When he was in the Demon Castle, Ivan also heard about the several major alloys in the hands of the Human Alliance, such as the Dragon King Alloy in the hands of the dwarfs, the ax steel and hammer copper in the hands of the dwarves, and the Sariel alloy and the Sariel alloy in the hands of the humans. Gabriel's Alloy, but I have never heard of any famous alloy named Avila on the human side. Naturally, there is no such alloy within the demonic forces. Although Ivan never expected that Viscount George would have any top alloy formula in his hands, otherwise before Ivan could take action, Viscount George's army would have been pushed back by the masters of the Demon Castle organization. Now he only hopes that as Mei The most important thing to Decheng Nesaro is that the properties of Avila alloy should not be too bad. Back in Med City, Ivan changed out of his robe and found a small blacksmith shop without soldiers guarding him. He pretended to look at the finished weapons hanging on the wall of the blacksmith shop. Then he randomly found a topic and started talking to The blacksmith inside started chatting. He carefully controlled the content of the conversation and gradually turned the conversation to the properties of the alloys produced in Med City. In fact, Ivan was also in enemy territory and was a little too cautious. He directly asked the old blacksmith about the performance of the alloy produced in Meide City. It was no big deal because it was not a military secret that needed to be kept secret. In the big market outside Meide City, hundreds of kilograms of alloys are sold every day. Merchants who buy alloys naturally need to understand the performance of these goods. What's more, the things Ivan asked are not involved. to the most sensitive aspects of alloy manufacturing. With a sip of wine in his mouth, the old blacksmith in the blacksmith shop was beating the red-hot metal rough embryo while chatting with Alvin about the properties of various alloys produced in this city as if he were having a casual conversation. The old blacksmith didn't seem to have much respect for Med City, a city where he had worked for most of his life. In his introduction, of the four alloys Med City boasted about, in fact, three of them could barely make enough alloys. Compared with ordinary metals, there are no obvious advantages in terms of qualifications. The only thing that is interesting is the Avila alloy, a second-rate material that is not as good as the top but more than the bottom. Although it is a second-rate product, it has finally got rid of the embarrassing status of being neither better nor worse. Compared with those simple metals, Avila alloy, it is much better in various performance indicators. The most outstanding one is its elasticity and The yield strength has even reached the level of top alloys, so its biggest destination is to be made into machine springs used on various crossbows. However, the reason why Avila alloy is called a second-rate alloy among alloys, rather than a first-rate or even top-tier alloy, is because the machine springs made from it are not inferior to those top-tier alloy products in terms of performance. However, its toughness and plasticity are greatly insufficient. Once it is subjected to a violent impact, it is easy to break. Even if it is carefully maintained, the probability of parts being scrapped will still greatly increase after a hundred times of use. ?The machine spring made of top-grade alloy can be used stably for at least a thousand times. This is the difference between the two. Mechanical springs made of Avila alloy are not standard accessories for military crossbows. At most, they are only used as cheap replacement parts. However, among adventurers, they have a huge market, because shooting in large quantities is a luxury that only the military has. What can only be achieved through training, in the hands of adventurers, a hundred shots are enough for them to end more than a dozen battles. If they survive more than a dozen battles without dying, such adventurers will either retire after making enough money, or they will have enough money. With his military exploits, he suddenly became a noble. By that time, the life of the machine spring is basically not something they should be concerned about. But no matter what shortcomings Avila alloy has, at least the parts it makes can be comparable to top alloys in a short period of time. Even now, Demon Castle has not researched any valuable alloys! There are many alloy formulas of the same grade as Avila alloy. They are scattered in the hands of various human lords on Gray Plains. Most of the alloy formulas have not been mastered by Demon God Castle. With the strength of the Demon God's Castle, it is not difficult to obtain these formulas, but based on a certain mentality of grabbing the best if you want to grab it, these cannot be brought down and do not seem to be able to bring about a completely different outcome for one's own army. The changing alloy formulas have never entered the sight of the controllers of Demon Castle. Although the task hall has also issued tasks to obtain alloy formulas of various grades, in fact, their eyes have always been only on the highest-grade alloys. On the recipe. "In that case, Avila alloy still has some value!" Walking out of the blacksmith shop, Alvin thought to himself. If Avila Alloy can only make replacement parts for other weapons, then Alvin will have no interest in it at all. However, what it can make is replacement parts for crossbows, and the use effect has been verified by Alvin personally. Not inferior to those top alloy products, even if it can onlyShooting more than a hundred times was enough to impress Alvin. In Aiwen's future plan, a large area of ??land around the Lion Heart Valley will be incorporated into his territory in a very short period of time. The key factor in achieving this goal is his unique crossbow attack on the Human Alliance. improvements made. There is a shortcoming in this plan, that is, Ivan cannot make crossbows by himself. He can only increase the number of crossbows by capturing them in battle. If now Ivan can get the Avila alloy formula that can make key parts of crossbows, Once you get it, it will undoubtedly be even more powerful, and it can basically solve the last shortcoming of crossbow manufacturing. "Fortunately, Avila alloy is only a second-rate alloy in the eyes of the old blacksmith. It must not be too difficult to obtain it Viscount George will probably be more vigilant after what happened with Sharo. ¡ª¡ªAm I really going to go into the mine?" Ivan thought with some distress. "Speaking of which, I need Avila Alloy because it can be used to make replacement parts for crossbows. What is Sharo's motivation for wanting to obtain the formula for Avila Alloy?" Suddenly, Alvin thought of Sharo's formula. Talent, intuition. When Aiwen returned to the small building, Joanna was already waiting in the building. She was holding a cup of hot tea and sipping it slowly. Beside her, there were large and small packages of wrapped gift boxes piled up. "You're finally back!" Joanna put down the steaming tea cup in her hand and looked at Alvin's coat. She couldn't see any trace of having touched anyone, and then she nodded with satisfaction, "There's no trouble, okay, okay!" " In your eyes, am I just a stupid young man who is used to causing trouble?" After hearing this, Aiwen walked to her side and sat down with a little dissatisfaction, complained, and then looked down at his feet. Stacked gift boxes. "What are the things in here?" Ivan gently kicked one of the boxes with his toes and asked curiously. "Clothes, weapons, accessories, books, and some novel gadgets." Joanna replied simply. "I don't know what kind of gifts a human viscount would like, but they must be used to those expensive things, so I decided to work hard on the novelty and ancient aspects of the gifts." "The key is, It won¡¯t cost too much to prepare these gifts Well, you are really discerning, and I really think your idea is really good." After being glared at by Joanna, Ivan quickly changed his words. "Since you can speak, get ready. Let's go visit Viscount George." Joanna stood up, took off a dress from the hanger on the side, and threw it on Alvin. "Are you going now?" Ivan reached out to catch the thrown dress and asked with a somewhat shocked expression. "Of course, otherwise after Viscount George gets married, God knows where to find him." Joanna said impatiently. She originally thought that even if this contact trip would not go too smoothly, she would at least be able to talk to a few people. The human aristocrat who had spoken to her was on the line to prepare for a comeback in the future, but the obstacles she encountered in the past few days were obviously beyond her expectation. "Hypocritical and arrogant human beings!" Joanna thought with some depression that nearly half of the month had passed. If she couldn't get any promise from Viscount George, then Joanna's trip would almost be considered a failure. Seeing Joanna¡¯s gloomy expression, Alvin thought for a moment and decided not to mention the Avila alloy to her until the result of her meeting with Viscount George came out. When Joanna and Alvin went to see Viscount George with gifts, after the briefing, the person who came out to greet them was not Viscount George himself, but his eldest son, a second-level warrior in his twenties. Under normal circumstances, Sir Anders will be the future heir to the territory. Viscount George did not come forward. The explanation given by Sir Anders was that his father was worried about the wedding, so he did not want to see strangers during this period. For this reason, Johanna could only accept it with a smile, but Johanna would not accept failure so easily. She quickly cheered up and tried to sell her business to Sir Anders. It's a pity that Sir Anders was willing to come forward to receive the two of them, not because of Viscount George's order, nor because he paid much attention to Johanna's visit. The reason why he showed up was entirely because he heard that Alvin was also following Johanna this time. The reason for the visit is because Aiwen's identity in front of others is that of a young and promising second-level mage. Therefore, although Sir Anders was somewhat interested in the business mentioned by Johanna, he was not very interested. Instead, his attention was always focused on Alvin, and he was warm and welcoming to him. If Sir Anders hadn't shown such a hint of solicitation at the end, Alvin would have thought he had met a gay man. ??????????????????????????????????????????????????????????????????????????The trip to the Viscount Mansion, which had great expectations, turned out to be a complete failure. t! .
