In the personal room of the three of them, looking at the black metal balls that were quietly suspended and wriggling in the stove, they could faintly feel the connection between the thing and themselves.

"The refining has almost reached its limit, and if it continues, it is likely to cause irreparable damage." The words of the three came, and only at this time did she feel less weak.

"This should be the next step!" As he spoke, he stretched out a hand and swiped it in the air, and a black opening appeared in mid-air, and then he reached in and took out a man-tall object from it, like an enlarged version of an ancient key.

This is the first time that Bai has killed the Heroic Lich in the [Mobilization Order] of the Heroic Lich in the first multiplayer dungeon, the [Key of Hades]!

Description: A peerless staff created by a powerful lich with the power to communicate with the underworld!

Bai hasn't used this weapon since he got it, although he has thought about using this as a hole card, but it's not convenient to carry, so he kept it in his personal room until he got the [Storage Box], and didn't carry it with him until he got the [Storage Box].

However, since it didn't take long for him to obtain the [Storage Box], he never had a chance to use it, so he was placed until now and took it out again.

From the moment he got this weapon, Bai knew that this weapon was not suitable for him and could not be his core equipment, at most the above two additional skills, which could be used as hole cards.

At that time, he also thought about selling, but he was still very weak and didn't dare to sell it at all, but now, he found that he was not particularly short of gold coins, so he kept it.

Taking out this Noble Phantasm-level weapon today, of course, is to play its role, and it is likely that it will be used for the last time.

Because if you use it today, this weapon will disappear forever!

The casting of the magic sword is not so easy.

Under normal circumstances, the swordsmith itself has the strength of a hero or above, and it is impossible to forge a magic sword under a hero.

Of course, this is also normal.

It's not impossible to forge a magic sword under the hero.

Of course, it comes at a great cost!

And Bai wants to forge a magic sword, and the price he pays is this treasure-level weapon!

Any equipment item, after reaching the treasure, will undergo a huge change in nature, just like ordinary people to be promoted to heroes, they need considerable "performance"!

The performance here can be understood as "path", "ceremony", "merit", etc.

If a person wants to be promoted to a hero, he needs to do something that is recognized by many people, even the world consciousness!

To take the simplest example, if a brave man kills the Demon King, then he can be promoted to Hero through the "achievement" of "killing the Demon King", and at that time, he will receive the exclusive title of Hero, as well as the blessing of the corresponding domain.

This is one aspect of the promotion of justice, where there is justice, there is evil.

For example, if a person slaughters tens or millions of people in a city, then he is about to be promoted to a hero through the "achievement" of "slaughtering millions of people".

The same is true for the promotion of props, but the "performance" required for the promotion of props is easier than that of people.

For example, if a powerful magic weapon kills a heroic creature, then as long as you fill that weapon with some Noble Grade ore materials, then you can be promoted to Heroic Rank through the achievement of "Killing Heroic Creature".

This is also the regular forging method for most weapons such as magic swords, famous swords, and holy swords.

And in order to forge the magic sword, the "performance" chosen by Bai is "the reunion of the treasure-level props"!

The Noble Phantasm level in the props is equivalent to the hero level in the creatures, and it is no different from killing the hero level when it is integrated into other Noble Phantasm levels.

If you just use this tricky method to forge, it will make people feel very lost!

After all, in order to forge a treasure-level weapon, to destroy another treasure-level prop, and to add various other materials, is obviously much higher than the cost of conventional forging.

But Bai and they are not qualified to carry out regular forging, so they can only choose this loss-making method.

"Take it!" He handed the [Key of Hades] in his hand to the three, and there was no change in the expression on his white face.

Maybe in the eyes of others, this is a loss-making business, but in his opinion, it is not a loss, it is very cost-effective to use a high-level weapon that is more chicken for himself, plus some materials, for a high-level weapon that is suitable for him.

The three turned out to be the [Key of Hades], and there was only regret in their eyes.

Destroying a treasure-level equipment is a distressing thing for someone like her who loves forging, but the thought that a magic sword will be born from her hand soon, she immediately became excited.

After rubbing the Key of Hades in her hand for a while, she threw it into the reluctant stove, and then quickly adjusted the power of the stove to turn it on to the maximum.

The Key to the Underworld was suspended in the space of the furnace, and under the influence of a certain force, rust began to slowly appear, and then fell off, repeatingly, as if it had been rapidly sped up.
