Although the two melted liquid materials were fused together, they were not so pure, and they needed to be re-refined with earth and fire.

One day half a month later, sitting in front of the huge smelting furnace and meditating, his eyes were fixed, and he opened the smelting furnace to get out a cloud of liquid inside, suspended not far from his body.

Shen Luo opened his mouth slightly, and spit out a golden round pill of inches in size, which was the golden pill in Shen Luo's dantian, and there was a faint thunder and lightning aura on the appearance of the purple golden pill.

The purple golden pill appeared and coiled on the top of Shen Luo's head, and under Shen Luo's urging, the purple golden pill spun rapidly, and at the same time, a purple flame erupted from the golden golden pill.

This purple flame is the innate true fire in the innate stimulation of the dantian, and Shen Luo wants to use the innate true fire to better integrate many materials in the liquefaction, and burn the impurities in it by the way.

The purple flame enveloped the liquid, and the next burning was seven days under the urging of Shen Luo's mana.

Seven days later, Shen Luo put away the purple golden pill, took out a mana recovery pill and swallowed it.

Even though his mana was far superior to that of a monk of the same level, he couldn't resist continuously urging his mana for seven days, and used the purple golden pill to spray out innate true fire.

Looking at the liquid that had been refined by the innate true fire in front of him, Shen Luo's big hand void lightly grabbed and pulled, and a mini small sword cone appeared.

Immediately afterwards, Shen Luo's hands changed and continued to pinch the magic trick, and he smashed the spiritual lights of different colors into the small sword.

Injected with the aura of Shen Luo's magic technique, the small sword also gradually solidified slowly, and played the last magic trick in Shen Luo, pouring the prepared heavenly spirit liquid on the cured small sword.

The sound of "zi, zi" kept ringing, and at the same time, the purple aura around the small sword flashed and flashed.

When the purple spiritual light on the small sword dissipated, Shen Luo manipulated the small sword to be inserted into the heavenly spirit liquid refined by the gourd, so that the whole body of the small sword was covered by the heavenly spirit liquid, and the sword body of the small sword emitted spiritual light again, and absorbed and ate the heavenly spirit liquid little by little.

Shen Luo was not idle on the side, he kept chanting obscure spells in his mouth, and his hands accompanied the spells to pinch out one formula after another, in order of order, and engraved one formula after another on the sword.

After absorbing the heavenly spirit liquid, Shen Luo also completed the engraving of the sword body, he held the small sword that had just been refined in one hand, which took him a lot of effort to refine, and he couldn't put it down and played with the small sword in his hand.

"This sword is refined with five element attribute materials, but it is my natal magic weapon, so let's call it the Mixed Yuan Sword."

Looking at the transparent luster of the Mixed Yuan Sword exuding from the sword, Shen Luo crossed his spiritual power into the Mixed Yuan Sword, and the Mixed Yuan Sword suddenly grew into a cold light long sword.

"What a good sword!"

Weighing the Mixed Yuan Sword in his hand, Shen Luo's mind suddenly moved, he just felt that this Mixed Yuan Sword actually contained wisps of thunder and lightning.

"It's strange that I didn't have a thunder attribute material when I was refining, why did my Mixed Yuan Sword have a thunder and lightning aura."

Holding the mixed yuan sword in his hand, Shen Luo was dumbfounded, and he didn't know for a while, so he didn't know what was going on.

"Could it be that I used the Jindan True Fire to refine the reason?" Shen Luo suddenly thought.

It must be known that when he condensed the Jindan before, the Jindan contained the breath of thunder and lightning, and now he used the Jindan Innate Fire to refine things, thinking that it might be the case.

He flicked the fingers of his hand on the Mixed Yuan Sword, and under the urging of his mana, a faint white gauze-like arc immediately appeared on the body of the Mixed Yuan Sword.

"The five elements plus the breath of thunder and lightning are not bad."
