In ancient times, the Venerable Tongtian, founder of the Celestial Hall, fought the four Spirit Emperors of his era and their cultivator armies for a piece of blessed land to establish his faction on. Back then, 6,000 disciples followed Tongtian, and all died for his cause. To honor their service, the Venerable Tongtian created the Funerary Rite of the Grand Legion, a ritual formation used by the Celestial Hall to commemorate the deeds of their deceased heroes.
Though initially not meant for battle, the Funerary Rite enabled legions of experts to unite as a single armored army that could not only release horrifying destructive strikes, but also cast grand barriers that built on the overlapping cultivation bases to resist or destroy those unfortunate enough to stand in their way.
