Tuoshan was located in Luolong County, zhangze city, Xixia province. It bordered Qinshan city, Longxi province, and was part of the Qinling Mountains.
At this moment, in a primeval forest in camel mountain, a biology team from Northwest Agricultural University was setting up tents and camp on the hillside.
The leader of this group was a skinny middle-aged man. His name was Zhang Xinye, a biology professor and a supervisor for Ph.D. Students.
Seeing that the students were setting up camp, he observed the environment around the camp and planned the scientific examination activities in the next few days.
When he arrived at a depression on the south side of the camp, his eyes suddenly lit up and he hurriedly called his companions over.
In the center of the depression, there was a well with a big stone on top of it.
