Looking at the entrance to the cave that resembles a square, although the entrance space is not small, it is very secret, and it cannot be found without paying attention to observation, because above the entrance of the cave, a shadow is cast under an abrupt boulder, which just blocks the entrance of the cave.

Gu Yan looked around a little, and after making sure that there was no one, he and the smaller black spirit walked towards the entrance of the cave.

As soon as he walked in, Gu Yan immediately felt a huge contrast in the temperature around him, outside the cave, because of the abrupt boulder blocking the sunlight, it looked relatively dark and a little damp, but as soon as he entered the cave, a hot breath wafted in front of him.

After entering the entrance of the cave, there was no sunlight, but through the slightest reflection of light, you could faintly see the black giant stone pillars, those stone pillars were almost red, exuding a scorching aura, and even the air became a little distorted when Gu Yan looked over.

Gu Yan took out the animal skin again, looked at the route instructions on the animal skin, and stepped a square rock again.

"Click!"

The sound of a mechanism activating sounded, and the rock behind the ancient rock immediately sank, and a deep ravine appeared on the ground, but under the ravine, it was not black, but a red color, and streams of scorching gas erupted, and the temperature around it rose sharply.

Gu Yan glanced at the ravine, and was instantly stunned, under the ravine, there was a blazing magma. And above the ravine, huge cones formed by stone pillars face downward, giving people the feeling of being in hell.

"Who the hell would it take so much effort to arrange all this!" Gu Yan muttered secretly in his heart, but Gu Yan was full of joy about this magma.

Because in this way, it can be said that it provides a good condition for the development of the ancient dragon tribe. Although the Ancient Continent refines high-grade elixirs and crystals, it requires an artifact or a Dan master to possess alien fire or beast fire.

But how can alien fire and beast fire be easily obtained, and the number of alien fire and beast fire is extremely rare, the tens of billions of people in the ancient continent, martial artists account for most of them, so many crystals and pills are refined, wouldn't it exhaust them to death.

However, for most forces, such as Huoyunmen, one of the five hegemons of the Far East, it is to establish a refining workshop and a Dan Pavilion within their own sect. The most important thing about building a refining workshop and a Dan Pavilion is that the temperature of the geo-core magma is extremely high, and only the geo-core magma can provide sufficient temperature.

The temperature provided by the magma in the center of the earth is enough to melt the materials for refining ordinary king-level intermediate crystals, and alchemy is similar. That's why Gu Yan was so excited when he saw these red-hot magma.

Because magma in the center of the earth is almost an unattainable treasure, it can only appear in extremely hot places, otherwise it can only be obtained in volcanoes and the center of the earth, and the danger of doing so is not small.

And Gu Yan looked at the ravine, then turned his head, looking at the nine giant stone pillars in front of him, and the temperature around him had risen to an extremely high level at this time, Gu Yan's robe would have been burned to ashes if he hadn't used his true yuan to resist the scorching heat.

Looking around, I saw a small black tower appear in Gu Yan's hand, with a flash of golden light, two tall figures appeared in front of Gu Yan, and as soon as these two figures came out, they were immediately attracted by the nine stone pillars in front of them.

"Gu boy, where are you, how can it be so hot, this temperature is really a bit unusual!" Ghost Ku immediately asked Gu Yan.

However, before Gu Yan could answer, Tuoba Hong said, "It turned out to be the Jiuyang Forbidden Yuan Array, and every array of Dharma Pillar Stones is made of Yanyang Jade, this is not a small stroke!" Tuoba Hong's tone was filled with surprise.

Gu Yan was really impressed by this Tuoba Hong's insight, and he actually saw this Nine Yang Forbidden Yuan Array at a glance, and also saw the materials of the Nine Array Pillars. This is definitely not something that ordinary people can do, and only people like him who have lived for tens of thousands of years will have it.

"Jiuyang Forbidden Yuan Array, isn't this a high-level formation of your human race. Yanyang Jade, but it is not bad, and it is also nine such complete Yanyang Jade, which is enough to create a set of emperor-level crystals. A strange look flashed in the ghost's eyes, looking at the nine stone pillars in front of him.

However, Tuoba Hong on the side snorted coldly, "Do you think this Nine Yang Forbidden Yuan Array is easy to break? If you want to obtain this Yanyang Jade, you must break this formation, otherwise it is all empty talk." ”

Gu Yan watched the two elders keep arguing, and he didn't interject, because he found that the two old guys had been discussing how difficult this formation was.

At this time, Gu Yan looked helplessly at the two who were discussing fiercely, "Sacrifice, ghost elder, is this formation so difficult to break?"

The ghost elder glanced at Gu Yan, but Tuoba Hong looked at Gu Yan patiently, and said softly, "Lord, this Jiuyang Forbidden Yuan Array is a kind of formation in ancient times, although the conditions for arranging the formation are not difficult, but the reason why this formation is famous is its blocking ability and defensive power. ”

"Especially this Nine Yang Forbidden Yuan Array, the Nine Formation Base Pillars are the Yanyang Jade that refines the Emperor-level crystal, and it has an extremely strong gathering ability for fire attributes, so if this Nine Yang Forbidden Yuan Array insists on breaking the formation, even if it is me, it will take a lot of effort. Tuoba Hong looked at the nine pillars.

The Daimyo Ancient Rock of Yanyang Jade has naturally heard of it, and there are detailed records of this material in many ancient books. Yanyang jade is the essence of the Yanyang Stone, that is, the extremely pure and high-quality Yanyang Stone.

For martial artists who cultivate fire attribute exercises, cultivating on the jade platform built by Yanyang Jade can not only achieve several times the cultivation speed, but also have unimaginable miraculous effects on the advancement of the exercises.

At this time, Gu Yan looked at the nine formation base pillars of the Jiuyang Forbidden Yuan Array, and he could imagine the harvest of this trip. Even if there is no super vein, the value of these nine pillars is enough to make the trip worthwhile.

"Gu boy, where are you now? Are you trapped in this formation? If so, it would take a lot of effort to take it out!" Oni Ku looked at the blazing rock walls around him, and his face showed a solemn look.

Although the temperature in the cave was already very high at this time, for Ghost Ku and Tuoba Hong, it was completely possible to ignore it without the slightest true element to resist. The physique of the demon clan is known as the strongest physique, but it is not blown, not only can resist high-level crystals, but even if it is a flame and ice, it has a strong resistance effect.

"Ghost elder, sacrifice, you think too much, this is a secret place recorded on a piece of animal skin, there is a super ore vein in this Jiuyang Forbidden Yuan Array that has been banned by this formation, so the Heaven and Earth Yuan Qi in the mountain range where my clan is located is extremely thin. ”

"I want to break this Nine Yang Forbidden Yuan Array, unseal that barren stone vein, and then establish the clan on this mountain range. "Ancient rock is the color road.

"What? A super barren stone vein has been banned, no wonder it has cost such a huge amount of money, and he does not hesitate to use the Yanyang Jade as the base pillar of the formation. In this way, it will be even more difficult to crack this Nine Yang Forbidden Yuan Array. "Ghost withered tsk.

Banning a super barren stone vein, relying on the energy of the barren stone vein, is enough to increase the defensive power of this formation to the extreme, and if you want to crack it, the difficulty will undoubtedly double.

However, Gu Yan smiled, Ghost Elder, "Is this formation so difficult to break?" The reason why I called you out is because I already have a method to break the formation, and I only need you to help me from the side." ”

Saying that, Gu Yan learned about the Lingzun formation in his hand, and the ghost withered glanced at it slightly, and said with some idiocy, "It's really confused, I forgot that your kid has the inheritance of that Lingzun guy, and it's not easy to crack this formation." ”

Gu Yan chose the second of Lingzun's three methods for cracking the Jiuyang Forbidden Yuan Array, although it was not the easiest one, but in order to protect this mountain range from being destroyed, Gu Yan could only choose the second one.

According to the description of the Lingzun Formation, the best way to crack this Nine Yang Forbidden Yuan Array is to cut off its connection with the foundation of the formation. As long as the connection between the formation and the formation foundation is severed, it will not be possible to rely on the formation foundation to absorb more energy to maintain the operation of the formation, and in this way, this Jiuyang Forbidden Yuan Array will be unjustly broken.

However, because the foundation of the formation is generally established within the formation, the method of Lingzun is to borrow the concept of rebirth after death. Ordinary people don't dare to enter the Jiuyang Forbidden Yuan Formation, for fear of being harmed by your terrifying temperature, but more importantly, they are afraid of being trapped in the formation.

It can also be seen from this that Lingzun's name as a god in this formation is not in vain, this kind of idea of breaking the formation, and being able to come up with this method, must have been tried at risk, and Lingzun is a martial artist in the Jindan period, and it is indeed admirable to have such an adventurous spirit.

However, the key to breaking the formation is to cut off the connection between the main body of the formation and the base pillar of the formation from the inside. And according to the terrifying level of this formation, I am afraid that ordinary Divine Soul Stage masters would not dare to enter.

However, for the two of them, Ghost Ku and Tuoba Hong, especially for Tuoba Hong, a figure whose strength is several times that of the Great Emperor, there is no need to worry about the threat of the terrifying temperature inside.

But for the ghost wither, although the strength is a little lacking, don't forget, it is also the demon body of the demon clan, and it is more than enough to resist this temperature.

Tuoba Hong and Ghost Ku looked at the method recorded by Lingzun again, and then nodded at Gu Yan.

However, Gu Yan smiled and put his two hands on the shoulders of Ghost Ku and Tuoba Hong, "Sacrifice, Ghost Elder, if it is superfluous, I Gu Yan will not say much, safety is the most important." ”

Ghost Ku looked at Gu Yan and smiled, "Gu boy, when did you become such a mother-in-law, isn't it just a formation." For this formation, I really want to test how powerful it is. As he spoke, he looked at Tuoba Hong. As soon as the two of them jumped, they entered the Nine Yang Forbidden Yuan Array.

As soon as Oni Ku entered it, his body was immediately bent by the huge energy, but Oni Ku's huge black hand pressed to the ground, supporting the entire falling body, and a smile appeared on his face.

Looking at the ghost wither, Gu Yan was also shocked in his heart, but he knew very well about the strength of the ghost wither, especially the strength of the demon body. But it was directly pressed down, which required a lot of energy.

However, compared to the ghost wither, Tuoba Hong seemed extremely relaxed, stretched out his hand and pulled the ghost wither, and then the two of them walked towards the center of the nine foundation pillars!
