The good news: Lin Wan has transmigrated.
The bad news: Other people transmigrate and get a divine artifact, a mythical beast, and a god-tier talent all in one go. Lin Wan transmigrates and gets a System, a bug, and a pile of little items that look completely useless.
On her first day after transmigrating, she gets one item: a white towel that never gets dirty.
The System even helpfully labels it: Useless. Truly useless.
Lin Wan: I can't thank you enough. This is basically a death sentence!
System: Transmigration is risky. You accept the consequences. This System accepts no responsibility.
Lin Wan: ...
Fine. I'll make the best of it. But can you explain what that giant dragon in front of me is?!
But... did that seemingly useless white towel just save my life?
Wait, this way of surviving is way too absurd, hey!
System: Host, rest assured. This System believes in absolute fairness and impartiality, so many of the rewards given to you will definitely be useless junk. So do your best to stay alive!
Lin Wan: ...
Is this really what we're worrying about right now?!
