Entering the mine, Lin Quan casually summoned four armadillo lizards and asked them to clear the way in front. He followed closely behind, walking briskly towards the location of the "Heavenly Rune Stone" that he was in charge of.

With these four first-order high-level lizards here, he no longer had to worry about those ghost slaves that might appear. Taking advantage of the time to leave, he recalled the conversation he had with the old face not long ago, and his face became cloudy.

This goodbye old face is really unacceptable.

Because this so-called "Liuhe Yin Spirit Array" must be a ghost deliberately made by Xu Mingyue and Qiao Ye, but for the sake of the secret room of the Weixuan lineage, for Du Hongbo, he didn't want to give up this opportunity even if he knew it was a trap.

In order to increase his chances of winning, he didn't say much after seeing the old face, and directly asked about everything about the Liuhe Yin Spirit Array.

The old face, who was holding back his resentment, was obviously unwilling to cooperate, and refused to reply on the grounds that Lin Quan had not fulfilled a wish for him. And on the grounds that he unconditionally gave the "Holy Armor Returning to the Yuan Jue", he wanted to increase his chips in turn.

Of course, Lin Quan would not compromise, and it would be good if the old face didn't mention the Holy Armor Returning to the Yuan Technique, but when he mentioned this stubble, he was even more angry in his heart, and scolded the old face for his bad intentions, causing him to almost be affected by the sudden "resonance".

In the end, he said with an extremely tough attitude that he didn't necessarily have to understand this Liuhe Yin Spirit Array. If the old face is willing to cooperate, then he will also do more for his wishes in the future.

In the end, the old face under the eaves could only pinch his nose and answer for his wishes. And very consciously took the jade slip and looked it up.

In less than a cup of tea, the old face put down the jade slip and confidently said his conclusion.

"What, there are traces of man-made carving on the Heavenly Rune Stone, and this 'Liuhe Yin Spirit Array' is actually a composite magic array fused by two 'Three Yin Ghost Arrays', one Yin and one Yang?"

Lin Quan almost bit his tongue after listening to the old face's conclusion.

"What, do you think that this immature formation technique can still hide from the old man's eyes? Forget it, anyway, this level of second-order magic array is nothing to you with the Four Holy War Armor, as long as you pay attention not to be affected by the martyrdom. ”

The old face didn't bother to argue about this kind of issue at all, he could even easily arrange the "Four Holy Nirvana Array", a compound magic array that was also counted in the upper realm, how could he look at this kind of pediatrics. So he copied all the content about the "Two Yi and Three Yin Ghost Array" into the jade slip and closed his eyes.

After getting the jade slip, Lin Quan kept thinking about it, but the more he learned about this magic circle, the more surprised he was in his heart. If it weren't for the guidance of the old face, he would never have thought that this Three Yin Array would have so many changes and wonderful uses. Especially in the process of standing and infusing spiritual power, there is a lot of exquisiteness, and if you are not careful, you will fall into a trap.

In this way, with a feeling of jealousy, he came all the way to a strange boulder carved with lines.

Glancing at the chronometer, he tapped the spirit beast bag.

"Kitten, come out to work!"

"Squeak ......"

The little guy deftly sprang out of the mouth of the bag, quickly climbed to Lin Quan's shoulder, and then glared at his master vigorously.

It has long been accustomed to eating and sleeping in the Tai Chi space, and it is no longer suitable for staying in the narrow spirit beast bag when it wakes up to play. This time, of course, it has to blackmail its owner into a good meal.

"Alright, I know your grievances, but I'll make it up to you. ”

Lin Quan rubbed the little guy's smooth fur, teased it and gave the order.

Under the command of his master, the smart little guy jumped to the top of the Heavenly Rune Stone with a "swoop", and then carefully opened his small mouth and gnawed at a certain place.

For a moment, a series of small "clicks" sounded in the silent mine.

Fortunately, before this plan was implemented, the Xu family had already ordered the mine to be closed and no one was allowed to enter. Otherwise, he wouldn't have been so bold to summon the little guy to help.

The Two Yi and Three Yin Demon Arrays are two compound magic arrays that are independent of each other, but have a close connection.

Each group of three yin arrays can be operated separately or combined with each other. When it runs alone, it can be presided over by one or three condensate monks, but in order to exert the full power of the compound circle, at least three monks need to infuse spiritual power together.

Qiao Ye had only said that it would not seem difficult to let everyone use their own spiritual power to prevent the Heavenly Rune Stone from releasing a stick of incense, but in fact, it was a lie, and it was even more vicious.

Because according to the characteristics of the Three Yin Ghost Evil Array, it can not only gather the earth's leyline yin qi, but also transform the enveloping area of the formation into a place containing rich yin qi. In addition, it can also reverse this effect, and in turn extract the spiritual power of the monk and the surrounding air to continuously strengthen the power of the circle.

After understanding this feature, combined with the situation of the unmysterious room, Lin Quan roughly guessed their thoughts. In order not to fall victim to himself, he had to artificially alter the integrity of the circle.

Half an hour later, the chronometer in front of Lin Quan suddenly let out a clear sound.

He stood up quietly, stretched out his palm and put on the Heavenly Rune Stone that he had moved, and then a cyan spiritual power slowly poured into it.

At this moment, far away in the other five corners of the mine, Xu Mingyuan, Qiao Ye, the three elders of the young woman, and the two daughters of Lei and Yu all injected spiritual power into the heavenly rune stones in front of them.

The difference was that Lei Ruolan and Yu Lingfeng's faces were quite solemn, and they cautiously summoned a spirit pet to protect the Dharma before infusing spiritual power. As for the three elders of the Xu family, they all showed a strange smile.

With the injection of six majestic spiritual powers, the six heavenly rune stones gradually emitted bursts of black qi. After a while, a large net of black yin qi formed at an unknown depth under everyone's feet. The temperature in the entire cavern dropped again.

Lin Quan stared at every meticulous change on the Heavenly Rune Stone in front of him, silently calculating the time in his heart. Xu Mingyue and Qiao Ye in the distance were also doing the same thing, waiting for the time to come.

............

The mutation in the cavern was so obvious that all the monks standing on the surface could clearly feel it.

Some of the miners with low cultivation all retreated a distance uneasily, and they couldn't help but look in the direction where the top leaders of the Xu family were located.

Xu Mingyuan watched all this without changing his face, Qiao Ye had explained everything to him a day ago, so although he had a lot of worries in his heart, he was finally able to stabilize it.

The patriarch's calm appearance of having everything under control immediately infected everyone, and all the miners who showed uneasiness immediately took a few steps forward with a sneer, and the Xu family steward and the elite Black Eagle guards who were standing behind the patriarch straightened their chests and were honored.

Time passed little by little in everyone's expectant gaze.

Just as a stick of incense was about to arrive, the figures of three men in the dark mine stopped pouring spiritual power into the heavenly rune stone without warning, and decisively withdrew their palms, running towards a certain grotto as fast as possible.

One of the young men left four large lizards in place and asked them to inject spiritual power into the Heavenly Rune Stone instead of him, while the other big man wearing a hat took out a jade plate from his arms and quickly flicked it a few times.

Suddenly, the six Heavenly Rune Stones flashed with a strange light at the same time. In addition, a certain cave located in the center of the large array had gathered a large amount of black qi in a short period of time.

Immediately after, the faces of the remaining three women changed abruptly. One moment ago, they were still trying to infuse spiritual power into the Heavenly Rune Stone to suppress the extravasation of Yin Qi, but the next moment, an extremely strong suction force came from the Heavenly Rune Stone, recklessly devouring all the spiritual power and Yin Qi around them.

In a panic, they wanted to withdraw immediately, but they found that they couldn't get rid of the absorption of the Heavenly Rune Stone no matter what, and the spiritual power of their whole body was constantly being sucked away uncontrollably.

The young woman's face turned pale, and she kept struggling and cursing, but the result was that the consumption of spiritual power was even greater.

However, Lei and the second daughter were a little calm, only to see the gold and red light on their bodies flash, and two exquisite and abnormal armors covered their delicate bodies. Under the protection of the battle armor, the speed of spiritual power passing has obviously slowed down a lot.

More than an hour later, Xu Mingyue and Qiao Ye arrived at the cave filled with a large amount of black gas almost at the same time.

"Brother Joe, how's it going?"

"It's perfect, all four of them were taken by the magic circle, but there are three spiritual powers in it that are obviously very slow, it seems that the three of them have good things on them!" Qiao Ye raised the array disk in his hand.

"Since that's the case, let's start, I think after more than an hour of suction, the yin veins under that ancient prohibition shouldn't be able to provide much yin qi!"

Xu Mingyue's face turned grim, and he couldn't wait to say.

"What about the Third Elder, although if you detonate the magic circle now, you can break that ancient prohibition, but most of the mine will collapse, and she will definitely not be able to escape if her spiritual power is almost exhausted. ”

Qiao Ye was silent for a while, a little unbearable in his heart. "After all, she is your fourth sister, and thanks to her secret help during this time, otherwise ......"

"If Brother Qiao can't do it, Xu can do it for him. I think the fourth sister must be able to understand. Xu Mingyue smiled and said shamelessly.

“......”

Qiao Ye's cheeks twitched, and finally he decisively punched out a spiritual trick.

There was a muffled sound of "boom", and Xu Mingyuan only felt that the entire Black Mountain mine shook violently.

Before he could react, a series of violent earthquakes came from the ground, and suddenly there was a burst of people turning on their backs, many mines that went straight to the ground collapsed, and the hard ground also randomly cracked countless openings of different shades.

"Quick, the mine is about to collapse, everyone quickly get out!"

With Xu Mingyuan's loud shout, all those who could take off flew into the air one after another.

The low-level miners were scurrying off into the distance as if they were dying. I don't know how deep this black mountain mine is, and once it is buried, it is difficult for even the condensate monks to get out.

This sudden earthquake lasted for a whole day, looking at the original site of the mine, all the disciples of the Xu family, including Xu Mingyuan, were stunned.
