The Tetra-War Bronze Chariot was Li Qiye's carriage for millions of years. In many eras, the moment the Tetra-War Bronze Chariot appeared, the Gods had to retreat and even existing Immortal Emperors had to greet Li Qiye in person.
Li Qiye gifted the Tetra-War Bronze Chariot to Min Ren's foster daughter and it became defining treasure of the Cleansing Incense Ancient Sect. Unfortunately, she did not pass down the method to ride the Tetra-War Bronze Chariot so even though it was an unparalleled treasure, no one in the history of the Sect was able to ride it to battle.
The Tetra-War Bronze Chariot was stollen from the Cleansing Incense Ancient Sect by the Heavenly God Sect, who later gifted it to the Azure Mysterious Ancient Kingdom, but they also couldn’t find how to use it.
Ancient Sky City
The Tetra-War Bronze Chariot ended up in the hands of Azure Mysterious Ancient Kingdom's Qingxuan Yuanhe, who engraved Refined Jades into the Chariot to move it. Qingxuan Yuanhe used the Tetra-War Bronze Chariot as his carriage in the Ancient Sky City during attack on the Nine Saint Demon Gate's grotto, but Li Qiye took it away.
