"Wu'er, all these years, why didn't you come home?" Hua Lao's voice carried a hint of reproach. Hearing this, Hua's father bit his lip and said, "Dad, I'm sorry!"
Hearing these words, Hua Lao patted Hua's father's shoulder, teary-eyed, "Wu'er, it's not your fault. It was the traitor in your team who informed the enemy of your actions, causing your brothers to be annihilated, so it's not your fault."
Listening to Hua Lao, Xiao Yifei understood that Hua's father did not return home because he felt guilty. Indeed, this was the case. During the defense of the border, Hua's father and his brothers planned to flank the enemy from the rear, resulting in total annihilation and leaving insufficient men to defend the border, allowing the enemy to invade.
Hua's father survived because a kind fisherman saved him, but one of his legs lost all feeling.
