Bab 51: Chapter 50 It's Up to You to Make the Master's Tonic

Jin Guang looked down at him and said slowly, "Beyond the Xumi Vein, countries abound; the land is vast and its edges unknown. I am only aware of a thing or two..."

"This Flying Rock Building is indeed part of the Great Chu Country—it is a legitimate... a proper Demonic Path with a massive scale, it drains people's spirit, turning them into puppets.

The Flying Rock Building indeed belonged to a sect within the Great Chu, and it had a very large scale—it was an esteemed and upright sect.
