Nanglong Souka did what he had to; he let his son go and begged the emperor to let the rest of them go. The emperor knew that the Nanglong family didn't really do anything wrong and punishing the entire family would make him looked like a tyrant (not that he was not one). It might incite another heavy wave of the rebels.
He chose to pardon them, but Nanglong Souka still felt heavy, especially when he told the matter to his grandson and daughter-in-law.
Qin Shie smiled sadly. "There is indeed nothing we could do."
Qin Shie was indeed a smart woman and she knew very well the situation. When she first came here, she was just a prisoner of war, but gradually everything changed and she fell in love with Nanglong Sei. She also has a son and became a happy mother.
Now, everything will change.
Little Soujin didn't really understand what his grandfather meant, but he knew that he wouldn't be able to meet with his father anymore.
