Wu Yu wordlessly picked up the little black notebook and flipped through it. The paper was the same kind he'd always used for his drafts. He hadn't expected Kaguya to be so attentive to detail—or maybe she'd simply shut down every excuse he could use to get out of writing.
"Huh?"
Wu Yu ran his fingers over the black cover and back cover. The texture felt... a little unusual.
Mysterious Kaguya said calmly, "Close the notebook and pour Chakra into it to replace any pages you tear out. Open it and pour Chakra into it to write with your thoughts."
Huh?
I mean... huh?!
Wu Yu gaped again. Did she really have to go this far just to cater to my writing habit?
So now she wasn't worried about wasting Chakra?
"What about these two?"
Wu Yu sat down and placed the little black notebook on his lap. He picked up his usual model of fountain pen with one hand and a small bottle full of ink with the other.
"Pour Chakra into the pen, and you can write endlessly. Pour Chakra into the bottle, and it will produce an endless supply of ink."
Simple and straightforward.
So, as long as I bring any one of these three items, I can keep writing without interruption?
Good grief. She'd gone and made three treasures just to prod me into updating... Sage of Six Paths, could you come do something about your mom?!
Wu Yu knew there was no getting out of it this time, so he settled down and tried holding the little black notebook in both hands. He'd call it the "Infinite Notebook." Then he poured Chakra into it and concentrated.
Sure enough, a line of ink appeared on the blank page in a flash: Where was I last time?
