In the middle realm of the Southern Heaven Ancient Realm, every grade-six Celestial Mansion had its own base. The identity token and Accumulative Point Jade one carried would only grant one entry to the corresponding base. There was no way for outsiders to enter another mansion's base. If one tried to enter by force, it would trigger the base's defensive Formation that was set up by the mansion's Celestial Lord. Needless to say, it was not a Formation that Ten Directions Celestial Dukes were capable of breaching.
If this group of disciples from the Martial Battle Mansion stayed in their base, it would be impossible for Duan Ling Tian to get to them no matter how strong he was. Alas, they had left the base earlier to watch Duan Ling Tian and Heng Feng's fight. They were returning to the base after Heng Feng was defeated by Duan Ling Tian. Who knew Duan Ling Tian would bar their way as soon as they turned around.
