He shakes his head as he tries to look the way Will and him battle in the future. But to both of their disappointments, they could not even understand these type of level of fights.
Will seems to be attacking Azief from all points of time and Azief seems to be closing each point of time to stop Will from injuring him.
Will right now seems to be able to traverse through each point of time in the Time Stream and all of the multiverse
This fight is not like some punching and kicking fight. Instead it involves laws of the Universe and Concepts of the Omniverse
Unless you are the same levels as them, one could not have understood the intricacies of their fight.
It is not like they could see the hidden attacks; the fancy moves of fighting because they did not use their hands and feet to attack each other.
