Regarding the solution, Duanmu Huai thought for only one day, and then... gave up.
After all, thinking really wasn't his forte, so the solution Duanmu Huai eventually came up with was to have Lumiaire and Ann work on devising a solution.
That's right, and if they can't figure it out?
Isn't it obvious? Just eliminate all the Magic Girls!
According to the information Lumiaire got from QB, the QB network has a channel that connects to all Magic Girls. This allows them to recycle the girls' emotions and convert them into energy to be delivered to the Universe when they fall into despair and turn into Witches.
So, if you could reverse engineer the QB network using this channel, you could wipe out all the Magic Girls in this world in an instant.
"But that's way too cruel!"
In response to Duanmu Huai's solution, Ann protested immediately, and then...
"Well, then you guys come up with a less cruel solution."
And thus, Duanmu Huai just simply tossed the responsibility onto them.
