Although it took a long time to burn the ganwood to burst into pieces, this was still expected by Xiaofeng.

But what made him feel incredible was that the outer Ganmu burned out, but the filament was extremely heavy, almost equivalent to the weight of a Ganmu when it was born.

He couldn't help but secretly say, "Could it be that the weight of the sweet wood does not come from its ability, but from the filaments in the body of this tree?"

Feeling this, how could he not be suspicious.

At the same time, he was pleasantly surprised, and he was worried that it would be difficult to compress the gambush, but the most important thing in the gamber was not the trunk, but the filaments, and everything would be easy.

In his opinion, in order to forge the sword, it was only necessary to incinerate the filaments in the wood, so that they could be further calcined and fused, and then it would be considered a success.

But in order to confirm his thoughts, he threw another piece of sweet wood into the fire, and after nearly half an hour of burning, the sweet wood shattered again with a "bang" sound, leaving only a golden filament on the fire.

But before Xiaofeng could come back to his senses, the two filaments instantly fused together on their own.

Looking at its size, it has to be larger, and its weight is twice as much as before.

Seeing this, Xiao Feng suddenly rejoiced in his heart, because he knew that his chances of success at this time had been greatly successful.

At the moment, he reduced the intensity of the fire little by little until it was extinguished.

As the firepower continues to decrease, the filaments on the fire gradually lose their light, returning to their original appearance, and the weight is also lighter after the firepower is lost.

Seeing that the filament did not change after the fire was extinguished, Xiao Feng finally put his heart down for the most part, but even so, he still had to confirm another characteristic of it.

Immediately, I saw that his spiritual power was immediately released, and the floating filaments on the tripod flew into his hands.

Then Xiao Feng poured spiritual power into the filament, and after an instant, his eyes were full of surprised smiles.

Because after infusing the filament with spiritual power, it actually regained its original weight in an instant.

But at the same time, Xiao Feng felt a little disappointed, because this filament still sucked people's essence and energy.

Despite this, he was still overjoyed, because what he valued most was not only the weight of the liganwood, but more importantly, its ability to absorb the energy of human spirit.

As for how to make it not absorb the user's essence, Xiaofeng knew very well that this could only be done slowly. After all, what we have to do now is to forge the sword first.

Looking at the filaments in his hand, he began to calculate how many filaments De needed to forge a sword he needed.

As far as Xiao Feng was concerned, although the Lingyun Sword was extremely powerful, its sword body was too big.

Although you can usually hide it in your sleeve, if you carry it, you will need to spend spiritual power to support its weight at any time, and it will cost a lot of spiritual power.

However, if you can successfully cast this filament, even if you carry it all the time, it will not be a matter of effort.

After thinking about it for a while, Xiaofeng made a decision.

He decided to forge a sword about three feet long and three inches wide.

The reason why such a size was chosen was to make the sword look more delicate, but more importantly, it was to consider the materials needed and the weight of the sword.

Taking materials as an example, if you want to refine and cast a size like Lingyun, you will only need hundreds, or even thousands, of Ganmu squares.

But now that the Feiyun car is being built, what it lacks most is Ganmu, and Xiaofeng doesn't want to lose a big one because of a small one.

At the current size, no more than fifteen pieces of ganwood are needed.

In terms of weight, due to this size, there are more than a dozen ligans, and the weight of more than a dozen licotrees has reached millions of catties.

And with Xiao Feng's current cultivation, he was a little skeptical that he would be able to wield a sword of such weight.

However, he was confident that as his cultivation improved, it shouldn't be difficult.

On the other hand, if the weight of the casting is too light, if it can no longer be produced or found in the future, it is a matter of regret.

Therefore, after comprehensively considering the actual situation of all aspects, Xiaofeng finally determined the size of the casting.

Once he had made a decision, he didn't hesitate any longer.

An Nai's heart was excited, and he immediately got up and flew quickly towards Ganmu Forest.

When he came to the forest, he began to choose sixteen of the lower sweet trees according to his calculations, and he did not go anywhere else, but made a fire in the same place and began to incinerate them.

In the end, after two days and two nights of repeated burning, looking at the sword that had basically taken shape in the fire, Xiao Feng's heart was extremely happy, but his face was full of sweat.

He had expected that the weight of the sword forged from filament would be within his reach, but he did not expect that its weight would be far beyond his expectations.

But he was comforted by the fact that it was small enough to support most of its weight with the help of a tripod.

Rao is like this, he is still afraid that Ding will not be able to bear its weight, or consume a lot of physical strength to remove the weight of the sword.

In this way, the consumption of physical strength was unspeakable, and he had already taken the Huiqi Pill more than a dozen times before and after.

But fortunately, at this time, the sword had been formed, and Xiao Feng clearly felt that in a few moments, the sword he hoped for could be refined.

Just when his heart was filled with infinite anticipation, the cloudless sky suddenly surged, and huge dark clouds blocked the scorching sun, and the sky and the earth were dark.

Seeing this, Xiao Feng was shocked: "Could it be that casting this sword will also attract thunder?"

Suddenly, his heart couldn't help but feel heavy.

Even though a long time had passed, he was still afraid of the thunder that Lingyun had attracted back then, not to mention the situation when he was refining the True Spirit Pill.

Since the process of refining and casting Ganmu Wusi was quite smooth, there was no abnormality on the way at all, but at this time, looking at the posture on the head, it seemed that the end was coming.

Thinking of this, Xiao Feng couldn't help wiping a handful of sweat, and hurriedly played two lines of protection to protect him and Ding, and at the same time, at the same time, Ling Yun stepped aside, and all the cold sun golden needles were released.

Just as Xiaofeng was thinking, the dark clouds above suddenly changed.

I saw it spin rapidly, forming a huge vortex in the sky, and the vortex was as black as ink.

Xiao Feng was suddenly shocked: "It's not good! If he is allowed to volley into the air, then this piece of Ganmu will not be destroyed in one fell swoop." ”

Thinking of this, he immediately released all his strength and rushed towards the sea with Baoding in his arms.

As soon as I came to the beach, I could only hear a loud "boom" in the sky.

Immediately, the vortex pulled its long tail and carried a huge thunderbolt to shoot downward.

"Boom ......"

With a loud bang, the thunder fell on the sea ten feet away from the wind.

Its tremendous energy stirred up a huge amount of water, and the waves rushed in all directions, lapping against the protection of the small wind.

At the same time, the waves of the sea rushed to the shore in a few breaths, slamming the shore.

Seeing this scene, Xiaofeng couldn't help but secretly say, "It's really dangerous"!

But after just breathing, his smiling face sank again.
