Set against the historical backdrop of the Wanli Emperor's aid to Korea against the Japanese invasion, "Night Scouts of the Great Ming" tells the passionate legend of Li Dagu, a descendant of the Qi family army and an elite night scout. With Korea in critical emergency and Japanese pirates invading on a grand scale, the imperial court resolves to dispatch troops. Li Dagu rejects recruitment by the Brocade Guard, steadfastly maintaining his original aspiration to guard the borders and fend off the enemy. Crossing the river with the southern army, relying on his formidable martial arts and reconnaissance skills, he repeatedly defeats Japanese scouts, burns supplies, bravely captures Moranbong, and infiltrates to blow up the powder magazine, achieving successive great merits in the Pyongyang Campaign and the bloody battle of Pyokjegwan. Combining battlefield combat, espionage infiltration, and national sentiment, the series restores the iron-clad loyalty of the Ming border elite "Night Scouts," composing a soul-stirring epic of resisting Japan and defending the country.
