The Dual Mysterious Treasure Map serves as a foundation for the second and third secret realms, and also as a pass for entering and exiting these realms.
Lu Bei has the Feather Transformation Sect Master Seal, inherited from his master, which he has easily refined. With it, he has gained the ability to freely enter and exit the secret realm, as well as the authority to seal it off.
By the secret realm, he doesn't mean the second or third, but all of the secret realms, including the first one.
Bai Jin had once mentioned that cultivators in the Integration Period have the divine ability to stitch together secret realms, altering everything within them at will. Although Lu Bei is not in the Integration Period, inheriting the Dual Mysterious Treasure Map is equivalent to gaining partial authority over the secret realms.
As a so-called "authority dog", he began cleaning up as soon as he learned about his power.
This means what is commonly known as kicking people out.
