In front of the Ding furnace, Tao Hao stood still, but did not open the furnace, but was a little hesitant.

"What's wrong? Senpai?"

"Little Brother Mu is Tao's life-saving benefactor, repairing the broken sword, Tao is duty-bound, but everything you see next must be kept secret, and you must not say it!" Tao Hao said with a serious face, staring at Mu Tianyi.

"Okay, I, Mu Tianyi, swear that I will never divulge everything I see, otherwise the sky will thunder!" Mu Tianyi stretched out three fingers and swore.

Tao Hao nodded with satisfaction, and then began to seal his hands, and as the handprints flipped over, the Ding furnace in front of him was lifted.

"Click, click" came the friction sound of the gears turning.

From the ground slowly rose another Ding Furnace, completely different from the previous Ding Furnace, this Ding Furnace looked very ancient, and it was covered with strange runes.

As soon as he appeared, he made a buzzing sound, as if he was venting his dissatisfaction with living underground for a long time.

Tao Hao stroked Gu Ding and said slowly: "This is the Fire God Refining Heaven Furnace, the furnace has its own space, even an artifact can be smelted, but if you want to refine an artifact, you have to send the broken sword into the core of the Heaven Refining Furnace, where there is a lot of danger, and if you are not careful, you may destroy the weapon! So far, no one has been able to enter its core."

"However, even if you don't enter the core, you can refine the best weapon, although the grade may be slightly worse, but it is safe and has a high success rate. ”

"You must put the broken sword away in an hour, or you won't be able to get out!"

Mu Tianyi nodded slightly, took out the broken sword, and waited for the Fire God Refining Heavenly Furnace to open.

At the moment when the Vulcan Refining Heavenly Furnace was opened, Wanzhang Xia was glowing with brilliance, reflecting on the entire refining room, which looked extremely mysterious.

"Bang"

After a period of dizziness, Mu Tianyi was transported to a wonderful world, surrounded by fierce red flames, and in the flames there was a strange tree growing in it.

Although it burns incessantly in the flames, it grows longer and stronger, and grows higher and higher.

In the midst of that strange forest, a platform with a dazzling glow like ice crystals appeared in front of Mu Tianyi's eyes.

There are many grooves and holes on this platform, Mu Tianyi glanced at it, and found that a line of small words suddenly flashed on this platform, "Tianpin Artifact Platform"

"It seems that this is just a place to refine ordinary superb weapons!"

The weapons of this world are the strongest in the holy products, and most of the others are mortal weapons, and there are also some superb weapons, and there are few spiritual weapons, and of course, there is a legendary weapon called a divine product, but no one has ever seen it.

And this Heavenly Artifact Bench is equivalent to the best weapon level.

As he continued to go deeper, Mu Tianyi felt that the temperature around him was slowly rising, and not far away, the flames had turned from red to yellow, and beads of sweat began to ooze from his forehead.

A transparent divine beast with a whole body on fire soared in the yellow flames, and it turned out to be the spirit body of the fire unicorn, but the spirit of the fire unicorn seemed to be unconscious.

Directly below the fire unicorn is also a platform with a spiritual artifact table written on it.

Mu Tianyi did not stop, and continued to stroll forward, he found that not only the intensity of the flames was increasing, but even the air resistance was also increasing, and every step he took at this moment was extremely difficult.

The flames had gradually turned blue, and a palpitating scorching heat enveloped Mu Tianyi, and he felt as if he wanted to

It was scorched.

But strangely, the eternal heart in the body began to move slightly, and the heavenly fire that had not been seen for a long time began to swim along its meridians.

Since he had endured the severe pain of the Heavenly Fire and the Black Mist Fire burning in his body before, although the pain was still abnormal at the moment, he had begun to gradually be able to endure it.

Not only that, Mu Tianyi was surprised to find that this blue flame seemed to be being absorbed and fused by the heavenly fire in his body.

In the sky, a transparent figure dragged a long blue flame, emitting bursts of phoenix roars, hovering in midair.

As the blue flame gradually entered Mu Tianyi's body and was fused by the heavenly fire, the figure of the blue phoenix bird seemed to be more transparent than before.

"You have to speed up, if you continue like this, I'm afraid you won't be able to go inside at all, and you'll have to turn back!" Mu Tian counted the time, and a trace of anxiety welled up in his heart.

He suddenly let out a low shout, and the spiritual power of his whole body surged out, and the Nether Sparrow stepped to the limit, running forward, only to find that nearly a stick of incense had passed, and he was still in the same place, but his spiritual power was about to be exhausted.

"Don't waste spiritual power, the space here is different from the outside world, spiritual power and divine souls are imprisoned, so those fire-based divine beasts will not attack people, and in the same way, you can't use spiritual power, as well as the power of divine souls. ”

The voice of the book spirit came from the depths of his mind.

"That means if you show up now, you won't be able to leave here?"

"Yes, any spirit or even an out-of-body person, as long as they appear in this space, they will be imprisoned. ”

"Hey, I see, if you didn't say it earlier, I wasted so much spiritual power in vain. Mu Tianyi sighed helplessly, withdrew his spiritual power, and complained.

"I also just remembered that this thing is quite ancient, why is it in Tao Hao......'s hands?

Halfway through speaking, the voice of the book spirit stopped abruptly.

"Could it be that what is he? Emperor Xuan, don't you just say half of it?" Mu Tianyi was hearing the critical moment, but there was no follow-up, this heart itched unbearably!

"Maybe he is a member of the Fire Spirit Clan, but now the whereabouts of the Fire Spirit Clan are a mystery, and no one knows where this Fire Spirit Clan's settlement is. ”

"Maybe you guessed it right, no wonder I think his spiritual power is a little strange, but the spiritual power contains the power of fire, but it is not like the ordinary fire attribute, it is more like the feeling of being integrated into the soul. ”

Mu Tianyi was already sweating profusely at this moment, and his steps were difficult, and every step seemed to be carrying a burden of 10,000 catties.

After calculating the time, nearly half an hour had passed, and Mu Tianyi's heart became more and more anxious, and his pace sped up a lot.

Eventually, the blue flames turned purple, and the scorching heat had reached the point of near-destroying everything.

However, the Heavenly Fire in his body was even more excited, and he began to greedily absorb the purple flame power.

A huge figure appeared in mid-air.

"Who is it? I feel a familiar smell!"

Ziyan's voice sounded in his head, his voice trembled, and he sounded very excited.

"Don't go out, if you go out, you'll be imprisoned here just like him. Shuling reminded lightly.

That huge figure turned out to be a giant dragon spirit body that was smaller than Zi Yan.

Ziyan let out a heaven-shattering dragon roar in the dragon ball, and the entire dragon ball trembled.

But outside of Dragon Ball, you can't hear a sound.

Despite this, the purple transparent figure in mid-air trembled suddenly, perhaps sensing the energy fluctuations of the Dragon Ball.

Immediately, he also let out a shocking dragon groan, and then flew down, prostrate at Mu Tianyi's feet, with a faint sadness in his eyes.

"See His Highness the Dragon King!"

The spirit body of the transparent purple dragon can actually speak, it seems that his cultivation is not low, at least above the Emperor Spirit Realm, he can only do it if he has refined his divine soul.

"How did you end up in this Fire God Refining Heavenly Furnace?" Although the words came from Mu Tian's mouth, they were also what Zi Yan wanted to know.

Although it was close at hand, Zi Yan could only feel the breath of his fellow clan through the Dragon Ball, which made him feel depressed.

Immediately, there was a scream in the Dragon Ball, and it was actually the black wind that had been silent for a long time.

"You, you, you evil dragon, you can't see your companions, and it's not me who harmed you, why are you angry with me!"

"This king is extremely unhappy now, and it just so happens that there is no one else to fight here, so I have to beat you!If you are not happy, you can go out! This king is merciful and lets you leave Dragon Ball~!" Zi Yan glanced at Hei Feng and snorted coldly.

"Don't, don't, I'll die if I go out, you see, you just hit the right cheek, or you even hit the left cheek!"

Then another scream came.

Zi Yan finally exhaled a long breath and sighed, "Fortunately, there is a punching bag, otherwise this king would have to die of depression!"

However, the things inside the Dragon Ball, Mu Tianyi and the others don't know.

When the purple dragon spirit body told the ins and outs, everyone knew that he actually entered voluntarily, before he came in, he had no body, although he was imprisoned for countless years, but the soul was preserved, so that his soul would not be scattered.

Hearing this, Ziyan's mood was also a little better.

Under the guidance of the purple dragon spirit body, they came to the platform, the purple flame here is no less than the heavenly dragon purple flame of the heavenly fire, as long as the broken sword is put into the platform, after repair, it can be made into a holy weapon.

When Mu Tian heard this, his heart fluttered for a while, but he found that this refining platform was not the final core, and it seemed that there was a more mysterious place in the deepest part of Tianlong Ziyan.

So he asked, "What is the core area of this Fire God Heaven Refining Furnace?"

"There, I advise you not to go, even if it is a dragon clan like ours with the Heavenly Dragon Purple Flame, we will be burned to death if we go in! The fire there, I have never seen before, I am afraid it is not the fire of the Extraordinary Realm. Zilong's transparent figure looked into the distance, showing a hint of fear.

"That is to say, where the legendary divine product can be refined?" Mu Tianyi's eyes lit up at this moment, and his heart was full of surprise.

"Whether I can refine a divine product, I don't know, but I can definitely burn you to ashes!"

"Hehe, if I didn't try it, I wouldn't give up!" looked at the time, more than half an hour had passed, and if I didn't set off, I was afraid that I would really not be able to get out.

Without saying a word, Mu Tianyi rushed towards the unknown area. After absorbing some of the blue and purple flames, he found that he could adjust to the temperature, and although it was scorching, it didn't burn him.

This strengthened his confidence to move forward.

As the purple flames faded, there was a blinding area of white.
