"In your dreams!"
As Zhou Tian had predicted, the Human Emperor bluntly refused Zhou Tian's recruitment. After all, the Human Emperor was at that moment an existence not weaker than Zhou Tian, and asking him to give up everything and join Zhou Tian was an unlikely scenario. Zhou Tian's proposition was merely a spontaneous attempt at testing the waters, hoping that the Human Emperor would join his camp, but with no actual loss for Zhou Tian if he refused.
However, even though the result of the test was as Zhou Tian had anticipated, he was still somewhat unhappy. After all, he had genuinely wished for a peaceful coexistence with the other party, but the Human Emperor had firmly decided to oppose him. Thus, although Zhou Tian was reluctant to excessively battle other forces, he wouldn't mind teaching the Human Emperor a lesson since he had dared to obstruct his path at that moment.
