Apocalypse: Heart of the Druid

I was reborn the day before the end, and seized the heart of the only druid in the world. Plants listen to my orders, and life is given by me - teammates can gain the power of nature, and traitors will have all their cultivation levels instantly taken back. When I rebuilt civilization in the name of "Oasis", the alien telepathic army tore the sky apart. After the disastrous defeat, I fled to the stars, bought a slave army stronger than myself on the black market of the universe, and fought back to Earth. It wasn't until I joined the highest interstellar organization and started working as a cleaner that I understood: The true power of Druidry is to make the entire universe become my garden.
