In the midst of various attempts by different parties to intercept the convoy and seize the blades, eventually, through serendipity, the weapons end up in the hands of two couples: Yuan Guannan and Xiao Zhonghui, and Lin Yulong and Ren Feiyan. They are defeated by Zhuo Tianxiong, a highly skilled imperial guard who disguises himself as a blind man and hides in the convoy to protect the blades. The couples are forced to seek refuge in a dilapidated temple while attempting to evade pursuit by Zhuo and his men. Out of desperation, Lin Yulong and Ren Feiyan teach the younger couple, Yuan Guannan and Xiao Zhonghui, a saber movement known as the "Couple's Sabers". The saber movement covers the two partners' weaknesses while multiplying their combat lethality, making them virtually invincible. Yuan and Xiao defeat Zhuo with this new technique.
