After passing three Birth Trials, it was incredibly difficult for Venerable Masters to activate Birth Charts. Life hearts of most fierce beasts were useless, and it was a daunting task to obtain life hearts that would be useful to them since they belonged to powerful fierce beasts.
In fact, after activating the 18th Birth Chart and passing the third Birth Trial, one would be in a very awkward phase. After all, one would have difficulty activating more Birth Charts, and if one's Birth Charts were destroyed, it would be an incredibly devastating blow. Therefore, Venerable Masters usually would often do everything they could to protect their Birth Charts.

Lu Zhou did not receive a notification for destroying a Birth Chart. Instead, he received a different kind of notification.
