"In order to keep the secret, they even killed their own people," Cui Lizhu exclaimed.

Zhao Yu frowned, saying, "I'm curious. Your father had never been abroad. How could he find out these things about Japan? Was he doing this on his own? Or was all of this just hearsay?"

"My father had always worked on his own," Cui Lizhu explained. "The only person he might call a friend were the people that helped him unload his stolen goods. And I don't think what he wrote is hearsay. It's possible to kill in order to keep a secret. After all, it's about the fate of the country. It's worthwhile to them kill a few officers and even a few generals. A secret is a secret. The fewer people that know it, the better. And, what they buried was not only those treasures, but also gold."
