In the meantime, Bing'er tries to convince himself that he's a fool. He's afraid of pain, he says, and that's why he tried to kill himself with an arrow. He doesn't want to tell Bing about his past, because he'd be sent home if he knew. He also wants to know how he got the jewel, and how he almost got shot by the princess. He tells Bing that he won't ever marry the princess, even if he were to be single. He says that today is his birthday, which means that he lied to his godfather on the spot. He then tells Bing about the "Tianggong battalion" , which is a special organization of the empire. It's made up of a few guys who are masters of archery. They're great assassins, and they're also the ones who help the empire when it's faced with a crisis. When the empire was facing a crisis, the battalion took action. The empire was terrified, but the battalion was amazing. Ten days later, they finally returned to the city. The commander gave him a letter, asking him to find a two-person group to join the battalion.
