Lang Tianya walked to a cubicle, looked at the goods placed on a long case, picked up a short sword and looked at it. The vendor was sitting on a bench behind the desk drinking tea, and he didn't make a noise when he watched the dagger a little distracted.

Lang Tianya had previously handled a lot of internal force alloy weapons, but at that time he did not have internal force, and these weapons were of no use to him at all, so he had never paid attention to them, and he had never understood the internal principles of these weapons. Now that he has the idea of processing the sword embryo, he inevitably has to learn it first.

He held the hilt of his sword and extended the internal force into it. He found that the trajectory of the internal force in this sword is not very clear, and there are many small blank areas, and the internal force particles always give people a sense of intermittent operation in it. This shows that the material of this sword is not very pure, and it should be that the internal force alloy inside the sword contains a lot of impurities.

Suddenly, he noticed that several of the input internal force particles did not seem to be hidden, but were bounced off, so he entered the internal force again and carefully understood the subtleties. Sure enough, a total of five internal force particles were bounced back, and the feeling was exactly the same as that of the pistol, indicating that the sword contained the kind of crystals that could block the aura.

The alloy of internal forces is the only medium that has been discovered so far that allows internal forces to extend out of the body. Lang Tianya once discussed this issue with Xiaobu. At that time, the two discussed the formation of the Reiki needle. Xiao Bu said that with his ability to enter the realm of darkness, he could not let the internal force in his body be released. Therefore, it stands to reason that Lang Tianya cannot do this. But in fact, when Lang Tianya condenses the aura needle, he can attach a small amount of his own internal force particles under the framework of the program and release them to the outside world, and then the program of the aura needle absorbs more aura from the outside world to complete the condensation. This small amount of internal force particles not only strengthened the structure of the Reiki Needle, but also enhanced his perception, making it easier to manipulate. At that time, Xiao Bu said that only cultivators who had reached the sixth level or above could have the ability to use this method to release their internal forces. And like Lao Lang, who has this ability when he just entered the seclusion, he has never heard of it. This is also one of the reasons why Xiaobu thinks Lang Tianya is special.

However, the pistol that fired the aura bullet easily allowed the martial artists below the subtle realm to release their internal force. And instead of releasing a little outside, it fires an aura bullet that can hurt people. Lang Tianya guessed that Xiaobu might not have this kind of weapon in their world. He has explored the inner workings of the pistol, and has tried to replicate the pistol's program with the internal slot, hoping to shoot an aura bullet with his fingers. But his repeated experiments were unsuccessful. This shows that firing Aura Bombs is not something that can be achieved by program alone. He believes that the crystals are the key, and that the small liquid crystals are what make it possible for the internal forces to be released.

He felt that the principle in the pistol was slightly different from the magic spell programming, more like a unique way of using internal forces, but he didn't think that the study of internal forces on Earth had surpassed those of the aliens. That kind of liquid crystal is probably something that aliens don't have. Therefore, those aliens did not develop this way of using internal forces.

Lang Tianya put down the short sword, picked up a few other weapons and tried them, but found no more crystals in them. So he picked up the dagger again and looked at it.

The merchant saw that he put down the sword and picked it up, thinking that he had the possibility of buying it, so he said: "It is a Xuantie sword, I can sell it to you cheaper, you go back to someone to refine it again, and remove the impurities in it, you can improve the quality a lot." ”

Lang Tianya listened to the trader's words, and suddenly understood a little bit why there were no such crystals in the internal force alloy, including the sword embryo in his hand, because they were too pure, and the crystals had been removed as impurities during the refining process of the alloy.

"How much?" He asked the vendor.

The vendor looked at his clothes, and then said, "500,000, a fixed price!" ”

Lang Tianya smiled, and said in his heart: "The alloy content of this Xuantie Sword is only about half, and it would be good if it could be worth 200,000, do I look like a big man?" He lowered his dagger and walked to the next compartment.

This one sells martial arts practice clothes, he just glanced at it a few times, and walked to the next one without stopping. He began to focus on the newer weapons, carefully understanding the textures and the role they played, and imagining how to unblock them to achieve such an effect. In the meantime, he saw two more Darkiron weapons in several other shops that sold weapons, but none of them contained such crystals. When he asked, he realized that these two pieces were relatively new, not as old as the one just now.

Lang Tianya stopped wandering, looked up at the sign, found the location of the toilet, and then he went straight to the toilet.

Lang Tianya didn't really want to go to the toilet, he wanted to borrow the toilet to upgrade the value of the sword embryo first. As soon as he entered the toilet, he found that there was no one inside, and he was quite satisfied, so he picked the innermost compartment to go into. He locked the door of the cubicle, pulled out the sword embryo, and fed the internal force into it. In a matter of moments, the sword embryo was heated to an extremely high temperature, turning from a swarthy appearance to red, then glowing with a pale yellow light, and finally to a blinding bright white.

In the course of his wanderings just now, he found that the more recently manufactured internal force weapons, the purer the material, and the more exquisite the internal structure. If the dark domain of the human body and the rune bone are used to form the program, and the pistol is used to build the function by using the reflective ability of the crystal, then the internal force alloy weapon is using a small amount of impurities to produce different properties.

Like the influence of carbon on steel, internal impurities also have an impact on the performance of weapons, but this is not all the role played by impurities, impurities also have a performance, that is, to isolate the fluency of internal force input, the different distribution of impurities, can make the internal force in the process of operation to produce a little similar to the effect of the force, so as to change its internal local structure, produce the weapon tougher, harder, sharper and other effects, and even recently there have been more functions such as making the weapon glow, heat, deform, etc.

In the past few decades, internal force weapon manufacturing has been one of the most studied knowledge, and has developed into a professional discipline, and has even been divided into many schools. Lang Zaiya didn't want this sword embryo to be too special. He first sorted out the internal impurities, and on the basis of improving the fluency, he only chose two more popular functions, one is smooth and the other is sharp. When in use, as long as the internal force is input, this short sword will make the resistance smaller and sharper with the increase of internal force. Now, as long as it is heated a little more and forged into a sharp blade, it is a qualified finished short sword.

Lang Tianya sent out a little cooling charm to cool down the sword embryo, and then wrapped it in newspaper again before walking out of the toilet. The whole process took him less than ten minutes. As soon as he walked out of the toilet, he heard his mobile phone ringing, and he was about to take out his mobile phone, but found that Qu Weiwen was waving to him with his mobile phone in the distance.

He ran a few steps over, Qu Weiwen dragged him to the auction hall, and urged in his mouth: "Quick, fast, Mr. Tian doesn't have much time, let's hurry up." ”

The inside of the auction hall was not as large as Lang Tianya expected, and it could only accommodate about 100 people. The interior is arranged like a movie theater theater, with chairs arranged in a stepped radioactive manner, and the auction table is below, and the bidders sit down with a downward view. Qu Weiwen said that this can improve their sense of dignity.

Enter through the side door of the auction house, behind which are several offices. Qu Weiwen led him into the outermost room. As soon as I entered, I saw a middle-aged man with glasses and a gentle and elegant man sitting behind a desk, reading a picture book of the lot. He heard footsteps and looked up to see the two of them entering the office, with a professional smile on his face, got up and walked around the desk, and stepped forward to stretch out his hand to Lang Tianya. Lang Tianya also reached out to shake his hand.

At this time, Mr. Tian of the auction house. This is Mr. Lang. Qu Weiwen introduced the two sides.

The three of them whispered a few words, and Mr. Tian got to the point: "Did you bring something?" I'll take a look first. ”

Lang Tianya hurriedly took out the sword embryo sandwiched under his armpit, peeled off the newspaper on it, and handed it to Mr. Tian. Mr. Tian took it and carefully inspected it by inputting the internal force. Lang Tianya had nothing to do, so he observed his surroundings.
