I Was Parasitized by a Monster [Infinite Nonhumans]

/Nonhuman parasite/Will begin with 100,000 words in reserve

/Worldbuilding may undergo major revisions, but the core concept will remain unchanged

Mu Chu is an ordinary college student who transmigrates into the extraordinary world of a book, becoming the vicious female supporting character who meets a tragic end.

In this world, those who can summon and form contracts with spirits are revered. There are nine dimensional worlds.

The zero-dimensional world where she lives is a barren wasteland, the most resource-poor of all: the Red Ruins Realm.

The first thing Mu Chu does after opening her eyes is fight through her splitting headache and carry the female protagonist back, after the original owner left her in a graveyard.

But halfway there, she slips and bangs her head against the coffin lid of an unmarked grave...

Everyone tells her to break the contract. But when she sees the hideous, lowest-rank demon spirit stumbling back with a little wildflower for her, Mu Chu wipes her face.

And this Demon God's secret was...

Severely wounded, it returned to chaos. While its mind was clouded, a small world summoned it as a demon spirit, and it became a parasite inside the body of a human girl.

It once blazed a trail through every obstacle for her, and it once died for her.

That day, the little girl clutched its dissolving demon spirit and wept until the sky and earth seemed to darken.

Tch. Raising humans is such a pain.

Why are you crying? Once I fight my way back, the male lead, the female lead, the male supporting characters, the villains... I'll let you walk all over them.

Reader's guide:

1. A strong female lead's cultivation journey, with an original progression system. The multidimensional worlds include wastelands, steampunk, xianxia, and more, with a Lovecraftian flavor, though the main setting is still fantasy.

2. The romance develops slowly, with the two raising each other. The progression plot is the main focus.

3. Yuan is neither human nor a contracted demon spirit, but a different species, like an alien from beyond the heavens. Its true form is like the cover; its human form has pure black skin and white hair (cont...

4. Yuan is a member of Jie, the male lead in another novel, The Rules for Loving an Alien Monster. This is a completely independent story, though this novel is a spin-off in the same series.
