just why?

4 months later they had about 11 acres of greenhouse, corn, wheat and vegetables filled them. An had decided she would plant fruits last. He on the other hand had been working on his laser weapons.

Before him stood two fist sized black metal balls with holes. They were the lasers he remembered from the movies. When activated they released wire like thin lasers.

Unlike the guns they did not shoot pure mana. He had experimenting on combining the technology from his memories with the rune from this world.

The laser balls are his first success. He drew the simplest mortal grade lighting runes and arranged them to form a sequence. Normally drawing a sequence with mortal grade runes would be impossible.

Well to be honest what he did could barely be called a sequence, it more like a very complicated formation. He translated the rune language into a language of codes.

The runic language was not hard if you learnt it but drawing specific commands was the problem. The language only had specific words derived from nature like the elements.

There have been runes not created by nature like the runes depecting weapons. This nature of runes makes it impossible to create a self running system based on simple coding. The artefacts here needed to be runned by people.

He really admired the people from his memories for creating something that even the old monsters of this world could not and now he was going to use their gunius for himself.

He broke down the runes and rearranged them. It was like separating words into individual letters, although he made it sound easy it was anything but. Runes are super resistant to change.

It had taken him four whole months but he was finally done. His first coded creation was the laser defence system, he also programmed motion sensors into it.

The motion sensors were different from the one he remembers, they don't sense infrared energy but vibrations, the smallest disturbance in the air or ground would be detected by them.

The balls were filled with pure silver wires, he realised silver was the best mortal grade metal to conduct lightning so using them might make the entire system function better.

Using electrical energy as the main source saved him a lot of mana while also reducing certain limits like the strain active runes placed on souls. An initiate would not be able to use active runes of master grade as that would hurt if not outright fracture their souls.

However with this, things are different, firstly the runes are all low grade, although the fragments of the ruses are weaker than the runes when he rearranged them into a system, the whole system is more efficient than individual runes.

Although not necessarily more powerful it more easier to use, even by weaker people. Another reason is the technological parts, the lighting runes that power the system is of mortal grade and since the energy is transferred by wires it doesn't need the energy transference runes, which was one of the reason making a mortal grade sequence was hard.

He also skipped the energy conversion runes which are also higher grade runes thus saving even more energy. Infact the only runes drawn here are the the lighting runes.

Near the holes of the balls were filaments, thin wires, when the electrical currents pass through them they hear up and glow. A single mortal grade lighting rune can produce about 5 million volts.

Due to his high perception, he had drawn millions of them at microscopic level. Unlike magic circles, the size of runes does not matter, they still produce the same amount of power.

The intensity of the heat and light from the filament is insane due to the high electricity passing through it, that why it can be released as a condensed thin ray of superheated light.

It normal usage would only use about 40% of the runes, that would last a rank 2 mana core about a year if the lasers were constantly on which he doubt will be the case and it normal power will probably be around the acolyte level, without will It will be weaker than normal acolyte.

When all of the runes are used at the same time it will reach master realm for about 30 seconds. He was quite impressed with it. Now it was time to work on something else, the laser gun or a mech suits.

Mech suit sounds cooler, I'll go with that but first I have to make cameras and a TV? He wasn't sure if that what it was called but it did look like a TV. So he started.

It took him a few days to make a camera, in this world, there was something called crystal balls that are used to capture images and a technique was used to transfer those images like projections.

The issue wasn't that, he could easily use those balls but they released a signal making them hard to miss, they could not be used as spy cameras and he couldn't have that.

He needed the target to not discover them. After he was done making a camera that could transmit real life images to a small glass tablet he had made.

Well that was that, it was time to do his noble job as the great man that he is and test these things. He went outside and called a bunch of kids playing in the snow.

They rushed towards him, he still has his dark armour on and looked really scary but the kids were not terrified of him, infact they started throwing snowballs at him the instant he called them shouting defeat the demon king.

He played with them for a while pretending to be an evil demon king before handing them the tiny cameras, the lenses could move around to catch what around it. He told the kids to place them randomly across the village.

He went back inside and took off his armour, it was actually the first time since he got here that he took it off. What appeared was a young man with white skin and gold eyes. He had an average look with silky black hair.

This is getting ichy, he mumbled before touching his face and ripping his skin off. It wasn't actually his skin but a plastic like think cover that changed his look. His real self appeared.

He was actually dark skinned like the people of the Sun from the south, thick lips and a broader nose. What made him different from the Sun people though was his eyes and hair theirs were grey, black or brown while his were gold.

While even though their hair was hard and grew straight up, his was silky like those of the empire, that was not due to changing his appearance it was naturally like that. Feels good to be in my true self again, he said softly.

Then he called all the other crafters to watch his new creation. Yamiko was close by so she also came. Well then let start, when he opened the tablet the first thing he saw made him flabbergasted. He felt a chill behind, he turned his head slowly and Yamiko was standing with a smile that not a smile. Well, fuck, he thought.
