There was no doubt darkness around him. No matter how strong his vision was, he could not sense any light from any direction.
This was not surprising. The space inside the teleportation door seemed to be able to devour everything. Light did not exist here and Chu Nan was already used to it.
However, ever since he entered the teleportation door, he could not sense any other energy fluctuations. He could only sense the extremely special energy fluctuations that belonged to the extremely deep energy structure unique to the inside of the teleportation door space. They were very stable and were extremely easy to sense but difficult to affect.
Apart from that, he could not sense the energy eruption that he could occasionally sense outside the teleportation door. He could not sense the energy fluctuations of the others who had entered with him, regardless of whether they were strong or weak.
