Raised on the road following his parents around
Until his mother's sect, Yueyin Gong, was massacred by his shishu and his dad (and mother by extension) was framed, oops!
Yueyin Gong famously safeguarded forbidden and obscure manuals and techniques
Mom gave him a manual and told him to practice it when he was older and take revenge, making sure he would never be betrayed the way she was, and then she died to join her husband because wuxia be like that
Was supposed to go to his paternal aunt, a noblewoman who could keep him safe, but ended up getting lost and destitute
A wandering daozhang, Cihong Sanren, took pity on him and took him as her student
Against shifu and mom's wishes he wanted to take revenge as soon as possible so decided to use the manual that was passed down to him, successfully gaining the Xianzhishenyan, but imperfectly, dooming him to a short life and restricted neili
Took down his shishu and cleared his parents name as a teen, meeting
Qin Yuzhu along the way
Cihong Sanren would eventually give up her immortality and sacrifice herself in an attempt to bring down their enemies once and for all, her neili transferring to him and giving him the chance to live a normal life
Took the name Canghong as a tribute (though some people think it's a joke) and withdrew from jianghu, opting to live freely like his shifu wanted for him, carrying the secrets of his mother's sect with him, dodging people who are still pursuing said secrets along the way
