A smile touched Bai Zhi's face. Then she heard the staff member say, "We will have an SS-level superpower user escort you home. If you do not require this service, you can simply sign your name here."
After inspecting the document, she said, "I do."
She then stepped aside, letting Xiao Yu and the others see the Crystal Stone.
The Crystal Stone was a little larger than a fist, while the brown rock next to it was less than half a fist in size.
Xiao Yu walked up to the Crystal Stone and reached out to touch it. A gentle warmth spread into her palm. She exclaimed in surprise, "It really is warm."
The Crystal Stone was a bit like a modern-day hand warmer, but unlike a hand warmer, this stone maintained a constant temperature indefinitely.
Xing Fan leaned in closer too. "This is the first time I've ever seen a Crystal Stone like this. It looks like there's a fire inside."
