The Grotto Heaven became active and dynamic, gradually experiencing rainy weather, the changing of seasons, and various complex climates.
An illusion of a Cyan Dragon appeared in the east, a White Tiger illusion in the west, a Vermilion Bird illusion in the south, and a Black Tortoise illusion in the north. The illusions of the Four Symbols Holy Beasts all manifested, then merged into the Grotto Heaven to strengthen it, making the Grotto Heaven more solid.
Spiritual Qi continued to evolve and expand.
Boom boom boom!
The Grotto Heaven's expansion speed was somewhat unexpectedly fast.
Lu Xuanji had to slow the pace, gradually moving towards stability.
Time passed, and ten years later, the expansion of the Grotto Heaven ended.
The periphery of the Grotto Heaven derived a world membrane, continuously surrounding and reinforcing the world. The laws within the Grotto Heaven continually emerged, densely scattered throughout the Grotto Heaven.
