By looking at the strings connected to the River of Destiny, Di Tian could guess that he was using the power of fate to guide his reaction speed. This river contained the lives of all people that have existed since the creation of the Heavenly Abode World.
From ancient to modern times, the number of people is simply uncalculable given how short mortals' lives are.
And having these people dictate Wang Wei's reaction is like having an infinite amount of people looking out and reacting for him, thus drastically increasing his reaction time.
The only limit to such power is how much his body can bear.
Di Tian's eyes showed a slight smirk. So what if his opponent could barely react in time with his attack? This did not change the vast difference in their strength or prowess.
He rushed towards his opponent and punched. The two fists clashed together, and Wang Wei felt a strange force entering his body; this was not physical force but something else.
