Looking at Lin Dong choosing to stay here, Master Cheng only glanced at him lightly, and didn't say anything, he flicked his fingers, and the Heavenly Scale Ancient Halberd in front of him was levitated, and then, I saw that in his eyes, there was a sudden flash of flames, and finally it directly penetrated his eyes and burst out.

"Spiritual fire!"

Looking at the flame suspended in front of Master Cheng with an almost transparent color, Lin Dong's heart was also shocked, he understood that this was the legendary spiritual fire, a kind of spiritual flame that could only be born when the spiritual power was condensed to the extreme.

A large part of the reason why the attack power of the spirit rune master far exceeds that of ordinary rune masters is because of the existence of this spiritual fire, in the face of this spiritual fire, even if it is a strong person who has reached the Qi Creation Realm through Yuan Force cultivation, he does not dare to slack off in the slightest, after all, as long as he is hit hard by this thing, it is very likely that he will leave some extremely serious sequelae.

The spiritual fire does not do much harm to the **, but it has a particularly strong corrosive force for the spirit.

After summoning the spiritual fire, Master Cheng's complexion also slowly became solemn, and with a wave of his robe, the spiritual fire spread out, wrapping the Heavenly Scale Ancient Halberd in.

"Squeak!"

With the surging of spiritual fire, the Heavenly Scale Ancient Halberd suddenly trembled violently, and the tiny scales that were densely covered all over its body actually showed some signs of opening at this moment.

In response to this situation, Master Cheng's face remained unchanged, and he opened his mouth to spit out a ball of spiritual fire, wrapping a piece of dark golden metal material in.

"Whew!"

Under the scorching of the spiritual fire, the hard metal material also gradually melted at a slow speed, and some gray-black impurities dripped down from it and fell on the ground, corroding into tiny holes.

Lin Dong sat quietly in the hall, watching Master Cheng's every move without blinking, he was also a talisman master, he could feel that while refining the metal material, the latter's spiritual power was also inextricably poured into it, changing into countless subtle structures, this is an extremely complex job, and only a strong person with strong spiritual power can achieve such subtle control.

Under Lin Dong's gaze, the dark golden metal material, after consuming a full three hours, completely turned into a viscous golden liquid.

After the refining was completed, Master Cheng's withered fingers lightly smeared the golden liquid on the Heavenly Scale Ancient Halberd very evenly.

"Snort!"

As these dark golden liquids were smeared, the Heavenly Scale Ancient Halberd trembled more and more intensely, and those liquids were also tempered by the spiritual fire, and a trace of them were integrated into the body of the halberd, so that the color of the ancient halberd was gradually added to a trace of dark gold luster, and faintly, the body of the halberd seemed to become more slender.

After completing this step, Master Cheng began to refine other materials, for these repetitive actions, Lin Dong did not show the slightest boredom, and looked intent, like a studious disciple, any subtle actions of Master Cheng were included in his mind.

This kind of continuous refining material lasted for a whole day, and during this period, Lin Dong did not close his eyes half a time, and his cultivation reached the point where he didn't sleep for ten days, it was nothing, and his strong body was enough to cope with the exhaustion in the eyes of these ordinary people.

By the evening of the second day, the last of the ingredients had melted into a liquid and adhered to the Celestial Scale Halberd.

At this time, the color of the Heavenly Scale Ancient Halberd was a little spotty, which was very different from the original crimson, and each part had some different colors, which was because the refining had not yet been completely completed.

"Fun"

After refining the last material, Master Cheng also breathed a sigh of relief, glanced at Lin Dong, and said lightly: "I'll reply first, and then start the last step, this step, I will integrate the various characteristics of these rare materials into the ancient halberd, if it is successful, your ancient halberd can become a high-level spiritual treasure, but if the fusion fails, it will destroy the original structure, thus destroying the ancient halberd." ”

Hearing this, Lin Dong's heart suddenly tensed, and he nodded heavily.

After the words were spoken, Master Cheng closed his eyes directly, and recuperated for a full five hours before he opened his eyes, at this time, his spiritual power had almost recovered, and then, his eyes were slowly solemn, his mouth opened, and an extremely powerful spiritual power surged out, wrapping the Heavenly Scale Ancient Halberd that became gorgeous.

"Boom!"

A wave of heat spread through the hall, this heat wave was very strange, obviously not too hot, but it made people feel like they were in a furnace.

A spiritual power poured out from the Lin Dong Mud Pill Palace, enveloping all the body, and that strange heat wave was dissipating and invisible, his gaze stared at the Heavenly Scale Ancient Halberd that was wrapped in the raging spiritual fire, he knew that now was the most critical moment.

"Squeak!"

In the face of the spiritual fire that suddenly became much more fierce, on the scale of the ancient halberd, there was a trace of green smoke seeping out, and the many liquids that adhered to the surface of the ancient halberd were also boiling, and under the pressure of the spiritual fire, they continued to erode the slightest trace of the ancient halberd.

"Buzz!"

As these metal characteristics invaded the interior of the ancient halberd, the balance in it seemed to be broken, the halberd body shook wildly, and there was a faint humming sound coming from it, and a dazzling strong light also burst out from the ancient halberd, and the sharp luster burst into the hall, and the luster was full of strong destructive power.

"Humph!"

Feeling the resistance of the ancient halberd, Master Cheng also snorted coldly, and a strong spiritual power surged out, forming a spiritual prison, wrapping the surrounding of the Heavenly Scale Ancient Halberd with more than ten zhang of metal, and those lusters shot on the spiritual prison, shaking ripples, and then they dissipated.

"Give me fusion!"

Master Cheng's eyes were solemn, and then his big hand suddenly clenched, and the spiritual fire that wrapped the Heavenly Scale Ancient Halberd shrank fiercely.

"Whew!"

With the fierce compression of the spiritual fire, all the metal liquid on the ancient halberd was directly pressed into the ancient halberd, and in an instant, the brilliant luster burst out from the heavenly scale ancient halberd, and the surrounding spiritual prison was directly pierced by the sharp luster, leaving a bottomless black hole on the ground.

"What a domineering spirit treasure!"

Seeing this scene, Master Cheng's eyes also flashed with a look of surprise, and he immediately grabbed it with a big hand, and an invisible spiritual power big hand firmly grasped the ancient halberd that burst out with a brilliant luster.

Lin Dong looked nervously at the Heavenly Scale Ancient Halberd struggling in Master Cheng's hands, and he could vaguely see that in the midst of the surge of light, the shape of the Heavenly Scale Ancient Halberd seemed to be undergoing subtle changes, and the sharp taste was getting stronger and stronger.

"Buzz!"

The rapid humming sound continued to come from the Heavenly Scale Ancient Halberd, and later, that humming sound seemed to gradually evolve into an extremely low strange dragon groan.

That kind of sound quietly echoed in the hall, but it made the faces of De Lin Dong and Master Cheng change a little at the same time, the former was surprised, and the latter was shocked, obviously not expecting that this ancient halberd could actually emit the sound of that legendary divine beast.

"Whew!"

In Master Cheng's shock, above the Heavenly Scale Ancient Halberd, the strong light was so strong that it directly exploded its spiritual power, and an extremely sharp light burst out, directly blasting the ceiling of the hall to pieces.

"Come here!"

Lin Dong hurriedly beckoned, and the bright light suddenly swept over, and finally appeared in his hand with great obedience.

Lin held the Heavenly Scale Ancient Halberd in his hand, stomped on the ground heavily, the light on it slowly weakened, and when he looked at it, a touch of amazement suddenly appeared in his eyes.

Today's Heavenly Scale Ancient Halberd, the shape is more slender than before refining, and the fine scales on the halberd body have also become more inclined to a thick dark golden color, but what makes Delin's eyes tighten the most is that between the scale structures, a dragon-shaped scale pattern has been faintly formed, which looks extremely magical.

At the tip of the halberd, two circles of sharp arcs extend left and right, and the cold light surges, hideous and bloodthirsty, like the huge open dragon's mouth, which can swallow the heaven and the earth, and the momentum is amazing.

"Good!"

Grabbing the Heavenly Scale Ancient Halberd, Lin Dong couldn't put it down, and there was a surge of ecstasy in his eyes, today's Heavenly Scale Ancient Halberd, compared to before, I don't know how much stronger, according to Lin Dong's expectations, even compared to Wang Yan's Da Luo Golden Gun, the Heavenly Scale Ancient Halberd is not allowed at all!

"What a baby!"

And just when Lin Dong couldn't put it down and played with the Heavenly Scale Ancient Halberd in his hand, the closed hall door was suddenly pushed open, and a figure walked in, staring at the ancient halberd in Lin Dong's hand with fiery eyes, and there was a strong greed in his eyes.

The person who suddenly broke in made the faces of De Lin Dong and Master Cheng change, and their eyes sank when they looked at it.

"Huazong!"

Looking at the person who broke in, Lin Dong's eyes sank slightly, this guy turned out to be the Hua Sect of the Yin Puppet Sect!
