"What's that sound?"
In the dense forest, an old man carrying a bamboo cage looked around in confusion. However, the thick forest in this mountainous area blocked all his views. After looking around for a long time, he still couldn't find anything.
The old man calculated his harvest for today. Looking at the gradually darkening sky, he shook his head helplessly and slowly walked down the mountain.
Not long after the old man left, a tall figure with a light blue body crawled out from the nearby thicket.
He tried to look up at the sky, but the huge head on his body was fixed to the armor and couldn't turn flexibly.
Only inside the huge head-mounted computing module was there still some space for his head to move. In the helmet, at an upward angle of 30 degrees from his line of sight, a display screen was showing the image of the sky.
It was the light sensing system mounted on the armor, showing the real-time images transmitted by the cameras all over his body.
After a while, a huge four-winged aircraft with a sky blue paint job, nearly ten meters in diameter, slowly descended from the sky and hovered 50 meters above Song Han, releasing two thin hoisting cables.
Song Han raised his hand and looked at the same sky blue paint coating on his arm, and asked with little confidence, "System, are you sure this paint can really block electromagnetic radiation?
It's not easy to make this aircraft. I hope it won't be shot down by a missile from the country."
The system explained, "The stealth coating can absorb electromagnetic waves, convert them into heat energy, and then dissipate the heat as the air flows. It doesn't block electromagnetic radiation.
Today, we need to test the short-distance ground-to-air movement system of the fully enclosed exoskeleton armor. According to calculations, as long as the air movement speed is less than 300 km per hour, this electromagnetic heat conversion coating is sufficient to shield most ground radar detections."
"What if it exceeds 300 km per hour?"
"If the aircraft flies too fast, the heat generated by the friction between the fuselage and the air will accumulate. In this case, absorbing electromagnetic radiation will further increase the thermal radiation of the aircraft. Even without the interference of electromagnetic wave radar, it will be monitored by thermal radiation radar."
Song Han fixed the hoisting cables dropped by the rotorcraft to the connection points on the armor and took a deep breath. "This kind of finished paint directly purchased from an external paint factory, which I didn't make myself, always gives people a feeling of unreliability. By the way, the cables you bought won't break, right?
My current exoskeleton armor and the electromagnetic pack weigh nearly a ton!"
The system's reply was still calm. "It's much stronger than you think."
"Target, Channel A3, flight altitude 300 meters, starting speed 200 km for constant speed cruising!"
As the words fell, Song Han's figure soared into the sky under the hoisting of the rotorcraft!
"Whoohoo! Take off!"
...
"Is this the place?"
In the remote mountain forest, at the end of a section of paved asphalt road, a somewhat dilapidated gate embedded in the mountain body came into view.
Parking the car in the overgrown empty parking lot in front of the gate, two figures, one big and one small, came to the mountain gate.
"Wei Mi Science and Technology Museum?"
Above the thick iron gate, the glowing characters showed a kind of abandoned dilapidation in the unmaintained mountain area.
"How do we get in? Are you sure it's still in business?"
The little girl beside him blinked and said, "I heard from the sister next door that it's still open. Her mother still works there."
Fang Jie turned his head and looked at the small compartment embedded in the mountain beside him and saw the sign of the ticket window. However, there was no one inside, and only something like an ATM machine was still glowing faintly.
Fang Jie was a bit stunned looking at the bare display screen at the ticket window.
"There are no buttons? How do you operate it?"
"Press this!"
The little girl beside him stood on tiptoe and reached out to click on the "Buy Tickets" option on the screen.
"A thousand yuan is so expensive!"
Fang Jie looked down at his sister's big round eyes and suddenly regretted his hasty decision today.
Flipping through the ticket purchase instructions and not finding any clause for children's free tickets, Fang Jie's regret grew even stronger.
"Brother, didn't you say that the Transformer model costs several thousand yuan to buy outside?
You can make one yourself later in there!"
"I just made a price judgment based on the fine processing details of that model. Who would be willing to spend several thousand yuan to buy it?"
In front of the ticket window, the two of them stared at each other. When he saw the mist forming in his sister's big round eyes, Fang Jie gave in.
Enduring the pain in his heart, he put his one-month salary into the money deposit slot and got two wristbands. Watching the gap where the gate beside them slowly opened, it was too late to regret now.
"With a ticket price of a thousand yuan per person, it would be a miracle if you don't go out of business!"
After swiping the card and getting on the small tram behind the gate, as the tram kept moving deeper, even though the bright LED lights on the ceiling illuminated the empty and deserted cave, Fang Jie's heart was still filled with tension due to his fear of large objects in deep caves.
"Younger sister, is this science and technology museum a legitimate one"
"Of course it is. Our school organized a visit here for us last year, and then I asked my dad to bring me here again. There are a lot of fun rocking cars inside!"
Upon hearing this, Fang Jie said in surprise, "Dad was willing to bring you here even with a ticket price of a thousand yuan?"
The little girl thought for a while and said, "I remember it was five hundred yuan last year. I pestered my dad for a long time before he agreed to bring me."
In the central hall of the science and technology museum, Song Han looked unhappily at the two figures getting off the tram. Anyone would be unhappy if their train of thought while working with great enthusiasm was interrupted.
However, currently, besides an aunt who helped him cook and do housework, he was the only one in the museum, and there was no one else to receive visitors except him.
The figures in front of the service desk did ease Fang Jie's nervous mood a bit. He led his sister forward and asked, "How do we play in this science and technology museum? Is there a tour guide?"
Song Han said irritably, "I'm the tour guide."
"What about meals?"
"There's a cafeteria at the back. There's an aunt who cooks. Just tell her what you want to eat, but you need to pay extra!"
Thinking of the ticket price at the gate that made him hope the science and technology museum would go out of business, Fang Jie quickly waved his hand and said, "No, no. We brought our own food. Just tell us where there's hot water."
Song Han looked at the instant noodles and snacks Fang Jie was holding and waved his hand indifferently. "Forget it. I'm the only one in the museum now. Let's eat together during the meal time."
"Brother, come quickly!"
Worried about his sister's safety, Fang Jie quickly ran over.
"Brother, lift me up! I want to ride the rocking car!"
Fang Jie looked at the more than one-meter-high, finely crafted Stegosaurus steel model in front of him and quickly waved his hand. "You can't ride this model. I can't afford to pay for it if it gets broken."
As the words fell, Song Han beside him activated a tall Tyrannosaurus Rex model. With the powerful strides of the Tyrannosaurus Rex's thick four legs, it walked over majestically.
"The models in the hall are all means of transportation in the museum. Just swipe your card after getting on. Without a means of transportation, you won't be able to see the whole venue in a day."
Watching the steady steps of the Tyrannosaurus Rex that Song Han was riding, Fang Jie's eyes almost popped out.
After lifting his sister onto the model, he quickly found one and sat on it with great interest.
Riding and driving the model was much simpler and safer than he had imagined. On both sides of the model's belly, there were two deep recessed grooves. After putting his legs in, the airbags would firmly fix his lower limbs.
There were two small handles on the model's neck. Just turning them could control the model's steering, forward movement, which was no different from riding a motorcycle.
Following behind Song Han's tall figure, Fang Jie stared intently at the steady steps of the tall model as it moved, and a series of questions popped up in his mind one after another.
"Is this really a rocking car?"
Song Han led the two figures, one big and one small, and casually entered a passage.
"Now we're going to visit the demonstration scene of future mineral mining. Remember to drive on the left and don't disrupt the operation of the motorcade."
Fang Jie carefully observed the figures that ran quickly from time to time in the passage. They were all in a similar shape to the dinosaur model he was riding, but more streamlined, just like huge mechanical dogs. On their backs were cartons about one cubic meter in size, filled with broken stones.
"Your venue doesn't have many visitors, but you still keep it running all the time?"
"Aren't you people?"
Song Han's words left Fang Jie speechless for a long time.
After the group rode the dinosaurs for nearly half an hour, they finally reached the hall marked as the raw material warehouse.
In the vast area of several thousand square meters, it was piled with stones. Several mechanical dogs, also in the shape of mechanical dogs, were using their buckets to dig the broken stones and pour them into the empty cartons of the mechanical dog carts beside them. Everything was in good order.
"It seems something is wrong?"
"What's wrong?"
Fang Jie thought for a long time before saying, "Why are they all four-legged? Aren't wheels more convenient?"
Song Han chuckled and said, "I've already said that this is a demonstration of future mineral mining. Who told you this is a demonstration of mining on Earth?
What if it's mining on Mars?
You can't build a road on Mars before mining, can you? Compared with the Earth's environment, multi-legged mechanical forms of movement are more adaptable to various terrains and are not restricted by the site.
Even on a 90-degree cliff, as long as you add a few more legs to the mechanical dog and simulate the forms of insects or horses, they can still operate on their own."
After a cursory tour, Song Han led them towards the smelting plant.
"Now we're visiting the future mineral raw material production workshop. The transported mineral raw stones will be crushed by a crusher and ground into micron-sized particles, and then decomposed by an ultrasonic oscillation furnace to produce raw material rods with a grade of 99%."
The little girl beside him looked curiously at the workshop behind the glass wall, which was fully operated by mechanical dogs, and asked, "Big brother, big brother, weren't you moving stones inside before? Why did you come out?"
"I got promoted. Is there a problem?"
Song Han replied irritably and continued to lead them towards the energy room.
"The raw material rods produced contain many elements. If uranium is extracted from them, fuel rods can be refined for nuclear reaction power generation.
This room is a small nuclear power plant that is currently in operation."
Fang Jie looked at the scene in the room and pursed his lips. It really looked quite realistic.
"What's that room? I don't remember there being one last year."
Song Han led them over and introduced, "This is the demonstration scene of the future fifth-generation small nuclear power plant. In the nuclear fission reaction, the fission of uranium elements will change the properties of substances. In a thermal neutron reactor, thorium 232 is converted into uranium 233, and then uranium 233 undergoes a fission reaction to release energy and is reduced back to thorium 232.
Limited by the site, it's not possible to integrate the two reactors. So, two reactors are set up, one uranium 233 reactor and one thorium 232 reactor."
Fang Jie looked at the scene in the room without understanding. Only the data constantly jumping on the display screen hanging on the curtain wall could make him feel the changes.
"So perfunctory! They didn't even make a sectional view. Looking at the big iron cans through the glass, it looks like it's real."
Song Han shrugged and didn't explain anything, leading them to the next viewing point.
"This is the information center. You can complete the modeling and design of living and production materials here, and then the design drawings will be automatically imported into the production workshop for production.
It demonstrates the future Industry 4.0 highly flexible production model.
You can also design and make a souvenir here and take it out for free."
Hearing Song Han's introduction, Fang Jie's eyes lit up. He raised his hand and asked, "Can you take us to the production workshop to have a look?"
Song Han indifferently led them towards the mechanical processing area.
Through the glass wall, a machining center was running silently, and there were several mechanical dogs with robotic arms moving the materials around.
Fang Jie stared fixedly at the nameplate on the machine tool of the machining center and said in disbelief, "SKF multi-axis linkage??"
Song Han looked at the other person in surprise.
"What's your major?"
"Die Design and Manufacturing."
"No wonder!"
"Brother! Brother! Can you give me your boss's contact information?"
Fang Jie leaned close to Song Han and said excitedly, "The SKF multi-axis linkage machining center is equipment that is prohibited from being exported to our country by the Wassenaar Arrangement. If you can get this thing, why are you still running this lousy science and technology museum!
You can easily make several times the profit by reselling it!"
Seeing that Song Han was unmoved, Fang Jie leaned forward and whispered, "Don't worry, brother. I won't ask for your boss's contact information for nothing. I'll introduce a big business to your boss. You'll definitely get your share if it's successful later."
Upon hearing this, Song Han raised his eyebrows and asked, "How much?"
"This amount!"
He stretched out his finger and made a gesture.
"Eight hundred thousand?"
"Uh... eighty thousand!"
"No interest."
Song Han turned around and walked away.
"Don't go, don't go, brother!"
Fang Jie ran up and chattered on, "That's eighty thousand yuan!
With eighty thousand yuan, why are you still working as a lousy tour guide? How much is your monthly salary?"
Song Han looked at Fang Jie who was holding him and frowned. "First, I don't have my boss's contact information. If you have something to do, you can directly contact our company through the official website.
Second, my monthly salary is three hundred thousand yuan. Should I be proud of that?"
"How much?"
Fang Jie's voice cracked in surprise.
Song Han calculated the financial rewards for his tasks in the past two months. After his strong argument, as long as he completed the literature reading tasks issued by the system, he could get cash rewards ranging from hundreds of thousands to millions of yuan every day. The specific amount depended on the time of early completion.
However, it was a pity that whenever he had some ideas and needed to consult the system, it would deduct a part of the rewards. According to the system, this was the reward that the host needed to pay for assigning tasks to the system.
Although the amount deducted was much more than the reward each time, just because he could assign tasks to the system, Song Han was willing to be deducted.
"What's so strange about three hundred thousand yuan?"
"You're just a lousy tour guide, and you get three hundred thousand yuan a month? Is your boss crazy?"
Song Han stood with his chest out and adjusted his white coat.
"Let me introduce myself again. I'm the curator of the Future Science and Technology Museum!"
Looking at Song Han's young face and messy hair on his head, Fang Jie pursed his lips for a long time before retorting, "Brother, is your science and technology museum hiring?"
