Of course, a hundred years ago, I don't know how many bloodsheds such a mid-grade spiritual vein will cause, but now no one cares about it at all.

Moreover, he had seen a lot of similar spiritual veins Shen Xuzi, and he sighed extremely every time.

Trying to find one or two spirit stones from these spiritual veins that still contain spiritual energy is tantamount to looking for a needle in a haystack, and it all depends on luck.

Just when Shen Xuzi sighed for a long time, Fang Yunchen was thinking in his heart about how to get this waste spirit vein out.

After all, the little space of the dragon python bone ring can only be said to be a drop in the bucket.

"But this waste spirit vein is somewhat strange......"

Why is it that a spiritual vein of such a scale has never been recorded in the Anseong County Chronicles?

Hundreds of years ago, when the aura was not exhausted, why didn't any monks discover this spiritual vein?

The only plausible explanation is that someone has covered up the existence of this spiritual vein, so that for so many years, no one has discovered the spiritual vein.

Even if the four wealthy clans had occupied the Cold Valley Mine for so many years, they had not noticed the existence of the spirit vein.

"There must be a demon among them!"

So, Fang Yunchen continued to walk forward while carefully observing the direction of this waste spirit vein.

Soon, Fang Yunchen seemed to have made a new discovery, and continued to wander around the tunnel with Shen Xuzi, and not long after, he actually found a spiritual vein of the same scale, which was dozens of zhang long.

Just the waste spirit stones visible to the naked eye on the rock wall are enough to have tens of thousands.

"This ...... How can there be so many spiritual veins? ”

Shen Xuzi finally noticed the biggest strangeness in the Hangu Mine, and his face was puzzled.

Fang Yunchen continued to touch forward without saying a word, and as a result, he quickly found a third waste spirit vein.

It is comparable to the scale of the first two places, and it is also dozens of feet longitudinal and horizontal, and the number of spirit stones is staggering.

"Someone has laid a formation with spiritual veins here!"

After carefully observing it with Fang Yunchen for a while, Shen Xuzi suddenly blurted out, and his face became extremely solemn.

He cultivated the Ancient Runic Dao, and he also knew a little bit about the formation, and according to the location and direction of the three waste spirit veins that had been discovered so far, it was easy to find the truth of the matter.

Back then, I was afraid that there was a great power to use their magical powers to move these waste spirit veins here, and set up the next earth-shattering formation, covering at least the entire mine.

Fang Yunchen on the side nodded after hearing this, and echoed: "What the Dao Chief said is extremely true, and this official guesses that there should be a fourth spiritual vein here, and the four veins are one, forming the momentum of the four dragons guarding the coffin......"

"Four Dragons Guarding the Pavilion?"

Shen Xuzi's face sank, but he heard Fang Yunchen continue: "Back then, I am afraid that this was the suppression of a terrifying existence with great strength, otherwise there would be no need for such a big deal. ”

"That's right, that's true of the Eight Achievements."

Shen Xuzi nodded, indicating that what Fang Yunchen said coincided with his guess, and he said worriedly: "Now that the aura is getting thinner and thinner, the formation of the four dragons guarding the coffin has lost its power, if that demon suddenly breaks the ban, wouldn't the entire Ancheng be very dangerous?" ”

"Fortunately, the demon who was suppressed here after the spiritual energy was depleted seems to have fallen into a deep sleep, but I don't know when it will wake up. But fortunately, it was discovered in time, so I asked the official to reactivate the big array and seal this demon again. He also asked the Taoist chief to go to the entrance of the cave to suppress the formation for the official, and at the same time told Ge Minghui that they would leave first with the people, so as not to affect these defenseless people in case something happened. ”

After thinking about it for a while, Fang Yunchen put on a very professional and confident posture, saying that it was actually to let Shen Xuzi retreat first, and he could leave it to him alone.

"This ......"

Originally, Shen Xuzi planned to ask, "My lord, can you do it alone", but seeing that Fang Yunchen was so confident, he didn't take this risk.

If you make the boss angry and your salary is deducted, it will be a big loss.

"Okay, Poor Dao is going to pass the word, you have to be more careful, my lord......"

After saying that, Shen Xuzi left in a hurry, he remembered that when he came, the road was full of blood pattern stones the size of a basin, and now there was just no one to supervise, so he took two pieces and took them back to study, wouldn't it be beautiful?

"Alright, let's go!"

And after Fang Yunchen left, he immediately started the long-planned transportation business.

In addition to the complete waste spirit stones on the rock wall, there were also a large number of spirit stone fragments scattered on the ground, which were basically medium-grade spirit stones, and only a very few were low-grade spirit stones.

After the restoration, the medium-grade spirit stones are worth at least ten low-grade spirit stones.

The key is that the aura in the medium-grade spirit stone is more refined, and the difficulty of refining is lower.

Therefore, for a monk with a normal mind, let alone ten pieces, even if he gives twelve or fifteen lower-grade spirit stones, he may not be willing to exchange a medium-grade spirit stone.

And such medium-grade spirit stones can be seen everywhere in this tunnel, as many as stars in the sky.

This time it was Fang Yunchen's turn to tremble with excitement.

What else is there to say about this, all of them are included in the dragon python bone ring, and they will slowly recover after they have spare strength in the future, so as to realize the true freedom of the spirit stone.

Of course, compared to the spirit stones in the rock wall, the spirit stone fragments that Fang Yunchen moved away could only be regarded as a drop in the bucket.

The spirit stones scattered on the ground are just waste spirit stones that have fallen from the surface of the rock wall under the erosion of time.

And Fang Yunchen investigated carefully, and he found that these spirit veins that had been refined into a large array were very powerful, and the deeper part of the rock wall was almost all high-grade spirit stones, only mixed with a few medium-grade spirit stones.

Therefore, for the waste spirit stone on the rock wall, Fang Yunchen did not dare to act rashly.

After all, looking at the battle of these spiritual veins, you know that the demon who is sealed here must be extraordinary.

If this guy succeeds in breaking through the big array and rushing out, Ancheng will definitely be the first to suffer.

After picking up all the spirit stone fragments in the known area, Fang Yunchen also had a general understanding of the formation here.

Looking at his remaining merit points, Fang Yunchen couldn't help but sigh secretly, I'm afraid I'm going to have to bleed today.

After all, what he had to do next was to try to restore the entire Great Array.

No matter how powerful the devil is, he still can't compete with this expensive array, and he hasn't been lying obediently in the depths of the mine for so many years, and he can't even make a sound.

What's more, even if the aura is exhausted now, the demon still can't break through the seal, which shows that this big array has withstood the test of time and is absolutely reliable.

But in order to fully activate this large array, it is necessary to restore these four veins that have been depleted for many years.

Even if Fang Yunchen was squeezed dry, his merit value would only restore the tip of the iceberg of one of the veins.

Therefore, Fang Yunchen planned to directly find the eye of this great array and see if he could restore it first.

"Four Dragons Guarding the Coffin...... The eye of the array must be at the intersection of the four dragons! ”

However, when he came to the expected meeting place, he found that the tunnel was empty, and there was nothing to use as an eye.
