Su Ling, a modern migrant worker, accidentally transformed into a maid in an ancient palace. When she was framed for theft and expelled from the palace, she discovered the space of the royal tomb left by the previous prince. The thousand-year spiritual energy in the space nourishes the entire underground dynasty, and in the tomb sleeps a frozen prince who uses his soul power to impart martial arts. She refined the underground palace to unlock the secrets of the mechanism, subdued the Millennium Puppet Corps, used emperor-level forging skills to create magical weapons, and used the compass to crush the envoys from various countries in the imperial examination room. When the prince stepped her into the dust with his own hands, she sacrificed millions of evil soldiers in the underground palace to reveal the truth about the usurpation of the throne - the powerful prince sitting on the throne in front of her was just her great-great-grandson. In the end, she rebuilt the dynasty's infrastructure and built the Great Wall of steel with reinforced concrete.
