Fate is weird. Of all the people in the world, why would it select me to send to a different world?

And what is it trying to do? Put up a show by giving me a system? But oh well, what do I care.

The previous owner of this body was a cripple and looked down on, but now I can slap their faces with my system.

Young masters? Get out of my way!

Princes? Geniuses? Oh please. I have a system. That does not mean anything to me.

I know that I am not the greatest. But fate gave me a cheat system, and I am not wasting it.

I am going to do whatever it takes to conquer this world. Fate forced me to do this. It isn’t my fault if I cause some ruin on the way.

What the hell is this? What the hell happened here?

How did my room become so ruined after a single night?

The floor and table were covered in dust, his new poster of Zhang Liang Ying that had just been posted on the wall a few days ago had already become yellow and tattered all over. Even Zhang Liang Ying’s beautiful face became monstrous, as if an old devil was looking at him with a terrifying smile.

The walls were covered by a mist of cobwebs and the fruits placed on top of the coffee table were withered and rotted to the point that the mold on them had turned black. The fruits below even seemed to have turned into mush. The aluminium framed window that the landlord had just installed not that long ago was now covered in a layer of white ash and the glass was filled with cracks and covered in dust.

The computer beside his bed was also covered by cobwebs and was accompanied by an empty water glass with a withered worm inside of it.

Dust filled the air making Wei Xiao Bei choke as he tried to breathe.

Everything seemed to be ash gray without any light, as if looking at television static.

After just one night, it seemed like everything in the room had aged for centuries or even millennia.

Mother… is this a dream?

This must be a dream!
