Prisoner of the Dragon Nine Changes,Prisoner of the dragon soul, change is the heart. The world is going to go where, and where to put the hearts. The most important thing is that you can't get rid of the dirt in the world, and you can't warm up the fickle hearts. The wood of Yin, in the end, is just a coffin tomb to bury the world. A different world is in the heart, but also in the "Nine Changes of the Dragon".
