After searching for a long time, An Yun finally found a wonderful place in the back mountain.

It is about twenty miles away from the main hall of Chaoyun Sect, there are rolling low hills, and the ground is dense with low forests. The vegetation here is so lush because it is an abandoned spiritual vein mine, and under the hills, there is a labyrinth of mining caves.

Although there are no spirit stones in the cave, the remaining spiritual energy is still there, making the spiritual energy here much thicker than other places. Moreover, as a spiritual stone vein mine, this place was forbidden by the power of the previous Chaoyun Sect to isolate the aura, and after it was abandoned, the prohibition still existed, which could effectively isolate the monk's divine consciousness exploration.

An Yun came to the entrance of the mine, did not stop, and went directly into the mine.

The air in the cave is turbid, the dust is everywhere, and there is a wind lamp every three zhang on the cave wall, all of which are extinguished at this time.

An Yun released a spiritual fire technique, ignited a wind lamp in front of him, and rubbed it, the wind lamps on the cave wall lit up one after another, instantly illuminating the mine.

Suddenly, a gust of wind blew in, and there were many thin screams mixed in the wind. A transparent shield appeared on An Yun's body, blocking the stench and wind from the shop. When I looked up, it turned out to be a group of bats hanging upside down on the roof of the cave.

An Yun looked at the thick layer of luminous sand falling on the ground, and his brows furrowed. Thinking that there might be more small animals such as bats or rats inside, he simply reached out and pinched the trick, and the spiritual power of the dantian quickly worked.

"Xue Ji."

Xue Ji is a spell recorded in the second volume of the Guiru Treasure Book, practiced to a high depth, thousands of miles of snow.

Fluffy snowflakes suddenly floated around her, and the snowflakes had hexagonal ice cubes, gathering more and more, and after a few moments, they wrapped her in the snow.

An Yun pinched the trick and pointed forward, and countless snowflakes spun rapidly, like countless spinning small flying knives, flying slowly in the direction she pointed.

The bats in the cave screamed and fled, and soon disappeared cleanly, but countless swirling snowflakes followed them, and when they encountered the fork in the road, they branched out into the fork in the road to expel the creatures inside.

An Yun didn't care about himself, the snowflakes were slow, enough for them to escape. She borrowed the mines for a while, and she was the one who disturbed them in the first place.

After cleaning up, An Yun walked along the mine and searched for a while in the labyrinthine underground mine, finding a mine with a relatively wide terrain and a relatively solid cave wall.

She first laid an iron wall array on the surrounding cave walls to strengthen the strength of the walls. She then shattered the wall stone at the entrance of the cave, sealing the hole, leaving only a few vents.

In the end, An Yun laid out eight killing formations in the cave in one go, using fifteen medium-grade spirit stones as the source power of the formation. If anything happens, the formation can be touched by her mind and kill the enemy who comes to attack.

After the qiē was arranged, An Yun swallowed two Qi Nourishing Pills and meditated to restore his spiritual power.

After a stick of incense, An Yun opened his eyes, took out all the intermediate array disks and fifth-order talismans in his hand, and began to study them.

In his previous life, An Yun had such an idea, if the formation and the talisman were perfectly combined, not only could they make up for the buffer time of the formation, but the power of the two would be superimposed, and the lethality would be increased by at least ten times.

The talisman is a talisman pen that Fu Xiu draws complex patterns on the rune paper, so that a spell can be imprisoned on the rune paper. When used, you only need to pour a small amount of spiritual power into the rune paper, and the rune paper can send out a spell.

Fu Xiu is different from Dan Xiu, Array Xiu, etc., and the power of the rune drawn by Fu Xiu depends entirely on the strength of the person who draws the rune. For example, Liuyun Zhenren is a monk in the late stage of Jindan, and each of the talismans he makes has at least the power of a blow from a Jindan monk. On the contrary, no matter how high the level of the Liuyun talisman was, he would not be able to draw the eighth-order talisman of the Yuan Infant Stage.

The reason is very simple, the spell of each rune paper can only be poured into the spell by the person who drew the rune, and no one else can do it for him, so the power of the rune is directly proportional to his cultivation.

Another point is that the talisman only has the power of one blow, and after the talisman paper is shot, it is not controlled by the user.

Generally speaking, talismans are very rare and good, especially high-level talismans. Just imagine, if two cultivators are equivalent in the fighting method, one reaches out and takes out a handful of talismans from the storage bag and throws them at the other...... The results speak for themselves. Of course, few people use talismans like this, because they are too expensive.

The formation method is different, and low-level monks can also lay out high-level formations, even if the opponent's cultivation is higher than their own, and then use the formation to defeat the strong with the weak and kill the strong enemy.

The weakness of the formation is that it takes time to set up, and the opponent has time to kill the person who set it up. Therefore, formation cultivation is the most taboo for others to get close, once they get close, their formation is equivalent to breaking directly.

However, once the formation is activated, as long as the spiritual power provided by the spirit stone is sufficient and the formation center is not destroyed, the energy will continue to use the power of heaven and earth to bombard the opponent alive in the formation.

An Yun had a whim in his previous life and wanted to combine the two, there were talismans in the array, and there was a talisma in the talisman. It can not only perfectly speed up the formation and avoid the embarrassing time of the formation, but also extend the time for the talisman to be released, so that it can cycle in the formation.

In her previous life, she had studied the formation of the Formation Talisman, and she had failed only once out of a thousand attempts. However, when An Yun saw the power of the Formation Talisman of Success, he decided that no matter how to do it, he also had to study the Array Talisman thoroughly.

It's a pity that Ye Tiancheng came to her to go to the battlefield of ancient gods and demons together, and she readily agreed, but she didn't expect that she would never have the opportunity to completely confirm her thoughts in her heart.

An Yun first took out a Ten Thousand Swords Returning to the Sect Talisman, and then picked out a pair of Great Sumeru Thick Earth Array Plates and three Wuxu Youquan Water Banners. The five elements are mutually reinforcing, the earth is born of gold, and the gold is born of water, and the integration of these three is the essence of the talisman in the array.

She pinched the cloth of the Great Sumeru thick earth array with one hand, and pinched the secret cloth Wuxu Youquan water array with the other hand, and the ten thousand swords returning to the sect talisman fell in the two formations.

The earth aura of the Great Sumeru Thick Earth Formation instantly touched the Ten Thousand Swords Returning Talisman, and the sword light in the array was magnificent, and the golden light was dazzling.

Jin Shengshui, the sword qi stimulated the Wuxu Youquan Water Array, which originally took half an hour to lay out, and the slowly forming formation of the formation pattern suddenly accelerated, but all the lines were engraved in three breaths.

The cave was filled with water vapor, the ground was cracked, and there were thousands of sword lights shining in the array, and the sound of golden clashing resounded throughout the mine.

An Yun's face suddenly changed, he kicked his feet, and retreated violently into a fork in the road.

The cave shook as if it had collapsed, the earth and rocks fell one after another, and An Yun did not stop, speeding towards the fork in the road.

After a long time, the mine calmed down, and An Yun reappeared in place.

Failed. The loss was huge, wasting a fifth-order talisman and two mid-level array disks.

An Yun was not discouraged, and after cleaning up the scene, he took out a Ten Thousand Trees Towering Talisman and continued to experiment.

She must grasp the essence of the formation charm 100%, and ensure that she can use it at any time, she has to face the Jindan late stage monk, if there is a little difference, she will never have a second chance.

In this way, An Yun began to experiment day and night in the mine.

Failure, failure, failure, failure......

She has the foundation of her previous life, constantly summing up the reasons in her failures, constantly improving her methods, and pondering the essence of the formation. If she succeeded, she tried her best to understand the reason for her success, and then tried again.

It wasn't until there were only three talismans left in An Yun's hand, only three pairs of intermediate array disks left, and thirteen pairs of primary array array flags left, that she stopped the experiment.

The abandoned mine was in shambles, the nearby forked holes were cracked, and a tenth of the massive underground mine was destroyed. If it weren't for the fact that there was a divine sense ban laid by the powerful cultivators of the previous generation above the mine, and she wreaked havoc here, I am afraid that there would have been a disciple of Chaoyun Sect who would have come to investigate.

It took a huge price, and the results were gratifying, and An Yun was eighty percent sure that he could casually lay out the talisman in the formation at this moment.

An Yun showed a satisfied smile on his face, the success rate of eighty percent is not low, and it is guaranteed to surprise Liuyun Zhenren.

After looking around, An Yun thought for a while, and decided to regain his energy here and build a foundation in the cave.
