He turned around and went downstairs. 
"Wait." Jing Xuan said suspiciously, "It's really lost? You didn't hide it?" He didn't want to accept the fact that his pet was lost, it must be this hideous wolf hiding his Xiao Di!
Yan Yifan turned around intolerably and said, "Are you a dunce? We live in the same yard. Even if I wanted to hide it, I have to move to a different bedroom and then hide."
"Then," Jing Xuan lifted his own chin as if accepting the fact that their pet really was lost, "It turns out that you are not suitable for keeping pets at all. You are an irresponsible owner." He then pointed at himself, "I am the most qualified owner." The hairball must have thought so too.
"..." Yan Yifan ignored the dragon that had flattered himself. 
"Hey! If I find Xiao Di first, it belongs to me now." Jing Xuan announced unilaterally. 
"What?" Yan Yifan looked at him in suspicion, "Did you hide my Lulu?" 
"Don't slander me." Jing Xuan walked down the stairs and hurried past him, "I won't tell you, I'm going to find Xiao Di." 
Yan Yifan thought that his behavior was a bit suspicious, so he decided to follow Jing Xuan.
Does everyone remember the bad thing the son-of-the-richest-man did last time? He is very sensitive to his own smell. Even after washing the hairball twice with soap, it still smelt like him after a while. 
"Why are you following me?" Jing Xuan found that the stinky wolf was following him, so he stopped to drive people away, "Hey, Fulton University is so big. We should split up and look for it on our own." 
"Did you put any tracking spells on Lulu?" Yan Yifan asked.
Otherwise, how could 708 have such strong self-confidence in finding Lulu.
Jing Xuan curled his lips, "I don't have that great of an ability." Normally most people have either a talent in Martial Arts or Spell casting, not both. Even if they have both, it was not necessarily a good thing as it might limit their improvements.
Focusing on one talent is the wisest choice. 
"Then why are you so sure?" Yan Yifan continued to follow him.
"Nothing, I just want to say Xiao Di belongs to me now if you continue to follow me." Jing Xuan declared as he walked. 
"..." Since Fat Lulu was lost in his room, Yan Yifan didn't make a sound.
The most important thing right now is to find Lulu.
Being a member of the dragon clan, Jing Xuan is sensitive to scents. He concentrated on finding his own scent in the air.
"Hmm..." Not here.
Yan Yifan was shocked when he found out about the method the Pterosaur used to find their pet. 
Furthermore, Diru Beasts are ordinary pets that do not have strong smells on their body.
After thinking for a long time, Yan Yifan still didn't know that the scent that the pterosaur was looking for wasn't the scent of their pet, but of his own. 
A gust of wind blew a faint musky scent into the Pterosaur's nose. His amber eyes lit up, shining like amber in the night.
Found it.
"This direction... is the residence for the professors." Yan Yifan had to remind the unscrupulous 708 in front of him. Although the school had no regulations on disturbing the professors, this was still basic common sense. 
"Yes, is there a problem?" Jing Xuan crossed his arms.
So what if it was the professors' residence? His pet is there.
