Inside the Mountains and Rivers State Diagram, Yi Chen began working on the Fourth Generation Blessed Grotto Heaven.
Piles of various mid- and low-grade Immortal Minerals rose like Great Mountains of different colors.
Under the wrap of Yi Chen's Divine Sense, those Great Mountains lifted into the air one after another.
Then they were enveloped by Blazing Flames.
