On the way back to Yuzhu Manor, Duan Yun did not speed up. It wasn't because he wanted a leisurely journey, but because he was studying the usage of the Unparalleled Sword all along.
He had already mastered the ability to gather thunder into a sword through the Unparalleled Sword, but now, an even more crucial secret needed to be understood, which was "opening the gate."
The Great Heavenly Dog used this Divine Sword to open the portal to the Heavenly Court, thereby learning the method of "creating humans." The place where she was later torn apart, White Jade City, should also be a place similar to the Heavenly Court, only accessible through the Unparalleled Sword.
According to Duan Yun's understanding, the Heavenly Court, White Jade City, and the mortal realm should have a thick barrier that separates humans from immortals.
This would prevent a scenario where immortals roam the mortal world casually.
