transmigrate into a merman in apocalypse world

I was walking through a bridge when I was hit by a man riding a motorcycle throwing me into the river. And just like that, I died leaving my sweet kitty Mimo at home hungry. And so I drift away as I lose my consciousness

....

"huh. where am I?"I open my eyes still in a daze. I then realize I'm underwater. I'm still alive!!

No something is wrong. Why can I breathe? And how is it possible to survive underwater this whole time? So what s could be happening?!

I finally know the answer. Just look at the fishtail attached to my waist. I turned unto a fish!! I'm getting too much of a chock that I couldn't handle. First, let's breathe. Second, let's think positively at least I'm alive right. Third deal with reality. Checking my body thoroughly. I can summarize my situation in this way "I got reincarnated into a new body. A merman's to be exact. But I still don't think that I got reincarnated this body is although fair and young it's not newborn. If I'm not wrong my soul took over this body and probably as what happens in the novels. The original must've died.

If only there was a mirror to see my appearance. I wish that I don't look like a monster.

Staying here won't help an anyway let's look around. My movements were jerky and my speed was slow but that is what to expect of someone who just turned into a mermaid. The water was greenish contradictory to what an ocean looks like. Am I in a lake? It should be. I'm tired let's find somewhere to sleep.

Ping' suddenly I hear a ring buzzing in my head

"welcome host to the world number X4433. This world is under the threat of zombies. Mutated creatures and other unknown threats. I'll be leaving some benefits for you before shutting down. Once you obtain the required energy I'll automatically light up. Take care and stay alive"

Huh? System? Are you still here??

No one answers. And I felt more like I was abandoned by it.

What should I do? How can a fish survive the apocalypse and what are my benefits??

I forgot to list the benefits. You are now able to purify any kind of impurities.

Your tears turn into pearls once eaten by any other creature than you it will make his body stronger and prolong his life. Absorb energy while dispelling the impurities. It can also expel hunger for a time duration.

You get to turn 4 kinds of fish into mermaids although not as pure as you. They are loyal and each can get special abilities.

The longer your hair is. The longer the area you can communicate and observe gets

The last ability is secret. You can only figure it yourself.

Farewell.

I have a bad feeling about this.

Putting that aside. Except for getting myself subordinates. Doesn't all my other ones make me cannon fodder?

Grrrl I'm hungry. What can I find in here?? I don't know how to fish or hunt. Right, I can make my subordinates do it. The first step is to look for fish. But until now I didn't pass one. Did the fish also turn zombie?

I've been swimming for 2 hours. And I can't find any. Forget about having a subordinate I don't see anything to eat. At this rate, I'm gonna die all alone. he felt helpless and fearful and so started crying and weeping like a kid.

I wanna go home. Mermaid is no longer fun. What's the point of being one if you can't live in beautiful waters. Wahhwaaaah

Tears fell from his eyes one after the other. Turning unto pearls and falling to the bottom of the sea.

The bottom of the sea suddenly started shining. Turning the green waters unto blue clean. After a while, a bunch of fish swarmed towards him. disfigured and blackfish with sharp teets turned unto their beautiful original look.

he finally stops crying, looking at all the fish surrounding him he cries "you finally came out !! they must've heard my grief and came to cheer me up, good fish!! which one should I choose?" my sight suddenly caught a lionfish.

"awesome!!" Lionfish are carnivores and have venomous spines that can be very painful, once it becomes my subordinate it can help protect me" I choose the lionfish"

the fish abruptly emits a gleaming light that turned into a humanoid figure with a long tail.

" he doesn't look like what I expected" why is he slim? the only lion-like is his brown pointy hair.

the mermaid sustained its original fishtail characteristics with the long fins behind its back. after finishing reminiscing about it I realized that the man was starring at me as if waiting for my acknowledgment.

"Hello ?" no one answered so I ask " do you understand me?"

" I can "

"then why don't you answer"

"because I don't know what to answer that with" his answer really made me speechless, and now that he said it fish and humans culture is different "

"master, it's not that it's different but that fish don't have one, most fish's memory span of only 30 seconds and others don't have a conscience including me I only just obtained mine, right !! i forgot to tell you, the sea's water is polluted by some kind of poison that changes the marine life into an aggressive one, I want to thank you for saving me and the others, is there a way for you to save the sea "he was excited that he blurted everything in one breath, his eyes were gleaming with the expectation that I was reluctant to disappoint him."

"I don't know how I did it or if I have the capability to but I'll try my best, after all, I live here" I'm half fish where am I supposed to live if not here, I'll just have to deal with it besides I have golden fingers !!"
