In the ancient era, numerous events marked history and are still remembered today.
Although the Tang Yin world does not have too much writing from that era, there are still some, and among those, the most memorable was the appearance of the Heir of Death.
He appeared as a small fry in the First World; no one paid attention to him, and everyone underestimated him. He was not weak, but he was not at the level of the Gods of that era. Some records describe him as being in the Realm of the Law, but others put him at the level of the Divine Ruler, the Cultivation Realm, where Tang Yin was in the past.
Although it is not possible to know exactly how strong this person was, what is clear is that he was not too powerful at the cultivation level.
