This was naturally far from the first time Chu Nan had shuttled through the teleportation door.
However, this was the first time he had shuttled through this clearly unstable and completely formed teleportation door. As soon as he entered the especially dark starry sky, he immediately felt the discordant and irregular up-and-down fluctuations of the energy fluctuations transmitted from the surrounding space.
Moreover, he could clearly sense that the energy fluctuations in this special space were starting to weaken to a small extent, proving that although this teleportation door had maintained itself for a long time, it was still irreversibly assimilated by the positive space universe and would completely disappear sooner or later.
