Also known as Shengshi, courtesy name Huaijin. Shizi of Zhenguogong, son of Princess Yongle (the Emperor's full-blooded elder sister). A young prodigy who became Tanhualang at sixteen and earned the title 'young god of slaughter' at eighteen. He personally led hundreds of black-armored cavalry to rescue Yujia after being summoned with a donation of ten thousand taels of gold. Noble in appearance with dragon-phoenix bearing, sharp and imposing like an unsheathed sword, yet pragmatic and mercenary in negotiations.
