This Ancient God Arm belonged to the Human Emperor Rain Master. He was once exceedingly powerful, one of the strongest among the Emperors, and one of the oldest existences. However, in a certain era, he met his end at the hands of the Demon Emperor of the "Grass Character Immortal Sword Scripture," and both his Divine Soul and body were obliterated, facing complete annihilation.
Only an arm managed to pierce through countless light-years of spacetime, traveling through the desolate Dead Silent Starry Sky for untold ages, and finally ended up in the Ancient Divine Domain. It completely lost its energy and fell into a world, where it was acquired by the Ancient God Ancestor Master of that era, thus creating a myth among the Medium Thousand World Cluster.
The Ancient God Ancestor Master should not have been limited to the Heavenly Human Peak.
