountain, the tree was no longer a tree, and the rock was no longer a rock, but a piece of heaven and earth composed of magical veins, and nine percent of these veins had become very bleak, but there was still a point that survived, extremely obscure, if it wasn't for Lu Qinghe's previous realm to reach the realm of Da Luo Jin Immortal, even if his divine soul recovered to the point of Jindan Fivefold, he still couldn't imagine sensing a fraction.

"Wait, these veins ......"

Lu Qinghe comprehended those veins for a moment in his meditation, and suddenly seemed to think of something: "These veins are actually quite similar to the structure of some small worlds...... Small world! Could it be that this is the entrance to a small world!?"

This discovery made Lu Qinghe suddenly feel agitated.

Although he had personally verified the existence of the cultivation system in the ancient mythological era, he had been in this world for decades and had never gotten any clues about the mythological era, and over time, doubts would arise in his heart, but these veins in front of him, which were similar to the entrances and exits of the small world, made the speculation in his heart completely evolve into reality.

According to the cultivation system of the ancient mythological era, if you want to completely rely on your own strength to open up a cave heaven blessed land, you need the Golden Immortal Realm, but if the Heavenly Immortal Monk obtains some heavenly and earth treasures by chance, and then uses the formation to turn the world upside down and imprison the space, he can also form a cave heaven and earth blessed land similar to the small world...... These veins in front of him are not high-level, nine times out of ten, it is a Cave Heaven World opened up by a Heavenly Immortal Monk with the help of top-level treasures supplemented by terrain and large arrays, but because no one has maintained it for a long time, the Great Array has been lost, and the vitality that was originally sealed in the Cave Heaven World has leaked a little, making a large number of top-grade medicinal materials born in this radius of sixty kilometers. ”

Lu Qinghe's eyes flashed, and he immediately carefully comprehended the remnants of this formation.

If it was a small world opened up by the Golden Immortal Monk with supreme supernatural powers, he would be helpless, but the Cave Heaven Blessed Land in front of him was obviously made up of heavenly treasures and formations, which were somewhat similar to the mountain protection array, isolating the space through a mountain protection array, thus making the inside and outside of the array completely different.

The day passed quickly.

When the sun came overhead the next day, Lu Qinghe stood up abruptly and walked straight ahead.

As he stepped out, the space in front of him seemed to ripple in circles, and the surrounding environment was also changing, being rapidly distorted.

This scene was seen by ordinary people, and they would only think that there was a mirage or a ghost, but Lu Qinghe, who knew a little about the formation, regarded it as usual, just stepping into a formation with the ability to isolate space.

As he walked forward step by step, an hour later, he finally broke through the rather mysterious formation in front of him, and then, the surrounding environment changed drastically, a green mountain and green water, surrounded by mountains, and a cloudless world jumped in front of him.

"Sure enough!"

Looking at this blessed land with a completely different landscape and environment from the Taibai Mountains, breathing in the air that was not inferior to the immortal cultivation realm of the Nanling Peninsula, Lu Qinghe's eyes flashed with surprise.

The world of ancient mythology really exists.

This Cave Heaven Blessed Land is afraid that there are tens of thousands of kilometers in length and width, and it stands to reason that such a world cannot exist on this planet at all, but for immortal cultivators, it is nothing at all to accept the heaven and the earth in a radius and turn the world into a close distance, just like Lu Qinghe's divine kingdom, in the end, it is not tens of millions of miles longitudinal and horizontal, and it is many times more vast than the world in front of him.

"So quiet. ”

Lu Qinghe looked carefully at this cave world for a moment, and immediately sensed something unusual.

Be quiet!

It's so quiet!

In this cave world, don't talk about human voices, even the roar of wild beasts is not half a sound, it is obviously a green world, but it is like a dead domain.

"This Cave World ......"

Lu Qinghe pondered for a moment, hid in a secret place, and then took out the thousand-year-old medicinal herbs he had obtained earlier and took them.

Although swallowing it directly had a certain effect on the power of the medicine, right now, in such a quiet and strange cave world, he had to do so.

There is at least one Heavenly Immortal in this Cave Heaven World, and the Heavenly Immortal, even if it is not a Heavenly Immortal like Lu Qinghe who has the help of the Qingping Holy Sword, is at least the domain level, so he can't afford not to be cautious.

Relying on the extremely accurate control of the physical body, Lu Qinghe spent six days refining all the six thousand-year-old medicinal materials, and the qi and blood all over his body were like rainbows, and the essence and blood in his body were rushing, faintly accompanied by the sound of wind and thunder, in terms of the strength of qi and blood alone, it was no longer inferior to any senior martial saint.

"I'm afraid I won't be able to catch up with the ten-day appointment with the Lord of Panlongguan. ”

Lu Qinghe felt some regret in his heart.

However, the main purpose of asking the Lord of Panlong Guan to summon those martial arts forces was to find the mystery of the disappearance of the ancient mythological world, and now, the world of a cave has been opened in front of him, and the mythological era has been confirmed, and the clues about immortal cultivators that those martial arts forces may have in their hands are not so important.

After a little self-preservation, Lu Qinghe slowly moved forward again, heading towards the place where his vitality was the strongest.

After 300 kilometers of travel, a small town finally appeared in front of him, but this town was basically no different from a ruin, Lu Qinghe judged that according to these dilapidated buildings and the surrounding terrain, this town had fallen for at least 3,000 years.

"Three thousand years ago...... According to historical records, three thousand years ago...... ...... at the end of the Yin Shang period"

If you are an ordinary person, you may be shocked by three thousand years, but it can be seen that after seeing countless old monsters that have survived for tens of thousands, hundreds of thousands of years, and millions of years, three thousand years can no longer make any waves in Lu Qinghe's heart.

Lu Qinghe continued to move forward.

The entire cave world is like a ghost domain.

But after a moment, he suddenly stopped.

He saw some huge footprints.

These footprints are definitely not left by humans, nine times out of ten, they are those powerful demon beasts, the only thing to be thankful for is that these traces are three hundred years old so far.

"There are still demon beasts in this cave world, and compared to humans, demon beasts undoubtedly have a much longer lifespan. ”

Lu Qinghe muttered to himself.

Soon, according to the fluctuation of the aura, he came to a medicine field, the medicine field was a mess, and the footprints of the demon beasts were quite dense, although they were all left three hundred years ago, but the entire medicine field was trampled in a mess.

But after all, it is an immortal medicine field, even if it is seriously trampled here, Lu Qinghe still found a large number of medicinal materials of thousands of years from this medicinal field, including some medicinal materials that are more than three thousand years old.

"I'm afraid that the truly precious medicinal materials in this medicinal field have been devoured by those demon beasts, and the rest are either ginseng, lingzhi and other things that are not strong in medicinal power, or some medicines that are less than a thousand years old...... In the hands of ordinary people, these medicinal materials can at best cultivate one or two martial saints, but they can be used by me to refine the medicinal soup, I am afraid that it is not difficult to achieve the earth immortal!"

As soon as he thought of this, Lu Qinghe couldn't wait to collect all the precious medicinal materials in the medicine field.

He is still cultivating now, and even if he is lucky enough to discover the world opened up by the Golden Immortal Cultivator in the future, he will not be able to travel through the space to enter it, so it is also necessary to improve his cultivation.

However, Lu Qinghe's collection of medicinal materials was temporarily distracted, coupled with the low level of cultivation, it seemed that some kind of alert formation had been triggered, and a somewhat dim streamer suddenly rushed into the void and spread, forming an energy fluctuation that was so weak that it could only spread for thousands of kilometers, rolling in all directions.

But such an energy fluctuation that swept thousands of kilometers suddenly woke up a hidden demon beast in the small world.

"Roar!"

With a bloody aura comparable to the Demon Emperor rising into the sky, an angry roar had already erupted, reaching straight to the sky......
