A few days later, Lu Bu's reply came to Cao Cao's army, almost without any resistance, Lu Bu allowed Liu Bei to return to the army Xiaopei, after all, Xiaopei's money and food supplies were almost all from Xuzhou, Liu Bei went to Xiaopei, as long as Lu Bu took precautions, he wanted to put Liu Bei to death. Moreover, the most important thing is that Cao Cao still holds the title of 'Xuzhou Mu' in his hands, and for Lu Bu, this Xuzhou Mu is now more important than anything else.

After receiving Lü Bu's reply, Cao Cao immediately sent Liu Bei to Xu, and Liu Bei was also "loyal", and almost without any delay, he waved his army to the southeast. And Wancheng's Zhang Xiu was also after Cao Cao's pacification, transferred to the south to return to Wancheng, for this matter, Cao Ang deeply regretted, I heard that Zhang Xiu is known as the king of guns in the north, and the spear master Tong Yuan taught skills, he originally wanted to ask him for advice, but now he missed such a good opportunity.

After a short rest, Cao Cao turned his army back to Xudu, and when he arrived in Xudu, the weather was already in late autumn. The autumn wind in Henan is also quite biting, but it does not have much impact on a group of homesick and friendly soldiers who have been fighting in other places for a long time. As for Ma Jun, Cao Ang temporarily brought him back to Sikong Mansion as a personal entourage.

"Big brother! You're back! As soon as he returned to his small courtyard, Cao Ang's head suddenly began to swell again, compared to usual, it was almost two bigger. Cao Pi and Cao Zhang don't seem to have changed much in terms of personality, but they seem to have grown taller and thicker than when they first left, especially Cao Zhang, who is too strong compared to teenagers of the same age.

"Why are you here?" Cao Ang let go of the mood of wanting to take a good rest, and smiled bitterly at the two helplessly. Cao Pihehe's thief smiled: "Since I heard that my father's class teacher has returned, my third brother and I have been waiting here for the past few days, so as not to let you run away." Cao Zhang, who was on the side, nodded heavily.

"Childe! You're back. I saw Yang Yuan leading a group of servants in Cao Ang's courtyard to come in a hurry, including the maid Yu'er of the Cai family. Cao Ang nodded lightly, and then asked Yu'er first: "During this time, how is Miss Yu doing in the mansion?" ”

Yu'er bowed down and said softly: "If you have to ask the prince, everything is fine with Yu'er." Cao Ang smiled when he heard this, then turned his head to Yang Yuan and said, "Yang Yuan, clean up a room for this Mr. Ma Jun, Mr. Ma is my heavy guest, remember not to slack off." Also, immediately arrange the wine and food in the hall, and I want to have a few drinks with Mr. Ma. ”

After Yang Yuan took the order and left, Cao Ang said to Ma Jun: "For the time being, Mr. has been wronged first, come, please come inside." Ma Jun came from a humble background, when he was treated so politely, he was not only moved, but also determined to live up to Cao Ang's kindness.

"Brother! Why don't you bring us with you for a drink! Hearing this, Cao Ang hurriedly smiled at Cao Pi and said, "Second brother, the eldest brother has something to discuss with Mr. Ma, you two go to play elsewhere first?" ”

"Why! No, we're going to drink with you too! yes, third brother. Hearing this, Cao Zhang hurriedly said, "We also want to drink!" I saw Ma Jun smile lightly and said to Cao Ang: "The son doesn't have to worry about Ma Jun, even if the two little sons come together, it is okay." Cao Ang said in his heart, Mao has not grown yet, I have to drink, I am doing this for the good of the two of them, no wonder the ancients did not live long, not only married early, but also precocious!

But at this point, Cao Ang was helpless, and the two large and two small ones immediately walked into the hall. When they were young, the wine and dinner were ready, and the four of them began to talk in detail, the two boys had a really large amount of wine, especially Cao Zhang, who could drink more than Ma Jun. After the five flavors of the dish, Cao Pi Cao Zhang asked Cao Ang about the war situation in Huai this time, Cao Ang was impatient, so he had to talk about it for the two of them little by little, Cao Pi was fine, but he saw Cao Zhang's eyes flashing, with a look of yearning and expectation.

"Big brother, you have made a contribution this time, presumably the Son of Heaven will issue an edict to make you a general soon, right?" After Cao Ang finished speaking, he saw Cao Zhang looking at Cao Ang with envy, Cao Ang smiled slightly, and said, "Big brother doesn't know very well. "Although he has received Cao Cao's signal that after returning to Xudu this time, he will perform himself to replace Yuan Shu as the rear general, but for this kind of thing, Cao Ang thinks that it is better not for too many people to know about it.

Seeing Xiao Cao Zhang's longing gaze, he swore in his mouth: "A man was born between heaven and earth, and he should be a gun and a horse, and he will sweep away!" In this way, it lives up to the ambition of a man. But seeing Cao Pi frowning when he heard this, he said: "Third brother, how many times have I told you, since we are the men of the Cao family, we should take the world's society as our own responsibility!" How to learn the way of the horseman. ”

As soon as the words fell, I saw Cao Zhang's rare retort at Cao Pi: "The eldest husband has been learning from Wei Qing and Huo Quai, leading 100,000 troops to gallop through the desert, driving out Rong Di, making great contributions, and establishing a title, otherwise, what poetry and scriptures, books and scriptures, Lao Tzu, and Zhuangzi every day, will you be a doctor of the Five Classics!" ”

I saw that Cao Pi was just about to reply, but he heard Cao Ang smile and said: "Okay, second brother, everyone has their own ambitions, don't force them." Since the third brother has ambitions to be a general and sweep away Hu Nu for the country, you and I should support him, why bother to make it difficult for others to turn their thoughts to him? Third brother, if you have a chance in the future, the eldest brother will join you in conquering the northern frontier and sweeping the desert! ”

I saw that Ma Jun over there also smiled and said: "That's right, the third prince has the ambition to contribute to the country, and Ma Jun should also do his part. ”

After seeing Ma Jun finish speaking, he immediately stood up, took out a few leather drawings from his arms, and then presented them with both hands: "Eldest Prince, please see, these few things can get the mind of the Prince?" ”

Cao Ang took Pitu suspiciously, looked at it suspiciously for a long time, and then suddenly said happily: "It turns out that what Cao Ang said to Mr. before, Mr. remembers it!" ”

Ma Jun said with a smile: "The eldest prince has endless ideas, which has benefited Ma Jun a lot, and this 'double horse pedal' and 'war horse saber' are painted according to the son's description."

In later generations, the earliest unearthed object of Chinese horse pedals was the "single horse pedal" of the Western Jin Dynasty. Since Cao Ang returned to the late Han Dynasty and learned horses, he found that the cavalry of the Eastern Han Dynasty had begun to take on the scale of 'single horse pedals', but the things used were not iron horse shoes, but set up with leather ring locks, although not all good, but also had the effect of single horse pedals.

After the practice of horseback riding, Cao Ang had the idea of making a double horse pedal, but this is not as easy as imagined, and it is not something that you can make by drawing a sketch casually. These include the fulcrum of strength, the shape of the double pedals, the elasticity with the horse's belly, and the balance with the human body.

Therefore, Cao Ang has been paying attention to talents in this area, so much so that when he heard the 'loom' conversation between Ma Jun and the village woman in Bagongshan, although Cao Ang didn't know the reason, he subconsciously patiently asked Ma Jun, who would have picked up such a treasure as Ma Jun, a mechanical master!

Ma Jun lived up to Cao Ang's expectations, and under Cao Ang's subconscious infiltration, Ma Jun immediately began to draw a sketch of the 'double horse pedal', along with the Mongolian riding sword that Cao Ang had mentioned to him.

The cavalry knife of modern Chinese cavalry is a reference to the Mongolian cavalry scimitar transformed by Genghis Khan, the curved part of the blade is long and extended, and the part near the handle is very straight, much longer than the general scimitar part, so as to ensure that the cavalry does not injure themselves when they come and go in conflicts, and also saves a lot of physical strength for themselves when sprinting to grip the handle.

These things, for Cao Ang from the postmodern era, there is no problem in narrating, but if it is a drawing production, it is impossible without professional means and technology.

Next, Ma Jun replaced Cao Ang to explain the functions and utility of these two things to Cao Pi and Cao Zhang, Cao Pi was nothing, Cao Zhang's eyes were shining, and he kept asking this and that, and after a long time, Cao Ang had to interject emptyly: "Deheng, can these two pictures be regarded as finished products?" ”

Ma Jun shook his head and said: "According to what the eldest prince said, the drawing is drawn, but if you want to put it into practice, you still need to create these two things, and then adjust it carefully, according to practice, it will take at least two months to complete." ”

Cao Ang nodded when he heard this: "Deheng just do it, I will instruct Yang Yuan to take care of all the manpower needs for you." When Ma Jun heard this, he immediately bowed: "Don't worry, Ma Jun will live up to high expectations!" Cao Zhang, who was on the side, hurriedly said: "If Mr. Ma has anything to help, I can also help Mr.!" Cao Ang and Ma Jun couldn't help but laugh when they heard this, and then looked at each other and smiled.

Soon after instructing Yang Yuan to arrange production and iron materials for Ma Jun, Cao Ang received a message from Cao Cao sent from the Chinese army, ordering him to participate in the court meeting four days later, and wait for the Son of Heaven to be crowned a marquis!

(Actually, I don't want to write about the shoeboard and the saber, because it's already written badly, and everyone is too lazy to read it, so I don't want to describe it more.)
