Duzem turned around and tapped on the skull of prototype number two, which quickly spun and expanded, and in an instant, grew to about a meter in height, utterly engulfing the other parts of its body structure diagram.
The bone patterns on the skull were clearly visible, mixed with different contents of magic text and talismans, but the suddenly enlarged head made Zheng Qing feel as if a fully grown Flying Goblin was lunging at him, causing him to instinctively lean back a little, then immediately realize and abruptly stop, a slight embarrassment appearing on his face.
The other people in the room didn't laugh at the boy's little gesture but focused intently on the skull, including Old Yao.
"——Where does the difficulty in developing a control system lie? Complexity!"
