Chapter 84: Episode 10: Soul & Magic Mech

 Feng's extensive explanation about how the soul can be created came from his own memories. He was after all a powerful expert that managed to kill a heavenly emperor. He also was the owner of the soul line of evil. Feng had interacted more with souls than living beings.

"Master, I finally understood why the process of a robot forming a soul is partially the same as reverse engineering"

Dracula was an intelligent robot. Hence, he managed to catch on to what his master was saying.

"Oh, go on explain your thinking to me," Feng said. He wanted to know whether his robot really understood what he meant. After all, Feng did not want his robot to be misled. Furthermore, Feng felt that his way of explaining was too ridiculous.
