Usually, every area was absolutely independent. Nobody could easily cross between areas. Yun Feng didn't know the reason. According to the conversation between the two of them, if she wanted to enter the Central Region, she could only do so through this opening. If she missed this opportunity, she wouldn't be able to enter the Central Region no matter what.
The two of them didn't talk about the opening time between the Central Region and the Inner Region. Rather than saying that they didn't talk about it, it was better to say that they didn't know about it at all. The difference in strength between the three regions was quite huge. The threshold to enter the Central Region was the Lord Level. Even if someone below the Lord Level entered the Central Region, they would only die. They probably wouldn't be able to survive in the Central Region for a long time. This was Yun Feng's understanding.
