Shadow Thirteen was indeed thrown into the mass grave back then. Seventeen or eighteen half-sacrificial soldiers were abandoned with him. They were splashed with kerosene and only the sound of their bodies being burned was left when they were burned.
Shadow Thirteen was the only one who escaped, but he did not last long as the poison took effect. He lay by the roadside and waited for death. At this moment, Yan Jiuchao passed by him.
Yan Jiuchao squatted down and asked him, "Do you know how to fight?"
"Yes." He said.
"Are you afraid of killing people?"
"I'm not afraid." He said.
He was picked up by Yan Jiuchao. Yan Jiuchao ordered someone to treat his poisonous pill, and then he naturally became Yan Jiuchao's secret guard.
They were both sacrificial soldiers from the sacrificial soldiers camp, but Shadow Six was much luckier than Shadow Thirteen.
