It was already November. The desert was not hot, but the temperature difference between day and night was very large. The temperature was acceptable during the day, but it was very cold at night, the kind that could freeze humans to death.
Tan Rou and the others tried their best to search for them during the day. At night, their field of vision was limited, and they were likely to encounter wild mammals in the desert, poisonous snakes, and insects. If they encountered them, Tan Rou and the others would be in trouble.
Tan Rou held a tablet in her hand. There should be no signal in the desert, but Tan Rou's tablet could still be used in the desert.
