There is a place in Nanjing called Shenge Minggang. The people inside are monsters with "yin and yang eyes" among the people. Nanting and Youjing have lived for a long time. They are drifting in the world and passing through their obsessions. They use a pair of eyes to see through the world, which is sad and confused, wandering and prosperous. In the mission of wiping out the soul-eaters again, Nanting wanders in the world and goes to find Yujing with his obsession.
Intention: There will always be someone who will search for you across mountains and seas with obsession
