As the name suggested, the so-called knowledge space was naturally used to learn.
"There's a profound knowledge hidden behind every door you see. You just have to push open the door and you can learn a lot from it." Little Brat encouraged her. "Now, pick any door you want."
But Huanhuan hesitated. She didn't know how long it would take to learn these things. "I want to go out and inform Bai Di and the others first so they won't worry."
If Bai Di and the others saw her suddenly lose consciousness and fall to the ground, they would be very worried.
But Little Brat said, "You can't get out now."
"Why?"
"This space has a limit on the number of times it can be opened. It can only be opened once a month. You have to learn something first or you won't be able to leave."
Huanhuan was speechless. "This place actually makes learning mandatory?!"
