Fired from the Start? I Switch to an Eight-Winged Fallen Angel

Su Ming transmigrates into an era where everyone can choose a class. From the start, he awakens the supreme talent [Heart of an Angel], only to be set up by a villainous clan. Not only is his younger sister gravely injured, but his talent is forcibly ripped away, leaving him a cripple and casting him into the Endless Demon Caves. Looking at his sister, barely clinging to life in his arms, Su Ming completely abandons so-called humanity and mercy. He makes a symbiotic pact with the Abyss's dark essence! The golden foundation deep in his soul forcibly suppresses the darkness, transforming him into the one and only hidden class: [Eight-Winged Fallen Angel]! Lost your divinity? Then I'll slaughter my way through everything with overwhelming force! If the divine insist on standing above all, then I'll become the deepest darkness! He becomes a walking abyss, fighting his way from the edge of the Demon Caves into the heart of enemy territory. If gods stand in his way, he kills them. If demons stand in his way, he slaughters them. He needs no teammates and accepts no surrenders. Facing a monstrous tide of alien beasts, Su Ming's mismatched eyes are as cold as ice. He raises a hand, and dark-golden lightning becomes a rain of swords, slicing thousands upon thousands of aliens into bloody mist. He devours their life force to strengthen himself. Wherever he goes, bloodthirsty aliens and the lofty plutocrats' lackeys alike are cut down by dark wind blades, reduced to dry bones. As the killing continues, more skills unlock. When the alien emperor's army reaches the city gates, and humanity's vaunted holy-class users retreat step by step, wailing in despair, the cripple they had trampled and declared dead stands alone in the sky. With one strike, he severs the alien emperor's head. Then he turns, pointing his sword at the terrified plutocrats on the city walls. “I took care of those useless fools along the way. Now it's your turn to pay your debts!”
