After leaving Asharia, Shiro didn't have too many worries. All of Asharia's problems could be handled by Nan Tian since she had prepared all the necessary tools before Rokarn's fight.
She could somewhat confidently leave on her own journey without worrying. Of course, if something major did happen, she would not hesitate to unseal her destruction divinity and teleport back. While it may not be beneficial to perform surgery on herself multiple times, it was still better than ignoring an emergency.
While she did want to hang out with Madison after being away for a while, time didn't allow it. With the second half coming in less than a week, she couldn't slack on her preparations.
After she had stepped through the teleporter, Shiro found herself in London. Or rather, what's left of London.
Seeing all of the broken buildings, shattered dungeons and monsters that roamed around, Shiro stretched her body and pulled out the tome that Hemera had given her.
