Death of other rats hardly affecter her because Yuriko knew, unlike her, those are lab rats are just animals, but she wanted them to survive. Maybe she just wanted to see, she not only one.

*Day 4*

'I don't even know anymore.'

Yuriko shook her head as she saw blueprints hanged on the room wall. The only thing she recognizes was numbers and shapes as for words she could only call them, a random jumble of symbols.

The whole thing looked very weird as looking around the room, she found one or two guns, but at the same time, she also found things look quite similar to staff, magic staff to be specific.

After the experiment, she found her last partner able to survive while there is only one survivor on the side of group B. As for group C, there was no change just like usual they eat then sleep.

*Day 5*

'This is bad, why is he giving us this much ?'

Looking at quite an amount of food in front of her, Yuriko got a bad feeling. Then a statement from the doctor confirmed her weird feeling.

"It seems like you two, gonna have to do your colleagues part. Aren't you happy if the one you die then another one will receive other's share as well."

'My ass!' Yuriko retorted to the doc. Even someone like her, who possesses only surface knowledge knows getting injected by more than one drug in one day is wrong.

Now knowing the hell waiting for her, Yuriko looked towards her food and only thought she had was.

'I need to eat.'

Because she knew her previous way only work it cause it only happens one time only more than will make it only worse.

Analyzation of an unknown drug reached 50%.

On that night with system sound ringing in her head, Yuriko laid on her, back staring at the roof in a cage beside her laid dead rat with blood leaking out from its eyes and mouth. Even now, she felt something clawing inside of her stomach.

'I miss you brother.'

Yuriko signed as remembering the days were her bother nursed her wherever she got hurt. Especially at this moment, she missed her brother's warm hand and delicious soup he prepared for her.

A special condition met for lesser mutation.

Ignoring the system's message, Yuriko went to sleep.

*Day 6*

After waking up, the first thing Yuriko has done was to check the change that happened in her body.

Stomache Bag An pseudo stomach places right in between the main stomach and liver. The main function is the store half of processed food

After reading the description at first, Yuriko didn't understand its purpose and how to use it. But while eating her meal, she got a hunch of it as she felt like she can control where the food is going. With that, at least she doesn't have to feel empty after the experiment.

Analyzation of an unknown drug reached 75%.

*Day 7*

In that night, Yuriko heard familiar system sound in her head.

Drug analyzation is complete. The system found components used in drug and effect is 90% similar to 'Clear eyes' secret medicine of Shoshannah kingdom.

Received 30 mutation points.

"Skill acquired: Drug Compatibility Increase the effect of any drug while decreasing the side effects

'Shoshannah kingdom? Mutation points ?'

Apologize host, but the system posses information only related to Bio and Beastiary. As for mutation points is a reward for host discovery and absorbing new trait or mutation. A host can use those points for forced mutation or evolution for currently possessed organs

After receiving the explanation, Yuriko opened the menu but only found useless or weird mutations that she can only buy. But seeing many weird mutations, that her organs can turn into she thought.

'Maybe it could...'

Curiosity grew inside her.

*Day 10*

A special condition met for great mutation Mutated pituitary gland: Host's pituitary gland now can automatically produce Clear eyes depending situation

'Am I, suppose to be happy ?'

Seeing weird change happening in her body Yuriko doesn't know she supposes to be happy or sad.

*Day 11*

Morning.

"Hello, subject A5."

"SQUEAK!!"/Asfdsg@!! By the green goddess what the heck!/

Seeing a big red eye with a creepy smile on the moment she opened her eyes, Yuriko couldn't help but startle.

"Hahaha, where is your poker face now?"

Pleased by rat's reaction doctor White couldn't help but laugh as remembering how this didn't show any reaction.

"Squeak! squeak!"/What is so funny about startling people!/

"Okay, Okay, A5, I stop. I got good news for you. Thanks to you, I was able to complete project A so this is my gift. From today you will be enter group B that means you little pig will get all food worth of 10. "

Yuriko saw following his word, doctor connecting a feeder to her cage.

"Squeak!"/If you happy then why you wanted to kill me more?/

With feeder, she can now eat and drink wherever she wishes but she was only a little bit happy because she knows from today, she will get injected with another kind of drug.

'Good news? Good news only for you!'
