(Xie Luxie's monthly pass for "maddog998")

The walls of the huge room are made of heavy steel and are equipped with various containments that can be used to reinforce the steel walls several times over, avoiding accidents.

In the huge furnace, there were terrible flames coming out, as if an ancient demon was hiding in it, and the light emitted by the fire illuminated the entire sword-forging room, which was cyan and very strange.

This kind of flame is not an ordinary flame, but a special flame whose temperature is high to a certain limit, called the green steel fire, the green steel fire is enough to melt ordinary metal in an instant, even the metal of the best sword weapon will be melted in a very short time.

Chu Duan stood next to the stove and put a soldering iron in the green steel fire with iron tongs, which was a synthetic metal used to forge Wang Pin's sword.

Before forging the Heavenly Desolate Sword, Chu Duan had to cast other Wang Pin sword weapons as a practice, but the flames in his small shop were not enough to melt the synthetic metal that cast the Wang Pin Sword Weapon.

This is one of the sword casting rooms of the Sword Building, the largest place to buy and sell swords in Tianfeng County.

Only a place like the Sword Tower has a sword casting room that can cast Wang Pin's sword weapons, because it has green steel fire, which is more powerful than ordinary fire.

Renting such a sword-forging room for one day would cost 10,000 high-grade spirit stones, which were very valuable, and the spirit stones needed to support the green steel fire were also produced by themselves.

It didn't take long for the soldering iron to be burned red and cast.

In the entire sword-casting room, Chu Duan was the only one, so he didn't have to worry about being spied on. Chu Duan cast to his heart's content.

The use of mountain shaking and mountain piercing is alternated. More and more sophisticated, but also very expensive.

After a while, Chu Duan finally hammered the sword embryo in his hand into shape, and then, it was necessary to quench water, which was not ordinary water. Rather, it is a kind of cold spring water, and the effect of quenching is better.

"This is the first royal sword weapon I forged. Chu Duan took out his sword weapon from the cold spring water and looked at it carefully. The whole sword weapon is cyan, as if there is a trace of light flowing on the sword body, this is a regular sword weapon. In terms of quality, it can only be regarded as the most ordinary royal sword weapon.

Of course, this is just Chu Duan's practice. It was a kind of preparation for him before forging the Heavenly Desolate Sword.

"Take a break and regain your strength. Begin to forge the Heavenly Desolate Sword. ”

Half an hour later, Chu Duan took out a lot of high-grade spirit stones for the burning of the green steel fire, and then, he took out a piece of metal, all of which were needed to forge the Heavenly Desolate Sword.

In the Heavenly Desolate Sword Codex, it has been very clear how to cast the Heavenly Desolate Sword, and every step is very detailed. Chu Duan had already understood it very clearly, and had even simulated it in the spiritual world.

All the metal that forged the Heavenly Desolate Sword was here. There is only one chance, only success and no failure, Chu Duan has great confidence.

Take a deep breath and begin to throw the metal into the green steel fire.

The first step is to refine the essence of the metal and fuse the various essences to form a synthetic metal.

The second step is to start quenching the synthetic metal and casting it into a sword embryo.

The third step is to temper the sword embryo into a real sword.

There are no special requirements for the appearance of the Heavenly Desolate Sword, and it can be cast according to personal preferences.

Because the Heavenly Desolate Sword is born to carry the Heavenly Desolate Sword Yuan, the Heavenly Desolate Sword Yuan is different from the ordinary Sword Yuan, and it is difficult for the Wang Pin Sword Weapon under normal circumstances to exert the true power of the Heavenly Desolate Sword Yuan.

These metals are not ordinary metals, and it is not a simple matter to melt them at the temperature of green steel fire.

It took two hours for Chu Duan to melt all the more than a dozen pieces of metal, extract the essence from them, mix them together according to the order and method recorded in the Heavenly Desolate Sword Codex, and finally pour the mixed metal essence liquid into the inverted mold to form the shape of a sword embryo.

Wait until the sword embryo is solidified and take it off, put it into the green steel fire and roast, make the sword embryo red inside and out, put it on the iron felt, and start to beat.

This is also for the reason why to become a sword-casting master, a sword-casting grandmaster, etc., you need to carefully study the sword-casting Dafa, and you need to spend time and hard practice.

Zhenshan Jin instantly shakes and tempers the sword embryo, instantly exerts the strength through the mountain, enters the inside of the sword embryo, and internally tempers the sword embryo, so that the internal and external combinations are combined to continuously remove the impurities in the sword embryo.

First, he vigorously hammered dozens of times, and the shape of the sword embryo changed little by little, and then, Chu Duan changed to a smaller Xuantie hammer to hammer, and the strength of the hammer was more than half less than just now.

Now, the shape of this Wang Pin sword weapon is basically completed, and the next step is the process of carving.

The little Xuan Iron Hammer struck the sword body quickly and briefly, gradually changing the sword body to the shape that Chu Duan had in mind.

This is a very delicate work, and it is not something that can be knocked and beaten casually, and it must be integrated into the skills of the Tianzhen Rongyuan Sword Casting Dafa at all times.

Time passed little by little, and the muscles on Chu Duan's body continued to bulge and contract as he swung the Xuaniron Hammer, and the sweat glistened under the light of the green steel fire, as if it had been smeared with a layer of oil.

Three hours passed, and the sword under Chu Duxuan's iron hammer was almost formed.

Beat again and again, beat until it is almost cooled down, and then put it into the green steel fire and roast it red at high temperature, continue to beat, and so on and so on.

After another hour passed, Chu Duan suddenly exerted his strength and vigorously struck the sword with a small black iron hammer, making a piercing sound, turning into sound waves and vibrating away, like ripples in the water clearly visible.

Dropping the Xuantie Hammer, Chu Duan plunged his sword into the cold spring to quench the water, and a sneering sound sounded, and a large amount of white smoke curled up, filling the surroundings.

A quarter of an hour later, the sword cooled down, and Chu Duan pulled it out of the cold spring water, held the hilt of the sword in his right hand, and held it horizontally in front of him, examining it carefully.

The shape of the whole sword is the shape of the eight-sided Han sword on the earth.

The eight-sided Han sword looks majestic and majestic, there is an invisible domineering, upright, it is Chu Duan's favorite sword, on the earth, Chu Duan uses the eight-sided Han sword that the famous swordsmith tailor-made for him.

The sword accompanied him for many years, until he died.

In the past, Chu Duan didn't know how to forge swords, and he didn't have time to forge swords, so he got what sword to use and what kind of sword, but now, he can forge a sword by himself, or forge the most suitable sword for himself, so he naturally wants to cast the shape he likes.

The length of the sword is 110 cm, the hilt is 25 cm long, the sword grid is 8 cm long, the blade is 77 cm long, the width of the sword blade is 3.2 cm, 2 cm near the tip of the sword, and the width is 0.8 cm.

As for the weight, because the density of the dozen or so metals is very high, far better than ordinary steel, and after extracting the essence of it, it is constantly tempered, and the density is higher, and the weight reaches more than 100 catties.

Of course, the weight of more than a hundred catties was nothing at all for the physical strength that Chu Duan had now, just like a strong adult holding a branch.

There are four sides on each side of the sword body, showing a faint golden yellow, with countless lines on it, like feathers and clouds, like an ancient world, faintly about an ancient aura emanating out, which belongs to the fluctuations of the heavenly desolate qi.

The blades on the left and right sides of the sword body are not golden yellow, but a very obvious blood red, extremely thin, flashing with an astonishing edge all the time, extremely powerful.

And the tip of the sword, which also has an extremely fine scarlet light, seems to be restrained, and it seems to be about to erupt.

People who have cultivated to the Yuan Extreme Realm do not dare to look directly at this sword weapon with both eyes, because the edge is too strong, so strong that their vision power is unbearable.

Eight-sided Heavenly Desolate Sword!

With a slight wave, the extremely sharp blade seemed to cut through the void, leaving a bloodshot that was difficult to see with the naked eye, and disappeared in the blink of an eye, Chu Duan stabbed out with a sword, as if piercing the void in front of him, and the incomparably sharp sound sounded, and in an instant, Chu Duan could now stab a sword beyond the speed of sound.

"Good sword. The voice of the Shura Sword King sounded, and the body of the divine soul did not appear.

"It's a good sword. Chu Duan also nodded, and the middle finger of his left index finger was put together on the sword body of the Eight-sided Heavenly Desolate Sword and slowly stroked: "It is still the top Wang Pin sword weapon, and it is extremely powerful." ”

"Your sword-forging Dafa has already embarked on its own path. The Shura Sword King groaned and said, "But now you are only preliminarily becoming a grandmaster, and the road to a great grandmaster is still far away. ”

"Great Grandmaster, I don't have extravagant expectations. Chu Duan said.

The Sword Casting Grandmaster casts the Wang Pin Sword Weapon, and the Sword Casting Grand Master casts the Imperial Sword Weapon, that is, a powerful sword weapon suitable for the use of Sword Saint level powerhouses, and there is a great difference between the Wang Pin Sword Weapon.

Now it is the second time that Chu Duan has cast a Wang Pin sword weapon, because of the materials and his own sword casting Dafa, he has cast a top Wang Pin sword weapon, which is enough for him now.

At the very least, when he became a Sword Venerable and a Sword King, this eight-sided Heavenly Desolate Sword was enough for him to use for a long time, and as for achieving a Sword Saint in the future, let's consider the Imperial Sword Weapon.

"With your current entry, you can break through to the Yuan Extreme Realm within half a year, and when the time comes, your strength will increase by leaps and bounds. "Shura Sword King Dao, although he rarely speaks in the past year, he knows very well that Chu Duan's progress is much faster than when he crossed the Nine Transformations Realm in other years.

The Shura Sword King really wanted to accept Chu Duan as a closed disciple and teach him Shura Swordsmanship, but unfortunately, Chu Duan had his own ideals and goals, and between his words, he also revealed the idea of not wanting to worship him as a teacher, and the Shura Sword King could only retreat, but Xiao Qianfeng's talent was indeed very good, and it was completely okay to become his disciple.

"After the eight-sided Heavenly Desolate Sword has been cast, next, I will cast a scabbard. As he spoke, Chu Duan took out some more metal and melted it again.

The casting of the scabbard was not so difficult, and after two hours, Chu Duan finished casting the suitable scabbard, put it into the space wrist wheel, and left the sword casting room. (To be continued.) )
