The Dark Altar Lineage has cultivated a total of seventeen True Spirit Demon Trees in the West Mountain Floating Domain. The reason there are only sixteen trees in the cave is completely because the one in the Celestial Yin Mountain Range has been refined.
Whether it's the West Mountain Floating Domain, or the Outer Path Hidden Demon Sect, few know about this except for the high echelon of the Outer Path Hidden Demon Sect. The Lu Family Corpse Ancestor absolutely cannot be a cultivator of the Outer Path Hidden Demon Sect, so there is only one possibility—the words of the Lu Family Corpse Ancestor absolutely exist and are not nonsense.
But actually, this point is not the most shocking to him; the most shocking is actually the Spirit-Extinguishing Ghost Qi that can refine the True Spirit Demon Tree. Behind its existence, there are even multiple Top-Grade Golden Cores.
There's even an Undying Celestial Yin Golden Core!
