Possessed by a Ghost? Sorry, My Cancer Cells Are Hungrier

With terminal cancer and only three days left to live, I was forcibly invaded by an S-rank Skinwalker, which planned to possess my body.

I thought I was done for. But the moment it got inside, it let out a shriek of utter despair.

It discovered, to its horror, that the hyper-aggressive cancer cells multiplying inside me were all indescribable monsters! It was treated like a targeted drug and devoured alive!

While others desperately flee from deadly rule-based horror games, I exploit my cancer cells’ “infinite division” to freeze the rules with a bug;

while others are scared witless by S-rank evil spirit domains, I prick my finger and let a single drop of blood turn the entire terrifying realm into a cancerous version of me!

When eldritch beings from the abyss launch a full-scale invasion and all of humanity falls into despair,

I transform into a flesh-and-blood wall that blots out the sky, and open my abyssal maw:

“Thanks for nature’s bounty. Let’s feast!”
