Plane Dimension

Jiang Ming felt his soul was passing through numerous obstacles, almost like he was being guided to a pathway.

Time slowly passed by, and he could finally see some light flashing at the front.

His soul transformed into his human form as he found himself landing in a Plane Dimension.

'Hmm, plane dimension huh. What an interesting finding.' Jiang Ming thought.

A plane dimension could be explained as the cultivator's inner world. It's a dimension formed through the cultivator's consciousness and was recreated through their imagination.

In other words, it was a cultivator's most sacred place. Thus, Jiang Ming couldn't help but feel perplexed by the owner's desire to share his sacred place with strangers. 

Strangers were just a nicer term to describe them since they would be regarded as intruders in a more accurate term.

They had intruded on their ancient ruin with hopes of obtaining treasures.
