A Former Engineer Entered the Stone Age Unarmed and Built Metallurgy, an Army, and an Empire!

A civil engineer dies in an accident and wakes up among primitive people who fear thunderstorms, wild animals, and neighboring tribes. He has no technology, magic, or ready-made tools—only his memory and experience. He begins by building a stone oven, firing clay, and searching for ore. Gradually, bronze, iron, fortifications, irrigation, and disciplined troops emerge. His goal is not simply to survive, but to build the first empire in the history of this world. ~ Channel Tags Manhwa, Anime, Recap, Protagonist has demonic powers, Manhwa where the protagonist is a monster, Manhwa Summary, Manhwa Recap, Recap Manhwa, Anime Recap, Manhwa Recommendation, Reincarnation, Isekai, Virtual Reality, Overpowered Protagonist, Protagonist OP, Anime Summary, Animated Manhwa, Manga, Manhua, Shounen, Everyday Life, Fantasy, Supernatural, Humor, Magic, Harem, School, Fiction, Revenge Manhuas, Protagonist became a god #manhwa #anime #manga #MANHUA #recap #summary #donguaс
