Who is Bo Hai?

"Why do always want me to take you to the library?" Arya asked as she sat next to Luhan watching him read. Luhan smiled. 

"It appears you don't know me at all," said Luhan and smirked. 

"Ohoo!" Arya moved closer. "Are you trying to say that I have never understand and that you reading is one habit I don't about you?" Arya asked.

"Yes," Luhan and nodded and looked at Arya. Arya could not hold his gaze and she turned away.

"I will do it slowly and get to know better," she said and left. "I will drop in later when it's time for lunch," Luhan decided to utilise that chance to get read books that are restricted and top secret. 

He wanted to know about the Demon Realm more and about his Shifu. Since he could nit ask anyone, he wanted to see if there are books available recorded by the historians and scribes. He walked towards the dark section but he was interrupted. 

"Luhan, Arya told me you are here," Bo Hai walked in.
