In fact, among the monks of the same level, Lin Xuan's number of treasures was already jaw-dropping, and other monks in the middle stage of foundation building had a high-grade spiritual weapon, which was already very remarkable, and Lin Xuan's top-grade spiritual weapon had several pieces.

But he often encountered opponents who were higher than his own realm, and compared to them, Lin Xuan was dwarfed.

The Bixue Ring has already been given, and Wu Hook is already a top-grade spiritual weapon from the head of the Fire Spirit, and if you want to strengthen its power, it is an effective way to enter the Mother of Dark Iron inside

But the Mother of Xuantie is the material for refining magic weapons, and it is a monk in the Ning Dan period, and it is also regarded as a treasure, and the cultivators in the foundation building period have never even seen it.

But there is exactly one in the page of the book in front of me.

Lin Xuan pondered for a moment, took it in his hand, and came to the alchemy room, a magic trick was played, and the beast head on the ground burst out of the raging leyline fire.

Elixir Mountain is famous for alchemy, but in fact, there are a lot of miscellaneous studies, and there is also some involvement in making weapons, so it is not surprising that this technique and alchemy have a lot in common.

Lin Xuan had also read books on this subject, of course, with his current level, it was absolutely impossible to refine a spiritual weapon, but there should be no problem in separating and refining the materials. ^^ Lin Xuan pinched the sword technique in his hand, and a levitation technique hit the ancient book of "Heavenly Thunder Decision", and then used his divine sense to control the fire of the leylines, and began to slowly refine the suspended pages.

A few hours later. Lin Xuan waved with an ugly face. The ancient book flew back into his palm.

Spread out in front of him, after carefully examining it, Lin Xuan's expression became more and more gloomy, the fire of the leyline, to say the least, is thousands of degrees, but it has been calcined for so long. The book has not been melted down in the slightest.

No wonder Na Lei Ao once said that this book is not in, and the spirit weapon is difficult to hurt. He tried all the tricks, but he couldn't separate the Mother of Darkiron.

Lin Xuan is now a mixed bag.

Happily, the material for refining the magic weapon really lives up to its name.

The depressed thing is to use his own means and only dry eyes.

What to do?

Lin Xuan frowned slightly, his fingers lightly tapped on his knees, in fact, it was not without a choice in front of him, such as asking for help from Tong Yu Zhenren.

Although his own teacher is only a cultivator in the foundation building period in name, he has known that the Dao elixir mountain is secret. Lin Xuan didn't see it that way.

To be able to become the head of this sect that has been inherited for thousands of years and has a huge hidden strength, Tongyu Zhenren's cultivation will definitely not be only on the surface.

Although it cannot be confirmed. But Lin Xuan was sure that he had entered the Ning Dan stage.

To separate the Mother of Darkiron, you must first melt the book.

The leyline fire can't do this, but the three-flavor true fire of the Ning Dan stage cultivator should be a breeze.

But Lin Xuan didn't plan to ask for help from him, because he had too many secrets.

Shook his head. Lin Xuan was about to put the ancient books in his hand into the storage bracelet, but suddenly stopped, and a strange look appeared on his face.

At this time, his expression was very incomprehensible, suddenly smiling, suddenly solemn, suddenly distressed, and even a little eager to try, as if he had seen something difficult to choose.

Half ringing. Lin Xuan gritted his teeth. No longer hesitate to sit down cross-legged.

With both hands stretched out in front of his chest, he sandwiched the ancient book of "Heavenly Thunder Decision" between his palms and fingers. Then he took a breath and began to drive the blue light spots in his body.

Lin Xuan suddenly had an idea, since his Star Sea ability could isolate the elixir and the impurities in the herbs, could he also purify other materials.

For example, the Mother of Dark Iron in the pages of ancient books!

This is a very bold idea, to be honest, Lin Xuan is not sure at all, he has to give it a try to know the result.

Lin Xuan cautiously started to do it, after all, it was the first time to try, and he knew that this was definitely much more difficult than purifying the pill.

The night passed quickly.

Lin Xuan opened his eyes, stood up from the ground, and moved his somewhat sore body, the expression on his face could not show joy or anger.

After trying last night, he didn't know whether to be happy or depressed.

Well, overall, it's still a lot of excitement.

Although Lin Xuan had not separated the Mother of Xuantie, this was not to say that his assumption was wrong, on the contrary, this line of thinking was completely feasible.

Blue Xinghai's ability is purification, in addition to the elixir, the material can also be purified through the method of separating impurities, and the parts that need to be purified.

In other words, theoretically, Lin Xuan could completely get the Mother of Xuantie out of the pages of ancient books through the Blue Star Sea.

But...... How to say it, it was still his lack of cultivation, the volume of the Blue Star Sea was directly proportional to the mana, and with Lin Xuan's current strength in the third layer of the foundation building stage, he could not smoothly separate the Mother of Xuantie.

Lin Xuan was surprised to find that every time he moved, the light points consumed were more than a thousand times that of the purified pill.

I didn't expect it to be so difficult to purify the materials of the device, it seems that before entering the Ning Dan period, this is also an ability that can be seen, but can only be greedy.

Lin Xuan smiled bitterly.

However, after being depressed, he let go of his mind again, after all, this is also a great and significant discovery, although it is not needed now, but it will be beneficial in the future.

You must know that after the monk enters the Ning Dan period, he uses the magic weapon.

And the magic weapon and the spirit weapon are completely different, the materials for refining are extremely rare, and many cultivators in the Ning Dan period have not been able to collect all the strength of their lives, so in the cultivation world, there is such a saying:

"It's hard to condense the pill, and it's even more difficult to get the magic weapon after condensing into the golden pill. \

It is by no means an exaggeration, but the reality of today's cultivation realm.

Although it seems too far to consider these now, with the discovery that Xinghai can purify the materials of the craft, it is still very useful.

After entering the Ning Dan Period, it is much easier to find the materials for refining the magic weapon by yourself, except for a few raw materials similar to the Mother of Dark Iron, many other materials can be purified from some common things.

Although he couldn't use it for the time being, Lin Xuan didn't put the ancient books into the storage bracelet, but read them slowly.

"Heavenly Thunder Decision" is just a technique of the fourth-rate sect of the Thunder Sword Sect, and it stands to reason that it is useless for Lin Xuan, who has the Nine Heavens Xuangong.

But after Lin Xuan thought about it, he felt that there was something strange about this matter.

Think, if it is really a fourth-rate garbage exercise, will it be preserved with an ancient book that has been added to the Mother of Xuantie, just engrave it in the jade cylinder, so solemn, Lin Xuan doesn't think that the Thunder Sword Sect is the ancestor is full of food, there must be another mystery in it.

An hour later, Lin Xuan put down the book.

There is no gain.

He read the Heavenly Thunder Decisive several times over and over again, and it was indeed a very ordinary exercise, and he really didn't see anything strange.

Lin Xuan's face was gloomy, but later, he calmed down and said to himself: "This book has also been passed down in the Thunder Sword Sect for hundreds of years, if the secret is really so easy to see, it would have been discovered by the disciples in the sect a long time ago, and this matter is not in a hurry." ”

After thinking about it like this, I feel a lot better.

After putting away the ancient books, Lin Xuan rested for two days to relax his body and mind, and then began to cultivate.

A few days later, Lin Xuan came out of the cave mansion, closed the door and put a ban on it, and then he left the elixir mountain and flew away in the southeast direction.

Speaking of this trip, it was purely accidental.

Originally, Lin Xuan planned to let his cultivation go up two more steps in one go, enter the late stage of foundation building, and then he could refine the Xuanhuo Divine Bead.

Before practicing, Lin Xuan took out the piece of jade pendant that he had obtained from the stream.

So far, Lin Xuan has only figured out one of its functions, which is to replenish the spirit energy in the Beast Soul Talisman.

When he first discovered this, Lin Xuan was excited, because it meant that he could use something as practical and powerful as the Beast Soul Talisman without any scruples.

In the battle with the Yin Ghost Venerable, Tianxiang Bird's soul energy was consumed a lot, so Lin Xuan planned to replenish it with a jade pendant like last time.

But what made him jaw-dropping happened, but it didn't work.

Could it be that last time it was an illusion, Lin Xuan was a little dumbfounded.

However, after calming down and studying it carefully, I finally found the reason.

Jade Perry's energy is not out of thin air, you need to find the demon beast first, absorb its soul, and then replenish it into the beast soul talisman.

For example, last time in the Biyun Yam Garden, Yu Pei was able to replenish the Tianxiang Bird because he absorbed some of the soul energy of the third-level demon beast

To put it simply, it acts like a charger.

After figuring this out, Lin Xuan really thought about it for a while, and finally decided to go out to look for demon beasts.

After all, if you want to cultivate to the late stage of foundation building, it is not something that can be completed in one or two years.

And now that there is not much energy left in the Beast Soul Talisman, if you encounter a strong enemy again, your strength will be greatly reduced.

Although logically speaking, it is unlikely that this situation will occur if you are in retreat in the cave of the Elixir Mountain, but as the saying goes, there is nothing wrong with being careful!
