Although Daoist Guang Cheng's sword possessed nearly the speed of light, he himself couldn't achieve such a velocity.
His sword was nearly as fast as light because both of Guang Cheng's swords had been refined from solid to void, essentially becoming a form of light, hence they were capable of reaching such extreme speeds, but his physical body couldn't transform into light, and naturally couldn't match the sword's supreme velocity.
Golden light broke through the sky; it took quite some time to travel from West Kunxu to Yuxu Temple, and by the time he reached Yuxu Peak in East Kunxu, dusk was nearing.
At this time, as nightfall approached, Kunxu Mountain grew three times colder than during the day, with bone-chilling winds blowing in sharp gusts.
However, the climate near Yuxu Temple was in complete reversal with the seasons, permanently fixed in the time of spring.
