Originally, in this Dan room, it was not only the Dan furnace that Wang Tao was observing now, but the others were not only much smaller in size, but also lost their aura, and they were damaged at a glance.

Only this one in the middle is well preserved, but at first glance, there is a sense of vicissitudes of antiquity in my heart.

And this feeling, Wang Tao has only felt it on the Dan Soul Appeal Sword used by Shi Qionghua.

"Could it be that this Dan furnace is a Dao vessel!?"

For a while, Wang Tao couldn't hold back the ecstasy in his heart, and he passed through the system a little nervously and checked the attributes of the Dan furnace.

Item Name: Eight Desolations Refining Immortal Furnace

Quality: Lower grade device

Effect: The success rate of refining elixirs below the spirit level is 100%, the success rate of refining elixirs of spirit rank quality is increased by an additional 50%, and the success rate of refining ground level elixirs is increased by an additional 30%.

"It's really a Dao Weapon! And it's a Dao Instrument Dan Furnace!"

Wang Tao was simply ecstatic in his heart, he actually found the Dan Room of Sky City by such a coincidence, and then found the Dao Instrument Dan Furnace inside!

Moreover, the special effect of this Eight Desolations Refining Immortal Furnace is also very against the sky.

Wang Tao knew that if he wanted to upgrade his alchemy, he would only gain a considerable level of proficiency when he successfully refined the same or higher quality pills.

And now the Eight Desolations Refining Immortal Furnace has forcibly increased the success rate of Wang Tao's refining of Xuan-rank pills to 100%!

Then this also means that as long as Wang Tao has enough materials, even if he raises his alchemy by a whole level and becomes a spirit-level alchemist, it will be very easy!

Perhaps, not even half a month.

The first characteristic alone was enough to make Wang Tao ecstatic, not to mention the extremely terrifying bonus effect of facing the elixir of the spirit level and earth level behind the Eight Desolation Refining Immortal Furnace.

The reason why the Spirit Rank Pill is much more precious than the Xuan Rank Pill is that in addition to the fact that the required medicinal materials are more rare and difficult to find, the success rate is outrageously low, generally less than 5%.

But Wang Tao now has the Eight Desolations Refining Immortal Furnace, once he becomes a spirit level alchemist, the lowest success rate will be 50%!

This number will be ten times that of an ordinary spirit level alchemist.

After the Eight Desolations Refining Immortal Furnace was also included in the Ruyi Ring, Wang Tao carefully swept the Dan room again, trying not to let go of any corner.

At the same time, Wang Tao couldn't help but think about some questions in his heart.

Judging from the whereabouts of the disciples of the Temple, it seemed that their target was not this very secret Dan Room, but another place in the Sky City.

And where their target is, it is very likely that there is also a Dao artifact, otherwise it will never allow the disciples of the Temple to try to unite all the sects of the Righteous Path to obtain this object.

Even when the alliance failed, the temples also colluded with the Flame Qilin of Heavenly Sword Island to attack a large number of disciples from various sects in order to block their plans to come to Sky City.

With such a great deal of effort, there must have been enough accurate information, and the goal must be very significant.

"Maybe there's a second Ancient Dao Weapon in this Sky City?"

In doubt, Wang Tao checked the entire Danfang and confirmed that there was nothing missing, so he prepared to take out the dragon slaying knife again, break through this mysterious wall, and leave here.

But at this moment, there was a voice in the Dan room that was extremely vicissitudes: "Little guy, where did your knife come from?"

This sudden change almost scared Wang Tao out of a cold sweat.

I had just checked the Danfang and confirmed that no one was hiding in the dark, so where did this voice come from?

Wang Tao turned his head, looked around carefully, and even secretly used the Vientiane Sky Eye Vision, but he still didn't find anything.

And this voice, although the first feeling came from behind me, after careful consideration, it seemed that it was not the case, but at the same time from every place in the Danfang at the same time.

"Could it be a hallucination?"

Wang Tao couldn't help but have this thought in his heart.

But at this moment, the voice that had been extremely vicissitudes of life before slowly floated again: "Don't look at it, with your current cultivation, unless I take the initiative to show up, you won't be able to find me." ”

"In that case, why don't you show up?" Wang Tao looked around vigilantly, and at the same time replied boldly.

The voice of vicissitudes did not appear immediately, but fell into silence, as if thinking about whether to agree to Wang Tao's proposal.

A moment later, in the Dan room, in front of Wang Tao, a black shadow suddenly appeared, this shadow had a humanoid upper body, and below the waist was the appearance of a sword.

"You are?"

As a result, Wang Tao was even more puzzled.

In the "Thousands of Worlds" written by the Pure Peak Sect, it is said that there are six races in the world: immortals, humans, demons, ghosts, demons, and beasts, but now Wang Tao is telling which clan this guy in front of him belongs to?

"I am a remnant soul of the Heavenly Sword Spirit. ”

The black shadow glanced at Wang Tao with a squinting expression, and then replied lightly.

"Heavenly Sword?"

After Wang Tao heard this name, his eyes widened even more, and he only felt that the black shadow in front of him seemed to have a great connection with his dragon slaying knife.

When the black shadow saw Wang Tao behaving like this, he immediately knew that he didn't know anything about himself, and his expression was slightly disappointed, and then continued: "It seems that you don't know the origin of the dragon slayer knife in your hand, since this is the case, I will briefly introduce it, and I hope that when the time comes, you will also tell me what you know." ”

"Your Dragon Slaying Knife, like my Heavenly Sword, was originally one of the top ten artifacts of the ancients, and it was on a par with the famous Pangu Axe and Houyi Bow. ”

"However, in a catastrophe a billion years ago, three ancient artifacts were damaged to varying degrees, and the two ancient artifacts were missing. The Heavenly Sword was one of the three artifacts that were damaged, and the Dragon Slayer was one of the missing items. ”

"After the Heavenly Sword was destroyed, less than one-ten-thousandth of the fragments remained in the world, and finally fell into the hands of an immortal monarch after several turnovers. ”

"After this Immortal Monarch obtained the fragment of the Heavenly Sword, he immediately fled from the Immortal Realm and came to this Holy Mang Continent, and then dived into his heart, trying to repair the Heavenly Sword. ”

However, after countless failures, the Immortal Monarch finally gave up on repairing and refined the fragments of the Heavenly Sword into the skeleton of the Sky City. ”

"So now I am not only a wisp of remnant soul of the Heavenly Sword Spirit, but also the core component of Sky City, and the entire Sky City is under my control. ”
