"Kid, there's no need to be afraid. Just answer a few simple questions. Not only will I spare you, I'll let you go," Zhang Tie said kindly.
"Yes, sir. As long as I know it, I'll tell you everything," the youth replied, still panicked.
"Tell me: who are you people? Who captured you? And where are you being taken?" Zhang Tie immediately began questioning him.
Just as he had said, the youth answered without hesitation as long as Zhang Tie asked something he knew. After half an hour of questions and answers, Zhang Tie watched the youth's departing figure with a thoughtful expression.
After questioning the youth, Zhang Tie had finally grasped the general situation.
The people imprisoned in the carts were descendants born from humans and other humanoid races.
The youth did not know much about the so-called humanoid races. They were called that simply because everyone else called them so. However, Zhang Tie guessed that they were the descendants of humans and transformed alien races from before the laws of this world restricted transformation.

At that thought, Zhang Tie decided to visit the human settlement. Any humans who could still survive in such an environment had to be quite powerful. Perhaps they possessed some inheritance specifically for body cultivation, or rare treasures of heaven and earth.
