In this chapter, we learn that the evil spirit is using the "nanobots" to reprogramme the humans. In order to do so, they must first complete the murder case from idol kay. The only weird thing about the house is that there is no trace of a human being anywhere in it. The purple square on the wall must mean that she is hiding something important. They can purify him before he escapes. They decide to use the mirror of the tribe to reveal the truth of the situation. The evil spirit has activated the nanobots. The humans must use the "spear" of the serpent tribe to block the evil side of the body, the "bear tribe's swords" to separate the evil from the good side, and the "ram tribe staff" to divide the body into two parts. They must also use the arrow of the dragon tribe to travel as far as they can. The power of the arrow whipped them back, but they must try again. The nanobots seem to be moving in the opposite direction of where they are supposed to be. They seem to belong to another person, and that person must have reprogrammed them. They are trying to return to the "evil spirit." The only thing they can do is get rid of all the prisoners and bring them all together in a single place.
