"I'm Garett, I'm here to pay a visit to the Valkyrie Luna" Liu Yang spoke courteously. He mentioned her because he doesn't know about Lida's identity within the Waetor Kingdom.
"So you are Garett… Do you have proof of that? You can be anyone in disguise." The guard was ordered to let a person named Garett in, but he was not convinced by Liu Yang's words.
Anyone can come on the scene and say that he is Garett. Without proof, the guard will not be convinced.
"I have no proof that I am Garett, but you can call Valkyrie Luna to come here, she will recognize me" Liu Yang replied. He really had no proof that his name is Garett.
The name used by Liu Yang today is false. So there was nothing he could use to prove that he is really Garett.
The only way to prove it was to ask Valkyrie Luna or Lida to show up at the entrance.
