Liam exhaled slowly as he stared at the status screen, the glowing blue interface hovering in front of him like a silent invitation.

He had planned to go out to sea today — take the yacht—Mia for her maiden voyage under his ownership, feel the salt air on his face, maybe even take the helicopter for a spin over the water.

But the plan had changed.

He wanted the Omni-Science Foundation Package first.

No — he needed it first.

It wasn’t that he didn’t want to enjoy himself. But right now, every instinct told him that this was the smarter move. Once he had that knowledge in his head, the yacht trip could be more than leisure — it could be a chance to think, to plan, to start shaping the next phase of his life.

He tapped his fingers lightly on the bed beside him, considering his next move.

"System," he said after a moment, "is there anything I need to do before assimilating the knowledge package?"

The reply came at once.

[No special preparations are necessary, Host. Assimilation will take several hours —possibly up to half a day. You will be unconscious during the process. No pain will be felt, but minor discomfort is expected. The enhancement will protect your neural structure from overload.]

Liam nodded slowly. That last part was reassuring. Without the molecular enhancement, he suspected this process might turn his brain into molten mush.

"All right," he murmured.

He lay back on the bed, shifting until he found the most comfortable position.

He took a deep breath and another. And then...

"System. Purchase Omni-Science Foundation Package."

[Purchase complete. Item added to Inventory.]

His jaw tightened slightly as he gave the mental command to assimilate. He barely had time to brace himself before it hit.

It wasn’t a trickle. It wasn’t even a flood.

An ocean of information, roaring into his mind all at once.

Mathematical formulas scrawled themselves across his vision in burning light. Atomic diagrams spun like fireworks in his skull.

The periodic table expanded beyond anything Earth’s scientists had ever dreamed of — hundreds of new elements, each with their own properties, atomic weights, and potential uses.

He winced. The discomfort wasn’t sharp, but it was deep — like a weight pressing into every corner of his mind.

The data kept coming.

The laws of thermodynamics unfolded in ways he’d never imagined — ways that could be bent, rewritten, even bypassed with the right technology.

Quantum mechanics became not just a theory, but a living blueprint in his head. He could see the probabilities, feel the mathematical pulse of particle interactions.

It was dizzying. It was beautiful. It was terrifying.

Images blurred into concepts, concepts into complete blueprints. Orbital mechanics. Energy conversion systems. Fusion reactor designs. Advanced propulsion methods that could fling ships across light-years without violating causality. Genetic engineering so precise it could rewrite a species’ evolutionary trajectory in a single generation.

He gritted his teeth. "Shit..." The word slipped out under his breath as the pressure built behind his eyes.

It wasn’t pain. The system had kept its promise. But the weight of so much knowledge pressing into his mind all at once made him feel like a diver at the bottom of an ocean trench — crushing pressure, infinite depth.

And then... darkness enveloped him.

The Bellemere Mansion was quiet, but not peaceful.

In the kitchen, Evelyn was standing by the island counter, her brow faintly furrowed. Clara and Mira were nearby, going through the dinner preparations, but their movements were slower than usual.

"He hasn’t come down all day," Clara murmured, keeping her voice low.

"It’s the same as yesterday," Mira added, glancing toward the ceiling. "No lunch. No sound from upstairs."

Evelyn didn’t answer at first. She was too busy weighing her options. Dinner was in a couple of hours. Did they prepare a normal serving? Or the six full adult portions he’d devoured the night before?

Finally, she said, "We’ll wait. Start with the regular amount. If he asks for more, we’ll make it fresh."

Just then, the faint sound of footsteps drifted down from the upper floor.

Evelyn came out of the kitchen and looked up, and she saw Liam was descending the grand staircase, each step unhurried.

He didn’t look tired, exactly... but there was something about his expression. His gaze seemed distant, unfocused, as though he was still somewhere else entirely.

Evelyn’s lips curved into a polite smile. "Good evening, Mr. Liam."

He didn’t answer right away. Just gave a faint nod, his eyes still carrying that strange, far-off gleam, and continued toward the living room.

Liam sank into one of the deep leather sofas, the cushions absorbing his weight. For a long moment, he didn’t move. He just leaned back, eyes on the ceiling.

His mind was... different now. He finally understood why the system had adviced him to go through the enhancement first.

Because if he hadn’t gone through it, there was no way that his brain would had survived the first three seconds of the assimilation process.

Yes, that was how insanely massive the information contained in the knowledge package is.

Before, he’d thought of knowledge as something you accessed. You remembered facts. You recalled formulas. You looked things up.

But now? It was all there. In his head.

He didn’t have to remember how to calculate the optimal trajectory for a Mars transfer orbit — he just knew it. He didn’t have to think about how to construct a self-repairing nanofabrication system — the blueprint was already perfect in his mind.

Even now, with just a glance, he has already calculated everything about the ceiling. It was like he could see geometry in everything.

It was like having an entire civilization’s worth of scientific achievement wired directly into his neurons.

And that was the problem.

"What the hell...?" The words slipped from his mouth, low and slow.

Because he understood now, on a level he never had before, just how far he was from what humanity thought it knew.

Earth’s cutting-edge technology? The so-called frontier of human innovation? It was the equivalent of a toddler stacking wooden blocks compared to the things now swimming in his head.

He could build a computer the size of a sugar cube that would make the world’s fastest and most powerful supercomputer look like an abacus. He could design a propulsion system that could reach Pluto in hours. He could grow a building instead of constructing it, programming its materials on a molecular level.

It wasn’t just that he knew more than anyone alive. It was that he now knew too much.

And once you knew something... you couldn’t un-know it.

Liam sighed heavily as he settled his thoughts.

Evelyn reappeared in the doorway of the kitchen, breaking his thoughts.

"Dinner will be ready shortly, sir."

He blinked, then looked up at her with the faintest of smiles. "Thanks, Evelyn."

She inclined her head and stepped away, leaving him alone again.

Liam ran a hand slowly down his face and leaned back even more.

The yacht trip could wait. The world could wait. Right now, he needed time to think.

Because with the knowledge now burning quietly in the back of his mind, the real question wasn’t what he could do.

It was what he was willing to do.
