The tenacity of the Nine Nether Iron exceeded Yuan Ming's expectations, and the refining process was extremely long, but fortunately, Yuan Ming had already made sufficient preparations, and even prepared a lot of medium-grade spirit stones, which were used to fill the spiritual power consumption of releasing the Danhuo.

Ten days later, the Dark Iron Gourd was finally completely melted, and all the impurities in it were dispersed by Yuan Ming, leaving only a fist-sized mass of pitch-black iron pulp.

In addition to the dark iron slurry water, the jade fragment in the gourd is still floating, after this long period of burning Danhuo, even the dark iron has melted into water, but the jade fragment has not changed, and the luster on the surface has even become brighter.

Yuan Pin opened the refining furnace in the air, took out the jade fragments, and put them aside for the time being, then raised his hand a little more, and sent the Soul Destroying Sword that was placed aside into the refining furnace.

Although the number of runes that a magic weapon can withstand is determined by the main material of the magic weapon, it also has a great deal to do with its quantity.

Although the Soul Slayer Sword is made of Nine Nether Iron as the main material, there are not too many Nine Nether Iron in the sword body, and it may not be able to withstand seven runes.

There are many methods of ascension and refining that he learned through black incense, and there is a unique secret technique called "Homogeneous Compression Method".

This method is to mix the same spiritual materials into the things that are refined, and compress and condense them with special methods, so as to increase the power of the magic weapon in disguise.

This secret technique is quite easy to use, and it can increase the power of the magic weapon without destroying the original runes.

Ten days later.

Yuan Ming melted the form of the Soul Slayer Sword, and then merged it with the previous Dark Iron Slurry Water and began to compress and condense.

And this step takes far more time than Yuan Ming imagined!

It took him nearly half a year to complete it.

After condensing, the Soul Slayer Sword was slightly larger than before, and its color became deeper and deeper. It also feels much heavier in my hand than before.

Yuan Ming was re-tempering the Soul Destroying Sword, and did not immediately start the next step of refining, but sat cross-legged on the lotus platform and rested silently.

In the past six months, he has only used the Divine Consciousness Auxiliary Refinery, and he has not shown much fatigue.

It's just that after a long time of urging the Danhuo, the exhaustion accumulated on the body is difficult to eliminate, so even if his spirit is good, he has to stop and rest for a while.

Yuan Ming felt more and more weak in his body, and when he was resting, he couldn't help but feel a little envious of King Kong.

If he can refine his physical body to the strength of his innate body, his strength will be greatly improved.

Yuan Ming thought about it, and suddenly remembered that when he was in Southern Xinjiang, he had sold a body cultivator named Long Jing, and he had not been able to use black incense to possess this person before, so he gradually forgot about it, and when he thought about it, he didn't know if he could possess this person after stepping into the Jiedan, and take the opportunity to learn a method of refining the body.

Of course, now that he is a dual cultivator of the Law and Soul, he has invested several times more in terms of energy and time, if it weren't for the continuous supply of pills and willpower, coupled with the obedience of top exercises such as the Nine Yuan Jue in cultivation, he would not have been able to reach the point where he is now.

In terms of physical cultivation, I don't have too obvious advantages now, if I don't have a special opportunity, I am afraid that if I blindly practice, I am afraid that I may not be able to get a good harvest if I invest a lot of energy, and I will occupy my cultivation time in other aspects in vain, and the gains will outweigh the losses.

Half a month later, Yuan Ming's body completely recovered, and after adjusting his state again, he began refining again.

The next step is to carve the runes.

Although he had already entered the stage of knotting, due to the incomparably hard iron of the underworld, not to mention that it had just been compressed and tempered, Yuan Ming at this time still had to take out the high-grade carving knife he had purchased, and carved the runes on the soul destroying sword one by one.

The first thing he engraved was the rune with the curse effect.

The complexity of this rune far exceeded all the runes that Yuan Ming had mastered, even though he was confident that he had already practiced sufficiently, and the strength of his divine soul was far greater than before, he still didn't dare to be careless when it came to the actual portrayal.

But just when his carving knife dropped the first stroke, an accident happened.

As the carving knife slashed, a shallow one more appeared on the Soul Slayer Sword

Shallow dark marks, but at the same time, Yuan Ming saw that the body of the Soul Exterminating Sword was shining in vain, and an inexplicable suction force appeared on the dark marks, following the carving knife, spreading into Yuan Ming's body.

Yuan Ming only felt that the mana in his body was being pulled into the dark mark, and the wisps of mana filled the line that had just been carved little by little, but the dark mark did not seem to be satisfied, and the suction on it was a flurry.

The inexplicable power rushed towards Yuan Ming's sea of knowledge, attracting the soul power in it, and also surging towards the dark mark that had just been depicted.

Seeing this situation, Yuan Ming was taken aback, but the depiction of runes must be completed from the beginning, since he has already fallen the first stroke, he must finish the subsequent lines in one go, otherwise everything will be wasted.

He didn't hesitate, and after taking a deep breath, he forcibly stabilized his mind and continued to portray.

Every time the stroke falls, the suction on the soul destroying sword will increase a little, which makes Yuan Ming's portrayal more and more difficult, just less than a fifth of the carving, he feels as if there are thousands of mountains in front of the carving knife, a simple vertical line, it takes a lot of time to carve.

At the same time, on the Soul Exterminating Sword, on the lines that had already been carved, a faint spiritual light lit up little by little, and the speed was always a little slower than Yuan Ming's carving knife.

Until now, Yuan Ming had realized that the rune he was going to depict was extraordinary, and its spiritual rhyme was even enough to break through the convention, mixing the two processes that should have been separated, the carving talisman and the spirit infusion.

However, whether it is a magic weapon or a magic weapon, in the step of instilling spirits, it is necessary to fill in unimaginable spiritual power, and ordinary refiners choose to put spirit stones into the refining furnace when refining, so as to provide the required spiritual power.

However, Yuan Ming could only use his own mana, and even soul power, to complete this very expensive step of instilling souls.

Although he was sitting on the lotus platform at this time, his divine soul power had increased greatly, and at the same time, he also had the desire power to continuously replenish his soul power, but in terms of mana, he still gradually felt a sense of withering gradually emerging from his body.

Yuan Ming didn't dare to stop, so he could only temporarily draw a trace of mana, summon the spirit stone he had prepared before to his side, and continue to absorb the spiritual power in it to fill the spiritual infusion needs.

Gradually, the situation eased.

Yuan Ming's carving knife carved the rune slowly but steadily, and his mana and soul power were like a trickle, filling the rune vacancy unhurriedly, and everything was going in a smooth direction until seven days later.

On the Soul Slayer Sword, there were only a few lines left of the "curse" rune to form, but the sword body suddenly shook at this time, and the amplitude was small at first, but as the rune depiction advanced, the tremor became larger and larger to the point where Yuan Ming had to forcibly hold it with his hand.

Faced with this situation, Yuan Ming seemed expressionless, but there was a little more anxiety in his heart.

With his current refining level, he could naturally see at a glance that this was a sign that the Soul Exterminating Sword could not withstand the rune branding, but he had obviously refined and compressed the Soul Exterminating Sword before, and if it was only the fifth rune, it was impossible for him to be unable to withstand it no matter what.

The problem is just with the rune.

Yuan Ming had imagined that the Soul Exterminating Sword might not be able to fully withstand the three supernatural runes, but he never thought that the Soul Exterminating Sword that had been refined and compressed would not be able to withstand even two of them.

However, things have come to this point, and Yuan Ming has long had no room for regret, so he can only grit his teeth and hold the carving knife painting tightly, while pouring the mana and soul power in his body on the sword body, trying to speed up the speed of carving and instilling spirits.

Time passed little by little, and soon another day passed.

Under Yuan Ming's forcible suppression, the shaking of the Soul Exterminating Sword was always restrained within the scope of not affecting the inscription, but its sword body was already covered with cracks, and it seemed that it might fall apart and shatter at any time.

Yuan Ming's carving knife is the distance between the completion of the carving and the completion of the engraving, which is almost invisible, but it is like the sky, separating success and failure.

At this time, Yuan Ming's eyes were already red, his forehead was even more bruised, and the hand holding the carving knife was white, obviously he had exhausted all his strength, ready to make a desperate bet.

Suddenly, Yuan Ming felt the carving knife in his hand loosen

, The power that had just stopped him turned into a breeze and dissipated in an instant, and Yuan Ming's heart jumped and he hurriedly raised the carving knife to prevent it from leaving extra scratches.

But at this moment, on the body of the sword full of cracks, the already flat suction power skyrocketed again, and Yuan Ming pressed the left hand of the Soul Slayer Sword as if it was glued to the sword, no matter how hard he tried, he couldn't pull it down.

But this time, the Soul Exterminating Sword no longer absorbed his mana, but devoured his soul power like a giant whale, and Yuan Ming's soul power in the sea quickly withered, but in the next moment, it was filled with a frenzied influx of pure wish power.

With such an inhalation and release, Yuan Ming's soul was even affected, and he felt a wave of dizziness and tingling sensation that appeared from time to time like waves.

He felt like a pipe that transported soul power, sandwiched between the Soul Slayer Sword and Liantai.

I don't know how long it took, the Soul Slayer Sword seemed to have swallowed enough soul power, and gradually slowed down the suction, and Yuan Ming was finally able to withdraw his hand from the sword.

While he breathed a sigh of relief, he looked down, only to see that on the Soul Exterminating Sword, all the cracks that had appeared during the previous refining had been eliminated, and they were replaced by smooth purple lines, intertwined with each other, like a swimming dragon attached to the Soul Exterminating Sword, which was extraordinary.

It worked! The five runes on the sword's body were all shining at this time, but the last rune that represented the "curse" was passing rapidly, as if it would disappear completely in the next moment.

Yuan Ming's heart jumped, and he hurriedly took out the Soul Exterminating Sword, immediately bit the tip of his tongue, spurted out a mouthful of essence blood on the sword's body, and then wrapped the Soul Exterminating Sword with Danhuo again, fusing his own essence blood with it.

Gradually, Yuan Ming felt that he had developed a vague connection with the Soul Exterminating Sword, and then without hesitation, he cast a magic trick, sucked the Soul Exterminating Sword into his body, and used the Dan Fire in his body to wrap it in warmth.
