The Unremarkable Little Junior Sister

Ye Mingyan, the junior sister of Xuanyun Sect, has mediocre talent. She can't keep spirit herbs alive, blows up the alchemy room whenever she tries to make pills, and consistently comes in last in the sect's annual assessments. Yet her sect leader and master dote on her, while her senior brothers and sisters indulge her. She's a lazy, useless slacker.

In her tenth year at the sect, Ye Mingyan follows her senior sister into a forbidden area to gather herbs. She is unexpectedly caught in a temporal rift and discovers that she is living inside a book.

According to the plot, the righteous sects will slaughter her sect because of her.

The good news is that Xuanyun Sect won't be destroyed for another hundred years.

On the night she returns from the forbidden area, a cold and aloof Sword Venerable appears in her cave residence, sword in hand, and says indifferently, "Get up and cultivate."

The next night, a red-robed Demon Venerable appears in her cave residence, smiling sinisterly. "Get up and cultivate."

After that, every night, powerful figures from the various sects take turns showing up.

Growing spirit herbs, refining pills, purging pill toxins, cultivating the sword path, forging weapons, cultivating demonic arts... She learns the techniques of both the righteous and demonic paths, one after another.

When Sword Sect disciples come demanding she be handed over, she brandishes a willow branch and unleashes a breathtaking sword intent, taking on ten opponents at once.

When demonic cultivators come calling, she knocks them all the way to the foot of the mountain with a single Brahma Sea Demon Slash.

Everyone: What the hell, she's a healer?!

Everyone in Xuanyun Sect: You might not believe this, but we had no idea our utterly ordinary junior sister was so strong.

The Sword Venerable, the Demon Venerable, and the elders of the various sects: You should ask who taught her.

Everyone: ?!

Theme: To forge iron, you need to be strong yourself.
