The man's eyes were filled with hatred when he said this.
This was also a reasonable matter. Anyone who was imprisoned in a dark cell with their hands and feet cut off would have an endless hatred in their heart.
In the past few days, the man's mind had been filled with thoughts of being able to break out of his cage one day and kill his enemies with his own hands.
Only by cutting its flesh, drinking its blood, and breaking its bones and sucking its marrow could the hatred in his heart be released!
However, those who harbored such thoughts would probably not be able to take revenge until the moment of their death. Instead, they would die at the hands of their enemies.
The man who was rescued by Tang Zhen was this kind of person. The hatred in his heart was difficult to let go. He also knew that he might not have any hope of taking revenge in this lifetime. Hence, he agreed in such a straightforward manner.
