After Lin Yun entered the refining room, he immediately started to prepare for the work, to melt all kinds of ores, remove the waste residue in the ores, and then fuse all kinds of minerals, then forge, quench, etc., this is not something that Lin Yun can deal with alone.

Bai Lao appeared in front of Lin Yun.

"Bai Lao, I'm sorry for you."

"Well, boy, you have to pay attention to it, too."

Lin Yun turned the earth fire to the maximum, and after the refining furnace was preheated, he controlled a piece of ore to slowly approach the refining furnace, carefully letting the flames slowly melt it.

Subsequently, the ore melted into a molten liquid, and Lin Yun controlled the liquid to start rotating, using centrifugal force to throw out the impurities.

A quarter of an hour later, Bai Lao nodded, and Lin Yun controlled the melted ore to be placed in the other outlets of the refining furnace, controlling the ore from solidifying, and then began to refine the next piece of ore.

A day later, Lin Yun's face was pale, he sat cross-legged on the ground and gasped, using half a day's soul power in one breath to refine hundreds of fast ores, which was much more difficult than alchemy.

Moreover, it is very difficult to melt and refine a lot of ores, as far as that piece of phoenix feather stone is concerned, it took two hours to burn.

"It would be much more convenient if there was a strange fire."

Lin Yun said.

Then Lin Yun ran the "Meditation Technique" and began to slowly recover his soul power, and the next time was even more difficult.

Just when Lin Yun regained his soul power. Bai Lao began to control the melted ore and began to fuse.

Bai Lao first fused some resilient minerals together, and then used his soul power to pull them into the shape of a sword to make a sword embryo.

Then, the sword embryo began to be roasted on the blazing fire, and the drops of impurities were quenched out by the blazing fire, and the size of the sword embryo was further reduced.

After that, Bai Lao began to control the other minerals to be evenly distributed on the sword embryo layer by layer, and when the last layer of minerals was covered, a broadsword five feet long and one palm wide appeared.

At this time, Lin Yun also regained his soul power.

"Bai Lao, the sword embryo has been completed?"

"Yes, the next step is to beat it, and I haven't forgotten about the soul transformation!"

"You taught me two months ago, and I gave up practicing one day."

"Well, that's good."

Immediately, a small hammer condensed by soul power appeared in front of Bai Lao, and Lin Yun controlled a hammer to fly, the hammer was not big, but it was made of Chongyue stone, it was very heavy, and the melting point was very high, and many refiners made it into a hammer that hammered the embryo.

Lin Yun controlled the hammer and floated to the side of the sword embryo, Bai Lao's hammer hit that position, Lin Yun also immediately hit the hammer to that place, and with each blow, sparks splashed everywhere, and impurities were beaten out.

A quarter of an hour later, Bai Lao took out a bucket of blood and put the sword embryo into the blood, and the blood boiled instantly.

"This blood seems to belong to the giant spirit snake!"

Lin Yun wiped his sweat and said.

"Yes, I kept some for quenching."

Then, the white veteran took out the sword, turned up the flame, continued to scorch, and then thrashed.

In this way, back and forth, it took seven days to hammer, and even the hammers that were difficult to melt melted six, and Lin Yun also had to stop a few times in the middle to recover his soul power and physical strength.

On the eighth day, with the fall of the last hammer, the whole sword embryo had become a long sword three feet three inches long and three fingers wide.

"Boy, the djinn serpent's fangs."

Lin Yun immediately took out a snake tooth, Bai Lao took it, put it on the flame, and with a move of soul power, the snake tooth was instantly turned into powder, and immediately, the flame rose, melting the snake tooth into liquid.

Subsequently, the liquid begins to rotate and impurities are constantly thrown out.

A quarter of an hour later, a ten-foot-long snake tooth had become only half a fist in size.

"What kind of forging technique is this?"

"Hehe, boy, to get to this point, the soul power must be at least blue."

"Uh......"

Lin Yun looked at his still pale red soul power, and he had a long way to go.

Bai Lao evenly integrated the liquid melted from the snake's teeth into the blade.

"Boy, it's not enough, another one."

Lin Yun quickly took out a snake tooth again, and Bai Lao fused into the blade again in the way just now.

"Boy, it's now."

Lin Yun's right hand pointed at the sword, and a wound was cut on his left hand, and blood gushed out in an instant, and Lin Yun immediately used his soul power to control it and floated towards the sword.

At the moment when the blood touched the sword, the blood was instantly absorbed by the sword body, and the sword instantly made a sword sound.

With the completion of the final quenching, the sword was finally cast.

Looking at this sword that exuded a faint red color all over his body, Lin Yun reached out and held this sword, and there was still a faint warmth on the sword body.

"Medium-grade spiritual weapon."

Lin Yun felt the grade of this sword.

"Boy, give it a name! Not surprisingly, this sword will accompany you for the rest of your life, and you will be with you to slay all the powerful enemies. ”

Lin Yun casually looked like a sword flower.

"The whole body is red, and the sword qi is long in the sky, so it's better to call it Chixiao."

Immediately, Lin Yun carved the word "Chixiao" on the sword body above the sword jaw.

The blade of the sword let out a sword sound, as if it was happy that it had received a new name.

"Boy, when you find the ore in the future, remember to integrate it into the sword body, it will continue to improve."

"Is there still this effect?"

"That is, none of the weapons I forged were mortal."

"Well, I see, Bai Lao."

So no one thought that in the future, the famous sword Chixiao of the three thousand worlds was born here, and it accompanied Lin Yun to kill countless enemies, and even later generations said that Chixiao Sword killed too many people, and the enemy's blood stained Chixiao red.

Lin Yun put Chixiao into the ring, and then, breathed in this refining room to recover his soul power, while Bai Lao used the remaining materials to build Chixiao to create a short sword that was only one foot long, which was also put away by Lin Yun.

Then, Lin Yun pushed open the door of the refining room that had been closed for ten days, and he still looked like an old man.

"Sir, you're out."

The director of the Heavenly Treasure Pavilion who was in charge of the refining room greeted him.

"Well, it's been a little longer, but it's still rewarding."

"Then congratulations to the old man, old man, is there anything else you need?"

"The old man needs a scabbard."

"Okay, Cui'er, take this old gentleman to pick a scabbard."

"Yes, old man, please come with me."

A maid walked in and said politely.

In the end, Lin Yun picked out a scabbard made of deep-sea shark skin, put the Chixiao Sword in it, and then left the Heavenly Treasure Pavilion.

After Lin Yun spared a few laps to confirm that he was safe, he recovered his appearance and returned to Qingyun Sect, the matter of forging the sword has been completed, Lin Yun plans to prepare it, and go home during the New Year, as for whether to worship the mountain peak, let's talk about it when I come back.
