Just then, a swordsman wearing blue clothes and a cloak passed by. After watching her practice swordsmanship by the river for a while, he spoke:
"Practicing swordsmanship requires focus. If you're only doing it to vent your emotions, you shouldn't use a sword."
Afterwards, the swordsman pointed out some essential swordsmanship techniques to Nie Susu, and within a few words, she greatly benefited.
Later, the swordsman instructed her altogether for three days before leaving gracefully.
To twelve-year-old Nie Susu, this swordsman was mysterious, powerful, appearing and disappearing without a trace, leaving in mid-air before her eyes, just like an immortal from the novels!
So Nie Susu addressed her as Immortal Sister.
Her progress in swordsmanship was taught by that mysterious master.
Her swordsmanship foundation, however, was laid by this Immortal Sister.
