Guo Liang was killed at the end of "Biyou Village". Guo Liang works for Ma Xianhong, the head of Biyou Village. He followed Ma Xianhong for many years and came to Biyou Village earlier than all the root people, so Ma Xianhong relied heavily on Guo Liang, asked him to test Zhuge Qing and invited him to Biyou Village.

Guo Liang is an alien transformed from ordinary people, whose whereabouts are uncertain. Even when I was in senior three, I couldn't find his whereabouts. There are different opinions about Guo Liang's identity. From the analysis of Guo Liang's characteristics and experience, he is the heir to the concept of cave mining, and he is favored by Ma Xianhong because of his unique skills.

Guo Liang accepted Ma Xianhong's arrangement and invited Zhuge Qing. Guo Liang left before the temporary workers entered Biyou Village. In addition, the relationship between Guo Liang and Qu Tong is also unusual. When Ma Xianhong asked about Guo Liang's whereabouts, Qu Tong said that Guo Liang had gone home, so Qu Tong must have a certain connection with the descendants of the cave-mining concept. Finally, Guo Liang's body was found. This is because the person who took Ma Xianhong chose to kill him to prevent his identity from being exposed.
