Gon and Killua

*Gon and Killua are on the 200th floor, their goal is to reach the top. Lately, they have been training with Master Wing and Zushi, practicing the use of the Nen. After their practice, Gon and Killua would chat with Zushi for a while before continuing* Zushi: "You guys learned Nen very quickly! It's awesome!" *Killua puts his hands behind his head and shrugs nonchalantly.* Killua: "The truth is that it was easy, I don't think it's a life achievement or anything like that."
