"That's right, is there any way to do it?"

Du Feng is not otherwise, anyway, when he comes to the stage to compete, he will be exposed sooner or later. At the moment, the most important thing is to spend as few contribution points as possible to improve the quality of the Dragon Sword. Because buying a good new weapon requires a lot of contribution points, it is not as cost-effective as directly improving the Dragon Sword.

In addition, this dragon sword is spiritual, and he will never throw it.

"There is something called Gengyuan, senior brother must have heard of it. ”

Zhao Shixiong knows a lot, in fact, Du Feng has never seen or heard of Gengyuan. It's not enough for him to know Gengjin, and it is estimated that Gengyuan must have a connection with Gengjin. Fortunately, Zhao Shixiong did not wait for Du Feng's answer, but went straight down.

Gengyuan is a precious metal aid, which is itself a powder and cannot be used to forge weapons. However, it can be doped with other metals to enhance toughness and hardness. Under normal circumstances, a warrior buys a little Gengyuan, and when he is forging a sword, he can improve the quality of half or one level.

But there is also a problem with using Gengyuan, that is, it cannot be used a second time. Next time, if you want to re-smelt this weapon, do it again. Then you have to scrap the previous Gengyuan, first rewind to the original grade, and then re-upgrade, the final result is still the same, which is equivalent to tossing once.

This is true for normal weapons, but this is not the case with growth-ready weapons. Because the Chenglong Sword is not re-smelting, but directly absorbs Gengyuan. It's like a human warrior who eats an elixir will absorb and use it, and next time he takes a new elixir, he doesn't need to spit out the old one.

Generally, medicinal materials are sold by catties, and metal minerals are often sold by jun, and a thousand catties are sold as a jun. But Geng Yuan's thing is about selling two or even money. A penny is only one hundredth of a pound, so you can imagine how precious this thing is.

After Du Feng figured it out, he took Zhao Shixiong into the Shuojin Pavilion, and first glanced at the high-grade innate spirit weapons and the best innate spirit weapons, which were really expensive. Maybe others are willing to use high-grade innate spirit weapons to go head-to-head with the second-layer sword leader, and it's a big deal to come back and reforge it.

But Du Feng was reluctant, he planned to at least upgrade the Dragon Sword to the best innate spirit weapon this time. He has already figured out the price of Gengyuan, one hundred contribution points for one tael, to put it bluntly, it is a small bit of golden powder. There are also people who spend ten contribution points to buy a penny, which is as little as a grain of millet.

Tut-tut...... It's expensive, but it's a good thing.

As soon as he saw Geng Yuan, before he could buy it, the swordsman in the dragon sword became excited. He estimated that he only needed to swallow another three taels of Gengyuan to be promoted to the best innate spirit weapon.

Because in the sword tower before, some iron filings of the sword people had been absorbed, and now it is really not too bad. Du Feng thought about it, so he just spent three hundred contribution points first and exchanged them for three taels of Gengyuan.

"Yo, it's new, it's a lot to contribute. ”

The person in charge of the exchange is a young brother, not an inner disciple, nor an outer disciple, but a staff member of the Yuxian Sect. The sect is also full of masters and disciples, and there are also some workers who are not just for practicing but just for making money and living.

Du Feng's disciple's waist card is new, because there is a number on it, and it can't deceive people. However, in such a new disciple's waist card, there were two thousand six hundred and two contribution points, which immediately aroused the interest of the staff. As soon as he shouted, the rest of the staff came over to see.

"Wow, more than two thousand contributions are so stingy, buy a sword. ”

"This brother, let me tell you, it's useless to upgrade low-grade weapons, it's better to buy high-grade ones directly. ”

In fact, the staff is telling the truth, low-grade weapons can only be upgraded once when they are promoted to medium-grade with Gengyuan, or medium-grade weapons are promoted to high-grade, and they will be wasted when they are used up. But if you buy a high-quality weapon directly, it can be used in a high way. If you want to improve next time, you can use Gengyuan to upgrade to the best. The best innate spirit weapon is comparable to a low-grade magic weapon, and it saves too much money than buying a magic weapon directly.

"You don't have to worry about it, Senior Brother Du already has high-grade weapons. ”

Before Du Feng could speak, Zhao Shixiong raised his head and licked his face. He didn't mention the matter of riding the dragon sword, but just said that Senior Brother Du already had a high-grade innate spirit weapon.

"Oh, that's okay, that's okay. ”

The staff is also kind-hearted, since there is a high-grade innate spirit weapon, it is indeed worth spending three hundred contribution points to be promoted to the best. If you want to be more powerful, then you have to spend money to buy a low-grade magic weapon first, and then upgrade to a medium-grade magic weapon. However, the price of magic weapons is too high. And it's not under their control, wait to go to the second floor to find the hall master to exchange.

"Thank you!"

Although the staff's opinions were not used, Du Feng still thanked them. I paid three hundred contribution points with my disciple's waist card, and I successfully exchanged it for three taels of Gengyuan. After getting it, it was thrown directly into the small world of necklaces.

"What a good thing to eat, I want it too. ”

Seeing Geng Yuan being devoured by the Dragon Sword, Xiao Hei was also greedy. Now that the white bone banner and the ghost servant have been left at the bottom of the mountain, it is really a little bored on its own.

"Just know how to eat, wait until I get back and see if I can exchange something for you." ”

Du Feng originally said something unintentionally, but his eyes swept over the table of contents, and he really swept one thing, Lei Tie. As the name suggests, thunder iron is iron ore that contains the power of thunder and lightning. It's a great way to craft a lightning weapon.

However, this thing is very expensive, and it takes a lot to build a complete sword. If it is not a martial artist with extremely high cultivation and excellent Lei qualifications, he will not choose to use this thing. If you buy a small amount for Xiao Hei to eat, it is a good choice.

Of course, Du Feng is talking about the future, after all, he is too poor now. Of the two thousand six hundred and twenty contribution points, three hundred have already been spent. The rest must be accumulated well, and before the year-end competition, I have saved enough 8,000 contribution points to exchange for a superb sword technique.

"Brother Du, let's talk about it. When you make a fortune, you must buy me thunder iron to eat. ”

Okay, Du Feng dug a pit for himself. Originally, Xiao Hei didn't look for Lei Tie here, but now he knows that he is hungry.

"Okay, as long as I get rich, I'll buy you everything. ”

Du Feng also hopes that Xiao Hei will be promoted soon, Lei Tie is not the same as the demon pill of the demon beast. Xiao Hei eats a limited amount of demon pills, which requires a certain amount of digestion time. Even if you eat at one time, you may not be able to promote the required amount. But Lei Tie is different, if you can eat a lot of it, it will definitely help it advance.

Just when Du Feng was chatting with Xiao Hei, good news came from Chenglong Sword's side, it had been successfully promoted.
