Chapter 187: Book of Heaven Burial

At the end of the corridor, there was a stone door that was about as tall as a person. Because it has been covered by the lake for a long time, the dark green stone door looks smooth and covered with layers of fluffy moss, but a mark can be seen vaguely carved on the stone door. And when I saw the mark clearly, I immediately screamed out in excitement - I had seen this mark in my precognitive dream, and the same mark was painted on the dragon's cloak.
