Ancient China's cadres Mo Xie and his wife were sword casting masters, and the cadres were ordered by the king of Chu to cast the sword, and the casting could not be achieved for a long time, and his wife Mo Xie helped her husband, so she jumped into the sword casting iron water on the day of the sword, and the sword was completed.

What came to Aarold's mind was this ancient Chinese story, he read this story and consulted other books at that time, the Chinese in the fifth century AD had already understood that to cast a good iron sword, some other substances must be added, the most mysterious of which is human blood, so there is the legend of blood sacrifice sword, in fact, in the final analysis, because human blood contains many other trace elements, this trace element in the casting process into the molten iron increases the hardness and toughness of the iron sword.

"It's tree sap, as long as it is cooled with honey or plant sap during cold forging, you can forge a good sword." Arold did not tell the old man to use the method of blood sacrifice, because this method would lead to other extreme things, and according to his research in his previous life, the effect of using plant juice and nectar was actually the same.

"What? Is that so? There was a strange glint in the old man's eyes, and he stretched out his withered hand and grabbed Arrod's arm, his face almost touching Arold's face.

"Father, please let this lord go." In a panic, Orn hurriedly stepped forward to break his father open, he was afraid that his crazy father would provoke the nobleman with the sword.

"It's okay." Arrud waved his hand very calmly, he knew that when his mind entered a dead end, someone suddenly opened a door to another world of knowledge, and that kind of supreme joy was beyond the experience of others.

Suddenly, the old man fainted without warning in Arrod's arms, which scared Arrod a lot, he subconsciously wanted to take out his mobile phone to take pictures and keep evidence, and suddenly remembered that this is the medieval mobile phone gods are all floating clouds, what can be done, what if it is false, but fortunately, people in the Middle Ages did not have the vice of the old man who fell and did not dare to help. On the contrary, Ou En was embarrassed to explain to Arrod that the old man had been working for a few days and nights, and had been supported by a spirit of exploring techniques, and now when he heard that Arold had uncovered the mystery, his heart was relieved and his body immediately fainted from exhaustion, so he did not mean to offend the nobleman at all.

"Lord Arrod, this is all the fifteen hats and helmets and three pieces of leather armor that I have kept." When night fell and the bells rang from the church in the castle, Orn personally sent the hat and helmet to Arold's camp, and in order to thank Arold for the secret casting technique that Arold gave his father, Orn sold the equipment to Arold almost at a very low price, and said that his father was going to start forging a sword made of Arrod's secret art, and if it was successful, he would give it to Arold as a thank you gift.

"Well done Arrod, I don't know how you got that blacksmith to give us so much equipment, but you're really capable." Holding a glass made of ox horns, Yves drank the ale in it and exclaimed to Arold that the two brothers' relationship had gotten better and better since they fought side by side.

"Arold, did you go to the bazaar and find anything to buy?" Sir Wendell also stepped out of the tent and stretched, the sword hanging from his belt clanged on his body, and the abundance of funds made Jazz in a very good mood.

"Yes, it's the kind of goods that Yves has in his hand." Arold pointed to Eve, and said to Sir Wendell.

"What?" Yves looked at the wine glass in his hand suspiciously, and didn't understand what Arold meant, could it be that Arold couldn't do the business of wine glasses?

"I found that many merchants in the bazaar were selling ale, and the ale here seemed to be very cheap." Arold ignored Eve, and told Sir Wendell what he thought, and indeed he didn't know why there were many merchants selling barrels of ale in the bazaar, they must have received the news of the army's build-up and collected ale from all over the Holy Roman Empire, wanting to make a lot of money here, but what he didn't expect was that there were too many people selling ale in the bazaar, and as a result, the supply exceeded demand, and the price of ale fell all the way.

"But the price of ale is so low that if we buy it, how can we sell it again, because even local merchants refuse to buy it." Yves shook his head and felt that Arrod's idea was unrealistic, and indeed what Yves said was true, but Arold didn't think so.

"Let's bring these ales, I reckon the Duke of Mason is about to lead us on the march, and the troops will definitely consume a lot of wine on the way, as long as we sell the wine to friendly troops, we will definitely make a lot of money." Arold smiled and said, the boring military life has caused many soldiers to suffer from alcoholism, they can go without food for a few days, but they can't go a day without drinking, and the knights and the light infantry can't do without ale.

"Oh, how do you know that Duke Lu Dao is about to go on an expedition?" Sir Wendell asked curiously, since Sir Able visited and confessed to Arrod's life-saving grace, Sir Wendell felt that his little son was unpredictable.

"Ha, so many troops are gathered here, although the food is all provided by us, but the duke also has to provide a part, which is nothing for the wealthy Herman family, but if this is the case for a long time, the granary in their castle will be quickly emptied, rather than this, it is better to send us to fight quickly, at least the food will not have to be borne by the duke after sending it on the road, and you can still grab food on the spot after entering the enemy's territory." Arrod said as he analyzed.

"That's right." Sir Wendell nodded, relieved that there was finally a child in his family with a brain.

Arold was right, but Duke Mason did not rush to send the gathered vassal troops on the road, Duke Mason had his own plan, he wanted to kill the hated Duke of Saxony for a long time, and even thought that in the last Imperial Diet, if it wasn't for the damned Duke of Saxony against himself, the title of emperor of the Holy Roman Empire would have fallen on his head, and he should be a veritable Caesar, not the Henry who only knew how to catch birds all day long, and it is said that when the elected emperors voted for him, Henry was still hunting canaries in the forest. Therefore, the Duke of Mason decided to concentrate all his strength, and it was best to kill the Duke of Saxony's troops at once and capture the Duke alive, even if he could not kill the Duke of Saxony, he would have to die in prison, and would never accept the ransom, even if it would damage his honor, and he was even already thinking about which torture instruments would be more appropriate.

"Isn't my father ready?" A few days later, Sir Able and General Ralph strolled through the bazaar, with two sword-wielding guards in front of them and behind them, and life in the castle was dull and not at all lively and interesting, Sir Able took General Ralph out of the castle under the pretext of patrolling the law, and they chatted as they went.

"Yes, the duke thinks that we are not enough, and he has gathered some more vassals from the border, supposedly horse breeders who are good at raising horses." General Ralph looked around casually, answering Sir Abel's questions while also paying attention to the security around him.

"Ha, my father is too cautious, but the Saxons are really difficult to deal with, and we have lost the upper hand in several border encounters." Sir Able was in high spirits, and he looked at this and saw that busy with joy, and at that moment he saw a blacksmith holding a sharp sword, which was very ordinary, but the blacksmith did something unusual, and saw that the other blacksmiths seemed to be shouting something unconvinced, and the blacksmith with the sword did not say a word, and raised the sword and slashed at a hanging iron sickle, and with a crisp sound, the hanging sickle was broken in two.

"It can't be, where did you get the Milan sword." The other blacksmiths gasped and said in an incredulous tone.

"Good sword, is this yours?" Sir Able stared at the sword in the blacksmith's hand, a knight's love of weapons and equipment was almost instinctive, and unlike his intrigue father, he was a good man who liked to fight under the sun.

"No, no." The young blacksmith was none other than Orn, and he held in his hand a sword made by his father himself according to Arrod's secret technique, and when he was cold forged, he used honey water, although it was a little extravagant, but the effect was really good, and the forged sword was exactly the same as the Milanese sword, no, it was stronger than the Milanese sword in some ways.

With the sword in hand, he was going to go to Arold and give him the sword according to his father's request, but he could not stand the ridicule of the other blacksmiths, and the young man impulsively picked up his father's bloody sword and cut the farm implements.

"It's not yours, then who made it, call him out." Ser Able asked eagerly, his eyes completely drawn to the strange luster of the blade in Orne's hand, and if it weren't for his identity, it would have been as if he had snatched it from the young blacksmith's hand to take a closer look.

"My lord, my father and I made this sword." Orn replied honestly, with a slight panic in his tone, for his body had been framed by two guards on either side, and the fool could see that the nobleman in front of him was not small.

"Oh, then you can make an offer." Sir Able breathed a sigh of relief, as long as it was something sold in the blacksmith's shop, he was ready to buy it at any price, and it was not a big deal to sell some of his own silverware.

"But this sword already has an owner." Embarrassed, Orn clutched the sword in his hand and said to Ser Able.

"What? Who bought it? Sir Able's face immediately turned pale, his slender eyebrows twisted together, and he immediately inquired of Orne.
