As we all know, spiritual weapons are also divided into four categories: Heaven and Earth Xuanhuang, and the common one is the yellow level.

The Xuan level is very precious, and it is often only possessed by large families, and the number is not much.

And if it is a ground-level spiritual weapon, it will be even more exaggerated, I am afraid that everyone will scatter all their wealth to snatch it, and even those hidden families who do not go out will also appear and join them! Because there are so few of them!

As for the heaven-level spirit weapon...... It was cut off as early as a thousand years ago, because it took a heaven-level refiner to refine a heaven-level spirit weapon, and it also needed the best materials, and these have long been extinct on the mainland, and no one has a chance to see them, so the heaven-level spirit weapon has become a legend and will not appear again at all.

It's not impossible to upgrade the grade of the spirit weapon, but it's very troublesome, it's almost equivalent to rebuilding the spirit weapon back to the furnace, and with this kung fu, you can almost recreate a spirit weapon, unless this spirit weapon is particularly meaningful to the owner, no one will be willing to do it.

"Spiritual liquid is a thing of the past."

The Gu family patriarch seemed to know that this name was very unfamiliar, so he explained:

"It is said that thousands of years ago, there were still heaven-level refiners at that time, and this spiritual weapon liquid was developed by them, as long as the spiritual weapon was soaked in it for seven hundred and forty-nine days, it could make it jump by one grade, but this method can only be used for the promotion of yellow-level spiritual weapons to Xuan-level."

And something like this?

Although it can only improve the yellow-level spiritual weapon, this is already very shocking, after all, there are so many yellow-level spiritual weapons, with this spiritual weapon liquid, wouldn't it be possible to transform a large number of Xuan-level spiritual weapons?

The Great Elder and the others breathed for a while, and their eyes were hot.

"But the production of this spiritual weapon liquid is extremely difficult, it needs to be fused with nearly a hundred kinds of materials, and the amount of each material is extremely harsh, if you make a slight mistake, you will fail, if you use it on the spiritual weapon at that time, let alone improve the grade, even the original good spiritual weapon will be destroyed."

Patriarch Gu sighed lightly, and sighed with emotion, "This spiritual artifact liquid is a thing that is against the sky, think about it, the materials used in each spiritual weapon are different, and even the attributes are different, such as some ice attributes, some fire attributes, but now there is a medicinal liquid that can be applied to all spiritual weapons, which sounds shocking!" ”

"Thousands of years ago, its price was extremely high, but later with the disappearance of the heaven-level refiner, no one mastered this method, and after a long time, even its formula could not be found, so the spirit liquid has become a legend."

If it weren't for him, as the patriarch, who had turned over a lot of books in the clan, I am afraid that he would have never even heard of it like everyone else.

"Heh, what about the artifact liquid? Could it be that you want to say that what Gu Yifeng booked from you is this spiritual liquid? The second elder laughed, his eyes full of mockery.

"Why not?" Su Caiyin raised her eyebrows.

"It can't be!" This was said by the patriarch, and he shook his head without thinking about it, "There is no such thing in the world, let alone the spiritual liquid, if you can come up with the formula, it will be a sensation on the mainland!" ”

The patriarch had read the book, so he knew the preciousness of the spiritual artifact liquid, and because of this, he didn't believe that Su Caiyin would have this thing in his hands at all.

Everything that has become extinct, but you say you have it, whoever believes it is a fool!

And in the patriarch's opinion, Gu Yifeng is that fool.
