Myriad Heavens: Rise of the Rune God-Chapter 100: Breakthroughs

"Keep improving ORION," Orion said. "Add more physics models. Increase simulation accuracy. Make it capable of handling more complex systems."

"Understood. I will continue development."

Orion checked the time. 6:47 AM. He’d worked through the entire night.

His body felt fine though. The breathing technique kept his cells energized, his mind sharp. No fatigue at all.

He should probably eat something.

And just in time.

"Orion! Breakfast!" Cassia’s voice from downstairs.

Perfect timing.

He went down to the kitchen. Cassia had set the table—eggs, toast, fruit. She was already sitting, tablet in hand, completely absorbed.

"Morning," Orion said, sitting down.

"Mm." She didn’t look up. Her fingers swiped across the tablet screen. Eyes focused.

Orion started eating. The eggs were good. His enhanced senses picked up every flavor—butter, salt, a hint of pepper.

Cassia kept exploring the tablet. Opening apps, testing features, reading through menus. Her expression shifted between concentration and amazement.

"This photo editing app..." she muttered. "How does it know exactly what I want to change?"

Orion smiled. The AI assistance was working perfectly. Learning user patterns, predicting needs, making suggestions.

She opened another app. A game this time. Started playing. Her eyes widened at the graphics.

"This runs on a tablet?" She looked up briefly. "These graphics should need a high-end gaming PC."

"Dimensional compression," Orion said. "Plus efficient code."

"It’s incredible." She went back to exploring.

Orion finished breakfast. Cassia barely noticed. She was testing the video editor now, completely absorbed.

He left her to her devices and went back to his room.

"Alright Rene, let’s keep going. We need to test the reactor design properly."

"Shall I activate the full simulation environment?"

"Yeah. Let’s do this right. I haven’t tested this feature yet after I made the BCI."

Signals came through the BCI. Not just data this time—something different.

Rene was sending electrical patterns directly to his brain. Specific signals designed to trick his senses. His eyes, ears, touch—all receiving inputs that weren’t real.

The world around him changed.

His bedroom disappeared. Replaced by a virtual laboratory. White walls, clean floors, high-tech equipment everywhere. It looked completely real.

Orion reached out. Touched a virtual table. His brain registered the sensation—smooth, solid, cold metal. But his actual hand was touching nothing. Just air.

"This is amazing," he said. His voice echoed in the virtual space.

"I am generating sensory data that bypasses your normal perception," Rene explained. Her voice came from everywhere and nowhere. "Your brain believes it is experiencing a physical environment. This allows for much faster research and development. You can manipulate virtual objects as if they were real."

Orion looked around. Holographic displays floated in the air. Equipment he could use. A complete laboratory at his mental fingertips.

"Pull up existing fusion reactor design. Let’s start working."

A large hologram appeared in front of him. The ITER fusion reactor design—massive, complex, beautiful.

But after the knowledge he had studied in the library, it now looked like scrap metal and also totally inefficient.

"This design is too complicated," Orion said, studying it. "Look at all these parts. The twisted magnetic coils, the complex containment geometry. They needed all that because their components weren’t good enough."

He waved his hand. The hologram changed, showing the internal structure. The plasma containment, the cooling systems, the power conversion.

"And this," Orion pointed at the power generation system. "They’re using steam turbines. Creating temperatures hotter than the sun just to boil water."

"Traditional thermal conversion," Rene said. "Fusion plasma heats water, water becomes steam, steam spins turbines, turbines generate electricity. Approximately 30-40% efficient."

"That’s stupid. We’re wasting most of the energy to heat dissipation."

Orion started redesigning in his mind. The virtual environment responded, changing the hologram based on his thoughts.

"What if we skip all that? Convert heat directly to electricity?"

"Thermoelectric materials," Rene said. "They generate electricity when one side is hot and the other side is cold."

"Exactly."

Data appeared around him. Information about thermoelectric materials. How they worked, their properties, their limitations.

Thermoelectric materials used something called the Seebeck effect. Simple principle: heat one side, keep the other side cold, electrons flow from hot to cold. That flow was electricity.

Like a battery powered by temperature difference.

Current thermoelectric materials were terrible though. Best commercial ones converted maybe 10-15% of heat to electricity. Some experimental materials in labs hit 20%.

Still worse than steam turbines.

"We need better materials," Orion said. "Show me the problems."

Information organized itself in the virtual space. Three key requirements for good thermoelectric materials:

High electrical conductivity - let electrons flow easily

Low thermal conductivity - keep hot side hot and cold side cold

High Seebeck coefficient - generate lots of voltage per degree of temperature

"The problem," Rene explained, "is that materials good at conducting electricity are also good at conducting heat. Like metal—excellent for electricity, terrible for maintaining temperature differences."

"It’s like wanting a door that’s open and closed at the same time," Orion muttered.

He pulled up research from the library knowledge. Found something called "phonon-glass electron-crystal" materials.

Phonons were basically tiny sound vibrations at the atomic level—how heat moved through solids. Electrons were electricity.

The ideal material would block phonons like glass blocks light, but let electrons flow like crystal conducts electricity.

"Can we design something like that?" Orion asked.

"Loading ORION simulation now."

The virtual laboratory expanded. Atomic-scale visualization appeared. Orion could see individual atoms floating in space.

He started building materials atom by atom.

Tried bismuth telluride first—a real thermoelectric material currently used. Not efficient enough.

Added other elements. Antimony. Skutterudite compounds with cobalt and nickel. Created layered structures.

The key was engineering at the atomic level. Make the material block heat vibrations while letting electrons flow freely.

He designed a superlattice—repeating layers of different materials, each just a few atoms thick. Metal layer, insulator layer, metal layer. Over and over.

At that tiny scale, quantum mechanics took over. Electrons could tunnel through the insulator layers like ghosts passing through walls. But heat vibrations couldn’t—they scattered at the boundaries between layers.

Like building a road for cars that had speed bumps for trucks. Cars sailed through smoothly. Trucks got stopped.

Orion worked obsessively. Trying different combinations. Adjusting layer thicknesses. Testing each design in simulation.

His enhanced brain processed thousands of material combinations. ORION ran simulations in parallel, testing everything virtually.

Hours passed. He barely noticed.

In the real world, Cassia knocked on his door. Brought food. Asked if he was okay.

"I’m fine," he said, briefly exiting the simulation. "Just working."

She looked concerned but didn’t push.

He went back into the virtual laboratory.

Finally, he found it.

The simulation showed a material with incredible properties:

Electrical conductivity: 10,000 S/m (excellent) Thermal conductivity: 0.5 W/mK (terrible—which was perfect for this) Seebeck coefficient: 450 μV/K (outstanding)

He ran the efficiency calculation.

80.3% heat-to-electricity conversion.

Orion stared at the number. Ran it again. Same result.

"Rene, verify this. Make sure the simulation is accurate."

"Running verification protocols... Physics models validated. Material properties confirmed. Efficiency calculation correct. The design is viable."

Eighty percent efficiency.

Current thermoelectric materials topped out at 15%. This was more than five times better.

This would change everything.

"What’s the composition?" Orion asked.

The formula appeared in glowing text. Layers of bismuth telluride doped with antimony, alternating with skutterudite compounds containing cobalt and nickel. Each layer exactly 15 atoms thick. Specific crystal orientation. Precise doping ratios.

"Is it difficult to manufacture?"

"Surprisingly, no," Rene said. "The layering can be achieved through molecular beam epitaxy—a standard technique in semiconductor fabrication. The materials are relatively common. Cost would be reasonable at scale."

Orion pulled up the fusion reactor design hologram. Started redesigning it around the new thermoelectric material.

Old design was complicated:

Fusion plasma (100 million degrees) → First wall made of tungsten → Breeding blanket to absorb heat → Coolant channels with water → Heat exchanger → Steam generator → Turbine spinning → Generator making electricity

Seven steps. Massive infrastructure. Buildings full of equipment.

New design:

Fusion plasma (100 million degrees) → Thermoelectric blanket directly converts heat to electricity → Cooling system on back side keeps it at proper temperature → Electricity output

Three steps. No turbines. No steam. No moving parts that could break.

The thermoelectric blanket would surround the plasma like a shell. Hot side facing the fusion reaction, reaching 2000°C from the heat. Cold side cooled by water, kept at 50-100°C.

Temperature difference: about 1900°C.

With 80% efficiency, it would convert nearly all that heat directly to electricity.

"This is brilliant," Orion said. "We eliminate the entire thermal conversion system. Just fusion core plus thermoelectric shell. The whole reactor could fit in a building the size of a warehouse instead of a stadium."

"Correct," Rene confirmed. "The design is approximately 70% smaller than conventional fusion reactors with equivalent power output."

"And more reliable. No moving parts means nothing to break down."

"Additionally, the solid-state conversion allows instant power adjustment. No waiting for turbines to spin up or down."

Orion redesigned the reactor shape too. Instead of the complicated twisted designs from ITER, he used something simple: a donut shape. Just a ring.

With the advanced components he was designing—the thermoelectric materials, the superconductors he’d work on next—there was no need for complex geometry. A simple donut would contain the plasma just fine.

The magnetic fields would wrap around the donut, containing the plasma inside. The thermoelectric blanket would line the inner wall, converting heat to electricity.

Simple. Elegant. Efficient.

"Show me the full design," Orion said.

The hologram updated. A perfect donut-shaped reactor. Maybe 10 meters in diameter. Thermoelectric blanket glowing orange from heat. Magnetic coils wrapped around it. Cooling systems on the outside.

Power output: 1000 megawatts continuous. Enough to power an entire city.

Fuel: Deuterium. Everywhere in seawater, easy to extract. Effectively unlimited.

Waste: Helium. Completely harmless. Could be sold for industrial use.

No carbon emissions. No radioactive waste. Just clean, endless energy.

"We’re getting close," Orion said. "But there’s more work to do. The magnetic containment needs better superconductors. The plasma control needs better AI systems. The materials need to be manufactured and tested."

"Agreed. Shall we continue?"

"Not yet. I need a break."

Orion exited the simulation. The virtual laboratory faded. His bedroom appeared around him again.

He pulled off the earbuds. Stood up. Stretched.

His body felt fine—the breathing technique kept him energized. But his mind needed a moment to process everything.

Two major breakthroughs in one night. The simulation software and the thermoelectric material.

Three years to build a fusion reactor.

He was going to make it.
