Gu Xinchao stole a portion of the memories of Danzhusheng from the Blood Shadow Sect, and these memories were related to the Hundred Thousand Great Mountains.
Back then, Danzhusheng traveled from the Star Sea to the Hundred Thousand Great Mountains, intending to seize Nie Haihua to serve as the core of a magical treasure. To this end, he had conducted extensive research on how to reach the Hundred Thousand Great Mountains, how to break through the barrier of Nie Haihua, and how to swallow the target.
The entire plan went very smoothly, although it did not end with the best possible outcome, as he failed to completely control and then devour the true form of Nie Haihua.
