The Six Gates Formation was one of the common military formations used by the Great Yu's army. Its structure was similar to that of the Six Flags Formation used by immortals.
The Six Flags Formation used by immortals could be divided into illusion array, maze array, trap array, murder array, and many other different attributes; but, the Six Gates Formation was different. After being studied and modified by Great Yu's Military Court and Directorate of Celestials, this formation was full of endless transformations, deadly traps, and restrictive magic. As a matter of fact, it was a formation created purely for the purpose of killing people.
