"Strange, is there something wrong?" Lin Xi asked when he heard this.

"The spiritual power of this elixir is not weak, but there don't seem to be demon beasts next to it!" This is not an important matter, Chen Yan did not hide it, and said it directly.

"Is there such a thing? Let's go over and take a look!" When Lin Xi heard this, he also felt a little strange.

This distance was not far, and the two of them reached the place where the black bone grass was in a few breaths.

Chen Yan coupled with his pseudo-divine sense, the farthest detection distance was only about five hundred meters, which was already beyond the level of a Qi Refining Stage cultivator.

During the Qi refining period, if there is no special ** case for cultivation, a normal cultivator, cultivating to the tenth level of Qi refining, the farthest distance that the divine sense can reach is only about 400 meters.

After all, everyone's own quality is different, and it is impossible to have the same results.

So, this black bone grass is not far from them.

However, as Lin Xi approached, she also discovered the location of the elixir, and as Chen Yan said before, she didn't sense the existence of demon beasts around her.

This swamp is not all mud puddles, and in some places the soil is hard, and this black bone grass grows on such a piece of land.

Chen Yan looked around, and this piece of land is not small, the width is about forty meters, and the length is about seventy or eighty meters.

It's not easy to have such a field in this swamp.

Such a protruding piece of land, covered with tiny bushes and rotting dead wood.

Under these few pieces of decaying wood, there was a black spirit grass about half a foot high.

It is a three-leaf shape, and each leaf is made up of several rib-like bones, but it is not clear what kind of animal it is, but it bears some resemblance to the ribs of a human monk.

"Hey, it turned out to be black bone grass, not bad", when he came closer, Lin Xi nodded and said to himself.

However, his expression was full of surprise, and then there was a hint of solemnity.

It didn't take long to find a fourth-order elixir in the swamp, and this luck was not bad.

And it seems that this elixir is very important to her.

However, her expression did not relax, and she carefully observed her surroundings.

With the medicinal power of the fourth-order elixir, she naturally wouldn't think that there was no demon beast to protect her.

However, in her divine sense, there was indeed no breath of demon beasts, and she could not sense the existence of demon beasts around her.

"What's the matter?, does this elixir fairy need?" Looking at Lin Xi's expression, Chen Yan thought for a while and asked.

Lin Xi asked him to help find the elixir before, but she didn't say what it was, but now looking at her appearance, it seems that this black bone grass is one of them.

"Hehe, Brother Chen guessed right, this black bone grass is indeed very important to the little woman, and I hope Brother Chen will be successful."

"But this black bone grass is also a fourth-order elixir, it is very valuable, if you can find the foundation building elixir and divide it from my share and give it to Brother Chen, what do you think?"

"Since the fairy needs it, you can take it! If you give it to me, it won't be exchanged for a spirit stone elixir when you go out, but Fairy Lin, what's the use of you taking this black bone grass? This elixir can't be taken out, and when you go out of the spirit realm, it's not changed to a spirit stone or an elixir"! Lin Xi's words made Chen Yan a little puzzled, this black bone grass was a little bit of a treasure as far as he knew, although it was also a cherished elixir.

But it's just a pill for refining the middle and late stages of foundation building, and it can't be exchanged for a foundation building pill.

Now Lin Xi is actually willing to give up a foundation building elixir in exchange for Chen Yan, although the foundation building elixir that Lin Xi said cannot be realized now, but if she can really find the foundation building elixir in the future, is she really willing to exchange it!

Moreover, Chen Yan didn't look like Lin Xi was lying, besides, she didn't lack such a fourth-order elixir, so she was willing to exchange it for the foundation building elixir.

"Hehe, wait a minute, Brother Chen will know, now let's pick this black bone grass first, so as not to have too many dreams at night", Lin Xi finished speaking, and walked to the side of the black bone grass, this black bone grass is not guarded by demon beasts, she is also a little strange, but there is nothing to worry about, even if there are demon beasts, at most it is only a first-order superlative.

But as long as there is no such demon beast whose strength is close to the foundation building period, it is fine.

Then Lin Xi took out a jade shovel and carefully shoveled it towards the black bone grass.

Seeing this, Chen Yan was a little puzzled, as far as he knew, this black bone grass could be picked and stored directly, as long as he paid attention to it, he didn't need to let the venom in the leaf stem flow out, because this venom was also the most important.

When refining the elixir, in addition to the leaves of the black bone grass, you also need the juice inside.

But it's not so careful, right, digging with a jade shovel? This black bone grass doesn't seem to have these particulars!

But Chen Yan was puzzled, and he still observed Lin Xi's actions and didn't ask more.

If Lin Xi wants to talk about this, he will naturally say it, but if he doesn't say it, he will ask in vain.

Lin Xi brought the jade shovel close to the root of the black bone grass, and with a slight stroke, he immediately pulled out a wound, and a black liquid suddenly flowed out of it, and this liquid slowly flowed out of the wound and into the soil below.

Before, Chen Yan thought that Lin Xi was going to catch this venom, but who knew that it would be so expensive.

Slowly, the venom in the leaves and stems of the black bone grass slowly flowed out, while the black black bone grass slowly changed color and slowly took on a hint of green.

The black liquid was flowing extremely slowly, and after about a quarter of an hour, the black liquid was no longer flowing from the wound under the black bone grass.

At this time, the black bone grass is no longer all black, but now it has become black with green, a kind of black and green.

Seeing this, Lin Xi's face was overjoyed, he put away the jade shovel, and then took out a white vial from the storage bag.

Pull out the plug, close to the root of the black bone grass wound, and slowly pour out a drop of ru white liquid, dripping on the wound of the black bone grass.

As soon as the white liquid touched the black bone grass, it slammed into the wound as if it were alive.

Immediately afterward, in a state visible to the naked eye, he scurried around in the black bone grass.

Lin Xi did everything without avoiding the statement, but he didn't explain anything.

Seeing this, Chen Yan was even more puzzled, at this moment, Chen Yan suddenly frowned, turned his head to the left, and then said to Lin Xi: "Fairy Lin, stop first, there is a demon beast coming."

When Lin Xi heard this, he looked up at Chen Yan, and was just about to ask, when he suddenly turned his head to look to the left, the speed of this demon beast was very fast, and Lin Xi had obviously discovered it.

However, the fog around was very large, and although it had been found in the divine sense that there were demon beasts coming towards this side, there was still a gray patch in his eyes.

Seeing this, Chen Yan pinched his hands and waved his hand, using a wind gathering technique, wanting to blow away the surrounding fog, but the strange thing is that this fog doesn't know how, Chen Yan's wind gathering technique used has little effect, and it didn't blow away much of the surrounding fog.

The speed of this demon beast was very fast, and as soon as Chen Yan finished using the Wind Gathering Technique, the demon beast had already come closer.

"Green rot crocodile", just now because of the fog, coupled with the speed of this demon beast is too fast, hidden in the silt of the swamp, and did not take a closer look, now this demon beast has surfaced, and only now Chen Yan has seen the true face of this demon beast.

This green rotting crocodile, most of its body is hidden in the mud, only the upper half of its body is exposed, I can't see how big it is, it is black and blue, and its body is covered with scale armor, which looks terrifying.

This green rot crocodile, in adulthood, has a first-order superb cultivation, extremely high defense, and extremely strong attack power.

What made Chen Yan pay attention was that at present, there was not one, but two crocodiles.

After the green rotting crocodile came to the shore, a huge mouth, that is, two black liquids flew towards Chen Yan and the others.

When the green rot crocodile came, Chen Yan immediately took out the high-level magic weapon, the trophy black flying sword, after releasing the Wind Gathering Technique.

Seeing the black liquid flying towards him, Chen Yan snorted coldly, and immediately raised his hand, and two or three fireballs flew towards him in a row.

Although Chen Yan couldn't instantly release more than twenty fireball techniques like the middle-aged man in armor before, he could still do it by releasing two or three.

This fireball technique is basically a spell that cultivators must learn when they get started, with Chen Yan's current cultivation at the ninth level of qi refining, it is not a problem to release two or three in an instant, but if you want to release more, you need time to prepare.

Although the middle-aged man in the armor had also prepared when he performed the fireball technique before, the time was too short, and it basically didn't take much time.

This green rot crocodile Chen Yan also knows a little, after entering the cultivation realm for so many years, Chen Yan usually spends most of his time reading various classics in addition to cultivating, so to speak, Chen Yan's written experience is not bad, but the difference is only actual actions.

One of the attacks of this green rot crocodile, this black liquid, which contains highly poisonous, is the most able to contaminate magic weapons, and the use of fireball attacks is undoubtedly the best.

The fireball technique released by Chen Yan and the black liquid of the green rot crocodile were opposite, and suddenly, the sound of "zi, zi", came, as the saying goes, water and fire are incompatible, this black liquid is also water-based, and when the two meet, bursts of smoke come out.

After Chen Yan released the fireball technique, he immediately sacrificed the black flying sword.

The two lumps of liquid spewed out by the green rot crocodile were solved by Chen Yan and Lin Xi effortlessly.

Chen Yan's flying sword slashed at one of the green rot crocodiles, and the next moment, Chen Yan's flying sword was immediately bounced out, and only a few scales fell from the green rot crocodile.

This made Chen Yan secretly frightened, the defense of this green rot crocodile was beyond his imagination, he used to see that the defense of this green rot crocodile was strong in books, but how strong it was, I don't know now.

And Lin Xi also summoned the previous group of wasps, but these wasps have little effect, they can only play a little harassing role, and they can't hurt the green rot crocodile at all, just with the thick scales of the green rot crocodile, Lin Xi's wasp swarm can't attack at all.

However, Lin Xi's summoning of the wasp swarm made the green rot crocodile furious, and he was helpless against these little things flying in the sky, and Lin Xi's wasp also attacked the eyes and other weaknesses of the green rot crocodile from time to time.
