After finding out that somewhere in the Second Realm there was a starship, probably a creation of these Otherworlders, Khal couldn't stop himself from asking several questions to Hao Yu.
He asked numerous questions such as how big it was, how many rooms it had, the layout of its interior, different rooms and locations found inside it, and a description of its outer appearance.
There were even numerous questions such as the materials they were crafted out of or the decorations, which for there perhaps seemed confusing and useless for Khal were extremely important.
Of course, because of this, the founder of the Moon Sect seemed pretty confused about just why did Khal was so eager to learn about the spaceship so much, but after seeing his serious gaze below his calm facade he knew there was a solid reason why he was acting the way he was, thus he decided not to hold back a single thing and described everything to him as clearly as possible.
