Developer

"Oh," the host got a little curious. "Is that so? So you believe the reason no one can visit the fifth continent is that the developers haven't fully made it yet and it is still under development. That kind of makes sense."

"Doesn't it?" Hannah said with excitement. "Imagine later down the line we reach the saint realm and have to go up, and the only way to do that is to move to the fifth continent where there will be much stronger people, better techniques, and all the pills and weapons and artifacts. It will truly be an amazing time."

The host talked with the guests about the fifth continent for a little longer before saying that the talk with them was over and going on a break. 

Alex was still taking in the pieces of information he had just gotten. "I didn't know there was so much more to the world of Eternal Cultivation. And here I am staying in one city in one empire in one continent," he said out loud.
