Sleeve Universe, an exceptionally rare Immortal's secret technique.
Qiu Changtian reflected on the past. Over his lifetime, he had encountered countless cultivators, yet only three had ever used this technique: Lei Caiyan, the Chi Song Immortal, and the Wan Xiang Immortal.
Lei Caiyan was a spy planted by the Hell Path in the Heavenly Craft Workshop. Considering the scarcity of the Sleeve Universe technique, Qiu Changtian was inclined to believe that Master Luo likely knew this technique and passed it down to Lei Caiyan.
The Chi Song Immortal, being the original owner of the *Heavenly Void and Natural Spirit Tome*, naturally possessed mastery over this technique. As for the Wan Xiang Immortal, the origin of his knowledge remains unknown, but Qiu Changtian recalls that the Heaven-Mending Stone shard of the Penglai Yuqing View was hidden by the Wan Xiang Immortal within an independent dimension.
