Reborn as a Trouble-Making Ironhead

(An important point, repeated three times: no romance, no romance, no romance!) Jiang Tietou died young in his previous life, and his death was deeply unfair! After dying, he refused to be reincarnated and spent years wreaking havoc in the underworld, until Great-Grandma Jiang finally had enough and spent all the merit she'd accumulated over decades to let him be reborn, with a speech-based golden finger thrown in for good measure! And so, reborn at the age of three and armed with a golden finger, Jiang Tietou began his wonderful life of raising hell and becoming the mightiest demon around!
