Idiot! So what if I hit you?

Thaddeus's disciple, of course, remembered Alice. 

Most importantly, Thaddeus had instructed before he left that if Alice were to visit the shop again, no matter the time or reason, he should be informed immediately.

"Oh my! It's Miss Alice. Please wait a moment, I'll immediately inform my master. He should be here soon." Thaddeus's disciple, not daring to delay, quickly asked the staff to warmly entertain Alice and her group, leading them to the rest area and serving them the finest coffee.

He then rushed inside, took out a communication crystal, muttered to himself, and the crystal faintly glowed. After conveying the message, the crystal lost its light.

This was how Soulmancers communicated.

The thought is transmitted through the communication crystal to connect with the intended person, which was more efficient than making a phone call or video chatting.
