Although the barbarians are somewhat hostile to humans, human monks generally no longer appear in front of ordinary barbarians. In addition, barbarians' body cultivation and monks' internal cultivation have many resources that are not in common demand. Therefore, there are actually many places where the three cultivators gather in the barbarian territory, and Lingye Valley is one of them. Lingye Valley is in the mountains. The valley shaped like a leaf is guarded by a large formation. The Valley Master is a strong man in the late stage of out-of-body experience. It is said that he is about to take the step of distraction. He is the strongest person within a thousand miles, and the owner of Lingye Valley is willing to do charity, so there are many casual cultivators gathered here, including some barbarian body cultivators. Jiang Lin only knew the location of Lingye Valley after he accidentally met a monk half a month ago. Jiang Lin exchanged the materials on his body for some spirit stones and rented a cave in Lingye Valley. The casual cultivators in Lingye Valley all live in caves. The higher you go, the richer the spiritual energy, and the more spiritual stones you need to rent. Jiang Lin just came here to trade, and never thought about breaking through the knot, so he just rented an ordinary cave. He also bought a decent alchemy furnace and refined a furnace of elixirs. Compared with elixirs, elixirs are naturally more expensive, so Jiang Lin, who has an alchemy furnace, plans to sell the elixirs to obtain some spiritual stones. "How do you sell this bottle of high-grade Peiyuan Pill?" A monk with a sword on his back walked up to Jiang Lin's stall and asked. People living in Lingye Valley can set up stalls in Lingye Valley. The elixirs refined by Jiang Lin are all for use by Jindan stage monks and a few Nascent Soul stage monks. This is very consistent with Jiang Lin's late-stage Jindan cultivation. Monks at the golden elixir stage of the top-grade Peiyuan Dan can still use it. "No counter-offer for 100 spirit stones." Jiang Lin glanced at the monk who asked the price. He was in the early stage of the golden elixir. Then he spoke calmly. The so-called one hundred spiritual stones are actually one hundred low-grade spiritual stones. The spiritual stones are also divided into four levels: low-grade, medium-grade, high-grade, and top-grade. The more advanced spiritual stones contain more spiritual energy, are purer and easier to absorb and practice, and the higher their value. The exchange ratio is somewhat unstable. After all, high-level spiritual stones can do things that low-level spiritual stones cannot. If you are in urgent need, you can exchange at a lower ratio. If you are not in urgent need, one to one hundred is generally fair. But this only applies to the exchange between low-grade, medium-grade, and high-grade spiritual stones. The ratio between mid-grade and high-grade spiritual stones may be a little higher than this. As for the top-grade spiritual stones, they have a price but no market. It is said that monks in the Mahayana stage can become flying immortals only by practicing with the top-grade spiritual stones. Therefore, the top-grade spiritual stones rarely appear on the market. "100 spirit stones? It's too expensive. I want three bottles. How about 90 spirit stones for each bottle?" Although Jiang Lin said he would not bargain, buying things for both mortals and monks, unless they are in urgent need of very rich people, and There is no one without a counteroffer. After all, it is not easy for casual cultivators to obtain spirit stones. Every stone must be spent on ideas. "There is no bargaining for 100 spirit stones, but if you have any ores or elixirs on you, you can exchange them for elixirs." Jiang Lin refused to let go of the price, but offered a compromise. This is also Jiang Lin's usual compromise method when selling elixirs these days, exchanging the elixirs for ores or elixirs, so that Jiang Lin can continue to refine elixirs and make money in a continuous cycle. "How much spirit stone do you offer per kilogram for copper essence and iron essence?" The monk who wanted to buy the elixir hesitated and asked. "Look at the quality. If it's good, 10 pieces of spiritual stone or two will be fine. If it's not good, it's possible that one piece of spiritual stone weighs 100 kilograms." Jiang Lin nodded and said. Copper essence and iron essence green are the essence extracted from ordinary bronze and mortal iron. They are the most basic materials used to refine mortal weapons and magical weapons. It would be a bit unqualified for refining treasures, but these two materials are one of the most commonly used materials by monks. After all, some rare ores are not so easy to find, but even mortals can smelt iron and copper ores. As long as the monks spend a very small price, they can obtain a large amount of iron and copper that are first smelted from the ore from mortal hands, and then refine it themselves to turn it into iron essence and copper essence used by the monks to refine their weapons. Therefore, it is very easy to obtain iron essence and copper essence, and their value is not high among the rare treasures used by monks. However, if a monk is willing to work hard to refine it, refining a thousand kilograms of copper and iron to less than a penny in weight is still very valuable. However, this kind of refining consumes a lot of time and spiritual energy. If you don't use it yourself, it will be very valuable. Some monks will spend great efforts to refine it. "What price do you give for these two pieces?" The monk took out two egg-sized pieces of copper essence and iron essence from his storage bag and threw them to Jiang Lin. Jiang Lin reached out to catch the copper essence and iron essence, although these two small things were not big. But the weight is not light. This egg-sized piece of copper essence weighs at least five hundred kilograms, while the iron essence is lighter, only about three hundred kilograms. "The refining is pretty good, but it's not the best, so 1 piece of copper spirit stone is 10 kilograms, and 1 piece of iron spirit stone is 20 kilograms. What do you think of the price?" He weighed the two items in his hands.After measuring it, Jiang Lin asked. "It's fair, so 50 spirit stones for copper essence and 15 spirit stones for iron essence, a total of 65 spirit stones. I'll give you two copper essences and two iron essences. Why don't you give me two bottles of high-grade Peiyuan Dan? Like?" the monk said after a moment. Three pieces of copper essence and three pieces of iron essence, the total value is only 195 spiritual stones, which is 5 spiritual stones less than the price set by Jiang Lin for two bottles of high-grade Peiyuan Dan. "Deal." Jiang Lin nodded and did not argue about such trivial matters. Then the monk took out another piece of copper essence and iron essence and handed it to Jiang Lin. Jiang Lin checked the result and nodded, then handed over two bottles of high-grade Peiyuan Dan. The monk also checked it and after confirming that there were no errors, the transaction between the two was completed. Actually, it sounds like the deal of a thousand pounds of copper essence and iron essence is quite big. However, refining copper and iron essences is a job that only monks from various sects or poor casual cultivators would dare to do. For example, it only takes a day or two for Jiang Lin to refine two bottles of Peiyuan Pill. The total amount of elixirs and other things spent was less than fifty spirit stones. In other words, Li Feng could earn double the profit by selling four bottles of Peiyuan Pill, but this monk wanted to refine such iron essence and copper essence. It will take at least half a year to buy mortal iron and copper extracted from ores from mortals, and it will cost at least 80 spiritual stones. Therefore, casual cultivators are generally very poor and do hard work that is not very profitable. Rogue cultivators usually become casual cultivators only when they obtain some complete or incomplete magical arts from a certain cave, or they are from a declining sect. Therefore, they do not have the background of a major sect, and just practicing has consumed most of their energy. They don't have the time or conditions to learn things like weapon refining, alchemy, formations, etc. Therefore, elixirs and magic weapons are very popular among casual cultivators. If they are finished arrays or something, their value is even higher. Therefore, alchemists, weapon refiners, and formation masters are considered a relatively wealthy group of people among casual cultivators, and some casual cultivators will also trade with some sects. "How to sell the Spirit-enlightening Pill?" Not long after the previous monk left, another monk stood in front of Jiang Lin's stall. This is an old man with gray hair and a withered face, who is in the early stage of the Golden Elixir. Although his eyes are still bright and clear, he has reached his twilight years and his body is full of decay. "A piece of 500 spirit stones." Compared with the Peiyuan Pill, which has 100 pieces in one bottle and 200 pieces in two bottles, the Qiling Pill is undoubtedly more formal, and one piece is worth 500 spirit stones. "500 spirit stones, isn't it a little too expensive? This is just a middle-grade spiritual pill." The old man hesitated and said with a timid look on his face. Whether it was Jiang Lin's identity as an alchemist who could refine the middle-grade Ling Ling Dan or Jiang Lin's cultivation level, they firmly suppressed the old man. Therefore, the old man did not dare to show any disrespect to Jiang Lin. In the world of cultivation, it does not mean that you are older and you will be respected because of your seniority. Instead, rely on strength to speak. With higher strength, you can get better resources and be superior. If you are poor in strength, even if you live for thousands of years, you will still have to bow to a child who is stronger than you. "This price can't be less." Jiang Lin shook his head and said, after this month's experience of setting up a stall. Jiang Lin learned a lot. For example, in the world of cultivation, the emotions facing strangers are worse than those of ordinary people. When two strangers meet in the world of cultivation, the most they do is nod, then turn away, and they won't talk to each other unless necessary. They will even ask whether the other party will kill people and seize treasures. So people in the world of cultivation are very indifferent. Although Jiang Lin is not indifferent yet, he will not give in and sell the Qiling Pill at a reduced price just because the other party seems a little pitiful. "Do you think this is okay? I'll bring out 300 spiritual stones, plus this flying sword, a medium-grade magic weapon, in exchange for your spiritual enlightenment pill." The old man hesitated, then gritted his teeth and took out a magic weapon from his storage bag. The shining flying sword said. "Grandpa, this flying sword is your only magic weapon. What do you use it for after you sell it?" Before Jiang Lin could speak, a plainly dressed but youthful and cute little girl ran over from a distance. Just now, the little girl was looking at the cute monster cubs sold by the stall owner at a nearby stall, and did not come with the old man. At this time, he saw the old man taking out the flying sword, so he hurried over. The little girl is eleven or twelve years old, and has already reached the foundation-building stage. Among casual cultivators who don't have many cultivation resources, such a young age and such a cultivation level are already considered good. "If you don't have the flying sword, you can buy it again, but the middle-grade Spirit-Qing Pill is not always available. You have already taken a low-grade Spirit-Qing Pill, and then take a middle-grade Spirit-Qing Pill. Then your understanding is okay Grow a little longer, and you will have hope of forming a pill or even a baby. When you become stronger in the future, just buy a better flying sword and give it to grandpa." The old man touched the little girl's head kindly and said. This is how casual cultivators are passed down from generation to generation. Maybe one day they meet a genius, and the elders will work hard to train him, and a cultivator family will emerge. Maybe one?Not as good as one generation, and finally disappeared in the long river of history.
