Tianlan Ballad

Hongdou, an abandoned baby in a remote inn, was unwilling to live a life of living in an inn. When he was sixteen, he left home with the Kuchan Mountain people and changed his name to Dou Xin. After accidentally killing his master during the resistance, Dou Xin made a life-and-death contract with the ancient sword that had been lost for thousands of years, and step by step fell into the long-predicted thousand-year war.
