About almost a hundred steps, more than a hundred meters. The distance is not close, and people with slightly poor eyesight are estimated to be unable to see the radish clearly at such a distance, and the god arm hand in the army can't shoot so far away; But Guo Shao knew that he could, at least not miss the target.

The air was very cold, Fu Ermei's eyelashes trembled slightly, she held her hand in front of her mouth, pursed her light red and smooth lips, and looked at Guo Shao with a smile.

Guo Shao ignored her for a while, and jumped back and forth a few times in a very funny posture, moving like a frog, this action almost didn't amuse Second Sister Fu. But when she saw that Guo Shao had no smile on his face, she couldn't help but laugh, but just watched him do those actions with interest. He stood and twisted a few more times as if he were dancing, shaking his limbs and letting out a long breath.

"Knock, knock......" Guo Shao clearly felt his heartbeat, and he felt a little bit after some activity. Don't think too much about it, he meditated.

The sound of his heartbeat was like a faint drum music accompanying him, and he followed the rhythm of his heart; The pale white mist wafting leisurely in the cold air seems to be the embodiment of melody. Guo Shao muttered, "Everything is perfect. He gently took the arrow from the quiver, and every movement was calm, neither slow nor fast. With the bow and arrow, the muscles of the whole body were suddenly full of strength, the strong bow was pulled away in great strength, and the tendons of the cow rattle sounded softly in the tension, as if there was a life whispering: Born to fight!

The arrow is aimed and paused in the air, and the most appropriate moment is only by self-awareness. Don't be in a hurry; It should not be too slow, it takes a lot of physical strength to keep the bow full, and it is easier to deviate from exhaustion.

"Smack!" The off-string arrow pierced the air with a rapid pace. The black shadow flashed, and the radish was in the middle! The turnip is tossed off the target by inertia.

"Shot!" Second Sister Fu stroked her palms and said happily.

Guo Shao smiled and lowered his bow. Second Sister Fu stepped forward, held his hand and said, "You can shoot so far, you just reminded me of playing a difficult tune......

"It's back in shape." Guo Shao took a long breath and turned his head to say to Second Sister Fu.

Second Sister Fu said: "Husband doesn't have to go into battle in person, he is still so nervous about his martial arts." ”

Guo Shao said softly: "In this world, I found that most things are not needed, but I rely on them to realize my dreams. I'm not going to abandon it, just as it's always been reliable in countless battles. People only see me in high positions and become powerful, but few people are interested in how I got to where I am now, maybe by luck, maybe by ...... Your sister. He smiled.

"My sister won't choose you for no reason." Second Sister Fu was thoughtful and said quietly.

"There is also a second sister." Guo Shao said, "There is a sentence that I wanted to say when I first met you, but I haven't said it yet." I've done a lot and thought about it for a long time before I'm qualified to be close to you. ”

Second Sister Fu thought about it and said with a smile: "It turns out that you have been thinking about others for a long time. ”

Guo Shao laughed out loud and said, "In the end, you still didn't escape from my palm." ”

Second Sister Fu said softly: "I'm just waiting, when did you say you were going to escape?" ”

…… Guo Shao gradually came out of the guilt of the second sister Fu, and he slowly found a way to get along with the second sister. In front of the palace to take a leave of absence for three days, at first his plan was to accompany the second sister, but he didn't say it, and he didn't want to show the mentality of compensation too obviously.

For three days, he was indeed by the side of the second sister, and he didn't even separate a step.

Three days later, he began to build a blacksmith shop in the middle courtyard, and called a few stout women and the blacksmith Lao Huang to help buy materials. Of course, the second sister doesn't know how to do this kind of work, but she is very interested in what Guo Shao does, and is busy serving tea, water, and food, and watching him work.

The second sister wants to get tired of being by his side at any time, but she won't pester him, she is most interested in Guo Shao's thoughts. As she said, wanting to know more about Guo Shao, the second sister seems to be a little addicted and sees Guo Shao as her world.

He has experience in opening a blacksmith shop, and Huang Blacksmith is also an experienced blacksmith who has been working all his life, and now Guo Shao doesn't have to worry about the cost and what he needs, so he can ask Huang Blacksmith to buy it, and he is familiar with building bellows, shops, anvils and other facilities. However, I have to go to work in the morning, and I only come back in the afternoon to work.

"Yulian's soup." Second Sister Fu took Yulian to the separate house in the middle courtyard that was used as a blacksmith shop, and added in a low voice, "I helped out, learn from Yulian." ”

Guo Shao took the towel from her hand and wiped her sweat, and looked at Yulian silently serving soup, so he smiled: "I remembered a joke." When Liu Bang was poor, he asked Fan Xu, what do Brother Fan want to do when we have money? Fan Xu said, I want two bowls of soy milk at a time, drink one bowl and pour one bowl; Eat pancakes, eat one and throw one, hum! ”

Yulian handed over the soup, and Guo Shao deliberately touched her hand: "Isn't it funny?" ”

Yulian's face turned red, she quietly glanced at Fu Ermei, and muttered: "I think Ah Lang is the same as Fan Xu, why are you still doing this kind of work now?" ”

Fu Ermei smiled: "No, the husband is Liu Bang." ”

Guo Shaogan laughed, speechless. Second Sister Fu said: "But Liu Bang and Fan Xu have such a conversation? Did Tai Shi Gong write it, why haven't I read it...... It must have been made up by the husband. Guo Shao smiled: "So it's a joke." ”

After the two women returned after delivering the soup, Guo Shao worked for a while and didn't finish until it was dark.

He returned to the inner garden, and Second Sister Fu said at the door: "Husband, I asked someone to boil the water, and you can bathe and change your clothes later." Guo Shao nodded, took the second sister into the room next to the living room, and turned out a steel plate from a pile of weapons. He picked up a sword and knocked it a few times, then turned back to Fu Ermei and said, "Don't look at it ugly, I took it to participate in the Battle of Gaoping and the Battle of Wuzhen Town." ”

"The husband built the blacksmith shop to make another pair of armor like this?" Second Sister Fu asked.

Guo Shao said: "I have to think about it again, but I can ask others to do it for me." I'm going to make a new kind of armor...... This piece is not good, it is too heavy, it is a piece of hammered iron plate hanging on the chest, and ordinary soldiers can't use it. We need to think about it again. ”

At this time, Dong Sanmei went to the door and said, "Ah Lang, the hot water is ready." ”

After hearing this, Guo Shao took Fu Ermei out of the house. After taking a shower and eating, at night he turned the lamp in front of the desk and turned out the drawings and pondered for a while. He drew a few plates of armor according to his imagination, but he thought about it for a while and felt that the process was difficult to achieve.

He was not very good at metallurgy before, and only knew some common sense, but he knew a lot about the work of a blacksmith at that time...... The current process can't do what is on the drawings.

In this era, iron-making tools are nothing more than casting and forging. The cast one can achieve more shapes, but the strength is not enough, it is very brittle and thick; Forging is a popular method of manufacturing weapons and armor. Repeated forging, not only can remove impurities, but also adjust the carbon content of iron, good craftsmanship can be beaten into steel, as the so-called "100 forging into steel", such as weapons are by repeated forging, but the efficiency is low.

However, most of the moldings cannot be achieved by hand forging, and it is especially difficult to process large parts.

Like Guo Shao's painting, it can't be forged at all. He changed it a bit, and felt that the main thing in the battle formation should be to protect the front chest, and make a cuirass first...... However, it is still difficult to forge the whole piece with a hammer. If the efficiency is too low, it is better to use the current popular ring chain mail, which is more convenient to move...... What if stamping? Guo Shao reached out and put it on his chin.

Second Sister Fu took the picture he put next to her, and looked at it seriously. Guo Shao ignored her and continued to pick up the pen and scribble some gears and pulleys on the scratch paper.

He casually wrote on a piece of paper: hydraulic forging machine. But think about it, it's hard to find a place to test it now, the river is freezing in winter, and I haven't studied hydraulic transmission before. What's more, what can be achieved by water power can also be achieved by manpower at the beginning, a group of people pulling or using animal power.

Movable pulleys and gears can achieve the effect of adjusting power and direction, which is the physics knowledge that Guo Shao learned in middle school, and he can only rely on these things.

So he drew a very absurd picture on the paper, first scribbling a group of people pulling a long rope, and then the rope was a pulley...... This is followed by Add Ideas. Nowadays, only wood can be used to make gears, and even if the pitch can be calculated, the bearing capacity and wear of wood are a big problem. Guo Shao thought that it was easier to use pulleys, and the rope could also be replaced by iron chains, as long as it was thick enough, it could withstand the force.

After a while, the image of the engine moving back and forth came to his mind, and the realization of some kinetic energy conversion should be related to mechanical principles. He used to take the course of mechanical principles, but unfortunately he didn't take it seriously at the time, and now he basically returns it to the teacher.

If the "power system" can be like a grinding disc, Guo Shao imagined a scene in which a group of mules followed the grinding disc and grinded the surface; The rotational kinetic energy is then converted into a repeated linear motion of the hammer up and down through the device. That's where the value comes in.

What to do? Guo Shao touched the back of his head.

Second Sister Fu yawned and said, "I'm going to go to sleep first, and my husband shouldn't stay up too long." ”

Guo Shao nodded, pondered for a while, and couldn't figure out a clue. I haven't been in contact with these things for too long, and I think about ancient things all day long, and my mind is a little confused when I pick it up for a while. He simply put down the brush and walked to the bedroom, only to see that the second sister Fu was already asleep.

Guo Shao pressed the quilt on the bed, remembering that he hadn't been with Yulian and Yang for a long time...... As soon as she got home, she was followed by Fu Ermei, and no one else had the courage to fight with her. He immediately quietly went out of the bedroom, and when he saw that the light in Yuqing's room was still on, he walked to the door, opened the door and said, "Yuqing, get up and bolt the door of the hall, and I'll go to rest elsewhere tonight." ”

Yuqing pulled the quilt around his neck and tightened it, glaring at him. "What do I do not do to you, and stare at me?" Guo Shao didn't have a good breath, and when he saw that she was awake, he didn't stay long, so he turned around and went to the hall to pick up a lantern, and walked out of the gate and went straight from under the eaves to the east.
