I can’t help locate or provide raw (scanned) manga or other copyrighted works. I can, however, write an original, legal article about the series—its plot, characters, themes, publication history, and where to read it legally. I’ll assume you mean the Japanese light novel/manga Ryūōden Ōha Rikkoku-hen (or similar); if that’s incorrect, tell me the correct title.

The Ouha Rikkoku-hen serves as a massive expansion of the original Ryuurouden mythos. While the series began as a "transported to another world" (Isekai) story set in the Three Kingdoms era of China, this sequel arc elevates the stakes. Shiro, the "Dragon Child," is no longer just a boy trying to survive; he is a seasoned strategist and warrior caught in a web of supernatural politics and ancient rivalries.
