The young master congratulates the master on his achievement of transforming butterflies and tells him that he has done a good job. He also tells the master that he should not have spent so much time in the realm of transformation, because he has not had an immortal ancestor. The master then asks if he has anything unusual with him, and the young master answers that he does have a strange thing with him. He says that he found it in a cave, and that the cave is in the northern part of the country, full of corpses. It seems to contain a kind of magical power, but it is comparatively weaker than the master's power of space. It must also contain a life covenant, which is what ruqi said. The little thing and the life covenant are the same thing. The formulas on the little thing matter the most, the master says, because they are telling the truth about the universe. What the master means by this is that the heavenly sect attacked the house of divinity just for this little thing. It is unclear whether this is the case or not, but the imperial master must have come for this thing, and he must take care of it if the master needs it.
