Craft a crossbow
The matter of casting pressure springs is more difficult than imagined, either the elasticity is not enough, or it is cheap to break, Yuancheng and Su Qi'er think day and night, constantly testing, mixing and refining steel, quenching and tempering, etc., after seven or eight times of trial casting, tossing for more than a month, in the end Lecheng cast ten usable pressure springs, and then in less than two days, the first spring crossbow was assembled into Lecheng.
In view of Yuancheng's concern that the range is not far enough, the spring is designed to be too thick, after installing the three springs, although the lever labor-saving mechanism is used, it is usually impossible for people to pull it, let alone fire continuously. So two kinds of them were assembled, one with only two springs and the other with three springs, and they were tested in a wide area outside the shipyard. Yuancheng personally served as a test shooter, and Su Qi'er, Feng Qingxue, Xuanyuan Po, Daojin, Ma Meng, Bailong and others were all present.
was planning the field, at this time Wang Ningzhi's carriage came over in a hurry, and not only Wang Ningzhi got off the car, but also his wife Xie Daoyun and aunt Xuanyuan Changqing. Everyone felt a little surprised, why did the Xie Daoyun sisters suddenly come here?
Wang Ningzhi said with a bitter face: "They insist on coming, and I can't do anything." ”
Xie Daoyun said: "We have been in the city for a long time, and we want to come out to breathe, but I heard that the Qingjiang Shipyard is quite supernatural, and I don't know if we are allowed to take a look." ”
Yuan Cheng said with a smile: "When the two fairy-like beauties arrive, even the evil ghosts of the Heavenly Name Falling Sun Mountain can't bear to scare you, haha." The two of them are here, it is really a bright wall, where is there no welcome!"
Everyone laughed, Xuanyuan Changqing glanced at Yuan Cheng deeply, his eyes were infinitely affectionate, but there was endless resentment and helplessness, and then he blushed and lowered his head. I haven't seen her for a while, but I have lost a lot, and my face is a little sickly and a little shriveled.
Yuan Cheng chuckled again in his heart, as if he had been stabbed, although Xuanyuan Changqing didn't say a word, but he once understood that he wanted to see him, and he was ashamed to answer, so he pulled his sister to come with him. Why is she so devoted to him, she should know very well that this is not possible!
Didn't Xuanyuan Changqing look at him unpleasantly before, when did he start to have a crush on him? Yuancheng suddenly understood again, he was also tempted by a certain classmate, but he was a beautiful person, and he didn't get too close to him, so he did something to make her angry, and occasionally had a few words with her. In fact, most of the people who are in love for the first time have this kind of resume, and they did it unconsciously, and it is hard to thank Yu Gao for seeing him once, and he is attached to him?
There are many facts that are not determined by people's wishes, and feelings are even more dependent, but the poor generation of golden branches and jade leaves has put an unbreakable constraint on herself.
Feng Qingxue already knew it, Xuanyuan Po and Xie Daoyun glanced at the two of them meaningfully, as if they could also see it, and there was a sad look in their eyes.
The matter of testing new weapons naturally can't be suppressed because of their coming, and in view of their extraordinary status, there is no need to avoid them, Yuancheng just can't say it to people who are not present today, even his parents and brothers. Next, please stand in the distance behind and start the test firing.
Yuan Cheng first tried two crossbows with pressure springs, aimed at the target of 100 paces, and with a "bang", he saw the shadow of the arrow flashing, and only one hole was left on the one-inch thick wooden plank, and sure enough, the wooden board was shot through! Everyone exclaimed. The second time he shot at the target of one hundred and fifty paces, and the bull's-eye hit the bull's-eye, and the arrow was trapped, and everyone exclaimed in surprise.
Yuan Cheng turned around and asked, "Su Qi'er, what do you think?"
"Very good! The two-stone bow used in the army has not yet shot 100 paces, and the standard crossbow has to shoot 120 paces. Besides, this crossbow can shoot ten in a row, which is already a first-class murder weapon, but I am afraid that the Zhuge God crossbow back then is also inferior. ”
The ancient "step" does not refer to a step, but to the left and right feet to take a step, there is a benchmark step to measure the length, "step" is longer than the contemporary one meter. One hundred and fifty steps was once close to two hundred and fifty meters, and it was hard to say that this spring crossbow was lethal within two hundred and fifty meters, and if it was fired from the back, it would be more than this distance at most.
Everyone celebrated, Yuancheng laughed, and the hard work was finally not in vain, and the lever was pulled again and again, and the remaining eight arrows were shot quickly, all of which hit the bull's-eye.
Then he picked up three crossbows with pressure springs and tried firing, and with a "bang", he pierced the target at 150 paces. Round into a re-pull, but the pull rod is bent and can no longer be used. The spring pressure is too great, and some accessories are too cowardly to stand up.
Su Qi'er said: "I can shoot one hundred and fifty steps away, and the power is once full, so I don't need to use three reeds." ”
Yuan Cheng thought about it, people like Ma Meng and Bai Long who are naturally strong, or who have practiced internal skills, can still shoot quickly with three springs, so he came up with a better purpose. "We re-modify the spring crossbow: one is called the two-reed repeater, which only makes two spring slots, which can reduce the size and weight one step further, for the same ordinary people's use; ”
Everyone gasped, one shot was three, thirty shots in a row, this lethality is too terrible!
Wang Ningzhi asked: "If you shoot three arrows at the same time, will the range become shorter?"
"Little impact on the range. The weight of the arrow is not heavy, and it is not much different from shooting three to shoot one, but each part should be re-created, and it is okay to do it a little harder. ”
Su Qi'er said, "If you cast some good arrows, I am afraid that the big shield will be shot through within a hundred steps." ”
Yuan Cheng said: "The arrow should also be reformed, the penetration should be strong, and at the same time, it should be in line with the continuous firing of the arrow magazine, and it must not be a matter of jamming the arrow, otherwise it will kill you when you are critical." ”
Su Qi'er said that these things on the bottom can be handled by him, the chief technician, and there is no need to bother with it.
Dao Jin was a little annoyed, "This instrument is too lethal, it is a murder weapon, I am afraid that it will hurt the heavens and peace." ”
Yuan Cheng said: "If you kill a person, you can gradually beat him to death with one punch, or you can kill him with one sword, and it is more kind to kill with a sword, so the instrument itself is not a murder weapon, and whether it is fierce or not depends on the person who uses it." There are only three three-reed crossbows, I use one, Ma Meng and Bailong each use one, and there are not many productions for the time being. ”
Ma Meng and Bai Long were so happy that they laughed, and when they heard that they only made three, they were also relieved.
Su Qi'er said: "The most difficult thing about this crossbow is the creation of the pressure spring, one is the difficulty of creating the mold, the second is the difficulty of finding the material, and the third is the difficulty of casting and quenching methods.
