"Ah, don't be afraid. I'm actually just a very weak old man, with only a few years left to live," the old man kindly reassured.
"Now, the internal cycle is insufficient, wanting to leave is understandable, but it's quite unexpected that you managed to reach this level.
As for the higher levels..."
He paused.
"They are no longer effective; there's no need for you to go there."
"What do you mean by no longer effective?" Zhang Rongfang asked.
"It means they're useless, disconnected. This Taoyuan, originally, was meant for communication and exchange of consciousness, intelligence, and martial arts among various interactive zones.
The first three levels can no longer be contacted, naturally making them inaccessible." The old man replied.
"Then what about you? Why are you still here, what do you eat?" Zhang Rongfang asked again.
"I neither eat nor drink, and I won't die," the old man laughed again. "As for why I am still here, it's because if I go out... I will die."
