Lu Jianguo was eating his meal while also discussing with them about how the base was dealing with the polar day. For instance, at the greenhouse, they had installed shade curtains.
After finishing the topic of polar day, Gu Pan timely reminded him, "Dad, you mentioned the polar day, but could there be a polar night? Look, after the extreme cold came the extreme heat, so it's not impossible that after the polar day, a polar night could follow."
Lu Jianguo's hand paused as he was sipping his soup. He furrowed his brow and thought for a moment, "It's not out of the question." He added, "But a polar night is not as easy to deal with as a polar day."
Gu Pan said, "That was my guess as well."
Lu Jianguo responded, "If we prepare in advance, even if polar night does happen, we can manage it."
After saying that, he let out a sigh, "From what I hear from the people above, this disaster might last for many years."
