The Tian Cong Yun Sword, also known as the Kusanagi Sword, is said to have been obtained by Susanoo from the tail of the Yamata no Orochi after he defeated it. However, true to the nature of the Fusang people, its power is exaggerated countless times in the myths.
Regardless, the Tian Cong Yun Sword is considered the mightiest Divine Artifact of Fusang legend and one of Fusang's symbols, so it must possess some unique traits.
Certainly, the Sun God's purpose in seeking the Tian Cong Yun Sword was simple, to allow the Bow of the Sun God to ingest the Divinity of the Tian Cong Yun Sword.
