The continuous output of aura from Gu Yueran's body directly entered the Nebula Tower, and the light green aura seemed to be fluorescent, surrounding the tower body of the Nebula Tower.

As soon as Gu Yueran made a move, she felt a powerful suction, sucking out the aura in her body frantically.

The aura consumed by refining this Nebula Tower is increasing more and more!

In the blink of an eye, it was already a grid of aura.

Gu Yueran adjusted his breathing, gradually becoming stable, and the output of the aura was also gradually stable.

The aura is like a long dragon, constantly lingering and turning, and finally enters the tower.

The pitch-black tower body suddenly cracked, very subtle, and slowly became light.

Gu Yueran had been immersed in the transformation of the aura, and by the time the aura was almost consumed, the tower body of the fourth layer had already become the same as the first three layers.

Gu Yue's eyes lit up, and he stepped up the output of spiritual energy, only to hear a buzzing sound, and a light wave visible to the naked eye spread out all around, and the circles of light spread outward with the Nebula Tower as the center.

Gu Yueran's body suddenly stiffened, and she spat out a mouthful of blood, every time she recycled the refining aura, there would be a strong impulse, this time it was even more obvious, but this time it was because she had just used her heart blood, so it should be that her physical strength was not comparable.

It stands to reason that the fourth layer should be more difficult, but Gu Yueran's refining this time is indeed not so difficult, it can be seen that the speed at which her current strength is growing is comparable to the difficulty growth of each layer of the Nebula Tower!

This is a good thing for Gu Yueran!

Wiping the blood from the corner of his mouth, Gu Yueran couldn't wait to go into the Nebula Tower to have a look, wanting to see what the fourth layer was!

It's just that as soon as his divine sense moved, Gu Yueran's whole person had already appeared on the fourth layer of the Nebula Tower, and when Gu Yueran's eyes looked at the fourth layer, his eyes widened slightly, but it was not as surprised as he imagined, because there were gold and silver jewelry, spirit stones, spiritual techniques, weapons and herbs, which seemed to be in it.

Although it's not something that Gu Yueran didn't expect, but now Gu Yueran is lacking this, and he won't refuse if he has more!

Originally, she was still a poor person, but now she has a lot of things, and if she converts them all into spirit diamonds, I don't know how much money she will have.

Not counting the gold, silver and jewelry, even the spirit stones and spiritual tips are some more precious.

The only thing that made Gu Yueran happy was that the spirit stones were almost all on top of the Xuanling Stone, and Gu Yueran even saw the existence of the Holy Spirit Stone.

Gu Yueran counted, in addition to the Xuanling Stone, there are also more Earth Spirit Stones, there are eighteen Heavenly Spirit Stones, and there are also two Holy Spirit Stones!

O Spirit Stone!

When Gu Yueran was in Dongao Country at that time, he cut out an earth spirit stone, and he could sell it for tens of thousands of spirit diamonds, and now the heavenly spirit stone and the earth spirit stone existed, and Gu Yueran could hardly imagine it.

The current Xuanling Stone does not have much effect on Gu Yueran, even if it absorbs the aura inside, it is only a drop in the bucket for her, rather than wasting it, it is better to sell these Xuanling Stones.

As for the Holy Spirit Stone and the Heavenly Spirit Stone, they may be of great use in the future!

Gu Yueran put away those spirit stones.

Now she has three more spaces besides the Nebula Bracelet.

One is the space jade pendant of the old man of the stone machine, the other is the space ring obtained from Zeng Yangchang's hand, and the other is the powerful one in the stone room.

Gu Yueran packed up all the things, and these spirit stones were enough to hold a spatial ring.

Medicinal materials and other things, Gu Yue Ran put it all into the ancient space jade pendant, and there were also things from the old man of the stone machine, all of which were related to alchemy, and Gu Yue Ran did not move.

In the end, the huge chrysalis of the Jade Emperor Honey had been moved to the Nebula Tower by Gu Yue, and that thing took up too much space, if it was given a space, wouldn't it be a waste.

Gu Yue dyed and tidied it, only to find that there were already so many things on her body!

It's just a pity that there has been little use, and she feels that it is time to use these things.

Looking at the remaining treasures, what surprised Gu Yueran was that the most spiritual tips were some sword spirit techniques, and there were all kinds of sword moves, Gu Yueran was not very proficient in sword attainments, but if he used a sword, he would definitely get twice the result with half the effort.

If you continue to look at it, you will see a bunch of weapons next to it, which are simply complete with eighteen kinds of martial arts.

But they are all excellent weapons, and Gu Yueran is now short of weapons, but there is no one in them that she can look at.

Gu Yueran picked it up and pulled it again, and finally her eyes were attracted by a tattered sword in the corner.

It was a rusty sword, with bad deeds, and no one who saw it would take it to heart, but that's it, Gu Yueran would feel strange.

It's not because of anything else, everything in it is well preserved, none of those weapons are rusty, on the contrary, they are still shiny, this Nebula Tower is a special space, so, many things can be preserved as they are, but why is there a sword with a broken iron here?

Gu Yueran frowned and slowly picked up the sword.

The sword body is ordinary, and the weight is half of it, not light, but it's not that heavy!

It's just that as soon as he picked up the sword body, the sword in his hand suddenly shook, Gu Yueran trembled, and let go, and the sword fell to the ground.

The rusty iron sword on the ground, there was a pool of bright red blood on the hilt, Gu Yue's eyes were wrinkled, and she looked at her hand, which was from falling into this hole, her hand, grinding over the stone wall, hitting the stone wall, was injured, and she didn't pay attention at the moment, but it was actually stained on the sword.

But what about that tremor?

Gu Yueran narrowed her eyes slightly, and then she glared slightly, because the blood stains on the sword's body were disappearing at a speed that was visible to the naked eye!

The blood seeped into the sword!

This sword is blood-sucking?

Gu Yueran was taken aback by this idea, but before she could confirm it again, the rusty iron sword suddenly buzzed and shook twice on the ground.

"Oh? What's going on? Is there spirituality? Gu Yueran asked with a glare.

"Buzz!"

Suddenly, the sword shook twice.

Gu Yueran's eyes narrowed slightly, and she slowly spoke: "Can you understand what I am saying?" ”

Gu Yueran waited quietly, looking to see if the sword was really spiritual.

How do you know that after waiting for a long time, I didn't see the sword move, as if what happened just now was an illusion at all!

Gu Yueran frowned slightly, slowly squatting on the ground, staring at the sword.
