How the Hacker coped in the Fantasy World

Warning (?) : A bit of violence and cursing. Will have No HAREM even if I'm threatened at gun point. Romance for my beloved MC has never crossed my mind, sorry. World building, family bonds, military and Hacking tactics, yes, and lots of them! *** One wrong judgment can be a one-way ticket to hell. I was Exhibit A. In a single day, my life turned for the worse. The good thing is, it's not just for me. During the worst days, the world as I knew it was also turned upside down several times over. The Abyss—the Gate to the Otherworld—turned the technologically advanced world of Lohiya into a world on the brink of extinction. Not to mention several states vanishing off the map, there was the advent of creatures and races that had only existed in fantasy stories, and they unfortunately went for the neck of every human they set their sights on. Time passed, and in another single day, my life was endangered. Yet on that same day I was also given a chance at redemption. From every misfortune starting with that wrong judgment The bad thing is that it's not just for me. It was a high-risk, high-return deal, with numerous sleepless nights forecasted in between. "But what can a hacker do in a fantasy world?" Redemption was offered in exchange for my assistance in saving worlds, with an emphasis on the plurality. "Damn it all, why not?" I confidently smiled in front of the mirror, gazing at my new identity. "Let's start by building a computer." It was always the best choice to utilize your own strengths. But boy, it was easier said than done. *** I'll be back after some revisions!
