Using the power of the entire Cave Heaven Paradise, Yan Fei carved out a spatial channel connecting to Dream Island. However, the creation of such a space channel consumes a significant amount of energy, especially a permanent fixed channel. Creating just this one channel depleted one percent of the reserved energy in the Space Crystal Wall. It's important to note that Yan Fei's previous endeavors in creating the sun and moon only depleted one-tenth of the reserve, meaning the energy consumed for this space channel was ten times that of creating the sun and moon.
