If the war had ended as it was initially supposed to, the NPCs and the Human Emperor wouldn't have suffered any significant loss. But now, if the war truly ends this way, those two powers absolutely wouldn't agree to it no matter what.
What is the situation at this moment?
The Human Emperor who initiated this war did so intending to annex either Zhou Tian's or the group of NPCs' territories. Although the three sides are currently in a state of balance, each of the major powers secretly harbored the desire to annex the other two.
Under these circumstances, when the Human Emperor waged war, and they took action, they found that Zhou Tian, who was once roughly equal in strength to them or at most slightly stronger, had suddenly far surpassed them. Due to this, the Human Emperor and the NPCs felt extremely uneasy about Zhou Tian's performance.
