Gate of Two Realms

"What? What do you mean?" she asked. 

Ming Yue didn't quite understand what the Grand Elder meant. Rather, she didn't think that it'd be like this. 

"Indeed, the place that the High Council has allowed you access to is beyond that gate. Normally that gate leads to the Empyrean Paradise, a small world with energy pure enough to allow anyone to breakthrough with ease. However, that place is just a by-product of something else. After all, that energy has to come from somewhere."

As the Grand Elder explained, he stepped away from his desk, walking towards the back corner of his office. 

He placed his hand on it which seemed to activate something as the walls clanked. A part of it suddenly opened up, revealing a hidden passage where he gestured for her to enter.

Ming Yue obliged, following him into the passage. The hidden door promptly closed when the both of them were inside.
