Gold Dharmic Lotus, Contaminated Spiritual Mountain, Black Qi's Bane

Hui Zhang forcefully opened the Desire World Sky inside the Lapis Lazuli Land, awakening all the Desire World Sky Demon. 

The demons flooded Lapis Lazuli Land and wreaked havoc as they pleased. 

Fortunately, due to the Buddha Character Boundary, they were trapped inside Lapis Lazuli Land, so their targets were only limited to those who entered the land. 

Only Shi Ying, Jing Hui, and the other Prodigies were left inside the land. 

They took refuge inside Guanyin Hall and started chanting mantras to form a smaller version of the Buddha Character Boundary around them, hence isolating the demons.

Then, a large crack appeared in the deepest part of the land and started to crumble inward. Vast amounts of Buddhist Light burst from the crumbling crack and flooded the land with a holistic and pure qi.
