"Buzz~!" The spiritual power was submerged into the Ding along the magic trick, and the pale white light of the Qiankun Ding made a burst of chirps, and the spiritual fire in the Ding suddenly ignited, and began to calcinate against the jet-black iron essence, after refining, the texture of the iron essence was extremely pure, and the essence had become a spiritual material.

Seeing this scene, Nie Ding unhurriedly increased the output of spiritual power, the crimson spiritual fire instantly increased, and the iron spirit was invincible and let out bursts of wailing, and the black light released became weaker and weaker, and he was defeated in a moment.

The black iron essence gradually turned red and soft, and finally turned into a red liquid state. Seeing that the fire was almost the same, Nie Bao's speed of pinching the magic technique changed, getting faster and faster, and his spiritual power suddenly turned into a blade, slashing at the liquid iron essence, dividing about one-tenth of the amount.

At this time, Qiankun Ding suddenly released a pale white Qiankun mana, constantly refining one-tenth of the iron essence, it was under the refinement of mana, the shape gradually lengthened and thinned, the tip of the head and the tail were thick, turning into a long cone with a ruler length and the thickness of a small finger, and this sharp cone was formed.

Nie Bao suddenly became nervous, the most critical moment came, he didn't dare to hesitate, the magic suddenly changed, the spiritual power did not enter the cone, and began to carve a complex array forbidden, this kind of formation forbidden, is the cultivator's comprehension of the laws of heaven and earth, the formation of astronomy, a single astronomy is a rune, complex astronomy is combined together, the formation of a formation is the formation of the forbidden method, carved into the magic weapon made of specific materials, it is the magic weapon, if the cultivation of the magic and the magic weapon formation prohibition does not conflict, with mana to cultivate the magic weapon, and then continue to add more precious materials, If you improve the essence of the magic weapon, it is possible to upgrade to a magic weapon, and of course, if the magic recipe and materials are advanced enough, it may also directly become a magic weapon. Only the innate spirit treasure cannot be refined, and only the innate supernatural power of the Qiankun Ding to the treasure level can be returned to the innate after tomorrow, and the unique laws can be generated in the spirit treasure and refined into the innate spirit treasure.

After becoming a magic weapon, it can be collected in the body, and it can be used to promote each other with the magic formula, and it may become a spiritual treasure, although this probability is very small and it takes a long time, but it is also the easiest way.

But these are too far away, now Nie Bao is even the most basic level of magic refining is very difficult, time has passed little by little, Nie Bao's spiritual power has been consumed about half, the formation ban finally successfully carved into the cone, the pale white mana, then injected into it, the formation ban was activated, and this awl is integrated into one, and then there is no distinction between each other, at this time, the awl suddenly became a black light, and then the light was boundless, becoming a one-foot-long awl with a small finger thick, flashing with a faint black light.

Nie Bao slowly withdrew his spiritual power, the white light suddenly flashed, and he disappeared into the body of Qiankun Ding in his sea of knowledge, the body of Qiankun Ding was rusty and full of cracks, after receiving the white light projection, the rust and cracks became less, and the elegant and elegant Qiankun mana fluctuated and rose, this kind of mana was very advanced, and it was unpredictable as soon as it appeared, full of deterrence, and it flowed out of the sea of knowledge from the ding, and traveled along the meridians of Nie Bao's body.

As soon as this mana appeared, it was swift and strong like **, frantically crashing into the acupoint, only listening to the muffled sound of fluttering, endless mana continued to consume, and constantly gushing out from the ding, breaking through the acupuncture points of the whole body, wandering around to temper the body, and expelling the impurities of the body, Nie Bao felt that his body was as painful as tearing, sweating profusely, but he still gritted his teeth and insisted, just like that, it was getting stronger and stronger, and gradually reached the physical strength that matched the level of Qi refining with the immortal cultivator.

This kind of intense pain comes and goes quickly, and the primary level of qi refining is not strong, so the strength of the physical body is very fast, and the pain disappears in a blink of an eye, and the feeling of coolness and comfort in the whole body gradually rises, Nie Bao snorted comfortably, and for the first time he felt that cultivation was so charming, not only immersed in it.

After stabilizing the realm, Nie Bao slowly collected his strength, and the mana in the meridians was as thin as light smoke, flowing slowly, and finally retracted into the Qiankun Ding of the Upper Dantian Knowing the Sea. He opened his eyes, and everything in the room suddenly brightened and enriched in his eyes, and all his senses became extremely sensitive. He moved his body, punched the air one after another, his fist cracked through the air, his strength doubled, and now it was as if he had taken off the burden of sinking, and he was relaxed, and a strange smell entered his nose, and he frowned, and now the room was full of this stench, and it was difficult to even breathe for a while.

Nie Bao looked down at his body, now he was covered with black impurities, like a thin layer of black mud, which was very uncomfortable on his body, he hurriedly opened the window to let the air circulate in the room, and then the smell faded, but when he saw the clothes on the bed, all of them could not be used, and the smell on it might not be washed off again.

Nie Bao threw them all away with a look of disgust, and he couldn't use them anyway, and then he didn't care about the dirt on his body, so he took out the magic weapon in the Qiankun Ding with a proud face, this is the first magic weapon he refined himself, the meaning can be described as extraordinary, I saw that this long cone was black all over, carved with a mysterious greyhound pattern from beginning to end, and there were dots of starlight shining on it, which was extremely beautiful.

He caressed this black dog nail lovingly, although the name of this magic weapon is not good, but it is a genuine primary magic weapon, and it is very famous in the world of cultivating immortals, it is a relatively common magic weapon, the genuine version is made of Xuanyin cold iron mixed with black spirit dog blood, specializing in the evil ghosts, if nailed to the body, there is a magic power of continuous damage.

But in this world, he hasn't seen any ghost things, so it's completely unnecessary to add black spirit dog blood or anything, and he can't get black spirit dog blood, so from the refining method, he removed the black spirit dog blood, the characteristic of overcoming yin evil, Xuanyin cold iron replaced with iron essence, retaining the remaining characteristics of the magic weapon, so that the difficulty of refining has also decreased, although the power has decreased, but the ability to restrain yin evil is not a pity.

Nie Bao injected mana into it, called the spiritual power to try to drive the magic weapon, in the end it was refined by himself, as soon as the spiritual power entered the black dog nail, he immediately got a response, only to see the black dog nail first shook a few times, and then slowly floated up, bumping and flying back and forth in the house, as Nie Bao's manipulation became more and more proficient, the black dog nailed in the house flew faster and faster, but did not touch anything, it looked very smart.

After the test was completed, Nie Bao suddenly increased the output of mana, and the spiritual power touched the forbidden array in it, and the black dog nail suddenly shook, stopped in mid-air, and began to shrink rapidly, becoming the size of an embroidery needle, and continued to fly back and forth in the house, and the flight trajectory became extremely hidden for a while, looming, sometimes large and sometimes small, and the speed was no different from the flight of pistol bullets for a while.
