Soon, Lin Zichen followed Liu Chuanwu into the office.
Shen Qinghan and Song Yuyan also came in.
Liu Chuanwu sat down at his desk, turned on the computer, opened a video folder, and played a video he had shot in an underwater ruin 20 years ago.
Lin Zichen stood behind him, watching the video on the computer screen.
As the video began, Lin Zichen's eyes were greeted by an underwater cave entrance.
It seemed to be over a meter in radius,
located within a coral reef.
The area around the entrance was barren, without even a single blade of seaweed visible, making the entrance obvious to anyone passing by.
Quickly, the footage began to delve deeper into the entrance.
About ten seconds later,
the video transitioned from the cramped cave tunnel to a spacious cavern.
The cavern was empty, with nothing inside.
There was only a huge mural.
