Apart from Gong Huiyu, Gong Qiang had sacrificed all his adopted kids as test subjects for his gold cultivation. Meanwhile, Gong Rui could only watch helplessly from inside the giant soldier god's body.
Gong Qiang had spared Gong Huiyu only to use him as leverage to control Gong Zhiyu.
As long as Gong Huiyu remained in Gong Qiang's hands, Gong Zhiyu did not dare to retaliate. He needed to protect the one little brother he had left.
Anytime Gong Zhiyu exhibited the least bit of rebellion, Gong Qiang would immediately threaten him with Gong Huiyu.
Gong Zhiyu dared not rage nor flee. He could only obey.
So although he was unwilling to carry out any killings and unwilling to be Ji Fengyan's enemy, he had no choice but to fight on. Only by dying in battle would he gain release and also not turn Gong Qiang onto Gong Huiyu.
