Across Two Ages: The Great Yan Infrastructure That Shaped the World

Mo Zhenshan is an ordinary garrison soldier stationed on the frontier of the Great Yan Empire—diligent, loyal, and deeply compassionate toward the common people. Weary of endless wars and seething at the corruption of local officials, he endures the harsh life of a border sentry. During a routine patrol, he is caught in a once‑in‑a‑century thunderstorm and struck by a freak bolt of lightning. Instead of perishing, he awakens bound to the Eternal Ancient‑Dual‑Realm System, which grants him two supreme talents: absolute photographic memory and the ability to travel unharmed between the ancient past and the present day. Armed with these extraordinary gifts, Mo Zhenshan sets out to reshape his world—not through conquest, but through the transformative power of infrastructure and governance.
