He is unwelcomed by the orcs and despised by humans. Fortunately, he awakens the God-level Fusion System and can strengthen his abilities by fusing items.
He can increase his strength tenfold by fusing himself with the genes of an ant. He can enhance his arm strength by fusing the genes of a praying mantis. He can improve his defense tenfold by fusing himself with the genes of a turtle…
After tens of thousands of fusions, an orc with unparalleled power is born into the world…
