Yang Chen was clearly looking at Li Yelai, but Li Yelai felt as if Yang Chen's gaze was not really on him.
It seemed as though he was looking through him at someone else? Or perhaps some people?
"Is he thinking about those colleagues who sacrificed themselves?"
Li Yelai sighed in silence, tactfully choosing not to disturb Yang Chen.
Instead, he continued to train in swapping his "Face."
Every time Li Yelai used or switched his "Face," he had to raise his hand to his face. This was to allow the Spiritual Energy on his palm to gather or change the "Face" more quickly.
The good news was that he didn't need to touch his cheek; he could activate or switch the "Face" even from four or five centimeters away. There was no need to worry about obstructing the activation with a mask or helmet.
However, this was an unavoidable starting gesture. If his arm were injured or he was holding a weapon, it would be problematic.
