Reincarnated as a Mushroom, the Empress Was Decomposed by Me!

[Reincarnation Mushroom + Rebirth Empress + Species Evolution + Scientific Cultivation] Shi Yi woke up and found that he was reincarnated into a mushroom in the world of immortality. As a lowest-level decomposer, absorbing spiritual energy will only make you more delicious. The arrival of the [Strongest Decomposer System] has paved a path to the ultimate evolution for him! The system lifts the evolutionary restrictions. Knowledge points can be obtained by decomposing organisms. Accumulate knowledge points, improve the level of organisms, and unlock tissues and organs that can only be produced by advanced organisms. As he continued to upgrade, Shi Yi also unlocked more functions: using mycelium to replace the meridians of monks so that disabled people can practice; changing the properties of fungi to batch-produce magic weapons; making simulated golden elixirs to quickly become golden elixir monks; simulating the ascension breath to enter and exit the world of immortals and demons at will... From low-level fungi, evolve step by step until you reach the top of the fairy world... This was the original plan, but a soul broke into the body, claiming to be some kind of empress of the fairy world, and she refused to leave. "It's funny, return the queen, get out of here quickly!" "I won't leave. My body has been broken down by you. I want to practice here." (#`Д´)ﾉ … My name is Yun Jingxin, a strong man who was reborn from the fairy world to the mortal world. In order to return to the fairyland as soon as possible, I came to an ownerless cave and prepared to search for resources. Ah, why did I die again...
