After the spiritual power was infused, this spiritual sword became extremely sharp, and with a slight movement, it was inserted into the stone wall, and with a slight stirring of both hands, a stone about half the size of a person was cut off.

Xiao Chen put the stone aside, looked at the black rumbling cave in front of him, his face showed a little hesitation, and then his eyes condensed slightly, revealing a determined color. Walk towards the cave.

The light in the cave was extremely dim, and Xiao Chen used the weak spiritual power in his body to his eyes, and he could only see the road ahead in front of him, groping all the way and slowly moving forward.

Deeper than ten zhang deep, Xiao Chen's footsteps suddenly paused, picked up his hand from the mountain and twisted it, feeling a little damp breath, his face couldn't help but show a little surprise, and whispered: "Is there still an underground tunnel here?"

Walking forward, he went deeper than ten zhang again, and the humidity in the air became heavier, and when he turned a corner, there was really a little sound of water flowing in his ears.

At the same time, an extremely faint medicinal fragrance also followed.

"Hmm, the smell of the blue lotus?" Xiao Chen's face suddenly showed a look of surprise. He stayed in the Elixir Valley for a few days, although he had not learned the slightest alchemy skill, but when he helped the outer disciples to clean up the elixir, he also wrote down a few more cherished spiritual herbs, and this blue lotus flower happened to be one of them.

"No, the scent of the lotus flower is slightly sweet, although the smell is very similar, but it is slightly sour, it seems that it should be the smell of some kind of wild grass. Xiao Chen smiled and shook his head, this blue lotus flower is extremely precious, it can be used to refine more than ten kinds of cherished elixirs, how can it be seen everywhere.

But at this moment, Xiao Chen couldn't help but feel a little curious in his heart, stretched his neck to look ahead, and the black rumbling didn't see it really, so he continued to walk towards the source of the sound of the water.

"Wow" "Wow" "Wow"

The sound of the water is getting closer and closer, and the medicinal fragrance in the air is also enhanced, and there can't help but have the blue lotus, and even the smell of high-grade spiritual grasses such as Tieqing Vine, Jin Zhicao and He Shou Wu are also mixed in, which makes people feel a shock and comfort all over their bodies when they take a deep breath.

Xiao Chen's feet unconsciously quickened his pace, and when he walked along the stone cave to the end, he found that there was a dead end in front of him, but in the clear flowing water, it was faintly coming from behind this stone wall. Xiao Chen stretched out his hand and knocked on the stone wall, and suddenly made a "bang" and "bang" sound.

"Fortunately, this stone wall should not be thick. Xiao Chen breathed a sigh of relief, reached out and took out the spirit sword from the storage bag again, and under the infusion of mana, he exerted everything against the stone wall in front of him. Like a knife cutting tofu, a hole that can accommodate ordinary people to enter and exit is dug out.

As the stones fell, a bright light suddenly came out of the stone cave*, Xiao Chen stretched out his hand to block it, and looked inward with his eyes. But before he could poke his head into the cave, a strong and extremely strong medicinal fragrance instantly escaped from the hollow.

"Ahem!!Ahem!!" The tip of his nose took a sip, Xiao Chen's face suddenly couldn't help but turn red, and he coughed violently reflexively. The richness of this medicinal fragrance is really beyond the imagination of ordinary people, it seems that dozens or hundreds of spiritual grasses are mixed together, and then sealed and allowed to grow, and after dozens or even hundreds of years of precipitation and accumulation, it can reach such a point.

Although Xiao Chen's face was flushed from a violent cough, his dark eyes were instantly filled with ecstasy! This time, this rich medicinal fragrance entered his nose, although it made him suffer a little, but it also made him instantly certain that there were definitely dozens or hundreds of spiritual grasses growing in the grotto in front of him, and its growth year was definitely not low! Because when he inhaled the medicinal fragrance just now, although the medicinal fragrance was mottled, the spicy smell could not be concealed!

"Broken Intestine Grass!" the corners of Xiao Chen's mouth curled, revealing a happy look. This smell was definitely emanating from this highly poisonous spirit grass that killed people between the breaths! Moreover, this spicy smell was so strong that it far exceeded the hundred-year-old Broken Intestine Grass that Xiao Chen had seen in the Elixir Valley, which showed that its growth year was extremely long!

After a while, Xiao Chen suppressed the heat in his heart, and when the medicinal fragrance dissipated slightly, he covered his mouth and nose with the sleeves of his robe and stepped into it.

The faint fluorescence emitted from the surrounding stone walls made him feel uncomfortable for a short time, and when his eyes returned to see the scene in front of him, Xiao Chen's mouth couldn't help but open slightly, and his eyes were full of shock.

I saw that the grotto behind the stone wall was about hundreds of zhang in size, and there was a strange crystal with a light white color on the surface of the stone wall, and this faint light was emitted from this crystal. There is a crack above the grotto, and the Juanjuan water flows down from it. The water fell on the ground, and after an unknown amount of impact, the little sediment carried formed a delta of about 20 zhang in the grotto, on which countless kinds of spiritual grasses were born in a mess. The water flows slowly over the delta and then flows in a small pool at the back. This pool is supposed to be connected to the underground waterway, so the water is extremely clear, but it is dark and you can't see the bottom, and you don't know how deep it is.

Xiao Chen's gaze slowly swept from this grotto, and he hurriedly closed his eyes tightly, and took more than a dozen deep breaths in succession, only then did he barely suppress the thought in his heart that wanted to yell and scream!

Two hundred years of He Shou Wu!

300 years of golden grass!

400 years of honeysuckle!

Three hundred years of iron green ivy!

Looking at the heavy spiritual grass growing like weeds in this grotto, Xiao Chen almost had a feeling of being in a dream!

After a long time, he slowly calmed down, his brows furrowed slightly, and he couldn't help but show a little hesitation.

"Why is there so much spiritual grass growing in the belly of this mountain, and how can they survive in such a place?"

But at this moment, Xiao Chen's eyes fell on the strange crystal on the stone wall, his complexion suddenly changed slightly, and then he slowly closed his eyes, and the "Grass and Tree Biochemical Technique" in his body slowly operated, and the next moment, his eyes widened in shock, and only after half a sound did two words pop out of his mouth, "Spirit vein!"

In this grotto, the abundance of spiritual power is much higher than that of the outside world, and even the medicine garden where the medicinal herbs are cultivated is much richer! In this way, there is only one explanation, that is, under this grotto, there is a small section of spiritual veins hidden! This spiritual vein is definitely not big, even only a few meters in size, otherwise it must have been noticed by the monks in the sect that this place is abnormal, and they would not be able to wait until it was discovered by Xiao Chen. And the fluorescent crystals on this stone wall also have an explanation, they must be because they have been eroded by the aura for a long time, and gradually transformed, if it is hundreds of thousands of years, they may even become real spirit stones.

But even if the reason for the survival of these spirit grasses is found, where do these spirit grass seeds come from? Could it be that they could not be born out of thin air?

Xiao Chen's gaze swept over the grotto, then he condensed slightly, and walked quickly to the top of the water, his eyes fell sharply on the clear flowing water, as if he was looking for something. After a while, his eyes suddenly lit up, and he put his hand into the water and grabbed it, and a cyan, slightly flattened seed was instantly held in his hand. His eyes fell on this, and Xiao Chen suddenly remembered that it seemed that there was only one living water flowing down from the mountain in the entire Luoyun Valley, and it happened to flow out not far from his medicine garden. Thinking about it this way, there is only this one water source available for all the medicine gardens in the sect! Looking at the seeds in his hand, the corners of Xiao Chen's mouth slowly showed a little smile, and then quickly spread to his entire face, and he whispered in his mouth: "Creation, creation! This is my Xiao Chen's creation!"

The water used by the countless medicine gardens in the Falling Cloud Valley was that the spring water needed to be introduced into the medicine garden, and in this way, the mature spirit grass occasionally fell into the water flow and was washed away by it. However, this water flow happened to flow into the grotto along the cracks in the mountain, and there happened to be a small spiritual vein in the grotto. Under such a coincidence, a medicine garden hidden in this grotto was born!

。。。。。

Half a day later, Xiao Chen still returned from the grotto, although this abandoned medicine garden was extremely remote and few people passed by, but just in case, Xiao Chen still put the stone back in its place, and then arranged some weeds and stones outside at random, until he was sure that no one would notice, then he nodded with satisfaction.

"I thought it was an abandoned place, but it was a place to make people. Who would have thought that there was a huge opportunity hidden in this abandoned medicine garden!"

"That Tianhua originally meant to harm me, but I didn't expect it to give me a creation!"

Xiao Chen looked up and smiled, things in this world are so wonderful, if he was known by that Tianhua at this time, he would definitely be so angry that he vomited blood and died on the spot.

After a while, Xiao Chen's mind calmed down, and he muttered: "Although the location of the medicine garden is extremely remote, in order to prevent accidents, some simple prohibitions should also be placed outside the valley, even if it can't prevent people from entering, but it can play an early warning role, but it is enough." ”

Yao Daozi is extremely good to him, a registered disciple, although he has not taught it personally, but all kinds of junior jade slips have never been stingy, and this "Formation Foundation Chapter" happens to be among them.

Xiao Chen made up his mind in his heart, so he hurriedly returned to the stone house, took out the jade slip from the storage bag, and put it on his forehead to learn about it.
