The bonfire crackled, and the firelight illuminated three faces. Bana used a blackened wooden stick to keep stirring in the fire to make the flames burn bigger and brighter. Evelyn was still staring at the drawing to study the refraction angle of light, his eyes full of obsession.
Suleiman looks at Evelyn's obsession, promising, and he likes capable people.
"Bana." Suleiman turned to look at Bana, breaking the silence.
"Here, Master Suleiman." Bana, who had been hunkering down at the fire, immediately put down the stick and straightened his back.
Suleiman asked, "How often should the ropes be replaced on the construction site?"
Bana was stunned for a moment and quickly replied, "Sir, those are high-quality hemp ropes. They are very strong and can be used for a year and a half without any problem."
"Starting from tomorrow, replace it every few days and repair it." Suleiman's tone left no room for negotiation. "Use the rope that cannot be repaired to bundle materials. New ones must be used. I don't want to hear someone falling from the sky."
"If you can't use it, don't use it. It's only used to transport building materials and stones."
Suleiman knows that a businessman's character is to do big things with a small cost, so we must explain specifically that steel cable zip lines are prone to accidents, not to mention simple zip lines, which can be broken into pieces if not done properly. It is definitely not worth replacing an adult citizen with a rope.
"Yes, yes, I have written it down, Master Suleiman." Bana responded repeatedly, with a little cold sweat breaking out on his forehead. He did not expect that Suleiman valued the lives of its citizens so much.
Su Lai ignored him and turned to Evelyn who looked up at him and smiled. She seemed to be curious about the zipline. "What are you thinking about?"
Evelyn looked straight at Suleiman, the firelight flickering in her beautiful blue eyes. "Actually, I understand the principle of the zipline, but I am wondering why the things hanging on the rope can slide so fast."
"It was neither pulled by horses nor propelled by human power."
Suleiman opened his eyes Spectacles, women have a future, when will they sit under an apple tree and be hit by an apple?
He picked up a stone, weighed it in his hand, and raised his hand to shoulder height. "Look, I raised it here."
"It itself contains a downward force. The higher I stand, the greater this force becomes."
"Have you ever thought about why if I drop a stone from a high place, the destructive power is different from a stone dropped from a low place?"
Suleiman let go of his hand and the stone fell to the ground.
"The zipline makes use of this power. The starting point is set at a high place and the end point is set at a low place. It is like a slope. The stone is hung on the rope and will run down by itself. As for how fast it runs, it depends on the rope."
Suleiman pointed to the hemp rope, winch and wheels currently owned, and used the winch and wheels to straighten the rope and raise it.
Create such an environment.
"The rougher the rope, the slower it will run. If you change it to a smooth iron rope, the speed will be faster than you can imagine."
Evelyn's breathing stopped and he murmured to himself, "Yes, why, there is a difference in destructive power between stones dropped from a high place and stones dropped from a low place."
"Why the smoother it is, the faster it is, and the rougher it is, the slower it is."
"Cough! Cough! Cough!" Suleiman looked at her gradually falling into madness, coughed three times, don't go crazy, you are still of great use.
Suleiman interrupted Evelyn's thinking and pointed at the stars above his head, "Light follows a similar principle."
"Light likes to walk in a straight line, but when it encounters certain things, it also changes direction."
"Look!"
Suleiman took Bana the Beggar's kettle, and then snatched the wooden stick and rice bowl from Bana's hand. Ignoring Bana's resentful eyes, he poured the water into the bowl, and then inserted the blackened wooden stick into it.
Evelyn leaned forward, cheek to cheek with Suleiman, Spectacles opened his eyes wide, and the wooden stick in the water seemed to be broken from the water surface, showing a weird angle.
"It's bent...
."Evelyn whispered, his eyes filled with disbelief.
Suleiman asked her about her body scent. He remained calm and took out a crystal from House Terry's treasure house:
"It's not that the stick is bent, it's that the way you look at it is bent by the water."
"Water can bend light, and pure crystal can also do it. Evelyn, you have been drawing pictures for a long time, using your eyes under the night and candlelight,
Will seeing things be blurry?"
Evelyn rubbed her eyes subconsciously, an action she had done more and more frequently recently.
Drawing drawings as fine as millimeters under dim candlelight for a long time was a huge drain on her vision.
"Yes, when I was a child I could see the trees in the distance clearly, but now the trees in the distance turn into a blur of shadows in my eyes." She answered honestly, leaning against Suleiman.
Suleiman raised the piece of crystal to Evelyn, who was face to face, and stared into her eyes through the most transparent area:
"If we could polish the crystal into a specific arc, it would be like an invisible slope, allowing the light entering the eye to turn in advance..."
"Is it possible that those who cannot see clearly can see the world clearly again...::
Evelyn The whole person froze. If such a thing really existed, its value would be immeasurable. Countless scholars, nobles and kings would rush for such a thing.
Let human eyes pay attention to things, she didn't dare to think how crazy Citadel's students would be.
"Can this really be done?" Evelyn's voice was dry.
"Why is it impossible?" Suleiman took her hand and gently put the crystal into her hand. The cold touch of the stone made her shiver, and she lowered her head and looked at the crystal.
Suleiman held her hand and looked at Evelyn who lowered his head. "I only have this piece of decent crystal in my hand. It is the most valuable thing in the territory besides me."
"I'll give it to you."
"Because I believe you."
Seeing that the situation was not good, Bana ran away without even saying hello. Unexpectedly, Mr. Suleiman liked this kind of tone, so he had to share the news with Lushen and Roslyn. The two of them were recruiting beautiful village women everywhere. They had to change them to ugly ones to prevent the horses from being photographed on the horse's butt.
Evelyn was holding the small piece of crystal, which felt like she was holding the weight of a mountain. Her body was shaking constantly. She looked up at Suleiman, her blue eyes sparkling.
Suleiman coughed twice and looked away.
In the deepest part of the "Lion's Den" fortress, in a newly dug independent cave isolated from any passage, Evelyn began her work.
There is no day or night, only eternal candlelight,
The cave echoed with the sound of sand and stone rubbing against crystal. I don't know why the woman was so persistent and worked hard, polishing and polishing the finest sandstone, leather, and even the corners of her clothes over and over again.
Everyone was shocked and ignored any advice to take a rest. Only Suleiman ordered her to rest, so she took a short rest and continued polishing.
It failed countless times. The crystal piece was covered with scratches or the curvature was wrong, and the scene was distorted like a painting by a madman.
Finally, at a moment when she was in the cave, she didn't know whether it was early morning or late at night, when she raised two thin crystal pieces embedded in a simple wooden frame to her eyes.
The world became clearer than ever before. Every subtle texture of the rocks on the cave wall and the flickering light of the candlelight in the distance were all so clear that she shed tears.
When she handed the simple Spectacles to Suleiman with both hands, she suddenly fell towards Suleiman, was caught by him steadily, and fell asleep.
