Mrs. Ai'er still had some business to attend to. She had a livestream, so she took a hovercar and headed back first.
Before leaving, Mrs. Ai'er had given her this Crystal Stone.
It was transparent, looking no different from a simple piece of glass.
But when she clutched it tightly in her palm and released a bit of spiritual power, she could feel it growing warm.
Mrs. Ai'er had told her that the model of Mental Training Device she currently had featured a slot on top for the Crystal Stone. All she had to do was insert the Crystal Stone during her next training session to use it.
According to Mrs. Ai'er, training with the Crystal Stone would be twice as effective.
She didn't have time to experiment with it today. She would have to try it tomorrow morning.
