Getting people there

Ning still couldn't understand what the system was saying. How could time move fast and yet not? He had a hard time conceptualizing it. 

"Sorry, can you explain in a clearer way? I still don't get it," Ning said. If time really was moving at 13 times the speed, he should have noticed many day and night cycles, which he wasn't. 

<Only 13 time is moving fast. Meaning, while everything the same for you, you are now aging times faster than outside of this island>

"Wait, so it had something to do with my perception then?" Ning asked.

<No, time itself is moving normally for everything else; they are only aging faster>

"Hmm, I think I understand what you mean… in a sense," Ning said. "So, 1 day in here is 1 day outside, but I will age by about 12 more days if I stay in here, right?"

"Sigh, I will have to warm them then. I don't want them aging faster just to negate the years they get by breaking through here," Ning said.
