Me, Luck EX, Invincible

[Full Rewrite Pending!] After sealing the Lord of the Abyss in the Infinite Worlds, Gu Qingce cleared the game and returned to the day he was taken back into the Gu family at eighteen. He was about to face his relatives' coldness, his good brother's smug arrogance, and everyone's hatred, eventually ending up with both legs disabled, his ability crippled, and himself thrown out of the house. Gu Qingce didn't care: That's it? * Gu Qingce's old ability, "Luck," was rated E. Its effect was so insignificant it was practically nonexistent. "Luck? I could pick up money on the way out and call that lucky." "You call that ability of his a supernatural power?" "Who'd want to team up with Gu Qingce...? He's nothing but dead weight." But who could have guessed what would happen during the awakening test... Gu Qingce: "I say I'm lucky, and I'll find the quest item in no time." So Gu Qingce looked up and saw the target item hanging from a tree. Gu Qingce: "I say I'm lucky, and I won't get lost." So Gu Qingce walked straight out of the maze that had trapped every other Awakened. Gu Qingce: "I say you're unlucky. Your master doesn't acknowledge you." So the evil god promptly turned around and swallowed its follower whole. Everyone cried out in shock: You call that "luck"? One day, after overusing his ability, Gu Qingce was rescued by his roommate, Philthelos, who also replenished his magic. When Gu Qingce woke up, he realized his good roommate... looked a little familiar. Long, glossy black hair reached the floor. Abyss-black horns grew from his head, and the broken sealing runes on his chest glowed red. Wait... Isn't this the Lord of the Abyss, the final boss of the Infinite Worlds? Gu Qingce narrowed his dark eyes. "Are you going back on your own, or do I have to seal you away again?" The shadow of the abyss churned behind Philthelos, and his blood-red eyes brimmed with turbulent emotion. No one knew that the universally revered Philthelos wasn't human at all, but the Lord of the Abyss from the Infinite Worlds. He had come for Gu Qingce alone.
