Daoist White Bird had obtained this voice-retention stone by chance. Because he didn't know whether the message was true or false, and he was leading a very carefree life now, he didn't really feel moved in his heart by the treasure trove of the heretic king.
He was eating well and he could play with women whenever he wanted to. Hence, he decided to take things easy and would only flee to the Darkness Continent in search of the treasure trove if he was exposed.
However, he couldn't have expected that because of kidnapping Lu Zhiruo and offending Sun Mo, he would have gotten killed and even his nest had been searched through.
Other than the voice-retention stone, there were still some jewels and jade artifacts in the tiny wooden chest. All of them were rare valuables that were worth plenty of money.
Daoist White Bird was prepared to bring these items along when he fled. After all, gold was simply too heavy.
