After the fire snake appeared, it began to drill in and out of the hole of the refining furnace, so that the original half-red furnace began to gradually transform into red.

"Little Four, you go and use the formation to open the lid of the furnace!" Half a quarter of an hour later, Master Feizhen felt that the heat was almost over, turned to the apprentice next to him and ordered, and then said to Wan Qingping: "Wan Daoyou, wind and wood......"

"Master rest assured, it's already ready!" As he spoke, his sleeve robe shook, and a tray appeared in his hand, on which were neatly placed the wind-growing wood branches needed for refining treasures, no more, no less, thirty-six.

The old man nodded, didn't say anything more, and continued to look at the Heaven and Earth True Law Furnace with blazing eyes.

After a while, there was a wave of spiritual power above the crater, and a large area of black light was generated out of thin air, and the rolling black light fell on the furnace ding, revealing several huge runes, and then the runes quickly swam around the edge.

As time passed, the runes moved faster and faster, until they were difficult to catch with the naked eye, and the lid of the furnace let out a dull hum, as if pulled by some mysterious force, revealing a gap not yet large enough to reach into a human hand.

Seeing this scene, the flying needle master hurriedly reached out and grabbed the tray in Wan Qingping's hand, and then with a flick of the flying hand, thirty-six green mangs immediately shot towards the gap.

"Bang!", the moment the wind and wood drilled into the furnace, the mysterious power pulling the furnace lid seemed to disappear, and the gap closed again.

"Speculum endoscope!" Standing in place for a while, the old man's gaze never left the Heaven and Earth True Law Furnace that was constantly tumbling in the magma, and when the furnace was completely turned red, he commanded to his side.

The youngest apprentice hurriedly straightened the magic control disk in his hand, and as a few magic decisions were pinched out, the magic control disk was magnificent, and a ripple appeared, and the ripples continued to shake the void, and after a while, a mirror-like thing was generated in front of everyone's eyes.

Wan Qingping looked at it, and the mirror was full of a slightly purple crimson, but there were thirty-six subtle things that were constantly rolling in the red.

"Master's good means, but I don't know who arranged this formation, but it can actually reflect the situation inside the furnace, and ordinary mirror formations can't survive in such a scorching environment!" he opened his mouth to praise.

Master Flying Needle laughed, quite complacent: "The old man didn't give it in vain when he traveled in the Momba grassland, and he made some good fortunes, this formation was arranged by a Jindan monk of the Shatuo clan who was proficient in the formation, and the old man didn't expect to be able to map the image so clearly!"

Wan Qingping nodded, no wonder, it turned out to be a Jindan monk of the Shatuo clan.

In addition to the Jiuli tribe around the Mumba grassland, there are dozens of large and small tribes, but most of them have to rely on the Mumba people because the population is not as good as the Mumba tribe.

Since these tribes have been able to survive to this day, they are more or less a bit of a ghost, just like Jiuli is proficient in refining, this Shatuo clan has studied formations since ancient times.

"The four of you, in groups of two, take turns fanning the fire with silver bald fans, the first day is two percent of the fire, and each day passes, one percent more, understand?" the old man commanded as he turned to the four apprentices.

"Understood, Master!" the four said in unison, raising the silver banana fan in their hands.

The old man didn't seem to be at ease, and said: "The third one, you have the most accurate grasp of the heat, you will spend more time, increase the fire by one every day, and you will divide it into twelve periods!"

"Master, in the past, refining treasures and increasing the fire by one percent every day, wasn't it all arbitrary, why should it be so precise?" a tall, thin man was a little surprised by the old man's words.

"Hmph, you ghost baby, you know that you are lazy, this treasure refining may be the best kind of flying needle that the master has refined in his life, no matter how careful he is, he can't be too careful!"

"Yes, Master!" The tall and thin man's face showed a look of surprise, no wonder he used such a big posture this time, with his master's love for the magic weapon of flying needles, it was normal.

So he immediately said to the short man: "Senior brother, let's go in a team, let's try it with seven points of fire first!"

The short man knew that his junior brother was quite talented in the fire, so he didn't say much, nodded, and directly turned the banana fan in his hand three times in a row, and every incitement seemed to have a special rhythm, giving people a pleasing feeling.

The banana fan rolled up with a roll of glow, a whirlwind was generated out of thin air, and after a little circle, it drilled into the hole of the heaven and earth true law furnace.

Master Flying Needle glanced at the mirror in the air, nodded with satisfaction, and then said, "Ten Thousand Daoyou, the fire refining needs to last for eighteen days, let's wait in the stilted building, right?"

Wan Qingping's face showed a hint of hesitation, didn't this old man attach great importance to this treasure refining, why did he let go of the fire refining to his disciples now, instead of controlling it himself?

Master Flying Needle seemed to know his doubts, and smiled: "The fire refining lasts too long, and the refining behind is very painstaking, the old man needs to recuperate, so that the refining in the back will not go wrong, fellow Daoists, rest assured, these apprentices of mine have all obtained a few points of my true inheritance, and they will definitely not even be able to do this little thing well!" After a pause, he said: "Don't hide it from Daoyou, in the past, when the old man was refining treasures, he was left alone for this joint, but now it is controlled by the apprentices, and it has been ......."

"Don't blame the master, it's Wan...... Ahem...... Wan Qingping's face showed embarrassment, people used to let it go, but now the four apprentices are in control of the fire refining, which is already very face-saving, and they all blame themselves for not knowing the doorway inside, so they made a joke.

Fortunately, the old man didn't take it to heart, and then the two walked out of the refining place along the stone steps.

During the period of fire refining, the old man did not just recuperate, and he also took out the Starfall Heavenly Fire Liquid in the "Crane Blood Stone" and mixed it with rootless water for quenching.

Originally, it was planned that the fire refining would last for 18 days, but on the 13th, the little apprentice came to me with a panicked face and said, "Master, the thirty-three branches have not generated new white ash for a whole hour......

Master Flying Needle was a little puzzled, although he had not refined seven thousand two hundred years of wind wood before, but according to some sporadic records in the classics, coupled with his inference, it should take at least eighteen days to complete the fire refining, so as to get rid of some impurities, how can it be ...... now?

Wan Qingping was shocked, but he knew the reason, it was nothing else, but the thirty-six branches were not naturally generated, and they were too little trained by Gangfeng, so they were not so strong and fire-resistant.

But fortunately, the flying needle master did not pursue it, remembered the branches in the furnace, and hurriedly escaped and shot towards the crater.

In the mirror, the thirty-three wind-grown wood branches are almost the same color as the flame at this time, and the surface is calcined and extremely smooth, but the other three branches still have a few dust-like white ash generated under the flame **** from time to time, which shows that the impurities have not been removed.

The old man frowned, and after thinking about the pros and cons for a moment, he ordered without hesitation: "Reduce the flame to a minimum and prepare to open the furnace!"

Hearing this, the little apprentice immediately made a few moves towards the control plate, and the other two apprentices who were fanning the fire also stopped shaking the treasure fan.

Half an hour later, there was a buzzing sound, and the lid of the furnace once again revealed a crack, and it was red.

Taking advantage of this gap, the old man spoke: "Wan Daoyou, in order to form a set of magic weapons, the other three flying needles that have not yet been calcined to the best heat can only be ......."

Wan Qingping knew that the old man couldn't be blamed for this, so he immediately said: "Although the master lets it go, there is no objection to it!"

The Flying Needle Master nodded, flipped his left hand, and a palm-sized, jade disk-shaped object appeared, the edge of this object was very sharp, and it shone with a cold glow against the firelight, it was the Tianyun Crystal Mill borrowed from the Sanmiao Secret Vault.

"Little Four, take out a flying needle prototype, and open the magic weapon for the teacher!"

The little apprentice was not ambiguous, and once again clicked on the Dharma Control Plate, and then saw a flame burst out of the Heaven and Earth True Law Furnace, coming to the outside world, and the flames on it collapsed and dispersed, revealing the body that had been burned red.

Seeing this, the old man immediately poured mana into the Tianyun Crystal Mill in his hand, and soon a series of arc-like phantoms like blades appeared on the edge of this thing.

As soon as the sky cloud crystal grinded, with a "whoosh-" sound, an arc phantom flew out, skimming the edge of the branch very accurately, and then collapsed and dispersed in the distance high in the air.

Wan Qingping stared at it, and saw that at the moment when the phantom passed by, a few very small sawdust-like things fell from the edge of the branches.

Not only that, the arc phantom seemed to have some gray points of light, but the moment they touched the branches, these gray points of light immediately drilled into the branches.

"This day the cloud crystal mill is really extraordinary, and the damage to the structure of the tree branch is minimal!" The old man looked at the light point that drilled into the tree branch, and couldn't help but praise it, and then turned the disc again, and the phantom flew out again.

It takes a lot of time to open the blade, and the branches are only an inch in size, so it takes extremely delicate control to open the blade just right, and thanks to the old man's skill, and it is the peak cultivation of the middle stage of Jindan, it took more than forty days to open all the thirty-six branches.

The old man breathed a long sigh of relief, his face showing an extremely tired look, but there was also a hint of satisfaction, for the refining master, there was nothing more than a perfect work to reward his hard work.

"Ahem, fortunately, the old man has made more preparations, otherwise the mana will really not be able to help!" As he spoke, the old man took out a long-necked bottle, and when the cork was uncorked, a faint fragrance wafted out.

Seeing the look of doubt on Wan Qingping's face, the old man explained: "This is the two drops of "Demon Pill Essence" given by the Southern Barbarian Li Santong Venerable a few years ago when he asked the old man to refine the treasure, worried that the old mana would not be strong!"

It's what a luxury!
