Following the robotic voice, a large blue screen separated into two parts appeared in front of her.

Name: Yuriko Age: 1 year Species: Test Rat Current State: Somewhat strong rat.

Skills: Martial Mastery(Unique), Apex(Unique)

Traits and Mutation Trait: Toxin resistance, Strong Teeth, Strong Jaw Mutation: Double Joint

'It even followed me there.'

Yuriko had nothing to say as skill description reads, it allows her to learn and master any combat. As for apex, it allows her to absorb other living things physical traits into her body and even mix it with others to create an even stronger one help her to evolve further.

Closing the screen, she saw an old man that suspicious person called White observing her and other rats with a smile while rubbing his palm.

"Well hello, my precious test subjects, my name is Doctor White, you all will become my step into immortality."

'Introducing himself to rats and talking about immortality he already past insanity this old man is a goner.' After hearing an old man, Yuriko reached a conclusion.

"Now, let's quickly start!"

Said White reached his hand to pocket of his coat and pulled out stacks of sheet paper with letters then begins to place on each cage.

"You five for project A, those five for project B and last those ten for project C. Just wait and see Zera, I will surpass you!"

While man placing the letters, Yuriko able to saw her letter right before the doctor place above her cage. It was the letter /A/ from paper's wrinkled dirty edge it showed this paper, used many times previously.

"Here, eat those."

After finished placing the letters, an old man gave her something to eat and other rats before leaving the room.

*Squek?*/What are those ?/

Yuriko inspected the food that the old man gave her, it was something similar to bread crumbs mixed with nuts, but upon closer look, she noticed those crumbs and nuts are covered with unknown powder.

Stolen from its original source, this story is not meant to be on Amazon; report any sightings.

Even with a sniff, she doesn't smell anything but crumb and nuts, but it was clear that the mad doctor covered them with something. Looking around, Yuriko saw other rats just eating them without any suspicion.

'Being an animal must be nice without worry about anything.'

As for herself, she couldn't touch that suspicious food even though her stomach growling and asking for food. On the edge of her cage, Yuriko just stared at food while shivering from a cold breeze with an empty stomach.

'I am gonna starved to death ?'

She doesn't know how long she stared at that food, but word death ringed in her mind. Will she die in this unknown laboratory as a rat?

Someone will miss her? No.

She had a friend? No.

What is her life goal?

Nothing, except torturing that woman, but now she can't.

Maybe it would be alright to die like this, without being experimented on. Seconds passed, minutes passed, hours passed then in a moment she realized she is gobbling up those like there is no tomorrow.

'So I wanted to live after all. I don't care those are poisoned or not!'

She felt those bread crumbs and nuts, even more, tastier than restaurant food. After finished eating all of them, Yuriko went to sleep with a full belly.

System found a substance that provides benefit to the host's growth adding to the database

"Yes, all of you alive!"

Woken up by White's word Yuriko opened her eyes and saw a man pacing three boxes in front of each cage with cores holding letters. From box with a letter, C man took out two small red marbles and gently placed them before each cage.

From A and B box, he took out a syringe needle with a small bag attached behind it. Each bag had a red and green label then man proceeded to prick B group with a syringe with a green label and group A with the red one.

With a gentle squeeze on the bag, Yuriko felt some kind thing entering her bloodstream.

Warning system detected unknown drug in the host's blood. Analyzing 10%.

Yuriko doesn't know anything know what kind of thing inserted but suddenly she felt more relaxed at the same time she felt her mind clearer than even as if someone erases any of needless thoughts.

At that moment, she noticed a doctor's unusual one red eye and schematic of a gun placed on the lab's wall along with other unusual plants and animals. Then she saw a doctor carrying her group into another room.

"Okay, starting test A90."

'Okay, so you starting the test.'

Said the doctor leaves, Yuriko along with a cage on the ground. Looking around she found she is been surrounded by many street cats looking her with hunger while doctor observing her thought glass window on the door.

Despite being stared down by many hungry cats, Yuriko felt didn't thing as if emotion called fear completely disappeared from her mind. Eventually couldn't hold much long from hunger, cats have begun to claw her cage with their sharp claws and tried to take out delicious food layin inside.

Yuriko knew if she moves a little bit in any direction she will be ripped apart alive, but she didn't feel anything as she stood in the middle of the cage. Feeling a bit bored from constant shaking she began to count whiskers of cats around her.

'One, two, three, four, five, everybody in a car let'ss!? what... FUCK!'

Suddenly realizing where the rest of her brain went Yuriko couldn't help but curse this catchy song.
