- Description from Novelupdates

Five years ago, Qiao Nian was schemed against by her sister, Qiao Xin. After spending a night with a stranger, Qiao Nian got pregnant. She did not know who the father of the child was, and eventually gave birth to a stillborn. Under the machinations of her mother and sister, Qiao Nian was stripped off of her shares in Qiao Group and sent to a mental hospital.

A tribulation lightning strike allowed her to be reborn with a mutated space. Parents are deceased, but not to worry, she has an agricultural expert grandfather. People bully her, but that's no problem, as she is a cultivator. The space is barren except for a single broken sapling that only consumes precious metals. The sapling indignantly asked: Others eat grass and give milk, what about you? The little immortal sapling spat and said: Here, remember to exchange it for some RMB.
