Invitation to join the Divine Night Sect

Going back to the flying ice mountain, Bai Long first focused on using all the materials he purchased to further upgrade the flying ice mountain before starting to place his entire attention of cultivating. 

All of this was due to what that letter which Hu Lifen had given him. 

Other than explaining about the gift she had given him, the folded paper contained an invitation inside it. 

An invitation to join the Divine Night Sect as an inner disciple. 

No matter how much oblivious Bai Long was to the situation on the Mainland and how everything was completely new to him, he wasn't an idiot that didn't know about the strongest forces on it. 

And the Divine Night Sect, it was one of the peak forces which represented the apex of power on the Mainland.
