The appearance of the nine headed monster made the orbital City pay great attention to the situation of the mountain castle.

    On the sixth day after the Yuren siege, a gray sculpture with wings over 20 meters appeared over the mountain castle. On this gray sculpture, there was an exquisite house that looked like a small mobile palace. When the gray sculpture fell, six men and women walked down the house.

    When Viscount Xiao Luo, who had received the news earlier, saw a middle-aged man headed by the six people, he hurried forward to meet him: "welcome to the guardian of Youyun, your excellency."

    Wang Cheng knew the identity of the middle-aged man when he saluted at Viscount Shaw.

    One of the guardians of the star track City, a real star refiner, whose residence is a hundred story high tower in the direction of the city master''s house, and the two men and three women behind him are his disciples. These people all have the occasional fluctuations of star power, which are obviously people who step into the star refiner level.

    Viscount Xiao Luo and Youyun, the star refiner, were talking about something. After a while, Youyun turned his eyes on the King City and walked towards him.

    "Wang Cheng, this is Lord Youyun. Lord Youyun was very curious when he learned that you killed a fishman warlock and got a staff from the fishman Warlock. He has been studying the fishman warlock''s secret method system. He wants to know the power source of the fishman warlock''s secret method and wants to buy your staff."

    Viscount Xiao Luo, who accompanied him, hurriedly introduced him.

    "That staff?"

    Wang Cheng thought of the dead wood staff when the fishman warlock performed his secret arts. He couldn''t see anything unusual about it. He just said, "Lord Youyun wants to take it."

    "Oh, King City? You''re very good. It''s said that you killed not only one Mermaid warlock, but also two seriously injured Mermaid kings. In terms of your current cultivation, it''s great, but I won''t take your things for nothing."

    The middle-aged man Youyun chuckled: "the market price of the fishman warlock''s staff is up and down the forty star stone, Youling."

    "Forty star stone!"

    Wang Cheng was surprised.

    The fishman magician''s staff like a dead wood is so valuable that it is not inferior to the inferior star ware?

    At this time, behind the middle-aged man, a female star refiner up and down came forward, took out four fluorescent star stones from a small bag and handed them to Wang Cheng.

    "This is..."

    "King City, go and get the staff and send it to me. I''ll wait for you in the living room."

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

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

    In the elevator, he thought that everyone looked normal, and a high star refiner would not swallow that staff for the sake of the forty star stone. He guessed something.

    He thought that he had come to his floor, entered his room and turned out the staff.

    At this time, Wang Xuanji, who was cleaning up his room, saw the four star stones in Wang Cheng''s hand and couldn''t help exclaiming: "ah, is this a middle-grade star stone?"

    "Zhongpin Xingshi? A more advanced currency?"

    Wang Cheng, who just couldn''t confirm his guess, turned his eyes to Wang Xuanji.

    "Yes, Zhongpin Xingshi is indeed a more advanced currency. The external ratio is 1:10, but the purchase price in some markets often reaches an amazing 1:11. If it is a bulk exchange, it is also possible to change 100 Zhongpin Xingshi to 1150 ordinary Xingshi! This grade of Xingshi is the currency that the star refiner will choose when dealing in bulk, Acheng , where did you get the four middle grade star stones? "

    "One to ten or one to eleven five?"

    Youling had just given him these four star stones, but he didn''t feel it.

    After all, the four middle-class star stones are far from as strong a visual impact as the 40 ordinary star stones. With his current ability, it is not difficult to obtain three or four star stones. But now, according to Wang Xuanji''s explanation, these four star stones can really be exchanged for 40 or even 50 ordinary Star stones. He suddenly became cautious when he looked at this star stone.

    "So four star stones can buy a star ware?"

    "The four medium quality star stones can not only buy one star, but also have good effects among low-level stars."

    Wang Cheng stared at this star stone. He couldn''t see the difference between this star stone and ordinary star stone. It was just that the starlight inside was rich

    Starlight?

    Wang Cheng moved in his heart and said, "do you judge the grade of the star stone through the starlight in the star stone?"

    "Yes, the biggest difference between Zhongpin star stone and ordinary star stone is that the starlight in Zhongpin star stone is much stronger than that of ordinary star stone. The starlight of ordinary star stone flows in the star stone, and even at night, Zhongpin star stone has weak brilliance."

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

    If she had Zhongpin star stone at that time

    With only one piece, she doesn''t have to withdraw from school, and her brother Wang Lian won''t go deep into the barren land in order to collect her tuition and lose his life

    "If there is a middle grade star stone, can there be a top grade star stone? What''s the ratio and what''s the difference?"

    Wang Cheng asked.

    He doesn''t want to make a joke that he can''t recognize the star stone grade in the future.

    "There is naturally a top-grade star stone on the top-grade star stone. It is said that there are top-grade star stones on the top-grade star stone... The proportion is the same as that of ordinary star stones. The standard proportion is 1:10. A top-grade star stone is worth 100 or 110 ordinary star stones. The biggest feature of the top-grade star stone compared with the middle-grade star stone is the color of light. There is a trace of blue in the white, which is like bright moonlight, clear and charming , as for the top-notch star stone, I have seen it by chance from the books and biographies of flame college. I have never really seen it. I only know that the light flowing inside is no longer blue, but purple... "

    Wang Cheng nodded.

    Wang Xuanji doesn''t receive much attention in the Wang family. Even if she has five levels of cultivation of martial arts, her access to top-grade star stones is also limited. I don''t know that top-grade star stones are reasonable. After all, according to the exchange ratio, a top-grade star stone will get at least 1000 ordinary crystals. Moreover, 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 1200 or 1300 ordinary star stones, it is not difficult.

    Such a figure, let alone her, may not be available to the whole Wang family.

    "Wait."

    Just as Wang Cheng was about to leave the room with the staff, his body suddenly gave a meal.

    "Purple!? purple!?"

    It was like a flash of lightning in his mind

    For a moment, he couldn''t even send the staff to Viscount Xiao Luo''s study. He came forward and held Wang Xuanji''s shoulder and asked, "purple? What purple? How deep? Are there any changes in the appearance of excellent star stones and ordinary star stones? Do you have a picture of excellent star stones?"

    Wang Xuanji saw that Wang Cheng was so eager to ask and dared not hide it. He hurriedly said, "I don''t know. What I saw at that time was only a text description, but I didn''t see the real pictures. However, there must be records about these things in the college. A Cheng, if you want to know, either I''ll go to the College..."

    Wang Cheng looks at Wang Xuanji.

    The top-grade star stone is too far away for her. It''s like a mortal doesn''t know what the jade worth hundreds of millions looks like. It''s reasonable that Wang Xuanji can''t answer.

    At the same time, he also realized that his mood changed too much and quickly converged.

    "No!"

    Finally, he looked at the staff in his hand and said, "I''ll send the staff to Youyun star refiner."

    "Youyun star refiner? That''s a famous person in our star track city. Has the reinforcements finally arrived? A Cheng, Youyun star refiner is a really great person. Don''t neglect it. Send the staff quickly. If you can win the favor of Lord Youyun and be accepted as a disciple by Lord Youyun, the door of the star refiner will be almost open for you."

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

    But in his mind, he was constantly recalling the blood crystal of a star beast from the journey of the king''s caravan.

    A purple star animal blood crystal that killed the man surnamed Dong and buried half of the wolf theft group.

    The wolf stealing 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 it could make him light and easy to enter the flame college, and make himself tied with Qin Xuerou, Qin Tianji and other star refiners on the waiting list?

    Will the wolf robbers admit their mistake?

    If the purple star beast blood crystal is not actually a blood crystal, but a unique star stone

    Thinking of this, Wang Cheng couldn''t help breathing.

    ……

    "Wang Cheng, why did it take so long?"

    Soon, the king came to Viscount Shaw''s living room: "give me the staff quickly."

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

    Viscount Shaw left with his staff, but he did not greet the King City, and the King City did not leave.

    And Viscount Shaw left for two hours.

    It was not until two hours later that he seemed to have settled the Youyun star refiner and his party, freed up his hands and feet and returned to his residence. However, when he planned to rest, he was stopped by the King City: "Viscount Xiao Luo, please stay."

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

    Viscount Xiao Luo was a little surprised. A moment later, he seemed to think of something: "do you want me to introduce Lord Youyun to you?"

    "I still have plans. I''m not in a hurry."

    Wang Cheng said and pretended to be a fool: "I want to ask, didn''t you Yun say that he was willing to buy the 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 soon seemed to think of something: "you were a ascetic. You didn''t know much about these common sense things. It''s reasonable that Lord Youyun gave you not an ordinary star stone, but a medium-grade star stone. Although there are only four star stones in your hand, if you like, I''m willing to exchange 45 ordinary star stones with you."

    "Medium grade star stone! Is there any grade of star stone?"

    Wang Cheng pretended not to know.

    "Of course, there are top-grade stars on the middle grade, top-grade stars on the top grade, and top-grade stars on the top grade. Top-grade stars and top-grade stars can be exchanged for 100 or 1000 ordinary stars, and this number will only be high or low. As for star crystals, it''s even better. A Star crystal is 10000 stars."

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

    "Ha ha, the exchange rate I mentioned is only high or not low. If you want to exchange a piece of top-quality star stone for an ordinary star stone, it''s not difficult to exchange it for twelve or thirteen. As for the star crystal, it''s very good. As for the appearance, it''s easy to distinguish. I won''t say about the Middle-Quality star stone. In addition to the fluorescent overflow, the top-quality star stone is often mixed with a trace of blue, and the top-quality star stone has actually been destroyed It''s called inferior star crystal. It''s crystallized. There''s more purple brilliance in it. The style... It''s somewhat similar to star beast blood crystal. As for star crystal, you don''t need to inquire. In your current identity, you can''t get access to the currency used by big star refiners in bulk transactions. "
