Only finding what you spend your passion, knowledge, time already exists in word only, you just helped them to create that, Yuriko don't know-how is that feel because of she is the one who let somebody feel that way but doesn't mean she doesn't feel anything.

Because she saw how her brother felt after being constantly beaten by that by a girl one year younger than him and being called pathetic or weakling by others who don't know how many things he sacrificed.

Every week he walks in home beaten and hurt from the match. Saying he is alright, nothing to worry about with a false smile while like an idiot, she believes that fake smile without realizing how much he enduring.

So just for this night, Yuriko decided to forget what this crazy doctor has done to her and comfort him.

To tell the truth, she was not even that angry at the doctor because will she pity the animal that created for the single goal of being tested if she was in the position of a doctor?

The answer was no.

'This is has a nice feeling.'

White thought A5's fur felt soft, silky, warm.

"Thanks, A5."

Said doctor leaves the walks out room with a slight smile.

Seeing the doctor leaving the room, Yuriko moved to the back of her cage and removed some dried plants revealing a small hole about the size of her head. But she just made this hole for just in case scenario. Why should she leave when everything she needs is in this room.

She can eat and drink her full while dust mixed with food will enhance her body and increase her evolution. Thanks to the doctor's experiment, she enhances her organ or mutating them, earning mutation points. She only left her cage cause she wanted to eat more mineral and iron.

Moving around the table, Yuriko found a few more things made of steel and copper like a candle holder, broken doorknob.

'Why all man I met don't clear their table? Is it just me by some chance encounter ones or just men's themselves ?'

Yuriko was happy that she found a thing to eat, but at the same, she couldn't help but point out how dirty this table is. While searching for another thing to eat, she noticed rats in group C haven't moved for a while.

'Weird usually they would be moving around their cage.'

With a thought, she moved closer to one of the cages and saw rat laying there without any sign of movement.

The story has been illicitly taken; should you find it on Amazon, report the infringement.

'What the!'

Suddenly she saw a small shadow jumped towards her. Taken by surprise Yuriko immediately tried to dodge away from that thing, but she was a little late. She saw the thing immediately burrowing into her body in quick faster than she moves her claw.

Feeling something unknown burying into beneath her skin, she felt incredible fear. Then a moment later, she heard the system's message.

Blood Centipede successfully captured and consumed by Terrus parasite. The host received 20 mutation points.

Host, have some confidence with Terrus parasite inside your body, you don't have to worry about any other parasite invading your body. Especially about this kind of parasite bugs like Blood Centipede.

After hearing the host's message, Yuriko really wanted to kiss her new friend for protecting her body. She doesn't know what other things do, but having a strong guard in exchange for something like she doesn't even know it missed or not was completely okay.

Yuriko was incredibly happy swinging her naked tail to the left and right, knowing thanks to her little pal and knowing the points it gives. She quickly turned the other nine into mutation points.

From on looker's point of view, it looked bizarre as seeing a disgusting looking centipedes jimping from cage to a large white rat looks like white puffball that passing each cage while shaking her ass in a good mood while not showing the slightest reaction.

After finished turning centipedes into points, Yuriko went back to her cage, along with things she found. Then she spends night eating those things.

Strenght: 7.3 Agility: 12.1 Intelligence: 8.1 Dexterity: 7.5 Contitution: 12.1 Evolution: 15/40"

*Tomorrow*

"Again, it failed."

Doctor White took a deep sigh seeing a ten dead rat laying inside the cages. He knows the chance is closer to 100% but still disappointed.

"Next batch will arrive after two weeks. Now I gotta distribute finished drugs to volunteers."

Taking his medical bag, Doctor White walked towards the door suddenly a something white flashed his vision. Quickly moving his head noticed A5 looking towards him with its big bead-like eyes.

Seeing its sitting in the cage alone, Doctor White felt bad leaving her alone.

'It is just her reward.'

Justifying his reason, Doctor White decided to take the A5 alongside with him. Rising the cage, White felt A5 gotter even bigger and heavier than last time. He thought it is because of its diet that he mixed with low-grade crystal dust.

"Wow, you got quite heavy."

"Squeak!/I am not heavy just big boned! You fish head!/"

Suddenly hearing the insult from a man who can't even shave properly Yuriki immediately fired back but sadly doctor didn't know rat language.

"Heavy is heavy. Be grateful A5 you're first test rat that leaves the lab."

Said Doctor White places Yuriko in his bag and leaves his lab.
