[No CP for Now + Cultivation Transmigration + Strong Female Lead] (Content warning: The heroine is still growing, and she won't cultivate in a sect forever. The tags can't be changed, but there may not even be a male lead in the end.)
Cheng Yu transmigrates into a book, specifically The Beloved Darling Ascends to Immortality. Unfortunately, she's not the heroine, just an extremely unfortunate cannon-fodder side character.
Her several senior brothers all dote on Tang Manxue unconditionally.
Later, when Tang Manxue is injured and needs a blood transfusion, that bastard Yin Sheyue ties Cheng Yu up and drains her blood.
In the end, some of them die and others are injured, while Tang Manxue ascends to immortality in all her glory.
"Damn it, let's see if I can't deal with this little green tea!"
Having transmigrated into the book, Cheng Yu swears she'll make sure her senior brothers and sisters stay alive!
Later, when the demon race invades, ordinary people become stepping stones, and the cultivation world suffers heavy casualties...
"With my soul, I will trade for your annihilation. Even if my body and soul perish, I will do so willingly."
