— Let's go up.

Jaon and Alan walked into the elevator and went up.

They were silent until Jaon broke the ice by criticizing Alan.

— You smell terrible. Before you work, go wash. — Now that they're closed in a small space, Jaon could feel how bad Alan smelled. — May I know what causes it?

— It's sweat. Unlike in your organism, we use sweat to cool and not throw useless chemicals away. — Etia always gave Alan drinks from her hair, which was just water with an indigestible carbohydrate. Humans have no problem with absorbing it, though.

— Interesting.

The elevator arrived at its destination. The door opened automatically and allowed Alan to see the mansion.

He never had the chance to see the White House, especially after the Washington riots, but this is how he imagined it to look. Everything was clean and shiny to an uncanny level. White sheets covered the windows and a few maids were making sure that no dust was freelancing inside the house.

— Ad, lead him to the bathroom, please. — Jaon ordered one of the maids, and she stopped her work.

— Yes, sir, Ux. — She wore a white cleaning uniform covering her whole body. The only part one could see her face. — Please follow me, Mr… — she stopped speaking and waited for Alan to finish.

— Alan Coello.

— Addo. — she introduced herself back and started walking toward a giant staircase.

It took them less than three minutes to reach a small room with a bath and a few bottles of shampoo.

— Thank you for leading me here. — Alan said, before closing the door and undressing.

He looked at his body and willed for all the implants to reveal themselves. Small plates made from a magnesium alloy covered his skin. Steel could never pierce them, and sapphire could never scratch them.

This novel's true home is a different platform. Support the author by finding it there.

Long, thin blades jumped out of his arms and shone with a silver luster caused by refined titanium. Their sharp edges threatened everything softer than diamonds. No armor could stop them. No sword could dull them.

“Check for invaders” Alan spoke to his main computer. There was no answer, meaning that it didn't find any malfunctions. “Stop”

He had to input most commands manually. If he allowed the system to control his implants, it would disconnect over 50% of his body. In order to modify his organism to this state, the Sun Guards had to turn off most security measures. This meant that Alan had to do everything that an average person could use a computer for.

— Retract. — The blades, plates, lights, and wires all listened, which made him look like a robot pretending to be a person born of flesh and blood. That assumption wouldn't be far off because, by the NATO 2072 calcification and definition book, he no longer had human rights.

Alan got closer to the bathtub and turned on the tap. Surprisingly, clear water came out. He waited for it to fill and walked in.

— It's sweet. — Jaon probably saw him drinking from Etia's hair and assumed he could also bathe in it.

Alan got out, came closer to a nearby sink, and turned it on. This time, normal pink water came out. He used it to wash over and took a shampoo bottle to clean his whole body. It took him very little time to end.

He quickly got dressed and allowed his bathwater to drain.

— Thanks. — Alan was glad it was prepared, but he had to disclose later that he doesn't like having a sticky body.

----------------------------------------

— Let's start with units of measurement. — Alan took out a paper. — for mass, we have kilograms. — He pulled a bullet out of his gun and showed it to Jaon. — This weighs 2 milligrams. Ten of these, 2 grams…

Alan explained how much mass a kilogram has.

— Interesting. It makes a lot more sense than what we have in place. — Zhar used a system similar to the Imperial system. It was a novel idea to use sets of tens.

— Next, let's get onto time. A blinker will appear. It will turn on and off every second. — A small lightbulb revealed itself from Alan's chest. It was meant to show only when a critical error occurred.

Jaon took out a camera and filmed the light. Some time passed and Alan started speaking again.

— Now, let's go for distance. Meters are the unit. Do you know the speed of light? — Alan wanted to define a meter with a small equation.

— Yes, I do.

After hearing that, Alan wrote the equation for the speed of light.

— Each second, light passes this many meters. — Alan quickly explained. — can I go now?

— Yes. — Jaon started looking at Alan's and his notes.

In a few seconds, Alan ran out of The office and made his way toward the room he was assigned to.

— Hey. — He opened the door and saw Etia sitting on a double bed.

— I missed you. — She replied, before standing up and hugging him.
