Qinghe Immortal Clan.

The entrance of the cave is less than two feet in diameter and can only accommodate one person. It is pitch black and the bottom cannot be seen, but the spiritual energy coming out from inside is slightly stronger than that in the stone cave.

Song Qingyu had also keenly noticed this when he was searching close to here before, and discovered the hidden clues under the stone table.

Song Qingming looked at the bottom of the cave entrance, and said with some joy on his face: "The spiritual energy below is so rich, this should be the real cave where this senior is hiding!"

"I think so. The demon king just now was just a common spirit beast that seeks spirits and treasures. It has been hiding down here for so long, and it has actually cultivated to the middle stage of the Golden Core realm. It can be seen that this senior must have left a lot of good things down there.

There is nothing useful in this cave, so let's hurry up and go down to take a look!" Hearing this, He Mengxin nodded slightly in agreement.

Xia Mo, who was standing by, stared at the cave entrance carefully for a few seconds, without saying much, and quickly nodded in agreement with He Mengxin's proposal.

In order to prevent any dangerous monsters, or information about forbidden formations and mechanisms below, everyone was not in a hurry this time.

Song Qingming patted the spirit beast bag on his waist and directly summoned out several "Golden Fantasy Butterflies". He then commanded them to fly into the cave and explore it first.

After about a cup of tea, Song Qingming, who had kept his eyes closed, slowly opened his eyes and said to everyone with a smile: "About two hundred feet below, there is a larger space than here.

I looked around and didn't see any living creatures, nor did I come across any forbidden magic arrays. There shouldn't be any major danger down there."

"That's great! Let's go down first!" After Xia Mo finished speaking, a flash of light appeared under her feet and she jumped into the black hole in front of her, and soon disappeared from everyone's sight.

Immediately afterwards, He Mengxin and Song Qingyu jumped down one after another, and Song Qingming fell at the end.

After the four of them passed through a passage that was several hundred feet long, they soon landed on a very flat bluestone.

After taking a quick glance around, Song Qingming and his companions immediately showed some delight. The space below and the stone cave above looked almost the same on the surface, except that the space was slightly larger.

However, there are more spiritual objects placed around than above, and in the middle, there is a huge refining furnace that has not been used for a long time.

When they saw this refining furnace, they immediately understood that the magical instruments and treasures they had seen on it before should have been refined here by the owner of the cave.

He Mengxin stepped forward and took a look at the restriction under the furnace, and said in surprise:

“There is actually a high-level fire vein in this place. The cave owner chose to build a cave here, probably for this fire vein.

Fortunately, this person had sealed the underground fire below with a ban before leaving. Otherwise, no one has been here to guard it for so many years. Once the underground fire spreads up, all the spiritual objects in this cave will probably be reduced to ashes. "

When Song Qingming and Song Qingyu heard He Mengxin say that there was a high-level fire vein here, they both showed a hint of surprise.

The so-called fire vein is the favorite place of almost all alchemists and weapon refiners in the world of immortal cultivation.

In such a place, as long as one drills through the earth veins to draw out the earth fire in the veins, and then sets up formations and prohibitions to control the earth fire, one can use it for refining medicine and weapons all year round.

Using earth fire to refine spiritual objects is not only more stable and can increase the success rate of cultivators in refining spiritual objects, but it can also save cultivators a lot of spirit stones for purchasing fire-starting materials.

Low-level fire veins are not difficult to find. In Wei State, many immortal cultivation families above the foundation building stage have their own fire veins, which are used for the family's alchemy and refining.

After so many years of development, the Song family found a low-level fire vein of better quality on Mount Funiu, and built a family alchemy pavilion on it, which can barely allow the family monks to refine first- and second-level low-level elixirs and magical instruments.

Compared with low-level fire veins, mid-level fire veins of better quality are relatively rare. There are only a few sacred mountains in the entire Wei State combined, and most of them are controlled by the Xiaoyao Sect.

There is also a mid-level fire vein on Tuoyun Mountain, which was developed by Chen Jinliang in the past and is usually used for his own alchemy.

After Chen Jinliang passed away, there were no more alchemists above level three on Tuoyun Mountain, and they had not used the Fire Vein Lin Yutang much in recent years, so they simply opened it to all the cultivators on the mountain.

Anyone who wants to make pills or refine weapons can use that fire vein by spending some spirit stones.

Relying on this Jinyun Pavilion, not only did it attract many high-level alchemists and weapon refiners to settle in Tuoyun Mountain, but every year the Jinyun Pavilion also earned a lot of spirit stones for Lin Yutang and others by relying on this mid-level fire vein.

After Huang Siyuan advanced to the second-level alchemist, those who refined the second-level pills basically chose to use the intermediate-level fire vein in Tuoyun Mountain.

As for the rarer high-level fire veins, there is only one on Guyang Mountain in the entire Wei State, and it is basically controlled by the top leaders of the Xiaoyao Sect. Ordinary people rarely have the opportunity to use it.

Because Song Qingming was not a high-level alchemist or weapon refiner, although he joined the Xiaoyao Sect as a guest elder in recent years, he had never had the opportunity to use that high-level fire vein.

Although this high-level fire vein in front of them is extremely valuable, it is something that cannot be taken away. Everyone felt reluctant to take it away, but they could only sigh with regret.

However, although this high-level fire vein cannot be taken away, the third-level refining furnace on it can still be taken down.

A third-grade medium-quality refining furnace can be exchanged for about 20,000 spirit stones, which is considered a very good and precious spiritual object.

Song Qingming took action personally. He stepped forward and erased the restrictive runes on the refining furnace, then took down the third-level medium-grade refining furnace directly.

After putting away the refining furnace, the few of them left the fire vein and began searching for spiritual objects around the fire vein.

After searching around, they found three low-grade third-level magic weapons that had not yet been refined, and a book that recorded the refining heritage of high-level refiners on a stone table nearby.

After looking around and finding no useful spiritual objects around, Song Qingming and his companions turned around and went to the other side of the stone chamber.

Compared to the weapon refining place we just searched for, this place is obviously the place where the owner of the cave meditates and practices on a daily basis.

In the middle was placed a golden cushion emitting spiritual light. It was obvious that it was not an ordinary item and was quickly put into He Mengxin's storage magic tool.

Behind the futon there are two very conspicuous rows of stone shelves, on one side are placed various books and notes, and on the other side are bottles and jars used to store spiritual objects and elixirs.

However, compared to other places in the cave which are relatively neat, this area is much more messy.

Most of the jade bottles and porcelain jars placed on the stone shelf had been opened and were scattered all over the place. Many of them had fallen to the ground and broken into pieces. Even some of the things inside had deteriorated and turned into ashes.

On the ground next to one of the stone shelves, there was a spirit beast bag with a big hole bitten in it, and it was empty.

The gray rat demon king that Song Qingming and his friends encountered before should have escaped from this bag, if nothing unexpected happened.

Looking at the mess on the ground, everyone could guess that this was not done intentionally by the owner of the cave, but was caused by the gray rat demon king who ran out.

Because so much time had passed, many of the bottles containing spiritual objects on the shelves had basically been opened and devoured or damaged by the Gray Rat Demon King.

The four of them searched around on the shelves and found four or five bottles of ordinary spiritual objects that were still somewhat useful. The best of them was a bottle of third-level spiritual water, which could be of some use to Jindan cultivators.

On the other side, there were books and notebooks on the shelf. After everyone went forward to open them and took a look, they found that most of them contained ordinary low-level techniques in the world of immortal cultivation, or books recording various strange stories, elixirs and magical objects.

There were no high-level skills and secret techniques in the Jindan stage or Yuanying stage as they had imagined. For Jindan cultivators like Song Qingming, these books and notes did not have much useful value.

After searching for a while, everyone was surprised that they did not find the remains of the cave owner here, nor did they see any storage magic tools.

It seems that the owner of this cave did not pass away here, but left here for some unknown reason and never returned.

Just when everyone was feeling a little disappointed, Xia Mo, who was standing by, glanced at a corner of the stone chamber and was suddenly attracted by it. She immediately walked over quickly.

When Song Qingming and his companions saw this, they hurriedly followed, and soon they all arrived at a small pool in the corner.

This pool was obviously man-made, and was only about three or four feet in diameter. Spring water flowed inside it with a hint of deep blue, not the transparent color commonly seen outside.

There is also a light blue lotus with two halves of leaves in the middle of the pool. It doesn't look very eye-catching, and the spiritual energy contained in it is not particularly strong. It seems to be just an ordinary low-level spiritual medicine.

"This is a crystal lotus. It looks like it's mature!"

Seeing this plain-looking light blue lotus, He Mengxin on the side shouted out with joy.

Seeing He Mengxin was so excited after seeing this thing, Song Qingming was also slightly surprised, and hurriedly asked softly:
"I have heard of the name Crystal Lotus before. Although I have never seen it in person, I know that it is a fourth-level spiritual medicine. How can Fellow Daoist He confirm that the spiritual object in the pond is the Crystal Lotus?"

Song Qingming has been practicing Taoism for more than a hundred years, and has read many books and notes describing various high-level spiritual medicines in the world of immortal cultivation, among which there are records about high-level spiritual medicines such as crystal lotus. This thing can be used to refine several high-level spiritual pills, but it is also very rare and difficult to cultivate to maturity. Even the spiritual medicine gardens of large Yuanying sects such as Xiaoyao Sect do not grow this kind of spiritual medicine. "

When the crystal lotus matures, it can become a precious elixir that reaches the fourth level. However, it does not seem consistent with the unprepossessing blue lotus in front of me.

Seeing that Song Qingming and Song Qingyu both looked at him curiously, He Mengxin explained:

“This thing is indeed a crystal lotus. The reason why I recognize it is because we happen to have cultivated several similar spiritual medicines in our Baihua Palace spiritual medicine garden, but they are not yet fully mature.

Once this crystal lotus matures, it will automatically hide its own aura. It is normal for you to misunderstand it when you see it. If I had not helped cultivate and care for this kind of spiritual medicine several times in the sect's spiritual medicine garden, I would never have recognized it at a glance.

"Junior Sister Liu is right. This crystal lotus has matured, but it has not been eaten by the monster. This may be the reason."

As soon as Xia Mo finished speaking, a flash of spiritual light appeared in her hand, and she used her own magic power to transform into a giant hand, which directly grabbed the "Crystal Lotus" in the pool and wanted to pull it out of the pool directly.

As soon as the giant hand touched the "Crystal Lotus", a blue light immediately lit up on the petals, which originally looked plain and ordinary, and emitted a very powerful spiritual energy.

"It really is a fourth-level spiritual medicine. I never thought we would have such an opportunity!"

After feeling the aura and pressure emanating from the "Crystal Lotus" at this moment, Song Qingming, who saw the true appearance of this thing, couldn't help but exclaimed.

Not only Song Qingming, but Song Qingyu and He Mengxin on the side were also very excited when they saw this scene.

If spiritual medicines above level three are considered to be something that can be encountered by chance but not sought after, then spiritual medicines of level four are truly high-level spiritual objects that most ordinary cultivators will never have the chance to see in their lifetime.

Song Qingming had never seen a fourth-level spiritual medicine before, even at the top auction near the Floating Cloud Mountains, such as the Star Conference. It can be seen that the value of a fourth-level spiritual medicine can no longer be measured by spirit stones.

Song Qingming estimated that if this "Crystal Lotus" was taken to a large auction house, it should be able to easily fetch a sky-high price of around 100,000 spirit stones if nothing unexpected happened.

The last time he went to the "Tower of Babel", Song Qingming only brought out a few third-level lower-grade spiritual medicines. He didn't even see a single third-level upper-grade spiritual medicine, let alone spiritual medicines above level four.

As the magic power in Xia Mo's hands surged, the blue light on the "Crystal Lotus" became brighter and brighter, and soon the entire stone cave was illuminated.

A moment later, the giant hand in front of Xia Mo pulled up the pearl elixir and directly took the "Crystal Lotus" into its hand. The blue light on the elixir as soon as it was in its hand quickly went out, leaving only a faint layer of spiritual light.

Before Song Qingming and the others could step forward to take a closer look at the item, Xia Mo's hand flashed with a flash of light, and a black wooden box immediately appeared. She carefully put the precious elixir into the box and put it away.

“Spiritual medicines above level four, when mature, can cause strange phenomena in heaven and earth. It seems that our previous judgment was wrong. The colorful rays of light that appeared nearby were not caused by the monster’s breakthrough, but by this crystal lotus.

When we were picking herbs just now, we triggered a strange phenomenon in the heaven and earth. I am afraid that it will attract those low-level monsters. In order to prevent any changes, we should not stay here for long. We should hurry up to search for spiritual objects and leave quickly!"

After hearing Xia Mo's analysis, Song Qingming and the others immediately felt that it made sense. They nodded in response and began to search the remaining corners of the cave to see if there were any spiritual objects that they had missed.

After obtaining a fourth-level spiritual medicine called "Crystal Lotus", Song Qingming and others suddenly became excited, and a smile appeared on their faces.

Although the results of this trip were average and the Nascent Soul predecessor's relics that everyone wanted the most were not found, several third-level spiritual objects were found, plus the extremely precious fourth-level spiritual medicine "Crystal Lotus". For Song Qingming and others, the trip was worthwhile.

However, after finding the "Crystal Lotus", the cave below had almost been searched by everyone, and there was nothing useful in the remaining corners.

After searching the area nearby and finding nothing, He Mengxin returned to the pool and took out a small jade bottle. She walked up to the pool, scooped up the blue liquid from the bottle, and then brought it to her nose and smelled it.

"It's really the Ice Crystal Jade Liquid. No wonder it can cultivate a mature crystal lotus. It seems that this senior has also spent a lot of thought on these two spiritual medicines."

He Mengxin smiled and muttered to herself, took out a dozen jade bottles, and began to collect the blue liquid from the pool.

Seeing He Mengxin filling the bottle with spiritual water and walking around it, Song Qingming, who also didn't get anything, walked over with some curiosity.

"Fellow Daoist He, what exactly is this spiritual water? What magical uses does it have?"

Seeing that Song Qingming seemed to be interested in the spiritual water in the pool, He Mengxin quickly smiled and explained: "This thing is called Ice Crystal Jade Liquid. Although it is not a precious high-level spiritual water, it is also a rare spiritual water in the world.

This ice crystal jade liquid can be used to cultivate spiritual medicines, or it can be directly used to feed low-level spiritual beasts. The reason why the demon king was able to successfully cultivate to the Golden Core realm was probably because he swallowed a large amount of ice crystal jade liquid.

There is still a lot of spiritual water in this pond. If you are interested, you can take some back. Your Song family has also planted a lot of spiritual herbs, so there will always be a chance to use them."

Hearing what He Mengxin said, Song Qingming's face lit up with joy. He immediately took out several larger pottery jars from his body and began to collect the "Ice Crystal Jade Liquid" from the pool.

He Mengxin is a second-level top-grade spiritual plant master. She wants this "Ice Crystal Jade Liquid" naturally in order to use it to cultivate spiritual medicines in the future.

Song Qingming didn't find anything good, and based on the principle of not wanting to waste anything, he wanted to take all the extra spiritual water back.

According to He Mengxin's introduction, regardless of whether these "Ice Crystal Jade Liquids" are valuable or not, they are at least quite useful. Using them to feed the Sky Fire Peng at home may help it advance to the late stage of foundation building sooner.

Xia Mo, who was standing by, saw what Song Qingming and the others were doing, but she didn't care about the spiritual water in the pool, nor did she urge Song Qingming and the others.

After walking around and not finding any spiritual objects, he walked alone to the middle location where the earth fire was sealed and carefully studied the formation restrictions on it.

Song Qingyu ran to the stone shelf again and searched through the bottles and jars that had already been searched by everyone.

"Hey! Why is there another magic weapon here?"

Song Qingyu, who was searching the stone shelf carefully, suddenly caught a glimpse of a flying sword inserted in a depression on the mountain wall behind the stone shelf. His attention was immediately attracted.

The entire blade of the flying sword had sunk into the stone wall, with only a small section of the hilt left outside. Judging from the remaining aura on it, it was not of high grade and did not seem to be a third-level magic weapon.

Because the color of the end of the hilt is the same as the mountain wall, and it is blocked by the stone shelf, it would be difficult to notice it if Song Qingyu hadn't searched the place carefully and persistently.

After carefully moving the stone shelf away, Song Qingyu wrapped two fingers of his right hand with a layer of magic power and directly clamped them on the hilt of the sword. He tried hard to pull the flying sword out of the stone wall.

Somewhat to her surprise, the flying sword seemed to be inserted a little too deeply into the stone wall. It only moved slightly and was not pulled out directly by Song Qingyu.

Seeing that the flying sword was inserted so tightly, Song Qingyu also felt a little strange.

If it was a magic weapon that was difficult to drive with her cultivation level, it would be fine. But it was just an ordinary magic weapon, even if it was a second-level top-grade magic weapon, Song Qingyu should be able to pull it out easily.

However, because of the temporary increase in magic power from the elixir he had taken earlier, Song Qingyu was still a little weak at the moment, and did not use much of his magic power at the beginning.

Seeing that he couldn't pull it out, Song Qingyu felt a little depressed. He immediately increased the magic power in his hand, gripped the hilt of the sword with all his strength and pulled it out with all his strength.

After a while, only the sound of friction between the flying sword and the mountain wall was heard. After some effort by Song Qingyu, she finally took the flying sword out of the stone wall.

"What kind of material is this magical weapon made of? Why is it so heavy?"

After pulling out the flying sword, Song Qingyu looked at the sword in his hand carefully with joy, and then a hint of disappointment appeared on his face.

Judging from the aura, the flying sword in Song Qingyu's hand should also be a second-level magic weapon, but it seems that it is not completed yet, and even the blade has not been opened yet. It is just a semi-finished magic weapon.

"This is really strange. Why would you put this semi-finished magical tool here instead of putting it in the refining furnace to continue forging it?"

Song Qingyu, holding the flying sword, thought for a moment, but still couldn't figure it out. He could only shake his head and wanted to put the flying sword away first.

Although this flying sword is a semi-finished product, its weight in the hand is obviously much heavier than other magical weapons. Even the second-level top-grade flying sword she has is far lighter than this. If it is refined, it should also be a second-level magical weapon.

Take it back and let Song Yuanfang and the others study it. Maybe it can be modified into a second-level magic weapon. Even if it is directly melted into materials, it can still be worth some spirit stones. There is no need to discard it directly.

Just when Song Qingyu was casting the spell of controlling objects and wanted to put the flying sword in his hand into the storage bag on his waist, something unexpected happened to Song Qingyu again.

The flying sword had just been wrapped by the magic power released by Song Qingyu, when suddenly a beam of white light flew out of it and sank directly into the space between Song Qingyu's eyebrows. (End of this chapter)
