I Awakened a Pen from the Start. How Am I Supposed to Play This?

Everyone else's abilities involve space, time, spraying water, breathing fire, moving mountains, or filling seas.

But Bai Xiu's ability is a pen? How is he supposed to use that?

Am I meant to show people how to write or draw with it?

Luckily, Bai Xiu discovered what the pen could really do: anything he drew could become reality!

Bai Xiu: As a descendant of the dragon, surely there's nothing wrong with drawing one.
