A Shooting Star

 Within the Bank of the Universe, Li Xiandao held the celestial gate key and was in deep thought.

 Seven asked, "What are you thinking about?"

 "I am just thinking, Celestial World is so huge and far exceeds the Nine Skies and Ten Lands, so why do they want to control it?" Li Xiandao didn't understand.

 Seven smiled, "Then, the way you are thinking is wrong."

 "What do you mean?" Li Xiandao didn't understand.

 "Do you think that Celestial World is just a big world controlled by a celestial dynasty?" Seven asked.

 Li Xiandao nodded. He hadn't been to Celestial World, so he didn't understand it.

 The books within the Ten Thousand Country Book Depository were all rare techniques and there weren't any records of the current Celestial World.

 After 10,000 years, time flowed and many of the records available were not relevant and became just a part of history.
