The moment Yun Mo's divine mind touched the 'Blue Lotus Pure World Fire', an extremely hot aura burst out instantly, and immediately a visible cyan flame completely enveloped Yun Mo.

Even if Yun Mo was a third-layer cultivator of Yuanying at the moment, he couldn't resist it under this scorching flame, but in an instant, his armor was swept away by the flames, revealing the skin underneath.

However, at this time, the advantage of the middle stage of Yun Mo's royal body was revealed, no matter how powerful this flame was, it only melted Yun Mo's skin and flesh.

Seeing this, Yun Mo's heart that was hanging at the beginning was also completely relaxed, and those melted skins, he only needed to run the 'Xuanzhen Transformation Immortal Technique' a little to easily recover.

From this point of view, the 'Qinglian Pure World Fire' in front of him is at his disposal.

While the 'Xuanzhen Transformation Immortal Technique' was running, Yun Mo's stagnant refining body also woke up again, and the flames could hurt his flesh and blood, which showed that it was still helpful to his refining body.

However, Yun Mo didn't pay attention to refining his body at this time, and his entire mind was immersed in refining the 'Blue Lotus Pure World Fire'.

As time passed, Yun Mo's refining of the 'Blue Lotus Pure World Fire' became deeper and deeper, and the latter's cyan flame gradually faded.

Half a month later, all the flames on the top of the mountain disappeared, no, not only on the top of the mountain, but also on the peak.

The incomparably terrifying scorching breath between heaven and earth also completely dissipated, and the breeze blew, bringing a slight sense of coolness to this mountain peak.

Yun Mo stood on the top of the mountain, raised his right hand slightly, looking at the cyan flame beating in his palm, the joy on Yun Mo's face could no longer be suppressed.

"Hahahaha......"

Yun Mo looked up to the sky and roared, he finally had a flame, and it was also the seventh 'Blue Lotus Pure World Fire' among the thirty-six heavenly fires, with this flame, he could not only improve the Dan Dao cultivation that had been stagnant for a long time, but he could finally start refining weapons.

Thinking of the refining weapon, Yun Mo directly sat cross-legged on the ground.

As early as before, when Yun Mo obtained the knife embryo refined by the Heavenly Star Quicksand, he wanted to refine his own natal magic weapon.

However, at that time, his refining weapon was only in the theoretical stage, and he didn't have a flame that could be used for smelting, so it was delayed, so that from the time the Stygian Flame Knife was shattered, until now, he didn't have a magic weapon to take advantage of.

Now that he has the flames, he can naturally start refining weapons.

However, Yun Mo didn't take out the knife embryo for immediate refining at the first time, but instead took out a few fifth-level refining materials, which he needed to use to test the water first to test his refining knowledge and theory.

Yun Mo sacrificed the 'Blue Lotus Pure World Fire', and integrated those materials into the flames one by one, and the fifth-level materials naturally couldn't stop the scorching and smelting of the 'Blue Lotus Pure World Fire', and they were melted in just a moment, and they were immediately put together.

About an hour passed, and a complete long knife shape appeared in the flames, and with Yun Mo's gesture, the flames wrapped the long knife inside and carried out the final tempering.

Bite!

With a clear sound, a long knife three feet long and four inches wide appeared in Yun Mo's hand.

"I didn't expect that I would refine a long knife with a top-grade magic weapon for the first time I refined!"

Yun Mo looked at the long knife in his hand that was bubbling with cold light, and he was very satisfied in his heart.

You can refine a top-grade magic weapon with a fifth-level material, so in this case, when you can smelt the blade embryo, you should be able to get the best magic weapon in the end.

Yun Mo didn't expect to be able to go directly to the spirit weapon, he still had a clear understanding of his refining level.

Soon, Yun Mo took out the knife embryo and directly threw it in the 'Qinglian Pure World Fire' and began to burn and smelt.

Even if this blade embryo was refined by the ninth-level material Heavenly Star Quicksand, under the fourth-level Heavenly Fire, it only lasted for a moment before it was completely smelted.

After smelting, the shape of the knife tool was completely lost, and it directly returned to its most primitive state, which was exactly what Yun Mo needed.

It stands to reason that Yun Mo's best choice is actually to further smelt the knife embryo and turn it into a knife body, after all, the so-called knife embryo is already a semi-finished magic weapon, as long as the knife body is turned out, it is already considered to be refined, at least it will be a superb magic weapon, or even a long knife of a spiritual weapon!

It can be said that it is done in one step, and it will save a lot of time and energy.

However, Yun Mo did not choose to do this, but chose a thankless way, melting the knife embryo and returning everything to its primitiveness.

And the reason why Yun Mo did this was that when he was smelting the knife embryo, he found that the first prohibition on the knife embryo had been refined, and it was very likely that it was that Xu Xinghe.

In this case, when this knife embryo was finally completely formed, it could not be 100% fused with his aura, even if Yun Mo removed the forbidden that had been refined.

Second, that is, Yun Mo does not like the shape and length of the knife embryo, although it can be changed when it is finally formed, but the change will not be very large, and at the same time, Yun Mo will add the Burning Sky Flame Gold in the end.

Another half a day passed, and a brand-new knife embryo appeared in the 'Qinglian Pure World Fire', and just when this knife embryo appeared, Yun Mo decisively took out the Burning Sky Flame Gold and threw it on it.

"Bang!"

As soon as the Burning Sky Flame King Kong landed on the 'Blue Lotus Pure World Fire', it exploded instantly, turning into a sky of golden powder and blending into the quicksand of the Heavenly Star.

At this moment, the starry quicksand was also trembling, and in a blur, Yun Mo seemed to see an incomparably brilliant starry sky, circling endlessly in front of him.

And after the starry sky, Yun Mo saw an inwardly rotating crimson sky dome again!

The crimson sky dome quickly intertwined with the brilliant starry sky, and then dissipated in an instant, leaving no trace behind.

Yun Mo was only shocked by this scene for a moment, and then he put his mind into the refining weapon again.

At this time, the vague knife embryo was also gradually evolving and taking shape under the drive of Yun Mo.

At the same time, an extremely strong sword aura also gradually emerged in the space.

At first, it was just a little bit, and by the end, it was already filling the entire space.

The violent sword qi struck, and Yun Mo was almost shocked back by this sword qi, but fortunately, he stabilized in the end, otherwise this refining weapon would have failed.

And once he really fails, Yun Mo is afraid that his heart will drip blood.

Whether it was the Heavenly Star Quicksand or the Burning Sky Flame Gold, they were all peerless treasures that could be encountered but not sought, if they were really refined and scrapped by him, Yun Mo was not sure if he would have the opportunity to obtain these two materials in his life.

The knife qi is getting stronger and stronger, and the knife embryo is becoming more and more blurred, this ambiguity does not mean that the knife embryo is going to disappear, but it is evolving towards the last knife weapon!

"Boom!"

A muffled sound came, and the violent sword qi that was originally filled with space instantly dissipated, and the knife weapon refined by Yun Mo was also completely finalized, quietly suspended in the 'Qinglian Pure World Fire'.

Yun Mo didn't remove the flames immediately, but instead squirted a mouthful of essence blood and landed on the knife.

The essence blood fell on the long knife, and a feeling of connecting the heart and blood surged in the bottom of his heart, and Yun Mo's divine thoughts fell on the knife, and it only instantly refined the eighteen prohibitions above.

"Choke!"

With the withdrawal of the 'Blue Lotus Pure World Fire', a clear sound sounded, and the overall blade of the knife was four feet long and five inches wide, with faint lines like a galaxy on the back of the knife, and on the blade, there was a red line from shallow to deep, spreading all the way to the end of the hilt.

"Hahaha......"

Looking at the knife in front of him, Yun Mo couldn't help laughing anymore.

At this moment, the natal magic weapon that belonged to him Yun Mo was finally refined!
