Tianshan cold iron is a very precious casting material, and its disadvantage is that it is very difficult to melt and cast.

In the past, it was impossible to melt the cold iron of Tianshan Mountain without long calcination.

It is difficult to melt even, so casting is naturally extremely difficult.

Since Long Yin dared to ask He Hanyu to find the cold iron of Tianshan, he naturally had a method of melting and casting. This method is naturally to use the magic array of sun body refining to melt and cast the cold iron of Tianshan.

Nine times of Taiyin body refining have been completed, and the next will naturally be nine times of Taiyang body refining.

However, the magic array for the sun's body refining is to gather the power of the sun. The easiest way is to gather the domineering sun true fire.

The true fire of the sun is a very terrifying flame. What Long Yin is most worried about is the dangers he encounters when refining his body.

Don’t burn yourself to ashes if the sun’s body refining is not completed by then.

Now taking advantage of the opportunity to cast a sword, he is going to use Tianshan cold iron to test how powerful the sun's true fire is. If it is too powerful, he will probably have to carefully consider it if he wants to complete the sun's body refining.

Before starting the sword casting, the first thing he had to make sure is that the witch power in the Dantian was sufficient.

The last battle in the Soul-Breaking Valley consumed all his wizard power.

After taking a lot of Qi-nourishing Pills, he began to accumulate witch power.

After two days, half a drop of wizard power was gathered, and he began to consider the process of making a sword.

Just in the room, the Sun Huiyuan magic array was carved, and then the Sun Huiyuan magic array was activated with wizard power.

Then, he used the Taiyin sword energy to cut the cold iron of Tianshan Mountain and prepared to cut 20 to 30 kilograms per piece.

The Taiyin sword energy, which was originally unsatisfactory, was like cutting leather when cutting the cold iron of Tianshan Mountain.

Although it can still be cut, it is much more laborious than cutting other things.

It took a full quarter of an hour to finally cut off a piece of Tianshan cold iron the size of a rice bowl and then put it on the Sun Huiyuan Formation.

What made Long Yin frown was that the Sun Huiyuan Formation seemed to be helpless with this piece of Tianshan cold iron, as if it could not be melted.

Long Yin is very strange. Could it be that the Sun Convergence Formation is not good?

He pondered for a moment, transformed the witch power into the power of the Taiyin, wrapped one of his hands, reached towards the Sun Huiyuan Formation, and personally experienced the power of the Sun Huiyuan Formation. Even the cold iron in the Tianshan Mountains could not be melted, so he should not be able to burn his hand, right?

However, as soon as his hand reached the Sun Huiyuan Formation, he suddenly felt like one hand was reaching towards the stove.

Then, a force full of vitality and extremely hot energy penetrated into his hand.

When this force encountered the power of Taiyin in the arm, the two forces suddenly fought fiercely, and immediately turned into a millstone, tempering Long Yin's body.

Long Yin was shocked and hurriedly retreated his hand.

When I looked at his hand again, it turned red, as if it was burned.

Gradually, the power of the sun and the sun canceled out each other in his palms, and then the skin slowly returned to its normal color.

After carefully examining his palm, Long Yin found that not only did his palms have no problems, but were unexpectedly good.

At this moment, he finally felt relieved.

Although the sun will suffer incredible pain when refining his body, it should not burn his body. He can start the next step of refining his body.

Moreover, after the sun refining body, there should be huge benefits.

Because even after a little tempering just now, his palms had a meaning of yin and yang transformation.

If the whole body is successfully refining the sun, his body should have a strong reaction.

After determining one question, the second question made Long Yin very confused.

Because he wanted to melt the cold iron of the Tianshan Mountains. Now the Sun Convergence Formation does indeed gather the power of the Sun, but it cannot melt the cold iron of the Tianshan Mountains. How can this sword be cast?

Looking at the Tianshan cold iron above the Sun Huiyuan Formation, Long Yin pondered for a while and suddenly realized.

Because the Sun Yuanhe Formation mainly gathers the power of the sun, not the gathering of the true fire of the sun or the true fire of the sun, but is just another reaction of the Sun Yuanhe Formation gathering the power of the sun.

Now he is setting up the Sun Crown Array in the room, and there is no direct sunlight at all. How can he gather the true sun fire?

After understanding this truth, he immediately brought Tianshan Han Iron to the yard, drew the Sun Huiyuan Array under the sunlight, and then activated the Sun Huiyuan Array.

The winter sun shouldn't have much temperature.

However, when the Sun Catching Yuan Formation was activated, the sunlight in the yard seemed to be attracted by the Sun Catching Yuan Formation, and it was very strangely gathered on the Sun Catching Yuan Formation.

What's even more amazing is that it's like the starry sky coming from the distant starry sky late at night, the lights of the stars flashed on the Sun Huiyuan Formation.

These light spots are very small, probably smaller than dust, but the brightness is very bright.

Seeing this situation, Long Yin hurriedly clamped the Tianshan cold iron with fire tongs onto the Sun Huiyuan Formation.

The fire tongs had just reached into the Sun Huiyuan Formation and immediately turned into iron and then evaporated. The cold iron of Tianshan Mountain, which was originally difficult to melt, gradually became softer like dough, and finally turned into a red pool of iron.

Even this pool of molten iron is still evaporating, and the molten iron is getting smaller.

Long Yin was shocked. The power of the sun's true fire was far beyond his expectations.

If the sun's true fire continues to be refined like this, there will probably be very little cold iron left in the Tianshan Mountains.

But facing the terrifying Sun Fire, he didn't dare to reach out.

He hurriedly removed the Sun Conveyor Formation and used witchcraft - flowing water, allowing the pool of iron to form a sword embryo that was more than two feet long with his control.

When the sword embryo was formed, he immediately used witchcraft - Frost Descend. With a "spit" sound, the sword embryo cooled down and white mist rose in the yard.

Long Yin picked up the sword embryo, looked at something like an iron ruler, and couldn't help but laugh.

This first time, it was obviously unsuccessful to cast a sword, but he was already satisfied to be able to make the Tianshan cold iron into such a shape.

Then, the Sun Cluster Formation was portrayed for the second time.

This time, he did not rush to activate the Sun Conveyor Formation, but opened the ice jade stone.

Cut one-third of the ice jade, then cut a small piece of copper block next to it, and finally cut the silver-white metal into the size of a broad bean.

"Tianshan cold iron, ice jade, dense copper, and Taiyi Gengjin cast a sword, which is simply cheap! But this sword is a trial. When I succeed in the trial, the second sword will be the target of my real construction."

Long Yin was cruel and placed a few extremely precious materials on the Sun Huiyuan Formation.

These materials are completely beyond the value of He Hanyu's help.

He now looked like seeing how powerful the sword made from these four materials is...
