March 12th, heavy rain. I've traveled to a magical land in another world, only to awaken a "Happy Farm Story System." Give up! I want to learn magic, swordsmanship, and conquer the world. This thing only teaches me to plant trees. What's the point? March 18th, sunny. The housekeeper suspects I'm secretly raising vampires, but the trees are eating too fast. Where can I find enough fertilizer? April 3rd, sunny. I've finally dealt with those Vatican gangs. The system gave me another crow chick. It looks cute, but... why does it have three eyes? ... Years later, Zhang Ling, leaning on a rusty hoe, gazed at the decaying giant trees that obscured the sky. Flocks of deathbirds wrote doomsday prophecies in the clouds with blood-curdling feathers. The mountainous Dusk Wolf trampled the Holy Mountain of the Vatican into a basin. A canopy of jellyfish with baby faces rose from the sea. Behind him, a silver-haired, fox-eared girl...

Humans kneel down to worship corpses, gods rot and whisper, and wizards search for the secrets of decay in madness.

Edward opened his eyes and became an apprentice candidate in the dark wizard world.

However, his low mental qualifications caused him to be deported from the wizard academy in less than 3 months.

Fortunately, Edward awakened the [Disorder Detection Technique] that can dig out hidden information, which made him notice that the mushrooms in this world have unlimited evolutionary potential:

from [mycosac weapons] lurking under the skin to [mycosac horn] parasitic on living bodies;

from [zombie spores] that control insects and ants to [mycotic chimera ants] that absorb high-quality genes from the body;

from [rotten feast fungi clusters] that grow infinitely by absorbing nutrients from corpses to [scarlet corruption] that corrupts and infects all existence;

many years later, Edward, who is known as the [Mushroom Duke], looked at the latest experimental [green-skinned orcs] and couldn't help but fall into deep thought:

"No, what are these fungi doing over there?"
