Crossing the World
IV - Earth (Karen)

In this world the most widely used energy sources are crude oil and coal. Some use nuclear, but apparently not too much existing nuclear material and some leaks result in a city becoming a dead city.

Oil and coal are not actually good materials for energy. Both of these substances produce harmful pollution that will damage the planet over time. It is only natural that global warming is occurring and some people are starting to undertake high-value projects that they call terraformars.

Unlike the Earth, the shelter uses water as fuel. Of course, not just use it immediately considering that water is one of the most stable materials ever.

We separate hydrogen and oxygen using the electrolysis method. Then, these two substances will be reacted to produce water and electrical energy. Well, this electricity is the main power source of the shelter.

Why don't we use the power source used for electrolysis?

It's actually a bit complicated and I still can't understand it completely. Simply put we have a battery that stores primordial electrons, which is one of the raw energies that cannot be used. Primordial electrons can be used to separate hydrogen and oxygen, but cannot be used on any electronic device. As a result, we use it for chemical reactions in water separation.

This is what I'm trying to build right now. People used to call it a converter, which is a water splitting device while converting hydrogen into electricity which can then be used to charge my teleporter.

Now is the fifth day I'm stranded here. A little bit I already know some pretty useful facts about the planet I'm on now.

This planet is called Earth. It is the third planet in the solar system and has one natural satellite. The environment is suitable to support life, but the residents began to damage the environment slowly.

Its gravity is weaker than my planet's and the air temperature is cooler. Most of these places are free of harmful radiation, but there are some places that have high radiation. The air pressure is also a bit weak so my ears are hurting right now. My nose even bled during the second day, but my adaptability managed to slightly neutralize the discomfort.

The intelligent species on this planet are referred to as humans. Physically they are very identical to me, but there are slight differences on some aspects.

Unlike me, both of their eyeballs could only focus on one point simultaneously. They also could not share their consciousness. In addition, their heads also cannot rotate 180 degrees. Maybe I would be considered a ghost if I accidentally looked back in front of a human.

The most interesting difference is that their wrists cannot rotate 360 degrees and they cannot bend their fingers backwards. Seriously, how could they not find it difficult with such limited movements?

Even though my body is small, my strength and agility are still slightly better than humans. I don't know if this is the effect of weak gravity or not, but clearly a human child with a small body like me would definitely not be able to withstand the effects of the back pressure of a submachine gun easily.

In this world there is an interesting thing called internet and ancient computers. The processor speed is slow enough that it cannot support virtual reality, but the application is quite flexible. Civilization is growing well.

I put the anode and cathode into the glass tube I just picked up from inside the T-13. Fortunately, the tube was not damaged and the battery was still fully charged with primordial electrons. Looks like I can charge about 10% with this amount.

After finishing with the simple converter I made over the past five days, I started to take it out of the forest.

The container is filled with seawater until the anode and cathode are submerged. Then, I brought back the water-filled converter into the forest where I made a temporary shelter.

In the sea, there is not only water. Salt is also one of the largest compounds that make up sea water. However, as far as I know salt will be difficult to reduce when the electrolysis process occurs so that the possibility of the formation of sodium metal is small. This happens because water is much easier to reduce.

Reduced water at the cathode produces hydrogen while the anode produces oxygen. The hydrogen is then stored in the next tube and sent to another anode. Oxygen electrolysis will also be pumped through the cathode in the same tube so that it oxidizes hydrogen thanks to the help of electrolytic fluid that serves as a separator between the anode and the cathode. As a result of combustion, the two elements will produce water, heat, and electrical energy. The water, which is usually hot steam, is removed from the tube to pass through the condenser system before it is finally reused in the electrolysis process and the electricity generated will be used to charge the teleporter.

Well, that's about how this tube I'm carrying works.

I kept a canister by the fireplace last night. Then, I removed one of my gloves and connected it to the cable in the tube. After checking it once more and being sure that everything was properly installed, I pressed the button to start the conversion process.

Both gloves are connected wirelessly. So, when one of them charges, the other glove will be charged. This is why I only filled one of them.

Not long after I pressed the button on the converter, a line of virtual writing began to appear before me.

[Filling is being done. Estimated charging to full is one month]

Since the battery power is not too much, I do not really expect that the charging will be able to be done to the full. I only need five percent to get home. If it turns out that the converter can fill up to ten percent, I will bring along the seawater to the shelter.

After being stranded here for five days, I later learned that I was actually on a small, empty island. The intelligent species in this place is just me and the nearest island from here is about two kilometers away. However, the island is also uninhabited. Therefore, I chose to hunt when my stomach started to get hungry and distill the seawater to drink. It's lucky for me that all the rifles are still working and my bullets are pretty much left.

"Ah, that's a squirrel, isn't it?"

I've seen it on the internet. It seems that a lot of people like squirrels because they think squirrels are cute. I'm sorry, in a place where it requires me to survive, there's no such thing as a funny animal. Everything is food!

I shot him without any difficulty. The bullet pierced his head and made him fall to the ground.

"Hoho~ today high quality animal meat again!"

I picked up the poor squirrel and continued my hunt.

When I was living with other refugees in the shelter, the animals and trees were very limited. So, consuming animal meat and fresh vegetables is a very luxurious thing. Instead, we have synthetic meats and artificial vegetables added with nutrient fluids. However, the taste of the food was rather horrible. It was fortunate that I was able to eat as much as possible without worrying about food stocks.

I chose to burn the meat I had cleaned before. The roof is sea water and grass around. I also brought some strange fruit that has been verified can be eaten as dessert.

Today also passed with a full meal and sleep late at night.

By the seventh day, my ears had adapted well. The discomfort in my body is now almost completely gone.

I checked my teleporter to see how much power it had charged. It seems that the power I have now is seven percent. If it continues like this, tomorrow I can go home and bring water for the purposes of the shelter.

Like the days before, my morning schedule was to surf the internet to gather information. I'm very interested in all life on this planet. It's possible that one day I could make a useful trade considering that they have very abundant water.

"Electron primordial batteries will definitely be very sold in this world."

It's a pity that the primordial electron is not renewable energy. That energy was created when my planet was exposed to cosmic radiation tens of thousands of years ago. Now it is still abundant, but it will certainly run out quickly if I share it to this planet considering the total use of human electricity is very wasteful. It would be better if I were to trade in any other form.

"Would I just take all the water in the world?"

A very tempting choice, but it will ruin the good name of the shelter. Besides, I'm not that bad at all, so I'm going to wipe out all the inhabitants of the planet. However, if they dare to touch me first it will be another story.

"Hm?"

When I surfed the internet, there was something I was quite interested in.

"Online games, huh?"

It seems like the gaming industry is in high demand by people. Not even a few are willing to spend money to buy game items. In fact, all the games I saw were completely ancient and inflexible. How could they enjoy such a boring thing?

Ah ... wait a minute. What if I bring virtual technology into this world and create games? I can also simulate my planet to see how people solve problems there. Those who are addicted and wish to come to that virtual world I will take to my planet and let it build civilization. The terraforming process will certainly go a lot faster when compared to me alone doing it.

Well, this is a good idea and pretty crazy. However, it would not hurt if I tried all these crazy ideas. If for example there is chaos due to my technology, I just run away to the shelter and cut off contact with Earth. The worst-case scenario is that humans will annihilate each other and Earth will be destroyed like my planet. Even if it happens, it has nothing to do with me.

I spent the last day writing down my plans to build everything. Then, as the teleporter charged up to ten percent, I walked towards the sea to teleport there.

The T-13 carcass, anti-tank gun, submachine gun, and ancient converter I left here because I was too lazy to drag it near the sea. After all, those things will only become trash when I return to the shelter.

"All right, let's go home now!"

I activated a space jump, taking me and a cubic kilometer of seawater into the shelter.
