Journey doesn't start until I had petted enough

Wei Guiyin woke up and the first thing she saw was an immense space that extended to what if seemed like infinity. There was one word that came to her mind when she saw it, shit.

She was pretty sure of what was happening right now. She was not like those MC's that even though they appear intelligent they always ask the same question. For a second she thought that she might be dreaming, so she pinched her tight, but it hurt, so this was the reality.

[Welcome host to the 'Destruction World System', and I was lucky since there has never been one before, so I have the number 001. It is all thanks to Host.]

When she was waiting for the predictable to happen a mixture of mechanical and childish voice was heard inside the space. Wei Guiyin turned to look at the origin of the voice and it turned out to be a small 'cat'. It had shiny white fur, and as a cat lover, the first thing Wei Guiyin did was to pick up the 'cat' and began to scratch the bottom of its jaw.

[Host what are you...ah..there..purrrrr a no wait Host I need to ahhh it feels so good. Do it more~] At some point the system gave up to the pleasure of being petted by its host.

It was not until several hours passed until Wei Guiyin was satisfied that she stopped did she let the already tired 'cat' go.

[huff..ho..host let me explain to you where you are] The 'cat' was totally exhausted so its voice came out by parts.

"No need, I already know where I am and why I am here." When he wanted to fulfill his role as a system it has ruthlessly stopped.

[Eh, but how do you know? I have not told you anything] As the 'cat' asked the question, it's head hanging to one side, and that little action caused it to be under another round of petting.

It was not until another couple of hours passed that Wei Guiyin let it go again.

[Ho...Host at...least...let me explain to you what is your mission]

"Is isn't it to destroy worlds?" Again Wei Guiyin ruthlessly stopped the 'cat'.

{why do I out of sudden had the urge to cry?}

[Yes host, that is your mission, do you want to go to your first world now?] The system now pet cat gave up trying and just gave in.

"Later, let me pet you a little more"
