In the cave, you can't see your fingers, and the dark and damp environment can't help but make people feel a little frightened.

A few slight footsteps, wandering back and forth in the cave.

"Big brother, it's so dark here, Frost is a little scared." Shuang'er, who was held up by Lin Beichen, said timidly.

Although the fear on her face could not be seen at this time due to the light, it could be felt in her trembling voice.

"Don't be afraid, big brother will do a magic trick for you." Lin Beichen's gentle voice floated back and forth in the cave.

In the next second, a slightly flickering yellow flame flashed out from Lin Beichen's palm, and then jumped in front of several people, slowly dispelling the darkness of the cave.

"Wow, big brother, you can actually set fire, it's amazing!" Frost clapped her fleshy little hand and screamed in surprise.

Those little eyes sparkled and were full of envy.

"Hahaha, when you get to the hometown of the eldest brother, the eldest brother will teach you." Lin Beichen smiled heartily, and couldn't help but be a little amused by this little girl.

Hearty laughter wandered back and forth in the cave, and listening to the sound return time, it seemed that the end of the cave was about to be reached.

Sure enough, the group walked for a few more minutes and finally reached the deepest part of the cave.

The space here is extremely vast, but it is even more damp and dark, and the wisp of fire from Lin Beichen before is no longer enough to completely illuminate the space here.

At that moment, Lin Beichen randomly took out a few low-grade spirit crystals from the system, threw them on the wall as before, and then controlled the wisps of yellow flames to ignite the spirit crystals in turn.

Suddenly, the entire cave was illuminated with blue light, and the vision was clear again.

And after doing this, Lin Beichen gently put down the frost he was holding, then turned to look at Long Aotian and the Yin Jue Old Man, and after a little silence, he said: "This time is equivalent to retreat and cultivation, as for how long it will take to break through, I am not sure, you should take care of the diet of Cangxuanzi's predecessors and Shuang'er during this time." ”

As he spoke, a wry smile couldn't help but appear at the corner of Lin Beichen's mouth.

So far, he has shown no signs of wanting to break through. Of course, he also understood that it had not been long since he had only broken through to the fifth layer of the Heavenly Yin Realm, and it would be too difficult for him to break through again in a short period of time.

With this eye closed, I don't know when I will be able to open my eyes.

Thinking of this, Lin Beichen continued: "During this time, the two of you should discuss with each other and take turns on duty, and the other person can also use this time to cultivate or rest." ”

After hearing this, several people nodded lightly and accepted Lin Beichen's arrangement.

Then, Lin Beichen's eyes glanced at the faint light coming from the entrance of the cave, and fell into deep thought.

After a long time, he suddenly came back to his senses, looked up at Long Aotian, and said, "Brother Long, can I exchange five thousand spirit crystals with you?" ”

After that, in his palm, fifty medium-grade spirit crystals emitting purple light flashed out.

"Naturally, you can." Long Aotian smiled and counted the number of spirit crystals from the Qiankun bag in his arms, then threw a handful to Lin Beichen, his eyes flickered, and after a slight groan, he said: "No need to change it, Brother Lin, you can take it directly, I, Long Aotian, am not bad for this spirit crystal." ”

After that, he smiled and pushed back the fifty medium-grade spirit crystals handed over by Lin Beichen.

"Oh?"

Lin Beichen was slightly stunned, and then glanced at Long Aotian deeply.

Listening to this meaning, Long Aotian seems to be a big money.

He didn't think about it until now, as if he had never asked Long Aotian's identity and background.

Seeing the doubts in Lin Beichen's eyes, Long Aotian showed a proud look on his face and explained: "I am not a person who cannot be brought in, nor am I from Dark Sun City, but from the royal family of the Great Sage Dynasty. ”

As soon as these words came out, Lin Beichen's expression was even more puzzled, and he was just about to ask, but he heard the shocked voice of the old man.

"The Great Sage Dynasty you are talking about, is it the high-level dynasty located in the eastern part of the Southern Regions?" The old man's thin and sallow face was shocked, and his eyes were full of surprise when he looked at Long Aotian.

Long Aotian glanced sideways slightly, raised his eyebrows slightly, and at the same time, the corners of his mouth were unconsciously hooked up a touch of arc, and said with a smile: "In addition to this Great Sage Dynasty, is there any other dynasty that dares to call itself the Great Sage Dynasty?" ”

"Shhh It's true, no wonder the old man saw that you had reached the fifth layer of the Heavenly Yin Realm at such a young age, and it turned out that you were a member of the royal family of the Great Sage Dynasty. ”

The Yin Absolute Old Man sighed, revealing a look of surprise.

"The Great Sage Dynasty? High dynasty? ”

At this moment, Lin Beichen became more and more confused the more he listened.

"In the entire Southern Regions, there are four high-level dynasties, which are located in the eastern, southern, western, and northern regions of the Southern Regions, and this Great Sage Dynasty is a high-level dynasty located in the eastern part of the Southern Regions."

"The Southern Region is vast, there are countless dynasty sects, like the old man of the Xuanling Dynasty to which you belong has never heard of it, and it is likely to belong to a low-level dynasty."

"And the strength of these high-level dynasties is no less than the top sects that the old man told you before."

"If the royal family of a dynasty has a Xuandan realm, it can be called a low-level dynasty. If you have one high-level monk in the Xuandan Realm and several in the Xuandan Realm, you can be promoted to an intermediate dynasty. ”

"If there is a realm powerhouse in the dynasty, then this dynasty belongs to a high-level dynasty, and the Great Sage Dynasty to which Long Aotian belongs is among them."

A hint of envy appeared on the old man's face, and he said like a treasure.

With this background, if the talent is still good, even if you can't break through to the realm realm in the future, the Xuandan realm is a certainty.

Some people were born in Rome, and some people were born cows and horses.

Sure enough, people are more angry than people.

"Low-key... low-key..."

Listening to the introduction of this yin old man, although Long Aotian said this, the corners of his mouth rose more and more.

Anyone can see that he is humble and polite.

He was extremely satisfied with his own origin, and countless people would show envy after hearing that he had reported to his home.

This greatly satisfied the vanity of his twenties.

In fact, he took the initiative to tell his family background and also had his own little abacus.

If Lin Beichen was really the kind of person who didn't keep his word, he would be able to use this to deter Lin Beichen's greedy heart.

This is also a means of self-preservation for him, after all, he has only known Lin Beichen for a short day or two, and he can only observe Lin Beichen's character from the surface and draw simple conclusions, but what Lin Beichen thinks in his heart is unknown.

Anyone who wants to take all the meat away from his Long Aotian mouth will have to weigh his own ability.

The wrath of a high-ranking royal family is not something that anyone can bear.

That's going to be a million corpses!

"I see."

Lin Beichen bowed slightly, and then glanced at Long Aotian. With just one glance, he saw through his careful thoughts, and then he could only smile helplessly.

Long Aotian's actions were redundant, he never thought of monopolizing it in his heart, he was not such a person, and he couldn't do this kind of thing.

He still understands the truth of drinking water and thinking about the source.

"Then you're welcome."

Lin Beichen raised his eyebrows slightly, and then took the medium-grade spirit crystal in his hand back into the storage space of the system.

"Brother Lin can use it casually, but I still have it. My parents once said that money is something outside the body, as long as you have strength, you can get as much money as you want. Long Aotian patted his chest heavily, and his tone was extremely arrogant.

"Your parents are right, I agree." Lin Beichen grinned.

My neighbor is my granary, and my neighbor is my granary. In the face of absolute strength, anyone must surrender.

This is an eternal truth.

At this time, Long Aotian asked the doubts in his heart and said, "By the way, Brother Lin, what do you want this spirit crystal for?" I think you seem to be quite full of aura. ”

As far as he knew, it seemed that spirit crystals only had three uses.

One is to restore the aura consumed in the dantian, but this path is relatively slow compared to the elixir. When it comes to an emergency, such as in battle, pills are usually used to recover. Methods such as using spirit crystals to restore aura are also only used in normal aura restoration.

The second is the use of arranging the magic circle, and the spirit crystals needed to arrange the magic circle usually require a large number of spirit crystals, and most of the spirit crystals consumed on the continent are also used for this purpose.

The third is for trading.

Aside from these three uses, Spirit Crystals are of little use.

But it is clear that two of these three uses are not applicable in the current scenario.

"Could it be... Brother Lin, do you want to set up the magic circle? ”

Long Aotian seemed to have thought of something, and couldn't help but grow his mouth and asked with a shocked expression.

Lin Beichen smiled slightly, and asked rhetorically, "Otherwise?" ”

"Cow! That's awesome! I admire Long Aotian! Long Aotian's face was full of disbelief. He didn't expect Lin Beichen to have this level of identity.

As a member of the royal family of the Great Sage Dynasty, he naturally knew what the way of the magic circle represented.

This is a profession more precious than that of an alchemist.

At the same time, a powerful magic circle master, even if he has no cultivation on his body, as long as he arranges a magic circle with extremely strong attack power, he can still kill thousands of troops.

But the magic circle masters are not like alchemists, they never show the layout method of every magic circle they know.

As a result, in the entire territory of the Southern Regions, the magic array masters were far rarer than the alchemists.

"Low-key... Low-key..."The corners of Lin Beichen's mouth hooked a trace of arc, imitating Long Aotian's demeanor and language.

In this regard, Lin Beichen was really helpless, he didn't want to show the magic circle in front of people, he had to hide this cave.

Since they can find this cave, maybe the young man in Huafu can also find it. Once he hasn't broken through, he will be discovered by the young man in fancy clothes first, and then it will be difficult to escape.

And just now, he had already thought of a foolproof strategy, directly sealing the entrance of the cave with a magic circle and hiding this cave, so that even if the young man in Chinese clothes was standing near here, he would not find that there was a cave here, let alone know that there were still them in the cave.

And the magic circle he was going to arrange was the 'Concealment Array' that he had used several times, a low-grade magic circle.

Helplessly, the spirit crystals left in his body were less than five thousand at all, so he could only reach out and exchange them with Long Aotian. And these five thousand low-grade spirit crystals are used for this purpose.

The familiar circle was arranged again, his technique was extremely skillful, and after just an hour, the mysterious aura enveloped the entire cave.

And the cave gradually became illusory, until it disappeared completely. If someone were passing by outside at this moment, they wouldn't have noticed that there was a cave hidden in front of them.

And after doing this, Lin Beichen showed a smile of satisfaction.

Everything is ready, and now you can cultivate here with peace of mind until you break through to the sixth layer of the Heavenly Yin Realm.

"I'll wait for you......"
