Gu Yuanqing's heart jolted.
He had never imagined that peering into the source of the Dao River would reveal someone else.
Before he could speak, that person's thoughts came through their locked gazes once more. He gave a soft sound of surprise and said, "The future or the past? How interesting."
Gu Yuanqing's pupils contracted. Within his sight, a phantom outline began appearing around those eyes, as though a face were about to emerge from nothingness.
His Dao heart throbbed violently, and an inexplicable sense of danger arose.
He abruptly closed his eyes, but even that seemed unable to stop this person from appearing.
Only then did he suddenly realize that this person was not manifesting in the void at the end of the Boundless River. He was appearing directly within Gu Yuanqing's thoughts.
Closing his eyes had no effect whatsoever.
Karma!
Gu Yuanqing instantly understood the reason.
When he looked toward the source of the Boundless River, he had used it as a spatial anchor to meet the gaze of a Great Cultivator in an unknown stretch of space-time. Karma had formed between them of its own accord. Even if their gazes were cut off, that karma was difficult to sever.
Someone capable of this must possess attainment far beyond a Celestial Immortal.
Gu Yuanqing arrived at a rough judgment in an instant. Although Celestial Immortals had some contact with the Great Dao of time, most merely brushed its surface through the evolution of space.
For example, the changes in the Heavenly Human World known as Seas Change into Mulberry Fields, and the difference between that world and external space-time, involved a slight contact with time. Yet at its root, it was merely an acceleration of the changes undergone by all things within that space.
