The water rushed past, gurgling.
Tang Wen, Hu Yun, Feng San Niang, and their party returned to the familiar Underground Palace.
An underground river flowed through, bringing with it a clean water source and fresh air.
This place was more than three hundred meters below the surface.
Even if a Fifth-Grade Powerhouse passed by and probed the earth with their Spiritual Power, they wouldn't discover anything unusual.
However, that wasn't an absolute guarantee.
After all, there was still an opening leading upwards.
If someone happened to detect it, they would realize the space below was empty. With a little more attention, they would discover people were hiding down here.
It was far from safe.
Tang Wen looked at the Stone Dragon. "Block the entrance."
The Stone Dragon shook its body and slithered upwards.
Tang Wen added another instruction, "Seal it completely, but leave a small space every hundred meters."
The Stone Dragon shook its head, taking a moment to understand.
