The carriage did not arrive in the town until noon. Shen Xu's mental state had almost recovered. Apart from the occasional pain in his shoulder, he no longer felt any discomfort elsewhere.
The knife wound on his shoulder wasn't deep, but it would be a lie to say it didn't hurt. But in order not to upset Song Lin, Shen Xu had to endure the pain as much as possible, trying to look calm and composed.
Her physical condition is very good. She was drowsy due to fever at night, but after drinking two bowls of hot soup this morning, she became full of energy. Her voice is also much louder and no longer weak.
Song Lin immediately went to the town to get some medicine, including internal medicine, external application, and blood-tonifying medicine. Seeing that she wanted to take a shower, he worriedly stopped her, "Xiu Xiu, you still have a wound on your shoulder. The doctor said you can't get it wet. If it becomes festered, it will be troublesome."
"But I'm too sticky and smelly." Shen Xu sniffed himself and showed a disgusted expression, "If I keep covering it up, I'm afraid you'll vomit when you hug me. Besides, there's so much sweat around the wound, it's really going to fester."
Song Lin couldn't resist her insistence, so he had to agree to her request and warned her, "You must drink the medicine obediently."
After they had showered and changed into clean clothes, the two decided to rest in the inn for a night before setting off again since the Imperial City was so close.
After Xiao Mingcheng fell into their hands, Pei Zhiyuan became less cautious against Song Lin and his wife. When the two said they wanted to go shopping, Pei Zhiyuan only sent one person to follow them, as if to say, "If you want to run, just run away quickly."
Chen Xu went to the street to buy some wood, porcelain, lead blocks and other items. He bought a lot of various things and rudely ordered Ah Hu, the mirror user from the Xuanjing Division, who came with him.
Ah Hu did not particularly resist her orders. He took whatever was given to him and asked from time to time what these things were used for.
Shen Xu didn't pay much attention to it. After buying the things, he locked himself in the room and started studying those things.
But Ah Hu always found opportunities to talk to her and show his affection to her. Shen Xu did not let him sit idle and simply asked him to help cut wood.
As Ah Hu was whittling wood, he lowered his voice and asked, "Miss, have you really lost your memory?"
"Yeah." Shen Xu continued drawing without raising his head.
"Miss, are you really going to the capital to assassinate the Imperial Master?"
"Um."
"But it's hard to accomplish anything relying on people like you."
Shen Xu glanced at Ah Hu indifferently without answering. He picked up the wood he had cut, put it together and examined it, and said, "You have good skills. Can you cut another thirty of these?"
Ah Hu: “…”
She spread out the blueprints and asked him to help carve out the parts for the new weapon, while she took a piece of sandstone and began to polish the porcelain fragments.
At this time, Pei Zhiyuan walked in. He glanced at the large and small objects spread out on the table, then glanced at Ah Hu who was concentrating on carving wood, and picked up a polished arrow and looked at it.
"Are you going to make the arrowheads out of ceramic, or hollow?"
"Um."
"Ceramics are so hard that even ordinary iron armor can't penetrate them. How can we deal with the Imperial Master's breastplate?"
"This is the whistling arrow commonly used by northern armies on sentry duty. It makes a whistling sound as the arrow flies."
Pei Zhiyuan looked at Shen Xu with sharp eyes, raised his eyebrows and asked, "Do you still know about the wind-into-the-wind arrows of the Xue family army in the north?"
"This whistling arrow is not exclusive to the Xue family army. The Red Sand Tribe of the Beihai Kingdom and the Feiyan Army of the Yanyang Kingdom all have similar weapons to guide the way forward. It's just that ceramics will not be attracted by the stone mother." Shen Xu answered calmly, checking the wood cut by Ah Hu one by one, and picking up the knife from time to time to modify it.
Pei Zhiyuan flipped through the stack of drawings she had drawn with great interest. "Miss Shen really plans to shoot the Imperial Master with a crossbow. How do you plan to do it?"
Chen Xu didn't shy away from the topic. He directly unfolded a map of the Rock Imperial City's defenses in front of Ah Hu, pointed to the towering palace in the southwest corner of the city, and said, "This is Xuanhe Palace. According to Master Pei, the Imperial Preceptor bathes and rests here every afternoon. I plan to fire whistling arrows from the northeast corner while he's bathing to distract most of the guards. Then, I'll use this crossbow to snipe him from this sentry tower."
She spread out a drawing, which showed a very special crossbow. The crossbow looked several times smaller than an ordinary crossbow, but its structure was very complicated. It had no arms or tips, only a long arrow guide groove with four spiral springs on both sides. The bowstring was distributed in a circular shape in the arrow guide groove, and on the side was a winding wrench connected to a gear to control the tightening of the spring.
"Is this a crossbow?" Pei Zhiyuan frowned slightly. He couldn't understand it anyway. A crossbow usually has a crossbow arm connected to the string, but the drawing was bare and it really couldn't be seen as a crossbow.
"Well, I named it a spring crossbow and ditched the crossbow arm to make it narrower and easier to hide."
"The sentry tower is a full three hundred feet away from the Xuanhe Palace. Shooting from above would reach even further. The range of a good bow and arrow is only two hundred feet. Even if this crossbow is amazing, it definitely can't reach that far."
Shen Xu nodded and calculated, "The sentry tower is sixty feet high and three hundred feet away from the Xuanhe Hall. The distance from top to bottom is approximately three hundred and six feet. The crossbow's string rebounds thanks to a power spring, so the range should be longer and the power greater."
"Then how do we transport this crossbow and arrows to this watchtower?"
"Use the rock climbing machine of the Xiling Feiyan Army." Shen Xu thought for a while and pulled out another drawing from the stack of drawings. It was the rock climbing machine of the Xiling Army of Yanyang Kingdom.
Pei Zhiyuan stared at the drawings she provided in a daze, and said in amazement and surprise: "You still do this!"
This is the secret of Yanyang Kingdom. The reason why Jiangling's Yang Family Army can live in peace with Yanyang Kingdom's Xiling Feiyan Army is entirely because each of them has its own unique skills. The Xiling Army's skills of climbing walls and running on rooftops allow them to move freely in the mountains with layers of rocks, taking advantage of the geographical advantage.
It is said that the climbing mechanism and the canine claw arrow were both designed by Jiang Yu, the Minister of Works of Yanyang State. The climbing mechanism is fixed to the waist of the person, with two sets of steel ropes on each side to control balance and movement.
The structure of the mechanism is very complicated, consisting of a launching crossbow, a rope, a hook and a retraction device. The design of the hook is the prototype of the canine eagle claw arrow, which is shot into the rock wall.
By fixing any set of ropes, you can freely climb and swing between the mountains, achieving rapid movement on cliffs.
But now, the eldest daughter of the Xue family has cracked their secrets and revealed the structure of this equipment. If these equipment are equipped to the rebels, the Beiling Pass will no longer have any natural defenses, and the Haoyue Kingdom will truly be in a state of dynastic change.
Pei Zhiyuan secretly took a deep breath. This person must not be sent back to the north. If she regained her memory, she might not be able to be used by him, but would only be destroyed.
