This special power was acting on his entire body, washing over every inch of his skin, every strand of his muscle. The impurities within his body were all forced out one by one. This phenomenon was akin to the legendary marrow cleansing, pulse severing, and rebirth transformation.
Su Yu lay on the ground, experiencing this extraordinary phenomenon. Qin Jiagui and others paid attention to Su Yu's left arm because sheets of black scales emerged from his left arm, starting from his left hand and extending all the way up, rapidly covering his entire left arm up to his shoulder. This newly emerged black scale flickered and shone, with a hint of black light. Even in the darkness, everyone could clearly see the terrifying aura emitting from this arm. It seemed like Su Yu could bring about catastrophic destruction just by waving his left arm.
In Su Yu's mind, the pieces of information flickered. He ascended again, upgrading from a "First-Level" to a "Second-Level Black Iron Warrior".
