At that moment, Zhao Yu realized that he had been wrong. In his hear he blamed himself. He had a premonition of danger but had failed to pay attention to it and now they were in trouble.
However, there was one thing Zhao Yu couldn't understand. Why did the two men dare to expose themselves here?
The Secret Service was different from the police. In a short time, the passage would be surrounded by Secret Service agents. No matter who the two men were, they were undoubtedly seeking their death by doing this. This was really unreasonable.
Also, if this was where the Japanese buried their treasure, why did the men lead Zhao Yu and the others here? This didn't make sense. If they had realized that someone was on their trail, they should lead them somewhere else, not to the secret passage.
