Chapter 132: The Mineral Spirit

  Du Fei opened his eyes, bright and spirited, with a refreshed look on his face. He suddenly sprang up and did a flip to stretch his muscles, landing inside with a happy smile: "Ah, so refreshing." At this time, the sky had already lit up, and the scenery in the valley had transformed into a picturesque scene of birds singing and flowers blooming. Du Fei was also attracted by the scenery in front of him, and sometimes when he felt tired, he would stop to appreciate the beauty of nature, which was not a bad way to relax. Du Fei closed his eyes again, took a few deep breaths of the cool air, slowly opened his eyes, and took out the Wordless Heavenly Book: "Let's go back."

  Only to see the wordless heavenly book suddenly shine with a burst of white light on its surface, a space vortex instantly appeared in front of Du Fei, and Du Fei rushed into the space vortex and disappeared. And just as Du Fei disappeared, the space vortex also disappeared along with him.

  Inside Tianzhu Brook

  Du Fei stood at the edge of the casting platform, gazing at a large pile of silver-white iron ore in front of him. These were all silver steel iron stones, and for half a year, Du Fei's daily task was to take them out and hammer them, not for anything else, but to improve his mastery of the Thousand Forgings Hundred Refinings technique. Now, Du Fei's Thousand Forgings had also reached an extremely proficient level, and those silver steel iron stones were also hammered by Du Fei into a relatively pure state. However, Du Fei did not use those silver steel iron stones to cast any equipment again, but simply refining the silver steel iron stones was enough. If these silver steel iron stones were used to cast weapons now, they would be even more solid than the second batch of silver snow that Du Fei had cast. Originally, Du Fei also wanted to cast more weapons and equipment, but the Wordless Heavenly Book did not agree with him doing so. The reason was extremely simple: quality is better than quantity. Although Du Fei liked to argue with the Wordless Heavenly Book, when it came to cultivation methods, he always followed its arrangements.

  "Is today's task still about hammering these silver steel stones?" Du Fei asked the Wordless Heavenly Book with some disappointment.

  "What, you're unwilling?" the Wordless Heavenly Book wrote.

  "It's already halfway through the year, and you still haven't found anything else to cultivate?" Du Fei asked.

  "It's been half a year since you've been mining this pile of worthless rocks and you haven't even gotten one piece of ore." The Wordless Heavenly Book wrote.

  "Mineral essence?" Du Fei looked at the words on the wordless heavenly book in surprise and asked.

  "Miner, don't you know how to read?" The Wordless Heavenly Book wrote.

  "What is a mine spirit? Do silver, steel and stone have mine spirits?" Du Fei asked in confusion.

  "Nonsense, as long as it's an ore, there will be a mineral spirit. It's just that you haven't hammered it out yet." The Wordless Heavenly Book wrote.

  "Hey, why didn't you mention this before?" Du Fei asked with sudden interest.

  "Before, your kid's punching skills were too poor, and even if I told you, it wouldn't be of much use. What's the point of saying anything? Now, however, your kid's punching skills have improved somewhat compared to before, so I think it's time for me to tell you about this mine." The Wordless Heavenly Book said.

  Du Fei also stopped what he was doing and sat down on the ground with his legs crossed, staring at the changing wordless heavenly book.

  "The essence of ore is the purest part of the ore, and it's called the essence of the ore. Generally, after smelting, ordinary ores can remove impurities, and the fewer impurities in the ore, the better the material is. However, the more you want to remove the impurities from the ore, the harder it becomes. At first, it's relatively easy, but as time goes on, when there are few impurities left, it becomes increasingly difficult to remove them.

  Just like the silver steel iron stone in front of you, this kind of ore is naturally less impure, and its density and hardness are already quite high. However, just because there are fewer impurities doesn't mean there aren't any. If you were to further smelt and refine the silver steel iron stone, its density and hardness would increase again.

  Some casting masters think they're very strong and have a high level of casting skills, but when they see that an ore can no longer be refined or smelted, they think they've already removed all the impurities. However, this is just their personal opinion. In reality, it's because they don't have enough skill to discover the deeper impurities hidden within the ore.

  A true casting master would never think they could completely remove all impurities from an ore, and there's no such thing as a completely pure ore." Du Fei was also surprised by this.

  "Then isn't your master also unable?" Du Fei asked.

  "That's right, I said it before, there is no absolutely pure ore, even the old master can't refine absolutely pure ore." The Wordless Heavenly Book wrote.

  "Oh, then what does all this have to do with that mine spirit?" Du Fei asked.

  "Good question, this is exactly what I wanted to tell you. The old master also wanted to refine the absolute purity of the ore before, and almost went crazy for it, but he couldn't refine the absolutely pure ore. One day, during the refining process, the old master suddenly had an epiphany and understood that there are no absolute things in the world, everything is relative. In fact, all things are interdependent, and nothing can exist alone in this world. To exist in the world, one must coexist with other things. Only when filled with all things can it be called a world. After the master's epiphany, his cultivation and casting skills both soared to a terrifying level.

  The ore is the same, only by combining with other impurities can it become an excellent casting material. The mineral essence is the best match between the main ore material and other impurity materials. Generally speaking, if the impurities account for less than 10% of all the ore, it's called a mineral essence."

  "Oh, I see. So you're saying that as long as the ratio of impurities to minerals is within one to nine, it's considered a mineral essence?" Du Fei exclaimed excitedly.

  "It's more or less this meaning." The Wordless Heavenly Book wrote.

  "How much impurity do you think this sword of mine has?" Du Fei asked, then took out the Silver Snow and swung it back and forth in front of the Wordless Heavenly Book.

  "It's roughly around 60-70%, which is considered a subpar work. It's simply a waste of materials." The Wordless Heavenly Book wrote.

  "This is much harder than the initial casting of the knife, you actually say it's a waste of materials." Du Fei said with some exaggeration as he took a few steps back.

  "Let me tell you, when you first forged the Shi Zhuo knife, the purity of that ore was over 80%. What material is that? It's just high-quality iron ore. This silver steel iron stone is originally more solid than high-quality iron ore. The sword forged from it will definitely be harder than one forged from high-quality iron ore. How dare you say otherwise." Wrote the Scripture of the Wordless Sky.

  "Oh, I see," Du Fei said with a gloomy face, "Well, what level have the ores on my furnace reached?" Du Fei asked anxiously.

  "It's about seventy-five percent." The Wordless Heavenly Book wrote.

  "Hey, right, how can you tell?" Du Fei asked.

  "Look at the luster, look at the weight, look at the density." The wordless heavenly book wrote.

  "How is it?" Du Fei asked.

  "The refined ore is much brighter than the original ore, because after refining, the density inside is also compressed, and the impurities removed are more numerous, so the weight will be heavier." Wu Zitian explained. Du Fei saw this and nodded heavily a few times, saying: "Oh, I see."

  "What, you understand everything?" asked Wu Zi Tian Shu. Du Fei shook his head and said: "Not everything, but almost."

  "Does it make sense? It's useless if you don't have this kind of skill, do you?"

  "I don't know, but I can try," Du Fei said, taking out the Bao Tian hammer and walking towards the casting platform.

  "Wait, hear me out before you do anything." The wordless heavenly book wrote. Du Fei saw that the words on the wordless heavenly book also stopped in their tracks and read: "As long as you can refine a knife with the same materials that can cut through the second silver snow without damaging it, you're more or less successful."

  "Oh, I see. So it means that if you can forge a weapon with silver, steel, iron and stone to cut off the secondary Silver Snow without damaging it, then it's considered a success, right?" Du Fei asked.

  "It's almost done, you can go try it now." Seeing this, Du Fei still wordlessly began to hammer away at the silver steel iron stone on the casting platform.

  This hammering technique is indeed difficult. The ore in front of Du Fei, which has been pounded for nearly half a year, already has a purity of over 70%, but after pounding for half a day, Du Fei didn't see any change in the pile of ore. The more he wanted to refine it to a higher level, the more difficult it became. Du Fei had previously thought that as long as he kept pounding the ore, it would be fine, but after trying, he realized it wasn't that simple.

  He sat on the ground, panting heavily, and picked up the wordless heavenly book beside him, asking: "Were you just messing with me? Why didn't I see any reaction after pounding for half a day? The ore on the casting platform didn't change at all?"

  "What are you talking about? Are you saying I just deceived you?" wrote Wu Zitian.

  "I think it's possible," Du Fei panted.

  "I deceived you, it's because your own strength is not enough, and yet you're still here suspecting me." The Wordless Heavenly Book wrote.

  "Not strong enough?" Du Fei blinked and asked.

  "Yes, if your strength were a bit stronger and the power you wielded was greater, those ores wouldn't be in this state. This can only mean that your current cultivation is only enough to hammer the ores to this extent. I have no way either." The Wordless Heavenly Book wrote.

  "You're not saying I had a chance of defeating the Mineral Warrior before? Why can't I now?" Du Fei asked.

  "I'm just saying there's a chance, I didn't say it's definitely going to work. Ah, never mind, you just focus on cultivating well and when the time comes, you'll definitely be able to do it, I'm not deceiving you." The Wordless Heavenly Book wrote.

  "Huh? You seem to be hiding something, don't you? Spit it out, is there something you're not telling me?" Du Fei suddenly grabbed Wu Zi Tian Shu and asked with a fierce tone.
