When the Liu family is humiliated, they send a warrior named Wu Jing Xue to bring back their son, who was born on the day of the battle of the jiliang tower. When the baby is born, the elder Liu rushes back to the tower to find out what's happened. He originally wanted to kill the enemy himself, but the baby's health has declined due to childbirth, so he's had to isolate the child and his mother for a while. Then, wu ji jing Xue comes back to them again and tells them that he'll bring his mother back soon. He'll also bring his son back soon to reunite the family.
