When Qiu Ren was possessed and entered the divine city, he had already been exposed to Tang Zhen.
He thought that he had hidden it very cleverly and that no one could see through it, which was why he dared to do this.
However, how could he have known that this concealment was completely useless in the eyes of an ultimate existence like Tang Zhen? he could easily see through it with a single glance.
Qiu Ren didn't know how laughable his performance was. Otherwise, he would have been so embarrassed that he would have vomited blood.
Tang Zhen didn't expose him. Instead, he played along and dug a huge hole for Qiu Ren.
He would use the God city as bait to lure Qiu Ren and achieve his goal.
Qiu Ren didn't realize it and thought that he had achieved his goal.
