"Blue Lake is the only large lake in the upper reaches of the Huai River. We call it Blue Lake, while the people from the Snow Mountain Domain and the Northern Court refer to it as Kyunggyel Gyatso, meaning 'Ice Ocean Dharma Sound,' a tide whose resonance can inspire enlightenment."
"Unlike the depths and breadth of Jianghuai Great Marsh, Blue Lake stretches narrowly and elongates quite extensively. If one really wants to describe its shape, it is more akin to Weishan Lake along the canal, where its north-to-south length is more than seven times its east-to-west width."
"The southern shoreline is smooth, while the northern end is fragmented with hills, scattered with islands and landmasses, a small part of which extends into the territory of the Northern Court."
"Perhaps due to the cold weather, I've observed that, despite having the same size, the number of Demon Beasts in Blue Lake is roughly thirty percent less than the middle and lower reaches, hmm, thank you."
