"We need to hurry, we still have to catch a cruise ship in-between, and I hope we can make it before it gets dark."
Bi Fang stuffed the documents and magnetic card back into his inner pocket, zipped it up, and started jogging toward the direction of the seed vault.
[Before it gets dark? Is it far away?]
[We just got off the plane and it was just getting light, right? Is Old Fang planning to run the whole day?]
[Master Fang: I can keep going for a whole day]
[Really? I don't believe it, let's see (lifting the skirt)]
[Are you guys stupid? This is the Arctic, there are polar days and nights, and it's October now, we're about to enter the polar night, the daytime is very short! I estimate only a few hours!]
"That's right," Bi Fang said with a smile, "From November to February every year, within the Arctic Circle, we enter the polar night, there's no daytime, and this is also the most difficult part of my survival challenge two days from now."
