The old man was wearing a gray dress. He always drooped his head. He looked like he didn''t wake up. He was listless. Because he was still lowering his head at this time, Xiao Yao couldn''t see each other clearly. Of course, it didn''t matter what the old man looked like.


    In front of the old man, there is a snake skin bag. On the snake skin bag, there is a strange long knife.


    The reason why it is strange is that the blade of the knife is a black dragon, and the head part just acts as the handle. Every scale on the dragon sword looks so clear. Just looking at the knife, Xiao Yao can feel a great momentum, as if the surrounding air became cold in this moment.


    "Brother Xiao, what''s the matter?" The southern sky on the side asked in a low voice.


    "This knife, it looks strange." Xiao Yao whispered back.


    Nan Tianyuan turned his face and looked at the black broadsword. After a long time, he didn''t see any clue. He could only shake his head: "brother Xiao, I really don''t find anything unusual about this broadsword. It can only be regarded as an ordinary soldier, even without aura."


    "No aura?" Xiao Yao was a little surprised, "but how can I feel that there is a flow of energy in it?"


    Nan Tianyuan knows that Xiao Yao is not the kind of person who likes to joke, so he immediately turns around and looks at the knife, but it''s the same as before. After watching it for a long time, he doesn''t feel what''s different about the knife. Is there something wrong with his perception? After thinking about it carefully, he shook his head again. It''s nothing wrong with his perception. But is there something wrong with everyone''s perception here?


    If this knife is really not simple, why is no one interested in putting it here?


    When nantianyuan was thinking about this, Xiao Yao had already come to him and squatted down to observe the big knife carefully.


    The closer the distance is, the longer you look at it, the clearer the familiar feeling is.


    Nantianyuan looks at Xiao Yao''s appearance at this time. He doesn''t dare to disturb him. He can only stand quietly and keep silent.


    Suddenly, Xiao Yao raised his head, looked at the old man and said, "I want your knife."


    In fact, even now, Xiao Yao didn''t understand the real mystery of the knife, but he believed that it was worth taking away by himself!


    "Well?" The old man suddenly raised his head. The skin on his face was wrinkled and looked like dry bark. His eyes were twinkling with fine awn. Looking at Xiao Yao, his eyes were full of surprise. "Are you interested in this knife?"


    "Yes." Xiao Yao nodded his head.


    "Ha ha!" The old man burst out laughing, "Why are you interested?"


    Xiao Yao frowned and said, "I''m just interested. I think it''s good-looking. Can''t I?"


    The old man squinted at Xiao Yao, his eyes filled with doubt and disbelief: "there are so many people at the trade fair, and countless people pass by in front of me, but only you stop and are interested in this knife. Is it just because it looks good? Besides, it''s not just the knife that looks good here. "


    Xiao Yao was already impatient: "I''m just interested in this knife, that''s all. Why do you talk so much? If you don''t want to change out, why talk so much? Why come to the trade fair? "


    "I didn''t say I didn''t want to change out!"


    "Since you want to change, what are you doing for a long time to show your eloquence?" Xiao Yao said with a frown.


    The old man took a breath.


    Damn, are young people so angry now?


    "Well, since you want it, I''ll take it for you, but it''s not so easy to change my knife." The old man said with a smile.


    This time, there is no need for Xiao Yao to express his opinions. Nan Tianyuan immediately expressed his high dissatisfaction.


    "I said, old man, don''t you want to take this piece of rotten iron and start asking for a lot of money?" Nan Tianyuan said angrily.


    The old man glared at the South sky far, and his eyes were almost staring out: "do you think it''s just scrap metal?"


    "Hey, I''m not the only one who sees it like this. Many people around me see it like this. Otherwise, why didn''t anyone come here to have a look at your broken knife? " Nan Tianyuan said.


    The old man snorted coldly and said, "do I force you to buy it again?"


    "..." Nan Tianyuan suddenly felt that what the old man said was reasonable. He was speechless.


    To be honest, they didn''t force him and Xiao Yao to buy the knife.


    This is a matter of willing to fight and willing to suffer.


    "I''ll trade you ten eight pills. What do you think?" Xiao Yao said.


    "Well?" The old man was stunned. He laughed, waved his hand and said, "I want twenty seven pills."


    "I don''t like grass! Old man, are you crazy? Do you know what you''re talking about now? No, I''m really curious. What''s in your mind? If my elder brother can look up to you with this broken knife, it will give you great face. Do you want twenty seven grade pills? " I''m going crazy in the south.


    The way he looks at each other is like looking at a psycho.


    The old man squinted at the South sky, and finally his eyes fell on Xiao Yao.


    "I''m not better than that. You have to exchange it with me. If you think it''s worthless to you, you can go back now." The old man said seriously.


    The southern sky on the side pulled up La Xiaoyao and said, "brother Xiao, we don''t need to pay attention to him. Let''s go straight. Anyway, there are many good things ahead. Twenty seven grade pills can be replaced by lingbing. Let''s not delay here."


    Xiao Yao turned his face and looked at the South sky far away. He shook his head and did not move his face.


    After taking a deep breath, he took out twenty seven pills from the ring.


    "It''s yours." Xiao Yao said.


    "You really agreed?" The old man looked at Xiao Yao, a little surprised.


    "Yes." Xiao Yao suddenly a little unhappy, "are you going to go back?"


    "Ha ha! That''s not true. In fact, the reason why I said I wanted twenty seven grade pills is just to try it out. " The old man said with a smile.


    "What do you want to test?" Xiao Yao asked.


    "Try to find out if you can really understand the value of the black dragon sword. Now it seems that you really know the goods. Take away the knife. I don''t want anything." Said the old man.


    "Nothing?" Xiao Yao was a little surprised.


    The southern sky on the edge is far away, and it''s a bit encircled.


    He really didn''t know what the old man was going to do.


    How can he not guess and understand what the other party says and does?


    Is this old man really from another planet? "What''s the matter? Isn''t it good for you that I don''t want anything?" Asked the old man.


    Xiao Yao shook his head: "if you really do not want anything, I will feel pressure, which is equal to I owe you a favor."


    "Ha ha! That''s good. You know that? " The old man said, "I just want you to owe me a favor. Can''t I?"


    "What do you want to do?" Xiao Yao is going crazy.


    "If I don''t do anything, I just want you to owe me a favor. Is there anything I can''t do?" Asked the old man.


    Xiao Yao takes the black dragon knife and looks at the old man.


    "Well, I promise you." Xiao Yao said, "I owe you a favor."


    Just when Xiao Yao and Nan Tianyuan are going to leave, they are stopped by the old man.


    "Wait a minute, leave your name. After all, you owe me a favor. If I want to use this favor in the future, how can I find you?" Said the old man.


    Xiao Yao turned his face, looked at the old man and said, "Ding Liuzhi."


    The old man shook his head.


    Xiao Yao suddenly felt tight in his heart.


    The old man walked slowly in front of Xiao Yao. It seemed that if he walked a little faster, he would immediately fall to the ground.


    After waiting for him, the old man said, "what I want is your real name."


    "..." hearing these words, Xiao Yao knew why he had felt nervous before.


    "That''s my real name. What''s the problem?" Xiao Yao said.


    He didn''t know whether the other party really saw the clue or was fooling him in such a way.


    The old man was a little unhappy: "if you have to say that, I''d better give back the black dragon sword. I don''t want to see you so insincere."


    Listen to each other have already said this point, Xiao Yao know that he can''t continue to hide.


    "My name is Xiao Yao."


    "Xiao Yao?" The old man was stunned at first, then showed a sudden look, nodded slightly, "no wonder, I knew... OK, you can go!"


    The old man waved his hand.


    Xiao Yao was silent for a long time, turned around and left with Nan Tianyuan.


    Although he did not know who the old man was, he knew that the old man was definitely not simple.


    Moreover, he also has a feeling that he and the old man will still have a chance to meet in the future.


    "Brother Xiao, this old man can see through our appearance. Do you think he will tell the people at the trade meeting?" Nan Tianyuan worried and said.


    After all, Xiao Yao has no identity to enter the trade conference. If this matter is disclosed, I''m afraid he will die here.


    Xiao Yao laughed and shook his head: "don''t worry, that old man won''t do it."


    "Why?" Nantianyuan grabs his head. I really don''t know where Xiao Yao''s self-confidence comes from.


    "If he does, and I die, isn''t it meaningless that I owe him?" Xiao Yao said with a smile.


    Nan Tianyuan gave a bitter smile.


    "Don''t be so careful. That old man is not a fool. He doesn''t have to hurt me like that." Xiao Yao said, "moreover, I believe he has no malice to me."


    "I hope so." Nantianyuan nodded, but he was still nervous.
