Southern Archives: I Dug a System Out of an Underwater Tomb

I transmigrated as Zhang Haiyan, starting out trapped in a desperate situation in an underwater tomb, where Zhang Haixia gave his life to help me escape. Just as I was losing hope, the Infrastructure Maniac System awakened! A warlord in Nanyang wanted me to dig for treasure? I'd build him a military base first! The Zhang family's archives wanted me to investigate a case? I'd turn the entire South China Sea into an intelligence network! When Zhang Haixia returned, gravely wounded, and saw the steel battleships and deep-sea bases I'd built, he was stunned. "Salt Boy, are you turning the South China Sea into our family's own backyard?"
