Su Qinghe, an archaeology intern whose thesis was stolen by her mentor and who's been pushed to the brink by harsh reality, unexpectedly receives a night-shift offer from the 'Shanhai Museum': salary of 100,000 RMB per month—just one condition: no fear of darkness, no fear of ghosts. She thinks it's just a lifeline—until 3 a.m., when she witnesses a terracotta warrior shedding tears, ancient artifacts' spirits awakening, and a bronze Pixiu choosing her as its master.
