Du Yusheng, who was considered a fool, was in the Immortal Mansion at this time, circling around the sealed jade box.

No one else could open the seal of the jade box, but she could.

This jade box can be frozen by the extremely cold aura of the ice phoenix feathers, then it will definitely be burned by her phoenix true fire.

She wasn't worried about how to break the seal, she was just worried about whether she would be able to face the extreme cold after breaking the seal?

After circling the jade box for a long time, she finally made up her mind, turned back into the phoenix body, flew into the air, and sprayed a mouthful of phoenix true fire towards the jade box.

In the blink of an eye, the huge jade box burst into flames.

Du Yushang was like a great enemy, and he hurriedly sacrificed the true fire of the phoenix, forming a fire shield, wrapping himself tightly from beginning to end.

A moment later, the jade box was burned to ashes, and after the nine ice phoenix feathers lost their restraints, they were carried by the extremely cold qi and flew into the air, and an extremely cold aura spread in the immortal mansion, not only the ground froze, but even many ice flowers formed in the air.

And Du Yusheng, who was wrapped in the phoenix true fire, was also frozen and shivered in an instant, and then he heard the crisp sound of the phoenix true fire shield being frozen into ice and then shattering.

Du Yushang didn't dare to be careless at all, the Phoenix True Fire Shield was frozen layer by layer, so she replenished it layer by layer, and when her spiritual power was not enough, she ate two Peiling Pills.

As the Phoenix True Fire gradually refined and condensed in the confrontation with the extremely cold qi, Du Yusheng, who was originally at a disadvantage and could only rely on constantly eating Pei Ling Pill to replenish his spiritual power, finally breathed a sigh of relief.

Fortunately, there is a phoenix true fire, otherwise there will be no such person as Du Yushang in this world from now on.

After about a day or two, there seemed to be some kind of balance between the Phoenix True Fire Shield and the Extremely Cold Qi, and the flames on the outer layer of the shield were no longer frozen into ice, but the Phoenix True Fire could not help the Extremely Cold Qi either.

In this delicate balance, Du Yushang couldn't help but think that in this auction, at least one-third of the heavenly and earthly treasures came from the Tianquan Secret Realm, if it weren't for the wrong time, she would have thought it was a special auction of the Tianquan Secret Realm.

And that place even has ice phoenix feathers that don't belong to this realm, no wonder the mortality rate is so high, the monks still want to go, but it really responds to the sentence that people die for money.

In the following days, the delicate balance between the Phoenix True Fire and the Extremely Cold Qi was gradually broken, and the Phoenix True Fire, which became more and more condensed and pure under the tempering of the natural enemy, finally suppressed the ownerless and rootless Extremely Cold Qi, and achieved a phased victory in this contest.

And Du Yusheng, who was wrapped in the Phoenix True Fire Shield and didn't dare to move, was finally able to roam in the Immortal Mansion again, although he still had to wear the shield......

A few days later, the originally fierce and mighty extremely cold qi was completely suppressed by the Phoenix True Fire within the nine ice phoenix feathers, and it was no longer possible to act as a murderer.

And Du Yusheng, who had been on the Phoenix True Fire Shield for nearly ten days, dared to return to his human form at this time, and circled around the ice phoenix feathers that had reined in his ferocity.

She was thinking about how she could refine the nine feathers into clothes.

Although the phoenix true fire is known as burning everything, it really can't refine the ice phoenix feathers.

I don't know if the refined Gengjin can cut the ice phoenix feathers, if not, I have to refine the natal magic weapon first, and then find a way to slowly grind with these feathers.

Du Yushang took out the heptogen gold from the storage space, and a mouthful of phoenix true fire sprayed over, slowly refining the impurities contained in the giant heptogen gold.

After a day, heptyl gold had shrunk in half.

Two days later, only a quarter of the original amount remained.

Seven days later, Gengjin was only the size of a watermelon, and no matter how much the phoenix's true fire burned, it could no longer shrink by a fraction.

Du Yushang used his divine sense to pull out a wisp of Gengjin that had been burned into a liquid state by the Phoenix True Fire, and then pressed it into an extremely thin piece.

As soon as this extremely thin piece of Gengjin flakes approached the ice phoenix feathers, it instantly solidified into a blade, and then was frozen into ice cubes.

Du Yushang spewed out a mouthful of phoenix true fire, melted the ice, burned the extremely thin Gengjin blade again and refined it, and then repressed it into a blade, and then brought it close to the ice phoenix feather.

After going back and forth like this for nearly a hundred times, the extremely cold aura emitted by the Ice Phoenix Feather could no longer freeze the Gengjin Blade.

At this time, the Gengjin blade, after repeated tempering of extreme cold and heat, has become extremely sharp to an unprecedented extent, Du Yushang did not dare to hold it in his hand at all, just getting closer, he would be scratched by its edge.

She controlled the Gengjin blade with her divine sense, and cautiously approached the Heavenly Phoenix Feather, even if she was protected by the Phoenix True Fire, she still felt that her soul was about to be frozen.

But she still persevered, manipulating the Gengjin blade to slash at the small branches of one of the feathers.

However, it does not move.

Du Yushang hurriedly gasped and withdrew his divine sense, and hurriedly used the phoenix true fire to warm himself.

After her consciousness recovered, she controlled the Gengjin blade again, slashing at the tiny fluff attached to the small feather branch.

This time there was a scene, and there was a trace of scratch on the fluff.

Du Yushang couldn't help but rejoice.

It was only a small scratch, but at least it proved that she was on the right track.

Next, you just need to grind it slowly with water.

At first, it took Du Yushang half a day to cut off the first strand of fluff.

The frostbite of her soul was very uncomfortable, and she had to cut a few times before withdrawing her divine consciousness and warming it up with the true fire of the phoenix.

But after a few days, she soon lost her fear of the extreme cold, and was even able to hold on to it until she cut off a fluff.

Since then, she has become more and more efficient, from cutting a single fluff in half a day at the beginning, to almost a quarter of an hour later.

In a month's time, Du Yushang had cut off a bunch of crystal clear ice phoenix fluff, and one of the nine feathers had been shaved to the branches.

In another month, two more feathers were shaved off all their fluff.

At this time, the ice phoenix fluff in front of Du Yushang was already half a person tall, and these fluffs were more than enough to weave a long skirt.

And there is less than a month before the opening of the Tianquan Secret Realm, she still has a lot to do, and she can't fight with those Tianfeng Lingyu anymore.

Du Yushang put the remaining six complete Heavenly Phoenix Feathers into his storage space, and then patiently knitted his clothes with his divine sense.

The fluff of the phoenix feather itself is thicker than the general silk thread, so even the spinning process can be saved, and it cannot be woven into cloth and then cut, because once it is woven into cloth, I am afraid it is not so easy to cut, and it can only be formed as a piece from the beginning and directly woven into the shape of clothes.

This is not difficult for Du Yushang.

As a woman, I'm naturally better at it.

It took her three full days, almost emptying all of her senses, to finally complete this huge project.

At this moment, a beautiful long dress that was white and clear and radiated with ice crystals was suspended in front of her.

This is the result of more than two months.

She raised her hand, and the ice crystal dress covered her, making her shiver from the cold.

Du Yushang couldn't help but smile bitterly: Other people dress to keep out the cold, but my clothes don't seem to be able to keep out the cold, but they also make people even colder.
