"What a powerful mental power!"

Feeling the fluctuations of the spiritual power that seeped out of the old man's body, Fan Chen's eyes also flashed with a look of shock, the former was afraid that just by relying on this powerful spiritual power, he would be able to compete with the strong man of the Supreme Cultivator.

After luring the mortal dust here, the maid respectfully exited the hall and closed the door with her backhand.

"Master Yun, junior Fan Chen, if there is any disturbance, I hope to bear with me" For this old man who has stepped into the intermediate refiner, Fan Chen gave great respect and said politely.

"Let's get down to business" Master Nayun glanced at Fan Chen, and his voice was unwavering.

Fan Chen nodded, didn't talk nonsense, and with a grip on his palm, the overlord's spear flashed out, stomped lightly, and said: "Master, my ancient spear has not been completely refined, so it is only the peak of the Spirit Supreme, so I want to ask the master to help me complete the last step!"

As he spoke, Fan Chen flicked his fingers, and the overlord spear in his hand slowly floated towards the Yun master, who took it with a calm face, gently wiped his palm on the gun, and a touch of surprise was also crossed on his old face, he looked up at Fan Chen, and said slowly: "This spiritual weapon is quite unique, but if you want to complete the last step, you still need a lot of materials."

"The materials are already in place"

With a wave of Fan Chen's palm, a lot of materials flew out of the spatial ring and landed in front of the cloud master.

"Hmm" After checking the materials, Master Yun nodded, and then said lightly: "Five million top-grade spirit stones"

Hearing this price, Fan Chen's eyes twitched fiercely, just to help complete the last step of refining, it actually required five million top-grade spirit stones, this damn it, it was too ruthless.

"It's dark!"

scolded fiercely in his heart, but Fan Chen still nodded helplessly, and threw out a space ring, which was the only top-grade spirit stone in his body, and from now on, he would completely become a poor ghost with a net worth of no more than 10,000 top-grade spirit stones.

The Yun master calmly took the space ring, did not check it, casually threw it into a Ding furnace behind him, and then said lightly: "Refining takes three hours, these three hours, you can stay here, but don't make any sound, otherwise you will leave by yourself, in addition, refining has a failure rate of thirty percent, and the failure result is that the ancient spear materials are destroyed."

Fan Chen nodded slowly, he already knew that although the failure rate of thirty percent made him a little worried, compared to the failure rate of more than fifty percent of other low-level refiners, he still felt that it was more important to spend more money and feel at ease.

"Whew"

With a prayer in his heart, Fan Chen also sat down on the spot, the spear of the overlord was very important to him, and in these three hours, he didn't plan to leave half a step!

"You have to succeed"

Looking at Master Yun, who was about to start work, Fan Chen also muttered in his heart.

Looking at Fan Chen who chose to stay here, Master Yun only glanced at him lightly, and didn't say anything, he flicked his fingers, and the overlord spear 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 that was suspended in front of Master Yun with an almost transparent color, Fan Chen's heart was also shocked, and he understood that this was the legendary spiritual fire, a kind of spiritual flame that could only be born after the spiritual power was condensed to the extreme.

A large part of the reason why the attack power of the refiner far exceeds that of ordinary people is because of the existence of this spiritual fire, in the face of this spiritual fire, even if the spiritual power cultivation has reached the supreme cultivation, he does not dare to have the slightest neglect, 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 cause much harm to the physical body, but it has an extraordinarily strong corrosive force for the spirit.

After summoning the spiritual fire, Master Nayun's face also slowly became solemn, and with a wave of his robe, the spiritual fire spread out, wrapping the overlord's spear in.

"Squeak!"

With the surging of spiritual fire, the Overlord's spear suddenly trembled violently, and the tiny scales covered all over his body actually showed some signs of opening at this moment.

In response to this situation, Master Yun's face remained unchanged, and he opened his mouth to spit out a 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 floor, corroding into tiny holes.

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

Under the gaze of mortal dust, the dark golden metal material, after consuming it for a full hour, completely turned into a viscous golden liquid.

After the refining was completed, Master Yun's withered fingers flicked, and the golden liquid was extremely evenly spread on the Overlord's spear.

"Snort!"

As these dark golden liquids were smeared, the overlord's spear trembled more and more intensely, and those liquids, under the tempering of the spiritual fire, were integrated into the body of the spear with a trace of it, so that the color of the ancient spear gradually added a trace of dark gold luster, and faintly, the body of the spear seemed to become more slender.

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

This kind of continuous refining material lasted for half an hour, and during this period, Fan Chen's eyes did not close 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 time the time had reached two hours, the last line of material had melted into a liquid and adhered to the Overlord's Spear.

At this time, the color of the Overlord's spear was a little colorful, which was very different from the original red, and every part had some different colors, which was because the refining had not yet been completely completed.
