"How much is a catty?" Fang Yuan reached out and picked up a smaller piece of meteorite iron, about a little larger than an ordinary potato, estimated to be more than a dozen catties.

"Usually we sell 1,200 spirit stones a catty, and here is the head of the Fang family, we give a nine-percent discount. The shopkeeper said.

"Thank you, Master Fang, although I really want to buy it, it doesn't seem that there are enough spirit stones. Is there a smaller one?" Fang Yuan felt a little sweaty.

Nima, a cultivator, was forced to be speechless by the spirit stone, and this life is really ......

Fang Yuan was so far away that it was not that he really didn't have any spirit stones, but that he had to have a certain reserve of spirit stones in case he needed them urgently.

"There is no ordinary meteorite, but there is still a piece of black meteorite in our store, weighing 3 catties and 7 taels, but the price needs 1500 spirit stones a catty. The shopkeeper said.

"Brother Fang, I don't know why you bought meteoric iron?" asked Xiang Kuijin.

"I want to refine a magic sword. Fang Yuan told the truth, he just kept the news of refining the high-grade magic sword secret.

"If it is refining a magic sword, this black meteorite is more effective than ordinary meteorite. Xiang Kuijin said.

"That's good, it's also troublesome for Boss Kuang to take it out and take a look. Fang Yuan calculated, the price of less than 4 catties of black meteorite iron was within 6,000 spirit stones, which was exactly in line with his plan.

This is actually the difference between refining a high-grade magic sword by yourself and buying a standard magic sword. Fang Yuan successively purchased three military array knives in the system, which were low-grade magic weapons, middle-grade magic weapons, and high-grade magic weapons. And the price of a top-grade magic weapon is only 1200 spirit stones.

In the market, if you buy a high-grade knife or a high-grade magic sword, its price is also between 1000-1500 spirit stones. But now, Fang Yuan wanted to refine the magic weapon by himself, and the auxiliary material Black Meteorite Iron alone needed nearly 6,000 spirit stones.

This price difference is likely to be unbelievable to many people.

Of course, Fang Yuan could also do without this black meteorite.

But for Fang Yuan or any of the foundation building monks, how could they use magic weapons that were openly sold in large quantities on the market? In that case, when fighting with fellow foundation building monks, others would most likely design for the weakness of their magic weapons, and perhaps without a few moves, the wielder of the magic weapon might die.

This is not a threat, but a real situation. Ordinary standard ritual instruments have such problems.

But if you refine it yourself, that is, the sword in the world, it is a unique sword, then it will not be easy for others to find the weakness of the sword. In addition, monks with wealth and goods like to add some special materials to the magic weapon, which makes the magic weapon have some special functions.

Even if they are both high-grade magic weapons, the effects of the two are absolutely worlds apart.

If the monk makes up his mind, he can also make a magic weapon with various special materials into a life weapon, which is usually used for the temperature difference in the dantian, and can be taken out against the enemy at critical moments.

Fang Yuan wasn't sure if he could refine the natal artifact that suited his mind now, he had to prepare the materials first before thinking about how to refine it.

The Black Meteorite took it out, and it looked like an irregular egg, really only the size of a small ping-pong egg.

"Tell the host, please take this piece of material!" Suddenly, the upgraded system passed a message to Fang Yuan.

Fang Yuan's face changed. What the system wants to intervene in must not be as simple as it seems.

"Fang Daoyou, could it be that this piece of black meteorite iron is not to your liking?" Seeing Fang Yuan's performance, the shopkeeper asked cautiously.

"Hehe, where. I'm thinking, this innate everything, how can it be so different! It's the same meteoric iron, why are some red and some black? ”

"It is said that when this black meteorite fell from the sky, its flames and smoke escaped into the interior of the meteorite, that is, this meteorite was fully tempered by the heavenly fire. That's why it's about half more expensive than ordinary meteorite. ”

"I see. Shopkeeper Kuang, how much is it?" Fang Yuan thanked him, then took out the storage bag from his waist, and almost at the same time, Fang Yuan transferred the large amount of spirit stones in the system to the storage bag.

"This piece of black meteorite iron is 3 catties and 7 taels, 1500 spirit stones per catty, a total of 5550 spirit stones, the head of the Fang family can give 5500 spirit stones in person. "The shopkeeper Kuang gave a fraction of the discount.

"Okay, just follow the shopkeeper. Fang Yuan gave the money neatly, picked up the black meteorite iron and left the [Iron Mountain Immortal Material Trading Company]. Of course, the moment he put the Black Meteorite into the storage bag, the thing had actually entered the system warehouse.

In the past month, Fang Yuan has studied the system a lot.

The existence of that system warehouse is really too convenient. Everything can be put in the storeroom, and it is very easy to access. As soon as Fang Yuan's divine sense invaded the storehouse and wanted to move his divine sense, that thing would come out. It's much more convenient than storage bags and Qiankun rings.

Of course, in order to hide people's eyes, Fang Yuan's storage bag also had to be maintained, and some odd things or a small amount of spirit stones were placed in it. In case of defeat, the storage bag and Qiankun ring can also be "golden cicada shelling".

At this time, as soon as Fang Yuan returned to Fang Mansion, the system reminded: "Congratulations to the host, you have purchased a fifth-level material at the price of a second-level material, and it is an extremely scarce fifth-level material. ”

"Level 5 material, what is this?" Fang Yuan communicated with his divine sense.

The system sent a lot of information.

These materials were not available in the books that Fang Yuan had already read.

This fifth-level material is called "planetary nucleus", also called the most basic "star core". It usually grows in the interior of a planet, and is the essence and core of a planet's survival.

The reason why the planetary core exists alone is that the planet explodes, the planet is blown open, and the star core is sputtered in all directions in the form of high-temperature meteorite, and the planetary core is scattered in the universe; When there is life on the planet, the latter's behavior is unprecedentedly brutal.

In immortal cultivation, the second-level material is already called the spiritual material, and the fifth-level material is the higher-level spiritual material. Although the planetary core is only a fifth-level material, its price sometimes catches up with the seventh-level material, mainly the planetary core, the number of which is a fixed number in a universe, if you want to find another planetary core, from the beginning of the universe to the planetary core can be used, I don't know how many billions of years.

In short, this material is available but not sought.

Among the materials related to Fang Yuan's consumption of the planetary core, Fang Yuan's mind came up with special requirements for the planetary core refiner.

Just as soon as he saw this special requirement, Fang Yuan knew that he wanted to use the planetary nuclear refiner this time, and he was afraid that he wouldn't be able to. Because if Fang Yuan stubbornly wanted to use the planetary core at this time, it would be tantamount to destroying the heavens.

The planetary core is the material for refining high-grade spiritual weapons, and at this time, Fang Yuan can only refine high-grade magic weapons, this is not a tyrannical thing, what is it!!

But this weapon, Fang Yuan had to refine.

Therefore, Fang Yuan had to bite the bullet and buy a piece of ordinary meteorite iron, and then add it to the materials of refined iron and red copper.
