A moment ago.
After traveling for more than 10 days, they had finally arrived at the foot of the mountain of their destination.
It was definitely a treacherous journey. Nathan thought that if he and Regina were alone, they would definitely take at least 20 days to reach this place. They needed to make a few stops to fully recover their strength.
After all, they had to take down 5 elite class aliens just to reach this place.
Once they reached the mountain, finding the entrance was not that hard, especially with the help of Luna's golems. She spread them out and let them find the entrance, which didn't take over 40 minutes.
"This is the Endless Prison?" Nathan lifted up his gaze. There was a cave at the foot of the mountain. When they entered the cave, they found a massive door at the end of the cave.
Despite being abandoned for hundreds of years, the gate seemed to maintain its sturdiness.
