Chang'an Is on Fire, Lovesickness Under an Umbrella

The maple leaves in Chang'an turned red and then fell. Li Xin grew up from an ignorant boy to a general holding a sword to protect one side. A Li also went from a little girl following him to a descendant of the Gongsun family who could hold up a red umbrella and dance solo. What was once a joke, "I will protect you", became a tacit oath to each other in the city of Chang'an where the war was raging. He holds a long sword to protect his family and country, and she holds a red umbrella to protect him - when the mountains, rivers and sweetheart are before her eyes, where should Li Xin's sword point? And can A Li's umbrella catch his wind and frost?
