"The most powerful feature of this Heart-to-Heart Bean is not its ability to transmit sound, but rather its capacity to break through the restrictions of any Barrier to achieve precise sound transmission and location tracking." Xia Hua was extremely proud of the Heart-to-Heart Bean's function, as this was one of her most formidable minor techniques.
When she spoke of any Barrier, she truly meant *any* Barrier. She could guarantee that even in a Barrier trapping a Demon God, as long as a demon inside possessed her Heart-to-Heart Bean, she could communicate with them and pinpoint their location!
Unfortunately, she had only made five Heart-to-Heart Beans. The first was a prototype, which was a great success; the second was given to Luo, who carried it with him and turned to dust along with the sacrifice; the third and fourth had now been given to Jiang Qingyu and Song Wu; and she currently had only one left in her possession.
