But as they continued to go deeper, the black fog in the air became more and more demonic, and the black fog pillars deep underground were still gushing, and the concentration of black fog was increasing.

The demonic power gradually affected them, and when the two of them rushed to the first area, the expression on their faces was not calm, and the flow of Yuan Force in their bodies was much more sluggish.

"Big brother, you can't go any further, the black fog at this moment is still gushing out, and there is a danger in the depths. Yuankong Chengzhan fell behind Yuankong Chengtian and shouted loudly.

"No, the magic crystal is about whether I can enter the Dao Pattern Stage, no matter how dangerous it is, I have to go in and take a look. Yuan Kong Cheng Zhan didn't look back, and rushed straight towards the source of the black fog.

Yuankong Chengzhan was helpless, so he could only follow him, heading towards the deepest part of the basin, the two of them were extremely fast, and after a while, they came to the source of the black fog.

The sky-like pillar of black mist still erupted from the depths of the earth, and as soon as the two of them got closer, they felt the intensity of the demonic nature, even if they had the Yuan Force to protect the body, the soul still vibrated incessantly, the headache was splitting, and the senses of the body were also tormented by various illusions.

Yuan Kong Chengtian came to the black mist qi pillar, but he couldn't take a step forward, he was very unwilling, raised his head, the yuan power in his body flowed between his eyes, and looked above the qi pillar.

Through the layers of thick black mist, I saw that at the very top of the black mist, seven ink-black crystals of different sizes floated quietly in it, and the black fog gathered three inches away from the seven ink-black crystals, but it was impossible to get close to these seven crystals, leaving a small vacuum around the crystals.

"What?

Yuankong Chengtian suddenly lost his voice and exclaimed, when he was young, he had ventured into the edge of the source of the black fog, and he was fortunate to see the scene of the magic crystal jumping to the earth, but the magic crystal of that day was a whole piece, but at this time, it was turned into seven fragments.

"Who is it? who has been here!" Yuan Kong Chengtian roared angrily, and the blazing fire-colored clouds swirled out from his body, and the extreme heat evaporated the black mist around him, and his thick long hair flew without wind, like a desolate fire god who came from ancient times.

The magic crystal is hidden deep underground, in the black fog solid soil, there is no external force, it is impossible to shatter inexplicably, and at this time, not only the magic crystal has already been shattered, but the seven fragments at the top of the black fog are also obviously incomplete, and the difference between the magic crystal in Yuankong Chengtian's impression is huge, at least one-third less.

"The magic crystal is broken, how is this possible?" Yuan Kong Chengzhan was also extremely shocked, he tried to look at the top of the black mist, but he couldn't see clearly.

"Shu Wei! it must be Shu Wei, Yuntai City, only he can go deep into the underground source and seize the magic crystal!" Yuan Kong Chengtian's eyes were red, his body trembled, and he could barely control himself.

"Okay, okay, do you want to prevent me from achieving the Dao Pattern, shattering the Demon Crystal, making it incomplete, thinking that you can make it impossible for me to refine the Martial Dao on the edge of the Demon Crystal?"

Yuankong Chengtian suddenly roared angrily, he turned to look at Yuankong Chengzhan and said solemnly: "Old Seven, in the future, the Hunter King and the Yuankong Marquis Mansion will be handed over to you, remember, the industry of the Yuankong Marquis Mansion is not important, only the Hunter King and the Yuankong clan are the foundation of my Yuankong Marquis Mansion." ”

"Big brother, what are you going to do, you can't be impulsive!" Yuankong Chengzhan seemed to realize Yuankong Chengtian's intentions, and hurriedly stopped.

"Since the magic crystal is shattered and the power is greatly reduced, it will have no effect if I receive the magic crystal tempering at the edge, in that case, then why don't I enter there!" Yuankong Chengtian's arm pointed to the top of the black mist, with a crazy look on his face.

"Big brother, don't be impulsive, even if the power of the magic crystal is greatly lost, it is not something that we and other martial artists in the mansion building period can touch, my father once said that if you don't reach the Dao Pattern period, you must not fight this magic crystal. "Yuankong is in a hurry.

"But don't you want to know where my father went?"

Yuankong Chengzhan said with a solemn face: "Although outsiders think that the growth of the Yuankong Marquis Mansion in recent years is because of me, but only you and I know that this is all the credit of my father, he achieved the Dao pattern at the age of thirty, and it is even more possible to go further in this life, but because of a mysterious call, he panicked and disappeared mysteriously, don't you want to know the reason!"

"This ......"

Yuan Kong Chengzhan was speechless for a while, he slowed down, and said, "But my father once told us never to touch that secret. ”

"But that's really what you think in your heart?" asked Yuankong Chengtian rhetorically.

"I, I'm really unwilling. Yuan Kong Chengzhan was silent for a long time and said in a low voice.

"So I have to take a risk, and since Shu Wei has already made a move, if I can't break through the Dao pattern, the Yuankong Clan will be wiped out, just in the near future!"

Yuan Kong Chengzhan was surrounded by fire, his body jumped, burst into the air, and rushed towards the pillar of black mist that rose into the sky, and disappeared in the blink of an eye.

"Big brother!"

Yuan Kong Chengzhan's eyes were rarely slightly moist, he glanced at the black air column that was steaming and rising into the sky, sighed, resolutely turned around, and galloped towards the periphery of the basin, the speed was faster than when he came, and a few breaths disappeared.

The black mist pillar was still gushing, the momentum was terrifying, and the rumbling sound was endless, and after a while, an extremely shocking and vague sound suddenly came out from the rumbling black mist column.

"How can there be blood stains on the magic crystal, no, what is this? The power of the divine nature, is it the blood of the gods, how is this possible. ”

"The descendants of God only exist in legends, how can they still exist in the world......"

"Heaven and Earth Tribulation, the Fall of the Protoss......"

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

Three hours later, in the hunting camp, in an ordinary tent, Shi Long and Ye Qing sat on the animal skin blanket, silent, with a faint look of anxiety between their eyebrows.

After a while, Shi Long suddenly stood up and said, "No, Chu Yun didn't appear until this time, something must have happened in the basin, I have to go in." ”

"Shi Long, wait a little longer, Brother Chu is profound in martial arts and resourceful, there shouldn't be anything wrong, if he comes back and finds that you are not there, he will definitely enter the Hessian Cliff to look for you again." Hearing this, Ye Qing pondered for a moment and said slowly.

"But at this time, almost half a day has passed since the black mist erupted, and according to Chu Yun's travel speed, he should be able to reach the camp from the black mist at this time. ”

Shi Long was a little anxious, frowned, and said: "Since the eruption of the black mist qi column in the center of the basin, the black mist in the entire basin has become dozens of times thicker, even the martial artists of the Martial Dao Ten Levels dare not approach, Chu Yun must also be difficult to deal with, it is really difficult for me to sit here with peace of mind." ”

"Yes. Ye Qing nodded, he paused slightly, and said: "That's it, Shi Long, you wait for Chu Yun here, my body is better than yours, I will go down to the Hessen Cliff to find Brother Chu." ”

"No, let's go, my cultivation realm is deeper than yours, at this time, the black mist in the basin is violent, and the body method has no effect at all!" Shi Long stopped.

"But......" Ye Qing immediately shook his head when he heard this, he was about to say something, but he was suddenly interrupted by an extremely familiar voice from outside the tent.

"You don't have to go, I'm back. ”

The curtain of the tent opened, and a handsome young man in black armor walked in from outside the tent with a smile.

"Chu Yun!" Shi Long and Ye Qing said with joy in unison.

"Are you so unconfident in me?" Chu Yun walked into the tent, sat down on the animal skin blanket a little tiredly, and laughed.

"Chu Yun, why did you come out of the basin so late, at this time, the concentration of black fog in the basin has reached an extremely terrifying level. Shi Long said.

"Let's see what it is. Chu Yun smiled slightly, did not answer, but carefully took out a small porcelain bottle from He Huai, and poured out a transparent crystal with a black body from it.

"Hey, what is this? ”

Shi Long was a little curious, stepped forward, and grabbed the ink-black crystal that Chu Yun had poured on the animal skin blanket, but the next moment, Shi Long suddenly shuddered, and then immediately screamed, and threw out the ink-black crystal in his hand, but he retreated again and again, and his face was extremely ugly.

"This, what is this, why do I feel the demonic power of the black mist in it!" Shi Long relieved his mind before he palpitated.

"The demonic power of the black mist?" Ye Qing was a little surprised by Shi Long's strange performance when he heard this, and bent down to pick up the ink black crystal that Shi Long threw aside, but then, his expression also changed violently, and he threw the ink black crystal into his palm with a shake of his arm, panting heavily.

"That's because of this thing. Chu Yun said.

"Chu Yun, what the hell is this?" Ye Qing looked at the inky black crystals lying quietly on the ground, and there was still a little fear in his expression.

"This thing is the source of the black mist gushing in the basin!" Chu Yun said.

"The source of the black mist?" Shi Long frowned slightly, and then suddenly woke up: "

Magic Crystal, this, this is Magic Crystal!"

"Yes, this is the Magic Crystal. Chu Yun nodded slightly, and then slowly told Shi Long and Ye Qing about what he had encountered after cultivating on the boulder and meeting the Swallowing Heaven, but he only hid what he had experienced after falling into the dream, because even he himself remembered it very vaguely.

"I didn't expect that I would be lucky enough to see the appearance of the magic crystal?" Shi Long said in amazement.

"This is just a tiny fragment of the magic crystal, the real magic crystal, the degree of horror is far beyond these fragments, it can really bring people to some kind of strange and real dream, which makes people unable to extricate themselves!" Chu Yun remembered his scene in the depths of the ground, and he was still a little afraid, if he hadn't inadvertently punched and hit the magic crystal, I am afraid that he would have fallen into a dream forever.

Chu Yun got up, walked to the Demon Crystal Fragments, put the Demon Crystal Fragments into the bottle with a small porcelain bottle, sealed them, handed them to Shi Long and said, "You put away this Demon Crystal Fragments, although its power is very terrifying, but if you can use it to constantly refine the will of the Martial Dao, your cultivation will will definitely be able to improve extremely fast, and it will also be of great benefit to the promotion of the Martial Dao Realm in the future." ”

Chu Yun then took out a small porcelain bottle from his arms, handed it to Ye Qing, and said: "It's just that this magic crystal matter, don't let outsiders know, although we don't know much about its use, but since it is a thing contained in the source of the black fog, I'm afraid the value is far beyond our imagination, even if it is a member of the Cold Wind Group, don't let them know it for the time being." ”
