Each galaxy has its own protector god. Jiazizi is the protector god of the solar system. One day, the protector gods of several outer galaxies coveted the solar system, so they joined forces with the protector gods of other galaxies to attack the solar system. Jiazizi was outnumbered, so he could only seal the solar system and the ancient gods. At this point, the solar system entered the Ice Age, and Jiazizi fled alone in search of rescue.
