In his previous life, he was his father Zhou Ping'an who died of illness; in this life, he is the prince Xuanyuan Ping who has "no spiritual roots".
Until he rescued a dying little girl named Ouyang Qiuyan whose spiritual roots were dug out under the cliff.
Their eyes met, and their souls trembled: those were the eyes of his daughter in his previous life.
In this life, he holds the sword as both a father and a teacher. She uses her heart as her sword and Nirvana as her path.
Dynasty conspiracy? Break it with one sword. Sect oppression? One sword leveled everything.
The imperial master wants to seize his sword body, and the noble family wants to refine her bloodline.
He said: "In this life, my sword is only to protect you."
She said: "In this life, I will protect you."
[Double life + father and daughter cultivating immortals + two-way protection + invincible swordsmanship]
