There were no more piercing cold winds blowing through in the passageway after the outermost stone door had been closed, which blocked the flow of cold wind from outside.
Su Mo kept walking and, after closing the second door, he could clearly feel the temperature rise in the shelter.
It was not until he walked to the main door and opened it that a wave of warmth greeted him.
Compared to the minus seven or eight degrees outside at this time, the four or five degrees in the shelter was practically a kind of enjoyment.
Glancing at the pets who were still asleep, Su Mo walked toward the bottom of the ventilation duct in the crop culture room and peered upwards for a while.
A whirring cold wind was blowing down from the ventilation duct. The temperature in the crop culture room was obviously lower than the other rooms, even lower than that of the living room.
