Mira is determined to be a botanist—no matter how dangerous or violent it may become. Mira made two requests upon entering the multiverse: a botany class to further her research and to be dropped off in an isolated forest far from the violent god-rearing system BS going on. She was granted both—but not in the way she expected. The system abandoned her in a hellishly dangerous forest—where she earned a rare class that excelled at killing things.

Mortal cultivation, resurgence.

Time and space shuttle, reversal of reincarnation.
Jinxian Taiyi, Da Luo Daozu.
Three thousand avenues, the law of supreme.

“Faculty of Immortal Immortal” is a fairy tale, a story of Han Lizhen’s fairyland, a legend of a mortal kid who cultivates immortals.
