As Estrella went to look for Keiko, Shiro started to sketch out the magic circle that she was planning to carve. In addition to this, she would add a few notes on how to redirect most of the mana towards her so that she could speed up her recovery.
Referencing quite a few of Kuromi's notes and information from her own studies, Shiro managed to draw up a few prototypes that still needed to be tested.
However, she wasn't going to test them just yet since she was still waiting on Estrella to come back safely with Keiko.
Looking out of the window, she could only hope that nothing has gone wrong.
"Don't worry, I'm sure they'll come back safely." Nan Tian said after seeing her worried look.
"Mn, you can go back and rest now. I'll stay up for a little longer. If anything happens, I'll call for you ok?" Shiro smiled.
Nodding his head, Nan Tian tidied up the room a little before leaving after saying goodnight.
