Well, it's really not that easy to leave the magic city tonight.

Du Feng first picked up a piece of purple spar and took a look, this thing was extremely cold to start, and it felt that it could freeze people's finger joints. Most people hold it in their hands because it is too cold and it sticks immediately. Fortunately, Du Feng understands magic skills, and he transports demonic energy to his hands to constantly cool down his hands.

When the temperature of the hand is about the same as the purple spar, or even cooler than the spar, it will naturally not be sticky.

Good thing, Du Feng pinched it with his fingers and tried it, this purple spar is very hard. If there are large pieces, you can use them as weapons by polishing them directly. But now it's all small pieces, and it's impossible to polish them directly into a sword.

How can such a hard thing be fused together and cast into a sword that meets the standards?

Du Feng decided to study the furnace first, maybe this furnace has some different functions. He tried to inject demonic energy into the furnace, and soon purple flames appeared in the furnace. The flame was not hot, but very cold. Through the hearth, you can feel the chill inside.

Interestingly, in the past, Du Feng used a high-temperature furnace to melt ore, and then forge various weapons or armor. Today's furnaces are strange enough to rely on the cold to melt the hedrons. The greater the amount of demonic energy injected, the more abundant the cold energy inside becomes, and the more vigorous the cold fire will naturally burn.

He had figured out that these purple crystals were melted by the cold fire in the furnace. Then, from the track next to it, the melted crystal water is drawn out and flows into the sword embryo grinder.

Now that you've figured it out, let's get to work. Du Feng didn't rush to throw all the purple spars into it at once. Instead, they were thrown in one by one, and when they saw that one was almost melted, they threw it in the next moment. The amount of demonic energy injected is also controlled within a certain amount of power, so that the furnace does not exceed its control.

He often observed the situation in the hearth, and when he saw that the amount was not even equal, he stopped filling it with purple hedrons. His hands continued to inject demonic energy into the furnace, making the cold fire in the furnace burn more and more. Those purple crystals are transformed into deep purple crystals. After the continuous burning of the cold fire, some impurities were slowly discharged.

Ordinary ores, after high-temperature calcination, will burn some impurities into a gaseous state and then volatilize away. And these purple spars are even more scorched at low temperatures. There are some impurities that will be frozen into a gaseous state and then volatilized. It's just that those gaseous states just now volatilized in the furnace, and the air quickly condensed into solids.

Therefore, Du Feng must constantly clean up the volatilized impurities, so as not to affect the effect of forging.

When there were no more impurities volatilizing, Du Feng knew that the time had come. He immediately channeled the crystal water out and let it flow into the sword embryo grinder. Since this crystal is liquefied in extremely cold conditions, it will naturally solidify when heated up.

So the process of cold quenching of ordinary weapons becomes hot quenching here. Du Feng was originally able to manipulate the immortal fire of the Feng clan, and as his cultivation grew, the power of the immortal fire would also increase. So he just kept spraying immortal fire on the sword embryo, causing it to quickly condense into solid.

Then he took it to the forging table and began to forge it repeatedly with a sledgehammer. When the forging is almost done, it is returned to the furnace to make it semi-soft, and then taken out to continue forging. This repeated forging process can make the sword body continue to be compressed, and the material density will increase as a result, and the sword body will naturally become stronger.

Jingle and keep busy until dawn, and a purple translucent crystal sword is finally completed. There is one last step left, and that is to enchant it. Infusing demons and injecting spirits have the same meaning, the only difference is that what is injected is not the true element but the demonic energy.

Du Feng does not lack demonic energy, what he has is still authentic heavenly demonic energy. Streams of Heavenly Demon Qi were injected from the hilt of the sword, and the purple crystal sword was activated. The current situation of demonic qi injection directly affects the smoothness of launching demonic skills when using the sword in the future.

Du Feng didn't dare to be careless, meditating on the three styles of Xuan Ming in his heart, and at the same time constantly restraining the demonic qi inside. The mental method of the three forms of Xuan Ming naturally affected the flow of demonic energy inside the amethyst sword body. This flow mode can form a special vein. And this vein, that is, the dark lines on the sword body. I can't usually see it, but I can show it as soon as I get lucky.

"That's it!"

When it was done, Du Feng handed the Amethyst Sword to the female demon cultivator. This sword has been forged into a superb magic weapon, but in fact, it can't be used with the cultivation of the female demon cultivator at present.

Du Feng doesn't care so much, he just tries to forge the best thing under the existing materials and conditions. As for whether the female demon cultivator can use it, then it is her own business. Even if you can't use it now, you can use it if you have it. A high-level weapon is better than a low-level weapon.

"You are really a talent, should you consider coming to the Demon Realm to develop? I can ask my grandfather to introduce you to the Six-in-Eight Desolation Demon Troupe, which will definitely be good for you. ”

The female demon cultivator's eyes lit up with the newly created amethyst sword, this sword was really good, even better than she imagined. Du Feng was in business, knew the formation, and sold the elixir he refined, and now he had personally created a sword in front of her. This kind of talent is really not to be missed.

"When I have the opportunity in the future, I will go to the Demon Realm, but not yet. ”

Du Feng didn't refuse bluntly, because he wasn't the kind of person who was jealous and hateful when he mentioned demon cultivation. After all, he himself practiced magic skills, and he got along well with some friends in the demon world. Last time I was in the Dark Cloud District, there were many demon cultivators who regarded him as their backbone.

"Well, if you go, remember to join the Liuhe Eight Wilderness. ”

Originally, Du Feng was not interested in this Liuhe Eight Desolations, but the female demon cultivator repeatedly mentioned it, so he asked what kind of organization this so-called Liuhe Eight Desolations was.

This question doesn't matter, the so-called Liuhe Eight Desolations of the Demon Realm turned out to be an organization similar to the Heavenly Realm Adjudicator. They have a high level of adjudication power and can dispose of others at will. That is to say, in the Demon Realm, as long as the Liuhe Eight Desolation Arrangement feels that someone is guilty, then someone will be sent over to kill him. No matter what kind of big family head or what big sect head is, they don't save face.

Tut-tut...... I didn't expect that there was such an organization in the Demon Realm, and listening to this meaning, I still met the conditions to join it. You must know that in the Heavenly Realm, no one has ever invited Du Feng to join the adjudicators. In fact, he was very interested in the adjudicators, and if he had the chance, he would like to join in and take a look.
