"Ancient crystal stone."

Lin Xuan was stunned, obviously this answer was beyond his expectation.

"Yes, the best crystal stones have no effect. However, ancient crystal stones are originally something that can be encountered but cannot be sought. I and my disciples have searched all over the place, but it is difficult to find anything." Shi Xianzi's anxious voice spread.

He heard it and peeked at Lin Xuan's face while talking.

Apparently she was afraid that Lin Xuan would blame her for this.

However, there was no trace of anger on Lin Xuan's face. Instead, he put his hand on his forehead with a thoughtful look on his face: "Ancient crystal stone, well, this thing is indeed not available in the market. It doesn't matter.

Fellow Daoist Xu, please take me to see the formation later, Lin has his own idea."

"Of course...there is no problem."

Lin Xuan did not get angry, but instead gave such an order, which shocked both the handsome man and Shi Xianzi, but naturally they did not dare to object and hurriedly agreed.

"Senior, please follow me."

Then the two of them led the way, and Lin Xuan flew out with them. The Small Xuyan Qiankun Formation was not arranged here, but chose another hidden place.

…

The three people escaped from the light very quickly, and the journey, which was quite far away, took less than half a day.

This is a desert, but there are some rolling mountains, and the spiritual energy is sparse, making it an inaccessible place.

"Senior, this is it."

The three people escaped from the light for a moment and slowly landed.

Lin Xuan looked at the surrounding barren hills. On the surface, they looked unremarkable.

Even if a cultivator happened to pass by here, it would be difficult to find anything wrong.

However, Lin Xuan was not an ordinary cultivator. A silver light flashed in his eyes, and he naturally found some arrangements that interested him.

"Yes. Yes, fellow Taoist is indeed a well-known master of formations. The illusion formation he arranged was so mysterious that he almost deceived even Lin." Lin Xuan's approving voice reached his ears.

"Senior is laughing. I just don't want people to discover the secret of Xiaoxu Qiankun Formation, so I have placed some illusion restrictions around here. It's not worth mentioning."

The big man in brocade robes saluted quickly. Although he spoke in an understatement, deep down in his heart, he was horrified.

This illusion prohibition that conceals all kinds of magic is his proud work. He originally thought that even an immortal cultivator at the level of transcending tribulation would have a hard time seeing through it, but he didn't expect that he would see through it at a glance.

Is the consciousness of the old monster in the Tribulation Stage really that strong?

While the other party was surprised, the expression on his face naturally became more respectful.

"lead the way!"

Lin Xuan's face didn't look strange at all. He just waved his hand and gave the order.

"yes!"

The big man in brocade clothes did not dare to neglect, he stretched out his hand and patted it on his waist. With a flash of inspiration, he took out a palm-sized formation plate from the storage bag on his waist.

The shape is simple and simple, and Lin Xuan couldn't tell for a moment what material it was made of.

But it’s obviously not a mortal thing!

Then he saw the opponent waving his hands and firing out spells one after another as fast as lightning.

"break!"

As he shouted loudly, the plates began to spin.

A "pop" sound reached my ears, and a beam of light as thick as an arm shot out from its surface. It disappeared in a flash and disappeared into the void.

Then the originally calm air began to ripple like a small lake with stones thrown into it.

The original scenery also became blurry, as if a picture scroll had been torn apart. After a few breaths, it returned to nothingness. However, the scenery was completely different from just now.

The desert is still a desert, but the rolling hills are gone.

It was replaced by an oasis, about dozens of acres, and the spiritual energy was obviously much richer than before.

Lin Xuan also had a look of admiration on his face. He used Tianfeng Divine Eye just now. Although he could see at a glance that the other party had cast an illusion nearby, but the specific situation could not be seen immediately. Now it seems that the other party has withdrawn the restriction.

, it is indeed much more mysterious than I imagined.

As the saying goes, there is no illusion under a great reputation. As a formation master, the other party is indeed worthy of his reputation.

"Senior, please."

"Um."

Lin Xuan did not hesitate, and in a flash, he flew past the oasis.

There is a piece of grass inside, and a complicated formation on the grass is extremely conspicuous. Lin Xuan, a small Xuyan Qiankun formation, has also understood it, and he can recognize it at a glance.

“It’s really good!”

As the saying goes, hearing is false, seeing is believing. Lin Xuan glanced at it and saw that the entire formation had been laid out, with several prominent grooves left on it. Needless to say, they were used for inlaying crystal stones.

"Senior, we have tried various levels of crystals, but they are completely useless. According to the junior's speculation, only ancient crystals can activate this formation." The respectful voice of the man in brocade came into his ears.

With a bit of helplessness.

"Oh, do you have any requirements for the level of crystal stones?" Lin Xuan asked like this.

"This junior doesn't know this, but since this formation has the effect of shattering the void, low-level crystals are probably useless, and only top-quality crystals are needed." The big man Jin Yi said blankly.

This is what makes him feel powerless. Ancient crystal stones are originally treasures that can be encountered but cannot be found. Fortunately, it is a lost interface here. If it is a coincidence, occasionally you can find some related treasures.

But most of the time, they are just low-level crystals. How can they get the best ancient crystals?

Even the ancestors in the Tribulation Stage have mostly only heard about it.

However, after Lin Xuan received his answer, there was no embarrassment on his face.

There was even a smile on the corner of his mouth.

As the saying goes, there is no coincidence, and it is extremely applicable to me. If I hadn't gone out to hunt for treasure this time, I really wouldn't have been able to get the ancient crystal stones. However, now, I have a lot of them in my storage bag.

Lin Xuan was not interested in explaining to the two of them anymore. He flicked his sleeves and robes, and the spiritual light flickered. When the light converged, more than ten crystal stones the size of date pits appeared in front of his eyes.

"Well, these are enough for fellow Taoists." Lin Xuanyun said calmly.

"That's enough, that's enough."

The big man in brocade and the woman surnamed Shi were already dumbfounded. Although Lin Xuan asked them to bring him here, the two of them had already made some guesses. But seeing Lin Xuan take out so many ancient crystals so easily, they were still stunned.

It surprised the two of them.

Lin Xuan became more and more unfathomable in their eyes.

If I am not mistaken, the person in front of me is probably not an ordinary ancestor who has transcended the tribulation period.

The big man in brocade clothes did not dare to neglect it more and more. Over the years, he had already mastered the Xiaoxu Qiankun Formation, but it could not be activated because it was missing the ancient crystal stone.

Now that I have obtained this object, there is no hesitation at all. I raised my hands and summoned the crystal stones. The next movement was like flowing clouds and water, and all the more than ten crystal stones were embedded in the formation.
