What Does It Mean That I Am the Biggest Alien?

He traveled through time and became a prisoner on death row who was about to be hanged, but suddenly encountered a monster. Only then did Ian find out. He can take away the abilities of monsters he killed with his own hands. Kill the bone spurs and get strong bones. Kill the Butcher and get the Flesh Furnace. Kill the robbing dogs and gain stealth. While other extraordinary beings were still struggling to advance along fixed genealogies, Ian had begun to fuse the abilities of different monsters into one. He originally just wanted to live well, after all, traveling through time was not easy. But he didn't expect that in the end he would become the biggest anomaly in this world full of anomalies!
