At the beginning, ye Zan just built the foundation successfully. Yuqingzong people came to congratulate and gave their gifts. Among them, Liu Qian, the Dan master of yuqingzong, gave Ye Zan a seemingly ordinary bone claw. Liu Qian didn''t know where the bone claw came from. He only knew some interesting abilities.


    However, the bone claw in Ye Zan''s hand has repeatedly played a vital role. First, in the place where the demon God fell, ye Zan broke through the powerful defense with bone claws and defeated Cheng pan, who was the incarnation of the "demon God". Later, when fighting against demons outside the sky in the hell, ye Zan threw the nuclear bomb into the space of the world outside the sky by using the special ability of bone claws.


    Of course, there are gains and losses. After ye Zan used the bone claw in the underworld, he was integrated into his left arm by the bone claw. He didn''t know whether it was a blessing or a curse. Fortunately, with his current strength, he can suppress the bone claw without breaking his arm like the first time.


    Ye Zan has always been curious about the origin of bone claw, but Liu Gan can''t provide any clues at all. Even if the bone claw was integrated into his left arm, he could only be sure that it was not a witch bone, but seemed to be the remains of some unknown creature.


    Ye Zan didn''t expect that this time he had a whim and wanted to exchange Tiangang refining pill for strange things. Unexpectedly, he saw something similar to the bone claw. Or it can be said that the bone claw on the floor and the bone claw integrated into his left arm are most likely the same root and homologous pair.


    With this idea, ye Zan didn''t hide his interest and directly asked the stall owner about the origin of the bone claw.


    Hearing Ye Zan''s inquiry and knowing that a business might be done, the stall owner immediately cheered up, smiled, picked up the bone claw, handed it to him, and said, "Wuji Taoist has a friendly eye. I don''t dare to say what other things are like in this stall, but this one is absolutely in line with the requirements of Taoist friends."


    "Hehe, I''m really interested in this thing, so I want to ask Taoist friends about its origin." Ye Zan said to the other party with a smile, but didn''t reach out to pick up the bone claw handed by the other party.


    Ye Zan is worried that this bone claw, like the previous one, will integrate into his body. Although, with his current strength, it is no problem to suppress a bone claw. However, who knows if there will be any unexpected changes after these things form a pair. If the two bones and claws are not as simple as one plus one, he may face big trouble.


    In addition, after all, this transaction has not been reached. Ye Zan directly integrates things into his body here. Can''t the other party make a price at will! If we don''t agree in the end, will ye Zan just be here and cut off his arm and return it to the other party in front of so many people?


    Seeing ye Zan''s bone claw, the stall owner frowned somewhat puzzled, thinking that the other party despised it as a thing of the dead, so he said: "Wuji Taoist friend, don''t look at this bone claw as a human remains, but in fact it is by no means a human thing."


    "Oh?" Ye Zan was slightly surprised. He didn''t quite understand why the other party said so, but he immediately asked, "do you know the real origin of this thing?"


    Yezan''s best surprise is the origin of the bone claws. If we can find out their origin, we may have a better way to control them. After all, the ability of this bone claw is quite strong. It simply sees space as nothing, and there must be a space Avenue.


    "This..." however, hearing Ye Zan''s question, the stall owner looked very embarrassed, shook his head and said, "I''m afraid I''m going to disappoint Taoist friends. If I knew the origin of this thing, I''m afraid I wouldn''t exchange it with Taoist friends."


    "How can you be sure that this is not a human remains?" Ye Zan asked with some disappointment.


    "The remains of the Terran have no such ability." the stall owner said, took a rusty copper arrow from the ground and put it on the palm of the bone claw in front of Ye Zan and trees. Then, under the gaze of several people, I saw the rusty copper arrow, which turned into a brand-new arrow as if the image was inverted.


    "Eh, what kind of ability is this? It turns the arrow into a new one!" when he sees the change of the copper arrow, the forest wood can''t help but cry in surprise.


    While Lin Shumu was surprised, the copper arrow in the palm of the bone claw changed again, and turned into a piece of copper ore little by little. However, there are many cavities on this copper ore, which is still a relatively pure copper.


    "The ability of the bone claw is a bit like looking back on time, which can make some things go back to the original. Just take the copper arrow for example. After all, a lot of impurities are removed from the copper mine to refined copper and then to the arrow, so that it can not be really reduced to a piece of copper ore." the stall owner explained while taking out the piece of something similar to ore from the bone claw, And handed it to Ye Zan.


    Ye Zan naturally didn''t have any fear about the copper block, so he stretched out his hand to pick it up. He scanned it by scientific and technological means and immediately knew the structure of the copper block. Indeed, as the stall owner said, there were many impurities in ordinary copper ore.


    Ye Zan squeezed the "copper ore" into a copper pill with a slight force on his hand, and then asked, "according to Taoist friends, does this bone claw contain the avenue of time?"


    Although Ye Zan is asking each other, he actually has an answer in his heart. This question is more just to test each other.


    When the stall owner heard this, he smiled bitterly and said helplessly: "To tell you the truth, my sect leader and several elders had guessed like Taoist friends. Unfortunately, no matter what method we use, we can''t really understand the way of time. Therefore, we think this thing may come from an evil devil outside the sky, so it can''t be a human remains."


    Naturally, there is a way of time in the world. For example, many secret places of the cave have the ability to change the speed of time. This ability to change the speed of time is actually an application of the way of time,


    If the way of time contained in this bone claw is the way of time in the world road. Then, the value of this bone claw can''t be exchanged for several Tiangang refining pills. Moreover, others also have the opportunity to use this bone claw as the medium to understand the real way of time.


    Since the stall owner said that he could not understand the so-called way of time from the bone claw. It is very likely that the way of time of the bone claw is not the way of time in the world road. Therefore, it can be further inferred that the bone claw should not be a thing in this world, but most likely from an evil demon outside the sky.


    However, what the stall owner said is nothing new to Ye Zan. He has a bone claw in his hand. Although it belongs to the avenue of space, it also does not belong to the avenue of heaven and earth.


    "Oh, then, do you know more about the origin of this bone claw?" Ye Zan asked curiously.


    However, ye Zan was disappointed by the result. The stall owner shook his head helplessly and said, "Taoist friends, forgive me. If this thing is really an evil thing outside the sky, it should at least be traced back to before the collapse of heaven and earth. Even though our clan has a long inheritance, there are not many records about the events before the collapse of heaven and earth, let alone the things about it."


    Indeed, most of the things left by extraterrestrial demons in the world today are left over from before the collapse of heaven and earth. That is, only Shenhua domain has experienced another invasion of extraterrestrial demons not long ago, which made Ye Zan a war fortress of extraterrestrial demons.


    Therefore, in addition to the Shenhua realm, all other realms that involve demons outside the sky basically date back to before the collapse of heaven and earth. Such a long time is enough to erase many things, especially for practitioners, which may have no practical value. Even if some information has been handed down since before the collapse of heaven and earth, it can not be related to this bone claw, Maybe it''s about other extraterrestrial demons.


    Ye Zan certainly knows this, so although he is disappointed with the other party''s answer, he didn''t expect much.


    The stall owner failed to answer Ye Zan''s question. For a moment, he was confused about ye Zan''s intention, so he had to ask again carefully: "Taoist friend Wuji, do you still have interest in this bone claw?"


    Ye Zan is of course interested. He just hesitates which hand to use to pick it up. If he uses his right hand to pick it up, maybe the bone claw will integrate into his right hand. If he uses his left hand to pick it up, maybe there will be some "chemical reaction" between the bone claw in his left hand and the bone claw.


    After hesitating for a moment, ye Zan finally nodded and said, "let''s make friends laugh. I''m really interested in this bone claw. After all, it contains the power of time. It''s a very rare thing. However, we''d better negotiate the price first."


    "Oh, that''s natural!" the stall owner didn''t know what ye Zan was worried about, but since Ye Zan said he was interested in it, he didn''t bother to think about anything else. Then he asked, "but I don''t know what price Taoist friends are going to pay for this Bone Claw?"


    Ye Zan pondered for a moment, stretched out two fingers and said, "although this thing contains the power of time, it is not the road in this world after all. Since Taoist friends exchanged it, I must agree with it. Therefore, I think the two Tiangang refining pills should be worth it."


    "Two!" the stall owner hesitated. After all, ye Zan had shown his interest in the bone claw. Naturally, it would be better to bargain. So he continued: "Wuji Taoist friend, I''m not greedy. After all, this thing is a legacy of evil spirits outside the sky. Its value is much worse than that of the Longmen stone tablet. So..."


    The Longmen stone tablets, especially those from Hailong palace, are indeed rare. However, I''m afraid the bone claws left by demons outside this day are even rarer than the Longmen stone tablet. Therefore, simply from the perspective of scarcity, the bone claws should not be less valuable than the Longmen stone tablet.


    In addition, the Longmen stone tablet is almost useless to practitioners, but the bone claw contains the power of time and can turn copper arrows into copper blocks. Therefore, in terms of its use value, the value of the bone claw to practitioners is naturally stronger than the Longmen stone tablet.


    Seeing the other party compare the Longmen stone tablet, ye Zan smiled and said: "I can understand what Taoist friends mean. Since Taoist friends compare the Longmen stone tablet, I can also add another Tiangang refining pill. However, the Longmen stone tablet is somehow a thing in this world, and even if practitioners can''t use it, the demon family with real dragon blood can work. And the power of time contained in this bone claw is difficult for us in this world to understand, At best, it''s just an interesting trick like Taoist friends just now. "


    Ye Zan''s meaning is very clear. These three Tiangang refining pills are the highest price. After all, this bone claw is just used to "trick". Of course, his statement is purely to lower the price. Naturally, it is impossible for the other party to know that he can use this bone claw.


    Sure enough, after listening to Ye Zan''s words, the stall owner measured it in his heart, and finally nodded and said, "so, according to what Taoist friends said, three is three."


    If the stall owner knows that ye Zan can really exert the power of this bone claw, I''m afraid it''s not too much to ask for 30 pills. However, if ye Zan doesn''t talk about this, where can others know it. Even at the beginning, in the underworld, so many people saw him throw the nuclear bomb to the world outside the sky, few people knew the reason was the bone claw.


    Therefore, the stall owner is easy to accept. He can exchange this thing that can''t be of much use in anyone''s hands for three top-grade Tiangang refining pills.


    Ye Zan, like the previous transaction, took out three Tiangang refining pills, handed them over and said, "OK, this is my pill. Taoist friends can see the authenticity first."


    The stall insisted that the deal was reached, so he quickly took out a jade bottle, carefully took the pill from ye Zan, identified it one by one, and put it into the jade bottle. After letting go of the three pills, he also picked up the bone claw again, handed it to Ye Zan and said, "Taoist friend, how are you going to collect this bone claw?"


    Ye Zan raised his hand and pointed in the air. A jade ball flew into the air and pulled the light on the bone claw. The stall owner saw this. Although he didn''t understand what ye Zan was worried about, he released his hand and watched the bone claw be included in the jade ball.


    After saying goodbye to the stall owner, ye Zan continued to walk back with the trees, looked at the stalls one by one, and exchanged something he thought was interesting. The 36 Tiangang refining pills in his hand naturally became less and less, and he went to single digits.
