Fourteen years ago, Pei Rongjing, the first hero of the founding of Daqi, suddenly led his troops away on a snowy night, taking with him his nine-year-old eldest daughter Pei Xian. Pei Rongjing became a rebel and wandered in the border desert. Within a few years, Pei's army was wiped out in a battle with the foreign Qi Gu. Only Pei Xian was saved by the then Qi Gu military advisor Shen Qingye during the battle. As a result, Pei Xian owed his life.
After recovering from his injury, Pei Xian changed his name and joined the land of Qilin, known as "Qilin Ink Masters all over the world, and Qilin Pavilions everywhere" to cultivate his skills secretly. Unexpectedly, Shen Qingye suddenly came one day and wanted to get back the favor he had received many years ago - to return to Daqi as his wife. Pei Xian readily agreed.
At that time, the Daqi warlords were separatist, and the imperial power had long been controlled by Chun Yuchi, one of the three heroes of the founding of the country, "Otsuka Zai". As a result, Pei Xian, or Qin Guiyin, embarked on the road of revenge and return filled with grudges and love.
