Generally, according to the rules of Dragon Emperor Pavilion, the study room of Dragon Emperor was only accessible to cleaners and inspectors. Most of the time, the study room was locked.
However, Zhang Tie was an exception; because Zhang Tie was the highest official in Dragon Emperor Pavilion who had some privileges for real. Additionally, Dragon Emperor who had disappeared for over 900 years was already a symbol in Dragon Emperor Immortal Palace. Although nobody would like to admit it in the public, everyone was crystal clear that the Dragon Emperor probably has been dead. On this occasion, the magnificent qi field over Dragon Emperor Pavilion gradually declined; especially after Dragon Emperor Immortal Palace shrunk their force back to Dragon Emperor Big Domain. The so-called Dragon Emperor Pavilion had already become a memorial hall, where nobody else would believe that the Dragon Emperor would come back.
