Shen Luo bit the tip of his tongue and spurted out a mouthful of essence blood.

With a soft "bang", the essence blood burst open, turning into a cloud of blood mist and enveloping the dark red sword inside.

He pinched the trick with both hands, and after the blood mist swirled around the small sword, it all merged into it and disappeared.

Then Shen Luo's ten fingers opened again, and ten blue lights shot out from his fingertips, turning into ten sharp blue filaments, taking advantage of the fact that the small sword was not completely solidified, and quickly engraved runes on the body of the sword.

The runes spread out, faintly forming a miniature circle.

A quarter of an hour later, he let out a long breath and dissipated the blue filaments of light from his fingertips.

The dark red sword has been completely solidified, but the magic circle on it has also been burned.

However, the refining of the sword embryo was not over yet, Shen Luo picked up a small white powder next to him, sprinkled it on the dark red sword, and then threw it into the flame of the casting furnace and roasted it.

The white powder was quickly incinerated, like a grain of salt meeting water, and gradually merged into the small sword.

He immediately picked up another material, carefully followed the method recorded in the Pure Yang Sword Codex, and continued to refine it into the sword embryo.

This refining was a day and a night, and as all the materials were integrated into the sword embryo, its appearance also changed, the color changed to light red, and some of the originally slightly rough parts of the sword body also became delicate.

The entire sword was sharp, and the whole body exuded a fierce aura.

Shen Luo didn't stop, took a deep breath, and pinched the trick with one hand.

The Pure Yang Sword Embryo flew out with a "whoosh" and landed in the center of the ground magic circle, levitating there.

He pinched the trick again, and the magic circle on the ground suddenly made a buzzing sound, and a powerful spiritual power fluctuation erupted, and then a large red light flew out from the magic circle.

These red rays are layered on top of each other and intertwine with each other to form a huge red lotus flower.

The pure yang sword embryo suspended in the center of the magic circle also suddenly lit up, and a large area of crystal red light bloomed from above, and it quickly rotated around the sword embryo, forming a red vortex.

Shen Luo didn't know the specific effect of the magic circle in advance, and when he saw the scene in front of him, he was slightly surprised.

However, he quickly calmed down, waved his hand and took out the white jade box, put it in the magic circle, pinched and condensed two palms, opened the stone box in the air, and at the same time rushed into the void, a blue light flew out and merged into the stone box.

After discovering that the stone box could collect the red lotus karmic fire, he also used the Nine-Nine Pass Treasure Recipe to try to refine this thing during this time, but the white stone box was different from the talisman magic weapon, although it contained some forbidden power inside, even the Nine-Nine Pass Treasure Recipe could not be refined.

However, this attempt was not completely fruitless, and Shen Luo was now able to pry a little bit of the forbidden power in the stone box.

When the blue light merges into the stone box, a faint white light glows on the stone box.

The red lotus karmic fire the size of a human head flew out from inside, and it actually fled outside, as if it contained spiritual wisdom.

Shen Luo hurriedly recited the incantation, urging the magic circle, and the red light in front of the red lotus karmic fire condensed, forming a red light cover.

With a soft "bang", the red lotus hit the light mask and was ejected back.

The red lotus flower in the magic circle also slowly rotated at this moment, sending out a force of attraction, enveloping the red lotus karmic fire.

The red lotus karmic fire was covered by this force of attraction, although it was struggling, its strength was obviously not able to withstand the power of the magic circle, and it was slowly pulled to the top of the red lotus of the magic circle, and was imprisoned there by the power of the magic circle.

Shen Luo breathed a sigh of relief, and continued to pinch the trick to urge the formation, and at the same time, he opened his mouth and spit out, spewing out a stream of pure mana, which merged into the pure yang sword embryo.

The red crystal light emitted by the Pure Yang Sword Embryo immediately lit up, and the red vortex around it more than doubled.

"Snort" A few times sounded softly, and several red sword qi shot out from the whirlpool, flying upward, as fast as lightning, entangled the corner of the red lotus karmic fire, and slashed quickly.

There was a soft sound of "snort", and a fist-sized red lotus karmic fire was suddenly cut down.

Then those few red sword qi continued to entangle this red lotus karmic fire, pulling it into the whirlpool below.

Shen Luo's right hand urged the magic circle, and his left hand pointed at the pure yang sword embryo void, and the red vortex immediately flew and rotated, as if it was a big mouth, wanting to devour this red lotus karmic fire.

And the magic circle outside also ran rapidly, and an invisible force blessed into the red vortex, and the devouring power of the vortex power immediately increased greatly.

However, the Red Lotus Karmic Fire is a heavenly fire, which contains a strong spirituality, and as soon as it senses danger, it immediately struggles to resist it.

The reason why those sword qi red lights were able to cut off this red lotus karmic fire just now was all due to the swiftness of the sword qi, and now if you want to refine it into the sword embryo, you can only grind it with water and slowly refine it.

Time passed little by little, and half an hour passed in the blink of an eye.

At this time, Shen Luo's face turned pale, and there was not much mana left in his body, obviously urging the magic circle and refining the sword embryo at the same time to consume a lot of mana.

However, he had already prepared, took out a milky white pill and took it.

This medicine was obtained from Hu Yong's storage ring, and after taking it, a cold feeling immediately appeared in the dantian, and the consumed mana suddenly began to recover slowly.

But that small group of red lotus karmic fire was still suspended in the whirlpool, not refined, and it was quite immovable.

"The heavenly fire is really powerful, and even such a small group is so indestructible. Shen Luo sighed secretly, but he was not too surprised.

If it is so easy to refine, the Red Lotus Karma Fire will not be a Heavenly Fire.

Spiritual fire is born and raised, and it is not easy to refine, so the pure yang sword canon is fully prepared, and there is another method that uses the power of essence and blood to perform the art of blood sacrifice, urge the pure yang sword embryo array, and refine the spiritual fire.

Just performing this method will put a lot of burden on the body, and it will even deplete the original element.

But now he has no choice, there are not too many milky white pills, if he can't practice the pure yang sword embryo before he runs out, all his efforts will be in vain, although this method will damage his body a lot, he can't take care of it.

Shen Luo quickly made up his mind and silently used this method, his face was flushed with a layer of blood, and then he bit the tip of his tongue and opened his mouth to spit out.

A bloody light shot out like an arrow, merging into the pure yang sword embryo.

He then put his finger in his mouth and bit it, and then continued to pinch, and the blue spells continued to shoot, but each one was stained with a trace of blood.

With a soft sound of "boom", a layer of dazzling blood light appeared on the pure yang sword embryo, and then countless blood-colored runes sprung up like mushrooms after a rain, mixed in the whirlpool.

The whirlpool spun faster and whined, like the moans of an ancient demon god, and its power increased tenfold.

Not only that, the art of blood sacrifice seemed to be able to communicate with a powerful being in the underworld, and a fierce aura gushed out from the whirlpool, enveloping the red lotus karmic fire, and the spiritual impact contained in the red lotus karmic fire itself.

This small group of red lotus karmic fire suddenly rolled up, trying its best to resist, but under the double attack of the formation vortex and the blood sacrifice technique, it was still defeated after half an hour.
