Time is also known as the flow of light.
In the river, the flowing light is time, and this is the Long River of Time of the universe where the Wizard World resides.
Generally speaking, without a Saint Position, one cannot reach this place.
Mr. Xu Jing was naturally not an ordinary person.
The only exception was him, a person from the immortal gods civilization, who could enter the Long River of Time of the universe where the Wizard World existed.
This indicated that the High Council of Wizard's Civilization's five Saints did not oppose Mr. Xu Jing's action.
Hence, Mr. Xu Jing was able to step so effortlessly from the Wizard World Homeland into this Long River of Time.
The faint light emanating from Link was the "Life Light" mentioned by Mr. Xu Jing.
Where one has walked, traces are left.
