Actually, Ye Qingtang and the disciples of the Great Immortal Temple did not know much about Destruction-level divine weapons. Even the experienced and knowledgeable Zhang Chi had never heard of Destruction-level weapons.
But if they were to consider things from the price point of view, Destruction-level divine weapons sold in high-tier ancient cities should be much higher than Heaven-level divine weapons.
Ye Qingtang was very curious about the owner of these soul bones. The cultivation level of this owner was probably on par with that of mighty figures like the High Monk and Heaven Ascension Sect Master.
After the death of the soul bone owner, his Deity Ocean turned into this legacy. All the rare treasures sold in the ancient cities were probably his possessions.
Earlier on, Ye Qingtang even saw a Fiendcelestial Beast-level spirit animal in the shop.
However, Ye Qingtang was not interested in spirit animals now, so she did not buy any.
