In a stone room of an ancient tomb on the snow-capped Zhongnan Mountain.
A middle-aged woman with a delicate face pointed to a portrait on the wall and said to the lovely girl Yuxue beside her: "This is your master. She left a legacy. All my disciples are not allowed to take a step down Zhongnan Mountain. Mo Chou, can you do it?"
The girl thought for a moment, then asked instead: "Master, if you practice your martial arts to a deep level, can you become an immortal?"
The middle-aged woman shook her head and said: "Prolonging life is possible, but becoming an immortal is not possible."
The girl asked again: "Can we divide rivers and seas, split mountains and earth, go in and out of the dark world, and reach for the stars and the moon?"
The middle-aged woman paused and said, "No."
The girl said categorically: "Then one day I will definitely go down the mountain. Even if I travel to the ends of the world, I still want to find immortality."
