Zeng Shuai used the earth escape technique to search the soil under the Flame Mountain. Although the remaining Samadhi True Fire in the valley of the Flame Mountain had been absorbed by the fire elves, the stability of the soil was still very high. Zeng Shuai must Only by using Gang Qi to protect the body can one escape in the scorching soil. After some searching, Zeng Shuai found a lot. After thousands of years of burning, there was no living thing under this land, and many soils and minerals were burned to ashes. Among the vast ashes, Zeng Shuai I actually found a metal that shimmered like stars. In the gray soil, the finger-sized metals that Zeng Shuai found were colorful, like rainbows, and irregular in shape, but they had a metallic texture. It is very obvious in the soil. This kind of metal has not yet been found on the earth, because this kind of metal can only be produced under the exercise of Samadhi True Fire. Even in other volcanic magma with the same high temperature, this kind of metal will not be found, because the volcanic magma has The temperature is not enough. And why has this metal not been found on the earth? Because currently, it is only found under the Flame Mountain, and the extremely high temperature at the bottom of the Flame Mountain is a forbidden area for scientists. They cannot go deep here at all, so they have not discovered it. . However, it is impossible for these scientists to discover this metal in the future, at least not on earth, because at this time, Zeng Shuai has collected all this colorful and strange metal in his own hands. This strange metal with a liquid color has no scientific name on earth, but Zeng Shuai knows that this metal is called Ten Thousand Refinements Fine Gold, but the Ten Thousand Refinements Fine Gold under the Flame Mountain is not as good as the real Ten Thousand Refinements Fine Gold. , the real Ten Thousand Refinements Fine Gold is made by collecting a large amount of precious ores and specially tempering them with Samadhi True Fire. The refined Ten Thousand Refinements Fine Gold is a single piece. Very beautiful. The irregular and irregular Ten Thousand Refined Gold at the bottom of the Flame Mountain is only the size of a finger, but it is only made by burning a few minerals present in the soil. It has not been forged, so compared with the real Ten Thousand Refined Fine Gold, its quality is inferior. Too far apart. And, this is the ten thousand refined gold at the bottom of the Flame Mountain. At most it is only the size of a finger, and there is a lot of fine gold, even the size of peas, mung beans, and sesame seeds. No matter how small it is, it cannot be seen with the naked eye, so Zeng Shuai does not look for the smallest thing that is invisible to the naked eye. . At this moment. After collecting the Ten Thousand Refined Gold, Zeng Shuai only had a full handful in his hand. They were of different sizes and colorful. The color was slightly darker and there was no real Shining of Ten Thousand Refined Gold. But, even so. Still pretty good. ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Zeng Shuai can refine it into a killer weapon with such a small amount of inferior quality. Flying sword? It's too big and requires a lot of consumables. This ten thousand refined gold is simply not enough! Don't even think about it. A defensive magic weapon? It's not enough. The most refined gold can make a gold cake the size of a palm. Where can I defend myself? Even if it protects the lower three inches of the crotch, it is still insufficient. Flying knife? This is also equivalent to an offensive magic weapon, which can be considered, but Zeng Shuai doesn't like to use flying knives, so this idea is also ignored. Finally flying needle? Yes, it¡¯s a flying needle! The last thing flying needles consume is materials, nothing more. The technique of making flying needles is very troublesome. Although it is easy to make a small needle, it actually makes high-quality flying needles. Very difficult. First of all, it is necessary to ensure that the flying needle is straight, secondly the flying needle is streamlined, and finally the flying needle is sharp. Only with these three factors in place can it be ensured that the flying needle can hit wherever it is pointed, breaking the aura, defense, and power. Everything that is hard to break. Of course, Zeng Shuai only needs three of these attack-type flying needles. For a long time, three flying needles are enough for him to use. No matter how many there are, they are useless, because when controlling flying swords and magic weapons, At the same time, if he releases the flying needles, Zeng Shuai can only control three at most. With three flying needles, it can be recycled indefinitely. It is as hard as ten thousand refined gold, and the wear and tear is almost negligible. Three flying needles, with diameters of one millimeter, two millimeters and three millimeters respectively, are matched in thickness. If they are too thick, they waste material and cause large air resistance. The target is obvious and cannot achieve the effect of being invisible. If they are too thin, the impact force will be a bit weak. Not enough, some defensive magic weapons cannot be broken. Now, he makes one millimeter, two millimeter and three millimeter flying needles, which can be used according to specific situations. The length of the three needles is three inches, so as to ensure the power and controllability of the flying needle. The flying needle with a diameter of three millimeters and a length of three inches is already very thick, almost as thick as a cement nail. Zeng Shuai feels that such a thick flying needle of Ten Thousand Refined Gold, although slightly less concealed, is definitely very destructive. It is so strong that it can probably destroy all mortal defensive magic weapons!  "The three flying needles will definitely not be able to use up the Ten Thousand Refinements Fine Gold in his hands. Zeng Shuai also plans to use the remaining Ten Thousand Refinements Fine Gold to refine a set of medical Ten Thousand Refinements Fine Gold needles, so that acupuncture and other things will be convenient in the future. , at the same time, the Wan Lian Jin needle is used for acupuncture, and the effect is definitely much better than ordinary silver needles and gold needles. Thinking of this, Zeng Shuai notified the fire elf who was still cultivating the excess samadhi fire in his body in the Sumeru Ring. The boy's color has gradually changed from purple to purple, with only a little bit of weird red. It won't take long. It could be refined, but Zeng Shuai couldn't wait any longer, and immediately said to the fire elf: "Xiao Huo, there is still a lot of Samadhi True Fire in your body. If you can't digest it all, just use the forging technique to refine it. It's just right." I have a task for you here. Not only can you consume the excess Samadhi True Fire in your body, but you can also practice your blacksmithing skills, killing two birds with one stone. "Xiaohuo is practicing vigorously at this time, and the power of Samadhi True Fire is strong. It was too big. It absorbed it very well, but it was also very tired. It was almost about to explode. He immediately said: "Okay, master, give it to me quickly. I want to refine the weapon!" "Okay, I will give you the materials to make it for me. Three offensive flying needles, and then make me a set of medical flying needles!" Zeng Shuai said, and explained the key points of forging to the fire elf, who immediately started forging. As soon as the forging started, the fire elf's body was filled with purple sparks. The forging scene was extremely hot. It was obvious that this boy was very annoyed and just wanted to release his firepower. In such a state, it was difficult to forge a flying needle that Zeng Shuai was satisfied with. The fire elf melted the Ten Thousand Refined Gold and made it into the form of a flying needle. He gave it to Zeng Shuai, but Zeng Shuai immediately rejected it. . The fire elf didn¡¯t say much. He just took it back, melted it, and continued to build it. Then he showed it to Zeng Shuai, and was rejected by Zeng Shuai. The fire elf continued to melt it and continue to build it and so on. Zeng Shuai was not in a hurry. As long as the fire elves were forging, he was not so anxious. Taking advantage of the fire elves' forging, Zeng Shuai left the Flame Mountain with his sword and flew towards the Ten Thousand Demons Sect.
