What is the relationship between Shan Zhigang and Stena?

Stearns submachine gun is a fantasy drama directed by Li, starring Wen, Dai Xi and others, especially Wu Junru. In the original novel, Shan Zhigang is a good friend of Qin Fang, an ordinary person, with no drama, and has little to do with Steng. However, in the TV series, his profile was revised.

Akiyama, who was already old, saw many compatriots die in Hangmen one after another, fearing that Si Teng would harm the world. But Steven came from his mutation, and he devoted his life to killing Steven. So I chose to eat what I used for rattan, but I changed back to myself when I was young, so now Shan Zhigang is Akiyama.
