Void Emperor?
The person who traveled through time and went to the past to harm Han Jue was the son of the Demon Emperor, Void Emperor!
Han Jue remembered this guy. Previously, in the Great Ultimate Hall, this fellow bumped into him and even developed hatred towards him.
After finding the real murderer, Han Jue started cursing the Void Emperor without another word.
As he cursed, he thought curiously, "The system can defend against enemies who crossed time?"
A line of words appeared in front of him.
[The system can only guard against enemies on the current timeline.]
In other words, the Void Emperor had only gone back recently.
Could the system guard against future enemies?
[That depends on whether you have the system in the future or whether you are willing to help the current you.]
In other words, Han Jue could only deal with the enemies at the current time.
He couldn't help but ponder.
