Gu Yan tried to use the aura to test the surrounding environment, but she didn't find any mechanism or place that could be triggered, suddenly, she looked at the base of the Dan furnace that had been abandoned, revealing a thoughtful expression, and other book friends looked at it normally.

The Dan furnace there had been removed, and now there was only a pile of rubble left, and there was even a trace of green smoke on it, and Gu Yan sensed the subtle traces of the aura from here. It's just that at the beginning, the fluctuations of the aura were hidden by the pile of rocks, so she didn't notice it.

The pile of stones was used to gather fire during alchemy, and the smoke produced had the effect of covering the aura, and when Gu Yan moved the stones away, he sensed that there was a trace of aura circulating there.

It doesn't seem to be a spiritual energy hole, just a hole, from here you can get a glimpse of an invisible spiritual vein underground, and the spiritual energy is constantly circulating there. Gu Yan carefully understood its position, took out a piece of dry wood with his other hand, and then kept drawing on the ground. After I don't know how long, she suddenly slapped her forehead, "So that's it!" ”

If she guessed correctly, the eight stone rooms in the underground palace should all have their own uses, but now the things inside have been emptied, I don't know if it was done by the owner of the tomb at that time, or by people later. But this is actually an extremely delicate formation. This formation is not used to trap people, but to repel the enemy.

The direction of the aura in the underground is actually an extremely delicate array, each stone chamber hides one such eye, and then it is gathered by eight eyes in the center, Gu Yan estimates that the altar is the central array eye. As long as this array is destroyed, then the eight stone chambers will be closed on their own, and they must be opened with specific sigils. This may have been a means for the owner of the tomb at that time to protect himself. But how did he get sucked into this stone chamber? But Gu Yan was puzzled. This mausoleum is still too mysterious that I can't see clearly. She thought about it for a long time, and probably only Jiu Zhiding could explain. The Nine Peaks Ding has some connection with the chaotic space in its body, and this Zhending Divine Beast is the guardian spirit bird of the underground palace, maybe it will automatically recognize the master. When there was an explosion in the dungeon, bring yourself to this safe place?

Gu Yan smiled bitterly and patted the spirit bird's head, "You're causing me a problem,:." "Originally, she was in the main hall of the underground palace. Even if the thunderbolt explodes in the dry sky, she has a magic weapon to protect herself, and there will be no risk of serious injury. But now he is trapped in this stone chamber. Don't know how to get out. And she didn't know how long they would stay underground, in case they only stayed for a few days and left, then after the entrance to the ancient tomb was sealed, she would really be trapped here and couldn't get out.

She thought about it, but she didn't have much to do, and at this time, she suddenly saw the sycamore tree. Lying on the stone couch, shining with moon-white silver light. She remembered what Zhancheng had said, the lack of moon sycamore and the seven-star lamp. The Guiyuan Arrow is three mysterious things related to this ancient tomb. He used the longbow turned into a moonless sycamore that day to shoot the Guiyuan arrow, and then he lit the seven-star lamp and opened the door of the ancient tomb, so can he also brew it in the same way today to see if he can break the ban of this stone room?

She stood up and walked around the stone chamber with some excitement, feeling more and more that this idea was feasible, and the spiritual veins in the ground were intricately traced, like thousands of locks that were intertwined and could not be opened at all. Gu Yan didn't dare to move lightly, in case it triggered any more powerful bans, it would be too late to regret it. Come to think of it, this is the only way to do it.

It was only when she took the sycamore wood in her hand that she found that it had been banned by Zhancheng with the secret method in the Demon Gate, and she couldn't control this treasure at all. Gu Yan frowned, this would be a little troublesome.

It's not that there is no way, as long as the mark left by Zhancheng himself on it can be completely erased, but both of them are monks of the same level, and their cultivation is almost the same, and if they want to erase the mark under Zhancheng, they can only be slowly tempered with true fire. But this also has the advantage that this sycamore wood can be completely refined and connected to one's own mind, just like a natal magic weapon. Even if you encounter Zhancheng again in the future, you don't have to worry about being taken in by him again.

It's just that in this way, the amount of work required has increased greatly, even if Gu Yan's cultivation is refined now, with her skilled alchemy and refining techniques, she still needs to open the furnace and use the true fire to refine for nineteen days. So now there is only prayer, I hope those people in Zhancheng will not leave so soon!

Gu Yan also thought about it at this time, anyway, the years of cultivation are endless, even if he is really trapped here for dozens or hundreds of years, it is nothing, if he is really the only one left here, then he can also explore the underground palace, maybe he can meet a greater opportunity waiting for him,:!

After making up her mind, she was no longer in a hurry and began to make all kinds of preparations before the sacrifice. It was a very long process to refine the Sycamore without the Moon, and before that, she had to take care of a few things. Gu Yan flashed and advanced his own chaotic space.

After the knot, this space has been very stable, and the aura inside is also extremely strong, Gu Yan first came to the purple flower and looked at the silent words that were sleeping here. She was surprised to find that her body was automatically absorbing the aura. Gu Yan checked her body, and there was no sign of decline. It was as if she was in a state of slow self-cultivation. This made Gu Yan very surprised. Speaking of which, although Mo Yan is a dual spiritual root, in Cangwu, such a qualification is not good, but he can reach a self-cultivation realm that only foundation building monks have, is it caused by the aura in the chaotic space?

Speaking of which, this is the first time she has put someone in the chaotic space, so there has never been a precedent to follow, Gu Yan is just not at ease, afraid that she will starve to death here because of lack of water, and now it seems that there is no such danger, so she put her mind at ease. Looking at Xiao Jiang again, he found that the big white cocoon had become thinner and thinner, and the outline of the shadow inside could almost be seen from the outside.

Looking from the outside, Gu Yan felt that Xiao Jiang's body was a lot bigger than before, and as for the rest, through the white cocoon, he couldn't see anything for the time being. Knowing that its promotion is almost complete, you can rest assured. She looked at another place, which was some ancient spirit roots that she had taken from Qiyun Mountain, which could not be cultivated in the outside world, so they were all placed here, which were the best materials for alchemy.

It's just that in this chaotic space, it seems that even the growth rate of the spirit plant is much slower than that of the outside world, and those spirit roots are only just germinating now, and it will take at least ten years of hard work to grow into a mature man. Anyway, there is its own wind, frost, rain and dew here, so you don't need to worry too much about Gu Yan. Seeing that everything was ready, she came out of the space again, and then put the Nine Peaks on top of the pile of rocks.

Although Gu Yan has discovered all the peculiarities of this treasure tripod, it is really a rare treasure, and some of the wonderful uses are even uncomprehendable now, but emotionally, she is still willing to use it as a Dan furnace, which symbolizes a memory when she first came to Cangwu.

And although she can't destroy the chaotic vitality in the ding, she can use it directly when she is alchemy, which makes her alchemy even more effective, and other book friends read it normally:. Gu Yan took a deep breath, and then lifted the lid of the ding, the spirit bird still looked dull, Gu Yan took a look at the dingkou, a ball of purple gas was steaming inside, and the patterns on the inner wall were faintly visible, Gu Yan waved her hand, and a ball of green gas erupted from the dingkou, and then she threw out the sycamore wood.

The lack of moon sycamore in the air circle, quickly turned into a small branch like a little finger, and then fell straight into the mouth of the tripod, the lid of the tripod immediately "snapped" shut, the pattern of the tripod body suddenly became active, and the temperature of the whole tripod rose rapidly.

Gu Yan sat there cross-legged, her two hands in the shape of holding the moon, and the four fire spirits were skillfully controlled by her at the same time, constantly rotating at the bottom of the Nine Peaks, this was her own unique fire control technique, which even the Bixia Sect Patriarch who created the Dan Dao back then could not control.

Being in this stone chamber, the days are long and eternal, and he doesn't know how time passes, while Gu Yan is just focusing on the Dan furnace in front of him. Under the refining of the four flames in turn, a trace of black smoke slowly began to float from the Dingkou, which looked similar to the black swamp mist emitted by Zhancheng. With an extremely thick air of death.

After the smoke rose to the mouth of the ding, it was swallowed into the stomach by the spirit bird lying on the lid of the ding, which made Gu Yan a little crying and laughing, this divine beast that was ambushed by himself was like a pixiu, no matter what he saw, the first reaction was to swallow it in his stomach first.

It took ten days just to refine the black qi on the sycamore wood, and then, Gu Yan put a drop of his essence blood into the ding, refining it into something connected to his own blood. In this way, unless someone with a higher level of cultivation completely erases the mark with a great divine power, he will never be able to take away this thing. Zhancheng was in too much of a hurry and didn't have time to use this method to make Gu Yan pick up such a bargain. This time it took another five days.

By the end of the fifth day, it was basically done, but Gu Yan had a whim, and she began to transform the shape of this sycamore tree. And refined it into the shape of a longbow, according to what she saw that day, the longbow that Duan Yingsleeve was carrying. This can't help but be said to be a bit of a bad taste, Gu Yan also wants to know, when she and Duan Yingsleeve use the same longbow and send out the same Guiyuan arrow, I don't know who is more powerful?
