Ren Xin once went out and encountered gangsters who were robbing and killing Yuanlu's family. Although he immediately stepped forward and drew his sword to help, he was only able to save Yuanlu alone in the end, and the rest of his family were killed.
Ren Xin brought Yuan Lu back and regarded him as his own brother.Genroku is frail and sick but has a very smart mind. Therefore, although his kung fu is average, he is good at setting up traps and using some of his own invented long-range attack weapons - such as “missile crossbow”. His strength should not be underestimated.
Yuan Lu also clings to and protects Ren Xin like a sister. She is everyone's favorite pistachio in the village.After Sui Ruyi entered the palace, she discovered that there seemed to be a big secret behind the murder of her entire family. Later, she embarked on the road of revenge with Ren Xin, Ning Yuanzhou, and Yu Shisan.
