Outside Biyun sect, lingwudao looked at the direction Yang Xuan left and asked, "can you let him go?"


    Xie Tianji beside him smiled: "there''s nothing wrong. His attainments in mathematics are terrible. We''d better make friends with such people."


    Ling Wudao nodded: "what do you think of him?"


    This sentence of the Tao was confused, but Xie Tianji clearly understood it. A trace of appreciation flashed in his eyes and said: "maybe it can really be. Maybe this secret that has been silent for hundreds of years can really reproduce the day in his hands."


    So Wudao didn''t speak again, but his eyes showed a little look of expectation.


    Yang Xuan galloped all the way and soon arrived at Qingxue city. Of course, he had recovered his appearance at this time.


    "Uncle, what have you been doing? Do you know that people will starve to death?" bandit Shuai burst into tears as soon as he saw him.


    Yang Xuan looked at him strangely and didn''t understand what he meant.


    "Where''s the money, where''s the money, where''s the money for dinner?" cried the robber Shuai tearfully.


    Yang Xuan patted his forehead. When he left, he forgot to give the stolen handsome money. Originally, it was nothing. Can a venerable master starve to death alive? But don''t forget that the cultivation of bandit Shuai was completely sealed by him.


    "Mistakes!" Yang Xuan apologized, but also a little strange: "how did you stick to it these days?"


    "I''m in debt. Speaking of this, you hurried to the counter to settle the account and urged him several times." the robber Shuai was speechless. If he couldn''t beat Yang Xuan, he wanted to beat Yang Xuan.


    When Yang Xuan came to the counter and wanted to check out, he was told that all the accounts had been settled.


    "Who did it?" Yang Xuan was a little strange, but the shopkeeper didn''t speak. He just made an invitation gesture to Yang Xuan.


    As the shopkeeper came to a private room with elegant environment, Yang Xuan knew who was inside before he entered.


    The shopkeeper let Yang Xuan into the elegant room. After closing the door and leaving, Yang Xuan smiled and said, "you are well-informed."


    Qingshuang smiled like a bud in bud: "it''s not that Qingshuang is well-informed, but that I''ve been waiting for young master Yang here."


    Yang Xuan was not polite either. Seeing that there were fruits on the table, he grabbed an apple and ate it.


    "What''s the matter? Let''s talk first. If I''m a son-in-law, I won''t talk about it."


    Qingshuang listened interestingly and joked: "Mr. Ren studies heaven and man. Even the great master without Tao plays with his hands. He''s afraid to be a small son-in-law?"


    Yang Xuan squinted his eyes. At this moment, he immediately understood that in the Piyun sect, there must be the eye liner of the green snow country, and the eyeliner would probably be in the huge Laboratory of Xie Tianji.


    It is very likely that there is also the Royal eye line of the Royal snow Royal in the great spirit, and it is not clear that the dark line of the king of heaven and the Piyun sect is also uncertain.


    But it''s none of his business. The intrigue between the three forces has nothing to do with him. He''s just a passer-by, digging some useless stones by the way.


    Thinking of this, Yang Xuan smiled and said directly, "what''s the matter, say it."


    Qingshuang pursed her lips without any nonsense: "Huitian pill."


    Yang Xuan bit an apple and said strangely, "haven''t you already given you twelve?"


    Qingshuang shook her head: "it''s not enough. If possible, on behalf of Qingxue royal family, I invite young master Yang to become a Royal Sacrifice in China."


    Yang Xuan was slightly stunned. Was it enshrined by the royal family? Qingxue country has a big appetite.


    He glanced at Qingshuang, but did not directly refuse, nor did he deny that Huitian pill was made by him.


    There is really nothing to deny and there is no need at all.


    "If you can get something in exchange and exchange it for some huitiandan, it should not be a problem."


    Qingshuang''s face didn''t show a disappointed expression.


    "Young master Yang wants to exchange something?" Qingshuang asked.


    Yang Xuan thought about it, but he was a little worried. He really didn''t have anything badly needed at this time. If he changed more herbs, he wouldn''t need it.


    Qingshuang is not in a hurry, just waiting quietly.


    Yang Xuan thought and thought, and simply asked, "how much do you need?"


    "The more the better, at least fifty." the green frost lion opened his mouth.


    Yang Xuan smiled. He looked at Qingshuang like a fool and said, "do you know what you''re talking about?"


    Qingshuang also smiled and looked at Yang Xuan like a fool: "we have tested the efficacy of Huitian pill. It is indeed against the sky, and we also know that fifty Huitian pills are invaluable."


    "Just know. Then, what are you going to exchange for fifty elixirs?"


    Qingshuang looked at Yang Xuan, his eyes showed a trace of strangeness, and then said, "young master Yang doesn''t lack anything. What we can take out is nothing more than some medicinal materials."


    Yang Xuan stood up, took out an apple from the plate and said, "this apple is good. Let''s go!"


    With that, he walked directly to the door while biting the apple.


    Qingshuang didn''t move, and there was still a smiling expression on her face, like a bud in bud. Just when Yang Xuan was about to go out, she gently opened her mouth, like a thunder: "what if you add the key to the forbidden area of Juling sect?"


    The apple in Yang Xuan''s hand fell to the ground and rolled twice, covered with dust.


    He turned slowly, his face very gloomy, his eyes like a knife.


    Qingshuang didn''t flinch at all. She still smiled and looked at Yang Xuan quietly.


    After a long time, Yang Xuancai said word by word: "how do you know?"


    Qingshuang didn''t answer his question, but asked again, "what do you think of young master Yang?"


    Yang Xuan was silent. He had to say that Qingshuang''s proposal directly detained his life door.


    "Good!" Yang Xuan pondered for a moment and nodded directly.


    Qingshuang smiled, like a flower blooming: "a hundred elixirs!"


    Yang Xuan felt that his anger was almost uncontrollable, and his face was more gloomy. If possible, he wanted to slap the woman in front of him.


    Qingshuang seemed to understand what he thought and explained with a slight sigh: "I think young master also knows that there are only a few people who can get access to the forbidden area key in Juling sect. If we send the forbidden area key to young master Yang, what does it mean, young master Yang don''t know?"


    Yang Xuan took a deep breath and pressed down the anger.


    If Qingshuang can really send the forbidden area key to him, how can he not know what it represents.


    That means that a dark line that has been lurking for hundreds of years in the green snow country in the Juling sect is going to be abandoned.


    Such a price is not small.


    After understanding this, he also had doubts in his heart. Is it worth trading such a dark line of 100 years'' operation for 100 elixirs?


    Qingshuang seemed to see Yang Xuan''s doubts and whispered: "exchanging huitiandan with Childe Yang is only the second and most important purpose. She still wants to invite childe yang to become the sacrifice of Qingxue country. Where is Zhang Heng, but there are still some mathematical problems. She wants to ask childe Yang."


    Like a thunderbolt, Yang Xuanli understood.


    Or mathematical knowledge. The main purpose of qingxueguo''s making such a great sacrifice is still the mathematical knowledge mastered by Yang Xuan.


    "How to deal?" Yang Xuan went straight in.


    "Alchemy first!" Qingshuang had no nonsense.


    "Good!"
