What's the real identity of dad Ma Pan in Tomb Raider Notes?

In Tomb Raider Notes, Papa Ma Pan's real identity is an old hunter in Banana Town.

A few decades ago, Chen Wenjin led an archaeological team to look for Yangjiao Lake in Bajiao County, Guangxi. At that time, my father Ma Pan was the most flexible hunter, so he became the guide of Chen Wenjin and helped them find Yangjiao Lake. However, because of the food brought by the archaeological team, my father Ma Pan killed the expedition and became the shadow that my father could not get rid of for many years.

Dad Ma Pan was finally killed by a ghost, because Wu Xie found out that Dad Ma Pan had killed everyone on the team. The ghost was afraid that Wu Xie would ask Dad Ma Pan why, and Dad Ma Pan leaked his secret to Wu Xie, so he killed Dad Ma Pan.

Extended data:

Dad has a Kirin tattoo, but he has nothing to do with it and is not a member of the Zhang family. On the contrary, there is a custom where Ma Pan is located. A special medicine is boiled into liquid and then used to tattoo children to prevent people from getting sick. Once the person with this tattoo gets sick, the tattoo will change. Later, a feng shui master changed the tattoo of the local people into Kirin. Therefore, Ma Pan also has Kirin tattoos.
