The Mummy: Tomb of the Dragon Emperor

In ancient China, a brutal and tyrannical warlord, Emperor Han, unites the country's Seven Warring States into an empire and becomes the Qin Shi Huang. He orders the construction of the Great Wall of China to bury and curse his dead enemies, eventually learning power over the traditional Chinese Wu Xing elements of fire, water, earth, wood and metal. Emperor Han soon grows fearful that his death will end all he has accomplished and summons Zi Yuan, a Magician (fantasy) who is said to know the secret of immortality. She seemingly casts a spell on Han in Sanskrit, before he executes General Ming, his trusted friend and Zi Yuan's secret lover. He stabs Zi Yuan with a dagger, but having foreseen this event, she immolates and imprisons the Emperor and his soldiers in clay, transforming his army into the Terracotta Army, and flees.
