In fact, Ye Fei didn't know what kind of spirit stone it was, but he could sense a very strong spiritual power from this spirit stone, and this kind of spiritual power was one he had never seen before.

But when he saw the Netherworld King's expression that was even more exaggerated than him, and even heard him say what kind of ancient spirit stone it was, this made Ye Fei even more puzzled, and looked at the Netherworld King and said, "What is the Ancient Spirit Stone?"

Hearing Ye Fei ask him, the Netherworld King came back to his senses, withdrew his divine sense, and said, "You don't even know the Ancient Spirit Stone?"

Ye Fei said: "I've seen it in ancient books before, but it hasn't been introduced in too much detail, so it's not very clear, it seems that it should be a kind of spirit stone in ancient times, right?"

Seeing Ye Fei say this, the Nether King nodded: "Well, it is indeed a spirit stone in the ancient period, but it is not only a representative year, but also a grade of a spirit stone, just like the spirit stone we currently use, what is the lower grade, the middle grade, the upper grade and the best, and the ancient spirit stone is the one that is more superior to the best spirit stone." ”

"So that's the case, in this way, the spiritual power of this ancient spirit stone is very rich, and it is also a very rare one?" After Ye Fei heard this, he directly understood what was going on, to put it bluntly, this thing was just a rarer spirit stone.

"That's right, but I didn't expect that there would be ancient spirit stones here, and there don't seem to be a lot of them!" said the Nether King with an excited face.

After Ye Fei figured it out, he was also very excited, because he knew that if he had these spirit stones, he would probably be able to teleport his disciples over.

So he had to personally take out those ancient spirit stones, and let Boss Cai order those staff to withdraw first, and then let the staff come over to clean up after he got this side open.

After Boss Cai responded, he hurriedly ordered the staff to drive the equipment away, and then evacuated the other people on the scene, and the only ones left were Ye Fei's disciples and Boss Cai's own brothers.

"Senior Ye, everyone else has left. "Boss Cai knew that Ye Fei was going to do it himself.

Ye Fei nodded, and then he sacrificed the nameless sword, and rushed towards the mountain of the entire ore vein, one after another huge sword qi hit the mountain range, and the entire mountain range slowly collapsed, this is naturally Ye Fei controlled the strength, otherwise he could destroy this mountain with one easy move.

Seeing that Ye Fei blasted away the mountain, the Netherworld King also flew over excitedly, and worked with Ye Fei to take out the ancient spirit stones inside, and the other spirit stones, even several top-grade spirit stones, they didn't care.

"What a strong spiritual power!" said the Nether King.

Ye Fei also nodded excitedly: "Yes, this is not comparable to the best spirit stone at all." ”

"That's nature, let's compare it with your kid, the same piece of ancient spirit stone is at least five hundred times the spiritual power of the best spirit stone, do you say the best spirit stone can be compared?"

Ye Fei also gasped after hearing this, there were five hundred times more spiritual power than the best spirit stone, this thing was indeed precious enough, and what they had obtained so far was a full eight pieces, the largest two pieces were actually the size of a car tire, and the smallest one was also the size of a head.

Ye Fei asked, "You said this, can you teleport the disciples to the Immortal Cultivation Realm?"

"You kid want to use these to support the teleportation array......? Tyrannical creatures!" When the Nether King heard this, his eyes widened suddenly, and he looked distressed.

Ye Fei said solemnly: "That's for sure, no matter how strong its spiritual power is, it can only be used for us to cultivate at most, but wouldn't it be more useful to let them teleport disciples over?"

Seeing Ye Fei say this, the Netherworld King had to shrug his shoulders: "Come on, you kid is right, the main purpose of your coming back this time is indeed for the disciples, but don't underestimate these ancient spirit stones, they are not only rich in spiritual power, but also release spiritual power for a longer time, take these two largest pieces, you should be able to teleport thousands of people to the immortal cultivation realm, and there should be more." ”

"How many of these two pieces are the biggest?" Ye Fei's eyes widened even more when he saw the Nether King say this, and he was still wondering if he could use them all.

The Netherworld King nodded and said, "That's right, this is the benefit of the Ancient Spirit Stone, the spiritual power is rich, and the release time is longer, these two pieces are enough." ”

"I see, that's okay, there are still six pieces left, I'll give you three, those who see it have a share!" Ye Fei is also very generous, in his opinion, no matter how good things are, they are just things outside the body, and he regards the Netherworld King as a friend, so he is not stingy.

The Nether King was stunned for a long time after hearing this, and then said, "You kid will give me three pieces......?" I'm sorry. ”

"Hehe, what's so embarrassing? In that case, then you can take the three smallest pieces, and I'll put away the big ones. Ye Fei smiled, completely unceremoniously left only three small pieces for the Netherworld, and put the others away.

The corners of the Nether King's mouth twitched: "You kid clean me, okay, since that's the case, you're welcome, looking at this thing really makes me greedy, with these, it's not difficult for me to recover to the Tribulation Period." ”

"Well, then I wish you a speedy recovery to the Tribulation Period!" Ye Fei knew that the Netherworld King had been a powerhouse in the Tribulation Period before, so as long as he had enough preparations, it wouldn't take long to think about it, and he would be able to rush to the Tribulation Period.

Then, the Netherworld King put away the three ancient spirit stones, looked at this place again, and wondered: "But it's really strange, the ancient spirit stones, it is generally impossible to appear in this kind of broken land, but there are ancient spirit stones here, could it be that this is an intact place of spirit stones in the ancient period?"

Hearing the Netherworld King say this, Ye Fei was also puzzled, as soon as he thought about it, he finally felt that something was wrong, before, they had dug a lot of spirit stones here, and in other places, they had never dug up.

Then today there is an ancient spirit stone here again, in this way, I am afraid that this place is really different from other places, and then, Ye Fei looked towards the Netherworld King, and it happened that the Netherworld King also looked towards Ye Fei.

And the Netherworld King took the lead and said, "Ye Fei, you say...... Could this really be the spirit mine of the ancient period?"

"Well, I guessed too, in this way, this place is not simple, let's use our divine sense to explore. Ye Fei saw that the Netherworld's guess was exactly the same as his own, so he suggested.

The Nether King nodded and said, "Okay, let's explore each side, be careful!"

Ye Fei also nodded, and then flew forward, and began to probe near him, using his divine sense, and the Netherworld King was the same, using his divine sense to probe.

This made everyone else stunned, and Boss Cai even asked the third elder, "Elder, what are they doing Senior Ye?"

The third elder understood a little, and he said: "Sect Master, they seem to have a very rare spirit stone, maybe they think that this place is a little strange, so they are using their divine sense to detect it, I don't know the specifics, and I will know it when the sect master they finish detecting." ”

Boss Cai understood half of it, but he didn't ask anything more, just looked at the two of them curiously.

Ye Fei and the Netherworld King probed very carefully, without revealing a single place, and after half an hour, the Netherworld King shouted at Ye Fei: "Ye Fei, come over quickly." ”

Ye Fei hurriedly flew over and wondered, "What's wrong?"

"You use your Divine Sense to explore here!" said the Nether King, pointing ahead of him.

Ye Fei curiously probed his divine sense to this piece of land, and after a while, he sighed lightly and said, "There seems to be an aura down here." ”

"Well, there is, and it's very rich, if I'm not mistaken, it's the spiritual veins below. The Nether said.

"Spirit vein, do you mean that this is the lifeblood of the entire aura of the earth plane?" Ye Fei suddenly thought of something.

The Nether King nodded: "Yes, this is definitely the spiritual energy lifeline of the entire earth plane, and it controls the spiritual energy of the entire earth plane. ”

"If this is the case, I really didn't expect that the spiritual veins of the earth plane would actually be here, it seems that this place in Myanmar is actually still the place of the spiritual veins of the earth plane. Ye Fei immediately understood.

And the land of spiritual veins is like the dragon vein of a country, and the national dragon vein has the saying that it holds the lifeblood of a country, so this place of spiritual veins is also equivalent to the spiritual energy lifeline of the entire earth plane, and it holds all the spiritual energy.

The Nether King said: "It seems that the aura of the entire earth plane has become thinner, which has something to do with this place of spiritual veins, and the aura in this spiritual vein does not seem to be very rich, that is to say, this spiritual vein has been hit very hard, which makes the aura of the entire earth plane become so thin, and there is almost no spiritual energy." ”
