"It's a soul crystal! No wonder it can make people's strength increase by leaps and bounds!" Seeing that more than a thousand strong people began to cultivate with the spar they obtained, the ghost king finally recognized the origin of the spar.

What is a soul crystal? Everyone was confused.

"The soul crystal is actually the soul crystallization of a cultivator. "The Dark Dragon Lord, who is almost from the same era as the Ghost King, explains it to everyone," You don't know what a soul crystal is, in fact, it can be understood, after all, the refining method of soul crystal has been lost for many years, but if I put it another way, you may understand that we cultivators, in fact, what we are cultivating are two aspects, one is our own cultivation, and the other is our soul, these two aspects are actually complementary to each other, only when the two aspects are improved at the same time, will our cultivation be taken to the next level, and this soul crystal is actually a crystal formed by fusing the soul of a strong person with cultivation, Formed by melting their souls and cultivation, however, later, after some evil forces discovered the effect of soul crystals, they began to directly do it to some strong people, directly refining them into soul crystals, and used them to serve themselves, and it was precisely because of the crazy practices of these people that countless strong people panicked, so those strong people united and carried out a major purge of the forces on the mainland that had mastered the method of refining soul crystals, and after about a hundred years of war, those sects that mastered the method of refining soul crystals were finally completely wiped out, and the method of refining soul crystals disappeared in the torrent of history at that time。 ”

After listening to the introduction of the Dark Dragon Lord, Ling Aotian frowned, from the other party's introduction, he could naturally feel the evil of the method of refining soul crystals, and it was precisely because of this that he couldn't help but start worrying, if the Killing Alliance mastered the method of refining soul crystals, the consequences would be serious.

Seeing Ling Aotian's frowning appearance, the Ghost King naturally understood what Ling Aotian was worried about, and said: "Aotian, don't worry too much, the method of refining soul crystals has completely disappeared more than 10,000 years ago, and no one will ever grasp it, as for this batch of soul crystals of the Extermination Alliance, if I guess correctly, it should be that some of the soul crystals in that battle were not destroyed, so it was handed down." ”

"That's right, if the Extermination Alliance has mastered the method of refining soul crystals, it will definitely be impossible, after all, even if the Extermination Alliance has a method of refining soul crystals, it is impossible for them to have so many strong people to refine soul crystals, because the number of powerhouses in the middle stage of the saint level on the continent is not many, how can they be willing to use it for refining. "The Dark Dragon Lord affirmed the Ghost King's statement.

After listening to the words of the two of them, Ling Aotian finally breathed a sigh of relief, however, he was still a little worried, if the Extermination Alliance had a large number of soul crystals in his hands, the situation would obviously be extremely bad, if the other party directly created tens of thousands of Saint-level mid-stage powerhouses, then, how many people on the mainland could withstand their attacks?

Ling Aotian voiced his concerns.

Hearing Ling Aotian's concern, the Dark Dragon Lord and the Ghost King laughed loudly, and after a long time, the Ghost King stopped and said, " Then it is even more impossible, if the Extermination Alliance really has a large number of soul crystals, it is impossible for them to limit the number of people when recruiting strong people, the reason why they will take half a year is actually that the number of soul crystals in their hands is limited, if I expected it correctly, the number of soul crystals in their hands will definitely not exceed two thousand, and this time the soul crystals they used are very likely to be recovered from those strong people who died on the battlefield in the Eastern Continent. ”

"Senior, is there any way to destroy these soul crystals?" Knowing that the number of soul crystals in the Extermination Alliance would not be too much, Ling Aotian breathed a sigh of relief and began to play with the idea of this batch of soul crystals, if he could successfully destroy this batch of soul crystals, the Extermination Alliance would not be able to make any big waves.

"It's not hard to destroy these soul crystals, but I don't think it's the best time for us to do it. The Ghost King objected.

Ling Aotian was stunned for a moment, and there was a thoughtful look in his eyes.

"I think that this batch of soul crystals is obviously not owned by the Extermination Alliance, if they really have soul crystals, they may have already dominated the entire continent, obviously, they got these soul crystals, it is related to that mysterious person, if we destroy this batch of soul crystals now, I am afraid that it will startle the snake and attract the attention of that mysterious person. The Ghost King said.

Ling Aotian thought for a moment, nodded, and said, "The predecessor is right, the root cause of the war on the mainland should be on that mysterious person, and only by eliminating him can we truly restore peace to the mainland." ”

"Aotian. Do you think the old man who left earlier has any connection with that mysterious person?" Feng Qingyi said his opinion.

Yes, everyone's eyes lit up, they were worried that they couldn't find the mysterious person, maybe the old man who took out the crystal had some kind of connection with the mysterious person.

"Unfortunately, now that the old man is gone, it won't be so easy for us to find him again. Ling Aotian sighed.

Hearing Ling Aotian's slightly regretful words, a smile appeared on Feng Qingyi's face: "If we want to catch up with that old man, we have to hurry." ”

Hearing Feng Qingyi say this, Ling Aotian realized that the nine-tailed marten that had been staying on Feng Qingyi's shoulder had disappeared.

"Then what are you waiting for, let's go!" Ling Aotian said to everyone, and with the little connection between him and the Nine-Tailed Mink, he chased after him in the direction where the Nine-Tailed Mink had left.

Although the strength of the nine-tailed marten is not strong, its tracking skills are not weak, and after Feng Qingyi told it to track the old man, it has been quietly following the old man to an extremely ordinary-looking house in Eddicas City.

"Little mink, where are you chasing?" The first thing Ling Aotian did when he arrived was to ask the nine-tailed mink about the whereabouts of the old man.

"Well, the old ghost has never come out of this house again. The nine-tailed marten shook its nine fiery tails and said.

Everyone looked at the extremely ordinary-looking house, and their eyes all showed doubts, with the identity of the old man, this house obviously would not be his residence.

"Aotian, do you want to go in and have a look?" Feng Qingyi asked.

Ling Aotian thought for a moment, shook his head and said, "It's not convenient for us to go in directly like this, so let's take a look at the situation near the house for the time being, and I'll use the body of consciousness to go in and find out." ”

With everyone's cultivation, it is not difficult to use spiritual power to explore this private house, however, there is a flaw in the detection of spiritual power, if the mental power perception of the detected object is extremely keen, it is easy to detect, and it is precisely because of this that Feng Qingyi will propose to enter the private house to find out, however, Ling Aotian is obviously worried that directly entering the private house will attract the attention of the people in the house, so he denied Feng Qingyi's proposal.

The body of consciousness mentioned by Ling Aotian is actually a kind of spiritual power, however, unlike the large-scale scanning of spiritual power, after condensing into the body of consciousness, if you want to explore the situation, you can directly use the body of consciousness to inspect it, and it will not be detected like a scan of spiritual power, condensing your spiritual power into a body of consciousness, which requires extremely high spiritual power from cultivators, and Ling Aotian was barely able to do it after the dream nerve broke through to the holy level.

Seeing that Ling Aotian had a more secure method, Feng Qingyi naturally would not object, and directly nodded and agreed.

After inspecting the house and making sure that the old man would not leave from other places, they chose a few places to lurk and observe the situation of the house.

Seeing that everyone was ready, Ling Aotian began to activate his dream nerves, condensing a body of consciousness similar to his body.

After nodding to everyone, Ling Aotian's consciousness body walked towards the house.

With the miraculous effect of the body of consciousness that could not be seen with the naked eye, Ling Aotian entered the private house without any hindrance, and when he saw the situation of the private house clearly, his face became solemn.

In the house, there were two people, one was the old man who was tracked by the nine-tailed mink before, and the other was a mysterious person who couldn't see his face clearly at all, it was the mysterious person who made Ling Aotian's face solemn, just when his consciousness body had just stepped into the room, he felt that his consciousness body was locked, and the mysterious man's gaze that seemed to be able to see through everything also happened to look at the place where his consciousness body was.

It's been discovered!

The mysterious man's next words confirmed Ling Aotian's guess: "Since you're here, let's show up and see it!"

Knowing that his whereabouts had been discovered, Ling Aotian no longer hid his figure, a burst of light flashed, and his body of consciousness appeared in front of the two of them generously.

"The master is really clever, and someone is really eyeing me!" The old man's gaze as he looked at Ling Aotian's conscious body was full of murderous intent.

"I'm curious, how did you find me?" Ling Aotian completely ignored the old man with murderous intent in his eyes, and set his eyes on the mysterious man.

"The body of consciousness is indeed an excellent ability to find out the news, but it also has its own shortcomings, when you move, the mental fluctuations in the air will change, and it just so happens that I am extremely sensitive to the mental fluctuations in the air. The mysterious man calmly stated the reason.

A hint of surprise flashed in Ling Aotian's eyes.

"Young man, I wonder what you mean by tracking down my servant, I have a grudge against you?" asked the mysterious man.
