There are two key factors that enable electric snowmobiles to travel on snow:
First, there needs to be sufficient snow pressure to prevent snowmobiles from pressing a large dent into the soft snow before they even start moving.
Secondly, a power assist system is needed to enable snowmobiles to move on snow. On hard surfaces, the friction between the car's rubber wheels and the ground, combined with the engine's driving force, can easily keep the round wheels moving with the vehicle. However, it is clear that on snow at least one meter deep, even the tallest wheels will struggle to sink into the snow and then move the vehicle.
Therefore, snowmobiles in northern countries often have their front two tires shaped like skis. This serves two purposes: first, to reduce the pressure of the snowmobile on the snow, allowing it to move more easily on the snow; and second, to use the skis instead of the car's two front wheels to turn the vehicle, preventing the snowmobile from being unable to turn around on the snow.
The snowmobile's "rear wheel" has been changed from a tire to a rotating mechanical rubber track. This increases the contact area between the snowmobile and the snow, and also provides forward power to the snowmobile through the transmission of the track.
This is the principle behind the manufacture and operation of snowmobiles.
However, even though there are two cars in the underground garage that Song Sanchuan can modify, neither Song Sanchuan nor Gou Fugui have the mechanical axles and metal rubber tracks that have been manufactured specifically for snowmobiles. Therefore, Song Sanchuan can only settle for a hybrid version of a "sled" and a "simple snowmobile" called a "mechanical sled".
"Both vehicles have inner tubes made of good shock-absorbing and impact-resistant soft rubber. Wang Xuan, the four of you should evenly apply a layer of soft rubber to the middle area of the roof I removed."
"I'll use the roof of the vehicle as the bottom of the mechanical sled. Now we need to make two small skids that can change direction in front of the bottom of the sled. Then you can use the tire rubber that has been heated to soften it to attach a layer to these two small skids to increase friction."
Wang Xuan and the other three nodded in agreement. After Song Sanchuan assigned the tasks, Wang Xuan assigned different tasks to his three friends. The four of them worked together in an orderly manner.
"Mr. Song, my wife and I can also help. Is there anything we can do?" Wen Boyuan asked, stepping forward as soon as he saw that Wang Xuan and his group had a task.
Song Sanchuan thought for a moment and said, "Then you guys should collect some cloth or fur from the hotel that can block the wind these next two days. When the car starts moving, the wind and snow will be very strong, and you might get a headache from the wind."
"Actually, it would be best to have some kind of ultra-lightweight yet sturdy carbon steel, that way you can make a streamlined windbreak with triangular corners facing forward. Unfortunately, it's hard to find and hard to make."
So our sleds don't have windows or anything, so we just have to wrap ourselves up as warmly as possible.
"I'll leave the specifics of how to better protect ourselves from the wind and snow to you two and Manager Zhou. Also, if possible, it would be best to collect some lightweight and easy-to-carry food, in case we can't resupply in the wilderness."
After hearing the task assignment, Wen Boyuan nodded seriously in agreement.
This was a somewhat challenging task, but the challenge made him feel at ease, giving him a sense of security that he was involved and wouldn't be abandoned.
So Wen Boyuan took his wife back to the sixth floor to find Zhou Ren, who was in charge of the overall situation there. Wen Xingxing went with her parents, but Wen Feilian stayed behind, wanting to contribute to the manufacture of mechanical sleds.
Looking at the bright-eyed boy, Song Sanchuan gave him a small toolbox: "Go and gather all the car lights I took apart together, and don't lose any related parts or wiring."
The eight-year-old boy took the small toolbox with the same seriousness as his father, then glanced subconsciously at the long-haired young man next to him, puffed out his little chest, and walked away.
So now only Gou Fugui, Xie Tianlang, and Si Wuyai are left watching Song Sanchuan make his move.
Si Wuyai had no interest in this kind of dirty and heavy physical machinery.
Seeing that Song Sanchuan wasn't in a hurry, he turned around and walked back: "Then I'll go back and continue preparing some antifreeze, snow melt, and related chemicals."
He refused to wear gloves and get covered in engine oil.
Song Sanchuan rolled his eyes at him: "Sometimes I even doubt if he's a real man."
Gou Fugui blinked: "Because he's too refined and looks a bit effeminate?"
"No, because he doesn't understand men's romance! Men's romance is cars and Transformers!!"
Xie Tianlang, who was capable of operating all kinds of mechanical vehicles, surprisingly nodded in agreement.
Gou Fugui, who only has a car driver's license: "..."
hehe.
He also said that a man's romance is wildlife photography.
"Now that we have the floor of the sled, and you're working on the mechanical skids for turning the sled, how are you going to get the power for the mechanical sled? There aren't any tracks here that can move on the snow."
Song Sanchuan chuckled: "We don't have complicated tracks, but we can make the simplest 'windmill-style' power wheel."
After Song Sanchuan finished speaking, Xie Tianlang raised his eyebrows, clearly understanding what he meant.
Seeing his Yuanyuan looking over with some confusion, Xie Tianlang smiled and made a waterwheel rolling motion with his hand.
"Have you ever seen a windmill? If you stretch and thin the blades of a windmill, you can let the blades directly penetrate the snow and touch the solid ground. Then, an engine is used to drive the windmill blades to rotate and generate mechanical thrust by contacting the ground. This gives the sleds that need to be pulled by external force automatic power."
"Although using this kind of thrust to move forward is not very smooth, and the faster the speed, the bumpier it becomes, this method can indeed automate the sled."
After thinking about how the windmill worked, Gou Fugui basically understood how to turn the "sled into a snowmobile".
But for some reason, he felt that the mechanical sleds he created would be a big challenge for the people riding them.
However, he now needs to find sturdy metal sheets or steel pipes from his own pockets to make "power blades".
Meanwhile, Xie Tianlang was standing nearby with welding tools, manually welding and reinforcing the mechanical blades.
"After the mechanical blades are welded, I will install two small, simple fan turbines at the rear of the vehicle, which will increase the aerodynamics somewhat."
Song Sanchuan had already envisioned what the "mechanical sled snowmobile" would look like, and for the rest of the morning and afternoon, they stayed in the underground parking garage and didn't go anywhere else.
The temperature in the underground garage was also very low, reaching -36℃, but fortunately, Gou Fugui pretended to find it from the hotel, but actually took it out of his own space and pulled out five iron barrels filled with wood blocks. He poured some gasoline on them and lit them, which served as five "heating stoves" around them.
In addition, everyone involved worked very seriously, even with some excitement and enthusiasm, and without realizing it, they all forgot about the cold and hunger.
However, they still didn't go hungry.
At lunchtime, Wen Boyuan's wife, Wu Dai, came downstairs with several insulated food containers to deliver meals to everyone.
The variety of food options for lunch was significantly less than that for breakfast, but at least the portions were large and filling.
However, by 6 p.m., when Song Sanchuan's modified mechanical sled snowmobile was basically complete, Wen Boyuan and his wife came down to deliver food, but behind them were more than a dozen people with unpleasant expressions.
"As you can see, we didn't sneak any food to eat more than our share. There are indeed some people down there who haven't eaten."
Wen Boyuan's brows and eyes were filled with anger, but his upbringing and rationality prevented him from uttering harsh words to these people.
The dozen or so people who came down with Wen Boyuan and his wife, along with Zhou Ren, showed surprise and expressions of "Are these people out of their minds?" when they saw that there were actually people in the cold underground parking garage.
However, when one of the arrogant young men, who looked to be in his late twenties, saw the modified snowmobile parked in the basement, he paused for a moment, then his entire face showed an expression of disbelief:
"Look what I see?!"
"The base of this vehicle is a roof panel, there are two crudely modified sleds in the front, and there are even two pieced-together metal windmills in the back?! Good heavens, don't tell me you're making snowmobiles?!"
"You guys don't actually want to drive this kind of crudely made vehicle, which probably can't even move, in the freezing cold outside, do you?!"
"Are you all out of your minds? Not to mention that this thing is definitely going to be a failure, with such strong winds and thick snow outside, how could you still want to go out?"
Gou Fugui and Song Sanchuan immediately showed their disgust the moment this arrogant second-generation rich kid opened his mouth.
As he spoke more and more, Song Sanchuan clenched his fists tighter and tighter.
If Song Sanchuan hadn't known that with his current strength, even a restrained punch could give this guy a concussion, he would have wanted to send him flying.
However, not being able to use your hands doesn't mean you can't use your mouth.
Although the wealthy and beautiful woman no longer has the bloodline of the talkative husky, who doesn't know how to talk back?
"So it's none of your business?"
Gou Fugui looked at him with his chin lowered to the side.
The arrogant young master who was mocking her suddenly stopped laughing: "You did something funny and you don't want us to laugh? What's it to you if I laugh?"
The wealthy beauty immediately gave him a genuine look of disgust: "Then go laugh somewhere else, you're making me cringe."
The arrogant young master couldn't laugh this time. He was about to curse Zu'an on the spot, but as soon as he opened his mouth, a snowball was accurately smashed into his mouth. But that wasn't the reason he was so terrified that he couldn't speak.
What terrified him most was that he hadn't even seen who had thrown a clump of snow into his mouth!
The arrogant young master kept spitting snow out of the car, and only then did the others take their eyes off the strangely modified vehicle.
However, the expressions on everyone's faces carried a hint of contemplation and a subtle, dark light that made Gou Fugui want to sneer.
At this moment, a kind-looking middle-aged woman stepped forward with a smile to ease the tension:
"Oh dear, young people shouldn't be so hot-tempered. It's fate that we're all staying in the same hotel to take refuge together."
"Young man, did you modify this vehicle? It looks quite interesting. Is this vehicle really capable of running on snow? This lady doesn't know anything about cars or mechanics; this is the first time she's ever seen a vehicle that can run on snow."
The kind-looking woman spoke while glancing at Song Sanchuan, her eyes revealing a clear look of anticipation.
"If this car can really run on snow, young man, you have to take your aunt for a spin and let her broaden her horizons."
Song Sanchuan gave the kind-looking old lady a formulaic, fake smile: "That might not work. I need to test drive the car after it's finished. The test drive might be dangerous and very bumpy, so I can't let you suffer like that."
"It's okay, it's okay! After you've finished your test drive, can I sit in the car for a bit?"
"That won't work either. If there are no problems after the test drive, we'll leave here by car."
Song Sanchuan was still smiling, but his refusal was decisive.
The older woman's expression darkened after being rejected twice. She frowned, about to lecture him: "Young man, that's rather rude of you."
Then she was interrupted by another middle-aged man with a large belly next to her.
"Are you really going to leave? Even if you can drive this car away, where can you go? Just like Xiao Zhang said, it's windy and snowy outside, and the temperature is already below minus fifty degrees Celsius. Aren't you just asking for death if you go out now?"
“What you’re doing is pointless. Instead of wasting your time here, you’d be better off going up to the sixth floor with everyone else to conserve your energy and wait for rescue. We’re doing this for your lives…”
Gou Fugui was really annoyed by these people's constant lecturing and self-righteousness.
He immediately called out, "Ah Lang!"
Then he shouted at the people opposite him, "What's it to you!"
"Did you hear me? This is none of your business!"
Then, Xie Tianlang bent a steel bar right in front of them.
The bent steel bar speaks volumes through its silence.
Even the most powerful middle-aged man kept quiet out of the blue.
They finally realized that this car modification was none of their business.
But they still refused to leave. At this moment, a pretty girl in the crowd spoke up in a soft voice: "Well, young man, may I ask where you are planning to go?"
“It’s freezing cold outside. We didn’t mean any harm; we were just concerned about you.”
Gou Fugui felt that anyone could have this kind of concern, and what he needed was peace and quiet.
However, seeing that these people were unwilling to leave even after being intimidated by his wolf-like weapon, he took the lunchbox and told them his destination to avoid them pestering him.
"Equatorial region".
When those three words appeared, the dozen or so people who came down with Wen Boyuan all showed expressions of shock and delight.
"You're actually going to the equatorial region?"
"Yes, yes, that's exactly where they can go! Right now, it's snowing all over the Northern Hemisphere and Antarctica is starting to freeze over. The warmest place on Earth is the equatorial region! Once they get to the equator, they can live a normal life!"
"Even if the equator is affected, the temperature certainly won't be as low as here. Maybe it won't even snow there! It'll feel like a crisp autumn day!"
A dozen or so people chattered for a few minutes, then suddenly fell silent.
They turned to look at the only modified car in the middle of the underground parking lot that could travel on snow. Without asking or probing, they knew there was no way they could get into that car.
The excitement we had just felt during the discussion vanished completely.
At the same time, negative emotions such as jealousy and dissatisfaction quickly and darkly sprouted in the hearts of these people.
Unable to get a car, they could only wait here, unable to travel to the safer equator. But the dozen or so people in front of them were different; they had a car, which represented another, longer-term, and safer possibility.
They are different.
This difference is something that is difficult for people to accept easily.
The atmosphere suddenly fell into an uncomfortable silence.
Little Wen Feilian even secretly reached out and grabbed Gou Fugui's clothes.
He disliked the way the adults looked at them silently.
After a while, someone spoke up: "Oh, have you guys already finished modifying the car? Didn't you guys say you were going to test drive it? Can I watch you test drive it from the side?"
The one speaking was that beautiful, seemingly delicate and fragile girl.
Song Sanchuan couldn't help but shudder and turned to look at Gou Fugui.
The car has indeed been modified, but should we test drive it in front of these people?
After all, these people can't hide their emotions anymore. If he finishes his test drive with such flair, won't their eyes be bloodshot with envy?
The long-haired youth chuckled softly as he looked at the expressions of the people opposite him.
"Let's give it a try."
What should you do when you discover that someone is being malicious towards you?
Avoid? Back down?
All of these are incorrect answers.
Once malice takes hold, it is impossible to avoid or back down.
At this point, you should slap them and kill those malicious people outright. If you can't kill them, you should at least instill fear in them.
Xie Tianlang smiled with great pleasure.
Song Sanchuan chuckled twice.
Do you really think they are virtuous people who do good deeds?
When facing the enemy, they can be as ruthless as the autumn wind sweeping away fallen leaves!
"Let's go, let's go give it a try! The entrance to the underground parking garage is blocked by snow. If you all want to see the test drive, then don't just stand around, come with us and shovel the snow to clear the underground passage! Then we can test drive the car, right?"
As Song Sanchuan spoke, he looked at Zhou Ren and said, "Old Zhou, why don't you go upstairs and ask the waiter to bring down some snow-clearing tools?"
Zhou Ren paused for a moment, looked at Gou Fugui and Xie Tianlang, and then actually turned around and went to the lobby on the first floor to find tools.
At this moment, Gou Fugui tapped his fingers and said with a smile to the four college students:
"Wang Xuan, go to the conference room on the sixth floor and call someone. Tell them we're going to test drive the snowmobiles. If anyone is interested and wants to see the test drive, they can come down."
Since these dozen or so people will definitely tell the people gathered in the conference hall on the sixth floor about the snowmobile anyway, it's better to notify them all at once so that everyone can see and understand clearly.
With more people, there will be more people with good intentions, bad intentions, or their own ideas.
Hearing Gou Fugui's words, the expressions of the dozen or so people who came down looked rather unpleasant. But they had no right to stop Wang Xuan and the others from calling for reinforcements.
Ten minutes later, Zhou Ren returned with a dozen waiters carrying dozens of shovels, brooms, and dustpans. At the same time, Wang Xuan and her three companions brought down more than three hundred people who wanted to see the snowmobiles.
Everyone crowded into the underground parking garage, but with so many people, the snow run was cleared much faster. Although many people were reluctant to shovel snow, with everyone supervising and teasing each other, everyone did their part.
Around 7 o'clock, the ski slope leading from the underground parking garage to the outside opened.
The hotel guests, who hadn't left the hotel for two days after the main entrance was closed, finally stepped outside again, braving the biting wind and blizzard, and truly came into contact with the world.
"Achoo! Achoo! Ugh, it's so cold! What's the temperature outside?!"
"I estimate it must be below minus fifty degrees Celsius. Hiss... Whew... This snow layer must be a meter or two deep! My God, with snow this thick, can that modified car really drive on it?"
"Oh no, I can't take it anymore! How are they even going to test drive the car? Forget about testing it, how are they even going to get it out of the basement and onto the snow? That's a problem!"
"Pshaw, that's why I said they're joking! They're out of their minds! That wrecked car couldn't possibly drive on snow! And you guys actually believe it?"
"That's not quite how it works. Look at how serious those young men are, it seems like they can do it. But now they should face reality, right? In this weather and on this ground, there's no way they can make it."
"Yes, it's impossible for us to leave."
So in the end, these people will still have to stay here just like them.
Therefore, they should have stayed here obediently, just like them.
However, as everyone was discussing it, they suddenly saw a car that shouldn't have appeared in their imagination.
They stared wide-eyed as the modified vehicle quickly "drove up" from the snow in the underground parking garage right before their eyes. The round-faced young man sat in the vehicle, his face full of excitement, while the two ridiculous, retractable, extendable metal windmill blades wrapped in cloth behind the snowmobile rolled merrily upwards.
Clearly, the car has passed the first hurdle: getting from the underground garage to the snowy terrain.
Even if we could drive up, what then? The snow is over a meter deep right now!
How is this car supposed to "jump" onto the snow?
Everyone watched in silence.
Many people are waiting for its failure.
However, they soon saw the tall, savage man and the handsome young man with long hair walk to the front and back of the car, respectively, and at the same time, they lifted and threw the car upwards with force!
They threw the mechanical snowmobile onto the snow.
Then, the people standing at the garage entrance, below the snow, saw the simple, rough, and aesthetically unappealing patchwork car draw a beautiful yet wild arc on the snow.
The curve is like the smiling face of a hard-working person, or, conversely, the downturned corners of a malicious person's mouth.
