After the Plot Goes Off Course, I Lie Flat in the Harem

Lin Yiran transmigrates into a novel she has read and becomes Lin Qingran, a cannon-fodder concubine-born daughter.

Her legitimate elder sister is the heroine of the book.

After entering the palace in her sister's place, Lin Qingran discovers that she isn't the only one in the palace who has transmigrated into a book: there are also people who have been reborn and others who have transmigrated...

Contact lenses become her ultimate cheat, giving her a pair of eyes that can see through anything.

With her ability to see the true nature of all things, she obtains a golden finger.

With her golden finger, she cultivates tea plants, makes cotton-padded clothes, and rescues women in ancient times.

Then she embarks on a new career in the ancient world.
