"It is said that in ancient times, a divine weapon capable of destroying heaven and earth was born. It was called Tiger Soul, and its first owner was one of the known ancestors of humanity, Chiyou."
"After obtaining this divine weapon, Chiyou's strength increased greatly. He crushed many tribes, even the gods, and became the leader of the Eastern Jiuli Tribe, ruling over a region with immense power."
"One year, Chiyou observed that natural disasters possessed great destructive power, which inspired him to create a set of astonishing saber techniques known as 'The Seven Deadly Limits.'"
"The term 'Heaven and Earth' is derived from the first two moves of The Seven Deadly Limits: 'Swallow Heaven' and 'Destroy Earth.' This saber technique can harness the power of nature to move mountains and fill seas, producing unimaginable phenomena that can alter reality."
"Thus, throughout history, this saber technique has been called The Seven Deadly Limits of Heaven and Earth."
