General Zhenbei Ying Wulan has recently won a battle and returned triumphantly to the capital, only to learn that the Emperor is suffering from a strange and difficult-to-treat illness. He and the current Emperor have known each other for twelve years and were fellow disciples. He immediately resolves to find a physician and medicine. But although his heart is set on the Emperor's health and easing the burden on his sovereign, the Emperor grows suspicious of him because of his true identity.
Ying Wulan only wants to drive back the Xiongnu and reclaim lost territory, bringing peace to the people. He has never harbored treasonous intentions. But serving the Emperor is like walking beside a tiger. With such a sensitive identity, how can he earn Ling Huanjun's trust?
The kingdom is in turmoil, his family's vendetta remains unsettled, and the Xiongnu beyond the frontier are watching like tigers, their reach already extending a thousand li to Yanjing. Stripped of his military command, Ying Wulan has no choice but to seek a solution from Princess Huiyun, Su Qingzhi. And as if things weren't bad enough, Xiongnu spies have set their sights on him...
See how the Emperor and the general stand firm in a turbulent age, and rebuild a peaceful and prosperous realm.
