，！

He walked into the cave again, his ears twitching again, and he heard the sound of the wind whistling from the other side of the cave.

"Huhu ......" The sound of the wind was like a fierce beast roaring, which made Qin Feng's heart stir.

He took a few more steps forward, and found that there were two more doors in the innermost part of the cave, and a strange feeling rose in his heart again, as if there was a huge whirlpool in it, which was constantly attracting him.

"Strange, what is calling me? I shouldn't be wrong. Qin Feng said to himself: "Could it be that there are any treasures here, or some magical treasures?" “

Thinking of this, he couldn't help but look forward to see if there were any treasures and magical things in it, but after looking at it for a long time, he found that there was still nothing in it, only these two doors, and nothing else was found.

"Could it be that my feelings are wrong?" Qin Feng frowned, he was a little confused in his heart, feeling that he might have encountered something strange.

"No matter, try it first!"

He secretly decided in his heart that since the door was closed, he had to go in and see what was the magic that could produce such an effect and make him so strongly attracted.

He walked inside the door, and he was shocked by what he saw behind the door, for he found that behind the door he had entered was an empty room.

There are many bronze pillars carved with various ancient characters in the room, and there are many strange patterns on them, some of them are humanoid, some are of a fierce beast, some are of demon beasts, and some of them are devils.

The patterns are somewhat peculiar and somewhat quirky.

However, Qin Feng found that although these strange patterns were strange, they did not bring him any danger.

Because in the middle of these strange patterns, there is a faint white mist, which looks unreal, as if it will be blown away at any time.

Seeing such a picture, he was a little curious, walked forward, stretched out his hand and gently touched the white mist, and suddenly, he felt a warm energy transmitted from the white mist.

He found that this energy not only did not pose a threat to him, but made him feel comfortable.

"What is this energy? How can it be so magical? He was amazed and incredulous.

He continued to walk forward, and the closer he got to the white mist, the stronger his feeling became, and the more he felt that this white mist was not simple.

He stepped forward again, and when he was only about a meter away from the white mist, he noticed that the light in the white mist had become stronger, stinging his eyes.

Qin Feng hurriedly blocked his eyes with his hand, unwilling to let this light blind his eyes.

After his eyes regained vision, he carefully observed the white mist, and found that the light of this white mist was obviously many times stronger than just now, and it contained a strong aura, which made him feel a sense of depression.

This aura was very strong, more powerful than the might of some martial saints, and he felt that if he was not careful, he might be directly swallowed by this white mist.

"It's so powerful, what the hell is in here? It has such a powerful aura! Qin Feng sighed, a little surprised in his heart, he had never seen this kind of breath.

"This kind of breath feels a little familiar to me, as if I've seen it somewhere, but I can't remember where I saw it for a while."

Qin Feng muttered to himself, thinking quickly in his mind, wanting to think about this question, but he wanted to break his head, and he still couldn't figure out where he had seen this kind of breath.

"Forget it, I'd better take a look at the situation in this room first!" He sighed, no longer thinking about it.

He continued to walk forward, and he found that the closer his body got here, the stronger and more terrifying the aura became.

"That's amazing! It's terrifying. Qin Feng was shocked.

His body involuntarily accelerated, and he found that the closer he got to here, the more intense the strange aura became, and the white mist became clearer.

When he finally came to this room, his heart twitched, and a look of shock appeared on his face, this room was exactly the same as the valley outside.

He stood in this room, and there was a palpitating feeling that made him shiver, and he felt like a tiger that had fallen into its prey, and that prey was like a lion, ready to pounce at any moment.

Qin Feng didn't dare to hesitate, he hurriedly looked around, trying to find the exit in this room.

All around him, the walls of this room were covered with strange runes, and his eyes shone with a wonderful light, and he kept looking around for an exit.

Suddenly, he saw the strange rune on the wall, but it was so strange that he couldn't read it.

"Hey, how can there be such runes?" He was surprised, and looked at the rune carefully, trying to learn something from it.

He looked closely, and soon saw that the rune was not an ordinary rune, but a landmark in the city, and he recognized the building as the place where his parents had lived, and he remembered it well.

But he was very puzzled, this is obviously a valley, how can there be such a city?

He thought for a moment, and felt that this matter must have a lot to do with the white mist in the valley, maybe that white mist really had something to do with his parents.

"Could it be that the souls of my parents are sealed in this?" Qin Feng guessed that this idea was ridiculous, but he felt that it was very likely that this white mist was indeed not something that ordinary people could use, and he had never heard of any sect that could seal the soul of a dead sect disciple.

Other than that, he couldn't think of any other reason to explain it.

Qin Feng stared at the runes on the wall, carefully examining these runes, and he found that each rune emitted a soft white light, like white jade, crystal clear, very beautiful, very beautiful.

He found that each rune seemed to be wrapped in some kind of energy, and this energy was very pure, very pure.

He carefully examined the runes on the wall, and found that these runes were different from ordinary runes, each rune was different in color, but the breath of each rune was different, and the aura contained in it was very strange.

The energy in this is very special, like a mysterious energy.

However, he didn't know how to figure out the energy in it, so he studied it carefully for a long time, and finally shook his head and decided to give up.

His current strength is too weak to understand the mystery at all, and he will not be able to figure out what is in it when his strength is strong enough.

At this time, he suddenly saw several porcelain vases placed next to him, with a lot of handwriting on them, but those handwriting was very unfamiliar.

He was curious, and leaned over to take a closer look, and he saw that there were a few drops of elixir in it, and there were also two notes, which recorded the medicinal effects of these elixirs, as well as the process of refining them, and the materials needed, etc.

He picked up the porcelain vase and found that there were several charms on it, each spell was different, as if it were some kind of spell, and he tried to read it, and sure enough, the runes all responded, constantly rotating in the air, forming various shapes.

These shapes look like a dragon, like a phoenix, like a unicorn, and like a phoenix, all kinds of forms, all kinds of abilities, he is dazzled.

However, the energy in these spells is terrifying, each of them seems to have the power to destroy everything, and each ability is different, it cannot be synchronized, but used separately, which is an eye-opener for Qin Feng.

No matter how much he tried, those energies didn't listen, and they couldn't be used synchronously.

"What a wonderful rune! It looks very mysterious, but it can't be used synchronously, which is very uncomfortable. He was a little helpless, feeling that the magic of this spell was far beyond his imagination.

But he thought about it carefully, and felt that this spell could not be considered magical.

Although he didn't understand how these charms worked, he did understand that the power in these charms was very strong, and it was not something that ordinary monks could bear, and if they were used incorrectly, the consequences would be unimaginable.

"It seems that you still have to study this rune first, and only after studying the runes in it thoroughly can you use these runes at the same time, otherwise you will use these runes rashly, and I am afraid that the consequences will be unimaginable." Qin Feng thought about it and made a decision.

He decided not to use these runes for the time being, he was going to study them slowly, and one day he would master these charms and be able to use them as he pleased.

Thinking of this, he put those bottles into the storage ring, he felt that it was more important to study the runes first, as for the matter of these elixirs, I would talk about it later.

He walked over to the bed, carefully observing the runes on the walls.

The runes on the walls are all ancient, some are broken, some are complete, and some are even lost.

"What kind of rune is this? Is it really where my parents once lived? But why does the city exist? And none of the people in the city have ever seen these runes. "He thought the city was too weird.

He looked at the runes on the walls again, and he saw that some of them were mutilated, but some were intact, as if the spell had existed in the first place.

He wanted to write down all the runes on the walls, but there was a forbidden memory in the city, and he couldn't get the information unless someone specifically recorded all the runes in the city.

He unwillingly opened a porcelain bottle, the bottle contained a kind of elixir, he tried to taste the elixir with the tip of his tongue, the taste was very strange, a little bitter, but with a hint of sweetness, very special taste.

However, he quickly understood, because the taste in those pills was a special energy, just like some herbs, which could increase the true yuan in a cultivator's body.

He tried to swallow a pill, and suddenly a warm energy entered the abdominal cavity, and then ran in the meridians, these energies followed the meridians, directly into the dantian, the dantian, there was a wisp of flame burning in his dantian, his dantian was filled with a scorching energy, like magma burning, a scorching air flow in the meridians.

"That's amazing! Being able to make a flame burn in the dantian was like a kind of energy, and this energy could nourish the body and greatly increase my cultivation speed. "He's amazing, it's amazing, he's never been in a situation like this before.

"Is this elixir called Nirvana Pill?" He thought of a book from the classics.

It is recorded in the classical books that in ancient times, there were countless strange treasures between heaven and earth, and many people fought desperately for a strange treasure every year.

At that time, the strange treasures between heaven and earth were very rare, each of them had its own unique energy attributes, and it could double the cultivation speed of cultivators, but it was also extremely dangerous, and there was a danger of falling if you were not careful.

Moreover, these strange treasures are guarded by those who have cultivated strongly, and if anyone dares to touch these strange treasures, then they will definitely be hunted down.

Therefore, during that period, those people were desperately trying to snatch those strange treasures, and they were desperate to compete for them.

Sometimes the fighting will last for months or even years, even decades, sometimes even hundreds of years, and I don't know how many people have been killed or wounded.

The tragic battles of those years can be said to have terrified countless cultivators, and I don't know how many people died in that battle.

However, after these strange treasures were unearthed, many cultivators went crazy and flocked to those strange treasures one after another.

There are many cultivators who do not hesitate to sacrifice their lives to obtain the strange treasure, just to be able to obtain the huge energy contained in that strange treasure, which makes the strength of many cultivators greatly improved, and some people even rely on this method to further cultivate and reach the Yuanying realm.

With this kind of exercise, many people started to follow suit, and even many people started to use this method to improve their strength, which made those people even more crazy.

However, the strength of those people is very limited, and it is difficult to obtain the huge energy contained in the strange treasure.

Therefore, at that time, some powerful people were reluctant to leave here, and wanted to wait for the opportunity.

After Qin Feng discovered this secret here, he immediately took action and began to explore in this city.

He shuttled through the city, searching incessantly.

The cities of this era are very prosperous, the streets are full of people, traffic, shops, restaurants and inns, all kinds of shops are open, and a rich atmosphere of life.

And the city is very big, there are many cities.

Some cities are very far away, but they can communicate, no matter where cultivators can use soul power to communicate, whether it is a cultivator or ordinary people, they can use soul power to communicate.

And in this city, you can also feel a faint spiritual sense fluctuation, as long as you are willing to use your divine sense to investigate, you can find that there are some people in this city who use their divine sense to detect the movement around them, and they are the guards of this city.
