The appearance of the Hydra made Star Rail Ayutthaya take the situation in the Mountain Castle very seriously.

On the sixth day after the end of the siege of the fish-man, a gray sculpture with wings of more than 20 meters appeared above the mountain castle, this gray sculpture had a delicate house, which looked like a small mobile palace, and when the gray sculpture fell, six men and women walked down the house.

Viscount Xiao Luo, who had already received the news, saw a middle-aged man led by the six, and hurriedly stepped forward to greet him: "Welcome Lord Guardian of the Clouds." ”

Wang Cheng had already understood the identity of this middle-aged man when he saluted Viscount Xiao Luo.

One of the guardians of the Star Rail Great City, a real star refiner, a hundred-story tower in the direction of the City Lord's Mansion is his residence, and the two men and three women behind him are all his disciples, and these people have star power fluctuations emitting from them, obviously they are all people who have stepped into the star refiner level.

Viscount Xiao Luo and Star Refiner Youyun were chatting about something, and after chatting for a while, Youyun turned his gaze on Wang Cheng and walked towards him.

"Wang Cheng, this is Lord Youyun, Lord Youyun is very curious to learn that you killed a fishman warlock and got a staff of the fishman warlock, he has been studying the secret method system of the fishman warlock, and wants to know the source of the power of the fishman warlock to release the secret method, and is interested in buying your staff. ”

Viscount Xiao Luo, who was accompanying him on the side, hurriedly introduced.

"The staff?"

Wang Cheng thought of the deadwood-like staff when the fishman warlock performed the secret technique, and he couldn't see anything unusual about that thing, so he just said, "Lord Youyun can take it if he wants." ”

"Heh, Wang Cheng is it, you are very good, it is said that you have not only killed a fish-man warlock, but also killed two seriously injured fish-man kings, in terms of your current cultivation, it is very remarkable, but I will not ask for your things in vain. ”

The middle-aged man Youyun chuckled: "The market price of the fishman warlock's staff is around forty star stones, Youyun." ”

"Forty Star Stones!"

Wang Cheng was shocked.

The Fishman Warlock's deadwood-like staff was so valuable, not inferior to inferior astral weapons?

At this time, behind the middle-aged man, a female star cultivator of about twenty-three or fourteen stepped forward, took out four fluorescent star stones from a small bag on his body and handed them to Wang Cheng.

"It's ......"

"Wang Cheng, why don't you go and get the staff and send it to me, I'll be waiting for you in the living room. ”

Viscount Xiao Luo looked at the four star stones in Wang Cheng's hand, a trace of envy flashed in his eyes, and he hurriedly urged.

Although Wang Cheng didn't know why the woman named Yuya gave him four star stones, he still nodded and left quickly.

In the elevator, he pondered that everyone's expressions were not abnormal, and a high-ranking star refiner would not swallow that staff for the sake of forty star stones, but he faintly guessed something.

Thinking to himself, he had already reached his floor, entered his room, and turned the staff out.

And at this time, Wang Xuanji, who was cleaning up in his room, saw the four star stones in Wang Cheng's hand, and couldn't help but exclaim: "Ah, this is a medium-grade star stone?"

"A higher-grade currency?"

Wang Cheng, who happened to be unable to confirm his guess, set his eyes on Wang Xuanji.

"Yes, the medium-grade star stone is indeed a more advanced currency, the external ratio is one to ten, but the purchase price on some markets often reaches an astonishing one to eleven, if it is a large exchange, it is also possible to exchange one hundred medium-grade star stones for one thousand one hundred and fifty ordinary star stones! This level of star stones, but the currency that star refiners will only choose when they trade in large quantities, Ah Cheng, where did you get the four medium-grade star stones?"

"One-to-ten or one-to-eleven-five?"

Yu Aya had just handed him these four star stones before, but he didn't feel anything.

After all, four medium-grade star stones are far from having the same strong visual impact as forty ordinary star stones, and with his current ability, it is not difficult to obtain three or four star stones, but now that he heard Wang Xuanji's explanation, such four star stones can really be exchanged for forty or even fifty ordinary star stones, and his gaze at this star stone suddenly became cautious.

"With four star stones, you can buy a star weapon?"

"Four medium-grade star stones can not only buy a star weapon, but also a star weapon with good effects among the low-grade star weapons. ”

Wang Cheng stared at this star stone, he couldn't see how this star stone was different from ordinary star stones, it was nothing more than that the starlight inside was a little richer......

Starlight?

Wang Cheng's heart moved, and he said, "You judge the grade of the star stone by the starlight in this star stone?"

"That's right, the biggest difference between the medium-grade star stone and the ordinary star stone is that the starlight in the medium-grade star stone is much stronger than the starlight of the ordinary star stone, and the starlight of the ordinary star stone circulates in the star stone, while the medium-grade star stone has a weak brilliance even if it is placed at night. ”

Wang Xuanji said, looking at the four medium-grade star stones in Wang Cheng's hand full of envy.

If she also had a medium-grade star stone at the time......

With only one piece, she didn't have to withdraw from school, and her brother Wang Lian wouldn't go deep into the barren land to make up for her tuition, thus losing his life......

"If there are medium-grade star stones, then there can be high-grade star stones, and what about the top-grade star stones? What is the ratio between them, and what is the difference?"

Wang Cheng asked.

He didn't want to make a joke about not being able to identify the grade of the star stone in the future.

"There are naturally high-grade star stones on the medium-grade star stones, and it is said that there are superb star stones on the high-grade star stones...... In terms of proportion, it is the same as ordinary star stones, the standard ratio is one to ten, a high-grade star stone is worth one hundred or one hundred and ten ordinary star stones, the biggest feature of high-grade star stones compared to medium grades is the color of the light, white with a hint of blue, like a bright moonlight, clear and charming, as for the peerless star stones on the top, I have also seen it by chance from the books and biographies of the Flame Academy, and I have never really seen it, I only know that the light circulating in it is no longer blue, but purple......"

Wang Cheng nodded.

Wang Xuanji is not valued in the Wang family, even if she has the five-fold cultivation of a martial artist, it is also the limit to be able to access the top-grade star stones, and it is reasonable not to know the superb star stones, after all, according to the exchange ratio, a superb star stone will have at least 1,000 ordinary spars, and according to the price fluctuation of high-grade star stones for low-grade star stones, this number will increase, even if it is finally exchanged for 1,200 or 1,300 ordinary star stones.

Such a number, let alone her, even the entire Wang family may not be able to come up with it.

"Wait. ”

Just as Wang Cheng was about to leave the room with the staff, his figure suddenly froze.

"Purple!?purple!?"

It was like a bolt of lightning flashing through his mind......

For a while, he couldn't even bother to send the staff to Viscount Xiao Luo's study, so he stepped forward and grabbed Wang Xuanji's shoulder and asked, "Purple? What is the purple? What is the depth? Is there any change in the appearance of the superb star stone and the ordinary star stone? Do you have any pictures of the superb star stone?"

Wang Xuanji saw that Wang Cheng was asking so eagerly, he didn't dare to hide it, and hurriedly said: "I don't know, what I saw at the time was only a text description, and I haven't seen the real picture, but there must be records of these things in the academy, Ah Cheng, if you want to know, or I'll go to the academy to have a look......"

Wang Cheng looked at Wang Xuanji.

The superb star stone is too far away for her, just like a mortal who doesn't know what a jade worth hundreds of millions looks like, and it is reasonable that Wang Xuanji can't answer.

At the same time, he also realized that his mood had changed too much, and quickly reined in his mind.

"No!"

At the end, he glanced at the staff in his hand and said, "I'll send the staff to the Cloud Star Refiner." ”

"Youyun Star Refiner?That's a famous big man in our Star Rail City, has the reinforcements finally arrived?Ah Cheng, Youyun Star Refiner is a truly great big man, don't be lazy, send the staff quickly, if you can please Lord Youyun and be accepted as a disciple by Lord Youyun, the door of the Star Refiner will almost be open for you. ”

Wang Cheng nodded, didn't say anything, and took the staff and headed towards Viscount Xiao Luo's study.

And in his mind, he was constantly thinking about a star beast blood crystal obtained from the journey of the royal family's caravan.

A purple star beast blood crystal that killed the life of a man surnamed Dong and buried half of the wolf thief group.

The wolf thief group judged that it was a mutated star beast blood crystal, but if it was really just a mutated blood crystal, the man surnamed Dong would feel confident that this thing could make it easy for him to enter the Flame Academy, and make himself and Qin Xuerou, Qin Tianji and other star refiner candidates alongside?

Could it be that the Wolf Thieves are mistaken?

If that purple star beast blood crystal was not actually a blood crystal, but a superb star stone......

Thinking of this, Wang Cheng couldn't help but feel suffocated.

......

"Wang Cheng, why did it take so long. ”

Soon, Wang Cheng came to Viscount Xiao Luo's living room: "Give me the staff." ”

Wang Cheng nodded and handed the staff to Viscount Xiao Luo.

Viscount Xiao Luo left with his staff, but he did not greet Wang Cheng, and Wang Cheng did not leave.

And Viscount Xiao Luo's departure was a full two hours.

It wasn't until two hours later that he seemed to have settled the group of Youyun Star Refiners, freed up his hands and feet, and returned to his residence, but when he was about to rest, he was stopped by Wang Cheng: "Viscount Xiao Luo, please stay." ”

"Hey, Wang Cheng, haven't you left yet?"

Viscount Xiao Luo was a little surprised, and after a while, he seemed to think of something: "You want me to introduce Lord Youyun to you?"

"I have plans at the moment, and I am not in a hurry about this matter. ”

Wang Cheng said, pretending to be stupid and said, "I want to ask, didn't Lord Youyun say that he was willing to buy that staff with forty star stones, why did he only give me four star stones?"

"You don't know?"

Viscount Xiao Luo was slightly stunned, but he quickly seemed to think of something: "You were an ascetic before, and it is reasonable that you don't know much about these common sense things, what Lord Youyun gave you is not an ordinary star stone, but a medium-grade star stone, although there are only four star stones in your hand, but if you are willing, I am willing to exchange forty-five ordinary star stones with you." ”

"Medium-grade star stones!?Is there still a grade of star stones?"

Wang Cheng pretended not to know and asked.

"Of course, there are still high-grade on the middle grade, there are superb products on the top grade, and the star crystal on the superb one, the high-grade star stone and the superb star stone can be exchanged for one hundred or one thousand ordinary star stones, and this number will only be high and not low, as for the star crystal, it is even more remarkable, a star crystal is 10,000 star stones. ”

"The superb star stone can be exchanged for a thousand ordinary star stones!? It's incredible!And the star crystal, I really don't know what the top-grade star stone, the superb star stone, and the star crystal look like!?"

"Haha, the exchange number I said will only be high and not low, if you want to take a superb star stone to exchange for an ordinary star stone, it is not difficult to change a thousand two, one thousand three, as for the star crystal, it is even better, as for the appearance, it is easy to distinguish very, I don't say anything about the medium-grade star stone, in addition to the fluorescence overflow, there is often a trace of blue inside, and the superb star stone has actually been called an inferior star crystal, which is crystalline, and there is more purple brilliance in it, and the style is ...... It's a bit similar to the Star Beast Blood Crystal, as for the Star Crystal, you don't need to ask, with your current identity, you can't get access to this kind of currency that the Great Star Refiners only use when they trade in large quantities. ”
