Zhang Sangu is a weathered middle‑aged male volunteer in Guan Yi’s group. He describes himself as forty‑six years old, alone and accomplished nothing, so he grits his teeth and signs up as a last gamble. He is pragmatic and asks practical questions about the ethical and legal implications of being pirates in the Secret Realm. He seems more cautious and experienced compared to the younger volunteers. His appearance suggests a hard life, and he is ready to take extreme risks to change his fate.
