It was no wonder that Elkart was so shocked. Although with Chu Nan's help, the joint research progress of the Declan Empire and the Noctem Chamber of Commerce in the Endless Abyss was much faster than before, they had recently encountered a very important problem. That was how to hypothesize the teleportation door in the normal universe outside the Endless Abyss.
Through more than a year of research, they knew the basic energy composition of the teleportation door, and they also knew how to inject the corresponding energy replenishment into the teleportation door to maintain its operation. They had even managed to forcefully close it through a special method three months ago.
