Wanqing was startled by her own thought.
Xu Zhentian was still alive?
It was only her guess!
She thought, since Ji Shang was helping her, or more precisely, was helping her husband, there should be no reason to actually have killed Xu Zhentian, because he knew that killing Xu Zhentian wasn't helping her husband but was indirectly harming the Su Family.
So, there must be some unknown secret behind this.
Could it be that the Xu Zhentian in the police station wasn't the real Xu Zhentian?
Beheaded corpse...
Wanqing's mind raced. Beheaded, leaving behind a body similar to Xu Zhentian's could indeed be possible.
A substitution of the prince?
Wanqing laughed. This was definitely a prince substitution tactic. The real Xu Zhentian must still be alive, just hidden by that Ling Wei, while the headless corpse in the police station was just a substitute. Without a head, who would care about his body?
Is this their National Security's method?
