In Duke Zhen's Mansion, within a secret chamber.
The surrounding walls, made of Black Iron, were air-tight, with very little light to speak of, a darkness so complete that only an Ever-bright Lamp provided a scarce amount of illumination in this pitch-black room.
Duke Zhen Guo, Cheng Shiyuan, supported the body of Cheng Guang as he slowly walked into the chamber.
The sorrow that once filled his eyes gradually receded and disappeared upon stepping into the chamber.
He placed Cheng Guang onto the bed.
Examining Cheng Guang.
Something was strange.
"Grandson, your methods are quite peculiar. Although your body has sustained numerous, severe injuries, they don't seem to reach your core; most are superficial," he said.
"At the same time, there seems to be a force that is repairing your body. If you weren't actively suppressing it, the injuries you have would have mostly recovered by now."
