Although Immortal Lord Wu Xin possesses a high-level Immortal Body, her greatest wish has always been to prove her teacher's innocence.
However, being a high-level Immortal Body herself, it's difficult for her to provide proof.
Originally, Cao Zhen seemed to be the best candidate to prove the teacher's innocence.
But it turned out that Cao Zhen was an alien race.
Yet, despite being an alien race, Cao Zhen highly identified with their lineage; he clearly had the chance to kill her but never acted on it.
Furthermore, she could sense that Cao Zhen didn't see them as enemies. The real adversary in Cao Zhen's eyes seemed to be the Blood Clan.
Additionally, it seemed Cao Zhen wanted to return, so why should she regard Cao Zhen as an enemy?
Having figured everything out, Immortal Lord Wu Xin looked at Cao Zhen and slowly spoke, "I don't know which world you belong to, nor am I sure that method will definitely allow you to return. But you can give it a try."
