The Nine Heavens Immortal Emperor Palace is a sect founded by Fang Bai, and he naturally attaches great importance to its defense.
Before leaving the Nine Heavens Immortal Emperor Palace years ago, Fang Bai set up several layers of offensive and defensive formations both inside and outside. As long as the reserve of spirit stones is sufficiently abundant, the formations can maintain normal operation.
Moreover, before he left, Fang Bai left behind a large number of spirit stones, enough to keep the formation running for several months.
Today, the Nine Heavens Immortal Emperor Palace has many Thunder Tribulation Experts stationed there, the most powerful of whom is Xuan Feng Venerable, a loose cultivator whom Fang Bai met in the Blood Sea Desert of the Eastern Desolate Continent.
