An engineer is summoned to another world. Though summoned as a hero, he possesses no special skills and is seen as rather mediocre. By chance, he acquires magical eyes that allow him to see mana. Leveraging his knowledge as an engineer along with the magic inherent to this new world, he starts creating his own unique spells by combining technology and sorcery. What will this man decipher in this unfamiliar realm? With his unorthodox expertise, perhaps he will unravel mysteries and gain deeper insights surrounded by magic. The curtain rises on an intellectual adventure, falsifying expectations of both heroism and technology along the way.

You likely heard how everything can be represented by 0s and 1s. Internally, computers process all information as binary numerals - expressions using only 0 and 1. For instance, the binary 00, 01, 10 and 11 correspond to the decimal values 0, 1, 2 and 3. 

Why restrict to 0 and 1? Because electrical signals can only input and output those. More accurately, 0 and 1 are abstractions for humans. The system recognizes high/low voltage differentials as ON/OFF states instead. For example, 5V = ON, 0V = OFF. 

The IT Engineer Debugging in Another World

The day after arriving in the magical city, we started an investigation to confirm the truth about the rumors of something strange happening in the city.

The basics of an investigation is gathering information by asking around. Lettie actively called out to passersby and townspeople, asking if they had heard of the rumors.

"I ain't never heard of such rumors, no sir~"

"People disappearing? Can't say I know anything about that... Though sometimes I do wish the wife would disappear."

"You wanna disappear, boy? Fufu, with a meek face like that you're no good... Alright, big bro here will take you to a nice place!"

The investigation was not going well. Other than the creepy big bro who tried to abduct Lettie, everything seems peaceful.

The city gives an impression of abundance, with convenient magical tools everywhere, and seems very livable.
