It's not written in the book, but according to the research of drama history, Jing Ke is waiting for a good friend to go with Jing Ke. Qin Wuyang is good, but Jing Ke has no reason to give his most concerned things to a stranger. He is more comfortable than he is. Since he is a good friend, he knows everything about his friends. When Qin Wuyang arrived at the Palace of Qin State, he was scared to death. But who is this person? Only Jing Ke knows, and no one else will know. Maybe you can cross over and ask Jing Ke Hanergy to bring me his signature. Thank you.
