Idioms, Halo and Three Thousand Worlds

When an idiom becomes a halo, it has incredible power. Do you want to dance? The swordsmen of the Three Thousand Realms fled away when they saw the rooster, and had nightmares when they heard the rooster crow. You, give your name! Any pretender, masked person, or masked person in the Three Thousand Realms will obediently report his or her surname. The Three Thousand Realms are invaded by Halo, and only Halo can fight against Halo. This is a halo tour!
