The sea water was extremely cold.

I swam with all my strength towards the shore.

A sharp pain surged from the soles of my feet.

It wasn't a leg cramp.

A creature resembling a leech was attached to my skin.

It crawled on my leg.

Its speed was incredibly fast.

It burrowed into my body through a passage.

The pain became increasingly intense.

It felt as if a sharp knife was piercing my organs and an electric saw was cutting through my wounds.

The pain was so intense that I almost passed out.

Before losing consciousness,

I heard my mother's voice:

"You're so lucky to parasitize such a young body."

When I regained consciousness,

I was lying in my bedroom at home.

I remembered... Did I go swimming with my mother?

My body was uncontrollable, and I suddenly sat up.

I was thirsty.

I got up.

I picked up a glass of water.

I was drinking water.

Wait!

Why did the water spill?

I took another sip.

The water leaked from my mouth onto my clothes.

What's happening to me?

I rushed to the bathroom.

I was incredibly fast.

I held onto the sink.

I saw my reflection.

"Ah!!!"

I screamed in terror.

In the mirror, I had two heads.

Like a deformed conjoined twin, the back of our heads were connected, with two faces, one on the left and one on the right.

The left face was my original appearance.

The right face had sunken features, wrinkled and horrifying like a withered flower.

I lowered my head.

My fingers became sharp and pointed, like two scythes slicing through iron like mud.

Clang—

The sound of the security door opening.

I turned to look.

My mom and dad had come home.

My mom said, "Xiao Mei! What's wrong with you? Your ghostly appearance will frighten people!"

My dad said, "Take a lesson from both of us. We've already fully assimilated into human society."

My mouth opened uncontrollably, emitting the exact same voice as mine:

"I haven't learned how to control the human body..."

My dad took out pen and paper.

My mom said, "As human beings, there are rules for human life. I'll write them down for you, and you must remember them."

My dad said, "As long as we disguise ourselves well, we can successfully replace humans without ever being discovered."
