Nie Tian's mother died young, his father is unknown, and he has no talent for cultivation, so he is looked down upon by his clan. In a duel with children from the same clan, Nie Tian was once at a disadvantage due to his realm difference and almost lost his life, but at the critical moment, he burst out with a strange power and defeated his opponent. However, this led to Nie Tian's grandfather being forced to give up the position of the head of the family, which made Nie Tian understand the consequences of his recklessness and decided to concentrate on cultivation from then on and stop meaningless fighting. Later, in an unexpected conflict, Nie Tian discovered that there was another world inside a piece of animal bone he obtained when he was one year old, and since then he has started his own path of cultivation in the secret realm.
