Shattered Core Ascension

A menial disciple with a shattered dantian is repeatedly humiliated, but by chance falls into an ancient relic and obtains the 'Shattered Core Art', using his broken core to rebuild his cultivation foundation. After making a name for himself in the sect competition, he is drawn into sect infighting and a great calamity of the world, climbing to the top step by step in a treacherous cultivation world. — Description from novelcodex.org
