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?"

Because of the fight for the magic treasure, the time traveler, the demon cultivator Logan, was beaten to death, but he was reborn in the wizard world with the magic treasure "Origin Pearl", and became a humble horse slave.

The wizard world has weak spiritual energy, but fortunately Logan has the origin magic pearl.

Magic Pearl: Only by sacrificing the origin of living things can you exchange for the inheritance of the previous life's magic sect- weak spiritual energy?

Then use the evil spirit as nourishment! Practice the art of attracting evil spirits and nourish my demon body.

The means of protecting the way require spiritual energy? Then refine the ghouls to protect me!

The undead wizard in front, don't leave, enter my Ten Thousand Souls Banner for a chat!

Watch Logan use the materials and rules of the wizard world as firewood to ignite the fire of magic:

corpse refining + undead = soul-binding battle puppet

magic array + barrier science = soul-devouring magic net

poison pill + alchemy = rule poison
