Chapter 691: Chapter 143 Speak Less, Devour More, Reaching Seventh Rank is No Big Deal

Burning Sea.

A notorious forbidden land of the Zixiao Sect.

Chu Ning had previously seen an introduction to the Burning Sea in the Elixir Tower Association's Imperial Library when he was reading about the various realms' information.

The Ancestral Master of the Zixiao Sect chose to establish the sect here because it is where a hundred Earth Fires converge.

Earth Fire is not only necessary for alchemists, but also important for some cultivators who absorb fire attribute techniques and divine skills.

The Ancestral Master used his divine powers to control these Earth Fires within a certain area, originally intending them to be conquered and cultivated by disciples in the future.

However, these Earth Fires began to merge and converge when contained, and eventually formed a sea of flames that even Divine Transformation Experts dared not touch lightly.

From then on, this sea of flames became a forbidden land for the Zixiao Sect.
