Yu Qingtan transformed into a member of the Sea Clan and quietly operated beneath Oujiang Immortal City. She utilized her skills in artifact refinement and formation techniques to repair the damaged Formation Base bit by bit. At the same time, she integrated rare materials obtained from the Myriad Beasts Secret Realm to enhance the quality of the Formation Base.
To expedite the progress, Yu Qingtan even had her clone, the Green Holy Maiden, come to this side as well, sneaking into Ruzhao Immortal City and replicating the process to secretly repair the formations. Her actions were cautious and circumspect, for fear of being detected by the Sea Clan.
After seven days of strenuous effort, Yu Qingtan finally completed the repair of the Protective City Formations of both Oujiang Immortal City and Ruzhao Immortal City, raising their quality to the upper echelon of the Fourth Stage.
