Inside a dream realm, Meng Qiu Zhen searches Tu clan village’s real underground prison, a maze of thousands of intersecting paths dug through a whole mountain, and finds traces of Earth Tunnel there. He judges the mountain to be of famous mountain level and to hold a natural Earth Tunnel, and says Tu clan village developed that tunnel only slightly and still gained a large amount of resources, which is why it could nurture two rank four elders.
