When he got closer, Jiang Shiyue found that the broken wall was bigger and heavier than he had expected.
"The wall is so heavy that I can't lift it." Jiang Shiyue said, throwing away the wood he was trying to use as a crowbar.
The man who called Jiang Shiyue did not refute, but was slightly disappointed.
This woman is fair and clean, and it's obvious that she's not cut out for work.
I was afraid that standing here would be in the way. Just as I was about to ask Jiang Shiyue to leave, I heard her speak.
"But I have a plan."
Everyone looked at Jiang Shiyue.
"It's very simple. First, we need some strong enough ropes or chains and then find a high place that can withstand twice the weight of this wall..." Jiang Shiyue briefly introduced the principle of leverage.
Most of those who tried their best to save people were ordinary local people. They had little education and had not received any professional training. They were skeptical about Jiang Shiyue's words.
"With so many of us, we can't lift it. Can we just use a few ropes to tie them around a longer distance?" Some people didn't believe it.
"Thank you for your advice, comrade. You can give it a try if you have nothing to do, but human lives are at stake and there's no time to waste. Let's go back and call for more help!"
"Who's got time to spare? Why don't we try her advice?"
“…”
After a brief discussion, everyone finally decided to give Jiang Shiyue's method a try.
Fortunately, there is no shortage of hemp rope in the disaster area.
Everyone found a few hemp ropes as thick as wrists and tied them to the top of the collapsed wall, then pulled them over from the nearby wall that had not collapsed, using this wall as a fulcrum.
The rescuers were divided into two groups.
One group stands behind a sturdy high wall and is responsible for pulling the rope.
Another group stayed where they were, to prevent Jiang Shiyue's unreliable idea from causing a secondary collapse to the injured.
Jiang Shiyue was responsible for standing aside to coordinate the two groups and shout slogans.
"One...two...three...up!"
The hemp rope quickly tightened as everyone pulled.
Finally, the collapsed wall moved, like a clam shell slowly opening.
The people who stayed where they were cheered in surprise: "It's moving! It's moving! Pull it up again!"
Several people couldn't help but run behind the wall to help.
When the medical staff saw that the gap was large enough to drag the injured person out, they immediately stepped forward.
One of the men, who looked like a doctor, examined the patient and said, "Quick, send him for debridement and see if the leg can be saved."
Before leaving, the doctor glanced at Jiang Shiyue with admiration in his eyes, "Comrade, if his leg can be saved, you are the biggest contributor. You bought him some time."
Jiang Shiyue: “…”
The few people who had just pulled the wall came over and their eyes changed from disdain to admiration when they looked at Jiang Shiyue.
"Little comrade, you're amazing! Before, so many of us couldn't lift the wall, but with two more ropes, we can do it."
"Comrade, you are an educated person, right? It's good to be educated. Send my child to school in the future."
“…”
Jiang Shiyue was distracted by the praises.
Shouldn't doctors also be educated people? Why did he seem to be hearing about the principle of leverage for the first time?
Later, during the break, Jiang Shiyue found the answer from Chen Shanhe.
Chen Shanhe said that not all doctors are trained in a professional field. Many of them are trained through family traditions, while others are self-taught.
During disaster relief, all available manpower is used, so whether or not one has a medical license is not so important.
As long as it can save people, that's enough.
But that happened later. At the moment, Jiang Shiyue used the principle of leverage to help others, and he was confident that he was not a useless person, so he went around to help others.
Jiang Shiyue helped out a few times, some of which were timely assistance, while others were not superfluous but were somewhat useless.
Having summed up his experience, Jiang Shiyue decided to play to his strengths and avoid his weaknesses, and instead of wasting time on physical work, he would do what he was good at.
The disaster area is without power, which is fine during the day, but rescue is the biggest challenge at night.
Aluminum flashlights also require batteries to illuminate.
Supplies are so scarce that batteries cannot be supplied in unlimited quantities for the time being.
In fact, the entire disaster area lacked everything within the golden 72 hours.
Often, various items for food, clothing, housing and transportation can only be delivered when the best time for rescue is coming to an end or has passed.
Jiang Shiyue borrowed a bicycle and rode to the place where the train collapsed. He dug out the two sacks of materials that Lu Zheng had found for him from the tilted carriage, tied them to the back seat of the bicycle, and rode back to the disaster area.
She poured the materials into the tent, which was a temporary resting tent for the pilots. They had all gone out for rescue, and at this moment only Jiang Shiyue and Yangyang, mother and son, were left, making the tent seem very spacious.
Jiang Shiyue tried to assemble solar panels and LED bulbs based on memory.
The first thing to do is the LED bulb.
LED lights are much brighter than tungsten lamps and are more suitable for outdoor use.
The core material of LED lights is the light-emitting diode. The basic structure is a semiconductor chip that emits light when powered.
The light-emitting diode is made of compounds such as phosphorus and nitrogen, and then the chip is fixed to the lamp panel with glue. The chip and circuit board are then connected, sealed with epoxy resin, and the outer shell is installed.
LEDs are much more shock-resistant than tungsten filament bulbs and are very suitable for rescue purposes.
However, making LED lamp beads requires a dust-free environment, which Jiang Shiyue obviously cannot meet.
Even the temporary operating tent cannot be guaranteed to be dust-free and sterile.
Use it for as long as you can.
Jiang Shiyue started assembling solar panels again.
Yangyang, who had been flipping through a book on Chinese medicine, could hardly pay attention to Jiang Shiyue when she dragged the sack into the tent.
Later, when he saw that Jiang Shiyue was tinkering with something strange, he put down the book in his hand and came over.
Jiang Shiyue has always believed in practical teaching. While doing hands-on practice, he explained to Yangyang the principles of LED lights and solar power generation.
After he finished, he handed the tool to Yangyang and asked him to try it out. "Come on, do you want to make one?"
Yangyang didn't answer and looked up at Jiang Shiyue.
Jiang Shiyue gave him an encouraging look with a smile on her lips, "It's okay to make mistakes. Of course, our Yangyang is so talented, he'll learn it after just one look, and he'll definitely do well!"
Only then did Yangyang take the materials from Jiang Shiyue and start trying them.
Soon, Jiang Shiyue's face became complicated.
In her previous life, she learned to do these things after practicing seriously several times under the guidance of professionals.
Now, Yangyang, a three-year-old child, only watched her assemble it once and listened to her explain it once, and soon he made a beautiful LED lamp bead.
Better than she did.
Jiang Shiyue felt proud but also somewhat uncomfortable.
It is said that all beings are equal.
However, the initial values are unevenly distributed.
The mother and son quickly installed a solar panel, a small wind turbine for wind power generation, and an LED lamp.
However, Jiang Shiyue encountered new troubles.
Whether it is solar panels or windmills, the purpose of their existence is to convert the collected solar and wind energy into electrical energy.
This process also requires batteries that can store electricity.
Jiang Shiyue was scratching her head when Chen Shanhe lifted the door curtain and came in.
He looked at the messy tent and raised his eyebrows in surprise. Then he looked down and saw a mother and son squatting in the middle of the mess, looking at each other.
