The high-ranking elders of the Heaven and Earth Gate stood aboard the flagship, gazing at the Black Water Sea Region burning with Bone-Corroding Demon Flame ahead.
They were filled with helplessness.
The Bone-Corroding Demon Flame was one of the most overbearing spiritual flames in the Demon Realm. If even a trace touched someone, a Dao God realm martial artist would instantly turn to ash, while a martial artist in the Great Purity Dao Fruit Realm would have their soul burned apart. Only a Grand Luo Dao Fruit martial artist could barely protect themselves.
The Bone-Corroding Demon Flame raged across the Water Mirror Sea.
The martial artists of the Heaven and Earth Gate stationed in the Black Water Sea Region retreated at top speed.
The Black Water Sea Region had originally been guarded by one hundred thousand Heaven and Earth Gate martial artists, but by the time they had all withdrawn, only a little over ten thousand remained.
Most of the others had already died within the Bone-Corroding Demon Flame.
Elder Ma sighed mournfully. "The Tianshui Sect clearly came prepared for this operation. They know our defenses in the Black Water Sea Region like the backs of their hands. They even know exactly where we store our supplies."
"We have spies within the Tianshui Sect, so naturally, the Tianshui Sect has spies within our Heaven and Earth Gate as well!"
Elder Ma had basically confirmed that a spy had been providing intelligence to the Tianshui Sect.
Otherwise, the Tianshui Sect could not have found the Black Dragon Nest so easily.
Elder Ma continued, "Think about it carefully. From the moment Huang Lin appeared in the Black Water Sea Region to the moment Lin Bai stormed into the Black Dragon Nest and released the Bone-Corroding Demon Flame, only about an hour passed.
