Tang Zhen did not hear the red-robed old man's furious roar. He did not know that the other party had already confirmed his identity as a participant.
In fact, this was also a reasonable matter. According to Tang Zhen's analysis, the trial-takers in the Soul Master world were definitely not just him and Luo Fei. Perhaps some careless guy would accidentally let the Soul Master check his background and expose the information that he came from the Lou Cheng world.
Of course, it didn't matter even if he was exposed. The other party only knew that he might be a cultivator from Lou Cheng, but he didn't obtain the soul aura of this body. In other words, Tang Zhen was still safe for a short period of time.
As long as he kept a low profile and tried his best not to let anyone discover his abnormality, it would be fine.
