Rise of Rurik

　　The sword embryo has been completed, and the rest is the sharpening stone.

　　 The Cravasons followed the techniques of their ancestors, using a square whetstone finely chiseled from a large piece of sandstone, holding the sword and using it to grind.

　　 It was another cold morning, and Clavasson placed the whetstone on the platform and the short sword on it.

　　 Now that Rurik is still staying at the blacksmith's house, Clavasson really feels a bit wrong.

　　 "Liurik, you can go back now."

　　 "Why?"

　　 "The next thing is to sharpen the sword, and there is nothing to trouble you anymore."

　　 "No, I will continue to watch you work. I want to see how you sharpen your sword."

　　 "Oh, well, maybe you will be bored." Clavasson shook his head slightly, because sharpening the sword is indeed a boring process.

　　Are there any really good abrasives? There is nothing more than a grinding stone made of diamond powder.

　　Lurik noticed that there was only ordinary whetstone here in Clarvasson, and when he touched it with his hands, it was ordinary sandstone.

　　 Although it is deposited as a huge amount of quartz particles in sandstone, simple silica particles are also good for grinding away. It is not a simple task to grind the blade by simply holding a sword-shaped iron bar with repeated vertical grinding.

　　 Their work is like a traditional kitchen knife in their own impression, and there is no such thing as a simple grinder.

　　 Is there really no grinder?

　　Lurik deeply felt that the Roman Empire must have such equipment as a grinder, even if it is operated by humans, it is more efficient than the manual surface grinding of the sword by the workers.

　　 Could it be that the empire was destroyed, and the technology was never introduced to Northern Europe?

　　Let’s continue to observe first to see what kind of dagger can be polished by the bearded guy Klavasen with the most traditional craftsmanship of the Ross tribe.

　　Lurik once again acted as a spectator, even though there were many ideas in his mind, he said nothing now.

Rurik watched quietly. Although the leader Otto was a little uncomfortable with his son’s insistence on soaking in the blacksmith’s house, he learned that Kravasson really, at Rurik’s request, created a unique color. The worries were also dispelled when the sword was embryonic.

　　 During the five days of Cravason's iron strike, 120 bars of soap were produced there. The soaps are so big that they can be used for a long time after a family buys one.

　　 So, every room began to be filled with a special smell, it can't be said to be smelly, there is even some fragrance.

　　 As long as it is the first time to use it, people who have used it will fall in love with it.

　　 An action sweeping the entire tribe is happening quietly. Many families have a new job in the boring winter-washing their own dirt, and then washing their clothes.

　　 In just five days, the volume of soap in many households has shrunk a lot, all because of excessive use.

　　 So when Otto was patrolling the winding roads of the tribe, a buyer approached him and asked the truth about the fact that the soap was getting smaller.

His explanation is very simple: "sopa is made from mortal objects using the knowledge given by Odin. It is not the inexhaustible holy relic of Valhalla. Sopa will lose some each time it is cleaned, and when it runs out Later, you will find me to buy two more silver coins. I will also ask the priest to make more."

　　 All 120 bars of soap were sold without any change in price. According to the agreement, the priests happily got 24 silver coins. Until now, the "soap workers", mainly Bona, still feel that they have made a lot of money.

　　Actually, Otto is a soap "salesman", he will not earn even a copper coin with his only son. He sells soap as much as possible for his son's future prosperity and status.

　　Lurik has easily earned more than 200 silver coins here, and the wealth of the tribe is being concentrated to the leader's family at an unprecedented speed! Before this, there was almost no commodity exchange between the chief family and the families of the tribe.

　　Although this is a search for Minzhimin Ointment, soap really brings an unprecedented experience. Once you experience the absolute comfort brought by sopa's cleansing of your body and clothing, it is the expensive price of two silver coins.

　　What if my wealth decreases?

　　 Go grab it!

　　 A large number of Finnish tribes on the other side of the sea are where the wealth lies, and they may have been harassed by them in the previous Sorgon sailing. Although the Finns are good at guerrillas, they are very backward in terms of weapons.

　　 They are backward people, and their tribe has not even organized a tribal alliance.

　　 The mighty Ross people can become rich as long as they organize a man to cross the sea and find a certain tribe to **** all the leather goods they have hoarded.

However, the tribes have not organized manpower to attack them actively for many years. It seems that the last action was ten years ago, because the tribesmen fled without resistance, and the warriors found some deerskins and sheepskins in their homes, and a small amount of them. The sheep with big horns has no other value to receive.

　　 Maybe looting them, it's far better to venture south and grab the Finns to make money, but the risk is too great.

　　 Just because of soap, some families in the tribe are ready to move.

　　 Following the leader to participate in the Sorgon in the spring, how much can he get from the Novgorod tribute? Spontaneously organize some people to launch an offensive on the land opposite the sea. Maybe they can plunder a large amount of wealth without risk, and they will be able to use soap for many years in the future.

　　 Otto didn't feel this trend of thought at all, and he couldn't control the spontaneous plundering behavior of his tribe. Just report the action plan to yourself, and after the event is done, take out a part of the spoils to distribute to the people.

　　 Otto felt something else, that is, Rurik and the blacksmiths acted.

　　 He has seen that silver-white sword embryo, it is still brighter than all blacksmiths at the embryonic stage!

　　 If it is polished very sharply, can it really cut off the iron sword? If it can, can the blacksmith Clavasson do more?

　　 At that time, Kravasson was bidding 50 silver coins, and many warriors of the tribe had to take out their belongings, and they had to buy one, and then they would pass this "excalibur" to future generations.

　　 So, how should I discuss with Kravasson the proportion of silver coins earned in the production of "Excalibur" in the future?

　　 Maybe Rurik is already thinking about it.

　　 Now, Rurik is staring at the blacksmith's sword sharpening work, and making money is not something he has to consider now. Starting

　　 The sword can only be successful if it cuts the iron like mud. It must be sharp and hard.

　　It must be hard, because Cravason spent most of the day, using a small grindstone to smooth out the fine protrusions on the sword. The sword was polished, and the bright white metallic color reflected in the sunlight, which was not the case with the previous iron swords!

　　Lurik knows that only carbon steel has such a color!

　　 But it took a lot of time to just do a "skin polishing" for the sword. It takes a long time to sharpen the blade.

Although the efficiency of using emery whetstones is extremely high, the efficiency of ordinary whetstones is too poor. Moreover, the blade to be polished is already high-carbon steel. Excessive hardness will cause the whetstone to grind into dust and make the blade. Grind well.

　　 To make matters worse, maybe Clavasson really doesn't have a manpower grinder.

　　 On the first day of sharpening his sword, Kravasson’s biggest surprise was the reduction of his sharpening stone.

　　 "Oh, what's the matter? I'm very tired, and the sharpening stone I've used for a long time has already left a depression. Lurik this..." Kravasson asked puzzledly.

　　 "Because this sword is very hard, that's why." Liurik said without changing his face.

　　 "Maybe so." The loss of the whetstone was nothing, and Clavassen was very happy that it was the result of the hardness of the sword. Although he was tired, his fighting spirit was stronger than in the morning.

　　 "Okay! I'm old, and I will be the main force of KaVo tomorrow, so I have to rest my shoulders."

　　 Leurik glanced at the confident Kawei, he still didn't talk about the grinder, so let's continue to observe tomorrow.

　　 There will be a grinder sooner or later, because this machine is forced out by the workers in the face of a large number of weapons production.

　　 Ancient Greece and pre-Qin China both spontaneously invented the technology of the grinder, because only in this way can the spearhead and arrow be polished efficiently.

　　 Maybe there will be more time, and Clavasson will have more orders here. Perhaps this old guy or Kawei can get inspiration from the wheels of those small two-wheeled carts of the tribe and invent a grinder that can sharpen swords.

　　 The first day was a boring day, and the second day was a new boring day. The work of the blacksmith is simply sharpening the sword, and the active staff is replaced by Kawei, this strong young man obviously did not make sharpening the sword any easy job.

　　Kawei and Cravason are like two tools of indescribable emotions, just repeating mechanical work all the time.

　　 But this job seems to be a simple repetition, and it is also rich in technology. First release https://https://

　　Lurik couldn't help thinking of two poems, called: grind a sword in ten years, never tried the frost blade.

　　 A good sword will naturally take a long time to polish. Who knows how much effort the craftsman has put into it?

　　 Time has become very boring, since I asked to stay here to wait for the sharpening of the blade to be completed, I should not leave before it is completed.

　　 Three days have passed, and until it was dark, after a large whetstone was worn out, Clavasson's fingers were also blistered for it. At this time, he could finally announce that his work was about to end successfully.

　　 But now, Clavasson is holding back a lot of words because of the different color of the sword.

　　 Panting, he poured water on the second sharpening stone, and wiped off the water marks on the sword and the stone with a linen cloth.

　　 He gently wiped off his forehead and shouted, and asked a straightforward Rurik: "Your sword is finally about to be completed."

　　 "Oh? In three days, you finally polished the blade?" Rurik rushed over excitedly, "Shall we try it now? Go and chop the iron sword?"

　　 "Not yet, the blade needs further sharpening. I have a new question now, maybe your wisdom can answer me."

　　 "What is it?"

　　 "Look at the blade." Kravasson pointed and asked, "Why, the blade is brighter in color, which is obviously different from the back of the sword."

"It's very simple, because the blade absorbs more..." Rurik suddenly wanted to say "carbon". At first thought, the tribe always called charcoal "col", which meant "combustible embers". But what I want to say about carbon is the concept of "carbon" in the Norse language.

Rurik paused for a while and continued: "I will tell you the clear reason, but now, you have to continue to polish it. I am glad that the color of the blade has become brighter and whiter. It will be the key to cutting off the iron sword. "

　　 Cravason tried to calm down, and did not continue to ask the child.

"That's it for today. I hope I can sharpen the sword in two days. Rurik, I must admit that this sword is definitely the hardest sword I have ever seen. In my opinion, when you get the perfect I have lost two or three whetstones when cutting the blade." As he said, a wry smile broke out of Cravason's big mouth.

　　 But Rurik could see from his eyes that the old guy's mood was probably in admiration.

　　 "Well, maybe I have to pay for the whetstone you lost."

　　 "No, this is a necessary expense." He subconsciously patted Rurik on the shoulder: "Good boy, I will succeed before Hanukkah."

　　 Hanukkah is really getting closer...

　　 Four days have passed since the completion of the forging of the sword embryo. On the fifth day, Kravasson had sharpened the blade very sharply. As expected, his second sharpening stone was also scrapped.

　　Lurik guessed that maybe he could get a very high-quality corundum without the embarrassment now.

　　 is just a whetstone, and there is also a lot of knowledge in it.

　　 The best whetstone has become an artificial composite. It is a disc made of diamond powder and a binder. It is the key to a grinder and can grind all steels.

　　 There are also high-quality natural abrasives in nature, that is, corundum that contains aluminum. It is actually a special type of aluminum ore. Because of its hard texture, it is the best polishing material that people can get in ancient times.

　　Since the corundum is not available, we can only use the deposited sandstone to continue to make do with it.

　　Thinking about it this way, maybe sandstone is used to make a wheel-shaped grinder. The most important thing for such a manual grinder is self-wear. It may not be a good choice to use it to sharpen the blade directly, but it may be the most effective way to repair the blade.

Using a flat sandstone whetstone to sharpen the blade, Clavasson has always done this. He also has clear skills in his hands. This old guy is really like a robot. There is no abnormal tremor in all movements and his hands hold the pad. The thick cowhide with the blade was polished forward at an acute angle of about 20°, and there was no movement of backing and polishing at all.

　　 Sword sharpening is a kind of science. If you sharpen the blade, you can only point in one direction. Otherwise, you are causing trouble for yourself.

　　 The blade of the sword is getting sharper and sharper, and the cowhide that protects his hands has been cut with a lot of cracks on the other side of the blade.

　　 I must be more and more careful at work. Finally, after the hide of the handguard was finally cut, the five-day sharpening of the blade can be declared over.

　　 "Liurik, it's all over! It's all over!" Kravasson put down the sword. He didn't have more joy of success. After putting down the sword, he quickly wiped the sweat from his forehead.

　　 "Finally! I have waited until now, can we..."

　　 Lurik hurriedly ran to the whetstone. At this moment, isn’t the dagger customized by himself a magic weapon?

　　 "It should be very sharp, right?"

　　 "It should be ~www.readwn.com~ I am now..." With that said, Kravasson temporarily inserted the dagger with a simple wooden pancake. "Let's try it first and see if we can cut the cowhide."

　　 "Okay! Hurry up!"

　　 Leurik's eyes widened, watching Clarvasson put the cowhide cushion that had been cut in various directions, piled it up three times, and supported it with his left hand, accepting the cutting with the sharp edge of his right hand.

　　 Everything is expected, the sword is very sharp.

　　Looking at this sturdy and resilient cowhide, Clavasson used a little bit of strength. After being folded, he had six pairs of cowhide, and he was shocked by this dagger for a perfect cut.

　　 "Oh! It's incredible! This is cowhide."

　　 "Cowhide? What's the matter? It seems that I have achieved my goal, so I only have to chop the iron sword." Rurik said excitedly.

"Oh my child, you are so cute. You should know that your sword can't be guarded against at least six layers of leather armor. Up to now, any iron sword I build can only cut two layers of leather armor. This short sword, it has created a miracle."

　　 Clavasson's eyes shimmered, looking at the old guy's trembling beard and fiery eyes, Rurik thought carefully, and then looked at his steel sword with a pair of azure blue glasses. It is indeed extraordinary.

　　 "Well, just tonight, just now, I want it Kantie Sword. I hope... its blade will not crack."

　　 "Good!" The excited Clavasson ordered his more excited son Kawei: "You go to the warehouse and grab an iron sword. If you have the greatest strength, I will give you the work of cutting the iron sword."
