After Xia Ruofei put away all the 12 boundary stones, the white beaver couldn't wait to gather all the small pile of boundary stones that belonged to it, and then chewed it heavily.

Just like the feeling of the beaver when he saw Xia Ruofei put away the boundary stone, Xia Ruofei was also distressed when he saw the beaver eating the precious boundary stone into his stomach like this.

However, since both parties have agreed, Xia Ruofei will not go to the mouth of the beaver to snatch it again.

The beaver crunched and ate the boundary stone like chewing ice, and Xia Ruofei began to look at the small cave.

As soon as Xia Ruofei entered the cave, all his attention was attracted by the pile of boundary stones on the stone platform, and now he looked around carefully, and found that in addition to the most conspicuous stone platform, there was also a sculpture in the innermost position of this cave.

The sculpture is about three meters high, and it is a middle-aged man with beautiful hair, this middle-aged man is wearing red armor, holding a halberd in his hand, and his body exudes a majestic momentum.

In particular, the eyes have a breathtaking feeling from every angle, as if they are not a sculpture, but a real person.

In front of this sculpture, two boxes, one large and one small, are placed side by side.

Xia Ruofei tried to use his spiritual power to investigate, but found that as soon as the spiritual power reached the surface of this box, it would be immediately repelled, and it seemed that this box seemed to have the effect of shielding spiritual power.

Xia Ruofei suddenly became interested.

He carefully used his spiritual power to probe all around the sculpture, but he didn't find any formations, not even the most basic formations.

So, Xia Ruofei walked to the sculpture and squatted down in front of the slightly larger box.

The chest was made of wood, but it was impossible to tell what kind of wood it was, and the dark brown chest had a shiny surface that looked very sturdy, giving it the impression of ironwood.

The box was not locked, Xia Ruofei cautiously reached out and grabbed the handle, and then gently lifted it up.

Without any incident, the box was opened directly.

What caught Xia Ruofei's eyes was a piece of crystal-like things neatly stacked, each of which had a standard diamond-shaped structure, looking crystal clear.

Xia Ruofei was slightly disappointed at first, because there were no new boundary stones here as he expected.

But after thinking about it, if there was a boundary stone here, it would not be possible for the world beaver to be indifferent by now, and even when he walked over, the world beaver didn't even lift his eyelids, and still gulped down his "food".

Then Xia Ruofei became a little interested in these diamond-shaped "crystals".

Can be stored in a chest, and there is such a complex formation outside to protect it, these "crystals" should not be ordinary.

Just when Xia Ruofei was about to ask Xia Qing, Xia Qing in the Lingtu space couldn't help but exclaim: "Lingjing! It's actually Lingjing!"

Xia Qing was obviously just a spirit puppet, but Xia Ruofei seemed to be able to feel the strong surprise in his words.

"Spirit Crystal?" Xia Ruofei asked puzzled, "Xia Qing, what is a Spirit Crystal?" Is it a Spirit Stone?"

Xia Qing said: "Master, how can the spirit stone be compared to the spirit crystal? Let's put it this way! The spirit stone is just a stone that contains a certain amount of spiritual energy, which is helpful for the cultivation of monks, although it is relatively rare, but the spirit stone with a slightly lower spiritual energy content can still be found. ”

"What about the spirit crystal?" Xia Ruofei asked.

"Spirit Crystal...... It can be said that it is a spirit stone with a spiritual energy content of ten percent!" Xia Qing said, "In fact, the spiritual crystal is formed by the extreme concentration of spiritual energy, and now the concentration of spiritual energy in the spiritual map realm has reached the level of atomization, and if the concentration continues to increase on this basis, a liquefied spiritual energy will be formed......"

"So, the spirit crystal is a product of the extremely high concentration of spiritual energy, which causes the spiritual energy to solidify?" Xia Ruofei's voice couldn't help but tremble a little.

"Yes!" Xia Qing said excitedly, "After the spiritual energy is solidified, it must be this form that forms this diamond, and each spiritual crystal contains a massive amount of spiritual energy. To take the simplest example, all the spiritual energy in our spirit map realm can be extracted and compressed, and at most one or two spirit crystals can be formed!"

Xia Ruofei couldn't help but be dumbfounded, he was very clear about the concentration of aura in the spirit map space, and every once in a while he would go to the space to cultivate, the reason was that compared to the barren environment outside, the concentration of aura in the space was too great.

He once dreamed that one day, he would be able to cultivate in such an environment all the time, and that cultivation would definitely be a thousand miles in a day.

I didn't expect that such a rich aura could only form one or two spirit crystals when all of them were gathered.

And in this box in front of me, there is a box full of spirit crystals!

At a glance, you can see that there are at least hundreds of spirit crystals in it!

This is simply an incomparably large amount of wealth, even compared to the 12 boundary stones that have just been obtained.

"Xia Qing, are these spirit crystals good for the Spirit Diagram Realm?" Xia Ruofei asked in a trembling voice.

Xia Qing said: "Master, the Spirit Map Realm cannot directly absorb foreign aura, but they are of great benefit to the master's cultivation, now the cultivation environment is extremely poor, even if the master cultivates in the time of the child and the time of the mao, the effect is not obvious, if you hold a piece of spirit crystal when you are cultivating, and directly extract the spiritual energy contained in it to cultivate, the effect is naturally not the same." And in this way, you don't have to wait for the time every day, with the spirit crystal in hand, you can cultivate at any time!"

"I see. Xia Ruofei's breath became a little chaotic, and he was very excited.

He subconsciously turned his head to look at the white raccoon.

The little guy was crunching and eating happily, perhaps sensing Xia Ruofei's gaze, it also turned its head to look this way, and its gaze even swept over the box of spirit crystals, but it showed a disdainful look, not interested in them at all.

Xia Ruofei also breathed a long sigh of relief and said, "It seems that this trip is really the right one, this time the harvest is too great!"

After speaking, Xia Ruofei was ready to collect all these spirit crystals into the spirit map space.

At this time, Xia Qing reminded: "Master, I suggest that you better collect this box together." If I'm not mistaken, this box should be made of thousand-year-old black root wood, which can block spiritual power, and it can be regarded as a good treasure. Moreover, the spirit crystal is kept in a thousand-year-old black wood box, which can also avoid the loss of spiritual energy. ”

"Understood!" Xia Ruofei said.

Then he closed the lid of the box, and directly put the entire box into the Lingtu space with a direct thought.

His divine mind sensed that this box had appeared in the primordial realm of the Spirit Map Space out of thin air, so he completely relieved his mind, and these precious spirit crystals also belonged to him in the true sense, and there were no branches.

Xia Ruofei then cast his eager gaze on another slightly smaller box.

This slightly smaller box is also made of thousand-year-old black wood. The big box just now had already given Xia Ruofei such a big surprise, so what treasures would there be in this small box?

Xia Ruofei's heart was full of anticipation.

He reached out and opened the box, which was also unlocked, and couldn't wait to look up.

"What is this?" Xia Ruofei couldn't help but muttered to himself.

In this small box, there are 8 small flags lying quietly, each with a different pattern painted on it.

These patterns are a bit like formation patterns, and seemingly chaotic lines form mysterious lines.

Xia Ruofei said with some uncertainty: "Could it be that this is the formation flag?"

He had just learned the knowledge of the formation path, and when he cracked the stone wall formation at the door, the level of the formation path had also improved by leaps and bounds, so he thought of the formation flag for the first time.

The array flag is also a tool for arranging formations, which is specially refined by the masters of the formation path for arranging special formations, but this method is relatively old, and it has gradually been lost in later generations, so the formation classics that Xia Ruofei came into contact with are only mentioned, but there is no detailed introduction.

So Xia Ruofei was just guessing in his heart.

The array road classics in the earth word jade talisman are not in detail, and Xia Qing naturally doesn't know what these small flags are, so everything can only be explored by Xia Ruofei himself.

He picked up one of the small flags and looked at it, there should be no doubt that there should be a formation pattern on it, but this formation pattern is different from all the basic formations that Xia Ruofei has learned, and it seems to be a completely different system, so Xia Ruofei can't start if he wants to study it.

The material of the small flag is not silk or cloth, and it is slightly rough to the touch, but it is very tough, and it must not be ordinary.

Xia Ruofei picked up another small flag, and at this moment, his eyes were slightly fixed, he reached out and put down the two small flags, and then groped in the box.

Next, there was an extra jade talisman in his hand.

It turned out that this jade talisman was placed at the bottom of the box, covered by the 8 small flags, and Xia Ruofei didn't notice it at first.

When he picked up the second small flag just now, the corner of the jade talisman was revealed, and Xia Ruofei saw it.

For such a jade talisman, Xia Ruofei is no stranger.

It is essentially no different from the herringbone jade talisman and the ground character jade talisman, both of which are used to store information, which is equivalent to the "mobile hard disk" of the cultivation realm.

The difference is that there are no lines on this jade talisman, Xia Ruofei tried to penetrate the spiritual power into the jade talisman, and immediately read the information inside.

Thinking that this jade talisman is the "standard version", and the herringbone jade talisman and the ground character jade talisman that he came into contact with before are probably "customized versions", the purpose is to prevent people who are not strong enough in spiritual power from encountering danger when accepting the inheritance, and those lines are equivalent to a threshold.

Xia Ruofei read the information in the jade talisman, and the joy on his face became stronger and stronger.

Through the introduction of the jade talisman, Xia Ruofei knew that these 8 small flags were a set of array flags, and relying on them could arrange a very magical formation.

The only effect of this formation is to change the flow rate of time.

This kind of formation that can change the flow of time is extremely profound in Xia Ruofei's opinion, in fact, the Lingtu Space Yuan Primal Realm is a closed space with the time formation arranged, and with Xia Ruofei's current formation level, he can't even understand the basic formation pattern of this formation, let alone successfully arrange it.

But with these 8 array flags, Xia Ruofei only needed to arrange the array flags according to the directions introduced in the jade talisman, and he would naturally be able to arrange the time formation.

This set of formations can reach up to 100 times the time flow rate.

Xia Ruofei even thought that if these 8 array flags were used in the territory of the early Yuan Dynasty, he didn't know if the effects could be superimposed.

If you could, it would be terrifying.

The Yuan Chu Realm originally had thirty times the time flow rate, and if a hundred times the time formation was superimposed, the time flow rate would reach a terrifying three thousand times, which means that after one day in the outside world, the time in the formation would be nearly ten years!

Of course, this is only the limit of what 8 array flags can achieve.

In fact, the effect of using this set of array flags to arrange the time formation is inversely proportional to the range of the formation.

The time formation arranged by these 8 array flags can cover a maximum radius of 2 miles, of course, in this case, the time flow rate can only reach ten times the time flow rate in the formation.

And if the range of the formation is as small as only about three feet in radius, it can basically reach 100 times the time flow rate of the limit.

This is also very, very big for Xia Ruofei.

First of all, if he cultivates any elixir that takes a lot of time to grow, with this time formation, it is simply a super ripening agent!

In addition, this time formation can also be used in the outside world, which is even more significant.

What's even more amazing is that if these 8 array flags change their orientation and formation technique slightly, they can also instantly turn into time deceleration formations with diametrically opposite effects.

It can be said that if used properly, the role that this set of array flags can play is simply too great.

"Baby!" Xia Ruofei's eyes lit up, and he unceremoniously put the array flag and jade talisman into the wooden box.

Then with a wave of his hand, he also put the wooden box into the spirit map space.

It also takes a certain amount of practice to use the formation flag to arrange the formation, but the current Xia Ruofei obviously doesn't have time to get familiar with it, so it's better to put it away first, and after leaving this underground palace, it's not too late to study it slowly.

Xia Ruofei didn't expect that in addition to the boundary stones, the harvest this time was so big.

He set his eyes on the statue with the halberd in his hand, and he even had the slightest idea of taking it with him.

However, Xia Ruofei also subconsciously felt that this statue was very dangerous, especially those eyes seemed to be able to see through people's hearts, if he stared at these eyes, he even had a feeling that his soul would be sucked away.

Take 10,000 steps back and say, the two boxes Xia Ruofei got today should be enough to be related to this sculpture, and with such a big benefit, Xia Ruofei naturally will not be disrespectful to this sculpture.

He respectfully bowed three times in front of the statue and said, "Thank you for the generous gifts of your seniors! The juniors must cherish these cultivation resources and strive to pursue a higher realm!"

After finishing speaking, Xia Ruofei looked at the white beaver again.

The rest of the boundary stones have been eaten up by it, Xia Ruofei really can't imagine that this realm beaver looks like a kitten, how can it hold so many things in its belly?

After all the boundary stones were eaten, the stomach of the boundary fox was only slightly bulging, and it didn't look like it had been eaten at all.

Moreover, after eating so many boundary stones, the white beaver has no signs of evolving at all, just sighing there.

Xia Ruofei walked up to the white raccoon and asked, "Little guy, now that I've helped you get what you want, can you also help find my friend?" Do you know where she went?"
