lying down

In fact, compound bows already existed in ancient times, but they did not have the professionalism and high-tech of the previous life.The biggest feature of the compound bow of his era was the use of pulleys to achieve the effect of saving effort.The bow itself does not create energy.The bow just plays a role in transferring energy.When a compound bow is drawn, the limbs bend inward, which transfers the drawing force to the limbs, and the deformation of the limbs converts the kinetic energy of the draw into potential energy of the limb deformation.When the bowstring is released, the potential energy stored in the limbs is transferred to the arrow through the displacement of the bowstring, and converted into kinetic energy when the arrow flies.This is how the transfer of energy is done.So an important factor in choosing a bow is to see if the bow has "strength".In fact, it is the ability of the bow to store and release energy.

Ouyang Yu entrusted Seventh Brother with some tasks, such as finding some tendons that "the small ones are long and the big ones are round and moist".

However, he and Wulang rushed to the blacksmith shop in Zuoyun Town for several days to start building a large number of fine parts. Ouyang Yu made a list, and his scalp exploded when he saw it: one for the upper and lower bow arms, one for the bow body, aiming One device, one stabilizer bar,

One main string, one secondary string, one handle, two eccentric wheels, two bow arm bolts, and several other small rivets and parts.

This bunch of things, except for the main strings and auxiliary strings, basically have to be built by Goro himself. With the current manufacturing level, it can be imagined that this is a complicated small project.

On the first day, Goro built it more than a dozen times just for bowing. Either the specifications were too exaggerated, or the rigidity was not enough, or the size was wrong, and they were all scrapped.

On the second day, I finally built two qualified bow bodies, one for filling and one for spare. At the beginning of building the upper and lower bow arms, I forgot to unify the specifications and hurriedly reworked.

The third day.......

A few days later, when Qilang came to the town to ask them to go home for New Year's Day, both of them shook their heads and ignored Qilang. They just focused on measuring, building, and drawing again.The two of them only knew that Erlang had returned, but they didn't know anything else.They listened to the sound of New Year's firecrackers, and the two of them drank a pot of wine together. This time they slept for five hours, which was the longest time they slept recently.

During this period, the two had been eating in the restaurant in the "Juxin" blacksmith shop. During the Chinese New Year, everyone went home to celebrate the festival, and only the fourth senior brother who hadn't left brought food and water to the two of them.During this period, the two brothers will help whenever they are free.

Half a month later, on the Lantern Festival, when others went out to admire the lanterns and beauties, the two of them wept with joy for making a usable eccentric wheel. Ouyang Yu and Wu Lang seemed to be obsessed. Unconcious.

Wu Lang's master, Chu Yun, came and took a look, but his eyes sparkled, and he turned back to the valley without saying a word.

When Chu Xiang came, he dragged Wulang to dinner, but was rejected by Wulang on the excuse that he was already in the ring.

The second brother and the seventh brother are here, no matter how they are pulled back to rest, they will not go to rest, and still maintain this high level of spirit to build and fit again and again.

Both Ouyang Yu and Wu Lang have something in their hearts, and they both have resolute personalities, one is for forgetting, the other is for hope.Both put their hearts and souls into it.

On the last day of the first lunar month in 628, Goro's senior brother and everyone were surprised to find that the fire that had been burning for a month had gone out, and everything around them was cleaned up, as if nothing had happened here. Not in the "Juxin" blacksmith shop.

At this time, the two of them had the same heart shape, and their hair was like wormwood.His eyes were red and his face was dirty, and there was a foul smell on his body.

The two walked back home quietly, put all the things they built into the package, hugged them in their arms, and fell into a deep sleep.

Seeing the appearance of the two, the old lady and Yun Niang couldn't help crying.

Erlang showed admiration in his eyes, while Qilang was envious.

When the two woke up, it was already two and a half days later, the two of them woke up one after another as if they had made an appointment.

After waking up and looking at the eyes of the crowd, the first thing was not hungry or thirsty, but the same question: "Why is it so stinky?"

The family laughed in astonishment, which meant that they had returned to normal and that they were fine.

After a meal of chicken and dog jumping, the hot water was boiled with less hot water, and the rice porridge was cooked with rice porridge. After they took a bath, they went out and drank three or four bowls of porridge in a row, and fell asleep again.

Since making the bow, Ouyang Yu rarely dreamed, and slept very soundly this night.

Maybe it's because he slept hard the past two days, but this night Ouyang Yu woke up at Yinshichu, he lay on the bed and recalled the experience of the past month, he couldn't help laughing: "Two desperate people, two lunatics!" In addition to filling his chest with joy and a sense of accomplishment, in his heart, Goro's stupidity shocked him, an iron-blooded soldier, and he couldn't help feeling admiration for Goro. Cong, that kind of energy to work hard for the goal is not something that few people can have.

I couldn't fall asleep, so I got up.Lighted the oil lamp, laid out all the parts and the main part on the bed, silently recalled the appearance of the whole bow and the fitting process, and felt the cold iron parts joined together one by one.

The bow body is erected, the upper and lower bow arms are assembled and fixed, the grip is fixed, the upper and lower eccentric wheels are fixed, the main and auxiliary strings are wound, the sight is fixed...

Ouyang Yu assembled it patiently, sometimes the order of assembly was reversed, and he had to disassemble the whole thing and start over again.

When the bow was completed, Ouyang Yu gently held it in his hand, a feeling of metal touching his skin came from the grip, Ouyang Yu smiled in relief, got up dressed, and left with the bow.

"Xiao Lang, the meal is here, I added a lot of meat for you today, hehe, get up and eat." Yunniang knocked on the door while talking, and the door opened in response, but there was no one inside, "Where is anyone?" Mother put down the food plate in her hand, and checked under the bed and table, but there was no one there.This startled Yunniang: "Qilang, come quickly, the little brother is gone!"

"What, who is missing? Little brother?" Qilang and Goro said in unison.

"I brought food in just now. The room was unlocked. I searched all over, but I couldn't find my little brother! What should I do?" Yunniang's eyes turned red as she spoke, and a living person disappeared. How could she Can you be in no hurry.

"Don't worry, since the door was unlocked when you opened it, it should be fine. I think he has something to do when he goes out. But let's look for it first, just in case. Wulang, you go to the east of the village, Qilang, you to the west of the village, Yunniang, you and you Sister-in-law is going to the south of the village, and I’m going to the north of the village. Mother, please stay at home and let your two grandsons run errands for you. Let us know if you have any news. If you don’t find Ouyang Xiaolang in an hour, you should go back home first. Let's discuss again." Erlang is worthy of being a housekeeper for many years, he is not surprised when things happen, he directs well, and arranges everything.

Everyone was about to go out when an old man in the village passed by the door and said, "Wu Lang, you are so skillful, your hands are so skillful! You are indeed the apprentice of that old ghost, amazing, amazing!"

"What's so ingenious?" Goro wondered, the words were so nonsense that people didn't understand them.

"Hey, Wulang, why are you being so modest! Who in the village doesn't know that you made a bow, and you hold it very well! The little old man has something to go home, otherwise just watch it later." The old man said.
