"This kind of cold that has accumulated over the years can never be caused by normal circumstances." glanced at Mu Yuxi, and continued with some hesitation. "So near this piece of dark iron, there must be some extremely cold core of the dark iron vein or something. If nothing surprises me, it's likely to be the same material as the Meteorite. ”

"Then don't think about it." Seeing that innocence was mentioned, Mu Yuxi also shook her head helplessly. "Not to mention how difficult it is to dive into the deep sea that has not yet reached a low level of at least a kilometer, just looking for something that sinks into the water without any reference coordinates is even more unreliable than carving a boat and seeking a sword."

"Also, this level of material is definitely not so easy to appear." After sighing for a moment, he looked at Mu Yuxi innocently and continued. "Let's talk about this piece of dark iron first, since there is no way to melt it here, then we have to melt it in another place and then build it."

"Where are you going?" Knowing that this piece of dark iron could not be melted and could not be built, Mu Yuxi also asked a little helplessly.

"Under Kunlun Mountain, on the Xuanhuo Palace." And the answer given by innocence made Mu Yuxi frown a little inexplicably.

"Wait, even if it's a magma environment, it can't provide much higher temperature than this molten iron furnace, right?" Pointing to the bright blazing white flames overflowing from the furnace on the side, Mu Yuxi asked directly about innocence.

"If only the high temperature could melt this piece of dark iron, then this piece of dark iron would have been refined by me a long time ago." sighed helplessly, and said with a helpless face. "The key is the cold air in this piece of dark iron! At present, only the power of the fire spirit in the magma under the Xuanhuo Palace can dissolve this cold qi. ”

"That's right." Mu Yuxi, who nodded a little clearly, and then thought of something, suddenly asked. "Wait, if it's taken from the internal force of the Xuanhuo Palace's underground, is it okay?"

"This?" Looking at the scorching strength in Mu Yuxi's palm, the innocence in his eyes full of surprise finally nodded. "You can try."

The inner breath of the Burning Sun Heart Sutra, the initial cultivation is the scorching aura around the channeling area, and finally igniting an inextinguishable heart fire in the meridians can be regarded as successful cultivation.

Since Mu Yuxi's Burning Sun Heart Sutra was originally cultivated in the Xuanhuo Palace, there is no reason why the internal breath of the Burning Sun Heart Sutra in Mu Yuxi's body would be inferior to the conditions of the underground magma environment of the Xuanhuo Palace, right?

So under the innocent watchful gaze of the side, Mu Yuxi, who was operating the inner breath of the Burning Sun Heart Sutra in his body, immediately poured all the internal breath of the Burning Sun Heart Sutra that could be mobilized in his body into the dark iron block in Mu Yuxi's hand.

"It's now!" Suddenly perceiving the black iron block in Mu Yuxi's hand, after being really suppressed by Mu Yuxi's internal breath, Innocence immediately pointed to the open furnace and shouted to Mu Yuxi.

Without hesitation, Mu Yuxi quickly threw the dark iron in his hand into the furnace that opened the entrance on the side, and then gave way to let the innocence begin to smelt.

Although Mu Yuxi, who was watching from afar, couldn't see the situation in the furnace.

But a moment later, the red molten iron flowing out of the open furnace was clearly announcing the successful melting of the black iron block.

Seeing this, Innocence immediately poured the molten iron mixed with the auxiliary materials directly into the mold that had been prepared on the side, and let the hot molten iron fill all the space in the abrasive.

Whoa!

"Come here, pour in your strength!"

At the same time that the cooling water vapor instantly filled the studio, the call of innocence also immediately sounded in Mu Yuxi's ears.

Without much hesitation, Mu Yuxi immediately took a few steps forward, and then came to the position where innocence got out of the way.

"Hurry up, the time is limited!" And when Mu Yuxi looked at the two crimson sword bodies in a daze, Mu Yuxi's words of pure urging made Mu Yuxi helplessly squeeze her hands on the hilt of the hot sword body.

Whoa.

Under the impact of the large amount of internal breath of the I Ching Forging Bone Chapter infused into Mu Yuxi's body, not only did Mu Yuxi's palm not suffer a trace of burns, but even the originally red sword body quickly turned into pitch black at a speed visible to the naked eye.

Buzz.

As Mu Yuxi once again poured into the inner breath of the Burning Sun Heart Sutra, which triggered a mixed explosion of internal breath, the two sword bodies in Mu Yuxi's hands were also making a disturbing vibration sound.

"Oxfork." I snatched the two sword bodies from Mu Yuxi's hands and put them back into the furnace without forgetting to admire the innocence.

As Innocence burned it red again and again, and then cooled by Mu Yuxi's internal breath, the sword bodies of the two long swords were finally forged in Innocent's hands.

"Here, quench one last time." He burned the two sword bodies with incomparably red innocence, and handed the sword bodies to Mu Yuxi and said.

"Not the inner breath, with your blood!" Just when Mu Yuxi once again planned to repeat the scene of quenching and cooling down the inner breath, Mu Yuxi's innocent words made Mu Yuxi slightly stunned.

"Wait, when it comes to blood sacrifices, shouldn't we use the blood of the builder?" Thinking of the story of the cadre Mo Ye, Mu Yuxi's eyes immediately began to look at the innocent body, as if he was studying where to start.

"This is your sword, you can do it yourself." was not afraid of Mu Yuxi's innocence of threatening eyes at all, and placed the two sword bodies horizontally in front of Mu Yuxi and let them choose. "Don't forget you're a builder too!"

The corners of his mouth cut disdainfully, Mu Yuxi directly stretched out his right arm, and then slashed his wrist with a knife, so that the blood flowing out of his wrist poured on the red sword body.

Whoa.

As Mu Yuxi's blood emitted a series of violent gasification sounds on the hot sword body, when the two sword bodies were finally quenched for the last time when Mu Yuxi's qi and blood value was only one-fifth.

With a flash of golden light, under Mu Yuxi's surprised and innocent gaze, the creation of the two sword bodies finally announced their final completion.

"Impossible, right? Could it be that there is a very small probability of leapfrogging the upgrade?! After finally reacting from the shock of the flash of golden light just now, Chun Qing hurriedly looked at the two sword bodies in Mu Yuxi's hands and asked. Look at the attributes, look at the attributes! ”

"Except for the name of the completed sword body, there are no other attributes at all." Mu Yuxi, who opened the system bar, looked at it, and suddenly asked with some excitement. "It's just in gold font, is it really a withdrawal?!"

"Damn, what kind of shit luck is this!"
