Is this spiritual weapon, is its characteristic to break the ban? That's a nice feature. Although Ning Fan can also break the ban by issuing the forbidden talisman himself, and he also has to consume his own spiritual power, but he can use the forbidden talisman all the time.

For example, some large-scale prohibitions that are far away, or prohibitions that require several places to break the ban together, at this time, it is not something that can be solved by the ban-breaking charm. Besides, if a spiritual weapon with this characteristic is taken out and sold, it will also be sold at a good price.

In many missions, especially secret realm exploration and treasure hunting missions, there will be a lot of prohibitions and formations, and if you have such a sword in your hand, the probability of success will be greatly improved.

What a spiritual weapon! It's a pity not a sword.

Most of the inheritance and skills that Ning Fan has obtained are related to swords, and "Yilong Thunder Light Sword" itself is a comprehensive inheritance based on swords, without a sword, it is impossible to exert its power at all, so what Ning Fan urgently needs now is a spirit sword, not an iron pimple.

Ning Fan decided to refine a sword, a spirit sword with a forbidden function.

But before that, there is a question that must be thought through, how did this steel lump here break through to more than ninety refinements?

From the refining techniques to the steps, there is not much difference from before, even the materials are ...... Wait, the material, there seems to be something different on the material.

During this refining, Ning Fan remembered that he added a little bit of Mithril to the molten iron, could it be that it was because of this little Mithril that he made a breakthrough in the method of refining?

It's not impossible to think about it, after all, there must be a reason why this Mithril can be so cherished.

Whether it is or not, you have to try it to know.

Take out a piece of wrought iron again, and then melt it away, becoming a mass of molten iron, at this time Ning Fan added a little bit of Mithril again, the amount is only a little more than last time, Ning Fan's idea is that since Mithril is easy to use, then more of it.

Like the steel lump before, Ning Fan still processed this piece of wrought iron step by step according to the technique of hundred refinements: hammering, folding, heating, and hammering again.

After this was carried out in the eighty-first refining, Ning Fan was relieved, because he saw that this wrought iron had already become steel at this time, and it could continue to be refined downward, and its interior had also opened into four regular veins.

This time, starting from the eighty-second time, when Ning Fan folded it, he deliberately folded it into a long strip, gradually approaching the direction of the sword.

Refining nine times in this way, to ninety-one times, equaling the record of the steel lump, at this time, the shape of the hundred refining steel is already very close to a sword, if you stop at this time, and then temper it on the edges and corners, I believe that a spirit sword can be refined.

However, Ning Fan didn't stop, he wanted to take another step to improve and really make this material into a hundred steel, he wanted to see what a real spirit weapon made of a hundred steels looked like.

With such determination, Ning Fan continued to temper. At this time, the first tempering took a lot of effort, and it could take an hour before and after, and just like that, in the afternoon of this day, Ning Fan had completed the ninety-third tempering.

At this time, this piece of material is not far from Bailian, the hardness and toughness have reached a very strong degree, and there is a faint cold light flashing on it, if it is processed into a sword at this time, it must be a very strong sword, and it can definitely be regarded as a low-level spiritual weapon.

But Ning Fan was not satisfied, he wanted to try the hundred refinements, he wanted to know if he could reach the hundred refinements now.

So he began the ninety-fourth tempering, and then, he failed, and the piece of steel finally broke.

As soon as it is broken, it is broken from the middle, and the four veins at the very core are destroyed in two places at once.

But fortunately, although it was broken this time, the mouth was very neat and broken into two slender strips.

Ning Fan thought about it, and based on these two slender strips, he continued to refine and process, refining into two spirit weapon swords.

Although there is only one vein within each one, this vein can also be entered into the talisman array.

Ning Fan didn't immediately enter the rune array into the sword, but stopped and thought, why did it break this time? Is it really impossible to refin, or is the method wrong, or is the material not good?

In the end, Ning Fan came to two conclusions, one may be that there are some problems in the folding method, and the other may be that there are problems in the material.

The folding square test taken by Ning Fan before has always been folded in half, such a folding method, although the middle part of the sword is very hard and tough after many folds and repeated forging, but the side is not necessarily so strong, and the whole sword is not even, and the folding to a certain extent is too strong due to the hardness of the sword, which is likely to break the material and more likely to destroy the internal vein structure.

On top of the materials, Ning Fan thought that Mithril was a little less.

So next, Ning Fan came up with another tempering plan, one is to add a little more Mithril at the beginning, and the other is to start trying a new folding method, three-layer folding, after the seventy-two tempering is completed.

The so-called three-layer folding is to look at the material as three parts, the middle part does not move when folding, and the two parts are folded towards the middle. This folding method can not only evenly stress the whole material, but also keep the veins of the middle part of the village material from being damaged.

However, this attempt only reached the fifty-second tempering, and it failed, and the root did not have time to try a new folding method.

Ning Fan had to admit that this time the material was wasted. If something else is wasted, it's nothing, isn't it wrought iron? And much more! But Mithril was used in it, and it was used a lot this time, this thing was too precious, even Ning Fan couldn't afford to waste it.

The obvious reason for this failure is that Mithril has added too much. In fact, it has been said in the "Encyclopedia of Basic Materials" that if you add too much Mithril things, it will make the materials brittle. Ning Fan also knew this, but the previous two attempts made him see the benefits of Mithril and ignored this one.

This neglect leads to failure.

So, at the end of the day, it ended with a failure.

Seeing that the expiration time of the cave mansion was one day closer, and there were only two days left in the qualifiers for the refining competition, Ning Fan had not yet refined a spirit weapon sword that satisfied him, which made him very anxious, so he didn't dare to stop at all, and immediately started the next attempt.

This time, he reduced the investment of Mithril, even less than the previous two times, and Ning Fan was not prepared to make any changes to the other trial plans.

Soon, the tempering passed sixty times, and there were no problems, Ning Fan put his mind at ease, and at the same time confirmed in his heart that the previous attempt was indeed Mithril's problem.

Continued, and soon came to the seventy-second time, so far, there is still no problem, the veins of the four laws have been formed in the material at this time, and the material itself is also very tough at this time, which is a good basis for continuing to try.

At this time, of course, Ning Fan wanted to continue, but at this time, it was not the original folding method, this time, he wanted to try a new folding method.

This time, he carried out it carefully, after all, it was a new method.

It worked, it didn't take much effort, and the seventy-third time it was very simple.

Ning Fan didn't dare to be careless, and while continuing to try, he always paid attention to the changes in materials. After eight more attempts, reaching the eighty-first time, Ning Fan found a problem at this time: under the three-layer folding of this material, it was to avoid the middle part being folded too much, but to make the middle part thinner again and again with the continuous folding.

If this continues, it may eventually destroy the four veins in the middle of the material.

After thinking about it for a while, Ning Fan had a way: since it is not possible to fold only to one side, then fold it on another side.

It's a simple matter of turning the material upside down and folding it. The eighty-second tempering, Ning Fan folded and tempered on the opposite side, and it was easy to do it.

Not only that, Ning Fan also had a pleasant discovery, he found that inside the material, there seemed to be two more veins.
