Thirty Miles Are Missing from the Classic of Mountains and Seas

Dongcheng County is trapped in New Year's Eve for thirty-eight years. Every time it is midnight, the bell rope breaks by itself, the dead wake up, and the child dies again. The road monument outside the city reads: Three hundred miles to the east, it is called Swaggering Mountain. But Yan Yu measured it thirty-seven times and found that it was only two hundred and seventy miles. In the Classic of Mountains and Seas, thirty miles are missing. What is missing is not the road, but the name. Thirty-eight years ago, he personally signed four words on the map: The calibration is correct.
