When the last array flag in the hands of the black-clothed old man fell, his hands quickly formed seals, shooting out several spiritual power marks, and submerged into the ground around him.

Suddenly, a faint layer of spiritual power rose from all around, enveloping the col that was only forty or fifty zhang in size.

"Hidden!"

With a soft snort, the gesture of the old man in black changed, and the surrounding layer of spiritual power light gradually disappeared into the air.

After arranging the formation, the figure of the old man in black flickered, and he came to the side of the blue-robed young man again.

"Master, is there really a medium-sized spiritual vein here? ”

Sensing the thin aura around him, the blue-robed young man said again with a look of lack of confidence.

"Hmph, what do you know, according to the information left by the vein seeker, the reason why this spiritual vein has not been discovered is because it goes deep into the ground, and the entire spiritual vein is shrouded by a strange stone layer that can isolate the divine sense, not only the spiritual energy of the spiritual vein cannot be leaked out, but even the spiritual consciousness of the spiritual master cannot penetrate it. ”

"If it weren't for the fact that this pulse seeker was testing this small spiritual vein in this mountain range back then, and happened to be at the end of this small spiritual vein, that is, here, a large pulse probing array was arranged, and he was unexpectedly aware of it, I'm afraid we wouldn't be here today. ”

"It's a pity that the spirit vein master, although he has made some discoveries, he has not had time to be sure. But because he met the enemy, he was seriously injured and died. I also happened to get his relics, and I was just bored to flip through them, but I didn't expect that there would be a record of this spiritual vein in it. ”

Speaking of which, even the old man in black could not hide the agitation in his heart at this moment. For him, a whole medium-sized spiritual vein, that is definitely a great fortune, and the spirit stones contained in it alone are enough for him to not worry about cultivation resources for the rest of his life. What's more, when all medium-sized spiritual veins will be accompanied by rare occurrences, this is also the goal of the old man in black.

Although I don't know what it is, according to historical records, almost all the spiritual things associated with the spiritual veins can play a great role in cultivation, which is absolutely irresistible to the attraction of the old man in black. You must know that his current cultivation has not made any progress for thousands of years, and he can only go further by relying on external objects

"But Master, just the two of us, even if there is really a medium-sized spiritual vein here, we can't move it away, and after a long time, it is very likely that someone will find it. ”

"Hmph, it's not all you stupid, it's because of such worries that I let you fight for the spiritual land, but you were defeated. If you can capture the spiritual land, coupled with the extreme remoteness of this place, we will dig slowly here, and there is no need to worry about anyone finding out. However, now, we only have to take one step at a time, first of all, we have to confirm whether there is really a spiritual vein here, and then if there is really a spiritual vein, then before others find out, how much benefit can be made, then try to get a little more. ”

Faced with the number of black-clothed old men, the blue-robed young man didn't dare to refute at all, but he seemed to remember something, and still whispered:

"That kid surnamed Yan, since he has entered the refining pool to cultivate, then it will be possible for him to return to this place in two months at the shortest and one year at the most, so we still have plenty of time. ”

"Sufficient? That's just your idea, it depends on what kind of structure this spiritual vein is, if it's the kind of spiritual stone vein without a cave, I'm afraid we won't be able to dig much in two months." But if the entire spiritual vein runs through the cave, then it will undoubtedly be an opportunity for us. ”

As soon as the words fell, the old man in black no longer paid attention to the blue-robed youth, and with a flip of his wrist, a dark green strange array disk appeared in his palm.

This array disk, in the shape of a square, is covered with some strange runes, and in the center of the front, there is a slender silver needle horizontally.

"What is this? It's like a array, but it's not like it. ”

Looking at the strange thing that appeared in the hands of the old man in black, the blue-robed young man was stunned for a moment, and couldn't help but ask curiously.

"This is a pulse-seeking device left behind by the Pulse Finder, and you can use it as a formation plate. The main thing is that through it, we can find the direction of the spiritual vein. Since the vein seeker had set up a vein seeker array back then, there should be a cave in addition, but this cave should have been blocked by the spirit vein master. ”

After speaking, the spiritual power in the body of the black-clothed old man suddenly injected into the array disk in his hand, and in an instant, the array disk emitted a strange energy fluctuation, and the silver needle on its front suddenly rotated rapidly on the surface of the array disk, and after a few turns, it gradually stopped, and the tip of the needle continued to swing slightly, pointing in one of the directions.

"Let's go!"

Seeing this situation, the old man in black had a happy face, greeted the blue-robed young man, and his body fell violently, appearing on the ground, and then, following the direction pointed by the tip of the silver needle, he walked to the left.

After a while, his footsteps stopped, and he stared intently at a dirt slope in front of him, which was about five or six zhang high, and the soil was yellow, and the surface was even more uneven.

After observing for a moment, the old man in black suddenly snorted coldly and whispered:

"The way of the Spirit Vein Master's formation is really a little different, just a blind method, but there is no energy fluctuation at all, and he almost concealed it. ”

As soon as the words fell, the spiritual power in his body surged, and he stretched out his arm and slapped it with a palm.

Suddenly, a huge palm print, condensed out of thin air, slammed towards the dirt slope not far in front of it.

"Bang!"

A roaring sound came out, and I saw a layer of white light suddenly appear on the surface of the dirt slope, and then the white light distorted and collapsed, and a pitch-black hole appeared in the eyes of the old man in black.

"There really are caves!"

The appearance of the cave couldn't help but exclaim in surprise.

Ignoring the exclamation of the blue-robed young man, the old man in black stared at the cave intently, as if sensing the situation inside, and after a while, he walked towards the cave.

Seeing this scene, the blue-robed young man did not dare to slack off, and immediately followed.

The cave was extremely deep, and the further they went, the blue-robed young man felt that they were leaning deeper into the ground, and it was about a quarter of an hour before the two stopped.

It was a dug out hall, and the walls were inscribed with some simple formations to solidify the walls in case the hall collapsed. On the ground, there is a huge formation, this formation is extremely strange, even the old man in black and the young man in blue who have studied the formation method can't see what kind of prohibition this is.

Looking at the formation on the ground that seemed to have lost its power, the old man in black couldn't help but have a thoughtful look on his face.
