章 506: Let Me Start with a Thousand Books

"The Dragon Severing Lock is usually the final line of defense used for a fortress. It's designed such that one would be unable to break it unless one's cultivation reaches the required level... Even the celestial designer who set up the trap himself would find it hard to open it!"
