There is a mysterious place in China called Qinghai. It is called "SA Wenbu" in Tibetan, which means the blue sea. In the winter of 1995, a team of explorers came to the Qaidam Basin in the northwest of Qinghai Province. They were appointed by the company to set out from the Qaidam basin to Qinghai, which has been inaccessible since ancient times, looking for a mysterious treasure. In the process of searching for this mysterious treasure, they met many unimaginable things, such as the transparent wall floating in the air, the Kui born with children and mothers, a stone from the sky, a gate leading to nowhere, and what secrets are hidden under these ancient tombs?
