Seisan Skill Wo Kiwameta Ore No Isekai Sozo Harem Life! Jozu Ni Gendai Su Zukuri Dekimashita! (King Novels) [Light Novel]

[Machine Translation] Daigo Ohgami was struck by lightning while returning home, and upon his death, he was transported to another world. There, waiting for him was a kind and supremely attractive older sister, the blonde, big-breasted priestess Terena. She had summoned him after praying to the gods, and her wish was that the technology developed in Daigo's world be passed on to this world as well. It was a happy wish for Daigo, who had always enjoyed making things, and the god had given him the cheat ability to do so. When he tried it, he found that it was a knowledge-based ability that allowed him to view every manufacturing technology on the planet. Moreover, it seemed that the more things I made with that skill, the more I improved it and the more efficient it became. Daigo is amazed at the technology he has never seen before and is always grateful to live with Terena, with whom he bonds and vows to develop this world. Hazumi, a girl from Japan, Philomena, a beautiful dark elf, and Lara, a princess full of curiosity, also gather around him, and before he knows it, Daigo is surrounded by a harem!
