Even when on guard, Zhou Tian could enter the territory of those hostile forces as if entering a land with no one around, and under that circumstance, the Monster at that time was not prepared at all. Thus, if Zhou Tian wanted to confront that King Level BOSS, it was naturally impossible for the lesser monsters under its command to detect Zhou Tian's movements.
As a result, just like the last time, when Zhou Tian stealthily approached the vicinity of that King Level BOSS, the BOSS at that time failed to notice Zhou Tian's presence. It was only thinking about how to act next, always assuming that Zhou Tian's vengeance would fall upon it in the future, not at that moment.
In that situation, seeing that the King Level BOSS was also unprepared, Zhou Tian of course was not going to be courteous. After confirming the situation, he leapt out from the shadows at the first moment and began his assassination of the King Level BOSS.
