Darkness was like the abyss. It could not see the end nor the light. Shen Lian was like a fish, moving in the dark, not knowing how many reefs there were.
The Primeval Demon, the variety of reefs or rushing water, wanted to eliminate him. However, Shen Lian did not have any thoughts and was able to avoid those reefs. He went with the flow and did not receive any damage.
The darkness was his heart. His heart was also occupied by darkness but his consciousness could move forward into the unknown and sinister darkness without any damage. It was not easy and he was not proud of his accomplishment.
Soon, it appeared a Daoist Palace. Its plaque was written 'Yuxu Palace'. Shen Lian never saw these three words before but he understood the meaning.
Any living being would be able to recognize these three words.
