October 4th marked the fifth day of the rapid temperature rise, and by sunrise, it was already 38°C.

Meanwhile, the temperature in the underground fortress was just 21 degrees.

Li Fan lay on a sofa on the third basement level, holding a chilled watermelon in his left hand and scrolling through TikTok on his phone with his right, his feet in flip-flops swaying back and forth.

He was waiting for the news. If his memory served him right, at nine o'clock this morning, in just an hour, the morning news would officially announce a high-temperature warning.
