Shen Zhao was originally an orphan of the former royal family. He was falsely accused of collaborating with the enemy, demoted to slavery, and suffered all kinds of humiliation. That night she lit a beacon tower, used blood as ink and fire as an oath, activating the royal secrets that had been dormant for thousands of years, and actually traveled to the troubled times a hundred years later. She kept her name anonymous, lurked in the army as a craftsman, and secretly reorganized her old army. Little did she know that the mastermind who framed her back then was actually the cold-faced general Xiao Yan who now holds military power - an enemy who once executed her people with his own hands, but now he is pressing on her step by step and secretly protecting her. The flames of war are not extinguished and the truth is not yet known. She must choose between revenge and redemption, and the tampered history is quietly waiting for her to rewrite it with her own hands.
