Ye Han sat in the flames, covered with a faint frost beside him, driving away the heat here.

In front of him, there was a large piece of white copper, which was the main material for the little princess to provide him with sword refining.

Wind and snow white copper, with both wind source power and water source power, is a rare metal such as thunder fire steel, from this point of view, it is a grade higher than Xingchen iron.

A large piece of white copper was placed in front of the night cold, facing the boundless fire, flashing with a little white light, and the light mist evaporated from above, but it did not dissipate, but was wrapped in a whirlwind, circling around the copper block.

I have to say that the people of the royal family are generous, but they are just refining a long sword, and they actually directly gave Ye Han eighty catties of wind and snow white copper, even if you take into account the consumption caused by the loss of sword refining, these are enough to refine two or three long swords.

Of course, the little princess won't know that in fact, when the night is cold and refining the sword, she can't even use half a catty.

These have all become the tonic of the Heavenly Dao Peerless Sword.

Touching the white copper block in his right hand, Ye Han guided the power of the Heavenly Dao Peerless Sword, and since he merged with the Heavenly Dao Peerless Sword, the speed of absorbing rare metals was also much faster.

The wind and snow white copper was getting smaller at a speed that was visible to the naked eye, but the aura of the night cold was getting stronger and stronger, slowly rising on the basis of the fifth order of the sword heart realm.

In just a moment, the white copper turned into an ordinary piece of refined copper, and no more mist appeared, exposed to the flames, and gradually began to melt.

And Ye Han was also completely stabilized at the fifth order of the sword state of mind, and the essence of light flashed in his eyes, full of fierce sword intent.

Then, he took out a long sword template and began to refine the sword for the little princess.

In Hellfire, there are flames everywhere, and as far as the eye can see, there is an endless monotony, and even though the flames are brilliant and colorful, anyone who stops here for a long time will feel bored.

Three days had passed since the night cold began, but the long sword had still not been formed.

Even he himself didn't expect that refining a long sword would be so difficult.

If there was only wind and snow white copper, I am afraid that ten would have been refined, but even if he exhausted his true qi now, it would only be half of the success.

It's all because of that small piece of Spiritual Heart Blue Gold.

In order to raise the longsword to eight stars, Ye Han had to refine a small piece of Lingxin Blue Gold, and for him, it was necessary to copy the laws of Lingxin Blue Gold on the longsword.

This is an extremely energy-consuming work, and each of those blue gold laws represents the laws of heaven and earth, and only by concentrating and feeling with your heart can they be portrayed, and at the same time, they can also provide enough true qi support.

In the boundless fire, there was no heaven and earth aura at all, and Ye Han had no choice but to maintain his true qi by consuming spirit crystals, otherwise, such a fire would not last long even if it was a supreme battle body.

If it weren't for the fact that he possessed the spiritual power of the Sword Soul Realm, this kind of casting process would probably have been greatly extended.

Another five days passed, and Ye Han finally completed the casting process exhausted, his true qi was about to be exhausted, and even most of his spiritual power was consumed.

In his hand, he held a silver-white long sword that shimmered with a fine blue light, and even if it was not infused with true qi, there was a faint brilliance flowing.

The eight-star sword, just by looking at it, you can find its extraordinary, those small blue lights seem to contain mysterious power, flickering, making people's hearts continue to stir.

The current night cold has finally reached the level of an eight-star sword refiner.

This kind of sword refining technique is probably enough to be proud of any sword refining force in the Emperor Domain.

After resting, Night Cold once again entered the flames, and in such a fire, it was easy for rare metals to appear.

At this moment, he suddenly missed Lin Mengxi very much, when she was in the Fengyun Mountain Range, she could see at a glance whether there were metal mines in the mountain, if she was around, she wouldn't need to look for it so hard.

Darkness descended, guarding his side, while the cold air fed against the heat outside.

Ye Han walked into the depths of the flames, attacking the surroundings as he went, huge sword rays passing through the flames and smashing into the ground with a sonorous sound.

The earth here can no longer be called land, the molten metal has already seeped into it, coupled with the burning of the flames, the earth here has become extremely solid, even if Ye Han shoots with all his strength, it will cut down at most three feet deep.

A day passed, Ye Han had searched the range of the red flames, but he still didn't find anything, and the ground was chopped by him, like a deep scar left after the battle.

After thinking about it for a while, he decided to go one step further, his true qi could last for a long time, and if he could really discover any metal ores, it would be an unimaginable treasure for him.

The surrounding flames gradually turned blazing white, and the temperature suddenly increased a lot, the flames in this layer had far exceeded the fire of the Heavenly Sword Pavilion, if it was an ordinary sword mind realm swordsman, he would definitely not be able to hold on here.

The heavy defenses of the night cold could no longer completely block such a high temperature, and a little residual heat seeped in, making him feel a burning pain.

There is no day or night in the flames, and Ye Han feels the flow of true qi in his body, ready to leave as soon as his true qi is exhausted.

It's another round of searching......

"Boom!"

A sword slashed out, and the ground in front of him shattered, and a hole appeared.

Ye Han looked carefully, but he didn't find any rare metals, and he couldn't help but be a little disappointed.

"Whew!"

At this moment, a violent wind suddenly set off at the entrance of the cave, and then, as if it was under some control, the blazing white flames seemed to be under control, and they desperately gathered in the cold of the night!

"What's going on?" Ye Han's heart froze, and his body suddenly moved more than a dozen steps away, and the flame hit where he was before!

"Boom!"

The condensed flames glowed with cyan light, and exploded directly at that location, and the cyan flames scattered, and then they converged again, condensed into a cyan dragon, and swept towards the night cold!

The night cold man and sword unity, ten thousand swords duel together, increase the speed to the extreme, desperately flee to the periphery.

This is the world of flames, even if he is as angry as the sea, he will not dare to squander it here.

"Whew!"

The cyan fire dragon roared in, with a sky-high flame, this fire dragon had reached the temperature of the third layer, and when it approached, it immediately made Ye Han feel a sharp pain!

"One blade across the world!"

There is no way to avoid it, the night cold ejects the Shura giant sword, and the vast true qi pours in, catching up with the huge dragon head!

The dark red giant sword was so powerful that it directly smashed the cyan dragon into an explosion, but the flames were still endless, and they soon gathered again and besieged Ye Han in it.

"Old skeleton, don't play dead, tell me what's going on?" Night Chill shouted angrily.
