In this chapter, we learn that the spirit world has developed a special program that can detect the presence of special spirits. In other words, if a special spirit is nearby, it means that the other ancestors are nearby too. This means that if Renyan sees a picture of his ancestor, he can guess who that ancestor is. Renyan's diary can also be displayed in the same way, so Renyan can see that his ancestor's spiritual power reaction has been detected. This is a big deal, Renyan says, because his soul is tied to something in reality, and even if the picture explodes, it will always return to its original place. This also means that Renyan will always be able to find his ancestor even if he is dead, because Renyan has a special connection to his soul. The author of this chapter tells Renyan that after Renyan left, he learned how to make a new dish by slapping slap slap slap. He doesn't know whether Renyan likes the new dish or not, but he does know that he's not happy. He says that if he were injured, he'd be back soon, but when Renyan passed by a neighboring city, a task on excavating a tower came up, and Renyan was supposed to come back home after finishing the task. He's going to have a reunion with Renyan and his dad after he finishes the excavation.
