The Shen family in the south of the Yangtze River was wiped out. Shen Qingci, the only survivor, fled to the Nanshan Mountains carrying a family heirloom jade pendant. He met the mysterious man in blue, Su Wuji, by a cold pond. One is an orphan girl from a famous family who is burdened with a blood feud, and her sword is like a broken shadow hiding its edge; the other is a former palace guard who was falsely accused of killing his master, and his iron sword has no scabbard to hide his past. The two were bound by a common enemy. They practiced sword fighting to protect each other from Zhongnan Mountain, went to Tingxue Tower in Jiangnan to explore the conspiracy, and then broke into the secret hall of the capital to track down the inner ghost. They stepped on the tip of the sword every step of the way.
The shadow guards of the imperial court are chasing after them, the betrayal of the top secret cabinet officials is caught off guard, and the secret of the "Mountain and River Map" draws them into a bigger whirlpool. Several assassinations, defections of confidants, and life-and-death decisions made them see clearly the treacherous nature of people's hearts in the blood and fire, but also made each other's beliefs stronger - even if the world is an enemy, they must protect each other and avenge the dead.
When the conspiracy was finally solved and the enemy was killed, the two green swords that had been stained with blood finally put away their sharp edges. They bid farewell to the turmoil of the world and sought a place of green mountains and green waters to retreat to, leaving only a legend about loyalty, redemption, and sincerity that echoed gently through the years.
