Super Rich: Starting the game by going back ten years to buy Bitcoin

The moment the laser struck the carbon fiber titanium alloy surface, a metallic hiss pierced the entire laboratory.

Li Yichen wore a protective mask and held a cutting pen. The blue light followed a pre-set path, sparks flying. He didn't rush to cut the skeleton.

First, build the heart.

He cleared an entire wall of space on the control panel. Pressing the wristwatch, Ling'er activated the holographic projection—an exploded view of the complete structure of the miniature hydrogen fuel cell unfolded in the air. Thousands of components floated before her eyes, disassembled layer by layer from the outer shell to the core.

Proton exchange membrane. Membrane electrode assembly. Catalyst layer. Gas diffusion layer. Bipolar plate. Sealing gasket. Hydrogen storage module.

Each part is marked with precision down to the nanometer level.

Li Yichen pulled over the microscopic operating table and brought up the process parameters for the first component. He slipped his fingers inside the operating glove and stared through the eyepiece at the membrane surface magnified three hundred times.

start.

Ling'er hovered above the right side of the control panel, her two large eyes fixed on the laboratory's environmental monitoring panel. Temperature, humidity, and cleanliness—three sets of data fluctuated in real time.

"Brother, the temperature is 0.3 degrees higher than usual."

Turn on the air conditioning.

"It has been adjusted."

The first day has passed just like that.

Day three.

Seven discarded proton exchange membranes were placed on the operating table.

Each one had the same problem—insufficient dispersion of platinum nanoparticles in the catalyst layer, resulting in severe agglomeration. The electrochemically active area was only 60% of the theoretical value.

Seven pieces.

More than 30 million rare materials were turned into waste.

Li Yichen sat on the stool, his shoulders slumped forward. The microscope's eyepiece had left a red mark on his forehead. He stared at the last failed sample for a full twenty minutes.

Ling'er perched on his shoulder, her little face close to his ear.

"Brother, do you want to rest for a bit?"

He did not answer.

My mind was racing. The catalyst ink formula was fine, and the solvent ratio was the standard value given by the system. Thirty minutes of ultrasonic dispersion should have been enough—but in practice, the laboratory equipment's power was a level lower than the system's preset level.

Thirty minutes is not enough.

Li Yichen stood up. He walked to the ultrasonic disperser and changed the parameters from thirty minutes to forty-five minutes. He also made a minor adjustment to the solvent ratio, increasing the proportion of ethylene glycol by two percentage points.

The eighth time.

Under a microscope, platinum nanoparticles are uniformly distributed on the surface of the carbon support. There is no aggregation. Active area: 97.6%.

"Passed."

Ling'er did a somersault in mid-air.

Seventh day.

Hydrogen storage module.

A high-pressure tank the size of a fist. Working pressure: 700 atmospheres.

The booster pump starts. The numbers jump up.

100. ​​200. 300. 400.

500.

A very faint hissing sound came from the seam.

Li Yichen was launched three meters away, his back slamming against the wall. At the same instant, Ling'er shut off the pressurization system. The pump stopped. The numbers froze at 503.

There was a three-second silence in the lab.

The hissing sound also disappeared.

Li Yichen leaned against the wall, his chest heaving. He stared at the fist-sized silver tank on the control panel.

If we hadn't stopped, and continued pressurizing to 700, this lab would have become a pit.

"Brother, are you alright?" Ling'er floated in front of him and placed her little hand on the tip of his nose.

"fine."

He went back and removed the sealing ring. It was made of fluororubber, which had undergone slight deformation under ultra-high pressure. The precision was insufficient.

Change.

Military-grade perfluoroelastomer rubber. The sealing surface has been re-machined, improving the precision from 1 micrometer to 0.1 micrometers.

Second pressurization.

8.8.4.4

Not moving.

Li Yichen stared at the number 750 on the pressure gauge. He breathed a sigh of relief.

Day 10. 2 AM.

On the control panel.

A fist-sized, entirely silver-white cylinder lay there quietly. Its surface was polished, gleaming coldly under the incandescent light. At each end was a set of miniature output terminals with gold-plated contacts.

Miniature hydrogen fuel cells.

Li Yichen picked up the multimeter. He connected the probes to the positive and negative terminals.

The reading pops up.

He stopped.

Power density – 8% higher than theoretically calculated.

This fist-sized device has enough power to drive a heavy-duty truck. Its range, under normal load, exceeds three years.

Three years.

No charging required. No battery swapping required. Fist-sized. Three years.

Ling'er was bouncing around beside her, her ponytail swinging like a spinning top.

"Brother is amazing! The strongest battery in all of humanity! Bar none!"

Li Yichen held the battery up to the light. The silvery-white casing reflected his face—stubble was showing, and his eye sockets were somewhat deep.

He smiled and put the battery back into the shockproof box.

The heart is built. Next, the bones will be built.

Day 11.

The five-axis CNC machine tool roared. The carbon fiber titanium alloy prefabricated plate was locked in place by the fixture. Ling'er projected a holographic guide line of the left forearm skeleton into the air—a blue dotted line suspended three centimeters above the plate.

Li Yichen raised the laser cutting pen and aligned it with the starting point of the guide line.

Press the switch.

Blue light fell. Metal hissed. Sparks shot out from the cut, hitting the protective mask with a crackling sound.

One millimeter. One millimeter.

The texture of the carbon fiber layers is exposed on the cut surface, so dense it shines.

After each sheet is cut, it needs to be placed on a hand grinding table. The diamond grinding wheel is turned to its lowest speed, and the mating surfaces are rubbed little by little. The precision is within 5 micrometers. Even a slight deviation is unacceptable.

Day 18.

Left forearm. Done.

A silver-gray robotic arm rests on a support. From the elbow to the fingertips, twenty-eight miniature hydraulic cylinders are embedded in the joints. Twenty-eight degrees of freedom. Six more than a human arm.

Li Yichen connected the hydrogen fuel cell. The power supply interface engaged.

start up.

hum.

The mechanical fingers bend, extend, rotate, adduct, and abduct in sequence.

He picked up a 0.3-millimeter copper wire from the table. He clamped it firmly. There was no tremor.

Then he put his left arm on.

Flexible electrodes adhere to the skin. Microcurrents penetrate the peripheral nerves. A tingling sensation spreads from the elbow crease to the fingertips.

He moved his index finger.

The robotic arm responds synchronously. The latency is less than 5 milliseconds.

He clenched his fist.

It slammed into the ten-centimeter-thick steel plate next to the control panel.

boom.

A fist-sized dent was left on the surface of the steel plate. It was four centimeters deep. The metal at the edge was squeezed and curled up.

Li Yichen looked at the fist mark. A slight smirk appeared on his face.

Day 25.

Left calf module.

The hydraulic cylinders in the legs are three times larger than those in the arms, resulting in greater load-bearing capacity.

Slip it on. The buckle snaps shut. The entire leg is encased in silver-gray metal.

Li Yichen stood up. He tapped his toes on the ground.

Try jumping.

boom!

He was launched upwards. Three meters. His head barely grazed the ceiling.

Landing.

The epoxy resin floor cracked with spiderweb-like fissures. Debris flew everywhere.

Ling'er screamed, "Brother, watch out! The ceiling! Another half-beat higher and your head will be embedded in it!"

Li Yichen squatted on the cracked ground, catching his breath. He looked down at his left leg, which was encased in an exoskeleton.

"Power output... still needs calibration."

Day 32.

Chest armor and back power unit.

The most complex part. The main power supply module of the hydrogen fuel cell is embedded in the spine, and carbon nanotube wires distribute power to the limbs. Sensors are densely packed on the inner side of the sternum to collect electromyographic signals and postural data in real time.

Installation took seven hours.

The power transmission line is short-circuited.

The electric arc broke through the protective insulation layer. The sparks burned directly onto the web of the left hand.

The smell of burning flesh filled the air. The skin and flesh were rolled up, a mixture of red and white.

Li Yichen gritted his teeth and pulled his hand out. He rushed to the sink, turned the cold water on full blast, and rinsed himself for three minutes. Then he tore open a medical gel dressing and applied it.

Ling'er jumped around anxiously in mid-air, crying, "Brother, please rest! You're burning up like this!"

He flipped the breastplate over with his right hand. He located the short circuit. The insulation of a wire had been damaged by the high temperature during soldering.

Replace the cable. Resolder. Continue.

Day 40.

helmet.

The last component.

Built-in miniature holographic display. Vital signs monitoring. Communication system. Ling'er's local computing terminal.

Tighten the last tiny screw.

Li Yichen put down his tools and took two steps back.

On the humanoid support in front of me—

A complete exoskeleton armor stood silently under the white light.

Silver-gray. Streamlined design. Broad shoulders, limbs that follow the contours of human muscles. The slightly raised power unit on the back has a clean silhouette. The helmet visor is V-shaped, with dark black ballistic composite material covering the face.

It is 1.92 meters tall.

Li Yichen stood before it. Forty days. His hands were covered in burns, scratches, and new calluses. Metal dust that couldn't be washed off was embedded in his fingernails. He had lost a lot of weight.

Ling'er floated onto the armor's shoulder, lay down on it, and pressed her face against the cold metal.

"Brother, it's so cool."

"Um."

Li Yichen pressed his palm against the breastplate. The metal was cold.

"Ling'er".

"exist!"

"Start the wearable application."

All the fasteners on the support frame pop open simultaneously. The chest armor separates front and back. The joint locks on the limb modules disengage. The shoulder armor flips upward.

Li Yichen turned around. His back pressed against hers.

The neural interface in the spinal position is automatically aligned. Flexible electrodes conform to the skin. Microcurrent is inserted.

A tingling sensation shot from the tailbone to the back of the neck.

The breastplate closes. Click.

The pauldrons fell. Click.

Thigh. Calf. Upper arm. Forearm. Palm.

Each module is put into place with a crisp mechanical click.

The helmet popped out from the top of the stand. Li Yichen caught it. He raised both hands above his head and slowly pulled it down.

The mask fell down.

A shift in perspective.

The HUD holographic interface lights up at the edge of the field of view. Blue characters float—power output percentage, hydrogen fuel remaining, external temperature, and hydraulic status of each joint. All data changes in real time.

Ling'er jumped to the upper right corner of the HUD and sat down, hugging her knees.

"System self-check complete. Everything normal." She blinked. "Brother, you look incredibly handsome right now."

Li Yichen slowly clenched his fist.

The hydraulic system responds. Fingers close. A mechanical groan emanates from the joints, deep and resonant.

He raised his arm. He could barely feel the weight of the armor. Power surged through every bone, filling his limbs to their limit.

Data shows: Current output mode - 10%.

Only ten percent.

He turned his neck, looking towards the reinforced door deep within the laboratory leading to the underground testing grounds. It was made of three layers of alloy steel plates, half a meter thick.

Ling'er jumped to the front of him, holding up a virtual sign with her two little hands.

The four crooked characters above read "First Flight Test".

"Are you ready, brother?"

Li Yichen raised his right foot.

Take that step.

The metal soles of the boots touched the ground.

The muffled sound penetrated the entire laboratory, spreading along the walls, and even the light tubes on the ceiling trembled.
