Chapter 8. The scribbles on the ground? No, they're celestial script!
When Zhao Di ran back to the cave dwelling, her face was flushed red from the wind, but her eyes were bright and sparkling.
"Father! Father!"
Before she even stepped inside, the little girl started making a fuss.
"Grandpa next door is thirsty and wants some water!"
Lin Jianguo was trying to move his "iron leg" inside the house.
Hearing his daughter call out, he quickly pulled down his trouser leg to cover the strange-looking exoskeleton.
"Run slowly, don't fall."
Lin Jianguo caught Zhao Di as she lunged at him and brushed the snow off her body.
"The old man next door? You mean the new guy?"
Lin Jianguo frowned.
He had heard the village chief say that they were "bad elements" sent down from above for reformation.
At times like these, nobody wants to associate with such people, for fear of getting into trouble.
But looking into his daughter's anxious eyes, Lin Jianguo's heart softened again.
"Okay, Dad will go and bring him a bowl of water."
"He's a pitiful person too."
Lin Jianguo sighed.
He was a soldier, hard-hearted, but also couldn't bear to see the elderly, weak, sick, and disabled suffer.
Moreover, in this freezing weather, not even being able to get a sip of hot water is enough to freeze someone to death.
Lin Jianguo scooped up a large bowl of hot water, thought for a moment, and then sprinkled in a pinch of salt.
These days, salt is a precious commodity, but it can give you some strength.
"You stay at home, Dad will take it."
Lin Jianguo, holding a bowl, pushed open the door and went out.
Zhao Di followed behind like a little tail.
"Me too! Me too!"
Lin Jianguo didn't stop him, since it was right next door anyway.
Inside the cowshed, Chen Zhiyuan leaned against a pile of hay. The milk candy in his mouth had melted, but the sweetness still lingered in his heart.
Hearing footsteps, he struggled to lift his head.
A tall, burly man strode in, carrying a black pottery bowl.
Chen Zhiyuan's gaze froze instantly.
It wasn't because of that bowl of steaming water.
It was not because of the man's walking posture, but because of the way he walked.
As an expert who has studied mechanical dynamics his entire life, Chen Zhiyuan has a very keen eye.
When a normal person walks, the bending of the knees and the exertion of the ankles follow biomechanical principles.
If there is an injury, there will definitely be compensatory limping.
But this man in front of me...
Chen Zhiyuan saw it clearly.
Although the man's left leg looked somewhat stiff, each step he took was extremely steady, even carrying a certain...
A mechanical sense of precision?
The force feedback didn't feel like muscles and bones were supporting it; it felt more like some rigid structure was assisting in the transmission!
"Old comrade, have some water."
Lin Jianguo walked over and handed the bowl to him.
Chen Zhiyuan snapped out of his daze and quickly took the bowl with both hands.
The rough earthenware bowl burned his palms, yet it brought him immense comfort.
"Thank you... thank you..."
Chen Zhiyuan ignored the heat and drank it in big gulps.
The warm salt water flowed down his esophagus, soothing his nearly frozen internal organs.
After drinking the water, Chen Zhiyuan breathed a sigh of relief, feeling as if he had been given a second chance at life.
He looked up and gazed gratefully at Lin Jianguo.
"Brother, thank you for the water, and thank you for your child's candy..."
"sugar?"
Lin Jianguo paused for a moment, then looked down at Zhao Di, who was hiding behind him.
Zhao Di stuck out her tongue guiltily.
“It was given by the fairy uncle, and Zhaodi gave it to Grandpa to eat.”
Lin Jianguo's heart tightened.
This girl, why does she take everything out!
But in front of outsiders, he couldn't say anything and could only give an awkward smile.
"The child is just being immature, please don't take offense."
Chen Zhiyuan waved his hand, about to speak.
Suddenly, his gaze passed over Lin Jianguo's shoulder and landed on the courtyard outside the cave dwelling.
He was in such a hurry when he came in that he didn't notice.
Just now, the wind blew some of the loose snow in the yard away.
It revealed the solid, loess soil beneath.
On that yellow earth, black lines were crisscrossed.
That was the "graffiti" that Zhao Di drew yesterday with a fire poker.
Because it was frozen solid, and because it was covered by snow last night, it hasn't been trampled yet.
Chen Zhiyuan's pupils suddenly contracted.
What is that...?
At first glance, it looks like a child's scribbles.
But……
The curve of those lines...
The relative positions of those circles...
And those seemingly messy, but actually perfectly connected lines...
Chen Zhiyuan felt a "boom" in his mind, as if he had been struck by lightning.
Ignoring his weakness, he scrambled up from the haystack and stumbled out of the cowshed.
"Old comrade! What are you doing?!"
Lin Jianguo was startled, thinking the old man had gone mad, and quickly chased after him.
Chen Zhiyuan couldn't hear him at all.
Like a possessed madman, he collapsed onto the snow in the Lin family's courtyard.
Ignoring the cold ground, he frantically shoveled at the loose snow with his hands, which were covered in frostbite.
"Don't move! Don't move at all!"
Chen Zhiyuan shouted in a hoarse voice, his eyes fixed on the ground.
As the snow was cleared away.
The complete "graffiti" was displayed in front of him.
This is a complex mechanical structure diagram.
Although it was drawn with charcoal ash, the lines are rough, and some parts are even drawn crookedly.
But in the eyes of expert Chen Zhiyuan, it was simply a masterpiece!
No! It's ten thousand times more precious than a famous painting!
"This...this is a multi-link transmission structure?!"
"This is... an alternative to hydraulic damping? Utilizing the dead points of springs and levers to store energy?!"
"My God... the design of this joint... the stress angle of this bearing..."
Chen Zhiyuan's fingers trembled as he traced those lines in the air.
He kept spouting out strings of technical terms that Lin Jianguo couldn't understand.
The more Chen Zhiyuan looked, the more alarmed he became.
The more he looked, the more his scalp tingled.
When he was studying in the Soviet Union, he saw the concept drawings of the most advanced individual soldier exoskeletons there.
But that was too bulky, and you had to carry a huge battery pack, so it wasn't practical at all.
But this design...
Brilliant!
That's brilliant!
It completely abandons electric drive and uses only the human body's own gravity and leverage principle to achieve a multiplication of power!
This is simply a work of art that takes mechanics to its extreme!
Moreover, every detail on these drawings takes ergonomics into account, and even the stress of the materials has been calculated!
"Who drew this?!"
Chen Zhiyuan suddenly raised his head, and two balls of madness burned in his cloudy eyes.
He stared intently at Lin Jianguo, his voice trembling like a leaf in the wind.
"Who painted this?! Where is he?! I want to see him! I want to become his student!"
Lin Jianguo was frightened by the old man's appearance.
He subconsciously hid Zhao Di behind his back.
"What master? This is... this is just a kid's scribbles..."
Lin Jianguo felt uneasy.
Although he knew the blueprints were amazing, he didn't know they were so amazing in the eyes of experts.
"Scribbling?!"
Chen Zhiyuan seemed to have heard the biggest joke in the world.
He pointed to the exquisitely crafted knee joint on the ground and roared:
"You call this scribbling?!"
"Even if my mentor, a meritorious scientist of the Soviet Union, were to calculate the force at this one point, it would take him three days and three nights!"
"The mechanical principles contained within this are at least twenty years ahead of current textbooks!"
"This is an encyclopedic book! This is a true industrial encyclopedia!"
Chen Zhiyuan was so excited that he trembled all over, and his face was covered in tears and snot.
He lay on the ground, wishing he could kiss the soil.
"Tell me! Who drew this?!"
"Could there be a reclusive master living here?!"
Lin Jianguo's heart skipped a beat when he saw Chen Zhiyuan, who seemed to be going crazy.
broken.
This old man is an expert.
It can't be hidden anymore.
Just then.
Zhao Di, who was hiding behind Lin Jianguo, peeked out with her little head.
She looked at the old man lying on the ground eating dirt with an innocent and naive expression.
"Grandpa, are you looking at my painting?"
“Those are the iron pants that Zhao Di drew.”
"The fairy uncle said that if I draw this, my father's legs will stop hurting."
The air suddenly became quiet.
A deathly silence.
Only the cold wind whistled past, carrying snowflakes.
Chen Zhiyuan stiffly turned his neck and looked at the three-year-old child who was sniffling.
His mind went blank.
The CPU is completely burned out.
"What...what did you say?"
"You drew this?"
Chen Zhiyuan's voice was so soft, as if he was afraid of scaring something away.
"Mmm!"
Zhao Di nodded, and proudly puffed out her small chest.
"Zhao Di's drawing is so good, the fairy uncle even rewarded her with sweet water!"
Chen Zhiyuan looked at those tiny hands, no bigger than walnut kernels.
He then looked at the blueprints on the ground that were enough to shock the world.
An overwhelming sense of absurdity nearly made him faint.
Three years old?
illiteracy?
Did they draw mechanical blueprints that were ahead of their time?
Is this even scientifically possible?!
Is this even reasonable?!
But……
Chen Zhiyuan's gaze suddenly fell on Lin Jianguo's legs.
That strange walking posture just now...
That subtle sound of metal rubbing together...
An amazing idea exploded in his mind.
He lunged forward and yanked up Lin Jianguo's trouser leg.
"Old comrade! What are you doing!"
Lin Jianguo tried to dodge, but it was too late.
