Because Northern Heir Xiao Wuji cried poor and asked for military provisions for five years, Empress Su Qingwan traveled incognito to the north to audit accounts, only to find the border brimming with spiritual energy and guarded by paper soldiers. On the surface, Xiao Wuji is profligate and greedy for money, but in secret, he uses his vital blood to summon soldiers through scattered beans and employs millions of paper soldiers to resist the demon tide. Yan Song collaborates with demons, cuts off provisions, and forges imperial edicts. After the Empress's identity is exposed, she joins hands with Xiao Wuji to take control of the Divine Strategy Camp, summon the demon clan, and behead the demon lord, ultimately returning to the capital to settle accounts with the rebellious traitors. Highlights include audit plot twists, spendthrift disguises, paper soldier immortal arts, a human-demon alliance, and sovereign and subjects standing shoulder to shoulder to protect the country.
