Liu Ruyan was secretly surprised, and glanced from the drawings in front of him to the booklet "Examination of Work" placed next to it.
This craft work has detailed specifications for the shapes of chariots, carriages and weapons. The book uses "rules" and "moments" as the basic units for data calculations.
This set of calculations is a meticulous work, and there can be no mistakes.
On the other hand, Gong Shuyu was quick in thinking and was able to make a bed crossbow with ease even for the first time.
At this moment, he had calculated the curvatures of the three longbows and began to build them.
"Soldier, take ten silkworm cocoons and twist them into bow strings for me." He ordered without raising his head.
She did not dare to neglect in helping Gongshu Yu.
Liu Ruyan picked out ten large and plump silkworm cocoons from the basket, processed the cocoons, picked out the silk threads inside one by one, and twisted the strings.
Liu Ruyan handed the twisted bow string to Gong Shuyu for inspection.
Gongshu Yu took it and twisted it into the eye of the bow, tested its toughness, and praised: "Your skills are really exquisite."
At that time, the young man was sitting by the window, his face facing the misty dusk clouds outside the window. When he smiled and passed by, it was like the setting sun on the horizon, so bright and dazzling.
The system prompt sounded unexpectedly: "The plot character Gong Shuyu, the hatred value is -20."
So when Dong Qingxian went back to his tent to rest, he saw this scene.
Gongshuyu polished the crossbow with rigor and conscientiousness.
Liu Ruyan twists silk to make strings, and they cooperate with each other tacitly.
In just one day, these two people became strangely... harmonious?
Dong Qingxian rubbed his eyes to make sure he was not dazzled.
"You are..."
Liu Ruyan didn't even raise her head, and continued to peel off cocoons in her hands, "My little brother has recovered. He wants to make a bed crossbow as soon as possible."
"As long as you are fine." Dong Qingxian looked at the wood and parts that occupied most of the place. In the middle, the siege bed crossbow had begun to take shape.
Dong Qingxian rolled up the edges of his sleeves, eager to give it a try: "Why don't Qingxian come and help?"
Gong Shuyu took some time out of his busy schedule and glared at him. Apart from their brute strength, how could these mud-legged people do such a delicate job?
But when the words came to his lips, he turned out to be: "Brother, you should rest after a tiring day. How dare you bother me with such menial work?"
"It's not troublesome, it's not troublesome at all." Dong Qingxian took the drawing and put the square ruler on the wood to draw. With skillful movements, he used the ink fountain to draw a straight line and asked without raising his head, "Ayu,
Do you think it’s like this?”
Ayu?
Gong Shuyu's brows trembled.
Hey brother, do I know you very well? You can call me Ayu at will?
Dong Qingxian was completely immersed in the joy of carpentry. He picked up the saw gracefully and said with a gentle look on his face: "I built a wooden house in Shu."
Gongshuyu was quite surprised. He didn't expect that there were hidden dragons and crouching tigers in this camp. It was true that people were not as good as they appear.
Liu Ruyan was also surprised. She didn't know that Dong Qingxian, who was proficient in music, had such skills.
She smiled and asked: "Did you build the house on the mountain yourself?"
Dong Qingxian started sawing wood, "No, I built a dovecot."
Liu Ruyan sneered: "The pigeon house must be very ingenious..."
"Yan'er is so impressed." He said with a smile, holding a pen in his hand and swiping ink on the paper, drawing a square pigeonhouse with a round hole in the middle.
“I think it took several months to build the dovecote well, and I had to cut down two birch trees to build it.”
Liu Ruyan: "..."
Gong Shuyu: "..."
If it weren't for the seriousness of his expression, Liu Ruyan would definitely have thought he was joking.
Just two birches for a gadget like this?
I'm afraid what he built is not a pigeon house, but a pagoda that reaches the sky!
In an instant, a tall and majestic building appeared in her mind.
Until Dong Qingxian sawed the first piece of wood.
He said "Oh!" and stared at the broken wood with great regret.
Just now, some real energy was injected into it unknowingly, so that the board collapsed and irregular gaps appeared on the edges.
It seems there is no way to use it.
Dong Qingxian seems to have become accustomed to this.
He picked out suitable wood again, picked up the hacksaw, and started working.
This time, nothing went wrong from beginning to end, Liu Ruyan thought to herself.
But it turned out that she was still too naive.
Every piece of wood that passed through Gongshu Yu's hands was put to its best use. He cut it with a steel saw, quickly and steadily, smoothly and vertically, as smoothly as cutting tofu.
On the other hand, Dong Qingxian was probably used to playing the huqin. Once he got this hacksaw in his hand, he moved the bow, vibrated the strings, and the saw teeth moved up and down, whirling between the wooden boards.
The final sawed section looks like a dog chewing it and cannot be made into a mortise and tenon structure.
Dong Qingxian realized this and went to pick wood again.
The corner of Liu Ruyan's mouth twitched, if he continued like this, no matter how much material he had, it wouldn't be enough for him to waste!!
It seems that we have to find a way to divert his interest.
"Erhei -" she opened her mouth and called.
Dong Qingxian, who was pretending to be Zhang Erhei, subconsciously turned his face to listen to what she was going to say next.
"Yesterday, Doctor Gou dug out a honeycomb in the ravine and brought back a lot of osmanthus honey. He should have some left over there now. If he leaves late, he might finish it all..."
Dong Qingxian's eyes lit up when he heard the three words "osmanthus honey".
Then, before she finished speaking, Dong Qingxian turned around, picked up a clay pot, and rushed out in a hurry.
Gongshu Yu hadn't yet reacted: "Where did this kid go in such a hurry?"
"Where else can we go?" Liu Ruyan finished twisting the thread, "Just like you, I am thinking about that bit of honey."
As a Shu native, Dong Qingxian's paranoia about sweetness has reached the point of being insane and outrageous!
It is said that people in Shu like to eat sweet honey.
Dong Qingxian usually eats tofu and milk dipped in honey. He even dips gluten and meat in honey for seasoning.
This kind of eating custom is really unbearable for northerners!
So along the way south, whenever she saw a "Sichuan food restaurant", Liu Ruyan would gallop on her horse and try not to eat the sweet and delicious ancient Sichuan food in the restaurant.
Without Dong Qingxian holding him back, the speed of building the bed crossbow was much faster.
In mid-September, Gongshuyu finally built the first "three-bow crossbow".
When Xie Feng heard that the crossbow had been built, he asked the soldiers to push the crossbow to the rock to test it.
On the day of the trial, a group of people from the Song Army and Navy arrived at the back mountain early.
Dong Qingxian and Liu Ruyan, as personal soldiers, were naturally present.
This bed crossbow has a more sophisticated structure than previous crossbows. It uses the combined force of three longbows to fire arrows, and is equipped with pulleys on the track, which greatly saves the crossbowmen's energy, but is even more powerful than before.
In addition, there is a huge arrow placed in the arrow path in the middle of the bed crossbow, which is five inches thick. It flies out like a javelin and can be firmly nailed into the city wall.
Three slightly smaller arrows were placed on each of the left and right arrow paths, and seven arrows were fired in succession. All the fortresses hit were destroyed, and the towers and oars fell down.
The most amazing thing is that the bed crossbow can also fire treadle arrows. Several bed crossbows are fired at the same time. Rows of treadle arrows penetrate the city wall. The siege soldiers can climb up and over the city wall without using ladders. They can step on the arrow shafts.
.
As for the next step, it is to check the range of the bed crossbow.
Gongshuyu received the order, and he asked the soldiers to load the special giant arrows, while the other crossbowmen stood on the left and right, standing near the winch, ready for action.
Dong Qingxian looked at Qi Wei and moved forward a little closer. He looked at the rocks on the opposite side in the distance. He was at least 500 steps away from the bed.
But Gongshuyu was not satisfied, and he ordered again: "Go back another three hundred steps!"
