I Have a Sword That Can Cut the Sky

Dongfang Anai is the third child of Dongfang Xiaolin, the lord of Hongye City in Lanwu Continent. He has been frail and sick since he was a child and unable to practice martial arts. While going out to relax, Dongfang An accidentally slipped and fell off a cliff. When he woke up, he found himself lying in a cave without any scars on his body. Then, he saw an old man in sackcloth appearing in front of him. After some conversation, Dongfang An finally understood what happened. This old man was Tian Yunzi, the Supreme Elder of the Tiandao Alliance. While hunting down the junior Martial Emperor who he thought was called Patriarch Wuxiang, he discovered the dying Dongfang An hanging on a tree. After Tianyunzi rescued Dongfang An, he discovered that Dongfang An had a rare pure Yang physique. Later, Tianyunzi sealed the soul of the Wuxiang Patriarch in Dongfang An's body using the ancient Pure Yang Formation.
