"Merlin Magus, I promise you all this......" Thorne Merlin glanced at Lin Yun expressionlessly, in fact, he was just curious, trying to figure out what was going on, and whether it would endanger the interests of the Merlin family, after all, this passage was stored in the depths of the Ghost Valley, and it would be difficult for him to feel at ease if he didn't figure it out.

Moreover, the terrifying strength of the young mage also made him have to compromise......

"Lord Thorne, you ......" Rahn Merlin looked at Thorn Merlin dumbfounded, he couldn't believe his ears, Lord Thorne, who has always been strong, didn't even bargain, and directly agreed to the young mage.

Isn't that a bit unscientific......

In Rahmelin's opinion, this is indeed very unscientific, he has been following Thorn Merlin to participate in the battle for the Flame Plane for a long time, and he knows a little bit about the character of this commander, and it is not an exaggeration to say that he is hot.

But now, it was a little strange that this hot-tempered commander was so docile in front of the young mage......

In fact, at the time of the Frost Keep, Rahn Merlin already knew that the Ancestral House Council had sent a commander to lead the Plane Legions on the Flame Plane with Thorn Merlin.

When he first received the news, he thought that some powerful ancestor of the ancestral land, or a member of the family council, was going to be the commander. The final result was to his surprise, the person sent by the ancestral land was actually only a young man in his twenties, in the realm of a fifth-level magician......

This made him wonder if the people in the ancestral land had taken the wrong medicine......

Otherwise, how could such a ridiculous thing be done?

In his opinion, a fifth-level magician is particularly outstanding in some aspects. Also completely ineligible for the post of commander......

And after seeing this young commander, he didn't have a good impression in his heart......

"Alright. I know what you're trying to say......" Thornmerlin glanced at Rahn Merlin impatiently, just this one. just asked the other party to shut up honestly, and then he looked at Lin Yun with an inquiring gaze: "When will you go in?"

"Now......"

When he said this, Lin Yun had already walked into the passage, and as soon as he stepped into the passage, he immediately felt an incomparably scorching heat, just like being in an oven, and there was a faint burning sensation on the skin exposed outside the mage's robe. It wasn't very strong, which made him frown, but he didn't stop, but continued to walk forward.

Soon, Thorn Merlin and the others followed......

A group of people followed the stone staircase that spiraled downward, cautiously advancing, and as they went deeper, they realized that the further down they went, the wider the passage became.

The passage is very tidy. There is no clutter, it's just that the temperature here is too terrifying, even if it is a group of them, all of them are powerhouses above the level of a titled magician. Walking along the stone staircase for ten minutes, his whole body was already wet with sweat, and the mage's robe was clinging to his body. The guide was very uncomfortable.

Soon, a group of people came to the end of the passage......

The place is very wide. It is a space with a radius of several hundred meters, and the stone walls in all directions are covered with patterns. There are candlesticks every two meters, but the candles have burned out, and the floor is paved with moonstone, which emits a faint fluorescence and subtle magic fluctuations in a dimly lit environment, and the overall arrangement here looks a little luxurious.

"What is this place......

After coming here, Thornmerlin looked around curiously, his whole face was full of surprise, and he walked through the candlesticks, staring closely at a stone wall directly in front of him, with a thoughtful look: "This should be the style of the Third Dynasty, only in that era of extreme luxury would spend so much thought on a stone wall." I really can't understand how there is such a place under the Ghost Valley, there are thousands of years of existence here......"

There were six people who came down this time, and the others, like Thorn Merlin, came here and found that there was no danger, and walked around cautiously in this spacious space.

Perhaps no one noticed that Lin Yun's gaze was always in front of him......

It's dark ahead......

But he knew there was something that made his heart flutter......

Lin Yun casually released a light technique, and suddenly a soft and bright ball of light appeared, suspended a foot in front of him, and with the light illumination, he walked forward alone.

After walking for four or five minutes, he came to the end of this space, and in front of him was a closed stone door, and a faint wave of magic came out from behind the stone door.

"It's ......"

Standing in front of the stone gate, illuminated by the light technique, Lin Yun faintly saw that the surface of the stone gate seemed to be spread with intricate patterns, and with his knowledge, he could naturally see that this should be an alchemy circle with depleted magic power. Staying in front of the stone door, staring carefully for a few minutes, he no longer hesitated, took out a low-level magic crystal from his pocket, slowly squatted down, his slender fingers groped on the stone door for a while, and soon found a groove and stuffed the magic crystal in his hand.

And then......

At the moment when the magic crystal was put in, the closed stone door trembled violently, and countless lines were activated, blooming with dazzling light, which lasted for several seconds, and as the light gradually dimmed, the stone door slowly opened.

"Okay......" Seeing this scene, Lin Yun breathed a sigh of relief, but then his facial expression froze, and he looked at Yiqiē in front of him blankly, and his heartbeat almost stopped.

Two crystal-like hedrons, inlaid on the wall, emitted a dizzying brilliance, and violent magical fluctuations spread to all corners, and at the same time, two terrifying auras slowly rose......

"Five-Colored Dragon Crystal ......"

Lin Yun recognized at a glance that these were two five-colored dragon crystals, which belonged to the legendary pure-blooded five-colored dragons, each of which contained earth-shattering magical powers, and were treasures coveted by countless mages, but in the history of the Northrend world, there were very few mages who had obtained five-colored dragon crystals.

In the time of the Nether Dynasty, it was the era of the five-colored dragon and the pure-blooded elf, and together they wrote a glorious time, and the entire Northrend world was under their control, even if the human heaven-level mage at that time had the strength to slaughter an adult pure-blooded five-colored dragon, he did not dare to take it lightly.

It was only at the end of the Nether Dynasty that strong men such as Charles the Great and the Sage of the Firmament appeared among the human race, and a vigorous battle of dragon slaying began.

But after breaking the throne of all things, the five-colored dragon and the pure-blood elf have escaped into the unknown plane, and have not appeared in the world of Northrend to this day......

At the peak of the development of magical civilization to the extreme, those mages who were powerful enough to rival the gods conquered the endless plane, but they did not find any clues about the five-colored dragon, and finally unanimously concluded that the five-colored dragon race had been completely extinct at the beginning of the Third Dynasty.

"Wait......"

Lin Yun was not carried away by joy, but concentrated on the smooth wall, and soon found that the wall was not only inlaid with five-color dragon crystals, but also engraved with a large number of runes, forming an alchemy circle with a complex structure, and those two five-color dragon crystals were the core of this alchemy array.

To be precise, this is an alchemy circle that opens the plane passage......

It's easy to guess......

The Dragon Cultivation Circle needs to be built at the junction of two planes, using two forces from different worlds to achieve some incredible effect.

It took a few minutes for Lin Yun to complete the rune cracking, and suddenly the two five-colored dragon crystals bloomed with dazzling light, and in an instant, the colored light flowed, like the sun, illuminating the space within a radius of hundreds of meters, Lin Yun, who was standing in front of the stone wall, could clearly perceive at this time that the surrounding space had obviously become distorted, and violent magic fluctuations were surging wildly, and this violent power was like a substance, and even the air made a "pop" popping sound.

At the same time, the light emitted by the two five-color dragon crystals became more and more dazzling, and the alchemy circle on the stone wall was also running wildly, and suddenly the surrounding space was distorted to the extreme, and it lasted for more than ten seconds before it slowly calmed down, and a pitch-black crack appeared, which was gradually expanding, this was the plane passage......

The last qiē returns to calm......

What appeared in front of Lin Yun was a blue plane passage, wide enough for ten people to advance side by side, standing in front of the plane passage, he could clearly feel a cold breath to the bone, and he was a little surprised in his heart, the general plane path usually separates the two planes, and this plane passage in front of him is obviously a little special......

"It is worthy of the dragon cultivation array...... At this time, even Lin Yun had to marvel in his heart, the dragon cultivation array forcibly connected two different planes with the power of a magic circle, and the plane channel was very stable, which is estimated to be only possible with the alchemy array at the peak level of the true spirit, although he can also arrange some true spirit level magic arrays, and even reluctantly, the middle-level alchemy arrays can be arranged, but compared with the alchemy arrays of this level of the dragon raising array, it is simply a heaven and an underground.

"It seems to be a little troublesome......" Lin Yun looked at the azure plane passage, a wry smile appeared on the corner of his mouth, he roughly guessed that at the end of the plane passage, it should be a plane of the same scale as the Furious Flame Plane, and in that seat plane, there was also a part of the Dragon Cultivation Array.

In other words, the magic circle in the two seats adds up to the complete dragon cultivation circle.

In the empty and decaying library, he had already memorized the theory and structure of the dragon cultivation array, the core of the dragon cultivation circle was five different five-color dragon crystals, and now there are two, and there should be one in the center of the plane channel, which is to stabilize the plane channel.
