The rust disintegrated very slowly, and it took more than three hours to stare at the stove before the [Key of Hades] lost the shape of the key and became tattered.

Over time, after five hours, the useless impurities were completely removed, and the furnace was left with only a mass of brass-colored molten metal and a cloud of gray gas.

At this point, the [Key of Hades] has completely collapsed and officially disappeared from this world!

"It's time to start merging." As if reminding, the three said a word, and then concentrated on the operation.

First of all, the brass-colored metal liquid, just like the previous refining, let it flow into the main cavity and come into contact with the refined sword embryo.

At the moment of contact, the two masses of molten metal reacted violently and immediately began to boil.

The three of them immediately began to get nervous, although they were nervous, but they were not flustered, she quickly moved and threw neutralizers into it, and under the continuous vaporization and consumption of neutralizers, the reaction slowly calmed down.

"I've finally calmed down." The three of them breathed a long sigh of relief, to be honest, she was nervous and anxious just now, for fear that something would go wrong.

Now, under the action of neutralization, the reaction of the two masses of molten metal is neutralized and begins to gradually fuse.

At this time, the flattening rate of the neutralizer slowed down somewhat.

Shiro glanced at the reaction in the furnace and the remaining crystalline minerals as neutralizers, and frowned slightly.

"Three, isn't there a bit of a neutralization thing?" Shiro asked.

After hearing this, the expression that was originally a little nervous also changed slightly, and she immediately turned her head to look at the crystal minerals left on her right, and then looked at the reaction in the furnace, frowning and quickly calculating in her heart.

As she calculated, her cheeks gradually lost their blood, and cold sweat continued to break out on her forehead.

"Brother Xiluo, what should I do? It really doesn't seem to be enough! She looked anxious, with a hint of crying in her voice, and her eyes full of self-reproach and panic.

"Looking at what is left now, it should still be able to support it for a while." Bai frowned and said, "How much more do you need, I'll buy some more while I still have time." ”

"It also takes about two kilograms of this universal neutralizing spar, but this kind of thing is not common, in order to forge the magic sword, I have scavenged almost everything on the market before, and I don't know if there are so many after these few days." The three said anxiously and helplessly.

"Is there anything else that can be replaced?" Shiro continued to ask.

"Yes, there is, but according to the nature of different species, I can't calculate how much is needed, and if it is not a complementary mineral, even if it is barely used, it is very likely to form impurities and reduce the quality of the magic sword after it is formed!"

"That's better than a complete failure!" Bai Zhengse said, "What do you need, tell me quickly!" ”

The three of them were startled by Bai's sudden voice, and suddenly changed back to their original weak temperament: "That's right...... I'm sorry...... As long as it is a cold ore material......"

"Cold nature...... a flash of light suddenly flashed in Bai's mind, and then he quickly took out a black crystal that was only the length of a finger from the [Savings Box] and asked, "Is this okay?" ”

It's the Infernal Ice, a Noble Mineral-level mineral material obtained in the previous dungeon.

After the three took it, their eyes suddenly lit up, and the whole person became excited, and even said to Bai in a somewhat reproachful tone: "Brother Xiluo, why didn't you take out such a good thing earlier!" If I had taken it out earlier, I wouldn't have had to work so hard to collect the Universal Neutralization Crystal! This piece is enough to support the neutralization consumption required for the forging of the entire magic sword! ”

"No! Gotta tweak, or it will be a waste of this Hellice! As he spoke, the three of them began to adjust on their own, completely leaving Shiro's existence behind.

Watching her constantly adjust the stove, although I don't know what she is doing, there is a lot of change in the stove.

I saw that the half-fused metal liquid in the furnace actually began to separate, and not only that, but as time passed, the clusters of metal balls of different colors also separated.

When all the metal was separated, the three immediately threw the Hellice into the furnace.

As soon as the Hell Ice entered the furnace, a white mist appeared on the surface, like ice cubes that had just been taken out of the refrigerator in the summer.

The white mist that floated out of the prison ice slowly split into several streams, drifting towards the few clouds of metallic liquid, and being absorbed by them.

At this time, the three of them moved again, and she immediately controlled the metal liquid to begin to fuse again, and at the same time did not forget to ask Bai for a few test tubes of blood to pour into it.

This time, the fusion was much smoother than the previous few days, and the molten metal of the group almost did not react, and the fusion was completed at the moment of touch, and the prison ice was also rapidly consumed at the same time, and the volume continued to shrink.

Time passed little by little, and under the control of the three, all the metal clusters fused together, and the color changed greatly.

Although it is still black overall, if you look closely, you will see that the black is mixed with a hint of cyan and blood-colored stripes, and the stripes flutter like ribbons in the metal liquid, which looks very magical.

The Hellice wasn't completely consumed, and there was only a piece the size of a fingernail left, swirling around the liquid metal like a satellite.

"In the end, that's it!" The three muttered to themselves and immediately began the final steps.

In the furnace, in addition to the metal liquid and a small piece of Hell Ice, there was also a gray air mass, which was the "achievement" that was decomposed from the [Key of Hades]!

Now this final step is to let the newborn magic sword devour this "performance" and form a new performance to be promoted!

Carefully controlling the "performance" close to the metal liquid mass, as the distance between the two continued to shorten, the faces of the three began to turn pale, and sweat broke out on their foreheads, as if they were being tortured, and their faces gradually became hideous.

Just when there were about ten centimeters left between the two, the three suddenly stopped moving, then let out a long breath, and immediately collapsed to the ground.

Seeing this, Bai immediately took out a bottle of stamina recovery potion and fed it to her, and then her complexion slowly became ruddy.

"Thank you for your hard work." Bai thanked her very sincerely.

After hearing this, the three were stunned at first, and then showed a smile, probably because of the recovery of physical strength, and there was a slight red rhyme on their cheeks, and said: "It's not hard or hard, just help Brother Xiluo!" ”

Bai nodded, then took out three feathers with golden flames, handed them to her, and said, "This one is for you, it can save your life when it is critical." ”

The three of them were not pretentious, and after receiving the sound [Healing Feather], a trace of surprise flashed in their eyes, and then they quickly put it away.

Looking at the situation in the furnace, the "performance" had begun to be slowly absorbed by the metal liquid, and the three said: "Judging from the current situation, in about 10 days, the forging of the magic sword will be completed!" ”

Hearing this, Bai nodded.
