The Thirteen Swordsmen of the Heavenly Sword Murong Mansion were famous all over the world, but in the end their bloodline withered away, and only the eldest brother and the younger brother were left among the Thirteen Swordsmen.
Murong Du, the sixth among the Thirteen Swordsmen, died in a vendetta. After his sixth brother was killed, his wife Yan Yuqin angrily chased her, but was defended by both fists. When she was seriously injured and fled, she was surprised to find that she was more than one month pregnant. She wanted to return to Murong Mansion, but was ambushed on the road. She fought to the death to win a chance to escape the siege. He hid in the deep forest and gave birth to a son in the home of a herb collector in the forest. He was named Qianqiu because his father was good at making Qianqiu drunk. To avoid being chased by his enemies, he took his mother's surname and named him Yan Qianqiu. Yan Qianqiu was born frail due to the exhaustion during pregnancy, so Yan Yuqin decided to dress her up as a daughter according to folk customs, hoping that her daughter would grow up safely. Three years later, Yan Yuqin's old injury recurred, and he passed away after transferring all his strength to his youngest son. After his mother died, Yan Qianqiu lived in the market and was adopted by Lian Hongmei.
