In this chapter, Dr. An tells us that he still thinks they can save the boy's life by using the latest technology to repair his broken arm. He also says that if the boy wants to use an artificial limb, he can do so. Dr. Aofei, however, thinks that the boy is too smart to take the risk of using an artificial arm. Instead, he suggests that they should ask the boy if he would like to use the artificial arm after he recovers his strength. He says that he thinks it's better to discuss the matter without others, since he thinks they shouldn't be making medical decisions for the patient. He then tells the doctor that if he only needs to save the life of the boy, then he has a lot of options, but if he needs to completely restore the broken arm, he has to think about the consequences of using the new technology. The doctor tells him that the patient is finally getting better, and that they've found some clues to the explosion at the university. He invites the boy to dinner, and tells him to look at his arm, which has healed. He tells the boy that he'll tell him more about the explosion later, and then asks him to stay at the hospital as long as he likes.
