Master You said: "This dagger is still suitable for use in hand-to-hand combat, according to a certain point of view, scouts can be equipped, and the rest can be taken from its idea and added to the existing weapons." ”

That's insight!

Warfare in the age of cold weapons is not the same as the age of hot weapons. What is suitable for the era of hot weapons is not necessarily suitable for the era of cold weapons.

The Tang Dynasty had horse farms and cavalry battles, and they were suitable weapons for horse warfare and cavalry. In the Song Dynasty, the loss of the sixteen states of Yanyun led to the loss of the land of horse grazing in the Song Dynasty, and the lack of war horses naturally brought about the reform of combat weapons. In later dynasties, it was because of lack of money.

Xue Lang said: "Master You can see what you can use, just use it." ”

Master You nodded, flipped the dagger in his hand, looked at it carefully, looked at it, and suddenly said "Huh", "The craftsmanship of this dagger is amazing!" The color of the outer layer is not the original color, what is the doorway in this? ”

Xue Lang scratched his head, he really didn't understand these, so he could only pick up the things he had roughly understood and said: "It seems that there is a layer of film on the outside, which can not only prevent rust, but also prevent corrosion, making the dagger more durable." I heard that something called chromium and nickel was added. ”

Master You stepped forward and couldn't help but grab Xue Lang's arm excitedly: "Chromium? Nickel? What's that? ”

Xue Lang patted him and said, "It's a metal, I heard that it is an associated ore in the lead mine, but I don't know much about it, I haven't understood it."

Master You sighed: "Oh, why don't you understand!" Since Xue Zhubo likes knives, he should know more. ”

Xue Lang humorously replied: "Master You, you like to eat eggs, do you still want to study how eggs are laid?" ”

Master You was speechless by him, and he held the dagger and studied it.

After spending the afternoon in the workshop, it was time for dinner before Xue Lang went home. In the bumps of the carriage, Xue Lang suddenly thought, I don't know how Master You's iron-striking skills are, I don't know if I can help him make a steering bearing?

It immediately occurred to me that even if there were bearings, how to solve the friction problem? There's no butter right now! By the way, how is butter made? Looks like a petrochemical?

……

Well, Xue Lang's thinking has diverged again!

By the time he returned to Tingfeng Yuan, his thoughts were already crooked to the point of leaving a last word for future generations, so that they could work hard to enclose land in Siberia, occupy all the future oil-producing land in advance, and then wait for the comfortable days of lying at home and counting the money.

This divergent thinking is simply boundless.

Before entering the door, Wan Fu came to report: "Yu Langjun, Ma Duwei and his son have come to visit with gifts, and they have been waiting for Langjun for a long time." ”

"Who?"

Xue Lang didn't react for a while. Changjian hurriedly reminded softly: "It's Captain Ma San Baoma." ”

Xue Lang reacted at this time, and said as he walked: "It turned out to be him, why didn't you come to report to me?" ”

Wan Fu said: "Back to Lang Jun, Ma Duwei said that he came for private matters, and he should not disturb Lang Jun to do official business because of private affairs, stop the small ones, and not let the small ones go to report." ”

Xue Lang nodded, walked in quickly, and sure enough, Ma Sanbao and Ma Yuanliang were sitting in the outer hall drinking water silently, and Ma Yuanliang's face was blue and swollen. Xue Lang walked in with a smile, hugged his fists and said: "Captain Lao Ma has been waiting for a long time, is it Xue Lang's, forgive me, forgive me." ”

Before Ma Yuanliang could answer, Ma Sanbao had already stood up and said with a smile: "Youyang is busy with official business, Ma came here for private affairs, how can you let Youyang abolish the public for private reasons, isn't that Ma's sin?" Son, I haven't come to see you Uncle Xue yet. ”

Ma Yuanliang came over honestly and saluted: "The little nephew Yuanliang has seen Uncle Xue." ”

Xue Lang held him up: "Ma Duwei, Shiro, please take a seat." I'm so familiar with Shiro that I don't need to be so close, but, Shiro, what's wrong with your face? Don't tell me it was a fall, the average person can't fall with such a unique injury. ”

Ma Yuanliang bowed his head in shame, Ma Sanbao stepped forward, hugged his fists and saluted Xue Lang: "A certain family is ashamed to see Youyang!" This son of a wive! Yesterday, Her Royal Highness Princess Lao asked, and only then did she know that this son of a scumbag was fortunate enough to learn a unique method of military training with Youyang! For such a major matter, this son of evil did not say a word, concealed it and did not report it. Although a certain person is from a humble background, he also knows the rules of etiquette, and Youyang treats a certain son so much, and the son does not want to repay, so he is so confused, it is a certain godson who is not strict, and a certain heart is very ashamed. ”

Xue Lang understood, and said with a smile: "Captain Madu, it's a trivial matter, it's not worth beating a child." Looking at the blue nose and swollen face, come, sit down. ”

Ma Sanbao sat down, but he glanced at Ma Yuanliang and scolded: "Son, the prince of heaven and earth, don't you understand?" Although Youyang has no name of master and apprentice with you, he has the reality of master and apprentice, how can he be treated with the courtesy of uncle and nephew! ”

Ma Yuanliang was scolded by his father, and immediately changed his etiquette and changed his disciple etiquette. Ma Sanbao said: "Although Youyang doesn't mind, we can't ignore the etiquette. My own family knows my own affairs, I'm a son of evil, dull by nature, not a talent to lead soldiers, only better than doing things in a down-to-earth way. Youyang passed on his method of military training, which is equivalent to giving him the ability to settle down and establish his life, such a great grace, the son of a sin actually did not tell his father, it is really underwhelming! Son, don't come and kneel yet! ”

Ma Yuanliang, a young man, immediately knelt down with a "plop", Xue Lang couldn't understand what medicine was sold in the gourd of the Ma family's father and son, and didn't want to be gifted, so he hurriedly reached out to help Ma Yuanliang: "Shiro doesn't need to kneel to me, I can't afford this big gift, hurry up." ”

Ma Sanbao grabbed Xue Lang's hand and said, "You Yang can accept this gift." You passed on his ability to settle down, and he should have treated him with the courtesy of a son. It's just that the son of a sinister is dull, and he can't pass on the true inheritance of the young yang, and now that he has this method of training, it is enough. My Ma Sanbao has been in my life, and my grievances are clear, how can I not repay such a great kindness! Therefore, from now on, Shiro will treat Youyang like his own uncle, and if Youyang has anything that needs to be called, he can be called. Son, don't bow yet! ”

Now Xue Lang understands! Ma Sanbao brought his son over to thank him, and then took this opportunity to pull the relationship with Xue Lang, not for anything else, but for his son Ma Yuanliang, who obviously can't lead troops to fight.

Pity the hearts of parents all over the world.

Xue Lang said: "I really don't have to make such a big gift, I am cheeky to say, although I have not yet started a family, but I am actually not much older than Shiro, and I became his uncle who took advantage of the seniority, and now I have to receive such a big gift, how can I afford it?" Get up! ”

Ma Sanbao held Xue Lang's hand, shook his head with a serious face, and said, "Youyang deserves it!" For Youyang, the method of passing on the training of the son of evil is just a convenient one, but the son of evil has really received the teachings and favors of Youyang, how can he be ungrateful because of Youyang's casualness! Son, don't bow yet! ”

So, Xue Lang was almost forced to accept Ma Yuanliang's salute-

Although he felt embarrassed, the respect of the ancients for the teacher made Xue Lang quite useful. So, the second cow who wanted to exchange the reward for the opportunity to learn the arts, was he actually bullying him as an outsider? It's no wonder that Wan Siming looked down on Erniu's master and apprentice very much, thinking about it, there must be their little plans.

People's hearts, it's really complicated.
