In the next few days, Xiao Han did not relax, but used every resource at hand to improve his strength as much as possible.

He first used the Yuan Crystal of the Spirit Devouring Beast and a bottle of Ice Yuan Pill to raise his cultivation to a state of saturation in the middle of the True Yuan Realm, and then used the flesh and blood of the Thousand Phoenix Scales to raise his physical body to the late stage of the Divine Refining Double Heaven.

In this way, his cultivation has entered a new bottleneck, and no matter how much he cultivates, it is impossible to promote to a higher level, but for him at this stage, this strength is enough to be proud, so he didn't force it anymore.

Early in the morning of this day, Xiao Han came to Ziyang Valley early and borrowed an earth fire forging sword furnace from Ouyang Ye, the deputy valley master of Ziyang Valley.

Ouyang Ye was a little surprised by his request, and asked him why he wanted to borrow the earth fire to cast the sword furnace?

There was no way to avoid this question, and he could only say that he wanted to forge a sword.

As the top figure in the refining of the Liuyun Sect, Ouyang Ye said very generously: He can do it for Xiao Han what kind of sword he wants to cast.

Because in his opinion, Xiao Han's Qi Dual Cultivation must have occupied most of the usual cultivation time, and it is impossible for him to be proficient in the art of refining weapons at all!

He wondered if Xiao Han had come to practice the art of sword casting, and if so, he needed to persuade him to specialize in one thing, so as not to take care of one or the other, and in the end the gains outweighed the losses.

In addition, he has other thoughts, he sees that Xiao Han is young and talented, and in time he will become a man of the hour and a top master in the rivers and lakes, so he sells him a favor now in order to meet his needs in the future.

However, Xiao Han's answer was obviously a little insistent, "This is not necessary, the valley master is busy with everything, how dare the disciple have to work?"

Ouyang Ye frowned and said, "Xiao Han, it's not that Uncle Shi said you, your talent in martial arts is indeed good, but this doesn't mean that you can also succeed in refining weapons, you must not be too big, so as not to end up empty-handed."

Xiao Han understood, and only said: "Uncle Shi, don't worry, the disciple knows in his heart that this time it will not take more than ten days to borrow the earth fire to cast the sword furnace, and only this once, he will never deviate from his own path in the future, and he will definitely specialize in martial arts." ”

Seeing that he was so persistent, Ouyang Ye couldn't say anything more, so he had to agree and gave him a pass token.

After thanking him, Xiao Han hurriedly said goodbye.

There is an earth fire spirit vein in Ziyang Valley, and there are seven earth fire rooms, four alchemy rooms, and three refining rooms.

The Earth Fire Refining Room is different from the ordinary refining room, and only refiners who can refine spiritual weapons can enter the refining utensils.

This is also where Ouyang Ye was surprised, if it was an ordinary refining room, Xiao Han didn't have to go to him, he could rent a refining room by paying some fees, but he insisted on casting a sword furnace on fire, obviously wanting to cast a spirit sword.

In his opinion, Xiao Han naturally couldn't forge a spirit sword, so he opened his mouth to forge a sword for him.

However, what he didn't know was that Xiao Han's sword-forging technique was still seven points better than him!

"In the previous life" for a hundred years, Xiao Han not only cultivated martial arts, but also studied alchemy and sword casting, although his achievements cannot be regarded as masters, but he can not compare, not to mention that he wants to cast the best spirit sword, and Ouyang Ye can't cast it.

Entering the depths of the Ziyang Valley, Xiao Han relied on the token given to him by Ouyang Ye to go all the way unimpeded and directly entered an Earth Fire Casting Sword Room.

In front of him was a large sword-casting furnace the size of a square zhang, and on the top of the furnace stood a statue of the god of fire of the Vermilion Bird, with a hole in each of the four corners; On three sides of the sword-forging furnace, there are seven-star wind holes, which can control the amount of firepower.

Directly in front of it is the empty chamber of the sword-forging furnace, and below the hollow chamber is the earth fire vent, which can be opened as long as the vitality is injected.

But he didn't rush to open the fire mouth, but took out a jar of demon beast essence blood from the Qiankun bag, and used it to draw a strange rune circle on the four walls of the sword-casting furnace, and then drew a spirit-gathering circle around the sword-casting furnace as the center, and then took out a few medium-grade ice yuan stones from the Qiankun bag and placed them in several formation nodes of the spirit-gathering array.

These mid-grade Ice Yuan Stones were already prepared by him two days ago, just for today's needs.

Xiao Han's sword-casting technique is different from that of ordinary swordsmiths, and he practices a peculiar sword-casting technique called "Divine Strange Sword Casting Technique".

The most important feature of this swordsmith is that it can maximize the characteristics of the material.

I saw that after the formation rune was drawn, Xiao Han destroyed his vitality and opened the mouth of the ground fire.

In an instant, a raging flame burst out from under the hollow chamber of the sword-forging furnace, and in a moment the entire furnace wall was burned red.

Seeing this, his eyebrows condensed slightly, and he took out the Cold Moon Sword from the Qiankun bag and threw it into the furnace.

Although he was very confident in his sword-forging technique, it was a previous thing after all, and this time before casting the best spirit sword, he wanted to try his hand first, so he decided to use the Cold Moon Sword as the basis to create a medium-grade spirit sword.

After the Cold Moon Sword was thrown, he didn't activate the formation, but let it be burned by the earth fire.

He stared intently at the fire in the furnace with both eyes, and from time to time he destroyed his vitality to control the amount of fire.

When the entire body of the Cold Moon Sword softened, he took out a fist-sized dark black stone from the Qiankun bag, which was the one he had found in the Lin family in Xueyang Town before.

I saw that he casually threw the Moonlight Stone into the sword-casting furnace, and then controlled the furnace fire to concentrate on calcining the Moonlight Stone.

In less than a quarter of an hour, just when the Cold Moon Sword was almost melting, the Moon Yao Stone had already been refined into a dark viscous liquid.

With his eyebrows condensed, Xiao Han quickly mobilized the cloud of liquid, enveloped the Cold Moon Sword, and then activated the formation.

In an instant, a powerful ice energy attack swept into the sword casting furnace, creating a strange and spectacular scene of ice and fire in the same furnace.

The earth fire burned, the cold air froze, and the "Cold Moon Sword" was violently destroyed.

Xiao Han's eyes were blazing, staring at the masterpiece in the furnace meticulously, not daring to slack off at all.

Time passed by minute and second, more than three hours had passed in the blink of an eye, the spectacle of ice and fire was still continuing, and Xiao Han's expression at the moment was also a little solemn, obviously the sword casting had reached a critical juncture.

Gradually, the furnace fire is decreasing, and so is the input of ice energy.

Vaguely, you can see that the new sword in the sword-forging furnace is no longer completely snow-white, but has a little more dark lines, similar to the color of the real moon, and it also exudes a cold breath.

The earth fire calcined the impurities, the cold qi condensed into the sword type, and after repeated tempering, after nine hours, the earth fire and ice vitality were extinguished at the same time.

In an instant, the cold light was shining, and a brand-new Cold Moon Sword was cast.

Xiao Han's eyes condensed slightly, and with a roll of his sleeves, the new Cold Moon Sword flew into his hand with a "brush".

The new sword was started, and it swept through the air twice, and the sword was shaken, and the dragon and tiger roared rolling in, endlessly, and only stopped after a while.

As soon as the connoisseur makes a move, he will know if there is one!

Just through this sword groan, he knew that this sword was a superior sword, although it was only a medium-grade spirit sword, it was already the pinnacle of a medium-grade spirit sword!

Xiao Han showed a satisfied look and muttered: "This Cold Moon Sword can reach this level just by incorporating a piece of Obsidian, it seems that my craftsmanship has not regressed, and now I can cast the best spirit sword with peace of mind!"

After receiving the Cold Moon Sword, he meditated on the spot and breathed for a while, and when his spiritual vitality was almost recovered, he stood up and checked those formations, and after confirming that they were undamaged, he began to refine the best spirit sword.

Opening the mouth of the ground fire, the raging earth fire gushed out again, and when the temperature of the furnace rose almost the same, he directly activated the formation.

In an instant, the ice and fire are once again in the same furnace, and the two are blended, intertwining into a colorful flame.

When the temperature of the furnace reached a stable equilibrium point, he took out several spirit knives and spirit swords from the Qiankun bag, and threw them all into the sword-casting furnace.

It was a bit time-consuming for him to collect all the materials for casting the best spirit sword, so he retreated to the next best thing and chose an easier method, that is, to extract the gold essence from these spirit swords and spirit swords as the material for shaping the sword body.

Gold essence is the purest part of the metallic spirit ore.

Like a fist-sized moon stone, being able to refine gold essence the size of a fingernail is already remarkable, which shows the preciousness of gold essence.

These spirit knives and spirit swords were all obtained by him by killing the enemy a month ago, and they also included the medium-grade spirit knife of the Tiger Overlord Sword Ten Thousand Kills and a medium-grade spirit sword of Chen Yunsheng.

He believed that nearly ten spirit knives and spirit swords should be able to refine enough gold essence.

If Ouyang Ye was here, he would definitely regret it and scold him for being a loser, so many spirit knives and spirit swords were almost worth hundreds of thousands of lower-grade yuan stones, enough to buy two copies of the gold essence needed for sword refining, but he was defeated all of a sudden.

However, Xiao Han didn't care, time was the most important thing for him, rather than spending time on collecting gold essence, he would rather use that time to refine a few more spirit swords, and then it would be a valuable fortune.

Time passed bit by bit, and those spirit knives and spirit swords were gradually melted into a mass of metallic liquid, at this time, Xiao Han dispatched his divine sense, and cooperated with his vitality to slowly peel off the golden essence from those metallic liquids, little by little.

This process was very time-consuming and laborious, and his vitality was quickly consumed by the earth fire, and his divine consciousness would be more or less affected in the earth fire, so after a while, his forehead was covered with beads of sweat.

It took about seven hours or so for him to refine a fist-sized mass of gold essence.

Looking at this mass of golden essence, his face began to become solemn, because the next thing was the main thing.

I saw that he took out a fiery red stone from the Qiankun bag and threw it directly into the sword-casting furnace.

Suddenly, the flames in the sword-casting furnace swelled in an instant, almost overflowing the sword-casting furnace, and the air crackled with the flames.

This fiery red stone was nothing else, it was the red flame stone that Yun Ruxue had given him.
