He had read the Daoist Canon since childhood, and within the books, there were iron rules. After entering the Mausoleum of Zhou, Chen Changsheng could plunder all the treasures and magical artifacts in the nine stone rooms, however, he had never thought of opening the black stone coffin. It was extremely possible for Zhou Dufu’s most precious property to be hidden inside, but due to Xu Yourong’s respect for the person within the coffin, he did not even consider the idea.
At this moment, only after hearing what Xu Yourong had said did he understand that even if he wanted to open the obsidian coffin earlier, it was not possible.
Only a key could open a lock. If Zhou Dufu did not want any person to disturb his long slumber, then the mountain-like obsidian coffin would naturally be very hard to open.
