This chapter's epigraph is from a poem by the famous poet Siddhartha. It's a quote from the poem "Siddhartha," in which he says, "I am the vessel of the spirit of the tower. I have been here for one million years." The poem is a reference to the fact that the tower is the home of the "sky soul race," a group of people who have been living in the sky for a very long time. They are not physically human, but rather, they are "pure consciousness." The tower was designed to be a place where the master's relatives could come and train. The tower's owner, the original owner, was supposed to have been a descendant of the master. The man who owns the tower doesn't seem to be related to humans at all, but he is powerful enough to test the man's talent. This is the "ultimate test" , and the man who controls the tower will have to defeat the man.
