When Cao Cao was resting, Cao Ang replied yesterday noon that the core members of the "Sikong Party" would come to the palace today to discuss the crusade against Yuan and Lü, as well as how to deal with the Han Emperor's plan of "sacrificing his life to feed the tiger".

I saw Cao Cao walking into the garden, stretching his waist, and the afterglow in his eyes caught a glimpse of Cao Pi walking weakly towards him, looking at Cao Pi's "pitiful" appearance, Cao Cao couldn't help sighing in his heart, sorted out his emotions and asked with a smile, "Pi'er, what's the matter?" ”

The latter bowed respectfully and said, "The child does not dare to speak. ”

Cao Cao smiled helplessly, waved his big hand and said, "But it's okay to say." Although Cao Pi hesitated a little, he still said to Cao Cao according to what Mrs. Bian taught him today, "Father, since my eldest brother came back, you have not come to tutor me in my schoolwork. ”

Mrs. Bian has been grounded by Cao Cao at present, and is not allowed to go out of the room for half a step, although she has not stated it publicly, but she has made a punishment in essence, and she wants to teach her a lesson, but she still doesn't give up, and she picks up Cao Pi to find Cao Cao, nominally through Cao Cao's feelings of cherishing his heirs, and enjoying the family of father and son together, but the actual purpose is self-evident.

And seeing the cowardly Cao Pi, how can Cao Cao think so much? After all, it is his own son, how can Cao Cao be too biased?

Cao Cao stroked Cao Pi's head, the latter was quite useful, enjoying the belated silence, raising his hand to move, and finally hugged Cao Cao's waist tightly.

Cao Cao said with pity in his eyes, "Pi'er, you don't have to think too much, for my father's recent heavy affairs, when I am too busy to be free, I will definitely take a good test of you." ”

Cao Pi listened, with a smile on the corner of his mouth, how could he not allow him to nod heavily. As if he would regret it if he agreed to Cao Cao a step later, he just wanted to let Cao Cao test his own oil head to be intimate with his father, but he didn't want to be interrupted by an "uninvited guest".

"Old man, old man." Hearing the sound, Cao Pi was stunned when he saw the comer, Cao Cao followed Cao Pi's eyes, and his face was full of black lines.

Looking at the place where the sound went, he saw a burly man with a dignified appearance walking in front of him, with a disheveled head, shirtless, tall and strong, strong arms, beautiful muscles, steady steps, and a body as strong as a wall.

The person who came was Cao Ang, and I saw him holding a new thing in his hand and walking towards Cao Cao.

Cao Pi saw that someone was coming, and he hurriedly loosened his father's waist, and said respectfully to Cao Angzuo, who was approaching, "Pi, I've seen my father and brother." ”

Cao Ang was stunned for a moment, then smiled and said, "It turns out that the second brother is also here." He looked at Cao Cao and said, "Is there something wrong with the two of you?" ”

Cao Cao looked at Cao Ang helplessly and said, "Although you are at home, you should also pay attention to your appearance, and instead of building a river embankment or building a city, why do you walk shirtless?" As an eldest brother, you have to set an example in front of your younger brothers, what do you look like? ”

Cao Ang rolled his eyes when he heard this, grabbed Cao Cao's shirt with his sweaty big hand and said, "It's just right, you two go to the workshop I built next to the stable, there are good things for you to see" grabbed one person with one hand and "held" him and staggered towards the workshop.

As soon as I arrived at the stable, I heard the sound of metal knocking, "Who's banging?" Cao Cao asked.

"You'll find out when you go." Cao Ang dragged the two of them to the workshop, saying that the workshop was just a pavilion with a straw hut, and in the pavilion, I saw Cao Zhen also shirtless, with thick abdominal muscles, waving powerful arms, and skillfully hitting the red iron with a hammer. As Cao Zhen's gravity struck, the reddish iron began to deform.

Cao Pi looked around, and saw a small pile of deformed iron blanks piled up in the corner of the workshop, which was obviously a failed product that he didn't want, and said to Cao Ang, "Why did my father and brother smelt iron here with Brother Zidan?" Cao Ang bought the guanzi and said with a smile, "You'll know later." ”

After Cao Cao put his hands on his back, he called out, "Zidan, stop." When the latter heard the sound and saw that Cao Cao was coming, he put down the things at hand, took a handful of water in the water tank on the side quite vulgarly, wiped his upper body full of sweat beads, and walked to Cao Cao's side to make a luggage and said, "Father, what's the matter with calling the child?" ”

Cao Pi waved at Cao Zhenzuo again and again, "Pi, I've seen Brother Zidan." Cao Zhen smiled and nodded at Cao Pi, and Quan responded.

Cao Cao bowed his head and asked, "Why are you here?" Cao Zhen glanced at Cao Ang, saw that he nodded to himself, signaled that it was okay to say directly, and then said to Cao Cao, "This morning, my brother came to the room to look for me with a drawing in his hand, and said that it was painted by painstaking efforts last night, and found his son to help him to see if he could make the things on the drawings." Cao Cao understood, turned his gaze to Cao Ang and said, "What are you painting and doing?" ”

Cao Ang smiled mysteriously and presented the object in his hand to Cao Cao, "Look, this is it." Cao Cao and Cao Pi looked closer, and saw Cao Ang introduced, "I call this thing a bilateral stirrup, which is a pair of pedals hung on both sides of the saddle for knights to use to step on horses when they get on the horse and when they ride." ”

"This thing can not only help people get on the horse, but more importantly, it supports the rider's feet when riding, so as to maximize the advantages of riding a horse, and at the same time effectively protect the safety of the rider." Cao Cao's eyes lit up when he heard this, he nodded again and again, and said in his heart, if it is really as Cao Ang said, then this thing is not simple, it can further liberate the hands of the rider, and it is more convenient to fight immediately, and its appearance is of epoch-making significance to a certain extent!

Cao Cao asked a little eagerly, "Have you ever tried it?" Cao Ang smiled and said, "Why is my father so anxious, and what else." ”

As he spoke, he nodded to Cao Zhen, only to see the latter take out a thing from the stove with both hands, so he listened to Cao Ang continue to introduce, "This thing is called the Takahashi case, fixed on the horse, and with the stirrup, it can be better relayed on the horse, free your hands, and further strengthen the mobility and flexibility of the cavalry." As he spoke, he took out a crescent iron and introduced, "This thing is called a horseshoe, also called a horseshoe." Is "Cao Cao's eyes brightened" nailed to the horseshoe for use? Cao Ang nodded, signaling that what Cao Cao said was correct.

A horseshoe is an iron hoof-shaped object that is attached to a horse's hoof. The horse's hooves are composed of two layers, the one that touches the ground is a thick and hard horn, which can be understood as a fingernail, and the upper layer is a living horn. The horse's hooves are in contact with the ground, and they will fall off quickly due to the friction of the ground, the corrosion of stagnant water, etc., and the main purpose of nailing the horseshoe is to delay the wear of the horse's hooves.

The use of horseshoes not only protects the horse's hooves, but also makes the horse's hooves grip the ground more firmly, which is good for both riding and driving! Cao Cao had been on the battlefield for a long time, and after a little introduction by Cao Ang, he already knew what it meant to make these three things, and to put it bluntly, it could determine the outcome of a war.

Immediately ordered, "Get to the school yard quickly, load the equipment for the horses, and I want to see how it goes!" ”

I saw that on the school field, Cao Ang and Cao Zhen matched the three things for horses, Cao Zhen nodded to Cao Ang, and motioned for himself to experiment. There were many onlookers on the school field, all curious about what the two had placed on the horse, but seeing Cao Zhen, stepping on the stirrups, turned over on the horse quite easily, and began to gallop in the neighing of the horses.

I saw that his feet were on the stirrups, and after the help, his upper body was fixed as if he was sitting, stable as a rock, and he could gallop without holding the horse's neck tightly to stabilize his body, and the onlookers couldn't help but be surprised.

But seeing that Cao Zhen was still able to bend the bow and arrow steadily in the gallop, the bow was like a full moon "chirping", and the arrow burst out, and the arrow was forcefully submerged into the target! "Right in the bull's-eye." A target officer shouted. Seeing this, Cao Cao stroked his beard and laughed: "Zi Yu is really my family's thousands of miles, and Zidan is also a thousand miles away!" "I believe in my heart that as long as we start mass production of these three things, after the generals and soldiers under my command are familiar with the operation, the combat effectiveness will definitely increase. I couldn't help but glance at my eldest son again.

But he didn't notice that Cao Pi lowered his head deeply, his hands clenched into fists, and he was quite unwilling, "Big brother, there are too many places to crush yourself, why do you want to monopolize your father's favor?" "For a while, hatred and unwillingness...... and other negative emotions have surged into Cao Pi's heart, the seeds of hatred have sprouted in his heart, and even seeing Cao Ang's gaze is a little unkind?

"Mother is very right, he deliberately relied on his status as the eldest son, and relied on these strange and obscene gadgets to monopolize his father's favor, and I can't let him succeed."

Cao Pi thought so frantically, Cao Ang seemed to be aware, and wherever he looked, he saw Cao Pi looking at him with a smile full of reverence, but after Cao Ang's eyes swept over, Cao Pi's expression immediately changed suddenly, very eerie and terrifying, endless chills appeared in his eyes, and there was even a trace of murder!

Mrs. Bian's remarks and demagoguery finally came to fruition after a long period of "unremitting efforts", which made Cao Pi blinded by hatred, thinking that as long as Cao Ang disappeared, he could regain his father's preference for herself, I don't know if Mrs. Bian would be relieved or afraid to see such a hateful Cao Pi? This is not known. The hatred has been achieved, and the killing machine is revealed!

"After today, I will give this refining method to the workshop and let them make it in batches." As if thinking of something again, he whispered in front of Cao Cao, "I have also developed a new smelting method, if it succeeds, it can also improve the sharpness of the blade and the defensive power of the armor, that is, the refining time can be greatly shortened." ”

When Cao Cao heard this, he couldn't help laughing, and said in his heart, "God help me, why don't you take this opportunity to build a cavalry unit comparable to the Xiliang Iron Cavalry?" I don't know if it's possible. ”

Cao Ang seemed to know what Cao Cao was thinking, "I can't say that I can carefully build a cavalry unit." After a pause, he said, "What's the name?" At this time, Cao Pi said: "It's better to teach the tiger and leopard to ride." Hearing Cao Pi's words, Cao Ang couldn't help but glance at Cao Pi with deep success, why did he bring it up? Shouldn't it be Lao Cao?

"Tiger and leopard riding?" Cao Cao stroked his beard and tasted it, nodded and said, "Yes, yes, this name is very good." Cao Ang's eyes are profound, and he has contributed to the early birth of the world-conquering tiger and leopard ride, and I don't know if it's good or bad?

There are a lot of thoughts in my heart.
