In the secret room, Zhang Hao looked at the front quietly, and Feng Zhiling was looking at the Xuantie in his hand with greedy eyes.

This Feng Zhiling is really a bit unreliable, he received a lot of Xuan Iron from Zhang Hao, but he has never started refining the flying sword.

It wasn't until after so many things happened last night that the refining began.

Of course, there is also a little reason for Zhang Hao, until this morning, Huang Mingshan and others made a kilogram of 99.9% pure black iron.

It's just that after Feng Zhiling saw this Xuantie, he called it impossible. Then I kept looking at it, and my eyes were full of amazement.

Zhang Hao didn't speak, just looked at this unreliable senior brother.

One kilogram of 99.9% black iron is only, and since a technological breakthrough has been made, the Zhang family can produce more - this is the advantage of technology. So for Zhang Hao, this kilogram of 99.9% dark iron is nothing even if he is greedy by Feng Zhiling.

If a kilogram of iron can verify a person's heart, it is worth it!

Yes, this is also a test of Feng Zhiling by Zhang Hao.

Zhang Hao watched quietly, Feng Zhiling was still boasting.

After a while, Feng Zhiling suddenly looked up at Zhang Hao and admired: "Senior brother, it's amazing, it's really amazing." I have seen the Xuanzhen Sect master get a piece of 99.7% Xuaniron, and it is very precious, and he will say it when he meets people. Then, he was shunned away by a certain elder, and he didn't have a good face for a month. Haha......"

Zhang Hao sighed, "99.7% Xuantie, is there anything special?

"The magic weapons and spiritual weapons refined by Xuantie are the easiest to refine, which is incomparable to other spiritual materials. Darkiron seems to be the closest to the human body.

Moreover, among the common spiritual materials, dark iron, red copper, mythril, and pure gold, dark iron is the hardest and sharpest. ”

Zhang Hao listened, silently wrote down this information, and asked: "Since Xuantie is so good, why is red copper and so much more expensive?"

"There are many reasons. On the one hand, there are red copper, mythril, pure gold, etc., each rarer than the other. Secondly, it is more difficult to obtain more than 90% purity of dark iron, while it is easy to obtain more than 90% purity of red copper, mythril, etc.

There is also pure gold, most of which is inherently pure and elemental with a purity of more than 90%.

In addition, although the dark iron is hard, the ability to transmit aura is significantly weaker than that of red copper.

Oh...... Another point, Xuantie's compulsion is a little lower. Haha......"

Zhang Hao: ......

Feng Zhiling laughed, and casually threw the Xuantie, and the Xuantie was suspended in the air. Feng Zhiling kept taking out various items from the storage ring.

Zhang Hao's eyes were opened. Feng Zhiling's storage ring seems to have everything. But most of the items, which are magic weapons, are very small when they are taken out, and they are quickly enlarged.

For example, a fist-sized 'iron block' is quickly enlarged into a forging table of about 1.5 meters.

Feng Zhiling looked at Zhang Hao's eyes and was very proud: "No way, the storage ring space is limited, so it can only be like this." ”

Zhang Hao frowned slightly: "The storage ring space is limited, didn't the senior brother bring a few more?" I heard that there is also a storage belt, which can be built into several storage spaces?"

"Yike...... How do you know I have a storage belt? I've transferred what I need to the storage ring in advance, how did you find out? You won't ...... Voyeurism, right?"

Zhang Hao: ......

Feng Zhiling's subordinates didn't stop, and took out a black gourd and put it under the forging table. Blowing on the gourd, a purple flame suddenly emerged from the mouth of the gourd.

Under the forging table, there was a flame formation arranged with a high-grade spirit stone, and after the flame formation was triggered, a faint purple flame surged up, forming a raging fire.

The billowing heat soon made Zhang Hao's head sweat. This kind of flame is very peculiar, it seems to be not only scorching, but also can cause the restlessness of the true element in the body, making Zhang Hao only feel irritable in his heart and unbearable heat in his body.

Feng Zhiling looked at Zhang Hao and smiled: "Senior brother, this is the unique fire of the Xuanzhen Sect, the Zixiao Heavenly Fire. Ranked 12th among known fires.

The magic weapon refined with Zixiao Heavenly Fire can give full play to the characteristics of spiritual materials by 180%, and can refine the evil qi and filth in spiritual materials.

I don't know how many people want the Xuanzhen Sect's Zixiao Heavenly Fire Refiner, but they can't ask for it. ”

Zhang Hao's body was hot, and he exerted his curiosity: "Senior brother, what is a different fire?

"That's a good question. Refining weapons, including alchemy, require special flames. The most common one is 'real fire'. It is the flame spawned by the cultivators of the Jindan period, who use the Jindan cultivation as the foundation and practice a specific exercise.

Generally, the Jindan stage true fire refiner can only exert six or seven percent of the spiritual material.

The real fire in the infancy period can play eighty percent.

There is also the flame that uses the demon pill of the demon beast to spawn. Because the types of monsters are different, the flames are also different. This kind of flame is called 'demon fire'.

Some demon fires are comparable to different fires, and some demon fires are not as good as the real fire of the Jindan period. And so on.

Most of the common low-level refining tools on the market are refined with ordinary demon fire, and the special properties of spiritual materials are exerted. So the price is low.

Finally, there are different fires, and there are many different fires, and the power and effect are also different, and they are very different. ”

"As for refining weapons, the above-mentioned flames must be used, whether it is true fire, demon fire, or different fire. It is only after the calcination of these flames that the properties of the spiritual materials can be stimulated. ”

At this time, under the calcination of Zixiao Heavenly Fire, the Xuantie bloomed with a shining treasure light, and the treasure light flowed on the surface of the Xuantie like flowing water.

Feng Zhiling stopped talking, and he began to pound while holding the Xuantie with fire tongs. The black iron gradually took on the shape of a sword, only a little rough.

Having almost finished forging the blade, he sat down cross-legged again, took out his tools and began to cut the surface of the blade. The tools are flying around, like butterflies, and there are treasures flickering from time to time, and Feng Zhiling's hands are busy, and the scene is very beautiful.

The body of the sword gradually became smooth, beautiful, and agile, and a little pattern appeared on the body of the sword - that was the formation.

Feng Zhiling's face was serious, and his subordinates did not stop.

Time passed little by little, and more than two hours had passed inadvertently. The true element in Zhang Hao's body gradually subsided, and the restlessness gradually disappeared. He was already attracted by Feng Zhiling's serious and busy appearance.

Forging a magic weapon flying sword is by no means a simple matter, the formation has to be carved little by little, Zhang Hao doesn't know how many formations Feng Zhiling has depicted, only look at his hands waving clearly, the surrounding files, chisels, shovels, cones, etc. are constantly flying, and the sonorous sound is endless.

The Zixiao Heavenly Fire has never been extinguished, and the flying sword needs to be heated when it cools slightly, and it is always in a red-hot state.

Feng Zhiling, who works hard, does have a bit of the demeanor of a senior brother and a master in the world.

After another two hours, Feng Zhiling's face began to turn a little pale, and sweat appeared on his brows. He kept his hands on his hands, turned his head to the side and took a deep breath, and a pill flew directly into his mouth.

For more than half an hour, the flying tools gradually fell, and Feng Zhiling picked up a piece of silvery-white metal the size of a fingernail from the side. That's the star gold.

The Star Essence Gold gradually melted into an incandescent liquid under the calcination of the Purple Sky Fire, and Feng Zhiling carefully controlled it, the incandescent liquid rolled on the surface of the flying sword and along the formation, leaving a faint mark where it passed.

(I heard that rolling and then asking for a ticket is the right posture~)
