Under the constant ravages of natural disasters, even these ruins have become incomplete, appearing even more desolate and dilapidated.

Even from the sheer size and extent of these ruins, one could vaguely discern how prosperous this place had once been.

While traversing the ruins, a wall that was only half intact caught the attention of the safety zone.

The plastic doorplates remaining on the wall stubbornly reveal their former glory despite the constant erosion of rain.

"There seem to be words on it." A guard from the safe zone pointed to the wall, his voice tinged with surprise.

"That's right, the words are made of plastic blocks."

"Let me take a look." Wang Lijian, who was at the front of the line, rushed over impatiently.

He stood in front of the wall, carefully examining the words made of plastic.

Although the passage of time and the elements had blurred the characters, after some effort, he finally deciphered them:

"A post station!"

"The sign says 'Relay Station'." Wang Lijian's excited voice echoed through the ruins, his eyes sparkling with excitement.

These are precious traces left by ancient people who once existed.

Surprisingly, the characters used by the ancients are basically the same as those used in their safe zone.

A post station?

Li Yu was puzzled after hearing this. Could this be the place where ancient people rested and ate when they were traveling?

"It seems this place was once a stop on the journeys of the ancients," said Wang Qinshui, the head of the family, as he approached.

His voice carried a hint of nostalgia as he continued to explain to the crowd:

"In that era, the post station must have been an essential place that people visited every day."
