The Heart-Tempering Chronicles of the Jianghu

On the night of the martial arts tournament, Gu Qingya, at sixteen, experienced both his greatest glory and the most unforgettable bloodshed of his life. His father fell before him, knowing his death was near, clutching his hand and whispering: guard what the Gu family holds. The Blood-Robe Tower wiped out his entire family in one night, sparing not even a child, all for the sake of that same unnamed 'thing'. Carrying his feverish sister and clutching a blood-stained bronze lock, he fled into the vast darkness. — Description from novelcodex.org
