With so many maps drawn by the old miners in hand, Lin Quan's familiarity with the Black Mountain mine has reached a new level.

At the same time, he further confirmed the correctness of the conclusion he had just reached:

The secret room left behind by the "Unmysterious Bloodline" is really within the range of those ghost pawns that have been haunting!

Whether it was a coincidence caused by man-made or some special reason, Lin Quanzai couldn't sit still. He got up and hurried back to the mine again.

In the next few days, he no longer searched aimlessly, but directly entered the area he had speculated as fast as he could, and began to explore more carefully little by little.

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

This is a natural underground grotto with a radius of more than ten zhang.

The hedron embedded in the dome and the walls emitted a hazy glow, through which the ground could be seen littered with severed limbs, but a closer look revealed that the dull limbs were not human flesh and blood, but the remains of humanoid golems that had been dismantled.

Everything in the grotto looks very strange, but the most eye-catching thing is an ancient circle in the center of the grotto.

The circle was about the size of a square zhang, and it was carved with intricate patterns and lines, and its entire body was covered in a dark aura shield. Even people who don't know the way of the formation can tell at a glance that this magic circle full of vicissitudes is from the hands of an ancient monk.

At this time, a black-faced man wearing a hat was standing next to the circle.

He sealed his hands and controlled three strangely shaped jet-black short knives to continuously slash at the outer layer of light on the periphery of the circle, bursting into clouds of jet-black light in the muffled sound of "rumbling".

These three short knives are not only strange in style, but also quite domineering in power, and a discerning person can know at a glance that they are a complete set of spiritual weapons. It's just that no matter how hard the black-faced man tried, the short knife couldn't have a slight effect on that layer of black light.

After a while, he withdrew his short knife with a dejected expression, sighed secretly, and took out another jade plate and a jade bead, and silently circled around the Fa, stopping from time to time and fiddling with a plate and a bead, as if he was trying to calculate something.

"Well, when are we going to break this damn ban?"

At this time, a middle-aged man in an apricot yellow robe quietly appeared in a corner of the grotto, and I don't know if he had been hidden here or had suddenly entered by some means.

"Judging from the current situation, it is estimated that it will take about ten days. ”

The big man was not at all surprised by the appearance of the Taoist priest, and he continued to calculate without raising his head.

"Ten days?"

The Taoist priest was obviously extremely dissatisfied with such an answer. He paced back and forth a few steps, and complained:

"Didn't you swear that once the formation was completed, you would be able to easily get it?"

"Yes, I did. But you don't know the methods of the ancient monks, not to mention that this place was full of second-order black crystal puppets at that time, how could I judge so accurately at a glance?"

The big man in the hat stared, and his already dark face became a little gloomy.

"Speaking of which, I have already tried my best to break this ancient prohibition without harming the ancient teleportation array. Besides, without the help of the Three Yin Array that I spent three months arranging, would we have been able to deal with so many Sombra puppets so easily?"

"This ...... Well, I lost my words for my brother just now, and I ask my brother not to be surprised if he offended. The Taoist priest arched his hand with a sneer, "But we really don't have so much time!"

"What, you're worried about those three people?"

The big man with a hat looked a little soothing, "It's only been ten days now, and even if such a big mine hole is given to them for another month, they won't want to turn it around again, and we will already have it by then." ”

"You're only half right. Those two girls are indeed early, but the kid surnamed Lin is different. He had come straight to this neighborhood two days ago, and at his speed, it would take him six or seven days at most. The Taoist priest sighed.

"What? How could it be so coincidental?"

The big man in the hat was a little unconvinced. "The location where they entered the cave is so far away from here, why would he go directly across such a large area and come here to search?"

"I inquired, Lin Xiaozi secretly bought a batch of maps from some old miners three days ago, and it is estimated that it was from that time that he discovered that the ghost pawn had been guarding this area. ”

The Taoist priest was a little annoyed, "I should have listened to you if I knew this, and killed those old miners with a ruthless hand!"

"It's too late to say anything now. I only hope that his purpose is to exterminate the ghosts, not to go to this mysterious secret room. ”

"This is impossible! If we hadn't slaughtered the man surnamed Du, we wouldn't have known that there was such a big secret hidden under this ancient mine. And if I hadn't performed the Soul Search Technique, we wouldn't have been able to enter this secret room even if we found it. ”

The big man shook his head: "Forget it, no matter what he wants, we have to step up." ”

"Well, I'll speed things up as fast as I can, and you go up there and get him in some trouble, and if you can lure him away with a ghost slave, it's best. ”

"Okay, then I'll go up first. The Taoist priest nodded, and his figure disappeared into the grotto in a flash.

The big man looked at the place where the Taoist priest had disappeared, and his eyes hidden under the hat flickered, and then he continued to fiddle with the jade plate and jade beads.

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

On the fifteenth day, Lin Quan pretended to be listless and walked slowly into a small attic. At this time, Lei and Yu were already here.

This is their third time together.

Long before entering the mine, they agreed to meet every five days unless there were special circumstances. After all, the mine is too large, so it can also be better communicated.

"Brother Lin, it seems that you still haven't gained anything in the past few days. Yu Lingfeng chuckled and teased kindly.

After getting along for a period of time, she felt that Lin Quan was not a bad person, especially the fact that she gave her a Heavenly Spirit Root disciple for nothing made her have a good impression of him.

Lei Ruolan didn't speak, just nodded with a smile.

In fact, to be able to make her ice beauty smile was already a kind of affirmation for a male monk. At least in the Three Kingdoms Immortal Cultivation Realm, apart from her elders, no male monk had ever seen her smile.

"The two fairies please. ”

Lin Quan arched his hand, and naturally took a small cup and poured spiritual tea for himself, and after taking a big sip, the cow smiled bitterly: "It's true that I've been working in vain for five days, I don't know what you have discovered?"

"Hehe, although Sister Ruolan and I didn't find the ghost, we each found a strange place. Yu Lingfeng also stopped selling Guan Zi, and directly handed out two jade slips.

Lin Quan was very curious and grabbed the jade slip and sank his spiritual sense into it.

There are two strange stone patterns engraved with strange patterns. From his point of view, the lines on this stone clearly contain some kind of mystery, and it looks like some kind of formation pattern.

However, he had never seen anyone carve part of the formation pattern into two meaningless stones, and if he looked closely, these formation-like things did not seem to be made by human hands, but more like natural formations.

"It's ...... Celestial Runestone?"

After pondering for a long time, Lin Quan asked with some uncertainty.

In the past, he had indeed heard Du Hongbo talk about the rumors of the "Heavenly Rune Stone". It is said that in the world of cultivating immortals, as long as it is tangible, such as gold, wood, iron, stone, etc., it is possible to form this kind of rune-like lines on the surface after the changes of the ancient ages and some special encounters, which look like a stone with runes depicted. Generally speaking, the Heavenly Rune Stone is a kind of chicken rib thing that only has its shape and does not have its god, and it will not have any special effect at all.

"Yes, Brother Lin is really well-informed, Sister Ruolan and I thought about it for a long time. ”

Yu Lingfeng was a little surprised, she and Lei Ruolan both searched along the edge of the mine to the middle, and when they found this Heavenly Rune Stone, they all had no bottom in their hearts, so they specially entered it into the jade slip and brought it back.

"And these two Heavenly Rune Stones are not chicken ribs, they ...... It's all 'alive'. Lei Ruolan added.

"What's so special about them?"

Lin Quan's heart suddenly suddenly, and then he asked, "By the way, where did you find it in the mine?"

After speaking, he immediately took out a map and spread it on the jade case.

"The specific effect seems to be to gather yin qi, anyway, there are obviously more ghost slaves in the vicinity than in other places. ”

Lei and Yu had a clear understanding of this, which made Lin Quan feel a little at ease. Later, they pointed out the location of the two celestial runes on the map.

"Could it be that this is the reason why there are so many ghosts in the mine? Forget it, let's ignore this for now, if you want to come to the Xu family, you must have known it a long time ago. Lin Quan frowned and thought for a while, and finally decided not to meddle in his business.

In fact, it wasn't that he hadn't considered the connection between the Heavenly Rune Stone and the unmysterious room he was looking for. But thinking that it would not take a few days to determine the location of the secret room, I dispelled the idea of going to see it with my own eyes.

Lin Quan's proposal also hit the second daughter's hand, and then the three of them chatted casually for a while before ending the discussion and going back to rest.

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

After a few more days, when Lin Quan killed more than a dozen ghost slaves in a row, he came to a relatively wide cave. He glanced at it casually, and suddenly his heart suddenly rejoiced.

However, his face did not show the slightest hint of joy, and even his gaze did not stop looking away from the position he had already locked, pretending to be resting to look at the situation around him.

He didn't notice that not far behind him there was a vague figure that had been silently watching him.

After a while, when he had made sure that the place he was looking for was somewhere, he twisted his neck and walked back to another passage.

After Lin Quan left the work of a stick of incense, the figure hidden in the dark slowly came to this grotto.

I saw that he was covered with a blue light veil, and there was no trace of spiritual power fluctuations on his body. He felt it carefully, and when he was sure that there was no one nearby, he lifted the light veil.

As soon as this light veil left his body, a powerful spiritual power fluctuation that belonged to the mid-stage condensation cultivator rose instantly. and revealed a face that was almost the same as that of the Xu family patriarch, and it turned out that he was Xu Mingyue, the great elder of the Xu family.

Xu Mingyue slowly walked to the position where Lin Quan was standing before, and then kept repeating the action that Lin Quan had just done, and after a while, a cold light flashed in his eyes, and he kept muttering something to himself.
