Little Immortal Venerable of the Three Realms

She was a young prodigy of the immortal realm, but after being reborn, she somehow became a blade of grass in the demon realm?! Lan Feifei, the treasured darling of the Lan family in the immortal realm, was exceptionally gifted, sweet, and adorable. But at the age of three hundred, during the “Apocalypse Ceremony,” a demonic seed was discovered inside her. In an instant, she went from being everyone’s beloved to a fugitive wanted across all three realms. Her parents died protecting her, and the Immortal Emperor struck her down into the Demonic Abyss. Her immortal body was destroyed, and her soul drifted aimlessly...

When she awoke, she discovered she had been reborn

But she wasn’t human or immortal, and wasn’t even a proper member of the demon race... She was a Blue Spirit Grass that had only just taken human form!

This spirit grass was famous across the three realms for being utterly useless in a fight. It could do little besides glow and act cute, and was usually kept as an ornamental plant by powerful figures in the demon realm...

However

She unexpectedly discovered that she could absorb spiritual energy from the immortal, demon, and underworld realms, growing stronger with every passing day!

The young lord of the demon realm passed by, but instead of cooking her into soup, he took her in and raised her?

The underworld prince sneaked over to rub her leaves and even watered her with a spirit spring?

Lan Feifei, a blade of grass, is now doing her best to wave her little leaves as she’s pampered by the powerful figures of all three realms... and secretly cultivates immortality.
