For a long time, Wu Yan had been troubled by the fact that the Great Yan Xuan Immortal 'Cave' Heavenly Spirit Domain he had refined was unable to accommodate the creatures of the outside world for a long time. This distress naturally comes from the incompleteness of the laws of this 'hole' Heavenly Spirit Domain.

The reason why there was an incomplete law in this 'hole' Heavenly Spirit Domain, Wu Yan guessed that it had a lot to do with the fact that it was forcibly broken into several broken 'holes' in the first place. Although he later used the Hong'meng' world to refine this 'hole' heaven together, the broken law was not completed.

Wu Yan also speculated that if it was possible to refine the entire 'cave' heaven into a huge space magic circle, would it mean that this problem could be solved.

And according to what Zhou Shanzhu once told him about refining ten treasures of mending heaven and town yuan with the Great Wilderness Yuan Ding, in fact, these ten treasures of mending heaven and town yuan, according to Wu Yan's understanding, is to use these ten treasures to break into the world of Hong 'Meng', and according to the method of arranging the forbidden array, the world of Hong 'Meng' is restored to the world of Hong 'Meng' Metaverse.

That being the case, then you might as well take the Great Yan Zhuxian 'Cave' Heavenly Spirit Domain as the object of the experiment to see if this method can be used.

The "Nine Palace Bagua Array" is the 'gate' space array that Xuan Yazi is best at, although the "Nine Palace Bagua Array" he refined in Hunting Sea City at the beginning was only level four, but as long as there are materials, with the refining experience left by Xuan Yazi, refining a higher-level "Nine Palace Bagua Array" should not be a difficult thing for Wu Yan.

It's a pity that Wu Yan doesn't have a seventh-level refining array material on his body. At the beginning of Lingxu City, he only had time to buy a large number of fourth- and fifth-level materials and some sixth-level materials. Moreover, with his financial resources at that time, it was impossible to purchase seventh-level materials.

It seems that the only way to find someone else is to find a way to see if they can 'get' some level 7 materials. The value of the seventh-level material is so high, it can be imagined, although it cannot be compared with the seventh-level immortal grass, but there is no problem in exchanging it for the fifth- or sixth-level immortal grass or elixir.

The spirit crystals that Wu Yan can get his hands on now are only 60,000 medium-grade spirit crystals, and if they are converted into top-grade spirit stones, there are almost close to 700 million. Although this amount seems terrifying, if it is really used to buy seventh-level refining array materials, it will not be able to buy much.

What's more, this time, he not only needed to buy seventh-level refining materials, but also sixth-level refining materials for hand training. He is only a fifth-level formation mage now, and although he knows the method of refining the seventh-level "Nine Palace Bagua Array", it does not mean that he can refine the seventh-level "Nine Palace Bagua Array".

He had to start by refining the array flags of the fifth-level and sixth-level "Nine Palace Bagua Array" respectively, and after he had thoroughly practiced it, he could refine the seventh-level "Nine Palace Bagua Array".

"It seems that this is the only way to go. "Wu Yan's gaze looked through the magic circle of the 'Medicine' Garden and looked at the bottom of the crater valley below.

Under that first-level immortal array, there was an extremely high-grade flame leyline, and in the center of that flame leyline, there was a black 'colored' fire rock island. Wu Yan observed with vertical eyes, on that fire rock island, there was a faint breeding of the source of the fire of an immortal-level yang fire the size of a human head.

Wu Yan guessed that the source of this flame was probably conceived by the owner of this place who stayed here and used this flame vein. Originally, Wu Yan's goal was to take all the source of this fire for himself. Now it seems that if you want to 'get' the sixth or seventh level of refining array materials, you can only use this source of fire to exchange them from the hands of those people.

Fortunately, the source of this flame was only a quarter of its size, enough for him to use to enhance the fire power of the Sun's True Spiritual Fire. Of course, if you can devour all the source of this entire fire, you will definitely be able to raise the fire power of the Sun True Spirit Fire to the extreme, and even directly promote it to the god-level Fire Sun True Fire, it is not impossible.

After a moment of deep groaning, Wu Yan gritted his teeth and decided to do so.

Whether it is for this 'medicine' garden, or to leave the second layer of forbidden land with these people, go to the third layer, and 'exchange' the source of fire for refining array materials, it is obviously the best solution.

Thinking of this, Wu Yan first carefully put away all the ripe immortal grass and immortal fruits in the entire forbidden land, and left those immature immortal grasses and immortal fruit spirit roots in their original places, waiting to be moved to the 'cave' Heavenly Spirit Domain before cultivating, and then walked out of the forbidden array.

Wu Yan released his divine sense, covering the entire mouth of the crater, and after scanning for a while, he noticed that the cracking of the forbidden land of the other three 'medicine' gardens was in full swing, but no one had been able to break the forbidden formation so far.

Judging from the overall progress, the Demon Immortal Alliance seems to be the fastest, followed by the Ice Temple, the monks of the Sand Sea Gang, and not even a third of them have been completed. That Kou Biao was cursing while supervising his disciples to break the formation at the moment. Originally, Fang Yuan defected to their Shahai Gang, which made Kou Biao quite excited and surprised, but as soon as he turned around, Fang Yuan was robbed by the Wan brothers.

In fact, Kou Biao even hated Wu Yan at the moment, if Wu Yan hadn't called him to the space rift, this situation would not have happened.

After Wu Yan probed for a while, he sent a message to Leng Yao, Shi Lao Demon and Kou Biao with his divine thoughts. When Wu Yan sent out the message, he didn't say any nonsense, and directly said that he would exchange the materials of the sixth or seventh level with conditions that the three of them could not refuse, and if anyone was willing to change, they could come to his 'medicine' garden to negotiate in person.

After sending out the divine thought transmission, Wu Yan stood on the edge of the crater valley for a long time, waiting for the reply of the three of them.

And as his divine thoughts were transmitted, the reactions of the three of them were obviously a little different from Wu Yan's previous thoughts. At first, none of the three of them responded to Wu Yan, nor did they send anyone over to contact Wu Yan, but every once in a while, they would glance at Wu Yan with their divine thoughts, obviously observing the reactions of others.

You must know that this time when entering the forbidden land of the Spirit Ruin 'Medicine' Valley, although everyone has brought enough sixth- and seventh-level materials, and even eighth-level materials, these things are obviously prepared for the formation mages hired by their respective sects.

After entering the third layer, the lowest level of prohibition encountered may also exceed the fifth level. If the array mage wants to break the prohibitions in the forbidden land, he must refine the sixth or even seventh level forbidden array. Outside, ordinary fifth-level formation mages simply don't have the financial resources to purchase these high-grade materials to practice. But when you get here, you can practice with high-grade materials for free.

This is also the main reason why many formation mages are willingly hired and come here. Just like those high-level elixir masters and Dan kings. After their respective 'medicine' garden forbidden places are broken, I'm afraid it will also be the busiest time for those alchemists.

However, someone soon broke the deadlock, so that Wu Yan would not be too embarrassed.

The person who came was Leng Yao. The 'Medicine' Garden occupied by the Ice God Temple was only a few hundred miles away from Wu Yan's side, and Leng Yao quickly galloped to Wu Yan's side. And as Leng Yao broke the deadlock and came to contact Wu Yan, Kou Biao and Shi Lao Demon also stopped what they were doing, released their divine sense, and quietly paid attention to this side.

They obviously wanted to see Leng Yao's reaction before making a decision.

"Wu Daoyou, I have a lot of extra sixth or seventh level materials here, I don't know what Wu Daoyou said before, in exchange for conditions that we can't refuse, what kind of conditions are they? Leng Yao's expression was still so cold and indifferent, but the tone of voice with Wu Yan at this time was very polite.

Wu Yan smiled and didn't speak, but said to Leng Yao with a divine thought: "Leng Fairy, I don't know how many sixth- and seventh-level materials can be exchanged for the top-level immortal-level yang fire from the fairy?"

"What? You have an immortal-level yang fire? What kind of fire? Can you let me see?" Leng Yao's originally extremely calm feelings suddenly became a little 'agitated' when she heard Wu Yan mention the immortal-level yang fire. Obviously, Leng Yao knew very well how rare the immortal-level Yang Fire Flame was.

Wu Yan smiled and said, "Leng Fairy, you haven't answered Wu's question yet, but you asked so many questions in one go, which made Wu a little embarrassed." ”

Leng Yao was slightly stunned, and a trace of blush suddenly appeared on her cold pretty face, which made her whole person suddenly become brilliant and 'forced', and the beauty was suffocating, even Wu Yan couldn't help but look stunned.

Seeing Wu Yan looking at her in a daze, the flush on Leng Yao's face spread more and more. She coughed lightly and said, "Wu Daoyou is right, I asked abruptly. If Wu Daoyou is really willing to take out the immortal-level yang fire seed, as long as the condition is not too bad, I am willing to use all these materials to 'handover' for exchange. Wu Daoyou, can you take a look?"

As he spoke, Leng Yao handed a storage ring in his hand to Wu Yan. She has a lot of trust in Wu Yan. However, Wu Yan didn't reach out to pick it up, but directly swept the materials in the storage ring with his divine sense.

After looking at the storage ring in Leng Yao's hand, Wu Yan did not show any joy or loss on his face, he was very indifferent. However, he still smiled and said to Leng Yao: "Fairy Leng, please forgive Wu for being blunt, this material is indeed level six and level seven, but most of them are level six, and there are very few level seven ones." ”

Leng Yao said with some embarrassment: "Actually, our Ice God Temple still has a lot of sixth- and seventh-level materials, but those are all prepared for our array mages. Entering the third layer, our array mage still needs to use these materials to refine the array plate and array flag, and try to break the prohibition inside. ”

As soon as Leng Yao said this, Wu Yan couldn't say anything else. In fact, the materials in Leng Yao's hands were enough for him to practice. It's just that there seems to be a shortage of seventh-level materials, and if the refining process fails, if Kou Biao and Shi Lao Demon don't come to 'trade', he won't have any backup materials to use.

"Well, if Leng Daoyou is willing to 'exchange', you still need to add some things. Wu Yan thought about it and said.

"No problem. Whether it is fairy grass, elixir, spirit stones, spirit crystals, whatever Wu Daoyou wants, I can take it out. Now, Wu Daoyou can let me see the immortal-level fire you want to use to 'exchange', right?" Seeing Wu Yan agree, Leng Yao couldn't help but purse his mouth and raised slightly, rarely 'showing' a smile for the first time. It seems that because of her long-term cold face, her smile is very beautiful. Divine sense, in her starry eyes, there is also a rare 'reveal' of a trace of fiery anticipation.

Wu Yan stretched out his hand and pointed to the crater valley below, and said, "Leng Fairy, the fire I want to 'handover' is below here." ”

"Wu Daoyou, aren't you entertaining me?" Leng Yao heard Wu Yan say this, and the smile that was originally 'revealed' instantly froze on his face, and his voice was extremely cold. This ice beauty is obviously angry - 32523 + dsuaahhh + 24476343 - >
